ISOLATED LIFT ASSEMBLY FOR VEHICLE AUXILIARY SUSPENSION ARRANGEMENT

A vehicle suspension assembly includes a mounting bracket adapted to couple to a vehicle frame assembly, a trailing arm having a first end pivotably coupled to the first mounting bracket, and a second end, an axle member coupled to the second end of the trailing arm, the axle member configured to support a tire, an actuator operably coupled to the trailing arm and operable between a first state configured to lift the tire away from a ground surface and a second state configured for the tire to contact the ground surface, and an actuator arrangement configured to move from a first position where the actuator arrangement couples the actuator to the trailing arm when the actuator is in the first state, and a second position where the actuator arrangement uncouples the actuator from the trailing arm when the actuator is in the second state.
