An adjustable shock absorber system includes: a coil over shock absorber with a spring and a lockable adjustment ring; a protective cover assembly, optionally including top and bottom cover portions; a shock adjuster tool with a lever arm and a tool grip portion, including a band assembly, and a tool attachment assembly, including a connector member and a tool member; such that the tool grip portion detachably connects to the peripheral mounting surface of the lockable adjustment ring; whereby the shock adjuster tool can be used to adjust a preload of the coil-over shock absorber. Alternatively, an adjustable shock absorber system includes: a coil-over shock absorber with a spring and an adjustment ring; an adjustment ring assembly, which detachably interlocks with the adjustment ring; and a shock adjuster tool with a lever arm and a tool grip portion, which detachably connects with the adjustment ring assembly.

An actuator whose total length can be reduced is provided. An actuator (2) includes: a casing (7); a hollow shaft (8) rotatably supported by the casing (7) via a bearing (9a, 9b), the hollow shaft (8) including a bottom portion (8b); a screw shaft (14) coupled to the bottom portion (8b) of the hollow shaft (8), the screw shaft (14) sharing a common center line with the hollow shaft (8); and a nut (15) threadedly connected to the screw shaft (14). The nut (15) is capable of moving in an axial direction of the screw shaft (14) to enter between the hollow shaft (8) and the screw shaft (14).

A shock assembly with automatically adjustable ride height is disclosed. The assembly includes a main chamber including a fluid therein. A pump tube within the main chamber, the pump tube having a fluid flow path internal thereto, the pump tube disposed axially along a center of the main chamber. A damping piston coupled to a shaft, the damping piston and a portion of the shaft disposed axially about the pump tube, the damping piston disposed in the main chamber to divide the main chamber into a compression side fluid chamber and a rebound side fluid chamber. An automatic ride height adjustment assembly including a tube-in-shaft pump assembly and a spring preload piston assembly.

A vehicle door positioning holder includes a hydraulic cylinder connected to the door and a vehicle chassis, and a brake hydraulically connected in a loop. The cylinder pushes hydraulic fluid in the loop when the door is moved. The brake includes first and second chambers hydraulically connected to the loop and a third chamber connected in the loop at respective ends to the first and second chambers. The brake has a ball element in the third chamber when the hydraulic fluid is still, moved towards the first chamber as the hydraulic fluid flows in a first direction, and moved towards the second chamber as the hydraulic fluid flows in a second direction. A flow resistance of the hydraulic fluid is larger when the ball is positioned in the third chamber than when the ball is moved towards the first or the second chambers.

A trigger device includes an actuation device for converting an electrical activation signal into a movement of an actuator, a control device, which is connected to the actuation device for transmitting an actuation signal and which comprises receiving means for receiving an activation signal, and a power supply unit for supplying the actuation device and the control device with electric power.

A vehicle includes at least one vehicle door or vehicle flap which forms a first body, a vehicle bodyshell which forms a second body, and an impact damper arrangement. The impact damper arrangement is configured such that, when the vehicle door or vehicle flap moves toward the vehicle bodyshell, a first movement section is passed through first, and then a second movement section is passed through. The first movement section is arranged such that movement along the first movement section comes to an end when a lock and closing element come into contact with one another.

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.
