Abstract

Wheel suspension has a steering knuckle support with two hole openings opposed to one another in an axial direction and form openings of a mounting hole, two axle pins spaced apart axially, extend in axial direction and engage in the mounting hole through the hole openings, and a chassis component supported at axial end portions of the axle pins to be swivelable relative to the steering knuckle. A first contact area at the hole openings has a conical inner circumferential surface. The conical inner circumferential surfaces of the first contact areas narrow in diameter toward one another in axial direction. The axle pins have a second contact area with a conical outer circumferential surface that narrow in diameter toward one another in axial direction and contact the conical inner circumferential surfaces of the first contact areas.

First claim

The invention claimed is:

1. A wheel suspension for a vehicle, comprising:
a steering knuckle support provided two hole openings that are opposed to one another in an axial direction and form openings of at least one mounting hole which is provided in the steering knuckle support and which extends in axial direction;
two axle pins that are axially spaced apart extend in the axial direction and engage in the at least one mounting hole through the hole openings;
a chassis component supported at axial end portions of the two axle pins to be swivelable relative to the steering knuckle support around a swiveling axis extending in the axial direction;
respective conical washers configured to form a respective first contact area at each hole opening and each having a conical inner circumferential surface, wherein the conical inner circumferential surfaces of each respective first contact areas narrow in diameter toward one another in axial direction
wherein the conical washers each have a cylindrical tube portion at their respective axial ends which face one another, which cylindrical tube portion, inside the at least one mounting hole, contacts the steering knuckle support by its outer circumferential surface and contacts the respective axle pin by its inner circumferential surface; and
a respective second contact area with a conical outer circumferential surface of each of the two axle pins have a conical outer circumferential surface, wherein the conical outer circumferential surfaces of each respective second contact areas narrow in diameter toward one another in axial direction and contact the conical inner circumferential surfaces of the first contact areas.

2. The wheel suspension according to claim 1 , wherein the first contact areas are formed by the conical washers inserted into the hole openings and at which the conical inner circumferential surfaces are provided.

3. The wheel suspension according to claim 2 , wherein each of the conical washers is connected to the steering knuckle support so as to be rigid against rotation with respect to the swiveling axis.

4. The wheel suspension according to claim 2 , wherein the conical washers each have a cylindrical tube portion at their respective axial ends which face one another, which cylindrical tube portion, inside the at least one mounting hole, contacts the steering knuckle support by its outer circumferential surface and contacts the respective axle pin by its inner circumferential surface.

5. The wheel suspension according to claim 1 , wherein the two axle pins have threads on their radially outer surface by which they are screwed into the at least one mounting hole.

6. The wheel suspension according to claim 1 , wherein the at least one mounting hole is a through-hole, the two axle pins each have an axially through-going cavity, and an inner part is provided that extends in axial direction through the axially through-going cavities.

7. The wheel suspension according to claim 6 , wherein two axial securing elements are provided at the inner part, the two axle pins being arranged therebetween and secured to the inner part in axial direction by positive engagement.

8. The wheel suspension according to claim 6 , wherein the inner part is connected to one of the two axle pins to be rigid against rotation.

9. The wheel suspension according to claim 6 , wherein a recess with an inner circumferential surface, which is nonround in cross section, is provided in each instance in front sides of the end portions of the two axle pins, this inner circumferential surface being engaged by a correspondingly shaped outer circumferential surface of an insert that is inserted into the recess, surrounds the inner part and is connected to the inner part to be rigid against rotation.

10. The wheel suspension according to claim 9 , wherein a respective joint is arranged on the end portions of each of the two axle pins, wherein the chassis component is mounted at the end portions of the two axle pins by the respective joints to be swivelable around the swiveling axis relative to the steering knuckle support.

11. The wheel suspension according to claim 1 , wherein the chassis component is a steering knuckle.

12. The wheel suspension according to claim 11 , wherein a vehicle wheel is mounted on the steering knuckle to be rotatable around a wheel rotation axis.

13. The wheel suspension according to claim 1 , wherein a plurality of chassis links connect the steering knuckle support to a chassis frame.
