Abstract: A compact drive 1 has a housing 3 with two electric motors 5 and 31 therein and a transmission 9 provided with a differential 9 via which the electric motors are connected to output shafts 13. The transmission 9 further has a first switchable planetary gear set 17, which is present between the differential and the electric motors, and two second switchable planetary gear sets 23 located between the differential and the output shafts. One rotation body of these gear sets can be connected via a brake to the housing 3 and via a coupling to another of the rotation bodies. The brake and the clutch can only be operated simultaneously in such a way that when the brake is energized, the clutch is opened and vice versa. The output shafts, the electric motors and the transmission are concentric and the housing is cylindrical for a compact and robust construction.

Abstract: A transmission has a housing and two input/output shafts. Inside the housing is a planetary gear set with three rotatable members which are connected to the housing and the two input/output shafts. Inside the housing is a clutch which can connect two out of three of the rotatable members. When the clutch is closed the input/output shafts are connected together one to one. The pressure plate of the clutch is connected to a brake disc of a brake system that is connected to one of the rotatable members. When the brake system is closed the input/output shafts are connected via the planetary gear set. The transmission further includes a lever which can move the brake disc in axial direction and can thus open the clutch during operation.
