Description

To be able to effectively use this, the exact backlash of teeth is assessed in a learning mode:

Initially the left drive motor will be switched on to accelerate the left vehicle wheel to nominal speed. As the right drive motor is switched off and thus running free, the left wheel is dragging the right wheel along. The flanks of a tooth in the differential touch each other on one side. Now the first limit position of gear play is measured by the reflector strips and the photo electric cells. The procedure is now reversed, the left drive motor of the roller set is switched off and the right vehicle wheel is accelerated to nominal speed. This time the left wheel is dragged along and in the differential the flanks of teeth touch each other on the opposite side. The second limit position of the gear play will now be measured. Out of the two measured limit positions the center of gear play is calculated. This "center of gear play" is used to control the rotation of wheels during the brake test.

During the brake test, both drive motors are accelerated to a speed where the "center of gear play" is reached. One vehicle wheel will rotate forward, the other in opposite direction. As soon as the nominal speed is reached by both wheels, and no brake torque is being transferred to the drive shaft, brake testing may be started.

As with standard vehicles the drive motors will be switched off if excessive slip occurs.
