v6 Gearbox options

[boostedbatman]

I am chasing any info on the v6 JDM gearbox labelled LZ (G561 casing) it has added LSD and I am soon to pull the bugger apart. I have been unsuccessful in tracking down any information on this at all. So those with nothing to do and a bit of net searching experience may feel that they wish to help the poor Batty out. I can find NO info on the box or the LSD so feel free to give it a go!!
Anything at all will be great and I mean anything

[CRA23]

i posted this a while ago, i had another search and came up with even less

the lsd is called a screw refuse, some sti's came with it and some gt starlets

"The system which restricts the differential motion of the left and right driving wheel the screw refuse coupling (the multiple disc clutches) due to function, transmits power of the engine to the road surface without wastefulness. It improves takeoff characteristic and travelling stability"

[CRA23]

i also found that kaaz use to make a 1.5 way lsd but stoped it cos it didnt well much

also screw refuse is the tanslations that google tanslate gives me from this "????" so if u some one can read japanese it might give up a better answer

"The screw refuse LSD, differential control of the diff. is done making use of the viscous torque of the oil, screw refuse coupling unit was used, the LSD of rotary response type.

Generally, in center of the tire left and right, when rotary difference occurs in the tire of left and right two, absorbing that, there is a differential Lu gear which it tries to be able to run smoothly. But when the tire of one side races to the diff., there is a fault that driving force is directed to all there. When the LSD is something which prevents that, the on one hand tire races, you hold down that, already convey driving force to also the tire of one side. Utilizes the viscous torque of the oil as for the screw refuse LSD which, differential control being smooth, the quiet point merit."

"The LSD is roughly classified to rotary response type and the frictional type which uses the gear and the clutch. Frictional system furthermore is classified into residual pressure type * multiple plate type * torque proportional systems and the like. As for representation of rotary response system the screw refuse LSD which utilizes the screw refuse * coupling Frictional system mechanical cable type and the multiple disc clutch LSD which are said generally and the torque sensing LSD which utilizes the resistance of the gear (the To Lu plug LSD , can call the helical LSD representation.
Generally, in the car for general travelling the screw refuse LSD in the advanced sport car the To Lu plug and the helical LSD are adopted."

some of nismos and trds lsds are screw refuse
most of the screw refuses lsds i have found are for fwds

ビスカスLSD
Screw dregs LSD

ビスカス LSDとは、オイルの粘性トルクを利用してデフの差動制御を行う、ビスカスカップリングユニットを使った、 回転感応式のLSD。
Screw dregs LSD of the rotation induction type using a screw dregs coupling unit which performs differential control of DEFU with LSD using the viscous torque of oil.

一般に、左右のタイヤの中間には、左右2つのタイヤに回転差が生じると、それを吸収してスムーズに走れるよ うにするデファレンシャルギアがある。しかしデフには一方のタイヤが空転すると、駆動力が全てそちらに向け られてしまうという欠点がある。LSDはそれを防止するものであり、一方のタイヤが空転するとそれを抑え、 もう一方のタイヤにも駆動力を伝える。オイルの粘性トルクを利用するビスカスLSDは、差動制御が滑らかで 静かな点が特長。
Generally, when a rotation difference arises into the tire of two right and left, there is a differential gear which absorbs it and enables it to run smoothly in the middle of a tire on either side. However, when one tire races to DEFU, there is a fault that all driving force will be turned there. If LSD prevents it and one tire races, it will stop it and will also tell driving force to another tire. For the screw dregs LSD using the viscous torque of oil, a point quiet about differential control being smooth is the feature.

Limited Slip Defferential Gear（差動制限 デフ装置）の略称
The abbreviated name of Limited Slip Defferential Gear (differential restriction DEFU equipment)

決していけないオクスリの LSDではない。
OKUSURI which cannot be settled It is not LSD.

自動車は旋回時に内側の車輪と外側の車輪の軌跡の長さに差(内輪差)が生じるが，吸収するため Defferential Gear(俗称： デフ)と呼ばれる差動ギアを装備している． デフの働きにより，内側よりも軌跡の長い外側の駆動輪に駆動力を多く配分することで，スムーズな旋回を実現している．
Although a difference (inside difference) produces a car to the length of the locus of an inside wheel and an outside wheel at the time of revolution, in order to absorb . which has equipped the differential gear called Defferential Gear (common name: DEFU ) DEFU By work, rather than the inner side, it is distributing many driving force to the driving wheel of the long outside of a locus, and smooth revolution is realized.

