Lift axle suspension with axle reservoir |
摘要 |
A trailing arm suspension, alone or in combination with a vehicle having a vehicle frame supported by an axle with ground engaging wheels. The trailing arm suspension comprises a pair of spaced trailing arm assemblies, each of which includes a trailing arm pivotally mounted to a the vehicle frame and a spring operably coupling the trailing arm to the frame to resist the pivotal movement of the trailing arm. A pneumatic lift mechanism is provided to selectively raise the trailing arm relative to the frame. The axle has at least a portion of which that is hollow and defines a pressurized air reservoir, which is coupled to the spring and/or the pneumatic lift mechanism to provided pressurized air for altering the resistance of the spring and/or actuating the pneumatic lift mechanism to selective lift the trailing arm.
