Embodiment Construction

[0021] exist figure 1 The drive unit 10 shown in is provided as an actuating drive in a motor vehicle, in particular for adjusting elements not shown, such as window panes, seats, sunroof, etc. For this purpose, the drive unit 10 , which is designed as a transmission drive unit 10 , comprises a first housing part 11 , preferably made of plastic, designed as an injection molded part, which is designed in the form of a transmission housing 12 . The transmission housing 12 is connected to a second housing part 13 which serves as a motor housing and is designed in the form of a so-called pole pot 14 . The second housing part 13 is produced from sheet metal and is designed as a deep-drawn part. Fastened between the two housing parts 11 , 13 in a coupling region 15 on the end face of the transmission housing 12 via a surrounding ring formed on the second housing part 13 housing flange 16. For a releasable connection between the two housing parts 11 , 13 , a total of four fastenin...

Abstract

The invention relates to a method for producing driving unit for motor vehicle servo driving device and the driving unit. The driving unit comprises a first housing part connected with a second housing part in a linkage area. In order to center the housing parts, the first housing parts is provided with at least two centering pins cooperating with centering openings arranged in the second housing parts. A first clearance fit is arranged in one of the centering pin and the corresponding centering opening. During determination of dimensional tolerance set of distances between the centering openings and the centering pins, a reference point related to one of the centering pins and the corresponding centering opening is selected, and the dimensional tolerance set is stared from the reference point, so least-possible second clearance fits or transition fits in manufacturing technology is configured between the centering pins and the corresponding centering openings, and the first clearance fit is configured between at least one other centering pin and the corresponding centering opening.

Description

technical field [0001] The invention relates to a method for producing a drive unit for an actuating drive in a motor vehicle according to the preamble of claim 1 . Furthermore, the invention includes a drive unit produced according to the method according to the invention. Background technique [0002] A method for producing a drive unit according to the preamble of claim 1 is known from DE 10 260 104 A1 of the applicant. This method is used when assembling a transmission housing and a motor housing designed as a pole pot, both of which are part of a drive unit, for example a window lift drive or the like. What is important here is that the drive unit comprises an armature shaft mounted in several bearing devices, wherein one of the bearing devices is arranged in the motor housing and the other bearing device is arranged in the transmission housing body. In order to avoid alignment errors between the bearing devices that would lead to increased friction and thus loss of ...