しかしながら，自動車競技でのコーナリング操作や悪路走行時などで一方の駆動輪が宙に浮いてしまうと， デフの働きにより，接地している方の駆動輪よりも宙に浮いている方の駆動輪に駆動力が配分されてしまう．その結果，浮いた駆動輪が空転するばかりで接地輪が回転しないので前に進まないという現象が発生し，コーナリング速度が低下したり悪路でスタックしたりなどの悪影響が生じてしまうことがある．このような現象を改善するため， デフの動作を制限して駆動輪の空転を抑止したものが LSDである．
However, it is DEFU when one driving wheel floats in the air in the time of the cornering operation by automobile game, or a bad road run etc. By work Since a grounding ring does not rotate about [ that . by which driving force will be distributed to the driving wheel of the direction which has floated in the air rather than the driving wheel of the grounded direction, consequently the driving wheel which floated race ] the phenomenon in which it does not progress in front -- generating -- cornering speed falling or carrying out a stack on a bad road たり -- etc. . which a bad influence may produce -- in order to improve such a phenomenon -- DEFU What [ restricted operation and deterred idling of a driving wheel ] It is LSD.

■ 回転感応式 LSD
■ Rotation induction type LSD

回転感応式は左右輪(センター デフならば前後車軸)の回転数に差が生じた時に，回転数差に応じて差動を制限する．粘度の高いシリコンオイルの剪断抵抗を利用している．
The rotation induction type uses shearing resistance of the silicone oil with the high degree of . 粘 which restricts differential according to a number-of-rotations difference, when a difference arises in the number of rotations of a right-and-left ring (center DEFU if it becomes order axle).

回転感応式はスリップなど回転数に差が生じない限り差動制限を行わないので反応が遅いが，差動制限の利き具合は マイルドであり操縦性にあまり影響しないため運転感覚が安定しているのが長所である．しかし，伝達される駆動力の全体量とは無関係に制御されるので，路面のグリップ力に対して駆動力が圧倒的に大きいとき，片輪スリップを完全に解消することができないのが欠点．高性能 スポーツ車などには適していない．

■ 摩擦式 LSD
■ Friction type LSD

摩擦式 LSDは，駆動系に大きなトルク反力が生じた時に，歯車の抵抗やクラッチ板を利用して，トルクに応じた差動制限を行う． デフギアに大きなトルク反力を受けると差動制限するので，高速走行や スポーツドライビングのような恒常的に大負荷で走る場合は常に差動制限を行っており，この状態では差動制限する状態へすばやく反応することができる．しかしながら，雪道のように滑りやすい路面を小さなスロットル開度で走っている時などは，大きなトルク反力が発生しにくいため差動制限が発生しにくい．また，差動制限が強くなるとタイヤなどへの負荷が大きくなり燃費が低下するため，高速走行燃費では不利である．
Friction type LSD is . DEFU which performs differential restriction according to torque using the gear's resistance and driving clutch disc when big torque anti-power arises in a drive system. Since differential restriction will be carried out if big torque anti-power is received in a gear High-speed run Sport Carrying out only . which can react quickly to the state of always performing differential restriction when [ like driving ] running by large load constantly, and carrying out differential restriction in this state Since the load to a tire etc. will become large and fuel consumption will fall if . which differential restriction cannot generate easily, and differential restriction become strong, since it is hard to generate big torque anti-power while running the road surface on which it is easy to slide like a snowy road with the small degree of throttle 開, at high-speed run fuel consumption, it is disadvantageous .
■ 電子制御式
■ Electron Control type

エンジン出力や操舵角，車速，各駆動輪の回転数などを制御パラメーターにして差動制限を行い，状況に応じて回転感応やトルク感応，あるいはそれらを複合した差動制限の制御を可能にしたもの．電気経路や油圧経路の設定などに特別な設計が必要になるため高 コストだが，各車輪へのトルク伝達や 制動力の配分を微妙に コントロールする 電子制御スタビリティ コントロールや完全4チャンネル制御型ABSなどの他の 電子制御デバイスとの統合制御により高性能を実現できる可能性が期待されている．

【　ＬＳＤの基本講座　】
[Basic lecture of LSD ]

