A floor assembly includes a controller, a compressor, an airbag, and a floor. The controller is configured to provide one or more user controls to permit a user to operate the compressor and regulate pressure in the airbags. The floating floor is configured to isolate a carrying load from vibrational effects and trailer forces. The assembly is optionally removable from a trailer floor and may be inserted on a different trailer. A guide member is used to restrict movement of the floor on the airbags to only a vertical motion. The guide members may include a dampener.

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.

A suspension arrangement for a vehicle includes a piston for supporting a flexible bellows assembly of the suspension arrangement, said piston having a first portion connectable to the flexible bellows assembly and a second portion connectable to a wheel axle, said piston further having an outer side and an inner side, and wherein said suspension arrangement further comprises a mounting structure for positioning an insertable sensor device toward the flexible bellows assembly, said mounting structure extending at least from the outer side to the inner side and having an outer opening for receiving the insertable sensor device from an outside of the piston.

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.

An air-suspension module for a rigid axle including an air-bellows mount and an air-bellows module supported on the air-bellows mount in the operational state of the air-suspension module, the air-bellows module having an air-suspension bellows designed to change its shape and a supporting body connected to the air-suspension bellows, one of the components of the air-bellows mount and the supporting body having a coupling projection protruding along a virtual projection path, which engages with a coupling recess formed at the respectively other component along the projection path, a translatory relative movement of the supporting body being physically limited relative to the air-bellows mount, orthogonally with respect to the projection path and in a direction along the projection path; one of the components of the air-bellows mount and the supporting body having a latching body and the respectively other component of the air-bellows mount and the supporting body having a latching recess such that the latching body is in a form-locking latching engagement with the latching recess, so that a translatory relative movement of the supporting body relative to the air-bellows mount is physically limited in the two opposite directions along the projection path.

Assembly in a compressed air system of a vehicle provided with an air ride suspension, the assembly being configured to lift the vehicle body by filling at least one air spring, the solenoid valves being switchable in cooperation with an electronic control device, and the assembly including a pressure line for filling the air springs, and the pressure line including a first branch line connectable to the pressure line via a pilot-controlled solenoid valve for filling the air springs and including first supply pipes and pilot-controlled solenoid valves for each air spring as well as a second branch line for providing a control pressure which includes second supply pipes for the pilot-controlled solenoid valves, wherein the second branch line is connected to the pressure line via a check valve, the check valve providing a block position against venting or pressure drop in the second branch line.

A gas spring for use in a gas suspension system. The gas spring includes a gas inlet port configured to receive compressed gas and a gas inlet chamber connected via an inlet conduit to the gas inlet port and via an opening to an internal volume of the gas spring. The inlet conduit is connected to the gas inlet chamber at a position offset from a central axis of the gas inlet chamber such that an angle between a longitudinal axis of the gas inlet port and a surface of an interior wall of the gas inlet chamber opposing the gas inlet port is acute.

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 vehicle includes a first actuator, one or more second actuators, and an electronic control unit. The first actuator is configured to control a stroke of a suspension for a control target wheel. The one or more second actuators is configured to control the stroke of the suspension and more responsive than the first actuator. The electronic control unit is configured to: execute a calculation process to calculate a required control amount for at least one of roll control and pitch control of the vehicle; and execute a command process to distribute and command the required control amount to the first actuator and the one or more second actuators.
