A shock absorber device for a motor vehicle includes a spring support, a spring, a damping device configured to exert a damping force, a control unit, an electric motor electrically connected to the control unit and controllable by the control unit through a power supply signal emitted by the control unit, such that the electric motor provides a torque or a force corresponding to the power supply signal, and conversion means configured to control the damping device turning the torque or force outputted into a further force corresponding to the torque or force outputted and exerted by means of the damping device, wherein the control unit is configured to receive a first control signal indicative of a target value for the further force and to provide the power supply signal as a function of the first control signal, such that the power supply signal corresponds to the target value for the further force, the control unit being coupled to the spring support in a fixed position relative to the spring support.

A suspension element includes a main body having an end cap defining an internal volume and a tubular element slidably engaged with the main body. The suspension element further includes a first piston and a flow control element. The flow control element is configured to prevent movement of the tubular element relative the main body in a direction. The suspension element may further include a locking member and a piston. The locking member may be configured to engage a barrier of the main body when the first piston traverses at least a predetermined distance towards the end cap. The locking member may be affixed to the tubular element and may fully surround the tubular element. Together the flow control element and the locking member are configured to prevent movement of the suspension element.

A passive lockable strut is presented. The passive lockable strut comprises a first end; a second end; a fluid chamber between and connected to the first end and the second end; and a fluid within the fluid chamber, wherein the fluid is configured to activate the passive lockable strut to place the passive lockable strut in a locked condition in response to a change in an operating condition applied to the passive lockable strut.

A method and apparatus for a suspension comprising a spring having a threaded member at a first end for providing axial movement to the spring as the spring is rotated and the threaded member moves relative to a second component. In one embodiment, the system includes a damper for metering fluid through a piston and a rotatable spring member coaxially disposed around the damper and rotatable relative to the damper.

A vehicle suspension damper comprises a cylinder and a piston assembly including a damping piston along with working fluid within the cylinder. A bypass permits fluid to avoid dampening resistance of the damping piston. A fluid path through the bypass is controlled by a valve that is shifted by a piston surface when the contents of at least one predetermined volume is injected against the piston surface which acts upon the valve. In one embodiment, the bypass is remotely operable.

A door component has a controllable damping device containing a magnetorheological fluid as a working fluid. Two connection units can move relative to one another. One of the two connection units can be connected to a support structure and the other of the two connection units can be connected to a moveable door unit of a vehicle in order to damp a movement of the door unit between a closed position and an open position under control of a control device. The damping device has an electrically adjustable magnetorheological damping valve which is current-less in an adjusted state of the damping valve. A damping property of the damping device is continuously adjusted as needed via an electrical adjustment of the damping valve.