   1. はじめに
      Introduction
      機械式ＬＳＤと標準ＬＳＤ（ビスカス＆トルセン）とは構造的に全く異なるＬＳＤであるために、その特徴や性能も異なります。
      Since mechanical LSD and Standard LSD (screw dregs & TORUSEN) are LSD which is completely structurally different, the feature and performance also differ from each other.
      また、一般（オープン）デフとの比較ではトルク伝達上の性能は圧倒的な違いがあり、この違いは走行性、登坂性、走破性、等車の推進力に大きく影響します。
      Moreover, in comparison with general (open) DEFU, the performance on torque transfer has an overwhelming difference, and this difference influences greatly the impelling force of cars, such as roadability, the Tosaka nature, and running-the-whole-distance nature.

      より面白くロードスターをドライブする為に機械式ＬＳＤを推奨するもので、サーキットアタックはもとより、ドリフトや峠において、その効果を期待するものです。
      Recommending mechanical LSD, in order to drive a roadster more pleasantly, a circuit attack expects the effect at a drift or a peak from the first.
      代償としてチャタリング（バキバキ音）が発生しますが、基本的に出にくいイニシャル設定の他、オイルや添加剤などの工夫で低減させる事が出来ます。
      Although a CHATA ring (BAKIBAKI sound) is generated as compensation, it can be made to decrease with the device of oil besides an initial setup, an additive agent, etc. out of which it is hard to come fundamentally.
      ただし、あくまでもある程度のチャタリングは発生します。　ご理解の上、ご使用ください。
      However, a certain amount of CHATA ring is generated to the last. Please use it after an understanding.

      （ＬＳＤのメリット）
      (Merit of LSD)
      ・ 直進性向上　・加速性向上　・旋回性向上　・発進性向上　・走破性向上　・登坂性向上　・脱出性向上
      - On a going-straight disposition On - acceleration disposition On - revolution disposition On - start disposition On - running-the-whole-distance disposition On - Tosaka disposition On - escape disposition
   2. 一般（オープン）デフの構造
      Structure of general (open) DEFU
      デフの内部は以下の通りの構成となっています。
      The inside of DEFU has composition as follows.
          * サイドギヤ （２個）・・・左右駆動軸に接合
            Side gear (two pieces) ... It joins to a right-and-left drive axis.
          * ピニオンギヤ（４個）・・・サイドギヤと噛み合う
            PINIONGIYA (four pieces) ... It gears with a side gear.
          * ピニオン十字軸（１個）・・・デフケースに串刺しされる、ピニオンギヤの回転軸
            PINION cross axis (one piece) ... The axis of rotation of PINIONGIYA by which food on a skewer is carried out to DEFUKESU

      （直進状態）
      (Going-straight state)
      左右駆動軸に回転速度差は生じないので、左右サイドギヤは同一回転となる。
      Since a rotation speed difference is not produced on a right-and-left drive axis, a right-and-left side gear serves as the same rotation.
      従い、左右サイドギヤに挟まれるピニオンギヤも回転しない。
      It follows and PINIONGIYA inserted into a right-and-left side gear does not rotate, either.
      例：
      Example :
      デフ入力回転（ファイナル・ピニオンギヤ）　１００ｒｐｍの時
      DEFU input rotation (final PINIONGIYA) At the time of 100rpm
      右駆動輪　：　１００ｒｐｍ
      Right driving wheel : 100rpm
      左駆動輪　：　１００ｒｐｍ
      Left driving wheel : 100rpm


      （旋回状態）
      (Revolution state)
      ここでは右旋回を例としています。　
      Here, right revolution is made into the example.
      右駆動輪が内輪（遅い回転数）、左駆動輪が外輪（速い回転数）となりスムースな旋回となる。
      The inside (late number of rotations) and a left driving wheel turn into an outer wheel (quick number of rotations), and a right driving wheel serves as smooth revolution.
      実際の働きとしては、右駆動輪（内輪）は路面から車輪の回転を下げようとする抵抗を受けるので、デフ内部の動きは
      As actual work, since the resistance which is going to lower rotation of a wheel is received from a road surface, a right driving wheel (inside) is the motion inside DEFU.
          * 右サイドギヤはデフケースの回転速度より遅くなる。
            A right-hand side gear becomes later than the rotation speed of DEFUKESU.
          * ピニオンギヤが回転し、左サイドギヤに逆回転の回転速度を与える。
            PINIONGIYA rotates and the rotation speed of reverse rotation is given to a left-hand side gear.
          * 左サイドギヤはデフケースの回転速度より速くなる。
            A left-hand side gear becomes quicker than the rotation speed of DEFUKESU. 

