Embodiment Construction

[0019] exist figure 1 shows the main components of a transmission drive unit 10 as it is used in particular in the motor vehicle industry as part of a window regulator drive. The transmission drive unit 10 is used for lowering or raising the window panes (not shown in the figure).

[0020] The transmission drive unit 10 has a housing 11 made of several parts, which is in figure 1 Only the lower part 12 of the housing can be seen. exist image 3 The housing upper part 24 shown in is in this case connected to the housing lower part 12 , in particular by means of a screw. Furthermore, a connection plug 13 is attached to the housing 11 for controlling and supplying a drive motor 14 designed as an electric motor with voltage. The drive motor 14 has a image 3 The drive shaft 15 which can be seen in the figure has a toothing 16 in the form of a worm gear on its end facing away from the drive motor 14 . The toothing 16 meshes with an external toothing 19 formed on the drive gea...

Abstract

The unit has a drive power window with an output element e.g. output wheel (22), projecting from a housing and forming an interface for a mobile functional element and having a first connection geometry of form (25) for connection to the functional element. The first connection geometry of form has maximum extension on the output element at an interface with respect to a longitudinal axis of the output element. The first connection geometry of form has another maximum extension greater than the former extension. The output element is made of plastic. An independent claim is also included for a window regulator assembly comprising a drive and transmission unit.

Description

technical field [0001] The invention relates to a transmission drive unit. The invention also relates to a functional element and an arrangement comprising a transmission drive unit and a functional element. Background technique [0002] Such a transmission drive unit is already known from the applicant's DE 10 2005 012 938 A1. The known transmission drive unit used as a component of the window regulator drive has an electric drive motor, which interacts indirectly via a drive shaft with helical teeth with an output gear made of plastic, the output gear of which is driven by the The protruding part of the housing of the drive unit acts as an output shaft. The output gear has toothing on its outer circumference, which interacts positively with a functional element. In the case of a window regulator drive, the functional element is usually a cable drum made of plastic, which has internal teeth cooperating with external toothing of the output gear on the inner wall of a bore...
