Abstract: A tire pressure control device of an off-road vehicle is configured for changing tire pressures of vehicle wheels of at least one vehicle axle. Each pneumatic tire has a pressure-controlled wheel valve which is pneumatically connected to a control pressure line and to a supply pressure line. The control pressure lines and the supply pressure lines are pneumatically connected to a compressed air supply device and controlled by an electronic control unit. The actuation of the wheel valves takes place axle by axle via control valves, and the compressed air supply of the vehicle wheels is carried out by side via supply valves.

Abstract: A suspension system includes spring bellows that are associated with pneumatic springs of vehicle axles, connectable by lines having level control valves to a main pressure line, and can be shut off with respect thereto. The main line is connectable by valves alternately to a compressed air source and a sink, and can be shut of with respect thereto. To set different air mass flow rates when air is supplied to/removed from the bellows, the bellows of the springs at least on a vehicle axle or side can be connected to the main line in parallel with the connecting lines, at least by further connecting lines having further level control valves, and can be shut off with respect thereto. The further valves have nozzle cross-sectional surfaces the same size as the other level control valves. Chokes are connected-downstream of the further valves in the ventilation direction, the cross-sectional surfaces thereof being smaller than the nozzle cross-sectional surfaces of the further valves.

Abstract: A valve arrangement (2a, 2b) of a hydraulically braked tractor vehicle for controlling the brake pressure of a pneumatically braked trailer includes an electronically controlled trailer control valve (6) with an inlet valve (14), an outlet valve (16), a pneumatical relay valve (18), a breakaway valve (20) and a brake control pressure sensor (24). The valve arrangement also has a hydraulically controlled backup valve (8) with a hydraulically activated relay valve (46), a redundancy valve (112, 112′) and a hydraulic control pressure sensor (50). Output-side brake control lines (40; 62) are connected via a shuttle valve (10) to a brake coupling head (82). The valves (14, 16, 18, 20) and the pressure sensors (24, 50) of the trailer control valve (6), the valves (46, 112, 112′) of the backup valve (8) and the shuttle valve (10) may be combined in one trailer control module (98) with a single housing (100).

The valve assembly includes an inlet valve arranged between the main brake line and one of the wheel brake lines, and an outlet valve arranged between the relevant wheel brake line and an unpressurized return line. The inlet valve and the outlet valve are pressure-controlled 2/2-way switching valves with correspondingly large switching cross sections, and the inlet valve and the outlet valve are each assigned at least one pilot valve designed as a solenoid switching valve.
