Abstract
A jounce bumper of an automotive vehicle suspension system contains a longitudinal axis. The jounce bumper is configured to resiliently deform between an uncompressed state and a compressed state, where in the compressed state the jounce bumper has a smaller length in the direction of the longitudinal axis than in the uncompressed state. The jounce bumper also contains a base body that acts as a primary spring element, where the base body is partially or completely made of a volume-compressible first material. In particular, the base body further contains at least one secondary spring element integrated within the base body. The secondary spring element is resiliently deformable between a first length in the uncompressed state and a second length in the compressed state, where the second length is smaller than the first length. The secondary spring element is partially or completely made of a compact second material.
