Abstract

A suspension mechanism is provided for a motor vehicle including an axle, a spring seat, an isolator, and a coil spring. The spring seat is coupled to the axle and includes an aperture formed at a pre-selected location therein. An isolator is disposed on the spring seat and includes a locating member in the form of a projection extending therefrom. The projection engages the aperture in the spring seat so that the isolator assumes a preselected orientation relative to the spring seat when positioned thereon. A coil spring is secured to the isolator by a retention member in the form of an annular groove having a plurality of discrete protrusions overlapping the lowest coil of the coil spring. An orientation member in the form of a second projection is provided at a preselected location on the isolator. The second projection engages an end of the coil spring to that the coil spring assumes a preselected orientation relative to the isolator. The isolator also includes a plurality of notches formed about a perimeter thereof for interrupting a path for vibrations through the isolator.
