ABSTRACT:
An air spring assembly is mounted to a shock absorber to form a strut assembly. The shock absorber includes an outer cylinder with a shock piston and piston rod mounted within the outer cylinder. The outer cylinder includes a shock mount that is attached to a vehicle wheel. The air spring assembly includes an upper mount, which is attached to a vehicle body member, and a lower mount that is attached to the outer cylinder. An air spring piston is mounted to the upper mount via a bearing assembly to permit relative rotation between the air spring piston and the vehicle body member. A flexible member extends from the lower mount to a lower end of the air spring piston. The piston rod is mounted at one end to the shock piston and at an opposite end to the air spring piston. An isolator is mounted between the piston rod and the air spring piston to minimize shock loads.
