Abstract
A differential drive that includes a rotatably driven differential housing supported in a housing. The differential drive further includes a differential gear set arranged and supported in the differential housing. The differential drive also includes a torque distribution device adjacent to a differential gear set. The torque distribution device connects a differential side shaft gear with one side shaft. The torque distribution device is arranged to control the torque between a front axle and a rear axle of a motor vehicle.
Claims4
A differential drive for use on a vehicle, said drive including:
- a rotatably driven differential housing supported in a housing;
- a differential gear set arranged and supported in said differential housing;
- and
- a torque distribution device adjacent to said differential gear set, said torque distribution device connects one of the differential side shaft gears with a side shaft, said torque distribution device arranged to control torque between a front axle and a rear axle of the vehicle wherein said torque distribution device includes a clutch pack, a pin for engaging said clutch pack, a ball ramp mechanism which engages said pin opposite said clutch pack, and an electric motor which engages said ball ramp mechanism.
A differential drive for use on a vehicle, said drive including:
- a rotatably driven differential housing supported in a housing;
- a differential gear set arranged and supported in said differential housing;
- a torque distribution device adjacent to said differential gear set, said torque distribution device connects one of the differential side shaft gears with a side shaft, said torque distribution device arranged to control torque between a front axle and a rear axle of the vehicle;
- and a plurality of friction plates adjoining said side shaft gear and said differential housing to create a side to side locking effect wherein the number of said friction plates is used to determine a locking ratio between said front axle and said rear axle and side shaft to side shaft.
