Abstract

A stabilizer assembly unit having a first stabilizer and a sun gearwheel connected non-rotatably to one end of the stabilizer includes at least one rotary drive acting on a planetary gearwheel which meshes with the sun gearwheel. For a vehicle axle having at least two wheels, a separate stabilizer assembly unit according to any of the preceding claims may be provided for each of the wheels. In a chassis assembly unit for a vehicle having a body and a stabilizer assembly unit, the internally geared wheel is connected non-rotatably to the vehicle body.

Claims

1. A stabilizer assembly unit comprising a first stabilizer, a sun gearwheel connected non-rotatably to one end of the stabilizer, and at least one rotary drive acting on a planetary gearwheel which meshes with the sun gearwheel.

2. The stabilizer assembly unit according to claim 1, wherein several rotary drives are provided, each acting on a planetary gearwheel, the planetary gearwheels being arranged symmetrically relative to the axis of the sun gearwheel.

3. The stabilizer assembly unit according to claim 1, wherein the rotary drives comprise electric motors.

4. The stabilizer assembly unit according to claim 1, wherein the rotary drives are connected non-rotatably to a second stabilizer.

5. The stabilizer assembly unit according to claim 1 wherein an internally geared wheel is provided, which meshes via at least one auxiliary gearwheel with the planetary gearwheels.

6. A vehicle axle comprising at least two wheels, characterized in that for each of the wheels a separate stabilizer assembly unit according to claim 1 is provided.

7. A chassis assembly unit for a vehicle comprising a body and a stabilizer assembly unit according to claim 5, wherein the internally geared wheel is connected non-rotatably to the vehicle body.

8. A vehicle axle comprising:

at least one wheel at each end of the axle; and

a respective stabilizer assembly unit associated with the at least one wheel of each end of the axle, the stabilizer assembly units each including

a stabilizer;

a sun gearwheel connected non-rotatably to one end of the stabilizer;

a planetary gearwheel which meshes with the sun gearwheel; and

at least one rotary drive acting on the planetary gearwheel.
