ABSTRACT:
A lift axle suspension system for use on a vehicle having a chassis. The lift axle suspension system includes an axle assembly that is operably coupled to the vehicle chassis with a support arm assembly. A support biasing member is located between the axle assembly and the vehicle chassis for transferring loads between the axle assembly and the vehicle chassis. A lift spring member is also provided. The lift spring member is an air spring member and has one end that is pivotally mounted. Extension of the lift spring member lifts the axle assembly from a use position where the wheels attached to the axle assembly are engageable with a road surface to a storage position where the wheels attached to the axle assembly are not engaged with the road surface.
