A shock absorber includes: a damper tube accommodating a piston in a reciprocally movable manner; a suspension spring for urging the damper tube and a piston rod in opposite directions; a first male screw provided on an outer peripheral surface of the damper tube; a first nut screwed into the first male screw so as to enable a spring load of the suspension spring to be adjusted; a second nut screwed into the first male screw so as to enable a position of the first nut in an axial direction of the damper tube to be fixed; a second male screw having a reverse screw configuration to the first male screw and provided on the outer peripheral surface of the damper tube; and a damper head screwed into the second male screw so as to enable the damper head to cover one end portion of the damper tube.

A vehicle weight measurement device includes a diaphragm which covers an opening area of a groove portion of a mounting part to form an oil chamber of a predetermined space together with the groove portion; a pressure sensor which detects a change in pressure of measurement fluid in the oil chamber; a first piston which presses the diaphragm; a second piston which presses the first piston; and a bearing unit interposed between the second piston and a spring bush which receives one end of a spring of a suspension device and is relatively rotatable. The bearing unit includes a thrust needle bearing which swingably supports a load in a longitudinal direction of the suspension device, and a slide bush which does not receive a load in the longitudinal direction and receives a load in a radial direction while causing constant damping to swinging.

A damper assembly for a vehicle which includes a damper body, a first ring element, and a spring coupler. The damper body includes a threaded portion which extends between a first end and a second end of the damper body. The first ring element is disposed within a first groove in the threaded portion. The spring coupler having a passage to concentrically receive the damper body such that the spring coupler is configured to slide over the first ring element. The first ring element is disposed within the first groove of the threaded portion such that a sliding clearance is provided between an inner portion of the spring coupler and the threaded portion.

A vehicle suspension device, including : a carrier; a lower arm and an upper arm each of which is pivotally supported at one end portion thereof by a vehicle body, the other end portion of each of the lower arm and the upper arm being connected to the carrier; a rocking lever supported at one end portion thereof by the vehicle body so as to be rockable; a link one end portion of which is connected to the rocking lever and the other end portion of which is connected to one of the lower arm and the upper arm at a position between the one end portion and the other end portion of the one of the lower arm and the upper arm; and a shock absorber pivotally supported at one end portion thereof by the vehicle body, the other end portion thereof being connected to the rocking lever.

A suspension includes a coil spring, a shock absorber, a spring seat, and at least three strongly pressing parts. The coil spring elastically receives vertical movement of a wheel relative to a vehicle body. The shock absorber damps the vertical movement. The spring seat is provided in the shock absorber. The sprint seat supports an axial end of the coil spring. The coil spring is in direct or indirect contact with the spring seat over a predetermined distance from an end to a point of separation of the coil spring. The strongly pressing parts are provided in the spring seat. The strongly pressing parts apply contact pressures higher than contact pressure applied by other part, to the coil spring. The point of separation is disposed at a region that is between the strongly pressing parts and has the largest opening angle about an axial center of the shock absorber.

The invention relates to a top mount assembly of a suspension strut, the assembly comprising: a bearing and a filtering sub-assembly abutting the bearing, which includes: a filter block; a lower support having a central portion abutting a lower face of the filter block and a peripheral portion; a cover including a central portion abutting an upper face of the filter block and a peripheral portion abutting the annular peripheral portion of the lower support. The peripheral portion of the cover is provided with fastening openings arranged radially outside the bearing to secure the filtering sub-assembly to a body element of the vehicle.

An off-road vehicle includes a frame, a front suspension, and a rear suspension. In some examples of the off-road vehicle, the rear suspension includes trailing arms with are pivotally attached to the frame rearward of an operator area. Further, the frame can include a front subframe assembly and a rear subframe assembly which are easily removable from the main frame of the vehicle to permit access to various components of the off-road vehicle.

A device for damping vibrations may comprise a hollow damper tube, a piston rod with a piston fastened thereto, at least one spring plate, and at least one securing element. The piston may be disposed within the damper tube, and the spring plate may be disposed outside the damper tube. To achieve a reliable connection between the spring plate and the damper tube in a cost-effective manner, the spring plate may be connected to the damper tube in both a force-fitting manner and a form-fitting manner. The present disclosure further concerns motor vehicles that employ such devices, as well as methods for fastening spring plates to damper tubes.

A coilover shock absorber includes a damper element and a coil spring, where the coilover shock absorber includes a first mount for the damper element and a second mount for the damper element, and where the coilover shock absorber includes a first seat for the coil spring and a second seat for the coil spring, where the first mount for the damper element is operatively separate from the first seat for the coil spring, where the second mount for the damper element is operatively separate from the second seat for the coil spring. The resulting inverted coilover shock absorber allows for separate load paths for the damper element and the coil spring to the chassis.

An outdoor power equipment unit includes a front wheel independent suspension system. The front wheel independent suspension system includes a frame, a first front wheel assembly, a second front wheel assembly, a first laterally-extending suspension arm pair, and a second laterally-extending suspension arm pair. The first laterally-extending suspension arm pair includes a first suspension arm and a second suspension arm, both coupled to the frame and the first front wheel assembly. The second laterally-extending suspension arm pair includes a third suspension arm and a fourth suspension arm, both coupled to the frame and the second front wheel assembly. Both the first suspension arm pair and the second suspension arm pair are configured to independently pivot about the frame such that each of the first front wheel assembly and the second front wheel assembly are vertically displaceable relative to the frame.
