The invention relates to a device for camber and/or track adjustment of a vehicle wheel (20), comprising a wheel mounting (12) having an actuating element (26, 28) which is rotatable about an axis of rotation and is connected between the mounting part (24) on the wheel side which receives the vehicle wheel and the guide part (22) on the axle side which is connected to a wheel suspension, said actuating element being adjustable by means of a drive rotating unit (38) for adjustment of the camber and/or the track of the vehicle wheel (20), wherein a locking element (52) is connected in the drive path between the drive rotating unit (38) and the actuating element (26, 28), and in a release position (I) said locking element frees the drive path for transmission of a driving torque (MA) from the drive rotating unit (38) to the actuating element (26, 28), and in a locking position (II) said locking element produces a locking torque which counteracts a reaction torque (MR) from the actuating element (26, 28) directed onto the drive rotating unit (38). According to the invention the locking element (52) is a double-action freewheel, which opens in the event of a driving torque (MA) of the rotary drive unit (38) and closes in the event of a reaction torque (MR) of the actuating element (26, 28). |
