| Abstract |
A system for controlling the distance between a vehicle axle and a vehicle comprises: a sensor (144) that senses a distance between the vehicle axle and the vehicle frame (144) and generates a signal indicative thereof: a housing (202,204) having a wall (262) that at least partially defines a chamber (260), having an inlet port (216), an operation port (218), and an exhaust port (220) extending therethrough; a movable plate (273) with aside sealable against the wall (262) by pressurized air supplied to the chamber (260) a motor (224) for moving the plate, according to the signal the wall (262) by pressurized air supplied to the chamber (260); a motor (224) for moving the plate, according to the signal, between a fill position in which the operating port is connected to the inlet port, and an exhaust position in which the operating port is connected to the exhaust port to selectively control the distance between the vehicle axle and the vehivleame |
