A gas spring and gas damper assembly (200) can include a gas spring and a gas damper. The gas spring can include a first end member, a second end member and a flexible wall that at least partially forms a spring chamber. The gas damper can include first and second damper elements (278, 280) as well as a damper element assembly that are telescopically interconnected with one another. The damper element assembly can include an outer side wall portion that at least partially defines a cavity and a biasing element extending into the cavity. A suspension system and a method of assembly are also included.

A suspension mount comprises an inner plate, an elastomer member, a lower case, and an upper plate. A plate includes an extended portion extending from the circular-cylinder portion. An incline portion is integrally formed on the extended portion and clamped by the elastomer member. The elastomer member clamps the incline portion of the extended portion from the outer periphery side. Thereby, when the plate is fixed in a status that the plate and the elastomer member are contained in the case, the input in the axial direction of the mount will be decomposed into a compressive load in an axial direction and a compressive load in an axially-perpendicular direction by the incline portion. Therefore, the elastomer member is held in a status that it is precompressed in the axial direction and the axially-perpendicular direction.

A wheelchair suspension comprises a frame, at least one pivot arm, at least one front caster, at least one rear caster, a stabilizing system, and a sensor. The pivot arm is coupled to the frame. The front caster is coupled to the pivot arm. The rear caster is coupled to the frame. The stabilizing system is coupled to the frame and the pivot arm. The sensor is arranged such that movement of the frame relative to the rear castor causes actuation of the stabilizing system to at least partially resist further movement of the frame.
摘要:
Suspension system for a vehicle is disclosed and claimed. The suspension system includes a fluid, a suspension strut, a hydraulic cavity, an accumulator, and a volume modulator. The hydraulic cavity is at least partially defined by the suspension strut and is adapted to contain a portion of the fluid. The hydraulic cavity supplies a suspending spring force that biases a wheel of a vehicle toward the road surface. The volume modulator selectively pushes the compressible fluid into the hydraulic cavity and vents the compressible fluid from the hydraulic cavity, thereby actively modulating the suspending spring force.

A controlled equilibrium device comprising a housing; at least one spring, each at least one spring having a spring stiffness; and a load leveling device movable through the housing between a first maximum displacement position and a second maximum displacement position, the load leveling device comprising a deadband displacement zone defined between a first deadband displacement threshold and a second deadband displacement threshold, the displacement required to reach the first and second deadband displacement thresholds being less than the displacement distances required to reach the first and second maximum displacement positions, the at least one spring stiffness being substantially constant when the displacement of the load leveling device is within the deadband zone, the stiffness of the at least one spring being modified to a second stiffness when the load leveling device is equal to or beyond either the first deadband displacement threshold or the second deadband displacement threshold.
摘要:
A suspension system for a vehicle having left and right wheels is disclosed and claimed. The system includes first and second suspension struts and first and second hydraulic cavities to supply first and second suspending spring force for the left and right wheels, respectively. The system also includes a volume modulator to selectively push fluid into and vent fluid from the first and second hydraulic cavities, thereby actively modulating the first and second suspending spring forces. The volume modulator includes first and second modulator pistons and first and second cavity-side valves. In a preferred embodiment, the modulator pistons are cycled and the cavity-side valves are opened and closed to counteract roll of the vehicle. Further, in a preferred embodiment, the first modulator piston and the second modulator piston are located approximately 180null apart relative to an eccentric to minimize power consumption of the volume modulator during roll of the vehicle.
摘要:
A suspension device for a vehicle wherein a telescopic damper, having a cylinder and a piston carried by a piston rod emerging through a seal at one end of the cylinder, is laterally surrounded by a deformable enclosure which can be supplied with fluid at an adjustable pressure, whereby at least partly to support the weight of the vehicle, the wall of the deformable enclosure being arranged to isolate the supplied fluid from the seal through which the piston rod emerges from the cylinder.
