Abstract
A spring and strut mount assembly for an automotive vehicle including a strut in the form of a shock absorber having a piston reciprocable within a cylinder, and a piston rod extending axially outwardly from the piston through a cap on an end of the cylinder. The assembly also includes a strut mount adapted to be secured to rigid frame structure of the vehicle. The piston rod is secured to the strut mount. A spring unit resists retraction of the piston rod into the cylinder. A jounce bumper of flexible compressible material is sleeved on the rod between the strut mount and the end of the cylinder. The jounce bumper is compressed axially by contact with the end of the cylinder when the piston rod strokes. A cup is provided to limit radially outward expansion of the jounce bumper when it is compressed by the end of the cylinder. The cup includes a side wall of plastic material surrounding the jounce bumper. The base of the cup is a metal washer.
