Description

IW4/IW7 WB/WBV

As described above, brake tests on 4-wheel drive vehicles are feasible if both wheels on the same axle counter-rotate at the same speed. As, in practice, the circumference of the left and right wheel is not exactly the same due to different tire tread depths and uneven tire pressure, the RPM of the two drive motors is normally different. Therefore the drive motors must control their speed in order to obtain the same RPM for both wheels.

Approximately the same speed of the roller set drive motors will be sufficient for a 4-wheel drive vehicle having a soft VISCO clutch in the drive shaft as no brake torque is transferred by the VISCO clutch when the drive shaft rotation is low. Therefore the speed control of the drive motors alone will be sufficient in this case.

Contrary to the above, when testing the brakes of 4-wheel drive vehicle having a hard VISCO clutch in the drive shaft both wheels on the same axle must rotate synchronously during the brake test, as the clutch viscosity is so low that even the slowest rotation of the drive shaft will transfer brake torque to the other wheels through the VISCO clutch.

c) Rigid drive shaft between the differentials

To perform a brake test on a 4-wheel drive vehicle having a rigid drive shaft, the wheel rotations must be exactly controlled in such a way that no brake torque can be transferred by the drive shaft.

Controlling the synchroneous rotation of the wheels

In order to control synchronous rotation of the wheels, reflector strips are fastened to the sides of the wheels which trigger a signal via two photo-electric cells, mounted on the side of the roller set.

On vehicles equipped with a rigid drive shaft or with a hard Visco clutch the wheels cannot be individually turned. If one vehicle wheel is turned forward in the roller set, the other wheel (on the same axle) will be turning backwards in a synchronous manner. If one wheel is turned slowly in forward or backward direction, one will note that the other wheel starts turning with a little delay. This slight delay in following the other wheel to turn is caused by the gear play (backslash of teeth) inside of the differential.

To perform a brake test on a 4-wheel drive vehicle having a rigid drive shaft, the wheel rotation must be controlled in such a way that no brake torque can be transferred by the drive shaft. This is achieved by staying within the gear play of the differential during the brake test. The differential will be in a "balance" state.
