A suspended axle for a tractor, the axle having a lower link mechanism selectively operable between a first configuration in which the lower links are in fixed relation to the suspended axle and a second configuration in which the lower links are isolated from the suspended axle.

The invention relates to a link unit, in particular for use in utility vehicles, comprising an arm element and a load-bearing element, wherein the arm element has a holding section and the load-bearing element has an engagement section, wherein the holding section and the engagement section can be placed in positively locking engagement such that the load-bearing element is secured against displacement relative to the arm element in at least three holding directions which lie in a holding plane. The invention also relates to a method for producing a link unit.

A fluid-based suspension system of a vehicle including a first suspension device comprising a movable first piston dividing a first cylinder into a first piston rod side chamber and a first piston side chamber. The fluid-based suspension system further including a second suspension device, comprising a movable second piston dividing a second cylinder into a second piston rod side chamber and a second piston side chamber, and a fluid connection system configured to set the fluid-based suspension system to one of a first and a second operating mode.

A work vehicle comprising a vehicle support structure, a vehicle axle, a longitudinal rocking arm attached to the vehicle axle and comprising a first connection locus connected to the vehicle support structure, a sensor configured for detecting movement of the vehicle axle and a vehicle suspension system comprising a vehicle suspension link device comprising a link element comprising a second connection locus connected to the vehicle axle and a third connection locus connected to the vehicle support structure. The work vehicle comprises a sensor link comprising a first attachment point connected to the vehicle axle and a second attachment point connected to the sensor, the first attachment point being located on a virtual straight axis connecting the first connection locus of the longitudinal rocking arm and the second connection locus of the link element.
