A hydraulic damper comprises a main tube, a piston assembly, a base valve assembly, and a compression stop assembly. The compression stop assembly includes an insert defining an inner chamber, and a sleeve displaceable along with the main piston assembly and configured to be slidably introduced inside the inner chamber. The sleeve has a diameter lower than the diameter of the main tube defining a first external flow channel between the sleeve and the main tube; the sleeve is attached to the piston assembly by a spring disposed within the sleeve; and the insert is provided with a plurality of axially-spaced holes and has an annular flange adjoining the inner wall of the main tube and separating the compression chamber from a second external flow channel between the radially external outlets of the holes and the base valve assembly.

A leaf spring vehicle suspension system includes a chassis rail and an axle. The suspension system also includes a first stage leaf spring. The suspension system further includes a second stage leaf spring. The suspension system yet further includes a third stage leaf spring operatively coupled at a first end and a second end to the chassis rail, wherein the first stage leaf spring is located below the third stage leaf spring and the second stage leaf spring is located below the first stage leaf spring. The suspension system also include a spacer in abutment with a leaf spring, wherein the spacer is formed of at least one composite material.

The present disclosure discloses an all-terrain vehicle which includes: a frame, a left-front suspension assembly connected with a left side of the frame and including a left-upper rocker arm and a left-lower rocker arm, the left-upper rocker arm is located above the left-lower rocker arm; a right-front suspension assembly connected with a right side of the frame and including a right-upper rocker arm and a right-lower rocker arm, the right-upper rocker arm is located above the right-lower rocker arm; a lateral stabilizer bar mounted on the frame and arranged above the left-upper rocker arm and the right-upper rocker arm, and a steering gear mounted on the frame and located below the lateral stabilizer bar.

An agricultural vehicle suspension may comprise a spring and a first spindle operably coupled with the spring in a spindle axial direction. A stop body may be operably coupled to the first spindle in a cylinder axial direction. The stop body may be configured to limit an axial length of travel of the suspension relative to the first spindle. The first spindle may be a steering spindle or a suspension spindle.

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.

An electric height control device may include: an oil storage part configured to store oil therein; a motor driving part inserted into the oil storage part and driven when power is applied thereto; a hydraulic block part coupled to the motor driving part, connected to the oil storage part, and configured to amplify oil; and a control part coupled to the hydraulic block part, and configured to control the motor driving part and the hydraulic block part.

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 top mount assembly including a housing for being connected to the frame of the vehicle. A rod connection assembly is disposed in the housing for being attached to a piston rod of the damper assembly. A chamber is defined between the rod connection assembly and the housing for receiving a fluid. A resilient member is disposed between the rod connection assembly and the housing. A partition assembly is positioned between the resilient member and the housing and axially divides the chamber into an upper chamber region and a lower chamber region. The partition assembly defines at least one passage that extends between the upper chamber region and the lower chamber region. At least one electromagnetic coil is disposed adjacent to the passage for selectively modifying the characteristics of the fluid passing through the passage to modify the damping characteristics of the top mount assembly.

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 bumper rubber for a shock absorber includes: a body portion in which a cylindrical coupling hole vertically penetrates such that a piston rod is connected thereto; one or more inner grooves formed concavely along a circumferential direction of the coupling hole and arranged in a vertical direction; and an inner protrusion protruding from an inner peripheral surface of the inner groove radially inward, wherein a laterally protruding end of the inner protrusion comes into close contact with an outer surface of the piston rod when the body portion is vertically compressed.
