Drive arrangement for an adjusting element of a motor vehicle

摘要

The invention relates to a drive arrangement for an adjusting element of a motor vehicle, a clutch arrangement which is connected into the drive train with a drive connection and a driven connection, the clutch arrangement at any rate forwarding a movement which is introduced on the drive side to the driven connection and having a braking arrangement for braking a movement which is introduced on the output side. The braking arrangement has a braking element which can be adjusted counter to a braking force, in that, between the output connection and the braking element, the clutch arrangement has a freewheel arrangement comprising at least one freewheel pair of clamping body freewheels which operate in opposite directions, in that a movement which is introduced on the output side always brings about the blocking of at least one clamping body freewheel and is correspondingly braked via the braking arrangement.

主权项

1. A drive arrangement for an adjusting element of a motor vehicle, comprising:
a clutch arrangement which is connected into a drive train, wherein the drive train comprises a drive side and an output side; a drive connection; a driven connection; and a braking arrangement; wherein a movement introduced on the drive side is forwarded by the clutch arrangement to the driven connection; wherein a movement introduced on the output side is braked by the braking arrangement; wherein the braking arrangement has a braking element which can be adjusted counter to a braking force between the driven connection and the braking element; wherein the clutch arrangement has a freewheel arrangement comprising at least one freewheel pair of clamping body freewheels wherein a clamping body freewheel in the at least one pair of clamping body freewheels operates in an opposite from a second clamping body freewheel in the at least one pair of clamping body freewheels; wherein the movement introduced on the output side always brings about blocking of at least one of the clamping body freewheels in the at least one pair of clamping body freewheels and is correspondingly braked via the braking arrangement, and wherein the movement which is introduced on the drive side always brings about the release of the clamping body freewheels in the at least one pair of clamping body freewheels.
