A damping adjuster is disclosed herein. The damping adjuster includes an adjuster housing and an adjuster shaft. The adjuster shaft rotatable within the adjuster housing, the adjuster shaft comprising a variable flow area feature, the variable flow area feature formed annularly about a portion of the adjuster shaft, the variable flow area feature comprising a plurality of different flow area values therealong. The damping adjuster also includes a fluid flow path through the adjuster housing, wherein the fluid flow path includes the variable flow area feature of the adjuster shaft.

A pressure balanced valve with integral pressure relief function is disclosed. The pressure relief valve includes a cap with an opening therein, a plunger configured to fill the opening in the cap, and a spring configured to hold the plunger against the cap. The pressure relief valve providing a fluid pathway through a piston, wherein the fluid pathway extends between a first fluid chamber and a second fluid chamber and provides a bypass for fluid to flow from the second fluid chamber to the first fluid chamber when a pressure of a fluid in the second fluid chamber is above a blow-off pressure of the pressure relief valve.

An integrated ride height system is provided wherein the system is configured couple to a vehicle. The system includes a coilover shock absorber and a hydraulic preload cylinder coupled to a shock body of the coilover shock absorber. The hydraulic preload cylinder engages an end of a coil spring of the coilover shock absorber. The system includes a reservoir coupled to the shock absorber allowing hydraulic fluid to flow between the reservoir and the coilover shock absorber. The system includes a reversible pump coupled between the hydraulic preload cylinder and the reservoir, wherein the pump operates to pump hydraulic fluid from the reservoir to the hydraulic preload cylinder to extend the hydraulic preload cylinder to increase ride height of the vehicle and operates to pump hydraulic fluid from the hydraulic preload cylinder to the reservoir to retract the hydraulic preload cylinder to decrease ride height of the vehicle.

A lever actuator is described that includes: a frame; a lever movably coupled to the frame, the lever comprising a contact portion; a multi-position track disposed in one of the lever and the frame, the multi-position track being continuous and comprising a plurality of ledges defining a plurality of discrete track positions; and a follower arm coupled to the frame and the lever by way of a track pin. The track pin is movable within the multi-position track. A force applied to the contact portion of the lever causes the track pin to advance among a respective one of the ledges to a subsequent discrete track position in a first direction.

Described are embodiments of rotatable link-based mounting systems for various dampers such as steering dampers. In one example, a steering damper includes a housing having a longitudinal centerline. The steering damper further includes a mounting system coupled to the housing. The mounting system includes at least two link members rotatably coupled to the housing. Longitudinal centerlines of the at least two link members intersect one another at a defined location on the longitudinal centerline of the housing to collectively create an instantaneous center of rotation for the housing at the defined location.

A suspension fork includes a lower tube, an upper tube telescopically engaged with the lower tube, and an air-spring assembly disposed within the lower tube and the upper tube. The air-spring assembly includes a positive air chamber, a negative air chamber, a piston dividing the positive air chamber and the negative air chamber, and a sealhead positioned proximate the negative air chamber. The sealhead includes an outer wall and an inner wall defining an aperture in which a shaft coupled to the piston is movably received. A hollow chamber is positioned between the outer wall and inner wall. A topout plate comprising a plurality of openings in communication with the hollow chamber is attached to the sealhead. The hollow chamber of the sealhead increases a volume of the negative air chamber, providing improved suspension performance.

A bumper carrier for a suspension fork includes a base plate and a retention feature. The retention feature may be configured to secure a bottom-out bumper to the bumper carrier. In some aspects, the retention feature comprises an annular wall integral with the base plate, which may at least partially nest the bottom-out bumper. The annular wall can define an annular notch surrounded by protrusions to retain the bottom-out bumper. The base plate may include apertures for coupling to a topcap. In some implementations, the bumper carrier includes at least one elastomeric portion permanently affixed to the base plate, which may be overmolded or adhesively bonded.

The present disclosure provides a suspension fork comprising a fork leg comprising an upper tube and a lower tube slidably engaged with one another for compression and rebound, a damper assembly positioned within the fork leg, the damper assembly comprising a shaft and a sealhead coupled to the shaft, and a reservoir configured to retain bath oil in proximity to the sealhead. The sealhead is sized and positioned to splash bath oil upwards when the sealhead is driven into the bath oil during the compression of the suspension fork. The sealhead comprises a base portion and a leading portion tapering downwards from the neck. The hydrodynamic profile of the sealhead creates controlled oil displacement patterns that distribute lubricating oil to internal components including bushings, seals, and sliding surfaces during suspension movement.

A suspension system includes an upper tube, a lower tube slidably engaged with the upper tube, and an air spring assembly disposed within the lower tube. The air spring assembly comprises an air piston positioned within a cylinder configured to retain an amount of bath oil, an air inlet positioned on a lower end of the cylinder, an extension tube in communication with the air inlet, and an air exit aperture positioned on the extension tube at a location above a maximum fill amount of the bath oil. The suspension system provides improved air spring performance and lubrication in an inverted fork configuration.

A suspension fork for a vehicle includes an upper tube and a lower tube slidably engaged with the upper tube collectively defining an interior. A topcap is positioned on the upper tube. A bottom-out assembly is disposed within the interior and comprises a bumper carrier positioned proximate to the topcap and an elastomeric bottom-out bumper affixed to the bumper carrier. An air pressure relief assembly can be integrated with the topcap. The suspension fork provides improved bottom-out protection and air pressure relief.
