Abstract

In a motor vehicle with one or several driven axles, as well as with corresponding equalizing gears and/or power dividers for the compensation of differences in the speeds of the wheels, the spinning of wheels and/or axles is avoided through the use of braking devices for the braking of individual wheels, in conjunction with locking devices for the above-mentioned equalizing gears and/or power dividers. Upon reaching a predetermined speed difference value between the drive axles, a reduction of this speed difference is first brought about by actuation of the corresponding braking devices. When a predetermined approach tendency of the wheel speeds to each other is reached, a synchronization of the wheels is obtained by actuating the appropriate locking device. In this manner, a synchronization of rotating parts is achieved during any speed behavior of the rotating parts, without damage to parts of the motor vehicle.