      右で遅れた分を左に加速する働きを行い、左右駆動輪に回転速度差を与えながら駆動力を伝達するのです。
      The work which accelerates on the left the part which was overdue on the right is performed, and driving force is transmitted, giving a rotation speed difference to a right-and-left driving wheel.

      つまり、左右駆動輪の回転速度差は、抵抗の大きい側の車輪を基準に自動的にバランス調整され、スムースな旋回が出来る。　
      That is, balance adjustment is automatically carried out on the basis of the wheel of a side with strong resistance, and the rotation speed difference of a right-and-left driving wheel can perform smooth revolution.
      この動きをデフの"差動・（作動ではない）"と言います。
      This motion is called "differential - (it is not an operation)" of DEFU.

      例：
      Example :
      デフ入力回転（ファイナル・ピニオンギヤ）　１００ｒｐｍの時
      DEFU input rotation (final PINIONGIYA) At the time of 100rpm
      右駆動輪　：　　７０ｒｐｍ
      Right driving wheel : 70rpm
      左駆動輪　：　１３０ｒｐｍ
      Left driving wheel : 130rpm


      （オープンデフの欠点）
      (Fault of OPUNDEFU)
      例：　脱輪時にぬかるみから脱出ができない。
      Example: Escape is impossible from mud at the time of derailment.
      駆動輪の片輪が脱出域にぬかるみに入った場合、その車輪の抵抗はゼロになり、逆に接地している駆動輪には全抵抗が掛かっている事になる。
      When 片輪 of a driving wheel goes into an escape region in the mud, resistance of the wheel became zero and will have required all resistance for the driving wheel grounded conversely.
      このケースを前述の"差動"に当てはめると、
      If this case is applied to the above-mentioned "differential",
          * 接地側の駆動輪は静止（回転しない）
            The driving wheel by the side of grounding stands it still (it does not rotate).
          * ぬかるみ側の駆動輪は空転（デフケースの２倍の速度で回転する）
            The driving wheel by the side of mud is raced (it rotates by one twice the speed of DEFUKESU). 

      となります。つまり接地側の駆動輪にはトルクが伝達されず、車は動かないのです。
      It becomes. That is, torque is not transmitted to the driving wheel by the side of grounding, and a car does not move.




      例：ハードな旋回時に駆動力が得られない。
      Example: Driving force is not obtained at the time of hard revolution.
      モータースポーツ等でハードな旋回をする場合、作用する遠心力によって車体が傾き内輪が浮き気味となり、接地荷重（抵抗）が減少する事があります。
      When carrying out hard revolution by motor sports etc., by the centrifugal force which acts, the body may incline, the inside may float, it may become feeling, and grounding load (resistance) may decrease.
      この場合、先の脱輪状態と同様な状態になり、浮き気味の駆動輪に駆動力が集中することになります。
      In this case, it will be in a previous derailment state and the same state, and driving force will concentrate on the driving wheel liable to a float.
      その間一時的に車の推進力が得られず失速してしまいます。
      Temporarily, the impelling force of a car will not be obtained but will damp in the meantime.

      通常走行時でも、車輌状態（荷重変化やタイヤのグリップ）や路面状態（凹凸、抵抗、水溜り、砂などの摩擦係数の変化）の影響を受けて左右駆動輪の駆動力はめまぐるしく変化し、バランスを取っているのです。
      Usually, also in the time of a run, in response to the influence of a vehicle state (load change and grip of a tire), or a road surface state (change of friction coefficients, such as unevenness, resistance, a puddle, and sand), the driving force of a right-and-left driving wheel changed quickly, and maintains balance.
      つまり、少なからず駆動力の損失をしている事になります。
      That is, driving force will be lost not a little.

