A four point link suspension for a vehicle, wherein the suspension comprises: a first side suspension spring, configured to absorb a vertical load; a second side suspension spring, configured to absorb the vertical load, wherein the springs are configured to be connected to a vehicle frame via a respective joint; a stabilization frame, comprising a first side link arm having a first ending and a second ending connected to the first side suspension spring via a second joint; a second side link arm and a second ending connected to the second side suspension spring via a second joint; and a torsion bar, connecting the side link arms, which side link arms are tapered towards the respective first ending.

Disclosed herein is an axle cartridge member for receiving a pair of torsion stub axles. The axle cartridge member includes a pair of laterally opposed bases, with each base defining a cavity therein for receiving an elongated stub housing of the torsion stub axles. The axle cartridge member also includes a pair of axle mounts that each includes a lateral opening extending into the cavity defined in the respective base, and an arch including a crossbar extending at a height above the bases wherein the arch further includes a portion that extends upward from each of the bases at an angle and meets the crossbar that extends generally horizontally between the portions of the arch.

A spring arrangement for suspending a wheel suspension element relative to a vehicle body includes a spring element extending along a torsion axis and having a multiplicity of torsion portions arranged one around another in radial succession. Adjacent torsion portions are predominantly separate from one another in each case, but connected in a rotationally fixed manner in certain regions by a connecting portion. An innermost torsion portion and an outermost torsion portion each have an attachment region and one attachment region is connected to the vehicle body and the other attachment region is connected to the wheel suspension element. A controllable actuator may act on different torsion portions of the spring element relative to the vehicle body and to set the characteristics of the spring arrangement.
