TRAILING ARM SUSPENSION AND HEIGHT CONTROL SYSTEM WITH MOTORIZED VALVE THEREFOR

摘要

A trailing arm suspension for a vehicle. The trailing arm suspension has a height control system for maintaining the vehicle at a reference ride height. The suspension comprises a height sensor that senses the current vehicle ride height and generates an output signal representative of the current ride height. An inflatable bag is operably coupled between the axle and the vehicle whereby the introduction and exhaustion of air into and from the air bag increases and decreases the relative distance between the axle and the vehicle to adjust t he vehicle ride height. The ride height control system is characterized by a valve actuator, preferably comprised of a controller. The height sensor may be a transducer including an optical sensor arrangement.