      この様なオープンデフの欠点「抵抗の小さい側の駆動輪に駆動力が集中してしまうこと」を補う為にＬＳＤは必要とされています。
      LSD is needed in order to compensate the fault "driving force concentrates on the driving wheel of a side with small resistance" of such OPUNDEFU.
      出来るだけ駆動力を無駄なく使い、推進力を高める装置なのです。
      It is equipment which uses driving force without futility as much as possible, and heightens impelling force.
   3. マルハ機械式（多板式）ＬＳＤの構造
      Structure of MARUHA mechanical (multi-board type) LSD
      デフケース内の構造は約２５点の部品で構成されています。
      The structure in DEFUKESU consists of parts of about 25 points.
          * サイドギヤ（２個）・・・左右駆動軸に接合する。
            Side gear (two pieces) ... It joins to a right-and-left drive axis.
          * ピニオンギヤ（４個）・・・サイドギヤと噛み合う。
            PINIONGIYA (four pieces) ... It gears with a side gear.
          * プレッシャーリング（２個）・・・デフケースに保持され、カム機構により左右にスライド力を発生させる。
            Pressure ring (two pieces) ... It is held at DEFUKESU and right and left are made to generate slide power according to a cam mechanism.
          * ピニオン十字軸（１個）・・・プレッシャーリングのカムに保持され、ピニオンギヤの回転軸となる。
            PINION cross axis (one piece) ... It is held at the cam of a pressure ring and becomes the axis of rotation of PINIONGIYA.
          * クラッチプレート（ドライブ）（４枚）・・・デフケースと一体回転する磨耗板。
            Clutch plate (drive) (four sheets) ... Wear board which DEFUKESU and really rotates.
          * クラッチプレート（ドリブン）（４枚）・・・サイドギヤと一体回転する磨耗板。
            Clutch plate (DORIBUN) (four sheets) ... Wear board which a side gear and really rotates.
          * サラバネ　（２個）・・・プラッチプレートを常時加圧しておくバネ。
            SARABANE (two pieces) ... Spring which always pressurizes the PURATCHI plate.
          * ワッシャー（２個）・・・サイドギヤのスラストを受け、摺動部焼き付きを防止する。
            Washer (two pieces) ... 摺動部 printing is prevented in response to the thrust of a side gear. 



      ピニオンはピニオン十字軸を回転軸として,サイドギヤはピニオンに噛み合うべくそれぞれ組み立てられます。
      PINION sets the axis of rotation as a PINION cross axis, and a side gear is assembled, respectively so that it may gear to PINION.
      デフケース内側にはキー勘合し、軸方向に可動なプレッシャーリングがあり、プレッシャーリングの片面には十文字にＶ字状の溝があります。
      Key 勘合 is carried out at a DEFUKESU inner side, there is a movable pressure ring in the direction of an axis, and there is a V character-like slot in one side of a pressure ring crosswise.
      左右プレッシャーリングのＶ字溝でピニオン十字軸を挟みこむ。
      It is crowded with the V character slot of a right-and-left pressure ring on both sides of a PINION cross axis.
      従って、ピニオン十字軸はフロート状態にあり、デフケースとは直結していません。
      Therefore, a PINION cross axis is in a float state, and is not directly linked with DEFUKESU.

      ＊オープンデフでは、ピニオン十字軸はデフケースに串刺し状態（直結）である。
      * In OPUNDEFU, a PINION cross axis is in a food-on-a-skewer state (direct connection) at DEFUKESU.

      左右プレッシャーリングとデフケース内側面の間にはデフケースの内側にキー勘合するクラッチプレート（ドライブ・外ツメ）と、左右サイドギヤにキー勘合するクラッチプレート（ドリブン・内ツメ）が交互に配列配置されています。
      Between the right-and-left pressure ring and the DEFUKESU inner side side, arrangement arrangement of the clutch plate (a drive and outside TSUME) which carries out key 勘合 inside DEFUKESU, and the clutch plate (DORIBUN and inside TSUME) which carries out key 勘合 at a right-and-left side gear is carried out by turns.




      （ＬＳＤの起動）
      (Starting of LSD)
      アクセルＯＮで駆動力がＬＳＤに入力されると、デフケースと一体回転するプレッシャーリングは回転しようとします。一方、車軸は慣性力により現状維持し続けようとします。
      If driving force is inputted into LSD with Accelerator ON, the pressure ring which DEFUKESU and really rotates tends to rotate. On the other hand, an axle tends to continue carrying out present condition maintenance according to inertia power.
      この両方の力が衝突するポイントは、フローとしているピニオン十字軸とプレッシャーリングのＶ字溝の部分です。
      The point with which the power of these both collides is the portion of the V character slot of a PINION cross axis and a pressure ring made into the flow.

