Abstract

A torsion beam axle suspension is provided, in which a shock absorber is directly mounted on right and left trailing arms and is further mounted to the mount by a ball joint. Thus, it is possible to reduce the weight and production expenses, thus to enhance productivity. Further, it is possible to considerably decrease a friction caused by movement of the shock absorber even though the transverse force is applied, thus to enhance the riding comfort.

Claims

1. A torsion beam axle suspension comprising:

left and right trailing arms disposed in a longitudinal direction of a body; and

a torsion beam coupled to the left and right trailing arms,

wherein the left and right trailing arms are each provided with a mount for mounting a shock absorber.

2. The torsion beam axle suspension as claimed in claim 1, wherein the mount for the shock absorber comprises a ball joint.

3. The torsion beam axle suspension as claimed in claim 2, wherein the ball joint comprises:

a socket bored with at least one insert hole on both sides thereof, the insert hole receiving a fastener; and

a ball stud including a ball fitted pivotably in the socket and a stud that mounts to the shock absorber.
