An air suspension system for a multi-axle vehicle has an air bag system including at least one air bag operatively associated with the vehicle wheels on selected wheel and axle sets to control relative movement between each of the selected wheels and a supporting frame structure of the vehicle. The system has an air-flow control arrangement to control the flow of air into each air bag to thereby control the relative movement of the wheels and vehicle frame structure. A pressurising arrangement is provided to maintain a selected, predetermined pressure in the air bag system when the vehicle is at rest to thereby maintain a desired vehicle height. The pressurising arrangement includes a valve to admit pressurised air to or exhaust air from the air bag system to maintain the predetermined vehicle height. The valve is actuated by a link associated with a rocker member connected to spaced axles of the vehicle.
An air suspension system for multiple axles of a multi-axle vehicle, comprising an air bag system including at least one air bag operatively associated with vehicle wheels on selected axle sets to control relative movement between each of the selected wheels and a supporting frame structure of the vehicle, an air-flow arrangement to control the flow of air at least into each air bag, a pressurising arrangement to maintain a selected, predetermined pressure in the air bag system when the vehicle is at rest, the pressurising arrangement including a valve to admit pressurised air to or exhaust air from the air bag system to maintain a predetermined vehicle height, wherein the valve is actuated by a link associated with a rocker member connected to spaced axles of the vehicle.
An air suspension system for a vehicle having a front differential and a rear differential or a rear axle, wherein a rocker member extends between the front differential and the rear differential or rear axle, and a link extends from a height control valve to a location approximately mid-point of the length of the rocker member.
