ABSTRACT:
Two sets of independently rotatable gear wheels are interconnected between the differential gear coupled to the motor and the two respective reduction drives coupled to the gear wheel rack and pinion drive and adhesion wheel drive. The sets of gear wheels are connected at different drive positions to the differential gear to permit a reduction in stresses in the gear wheel drive and associated rack. A blocking device which is used to block the drive of the gear wheel when needed also allows the adhesion wheel drive to be driven at a higher rate. A clutch is used to vary the drive between the gear wheel and adhesion wheel drive.
