    • 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.

    • 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.
    • 在车辆悬架装置中,前轮和后轮悬挂单元分别具有空气弹簧室。 空气通过供给控制阀从空气源供给到规定的空气弹簧室,同时空气从剩余的空气弹簧室排出通过排气控制阀。 三相阀插入相应的空气弹簧室和排气控制阀之间。 前轮连通路的一端与左前轮三通阀连接,另一端与右前轮三通阀连接。 类似地,后轮连通路的一端连接到左后轮三通阀,另一端连接到右后轮三通阀。 通过供给控制阀的空气通过前轮连通路径或后轮空气弹簧室经由后轮连通路径被供给到前轮空气弹簧室。 每个三向阀都可以进入空气弹簧室与供应控制阀连通的第一位置或空气弹簧室与排气控制阀连通的第二位置,从而减少阀和通道的数量,从而 执行位置控制。
