摘要： A fluid suspension system for a land vehicle is provided with an actuator connected to a chassis and an axle of a land vehicle spaced apart from a pivotal connection of the axle. A fluid pressure circuit is in cooperation with the at least one actuator. A controller is in operable communication with the fluid pressure circuit and is programmed to receive input indicative of a travel speed of the land vehicle. The fluid pressure circuit is adjusted to limit fluid flow rate or reduce fluid pressure at a low speed travel range to permit the axle to pivot in response to variations in an underlying support surface. The fluid pressure circuit is adjusted at a higher speed travel range for selective actuation of the at least one actuator or for a higher fluid pressure actuation of the at least one actuator, in response to variations in the underlying surface.

摘要： 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 tipping of the frame causes actuation of the stabilizing system to at least partially resist further movement of the frame.

摘要： There is provided an air spring for supporting a load, the air spring comprises a chamber for holding a pressurized gas in use, a load-bearing surface arranged to transmit a force from a load in use to the pressurized gas held in the chamber. Importantly, in order to lower the spring rate, the chamber contains a mass of adsorptive material. There is also provided a use of an adsorptive material for the purpose of lowering the spring rate of an air spring, including a gas strut and a pneumatic wheel. There is also provided a method of designing an air spring using an adsorptive material to lower the spring rate.

摘要： A hydraulic actuator includes a shock absorber and a control system that is separate from the shock absorber and which generates damping loads for the hydraulic actuator. The control system generates the damping load by using a pair of variable valves, a pair of check valves, an accumulator, a pump/motor and a flow controller. The forces are generated in all four quadrants of compression/rebound and active/passive. A device which recuperates the energy generated by the hydraulic actuator can be incorporated into the hydraulic actuator to generate energy in the form of electrical energy.

摘要： The working clearance height of a high-clearance vehicle is normally established by four main suspension spindles that are respectively received for reciprocating within upright journals provided at the opposite ends of front and rear axle assemblies of the vehicle main frame, with the bottom end each of the main spindles being received in a bore at the top of an associated wheel motor housing that serves also as a wheel hub mounting bracket. In order to increase the working clearance height of the vehicle, an optional elongate spacer assembly is mounted between the bottom of each elongate main suspension spindle and the associated wheel motor housing. Each main suspension spindle is inclined slightly outwardly relative to a vertical plane extending in the direction of travel of the vehicle and, in order for the spacing between tires at opposite sides of the vehicle to remain the same, with or without the usage of the spacer assemblies, each spacer assembly includes a coupler spindle extending parallel to, and offset inwardly from, a pivot axis of the associated main suspension spindle by a distance calculated to result in the desired tire spacing, this coupler spindle being received in the bore at the top of the associated wheel motor housing.

摘要： A vehicle independent suspension has a plurality of wheel-control links, with an upper link being a transverse or diagonal link and with the surface spanned by the joint points of the upper transverse or diagonal link intersecting, at least in regions, a gas or hydropneumatic spring arrangement which suspends the wheel. The gas or hydropneumatic spring arrangement has a bellows which is arranged between a dimensionally rigid head plate arranged on the vehicle body and a rolling piston. Vehicle-body-side joints of the upper transverse or diagonal link are supported on the head plate.

摘要： Suspension system for a vehicle is disclosed and claimed. The suspension system includes a compressible fluid, a suspension strut, a hydraulic cavity, a reservoir, 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 compressible fluid. The hydraulic cavity and the compressible fluid supply 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.
