  • Patent number: 11685210
    Abstract: 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.

  • Patent number: 9545829
    Abstract: A dual-rate jounce bumper limits jounce travel between a first component and a second component of a vehicle. The second component is spaced from and moveable toward the first component along a jounce axis. The dual-rate jounce bumper includes a bumper and an outer member. The bumper has a first end for coupling to the first component and a second end spaced from the first end for contacting the second component as the second component moves along the jounce axis toward the first component. The bumper is compressible between the first and second components for limiting jounce travel. The bumper is also radially expandable as the bumper is compressed. The outer member is disposed about the bumper and is capable of limiting the radial expansion of the bumper as the bumper is compressed for increasing a stiffness of the bumper.

  • Patent number: 9428021
    Abstract: A jounce bumper is used in a suspension system of a vehicle. The jounce bumper comprises an outer member comprising a base portion and a sidewall extending from said base portion. The sidewall of the outer member is flexible relative to the base portion. The base portion and the sidewall define a cavity such that the outer member has a cup-shaped configuration. A bumper is at least partially seated within the cavity of the outer member. The bumper is compressible into the cavity of the outer member such that the bumper expands against the sidewall of the outer member, which forces the sidewall of the outer member to flex and expand radially outward. An isolation layer is disposed on the base of the outer member outside of the cavity and separates the outer member from either the strut assembly or the frame member.

  • Patent number: 7416175
    Abstract: A spring seat assembly for a suspension system of a vehicle utilizing a coil spring. The spring seat assembly includes a first spring seat retainer having a central axis. The first spring seat retainer includes a flange and a pocket portion extending from the flange toward a distal end. The flange includes a first side and a second side extending radially from the central axis in a spaced and parallel relationship. The flange includes a plurality of ribs that extend radially relative to the central axis. The ribs project axially from the first side and the second side of the flange and are spaced angularly from one another. The ribs on the first side are angularly offset from the ribs on the second side for dampening vibration and absorbing noise upon a compression of the coil spring.
