A device lor the transfer of a torque from an output shaft of a drive mounted on the body of a motor vehicle with a rotational axis of the output shaft and a hinge axis arranged flush with one another. The device includes a drive lever rotationaily connected to the output shaft of the drive, a connecting member on the drive lever extending from a connecting region of the drive lever. The connecting member includes a sliding block and an adapter part that is connected to a first half of a hinge and is provided with a journal. The journal rotates directly in, but independently of, the sliding block.

Device for the transfer of a torque

An electromagnetic frictionally engaged clutch provided with a rotor part including a friction lining. An electrical coil and a first permanent magnet are arranged on the rotor part. The clutch also includes an armature disk which is connected to a second shaft and can be displaced in a rotationally fixed manner, but axially from a coupled end position to an uncoupled end position. The coil of the clutch is enabled to be current-free both in the coupled state and in the uncoupled state. To this end, a second permanent magnet is provided for exerting an axial force opposing the magnetic force of the first permanent magnet on the armature disk.

Electromagnetic friction engaged clutch, method for the operation thereof, and use thereof in a drive train for automatically actuating a vehicle door or a vehicle flap

An electromagnetic frictionally engaged clutch for arranging inside a drive train connecting a drive motor and a vehicle door or flap. The arrangement ensures that the vehicle door is securely held in each intermediate position, when the clutch is in an idle state, while maintaining the possibility of a manual emergency actuation of the vehicle door. The rotor includes at least one permanent magnet in addition to the electric coil, such that when a current does not pass through the coil, the armature disk is pressed against the friction lining of the rotor, with a force which is strong enough for the vehicle door or vehicle flap to securely remain in position occupied when the clutch is an idle state, and for the friction engagement between the armature disk and the friction lining to be overcome when the vehicle door or vehicle flap is subsequently manually actuated.

Electromagnetic frictionally engaged clutch and method for operating the same

The invention relates to a drive unit for automatically actuating a tailgate of a motor vehicle. Connecting the drive unit () to the vehicle door () or to a transmission device () by means of an output shaft (), said transmission device executing a pivoting movement which corresponds to the pivoting movement of the vehicle door (), and the drive unit () comprising at least one first sensor device (), which can be connected to an electronic evaluation device () and serves to detect the respective angular position of the vehicle door (). In order to make use of the advantages of an incrementally operating position measurement system of the vehicle door (), in which, recalibration is necessary not only after the end positions of the vehicle door () are reached following a power cut. The invention proposes dividing the entire pivot angle (&#xe0;) of the vehicle door () into at least three successive zones (pivot angle ranges) (&#xe0;-&#xe0;), it being possible to determine the individual pivot angle ranges (&#xe0;-&#xe0;) by means of a first sensor device (), which is suitable for detecting absolute values. The pivot angle of the vehicle door within the individual zones (&#xe0;-&#xe0;) is then detected with the aid of a second sensor device (), which comprises at least one incrementally operating measured value detector.

Drive for automatic operating of a vehicle door

A device having a drive () for pivoting a vehicle door or vehicle lid rotationally connected to a hinge bow () around a hinge axle (). In order to build the device () in a compact manner, wherein no special reinforcement of the hinges of the vehicle door or vehicle lid is required for utilization of the device () in compliance with regulations, a drive () is provided with a drive shaft () that is arranged in an extension of the hinge axle, the drive shaft () being connected to a bow-shaped drive lever () that is arranged parallel to the hinge bow () and that can be fixed to the hinge bow ().

Device for pivoting a vehicle door or a vehicle lid

The invention relates to an electromagnetic friction clutch for arrangement within a drive train connecting a drive motor and a vehicle door. The vehicle door is reliably held in any intermediate position when a clutch is disconnected. To preserve the ability to carry out a manual emergency actuation of the vehicle door, a compression spring is provided acting upon an armature disk of the clutch in the axial direction in such a way that, with the clutch in the disconnected state, the armature disk is pressed against the frictional lining of a rotor part with a force which is sufficient to ensure that the vehicle door remains reliably in position. During a subsequent manual actuation of the vehicle door, the frictional connection between armature disk and frictional lining can be overcome.
