O Utility Model Registration Claims A lateral acceleration detection means for detecting lateral acceleration acting on the vehicle body, a suspension unit provided for each wheel and each having its own air spring chamber, and air on the left and right sides of the front and rear suspension units. A pair of connecting pipes connecting the honeycomb chambers, a communication control valve interposed between the air spring chambers of each suspension unit of the connecting pipe, a reserve tank for storing compressed air, and the reserve tank. An air supply control valve provided for each suspension unit is installed in an air supply pipe that connects the air spring chamber of the suspension unit, and an exhaust gas that connects the air spring chamber of each suspension unit with the exhaust pipe. an exhaust control valve provided for each suspension unit installed in the service piping, and a communication control valve when the lateral acceleration detected by the lateral acceleration detection means is determined to be equal to or higher than a predetermined value;
An electronically controlled suspension device comprising: a controller that controls the opening and closing of an air supply control valve and an exhaust control valve to control posture.

Claims (1)

[Scope of utility model registration request] A suspension unit provided for each wheel that uses a combination of a lateral acceleration detection means that detects lateral acceleration, main and auxiliary air spring chambers, and auxiliary springs, and a connection between the left and right main air spring chambers of the front and rear wheel suspension units. a pair of connecting pipes, a communication control valve interposed between the main air spring chambers of each suspension unit of the connecting pipe, a reserve tank for storing compressed air, and a communication control valve between the reserve tank and the suspension unit. An air supply control valve provided for each suspension unit installed in an air supply pipe connecting the main air spring chamber, and an exhaust pipe connecting the main air spring chamber of each suspension unit and the exhaust pipe. an exhaust control valve provided for each suspension unit installed in the suspension unit, and the communication control valve when the lateral acceleration detected by the lateral acceleration detection means is determined to be equal to or greater than a predetermined value; An electronically controlled suspension device comprising a controller that controls the opening and closing of an air supply control valve and an exhaust control valve to control posture.
