Abstract

An axle device for the connection of a wheel to the body of a vehicle, having a wheel carrier for the fastening of the wheel, a first link and a second link for force-transmitting connection to the body, which links are both connected to the wheel carrier, furthermore having a supporting link with a carrier portion, which is connected to the wheel carrier, and with a body portion for force-transmitting connection to the body. The supporting link has a spring portion or supporting a spring unit and a damper portion for supporting a damper unit, which spring portion and damper portion are spaced apart from each other in the direction of travel of the body. The body portion has a torsion support portion with fastening freedom in the direction of travel and in the transverse direction of the body and with fastening stiffness in the vertical direction of the body.

First claim

What is claimed is:

1. An axle device for connecting a wheel to a body of a vehicle, the axle device comprising:
a wheel carrier configured to be fastened to the wheel,
a first link and a second link for force-transmitting connection to the body, which links are each connected to the wheel carrier,
a supporting link with a carrier portion, which is connected to the wheel carrier, and with a body portion for force-transmitting connection to the body, wherein the supporting link has a spring portion for supporting a spring unit and a damper portion for supporting a damper unit, which spring portion and damper portion are spaced apart from each other in a direction of travel of the body,
wherein the body portion of the supporting link has a torsion support portion with fastening freedom in the direction of travel of the body and in a transverse direction of the body and with fastening stiffness in a vertical direction of the body.

2. The axle device as claimed in claim 1 , wherein the torsion support portion is configured as a coupling portion.

3. The axle device as claimed in claim 2 , wherein the torsion support portion in the form of the coupling portion has a movement clearance in the transverse direction and in the direction of travel of the body.

4. The axle device as claimed in claim 1 , wherein the torsion support portion has a bearing portion with bearing degrees of freedom in the direction of travel of the body and in the transverse direction of the body.

5. The axle device as claimed in claim 4 , wherein the torsion support portion in the form of the bearing portion for forming the bearing degrees of freedom has elasticity in the direction of travel or in the transverse direction of the body.

6. The axle device as claimed in claim 1 , wherein the supporting link has a line of dynamic effect along which the force is transmitted between the wheel carrier and the body, wherein the spring portion and the damper portion are arranged on different sides of the line of dynamic effect.

7. The axle device as claimed in claim 6 , wherein a distance between the spring portion and the line of dynamic effect corresponds or substantially corresponds to a distance between the damper portion and the line of dynamic effect.

8. The axle device as claimed in claim 1 , wherein the torsion support portion has a connection arm for the connection to the body.

9. The axle device as claimed in claim 1 , wherein the body portion of the supporting link also has, in addition to the torsion support portion, at least one fastening portion for fastening to the body.

10. A vehicle with the body and at least two axles, wherein at least one axle has one of said axle devices according to claim 1 on each side of the body.
