Pressure source for electro-fluidic actuating or supply device of motor vehicle drive train, has housing that is provided with two housing parts, where housing parts are connected to each other through joint

摘要

The pressure source has a housing (80) that is provided with two housing parts (130,134), where the housing parts are connected to each other through a joint. A fluid pump (42A) is arranged on the former housing portion adjacent to the joint, where the fluid pump is driven by an electric motor (46A). The fluid pump is a rotary piston pump that is provided with a drive shaft, where the drive shaft is driven through a motor shaft (142) of the electric motor. The drive shaft and the motor shaft are arranged coaxially to each other. The electric motor is fixed in the former housing part. An independent claim is provided for a device for electro-fluidic supply or operation of a component of a drive train, such as a friction clutch or a gearbox.
