Suspension system of a vehicle and a shock absorber assembly of the suspension system, the shock absorber assembly includes a top mount and a jounce bumper. The jounce bumper includes a main body made of an elastic material, such as a foam elastomer or rubber and a fixing element made of a second harder material. The fixing element has a wall portion that extends around the outermost upper part of the main body and at least one elastic retaining area cooperating with a respective protuberance arranged in the top mount to fix the jounce bumper to the top mount. Between the outermost upper part of the main body and the fixing element there is a gap that enables the main body to expand radially also in the area covered by the wall portion of the fixing element when the main body is compressed during use.

A bearing structure component for a vehicle bearing, having at least one through-opening for receiving a connecting element or a bearing which is made of foamed synthetic material, and the foamed synthetic material forms an integral foam structure. In an embodiment, at least one first local section of the integral foam structure has a wall thickness of greater than 4 mm.

A dual rate jounce bumper and a vehicle containing the dual rate jounce bumper are useful.

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.

A trailer frame including an axle section having two spaced longitudinal frame members connected by at least one cross member, the longitudinal frame members each having a first end and a second end; a rear section attachable to the axle section; and a dimple assemble joining the axle section to the rear section, the dimple assembly including a dimple pattern formed on each frame member of the axle assembly, the dimple pattern on the axle assembly defining a first dimple axis, and a dimple pattern formed on one end of the rear section and nestable within the dimple pattern formed on the axle section, the dimple pattern on the rear section defining a second dimple axis offset relative to the first dimple axis to create a camber between the axle section and the rear section when the first dimple is nested within the second dimple pattern.

A spring aid assembly for a vehicle suspension system. The spring aid assembly includes: a housing having a generally cylindrical cavity formed therein, a damper including a rod extending through a cap, and a spring aid having a proximal end retained within the cavity of the housing, a distal end extending in an axial direction away from the housing, and an outer circumferential groove formed therein. The cavity in the housing is bounded by a generally cylindrical inner peripheral wall that has a plurality of axially and radially extending projections extending therefrom. A ring is positioned in the outer circumferential groove of the spring aid. The ring provides a positive stop to the spring aid assembly and prevents the cap of the damper from coming into direct contact with the housing during full compression of the damper.

Provided is a trailing arm riding mower suspension system that includes trailing arms adapted to support hydraulic motor units and having leading ends pivotally coupled to a mower frame by way of leading end spherical joints and trailing ends having hydraulic drive unit mounts, where the trailing arms are adapted to pivot about leading end pivot locations defined by the leading end spherical joints.

A vehicle suspension system may include a first suspension assembly operably coupling a first wheel to a chassis of a vehicle, a second suspension assembly operably coupling a second wheel to the chassis where the first and second wheels form a pair of front wheels, a third suspension assembly operably coupling a third wheel to the chassis, a fourth suspension assembly operably coupling a fourth wheel to the chassis where the third and fourth wheels forming a first pair of rear wheels, and a payload extension kit that is attachable to the chassis non-permanently. The payload extension kit may include a fifth suspension assembly operably coupling a fifth wheel to a sub-frame extension of the payload extension kit, and a sixth suspension assembly operably coupling a sixth wheel to the sub-frame extension, where the fifth and sixth wheels form a second pair of rear wheels.

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.

A pressure buffer stop for a vibration damper that comprises for being at least partially received in a dome bearing housing an outer contour and for coaxial arrangement on a piston rod of the vibration damper a hollow-cylindrical basic structure with an inner contour, wherein the outer contour of the pressure buffer stop comprises in at least one region for being at least partially received in the dome bearing housing a three-dimensionally structured surface.
