Abstract

A maneuvering drive (24, 30) for a trailer (10) has a central unit (30) and at least two drive units (24) associated with wheels (16) of the trailer (10), each drive unit (24) including an electric drive motor (26) having a mechanical brake (40) associated therewith, an additional brake module (50) being provided which allows an additional braking effect of the drive units (24) to be generated in addition to the mechanical brake (40).

Claims

1. A maneuvering drive for a trailer, comprising a central unit and at least two drive units associated with wheels of the trailer, each drive unit including an electric drive motor having a mechanical brake associated therewith, an additional brake module being provided which allows an additional braking effect of the drive units to be generated in addition to the mechanical brake.

2. The maneuvering drive according to claim 1, characterized in that the additional brake module seeks to actively control the speed of the drive motor to 0 rpm.

3. The maneuvering drive according to claim 1, characterized in that the central unit or the corresponding drive unit includes a wake-up module which is adapted to activate the central unit or the drive unit when it is supplied with electrical energy.

4. The maneuvering drive according to claim 3, characterized in that the electrical energy generated in generator mode of the drive motors is made use of for supplying the central unit or the drive unit, for the latter to control the drive motors to a speed of 0 rpm.

5. The maneuvering drive according to claim 1, characterized in that a short-circuit switch is provided by which the drive windings of the drive motors can be short-circuited.

6. The maneuvering drive according to claim 5, characterized in that the short-circuit switch short-circuits the drive windings of the drive motor with the central unit switched off or with the drive unit switched off.

7. The maneuvering drive according to claim 5, characterized in that the short-circuit switch is arranged in the drive unit.

8. The maneuvering drive according to claim 1, characterized in that the additional brake module is arranged in the drive unit.

9. The maneuvering drive according to claim 6, characterized in that the short-circuit switch is arranged in the drive unit.