      当初、ピニオン十字軸はＶ字溝の中央に納まっていますが、駆動力が作用するＶ字溝と慣性力が作用するピニオン十字字軸との間にはズレが生じ、クサビ効果によってオピニオン十字軸が左右プレッシャーリング（Ｖ字溝）を押し広げます。コレを「カム作用」と言います。
      Although the PINION cross axis is settled in the center of a V character slot at the beginning, gap arises between the V character slot on which driving force acts, and PINION cross 字軸 on which inertia power acts, and an opinion cross axis extends a right-and-left pressure ring (V character slot) according to the KUSABI effect. KORE is called "cam action."


      コレによって、交互に配列されたクラッチプレート（ドリブン・ドリブン）が押し付けられ、デフケースとサイドギヤがクラッチプレートを介してつながる。このクラッチプレートは左右ともに設けられるので、結果的に左右サイドギヤが繋がっている事になります。
      The clutch plate (DORIBUN DORIBUN) arranged by turns is pushed by KORE, and DEFUKESU and a side gear are connected through a clutch plate by it. Since, as for this clutch plate, right and left are prepared, the right-and-left side gear will be connected as a result.

      左右サイドギヤはクラッチプレートを介して繋がっているので、左右サイドギヤ結合率（ロック率）はカム作用に応じて変動する。カム作用は駆動力と慣性力のバランスによるものであり、コレが「トルク感応型」と呼ばれる所以である。
      Since the right-and-left side gear is connected through the clutch plate, the rate of right-and-left side gear combination (rate of Locke) is changed according to a cam action. A cam action is based on the balance of driving force and inertia power, and is a reason to which KORE is called a "torque induction type."
      決してメカニカルロック（ロック率１００％）ではありません。
      It is never a MEKANIKARU lock (100% of rates of a lock).

      アクセルＯＦＦまたはブレーキングで制動力がＬＳＤに入力されると、カム作用は逆方向に作用する。　
      If braking power is inputted into LSD by Accelerator OFF or breaking, a cam action will act on an opposite direction.
      コレは、車軸が制動力、デフケース側が慣性力となるので力のバランスがアクセルＯＮ時とは逆になるからです。
      Since, as for KORE, a braking power and DEFUKESU side serves as [ an axle ] inertia power, the balance of power is because it becomes reverse at the time of Accelerator ON.

      カム作用はＶ字溝角度によってその特性を任意に設定する事ができます。
      A cam action can set up the characteristic arbitrarily with a V character slot angle.
          * Ｖ字溝角度を開き方向に設定した時
            When a V character slot angle is set up in the difference direction
            プレッシャーリングの押し広げ力は大きく作用する。ＬＳＤの効きは強い。
            A pressure ring extends and power acts greatly. Effectiveness of LSD is strong.
          * Ｖ字溝角度を閉じ方向に設定した時
            When a V character slot angle is closed and it is set as a direction
            プレッシャーリングの押し広げ力は小さく作用する。ＬＳＤの効きは弱い。
            A pressure ring extends and power acts small. Effectiveness of LSD is weak. 

      ＬＳＤはカム作用による特性の違いから、大きく３分類される。
      Three 分類s of LSD are enlarged from the difference in the characteristic by cam action.
         1. Ｖ字溝角度が左右対象であるもの・・・「２ＷＡＹカムタイプ」と呼ぶ。
            That whose V character slot angle is a candidate for right and left ... It is called "2WAY cam type."
            アクセルＯＮ／ＯＦＦ両方でＬＳＤが効く仕様。
            Specification which is effective by both accelerator ON/OFF.
         2. Ｖ字溝角度が左右非対称であるもの・・・「１．５ＷＡＹカムタイプ」と呼ぶ。
            a V character slot angle -- right and left -- an asymmetrical thing ... it is called a "1.5WAY cam type."
            アクセルＯＦＦ時のＬＳＤの効きが弱い仕様。
            Specification with weak effectiveness of LSD at the time of Accelerator OFF.
         3. 時溝角度の一方が垂直であるもの・・・「１ＷＡＹカムタイプ」と呼ぶ。
            a time -- what has perpendicular one side of a slot angle ... it is called "1WAY cam type."
            アクセルＯＦＦ時のＬＳＤの効きがゼロである仕様。
            Specification whose effectiveness of LSD at the time of Accelerator OFF is zero. 

