摘要： A vehicle-height control system including a tank, a compressor, an actuator, and a valve between the tank and the compressor. The valve is closed to a state of a pressure medium supplier to the compressor-pressure supply state when a tank pressure has reached a threshold in a tank-pressure supply state in which the tank pressure is supplied to the actuator. In the compressor-pressure supply state, the tank pressure is kept at the threshold, and a pressure in the actuator is greater than the tank pressure. The threshold makes it difficult for a pressure differential in the valve to become greater than a valve-opening pressure differential, making it difficult for the valve to be opened in the compressor-pressure supply state. This system enables good supply of a pressure medium from the compressor to the actuator, avoiding a longer time for vehicle height control and achieving a shorter compressor operation time.

A central air line is fluidly connected to the air spring and the compressor. At least one spring air line extends between the central air line and the air spring. At least one suspension valve is disposed along the spring air line. At least one auxiliary air line extends between the spring air line and the central air line. At least one high flow exhaust valve is disposed along the auxiliary air line. At least one isolation check valve is disposed in series with the high flow exhaust along the spring air line.

摘要： For adjusting the supporting load of a central axle trailer equipped with at least two axles having pneumatic suspensions and a pneumatic suspension system that includes separate pneumatic suspension circuits on the axles with pneumatic suspensions, a method and electronic control device are provided by which the respective quantities of air are separately adjustable. When the current supporting load exceeds a permitted supporting load range, the current supporting load is reduced by separate alteration of the quantity of air in at least one of the pneumatic suspension circuits; and, when the current supporting load is below the permitted supporting load range, the current supporting load is increased by separate alteration of the quantity of air in at least one of the pneumatic suspension circuits.

摘要： The object of the invention is to avoid pressure and volume compensation as much as possible during measurement of the pressures of the air spring units. According to the invention, the pressure in the air spring units (5, 6, 7, 8) is estimated prior to measurement of the pressures of the air spring units (5, 6, 7, 8) and is compared to the pressure in the air pressure accumulator (3). The higher of the two pressures determines the position of a 3/2 directional control valve (11) which separates the collector line (25) connecting all air spring units (5, 6, 7, 8) from the air pressure accumulator (3) or which connects it to as small a chamber volume of the supply system as possible.

摘要： A closed level control system includes an air dryer (10) which is mounted in a pressurized air line (4). The compressor output (16) can be connected to the pressurized air supply vessel (12) via the pressurized air line (4). Air from the atmosphere can be transferred via an intake valve (30) into the pressurized air supply vessel (12) via the compressor and the air dryer (10). Furthermore, pressurized air can be discharged into the atmosphere from the pressurized air supply vessel (12) via the air dryer (10) and the intake valve (30). There is a flow in the opposite direction through the air dryer than when filling the pressurized air supply vessel (12) from the atmosphere. In this way, an excellent regeneration of the air dryer (10) is ensured.

摘要： The invention relates to a closed level control system for a vehicle. The closed level control system includes a pump which transfers a pressurized medium between a pressurized medium supply vessel (4) and pressurized medium chambers (2a to 2d). The input (8) of the pump (6) is connected to the supply vessel (4) and the output (10) of the pump (6) is connected to the pressurized medium chambers (2a to 2d) when the pressurized medium is to be pumped from the supply vessel (4) into the pressurized medium chambers (2a to 2d). If, in contrast, pressurized air is to be pumped from a pressurized medium chamber (2a to 2d) into the supply vessel (4), then the input (8) of the pump (6) is connected to the pressurized medium chamber and the output (10) of the pump (6) is connected to the supply vessel (4). The above-mentioned connections preferably take place via controllable directional valves (14, 18). The level control system makes it possible that the pump (6) has to always run only in one direction.
