## Abstract

In a mounting arrangement for a torsion bar of a torsion bar vehicle wheel suspension wherein the torsion bar is mounted at its one end to a cross link of a vehicle wheel suspension the other end of the torsion bar is connected to a mounting shoe which is engaged with the vehicle chassis only by the torque forces transmitted through the torsion bar.

## Claims

### Claim 1

A mounting arrangement for an end remote from a wheel of a torsion bar of a torsion bar suspension for a vehicle wheel which is supported on a vehicle chassis by cross-links, said mounting arrangement comprising: a mounting shoe arranged at the end of said torsion bar remote from said wheel and firmly fastened to said torsion bar so as to be non-rotatable relative to said torsion bar at least counter to a torque applied to the torsion bar by the associated wheel, said mounting shoe being engaged with said chassis only by the torque force effective on said mounting shoe.

### Claim 2 (depends on 1)

A torsion bar mounting arrangement according to claim 1, wherein said chassis includes a crossmember joined to a longitudinal frame member, said cross member having an opening at its bottom in the region adjacent said longitudinal frame member and said mounting shoe has a first flange surface engaging the underside of said longitudinal frame member and at its opposite end a second flange engaging said crossmember.

### Claim 3 (depends on 1)

A torsion bar mounting arrangement according to claim 1, wherein, within said mounting shoe, a control lever is mounted on the end of said torsion bar remote from said wheel and is adjustably supported within said mounting shoe.

### Claim 4 (depends on 3)

A torsion bar mounting arrangement according to claim 3, wherein said mounting shoe comprises a base plate with upwardly projecting reinforcement walls and said control lever rests on a bearing part disposed on said base plate, said control lever having a free end connected to a region of said base plate remote from said bearing part by means of an adjusting bolt which retains said control lever and the end of said torsion bar in an adjustable position.

### Claim 5 (depends on 1)

A torsion bar mounting arrangement according to claim 1, wherein said mounting shoe is supported on said chassis with a tolerance range permitting adjustment movement in axial direction of said torsion bar.
