2. TORQUE STEER

Torque steer is a condition in which a vehicle pulls to either side because of an inequality of traction

between the left and right driving wheels when a large torque is applied to the front wheel of a FWD or

4WD.

Especially for a FWD vehicle, this mechanical condition can cause the steering effect because of the

output torque (rotational force) produced by the gyroscope.

This rotational force is due to the difference in distance between the left/right front wheels and the

transaxle which leads to the change of the shaft bending angle.

To prevent this, the intermediate shaft, called Intermediate shaft, is employed on each side so that the

bending angle and the length are kept constant.

A gyroscope is a device for measuring or maintaining orientation, based on the principles of angular

momentum. In essence, a mechanical gyroscope is a spinning wheel or disk whose axle is free to

take any orientation. Although this orientation does not remain fixed, it changes in response to an

external torque much less and in a different direction than it would without the large angular

momentum associated with the disk's high rate of spin and moment of inertia. Since external torque

is minimized by mounting the device in gimbals, its orientation remains nearly fixed, regardless of

any motion of the platform on which it is mounted.

3. REAR AXLE

The rear axle installed in this car is a removable axle, called IRDA (Independent Rear Differential Axle).

The rear differential carrier is installed directly on the sub frame,

and there is an independent suspension that allows each wheel on the same axle to move vertically and

independently of each other with the universal joint and the slip joint.
