Embodiment Construction

[0052] figure 1 An adjusting device 1 in the form of a double-beam rope window lifter is shown for adjusting the window glass 4 on the vehicle door. The adjusting device 1 in the form of a window lifter is provided on the assembly bracket 3. In order to provide a door module, the assembly bracket can be fixed in a modular manner with the adjusting device 1 provided on the assembly bracket. On the vehicle door, and in particular, it can be configured to separate the wet cavity N and the dry cavity T of the vehicle door in a moisture-proof and sealed manner in the state of being fixed on the vehicle door.

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

Abstract

The invention relates to a drive device for an adjusting device of a motor vehicle, having a housing or a housing section at least partially enclosing components of the drive device and an electromotor-driven drive shaft extending in the longitudinal direction, said The drive shaft is supported axially at least via the ends on the housing or housing section. It is proposed here that an active bearing element ( 5 ) is arranged on at least one end ( 200A) of the drive shaft ( 200 ) between the housing ( 21 ) or housing section and the drive shaft ( 200 ), so that The active bearing element is suitable for acting axially in the longitudinal direction (L) on the drive shaft ( 200 ) during operation of the drive device ( 2 ). In this way, a drive and a method for operating such a drive are provided, by means of which advantageous axial support of the drive shaft, self-locking of the motor and vibration damping can be achieved.

Description

Technical field [0001] The invention relates to a drive device for an adjusting device of a motor vehicle and a method for operating such a drive device. Background technique [0002] Such a drive device for an adjustment device of a motor vehicle includes a housing or housing section that at least partially surrounds the components of the drive device and an electric motor-driven drive shaft extending in the longitudinal direction, said drive shaft at least via an end The section is supported axially on the housing or housing section. Such a drive device can be used, for example, in the form of a window lifter on a vehicle door or also in the form of an adjustment device, for example, a seat adjuster or a roof manipulator. [0003] In such a drive device known from EP 1 436 880 B1 which is configured as a drive mechanism for a window lifter, the drive shaft is axially supported on the housing of the drive device. In this case, the support can be achieved, for example, by placing...
