  • Differential gear and control system for motor vehicles having a single driven axle and at least one undriven axle
    Patent number: 4979931
    Abstract: A differential gear and control system for motor vehicles having a single driven axle and at least one undriven axle comprises a differential gear and a differential lock, which is adapted to be controlled in dependence on the speed of travel of the vehicle. In order to increase the traction when the vehicle is started whereas the handling of the vehicle should not adversely be affected by a locking of the differential gear, the differential lock is adapted to be controlled so that it exerts on the differential gear a restraining torque which decreases as the speed of travel of the vehicle increases from zero to a predetermined speed of travel.