      （イニシャルトルク）
      (Initial torque)
      サラバネによって多板クラッチに常時圧力を掛けています。
      Pressure is always put on the multiplate clutch by SARABANE.
      この圧力による多板クラッチの摩擦トルクを「イニシャルトルク」と言います。
      The friction torque of the multiplate clutch by this pressure is called "initial torque."

      イニシャルトルクには２つの役割があります。
      There are two roles in initial torque.
         1. ある程度以下のカム作用を制御する。→微笑駆動力変化によるハンチング防止。
            The following cam actions are controlled to some extent. Hunching prevention by -> smile driving force change.
         2. 差動・空転時のカム作用を助長する。→ピックアップの向上。
            The cam action at the time of differential and idling is promoted. Improvement in -> pickup. 

      また、イニシャルトルクを高くすると、常時ＬＳＤが効き放し（トルク感応でない）になり、旋回性の悪化を招く欠点があります。
      Moreover, if initial torque is made high, it becomes LSD being always effective and releasing (it not being torque induction), and there is a fault which causes aggravation of revolution nature.

      これら相反する役割と欠点を調和するには、車軸のスペック（出力、運動性能）を念頭に,用途に合わせた設計及び調整が必要になります。
      In order to harmonize these 相反する role and a fault, the design and adjustment which were united with the use are needed bearing in mind the spec. (an output, motile ability) of an axle.

      例：
      Example :
      レース、競技・・・・イニシャルトルク高め→ＬＳＤ効き優先
      A race, game .... Initial torque higher ->LSD effectiveness priority
      ストリート・・・・　イニシャルトルク低め→トルク感応優先
      Street .... Priority is ->-torque-induction-given in slight initial torque lowness.

I might have to try and contact Mazda Japan somehow?? and find out what they can tell me about their LZ box with optional LSD, I may need to translate English to Japanese though if I can find a way.

[twilightprotege]

someone there will know engrish. most ppl in japan know some sort of engrish

[Nate]

i know some sort of japanese. Krista knows a fair amount ... but car terms she probably wouldnt know

[Rupewrecht]

do you know what it's out of?

i'd say MX6, as i have a vague memory that some JDM MX6s came with LSD

ask on mx6.com

[boostedbatman]

Its from the Lantis Type R. The 93/08-96/06 had LSD as an option and the 96/07-97/12 had it standard according to http://www.alljapanesecars.com/viewc...=1994&mc=CBAEP
So those with the v6 should be able to get the later model box and get it as standard...........yay
The other prob with www.mazda.co.jp is that it doesnt translate to well so I had to sit here for a few hours translating every part bit by bit and in the end I think I got it right and then tyed all the parts to the enquiry in english then translated to Japanese and then sent it so I hope they understand it and get back too me

[CRA23]

i just did a quick search and you are right about the lsd been std from after 96/7. several sites also said it was option till 96/7 then std from then on.

this means all i have to do is find a 96/7 on lantis gearbox and i will have a manual and a lsd

[boostedbatman]

I bet you're smiling right now at the idea of free LSD,for the beautiful thing is when you track down the box just about all wreckers have no idea of its existance.
Their loss Timmys gain

[boostedbatman]

I am currently in email conversation with some one from Mazda Japan and hopefully soon I will be able to get the technical specifics that we are chasing . I have also asked whether they have any diagrams/ data/manuals for this part and have offered to purchase them. I am playing the lost puppy with a nice woman there and hopefully it has been met sympathetically, and that our help is not far away

[Rupewrecht]

well there you go - didn't know about the V6 LSD!

should fit in early BA 1.8s too then (diff, not box)

[Mr MX6]

my one is from a mazda speed lantis.. second hand from Japan..
you can get them brad new from Crocksport http://www.corksport.com/ bit priceyor this one on mx6.com http://www.mx6.com/forums/showthread.php?t=136325

[boostedbatman]

Its been a while since youve been on here Paul
BTW have you had your LSD strengthened?
I will get mine done in the coming months

[chicaboo]

Any chance there was a 1.8 G series gearbox with LSD that could be coerced into fitting in my car?

Gav.

[Mr MX6]

stock as a rock no cryogenic crap lol.. I think better idea is to strengthen the housing I have trashed 2 housings .. Basically the drive pushes the end bearing thru the divining wall between the 5th gear and the rest of the box..
But I have done that either... lol I jut keep replacing them and vowing not to launch hard any more .. lol
and in one of the mx6s I have a phantom grip.. not so good (by a long shot)
