traction.In hard acceleration, PSK transferred up to 80% torque to the rear wheels. Why? Because hard acceleration leads to rearward weight transfer, which reduces traction at front wheels and increases traction at http://www.obdchina.com/for-toyota-obd-4d-key-programmer-p-1226.html rear wheels. By transferring more torque to the rear wheels, the traction can be optimally used.On slippery road, 50 : 50 torque slit was used. In any time, computer determined the most suitable torque split ratio by analysing parameters such as throttle position, steering angle, g force and even turbo boost. Therefore PSK system provided near perfect traction that was not comparable by other 4WD systems.MechanismThe PSK 4WD system used auto diagnosis tool a multi-plate clutch instead of center differential to carry out the torque split. The clutch had 6 pairs of frictional plate, each pair was independently controlled by computer and actuated by hydraulic pressure. This was simply equal to 6 independent clutches.To make this system work, the front and rear drive-shafts must run at different speed in normal condition.
