A vehicle suspension damper is described. The vehicle suspension damper includes: a pilot valve assembly; a primary valve; and an adjuster, wherein the pilot valve assembly meters fluid to the primary valve, and the adjuster moves the primary valve.

A motion control system includes a top mount, a bottom mount, a rigid housing, an air spring, and a linear actuator. The air spring transfers force of a first load path between the top mount and the bottom mount. The air spring includes a pressurized cavity containing pressurized gas that transfers the force of the first load path. The linear actuator transfers force of a second load path between the top mount and the bottom mount in parallel to the first load path. The rigid housing defines at least part of the pressurized cavity and transfers the force of the second load path.

A vehicle corner system for a dual-axle wheels assembly may include: a sub-frame; a first wheel interface having a first spinning axis about which a first wheel spins when connected to the first wheel interface; a first suspension linkage connected to and being transverse to the first wheel interface and to the sub-frame; a second wheel interface having a second spinning axis about which a second wheel spins when connected to the second wheel interface; a second suspension linkage connected to and being transverse to the second wheel interface and to the sub-frame; and a motion restrainer comprising a spring interconnecting the first suspension linkage and the second suspension linkage.

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 control system includes: a first electric current setting unit configured to set a first electric current based on an actual damping speed; a second electric current setting unit configured to set a second electric current based on a model damping speed; a weight coefficient setting unit configured to set a weight coefficient based on the actual damping speed; and a target electric current setting unit configured to set a sum of a first value and a second value as a target electric current of the damper, the first value being obtained by multiplying the second electric current by the weight coefficient, the second value being obtained by multiplying the first electric current by a value obtained by subtracting the weight coefficient from one. The first electric current setting unit is configured to make the first electric current smaller than the second electric current in a prescribed case.

A vehicle corner system for a dual-axle wheels assembly may include: a sub-frame; a first wheel interface having a first spinning axis about which a first wheel spins when connected to the first wheel interface; a first suspension linkage connected to and being transverse to the first wheel interface and to the sub-frame; a second wheel interface having a second spinning axis about which a second wheel spins when connected to the second wheel interface; a second suspension linkage connected to and being transverse to the second wheel interface and to the sub-frame; and a motion restrainer comprising a spring interconnecting the first suspension linkage and the second suspension linkage.

Pressure-sensitive vales are incorporated within a dampening system to permit user-adjustable tuning of a shock absorber. In one embodiment, a pressure-sensitive valve includes an isolated gas chamber having a pressure therein that is settable by a user.

A device for connecting the elastic elements and dissipaters of variable type of a mechanical suspension interposed between two vibrating or tilting mechanical systems, the source body and the receiving body, respectively, in order to reduce the forces acting on the receiving body, and/or the displacement thereof, and/or the speed thereof, or combinations of the previous physical magnitudes and/or of any other ones, which are produced on the receiving body due to the motion or forces to which the source is subjected. The device consists of elastic elements, such as metal components or compressed gases, energy dissipating elements, either by means of friction between fluid and solid, and between solid and solid, or by means of suitable electromagnetic couplings the damping ability of which can be automatically varied by a suitable control system according to the operating conditions of the suspension; elements forming the kinematic connection structure between the elastic elements, damping elements, source and receiving bodies, such connections being solid or fluid or electromagnetic connections.

A suspension control apparatus includes a damping force adjustable shock absorber disposed between a vehicle body and a wheel of a vehicle and capable of adjusting a damping force to be generated, a vertical movement detection device configured to detect a state regarding a vertical movement of a vehicle, and a controller including: a target damping force calculation section configured to calculate a target damping force based on a detection result of the vertical movement detection device, a correction section configured to calculate a corrected damping force, which is acquired by reducing the target damping force when a relative speed is a low speed between a sprung side and an unsprung side of the damping force adjustable shock absorber, and a control signal output section configured to output the control signal corresponding to the corrected damping force to the damping force adjustable shock absorber.
