    摘要: A vehicle suspension apparatus has air spring chamber provided at a suspension unit for supporting a rear wheel, air supply means for supplying air to the air spring chamber of the suspension unit for supporting the rear wheel through supply opening and closing valve, air exhaust means for exhausting air from the air spring means of the suspension unit for supporting the rear wheel, a parking brake sensor for detecting the operated state of a parking brake, and a shift position detecting sensor for detecting the shift position of an automatic transmission having a fluid drive unit for transmitting drive power to wheels. The parking brake sensor detects whether or not the parking brake is engaged. The shift position detecting sensor detects whether or not the shift position of the automatic transmission is operated from any of parking position (P) and neutral position (N) to running position (D, L, 2) to raise the vehicle height of the rear wheel side to supply air to the air spring chamber of the rear wheel side. The fact that the shifting position of the automatic transmission is operated from either the parking position (P) or the neutral position (N) to the running position (R) is detected to exhaust air from the air spring chamber of the rear wheel side to lower the vehicle height of the rear wheel.

    摘要: In a vehicle suspension apparatus having air spring chambers between the vehicle body and the respective wheels to perform height and position control modes by controlling supply control valve means for supplying air to the air spring chambers and exhaust control valve means for exhausting air from the air spring chambers, the vehicle suspension apparatus has a high-pressure reserve tank connected to the respective chambers through the supply control valves, a first compressor for supplying compressed air to the high-pressure reserve tank, a low-pressure reserve tank connected to the respective chambers through the corresponding exhaust control valves and the suction port of the first compressor, and a second compressor for supplying atmospheric air to the high-pressure reserve tank through a check valve and a drier arranged between the check valve and the second compressor. In the position control mode, the compressed air is exhausted from the chambers to the low-pressure reserve tank through the exhaust control valves. In the height control mode, the compressed air is slowly exhausted from the corresponding chambers through the exhaust control valve means via the drier, thereby regenerating the drier during height down control.

    摘要: In a vehicle suspension apparatus, front and rear wheel suspension units respectively have air spring chambers. Air is supplied to predetermined air spring chambers from an air source through a supply control valve, and at the same time air is exhausted from remaining air spring chambers through an exhaust control valve. Three-directional valves are inserted between the respective air spring chambers and the exhaust control valve. One end of a front wheel communication path is connected to the front left wheel three-directional valve and the other end of the path is connected to the front right wheel three-directional valve. Similarly, one end of a rear wheel communication path is connected to the rear left wheel three-directional valve and the other end of the path is connected to the rear right wheel three-directional valve. The air passing through the supply control valve is supplied to the front wheel air spring chambers through the front wheel communication path or to the rear wheel air spring chambers through the rear wheel communication path. Each of the three-directional valves can take the first position where the air spring chambers communicate with the supply control valve or the second position where the air spring chambers communicate with the exhaust control valve, thereby decreasing the numbers of valves and paths so as to perform position control.
