Embodiment Construction

[0052] figure 1 The adjusting device 1 is shown in the form of a double-strand cable window lifter for adjusting a window pane 4 on a vehicle door. The adjusting device 1 in the form of a window regulator is arranged on an assembly carrier 3 which can be fastened in a modular manner together with the adjusting device 1 arranged on the assembly carrier in order to provide a door module. On the vehicle door, and in particular can be designed to separate the wet chamber N and the dry chamber T of the door in a moisture-tight manner in the fixed state on the vehicle door.

[0053] The adjusting device 1 in the form of a window regulator has a drive device 2 and two guide rails 11 , 12 extending in parallel. The drive device 2 is connected via a traction mechanism 130 in the form of a flexible cable guided at least partially in a Bowden cable 13 to drivers 14 , 15 guided on guide rails 11 , 12 , via which the The window pane 4 is supported in a sliding manner on guide rails 11 , ...

Abstract

The invention relates to a driving device for an adjusting device of a motor vehicle, comprising a housing or housing section that at least partially encloses components of the driving device and an electric-motor-driven drive shaft that extends in a longitudinal direction and that is axially supported on the housing or housing section at least by means of one end. According to the invention, an active bearing element (15) is arranged between the housing (21) or housing section and the drive shaft (200) at least one end (200A) of the drive shaft (200), said bearing element being suitable for acting on the drive shaft (200) axially in the longitudinal direction (L) during the operation of the driving device (2). In this way, a driving device and a method for operating such a driving device are provided, by means of which advantageous axial support of a drive shaft, motor self-locking, and vibration reduction can be achieved.

Description

technical field [0001] The invention relates to a drive for an adjusting device of a motor vehicle according to the preamble of claim 1 and to a method for operating such a drive. Background technique [0002] Such a drive for an adjusting device of a motor vehicle comprises a housing or a housing section at least partially enclosing components of the drive and an electromotor-driven drive shaft extending in the longitudinal direction, which is at least via an end The part is supported axially on the housing or housing section. Such a drive can be used, for example, in the context of an adjusting device in the form of a window regulator on a vehicle door or also in the form of, for example, a seat adjuster or a sliding roof operator. [0003] In the case of a drive of this type known from EP 1436880 B1, which is designed as a drive for a window regulator, the drive shaft is mounted axially on the housing of the drive. In this case, the bearing can be achieved, for example,...
