ELECTRONIC SUSPENSION AND LEVEL CONTROL SYSTEM FOR RECREATIONAL VEHICLES

摘要

The suspension and level control system for vehicles includes, so as to independently control inflation and deflation of left and right front and rear air-springs, corresponding left and right front and rear pneumatic circuits in fluid communication with a pressurized air source. Each air-spring may have at least one air ride cushion reservoir mounted in a parallel pneumatic circuit in parallel fluid communication with the air-spring. Each pneumatic circuit includes a selectively actuable valve for selectively passing pressurized air from the air source into the corresponding parallel pneumatic circuit to selectively inflate the corresponding air-spring thereby raising a corresponding corner of the vehicle; and for selectively venting pressurized air from the corresponding parallel pneumatic circuit to selectively deflate the corresponding air-spring, thereby lowering a corresponding corner of the vehicle. An anti-dive valve in each circuit having a cushion reservoir selectively isolates the corresponding reservoir upon a control signal from a processor triggered by input from accelerometers.
