Abstract

A wheel suspension for land vehicles that is provided with a spring resting against at least one seat, with a dashpot, and with an attachment for a stabilizing rod, whereby one seat can be adjusted axially paralleling the spring. The object of the invention is to allow the stabilizing rod'"'"'s attachment to be situated in the vicinity of the seat. An attachment (10 or 20) for the stabilizing rod is accordingly directly mounted on or indirectly attached to the spring seat (8), or on or to the mechanism that adjusts it, at a variable distance from the seat.

Claims

1. Wheel suspension for land vehicles that is provided with a spring resting against at least one seat, with a dashpot, and with an attachment for a stabilizing rod, whereby one seat can be adjusted axially paralleling the spring, characterized in that an attachment (10 or 20) for the stabilizing rod is directly mounted on, or indirectly attached to, the spring seat (8) or on or to the mechanism that adjusts it at a variable distance from the seat.

2. Wheel suspension as in claim 1, characterized in that the spring seat (8) is attached to and can be adjusted in relation to the outer cylinder (2) of a dashpot or telescoping leg.

3. Wheel suspension as in claim 1 or 2, characterized in that the outer cylinder (2) of the dashpot or telescoping leg is provided with outside threading or annular grooves (7), whereby a fastening collar on the spring seat (8) and the contact surface of the attachment (10) for the stabilizing rod are both provided with matching inside threading or ridges, and are accordingly secured jointly or separately to the outer cylinder.

4. Wheel suspension as in one or more of claims 1 through 3, characterized in that the attachment (10 or 20) for the stabilizing rod is positioned on the outer cylinder (2) axially above or below the fastening collar on the spring seat (8).

5. Wheel suspension as in one or more of claims 1 through 3, characterized in that the attachment (10) for the stabilizing rod is positioned radially inside an unoccupied segment on the fastening collar of the spring seat (8).

6. Wheel suspension as in one or more of claims 1 through 5, characterized in that the fastening collar on the spring seat (8) and/or the contact surface of the attachment (10) for the stabilizing rod is or are surrounded or overlapped by a retaining ring (13) in the form of a tightening sleeve or tightening band.

7. Wheel suspension as in claim 1 or outer cylinder 2, characterized in that a fastening collar (14) on the spring seat (8) is provided with one or more longitudinal slits (15) that extend along axial flanges (16 &

17) penetrated by tensioning means, preferably threaded fasteners, that tighten the collar around the outer cylinder (2) and in that at least one of the tensioning means accommodates the attachment (20) for the stabilizing rod.
