MacPherson strut assembly

A MacPherson strut assembly (10) is provided that has a hydraulic cylinder (12) with a fluid chamber. A piston (14) is arranged in the chamber, and a rod (16) extends from the piston. A lower spring seat (20) is supported on the hydraulic cylinder, and an upper spring seat (18) is supported on the rod. A coil spring (26) is arranged between the spring seats to produce a desired spring loading. In one embodiment, a compliant isolator (24) having a sloped profile (32) is arranged on the lower spring seat to produce an uneven spring loading. In another embodiment, a spring seat isolator (39) may include materials of a different stiffness to produce uneven spring loading. An isolator (56, 58) may also be used between coils of the spring so that the compression on one side of the spring is limited more that the opposite side to produce uneven loading.
