Abstract
Suspension strut which incorporates a jounce bumper of a suitable rubber or elastomer having an outwardly oriented knee which yields under low axial compression to provide a low initial spring rate as the suspension initially contacts the bumper. As the suspension travel increases, the knee in the bumper wall continues to yield so that the internal shape of the walls of the jounce bumper become active and progressively increases the effective contact area to provide a progressively increasing spring rate and improved jounce control.
