Abstract:
A vehicle having an air suspension system is provided to use a spare tire as an air storage tank, thereby reducing a system installation space. A vehicle having an air suspension system comprises: a spare tire(110); a control unit(120) to adjust the height of a vehicle; and a system line(130) to connect the spare tire and the control unit in order to flow the air. The spare tire includes an air inlet. An opening connector is located in the end of the system line so as to open the air inlet. The control unit consists of: a manifold whose one end is connected to the system line; an air spring connected to the other end of the manifold and adjusted by pneumatic pressure; and an on/off valve to control the incoming and outgoing of the air.
Abstract:
A vehicle air suspension apparatus and a control method thereof are provided to protect the compressor with a comp-solenoid valve when charging the tank, and to prevent over-charge of the air tank by discharging the air through bypass valve when operating the compressor to charge the vacuum tank only. A vehicle air suspension apparatus comprises an air suspension(10), an air tank(20) for compression and a vacuum tank(30) for pressure reduction which are connected to the air suspension, an ECU(Electric Control Unit,40) in which pressure signal of the vacuum tank and the air tank is inputted, a compressor(50) which is connected to the air tank and the vacuum tank and operated by the ECU, a comp-solenoid valve(60) which is installed between the compressor and the vacuum tank and protects the compressor, and a bypass valve(70) which is installed between the compressor and the air tank and controlled by the ECU.

Abstract:
PURPOSE: A pipe assembly of a solenoid valve for an electronically controlled suspension is provided to secure air-tightness by adding an O-ring to a core inserted into the bottom of a pipe. CONSTITUTION: A pipe assembly of a solenoid valve for an electronically controlled suspension comprises a pipe(10), a valve(20), and a core(30). The pipe has a fastening unit(11), a guide unit(12), and an insertion unit(13). The top of the fastening unit is opened. The guide unit is vertically extended from the bottom of the fastening unit. The valve is adhered to the inner surface of the guide unit and the fastening unit. The core is inserted into the inner side of the insertion unit. The core is formed by installing an O-ring(32) in an O-ring groove(31).
Abstract:
An air suspension system is provided to prevent failure or damage to the system due to overheat when switching valves are kept on for a long time by operating on/off of the switching valves alternately and discharging compression air to two paths alternately. An air suspension system comprises air springs(120), spring opening and closing valves(125), an air tank(140), a compressor(160), first, second, and third switching valves(162,164,166), and vent valves(130). Compression air is stored up in the air tank. The compressor is placed between the air spring and the air tank. The first switching valve communicates with the air springs and with an input end(160a) and an output end(160b) selectively. The second switching valve opens and closes a path between the input end of the compressor and the air tank. The third switching valve opens and closes a path between the output of the compressor and the air tank. The vent valves are connected with the first switching valve and the air spring to control the discharge of the air. The compression air stored in the air tank passes through a path connected with the second and first switching valves and passes through a path connected with the third and first switching valves.
