A spring for a suspension is described. The spring includes: a spring chamber divided into at least a primary portion and a secondary portion, and a fluid flow path coupled with and between the primary portion and the secondary portion. The fluid flow path includes a bypass mechanism, wherein the bypass mechanism is configured for automatically providing resistance within the fluid flow path in response to a compressed condition of the suspension.

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 high-pressure gas spring for vehicle suspension systems includes an integral gas damping system and an integral counter spring to reduce spring residual force at suspension rebound. The gas spring includes an inverted piston feature that reduces the overall length of the device. Additionally, there are other innovative features incorporated in the gas spring to improve performance, reduce cost and minimise weight.

An air spring strut assembly includes a top cap with a metal flange overmolded within a plastic overmold housing. The metal flange carries structural loads through the top cap and the plastic overmold housing includes non-load bearing complex shapes ands surfaces. A shock absorber and bellows are attached to the top cap to complete the air spring strut assembly.

A damper assembly has a longitudinal axis and includes a damper housing with a side wall portion and an end wall portion defining a damping chamber containing a quantity of damping fluid. A photon source and a photon receptor are operatively disposed in optical communication with the non-gaseous damping fluid in the damping chamber. The photon source is operable to direct a photon through the non-gaseous damping fluid toward an associated target surface. The photon receptor is operable to receive the photon reflected off the associated target surface through the non-gaseous damping fluid. A sensor suitable for such use as well as spring and damper assemblies and suspension systems are also included.
