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.
