Abstract
An electric drive for a vehicle includes at least one electric machine, a differential, and two brakes installed in a common housing. The brakes are disc brakes with a first and a second disc pack which are arranged on the side output shafts of the differential so as to rotate therewith and connect the side output shafts to a brake housing in the event of an actuation to apply a braking torque to the vehicle.
Claims19
An electric drive for a vehicle, the electric drive comprising:
- at least one electric machine, a differential, and two brakes installed in a common housing,
- wherein the brakes are multi-disc brakes with a first and a second disc carrier having associated first and second sets of discs, and
- wherein the brakes include a brake housing,
- wherein the first and second disc carriers are arranged in co-rotating fashion on the side driven shafts of the differential and, when actuated, connect the side driven shafts the a brake housing to apply a brake torque to the vehicle.
The electric drive for a vehicle, wherein, when actuated, an actuating force is applied to the first set of discs via an axially displaceably mounted actuating piston, and
- wherein the actuating piston is supported indirectly or directly on the second disc carrier via an axial bearing with a spring disposed between the second disc carrier and the actuating piston.
