1997 TOYOTA SUPRA torque

27 SUPRAÐNEW FEATURES
Construction
The helical gear type torque±sensing LSD consists of a differential case, 9 planet gears, 2 side gears and 4 thrust
washers.
Planet gears mesh with one another as a pair, and each gear of the pair meshes with the side gear on its right or left
side.
The planet gears are supported by the hole that is provided in the differential case. They are constructed so that they
revolve while rotating over the side gear.
Operation
1) Straight±Ahead Operation
Since side gears (left and right) and planet gears are rotating together with the differential case as a unit when the
vehicle is running straight±forward, the driving force is transmitted from the ring gear to the differential case, planet
gears and side gears.

28SUPRAÐNEW FEATURES
2) Cornering
Supposing that the differential case is not moving, rotating the left side gear counterclockwise, causes planet gear
A (which meshes with the left side gear) to rotate clockwise.
Furthermore, planet gear B, which is paired with planet gear A, rotates counterclockwise, causing the right side gear
(which meshes with planet gear B) to rotate clockwise.
Therefore the left and right side gears rotate in the opposite direction each other, thus accomplishing a motion
differential.
3) Limited Slip Differential Operation
Limited slip is accomplished primarily b the friction that is generated between the planet gear's tooth tips and the
differential case's inner wall, and the friction that is generated between the side gear end face and the thrust washer.
The principle of limited slip enables the resultant reaction force F1 (which is created by the meshing reaction of the
planet gear and the side gear and the meshing reaction of the planet gears themselves) to push the planet gear in the
direction of the differential case in proportion to the input torque.
Due to the reaction force F1, the friction force u F2 (which is generated between the side gear end face and the thrust
washer) applies a force to cancel out the rotational difference between the side gears themselves as well as between
the side gear and the differential case.

OUTLINE NEW FEATURES
The Supra, which represents Toyota's advanced automotive technology, has earned a reputation as a truly luxurious
sports car. The following changes have been made for the 1997 model year.
1. Model Line±Up

The JZA80L±ALPVZA model has been discontinued.

The JZA80L±ALFVZA and JZA80L±AJFVZA models have been added.
2. Exterior Design

The multi±reflector type headlights are adopted.

The design of the turn signal light, front bumper and rear combination light has been changed.
3. Interior Equipment
The front seats have been changed from the separate±headrest type seats of the '96 model to the integrated headrest
type seats without changing their basic design.
4. 2JZ±GTE Engine
An aluminum radiator core is adopted for weight reduction.
5. Differential

A differential gear ratio has been changed on he 2JZ±GE engine model.

A helical gear type torque±sensing LSD is available as an option on the 2JZ±GE engine model and 2JZ±GTE engine
with automatic transmission model.
6. Drive Shaft
An outboard joint of drive shaft has been changed from cross±groove type CVJ (Constant±Velocity Joint) to Rzeppa
type CVJ on the 2JZ±GE engine model.
7. Brakes

A master cylinder diameter has been changed on the 2JZ±GTE engine model.

An ABS has been changed to the 2±position solenoid valve type actuator.
