A tire pressure regulating system is disclosed for adjusting tire pressures of pneumatic tires of vehicle wheels of a plurality of vehicle axles of a motor vehicle while driving. The tire pressure regulating system comprises: at least one switchover valve, an axle valve, a wheel valve and a valve. A motor vehicle comprising the tire pressure regulating system is also disclosed.

Tire pressure control system

A strain relief arrangement () for a connecting cable () has a threaded pin (), clamping tongues (), a union nut (), an enlarged diameter () on the threaded pin (), an extension (), and a passage bore () for the connecting cable (). By screwing of the union nut () onto the threaded pin (), the clamping tongues () move inward and press against the connecting cable () for strain relief. The extension () is non-round, and an opening () of a carrier element () is complementary () to the extension (). An enlarged region () of the extension () has a circumferential groove () adjacent to the enlarged diameter (). The extension () can be introduced into the opening () of the carrier element () and can be fastened by rotation in the opening ().

Plug coupling with strain relief for a connecting cable

A tire pressure regulating device for adjusting, while driving, the tire pressures of vehicle wheels of a plurality of vehicle axles of a motor vehicle with pneumatic tires includes at least one switchover valve arranged on the vehicle chassis that can be controlled in an electromagnetic/pneumatic manner, a plurality of axle valves, each axle valve being arranged on the vehicle chassis for each vehicle axle and being controllable in an electromagnetic/pneumatic manner, a plurality of pressure-controlled wheel valves, each pressure-controlled wheel valve being arranged at a respective vehicle wheel, a pilot control valve arranged on the vehicle chassis and being controllable in a purely electromagnetic manner or in an electromagnetic/pneumatic manner, and a plurality of two-channel rotary couplings arranged between the vehicle axles and associated vehicle wheels and provided with switchable seals.

Tyre pressure regulating device

A suspension system includes spring bellows that are associated with pneumatic springs of vehicle axles, are 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 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.

Pneumatic suspension system of a motor vehicle and method

An electropneumatic control arrangement for an automatic vehicle level control system, particularly of a commercial vehicle, includes at least; a solenoid valve unit having at least two electropneumatic solenoid valves, a compressed air inlet for infeeding compressed air, at least one compressed air connection for at least one air bellows and electrical control inputs, and an electronic control unit for actuating the solenoid valve unit. The electronic control unit comprises control outputs for electrically connecting to the control inputs of the solenoid valve unit. A plug connector is configured on the housing of the solenoid valve unit, in which the electrical control inputs are disposed, and a plug connector is provided on the housing of the electronic control unit, in which the control outputs are disposed. The plug connectors are mechanically plugged into each other.
