Claims

[Scope of Claim for Utility Model Registration] ↓ A suspension unit provided for each M, which uses both an auxiliary air spring chamber and an auxiliary spring, and the left and right air spring chambers of the front and rear wheel sunpension units are connected. a pair of communication pipes, a single-use control valve installed in each of the pair of communication pipes, a reserve tank for storing compressed air, and an air spring chamber of the reserve tank and each suspension unit. Each suspension is connected to the piping that connects each suspension, an air supply control valve installed in each unit, and a compressed air flow path provided between the reserve tank and each air supply control valve divided into two large and small systems. an air supply flow path selection control valve that can be selected; an exhaust control valve that is installed in each suspension unit in the tR trachea that connects the air spring chamber of each suspension unit with the atmosphere; an exhaust flow path selection control valve provided between the exhaust control valve and the atmosphere and capable of selecting two types of compressed air flow paths, large and small; and an accelerator opening speed detection means for detecting an accelerator opening speed; When the accelerator opening speed detected by the accelerator opening speed detecting means exceeds a certain value, the front wheel side exhaust control valve and the rear wheel side air supply control valve are activated. After that, after a certain period of time has elapsed, press the accelerator.
Even if the opening speed becomes above a certain value again, the front wheel side exhaust control valve and the rear wheel side air supply control valve do not open. An electronic control system characterized by comprising a controller that controls the opening of the air supply control valve on the front wheel side and the exhaust control valve on the rear wheel side to control the vehicle body attitude when the speed becomes a negative value. Suspension device.
