A suspension travel control system (1046) for a vehicle suspension is disclosed. The suspension travel control system includes a stop post (834) secured to the vehicle frame and a suspension travel control formation that includes a base (1042) and a body (1048). The stop post (834) is positioned in a space defined by the body (1048). The suspension travel control formation may be secured to the axle, the main support member or incorporated into the axle coupling assembly to provide a rebound and jounce stop as well as longitudinal redundancy in the event of the failure or loss of a longitudinal linkage.

A spacer element system for a vehicle suspension system, includes a receiver configured to be attached to a suspension component of the vehicle suspension system, and a spacer that is removably connected to the receiver. A vehicle suspension system includes a spring and the spacer element system, wherein the receiver is attached to the spring.

A suspension system for a rear axle of a vehicle provided with a frame equipped with at least two side members, the suspension system connecting the axle to said side members and comprising a left side and a right side, each comprising an axle-holder assembly, a bellows, a leaf spring, first and second bars, and a torsion bar interposed between said left and right sides. The aforementioned elements of the suspension system being arranged to provide a functional layout having reduced costs and overall dimensions.

A Dual Air Spring Design for Applications with NarrowPackaging Envelope and High Load Requirements provides two, small-diameter air springs that can be retrofitted onto an existing vehicle frame to provide additional lift and suspension capabilities. The smaller size allows for the same lifting and suspension capabilities as a traditional, single air spring, but with easier and more compact installation, without impeding the factory bump-stops and easy integration with aftermarket lift blocks.

A primary air suspension system with the reliability of a secondary air suspension system by guaranteeing a minimum pressure in the air spring through a simple mechanical residual pressure valve. The residual pressure valve is set to the air spring pressure required to hold the rear of the unloaded pickup truck at the designed ride height if any of the components (compressor, tank, valves, air lines, Schrader valve, or electronic controller) failure.

A Retrofittable Air Suspension Brackets assembly comprises an air spring retained between an Upper Air Spring Mount and a Lower Air Spring Bracket. The Upper Air Spring Mount is attached to Upper Frame Brackets that are held in place by two U-Bolts, which also secure the Lower Air Spring Bracket and a Cradle Structure which limits movement of the vehicle frame member.

A leaf spring suspension is provided with an air spring to absorb a percentage of the load.

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 “Rolling Lobe” style of air spring with an extendable piston increases the overall travel of the air spring without increasing the compressed height of the spring.

Energy storing suspension components for use in suspension systems for wheeled vehicles and trailers, and suspension systems incorporating such energy storing suspension components are disclosed. The energy storing suspension components include an axle seat portion, a first end, and a first limb extending between the axle seat portion and the first end. The axle seat portion includes first and second surfaces with at least one of the first and second surfaces having at least two spaced apart recesses that are spaced from a center of the axle seat portion, the recesses being configured to receive respective protrusions extending from at least one suspension component that is connected to the energy storing suspension component when coupled within an axle coupling assembly.
