A bump stopper can be provided for a vehicle. The bump stopper includes an upper part, a lower part, and a connection member. The upper part and the lower part are stacked vertically and have double density. The connection member is positioned at an interface between the upper part and the lower part to connect the upper part and the lower part.

A jounce bumper can be dimensioned for securement along an end member of a gas spring assembly adjacent a sensing device. The jounce bumper can include a bumper body with a sensing passage extending their through such that the sensing device can communicate through the sensing passage. A gas spring assembly including a sensing device and such a jounce bumper as well as a suspension system including one or more of such gas spring assemblies are also included.

A bracket apparatus for a composite spring, may include a lower bracket disposed to come into contact with a composite spring when a U-bolt is fastened to a nut; an upper bracket disposed above the lower bracket so as not to be decoupled therefrom by the nut; and an elastic member disposed between the lower bracket and the upper bracket to provide a force such that the lower and upper brackets move away from each other.

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.

A spring device for a motor vehicle wheel suspension that includes a first leaf spring made of fiber-reinforced plastic and a second leaf spring made of fiber-reinforced plastic. The second leaf spring is shorter than the first leaf spring and together with the first leaf spring forms a V-shaped structure, which, in the region of the joined ends of the V-shape, has a first fastening device for the vehicle-body-side support and at the free ends of the V shape has a second fastening device on the first leaf spring for wheel-side support and a third fastening device on the second leaf spring for vehicle-body-side support.

An axle suspension for a vehicle includes a spring assembly with a leaf spring and a connecting arm, wherein the leaf spring supports a vehicle axle and, on an end side, is pivotably connected to a vehicle structure and pivotably connected to the connecting arm. In order to provide an optimized axle suspension with two-stage suspension, the spring assembly in a region of the connecting arm has a first stop element and the vehicle structure has a second stop element, which stop elements under normal load of the vehicle are spaced apart from one another and, when a limit load is exceeded, contact one another, whereby at least one stop element is elastically deformable.

A vehicle suspension having a frame attachment portion attached to a saddle, first and second bolster springs mounted to spring mounts on an outboard side of the saddle and mounted on walls of a spring mount on an outboard side of an equalizing beam, and third and fourth bolster springs mounted to walls of a spring mount on an inboard side of the saddle and mounted to spring mounts on an inboard side of the equalizing beam, wherein upwardly extending flanges on the bottom of the first and second bolster springs are mounted to each other using a common fastener, and wherein upwardly extending flanges on the bottom of the third and fourth bolster springs are mounted to each other with a common fastener.

There is provided a control arm comprising a shell-like shell of a first material and a reinforcement of a plastic material, wherein the reinforcement has a flex-element which protrudes therefrom and which can be supported or guided by means of a vehicle structure in order in the event of jounce and/or rebound of the suspension to produce a resilient action equivalent to a conventional spring.

A bracket apparatus for a composite spring, may include a lower bracket disposed to come into contact with a composite spring when a U-bolt is fastened to a nut; an upper bracket disposed above the lower bracket so as not to be decoupled therefrom by the nut; and an elastic member disposed between the lower bracket and the upper bracket to provide a force such that the lower and upper brackets move away from each other.

A vehicle suspension having a frame attachment portion attached to a saddle, first and second bolster springs mounted to spring mounts on an outboard side of the saddle and mounted on walls of a spring mount on an outboard side of an equalizing beam, and third and fourth bolster springs mounted to walls of a spring mount on an inboard side of the saddle and mounted to spring mounts on an inboard side of the equalizing beam, wherein upwardly extending flanges on the bottom of the first and second bolster sprints are mounted to each other using a common fastener, and wherein upwardly extending flanges on the bottom of the third and fourth bolster springs are mounted to each other with a common fastener.
