A suspension system for a vehicle axle including at least one hydraulic suspension cylinder, which has at least one chamber, with the chamber being connected to a hydraulic accumulator and allowing a connection via switching arrangement as well as to a pressure source and a pressure release. A shut-off valve is arranged between the chamber and the accumulator, by which the suspension can be blocked. In order to avoid during the unblocking process that any sudden compensating motion of the axle suspension develops, here the suspension system includes at least one detection device connected to the chamber of the suspension cylinder and the accumulator, which is embodied to detect the pressure difference between the chamber and the accumulator. This way a pressure difference can be reliably detected at both sides of the shut-off valve, thus between the chamber of the suspension cylinder and the accumulator, and can be compensated in a targeted fashion during or before the opening of the shut-off valve for unblocking the suspension.

Suspension system for a vehicle axle

A vehicle includes a support structure and a suspension for an oscillatingly supported, rigid axle body. The suspension has a suspension device which is located between the axle body and the support structure and acts in a height direction of the vehicle. The vehicle further includes a plurality of coupling sites and a transverse link extending in a transverse direction of the vehicle. The transverse link is coupled to the support structure via a first link area and via a second link area and a pendulum support to the axle body. The transverse link includes a third link area which, with reference to the pendulum support in the transverse direction of the vehicle, is located opposite the first link area and is flexibly connected with a coupling site of the suspension device.

Vehicle with axle suspension

A control device of a vehicle suspension has a suspension device mounted between a supporting vehicle structure and a vehicle part that is movably mounted. The control device includes a blocking device for blocking a compression or rebound motion occurring at the suspension device in correspondence with a blocking command transmitted to a control unit. The control unit determines a characteristic weight value for a current loading of the suspension device when the blocking command is set and stores it as a pertinent value in a memory unit. The control unit determines a value for the weight when the blocking command is reset in order to cancel a blocking of the suspension device according to the result of a comparison with the value stored in the memory unit.
