Embodiment Construction

[0052] figure 1 The drive device 3 is shown in perspective, which has an electric drive 34 and a permanent magnet brake 1 . Electric drive 34 is designed as an electric motor and has, in housing 340 , a stator that is fixed relative to housing 340 and a rotor that is rotatable relative to the stator. The rotor is rotatable about a longitudinal axis L and drives a driven shaft 341 on which is arranged a transmission 35 arranged downstream (cf. Figure 3A and 3B ) of the pinion element 342 to adjust the vehicle components.

[0053] as from figure 2 As can be seen in FIG. 2 , a drive device 3 of this type is used, for example, to adjust a rear lid 20 of a vehicle 2 . Drive unit 3 acts in a known manner between rear lid 20 and body 21 of vehicle 2 .

[0054] In principle, however, a drive device 3 of the type described here can also be used to adjust completely different types of vehicle components.

[0055] The drive device 3 can be designed, for example, as a screw drive,...

Abstract

A drive device (3) for displacing a vehicle part, in particular a tailgate (20), comprises an electric drive (34) for driving the vehicle part, the electric drive comprising a drive shaft (341) for transferring a displacement force to the vehicle part, and a first braking device (1), operatively connected to the drive shaft (341), which has a permanent magnet element (12, 14) and is designed to provide a braking force for arresting the vehicle part in a position currently adopted. In addition, a second braking device (4) is provided which is designed to switch the electric drive (34) into a generative brake operation in order to feed power generated by the drive at least partially back into the drive and thus to provide a braking force for braking a movement of the vehicle part. In this way, a drive device with a permanent magnet brake is provided which can be designed simply and in a space saving way to provide a reliable braking force.

Description

technical field [0001] The invention relates to a drive unit for adjusting vehicle components and a method for operating a drive unit according to the preamble of claim 1 . Background technique [0002] Such a drive device includes an electric drive for driving a vehicle component. The electric drive has an output shaft for transmitting the adjusting force to the vehicle component. A first braking device is connected to the output shaft, which has at least one permanent magnet element and is designed to provide a braking force for securing the vehicle component in the currently assumed position. [0003] In the drive device known from EP 1 940 012 A1, the braking device in the form of a so-called hysteresis brake has a plate-shaped carrier element connected to the driven shaft in a rotationally fixed manner, for example an annular ring made of soft magnetic material The hysteresis element is fixed on the carrier element. Two permanent magnets on the stator are opposite th...
