Embodiment Construction

[0052] exist figure 1 shows an electrical machine assembly 2 for an actuator 4 of a motor vehicle transmission 6 , in particular a direct-shift transmission. The electromechanical assembly 2 , which is also referred to below as the actuator 4 of the transmission actuator, comprises an elongated electronics unit 8 with a coupling socket 10 projecting on the narrow side, and an electric motor 12 fastened to the electronics unit 8 .

[0053] The electronics unit 8 comprises a first housing shell in the form of a motor base 14 , a second housing shell in the form of a cooling cover 16 and an electronics base sandwiched between the motor base 14 and the cooling cover 16 18. The connection plug 10 is here integrally formed on the end side of the electronics mount 18 . By means of the connection connector 10 , the converter circuit 20 of the electronics base 18 can be electrically conductively connected to a not further shown vehicle electronics or to a vehicle branch circuit in or...

Abstract

The invention relates to a motor assembly (2) having a motor (12) comprising a motor housing (24) and an electronics unit (8) comprising a motor base (14) on which is fastened an electrical A first housing cover of the machine housing (24), a second housing cover designed as a cooling cover (16) and an electronics base (18), which are sandwiched between the cooling cover and the motor base, The electronics base has on the side of the cooling cover a first sealing device (70) surrounding the circumference, which seals a first contact edge (72) formed between the electronics base and the cooling cover, the electronics base On the side of the motor base there is a second circumferential sealing device (74) which seals a second contact edge (76) formed between the electronics base and the motor base. The invention also relates to an actuator for a motor vehicle comprising the aforementioned electric machine assembly and a motor vehicle transmission (6) having the aforementioned actuator.

Description

technical field [0001] The invention relates to an electric machine assembly having an electric motor with an electric machine housing and an electronic unit. The invention further relates to an actuator for a motor vehicle, in particular a transmission actuator, having such an electric machine assembly, and to a motor vehicle transmission provided with such an actuator. Background technique [0002] An electric motor is known from WO 2013 / 037454 A2, which can be a component of an actuator for a motor vehicle transmission, in particular a direct-shift transmission (DSG). In the case of hydraulic actuators, an electric motor can be used to drive a hydraulic pump. [0003] Known electric motors have for this purpose a cylindrical motor or stator housing in which the stator assembly with the rotating field winding is mounted fixed relative to the housing and the rotor, together with the rotor shaft fixed relative to the rotor, can be The rotational movement is supported in th...
