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.
Claims19
A spring element, comprising:
- a longitudinal axis and a base body extending along the longitudinal axis, the base body being 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, and
- an end portion configured for being brought into contact with a vehicle part moving relatively to the spring element;
- wherein the end portion comprises a circumferential outer surface and at least one recess in the circumferential outer surface, said at least one recess extending inwards and defining a hollow space in the base body,
- wherein the end portion comprises an end face, and the at least one recess is spaced apart from the end face in the direction of the longitudinal axis,
- wherein the end face, in the uncompressed basic state of the base body, comprises a substantially planar surface and is oriented perpendicular to the longitudinal axis, and the at least one recess is configured to collapse to allow the end face to assume a concave shape,
- wherein the at least one recess extends all the way through the base body.

A spring element, comprising:
- a longitudinal axis and a base body extending along the longitudinal axis, the base body being 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, and
- an end portion configured for being brought into contact with a vehicle part moving relatively to the spring element;
- wherein the end portion comprises a circumferential outer surface and at least one recess in the circumferential outer surface, said at least one recess extending inwards and defining a hollow space in the base body,
- wherein the end portion comprises an end face, and the at least one recess is spaced apart from the end face in the direction of the longitudinal axis,
- wherein the end face, in the uncompressed basic state of the base body, comprises a substantially planar surface and is oriented perpendicular to the longitudinal axis, and the at least one recess is configured to collapse to allow the end face to assume a concave shape,
- wherein the at least one recess in the circumferential outer surface has an oblong cross section in a plane parallel to the longitudinal axis, and
- wherein said oblong cross section is defined by a lateral width in a direction perpendicular to the longitudinal axis and an axial width in the direction of the longitudinal axis, and wherein the lateral width is greater than the axial width.
