Embodiment Construction

[0034] figure 1 A motor vehicle actuating drive 2 is shown, which comprises a transmission unit 6 with a transmission housing 4 and a motor unit 10 with a motor housing 8 . In the present embodiment, the motor vehicle actuating drive 2 is, for example, a window lift drive, a seat adjustment drive or a sunroof drive.

[0035] The motor housing 8 is, for example, a metal pole pot that is deep-drawn from sheet material. feels like figure 2 and image 3 As can be seen in , the motor unit 10 arranged inside the motor housing 8 comprises an electric motor 12 having a motor shaft 16 carrying a rotor or mover 14 , which is rotatably supported on a rotor-side spherical bearing 18 and in the plain bearing or sintered bearing (Sinterlager) 20 on the transmission side. Permanent magnets 22 held in a fixed position in motor housing 8 form the stator of electric motor 12 .

[0036] Between the rotor 14 and the sliding bearing 20 , a commutator with a commutator shaft (not shown in det...

Abstract

The invention relates to a method for manufacturing a motor vehicle servo drive. The motor vehicle servo drive comprises a transmission gear unit (6) having a transmission gear housing (4), and a motor unit (10) having a motor housing (8), wherein the motor housing (8) is provided with a rough contact surface (48), wherein axial clearance compensation is executed between the motor unit (10) and the transmission gear unit (6), wherein the contact surface (48) of the transmission gear housing is at least partly melted, wherein the contact surface (48) of the transmission gear housing is melted into the contact surface (50) of the motor housing, and wherein the contact surface (48) of the transmission gear housing is cooled.

Description

[0001] This application is a divisional application of an invention patent application with the filing date of July 21, 2016, the title of the invention is "Method for Manufacturing a Motor Vehicle Servo Drive" and the application number is 201610579805.5. technical field [0002] The invention relates to a method for producing a motor vehicle actuating drive comprising a gear unit with a gear housing and having a motor unit with a motor housing. Furthermore, the invention relates to a motor vehicle actuating drive produced according to this method. Background technique [0003] Motor vehicle actuating drives are used, for example, as window lift drives or as drives for actuating sunroofs. A motor vehicle actuating drive typically has a motor unit and a transmission unit. The gear unit conventionally comprises a worm gear arranged in a gear housing made of plastic, which has a worm wheel and has a transmission shaft realized as a worm shaft. The motor unit expediently has ...
