Abstract:
A lift axle suspension system is provided with a frame bracket member connectable to a vehicle frame, an upper control arm, and a lower control arm. Each control arm has a first end and a second end, with the first end of each control arm being pivotally connected to the frame bracket member. The suspension system also includes an axle connecting member connectable to an axle, with the second end of each control arm being pivotally connected to the axle connecting member. A compression coil spring having a first end connected to the lower control arm and a second end connected to the upper control arm serves as a lift mechanism for lifting and lowering the axle connected to the axle connecting member. The compression coil spring may encircle at least a portion of and be substantially coaxial with the lower control arm.
