An insulator for a vehicle includes a first portion extending along an axis, an intermediate portion extending from the first portion along the axis, and a second portion extending from the intermediate portion along the axis. The first portion defines a first density and the second portion defines a second density different from the first density. Preferably, the first density is greater than the second density such that the second portion is more compressible than the first portion. The first portion, the intermediate portion, and the second portion are integrally formed of a common homogeneous microcellular polyurethane material for defining a one-piece insulator having different densities. In exemplary embodiments, the insulator is further defined as a jounce bumper or a coil spring isolator for disposition in a wheel suspension system, and a body insulator for disposition in a mount assembly of a vehicle.

Front strut air spring suspension system
A steerable front suspension system provides a strut isolator assembly that is supported upon a bearing assembly mounted to a frame bracket. The forces upon a piston rod are transferred to the frame bracket through the strut isolator assembly that is rotationally supported upon the bearing assembly. The forces upon a spring assembly pass through an upper spring mount, a flange portion of the strut isolator assembly, the bearing assembly and into the frame bracket. An air bag is mounted to a jounce bumper bracket. An annular piston rod seal such as an O-ring seal is mounted about a reduced diameter piston rod segment adjacent a step upon which the jounce bumper bracket is located. The air chamber formed by the air bag is thusly sealed to the piston rod by the annular retainer and the annular piston rod seal.
