Problems solved by technology

The disadvantage here is the following: Some parts in the housing require a stable support, which creates problems when the relatively thin sheet thicknesses used
The known housings therefore have to be constructed from relatively thick sheet thicknesses, which are based on the loads of the most critical components, which has a detrimental effect not only on the housing weight but also on the material costs of the housing

Embodiment Construction

[0019] exist Figure 1 to Figure 3 A drive unit 10 according to the invention is shown in . The drive unit 10 is here in particular a component part of a wiper drive in a motor vehicle, wherein the wiper device, not shown otherwise, is at least are driven indirectly.

[0020] In the exemplary embodiment, the housing 11 is composed in particular of two housing half-shells 13 , 14 which are formed from sheet metal and produced by deep-drawing processes, only the details of which are shown in the drawings. One, the upper housing shell 13 is described.

[0021] as special basis figure 1 As a result, the two housing shells 13 and 14 have a region 15 for receiving a drive motor (not shown), in particular an electric motor. A further area 16 is connected to said area 15, said further area being used in particular to accommodate a transmission mechanism 17, which is in particular according to image 3 able to draw. The transmission 17 also includes a worm gear 18 , which is coup...

Abstract

The invention relates to a drive unit (10), comprising a housing (11) for a drive motor, which interacts with an element to be moved via a drive shaft (12), wherein the housing (11) comprises at least one housing shell (13, 14) made of sheet metal, in particular in a deep drawing method. According to the invention, a reinforcement element (25) is arranged in the interior (24) of the at least one housing shell (13, 14) and is connected to the at least one housing shell (13, 14).

Description

technical field [0001] The invention relates to a drive unit according to the preamble of claim 1 . Background technique [0002] Such a drive unit is already known and is used in particular as a component of a drive device. The electric motor used for the drive is accommodated in a housing which consists of two shell-shaped sheet metal shells produced in a deep-drawing process. The two plate shells are connected to each other. Such a housing has the advantage that it can be produced relatively simply and cost-effectively with a low weight. The disadvantage here is that some parts in the housing require a stable support, which creates problems when the relatively thin sheet metal thicknesses are used. The known housings therefore have to be constructed from relatively thick sheet thicknesses, wherein the thicknesses are based on the loads of the most critical components, which has a detrimental effect not only on the housing weight but also on the material costs of the ho...
