摘要： A support ring for a resiliently deformable jounce bumper is made of a cast material. The support ring contains an inner circumferential surface that defines a through-opening extending along a longitudinal axis, an outer circumferential surface, a first axial end face, an opposing second axial end face, and a plurality of recesses configured to reduce the material mass which the support ring is made of. The through-opening is configured to fit around the jounce bumper. The plurality of recesses may be formed in at least one of the two end faces such that the recesses extend from the respective end face in the axial direction into the material of the support ring.

摘要： A jounce bumper assembly can be used in a suspension system for an automotive vehicle. The assembly can contain a jounce bumper having a longitudinal axis, a bottom portion, and a tip portion spaced apart from the bottom portion in the axial direction, where the jounce bumper is resiliently deformable between an uncompressed basic state and an axially compressed state. The assembly can also contain a support member for supporting the jounce bumper, the support member having a wall section which can be arranged around the bottom portion and resiliently deformable with the jounce bumper in the axial and radial direction. The assembly can further contain at least one stiffening element associated to the wall section and configured to locally limit the radial deformation of the support member.

摘要： 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.

摘要： A spring element, in particular a jounce bumper, for a vehicle shock absorber contains a longitudinal axis, a base body having a length along the longitudinal axis, and an end portion configured for contact against a damper cap of the vehicle shock absorber. 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 contact surface that is wound along a helix around the longitudinal axis.

摘要： The present invention relates to a composite element, especially for a damping element, comprising a) at least one metallic body having a surface; b) a coating comprising an epoxy resin on at least part of the surface of the metallic body; c) a plastics body comprising at least one polyurethane, which at least partly surrounds the metallic body of (a) and in the region of the surround is at least partly in direct contact with the coating of (b), wherein the composite element between the surface of the metallic body (a) and the coating (b) has a conversion layer (d) which comprises at least one compound selected from the group of zirconium(IV) oxide, zinc(II) phosphate, and chromate. The invention further relates to a damping element comprising the composite element and at least one further body which is at least partly in direct contact with the composite element, preferably with the plastics body of (c). The invention additionally relates to production processes for composite element and damping element, to the composite and damping elements, respectively, that are produced or producible by these processes, and the use of these composite and damping elements, respectively.

摘要： A process can be used for producing a thermoplastic polyurethane, where the process at least involves converting at least one isocyanate composition and a polyol composition, to obtain a prepolymer having isocyanate groups, and reacting the resulting prepolymer with at least one chain extender. The at least one isocyanate composition contains an isocyanate selected from naphthylene 1,5-diisocyanate (NDI), diphenylmethane 4,4′-diisocyanate (MDI), p-phenyl diisocyanate (PPDI), o-tolidine diisocyanate (TODI), ethylene diphenyl diisocyanate (EDI), or mixtures thereof. The polyol composition contains a polytetrahydrofuran or a derivative thereof. A thermoplastic polyurethane obtained or obtainable by such a process is useful, and a foamed pellet material can be produced containing such a thermoplastic polyurethane. The foamed pellet material of the invention can be used for production of a molded article.

摘要： A shock absorber arrangement for a vehicle suspension contains a shock absorber having a damper cap and a piston rod, and a supplementary spring which is arranged on the piston rod opposite the shock absorber and has an outer surface facing the damper cap and an inner surface facing the piston rod, and is configured for damping the movement of the shock absorber in the direction of the piston rod on contact with the damper cap. The outer surface and/or the inner surface is at least partially coated with a lubricant.

摘要： A spring element, in particular a jounce bumper, for a vehicle shock absorber contains a longitudinal axis, a base body extending along the longitudinal axis, and an end portion configured for contact against a damper cap of the vehicle shock absorber. 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 at least three projections that are spaced apart from one another in a circumferential direction, and protrude from the base body in the direction of the longitudinal axis. Each of the projections has a distinct length in the direction of the longitudinal axis, and the projections are arranged along the circumference of the end portion such that the lengths of the projections increase monotonously in the circumferential direction.
