Abstract: A method is provided for receiving a vehicle cab in a reversible manner on an agricultural base vehicle. The method includes providing a supporting structure on the base vehicle and selectively receiving the vehicle cab in a receiving region of the supporting structure or removing the vehicle cab from the receiving region as a function of a predetermined operation of the base vehicle.

Abstract: A hydraulic arrangement (10) to increase a motor load is described. The hydraulic arrangement comprises a hydraulic consumer (28), a load pressure-controlled hydraulic pump (24), a hydraulic tank (26), and a hydraulic control circuit (30), connected with the hydraulic consumer (28), with which a volume flow conveyed by the hydraulic pump (24) can be changed, wherein the hydraulic control circuit (30) comprises an excess pressure valve (42) and an electronically controllable control valve (36). In order to ensure a prioritization of the hydraulic consumer with a simultaneous increase of the motor bad, a proposal is made that the hydraulic control circuit (30) comprise a load pressure-controlled pressure compensator (38) between the excess pressure valve (42) and the control valve (36).

Abstract: A suspension system is provided for a movable, supported vehicle axle. The suspension system includes a pair of hydraulic suspension cylinders, which are placed between the vehicle axle and a supporting vehicle structure. Each hydraulic suspension cylinder includes a first work chamber connected to a first pressure accumulator, and a second work chamber connected to a second pressure accumulator. A pressure-limiting valve is exposed to pressure in the first work chamber and has an outlet connected to the second pressure accumulator.

Abstract: A hydraulic system for a mobile working machine includes a hydraulic pump, a steering valve, a steering actuator controlled by the steering valve, a first hydraulic line which extends between the hydraulic pump and the steering valve, and a hydraulic storage unit which is connected with the first hydraulic line via a second hydraulic line). So as to optimize a pressure state for the hydraulic system, a throttle connected in parallel with a check valve is located in the second hydraulic line. The check valve permits one-way fluid flow in a direction away from the hydraulic storage unit.
