Patent attributes
A driving device for moving a tailgate of a vehicle, comprising a permanent magnet brake, which comprises a stationary portion, a first braking element, which is rotatable relative to the stationary portion about a rotational axis, and a second braking element, which is arranged in a rotationally fixed manner on the stationary portion, is axially offset from the first braking element along the rotational axis and cooperates with the first braking element in order to generate a braking force. The first braking element and/or the second braking element have a permanent magnet or are formed by a permanent magnet, a magnetic attraction force acts between the first braking element and the second braking element axially along the rotational axis. Axially between the first braking element and the second braking element is arranged a friction element, which is in frictional contact with the first braking element and the second braking element.
