  • Patent number: 11959526
    Abstract: A spring element, in particular a jounce bumper, for a jounce bumper assembly, contains a longitudinal axis, a base body extending along the longitudinal axis, and an end portion configured for being brought into contact with a vehicle part moving relatively to the spring element. The base body is elastically deformable between an uncompressed basic state and a compressed state in which the base body is at least partially compressed in the direction of the longitudinal axis. The end portion contains a circumferential outer surface, and at least one recess in the circumferential outer surface. The recess extends inwards and defines a hollow space in the base body.
    Type: Grant

  • Patent number: 11667169
    Abstract: A spring element, in particular a jounce bumper, for a vehicle suspension contains a longitudinal axis, a base body extending along the longitudinal axis, and an end portion positioned on a base end of the base body. The base body is elastically deformable between an uncompressed basic state and a compressed state in which the base body is at least partially compressed in the direction of the longitudinal axis. The end portion is configured for mounting the base body in a mounting cap. It is suggested that the end portion contains a plurality of at least two radially extending retention elements that are spaced apart from one another in the direction of the longitudinal axis, and each of the retention elements are configured to engage a mating retention element provided on the mounting cap.
