A vehicle height adjustment system includes: an input housing part having a space in which working fluid is stored; an input piston part positioned in the input housing part, the input piston part configured to move along a lengthwise direction of the input housing part; a lead screw inserted into the input piston part, the lead screw configured to move in response to receiving external power; and a connection part fastening the input piston part with the lead screw.

A damper includes a damper tube (a pressure tube or a reserve tube for a mono-tube or a double tube damper respectively) including a first end and a second end opposite to the first end. The damper includes a base member. The base member includes a cup portion at least partially enclosing the first end of the damper tube, and a sleeve portion extending from and integral with the cup portion. The sleeve portion surrounds a length of the damper tube. The sleeve portion is attached to the damper tube. Further, the damper includes a knuckle engaged with the sleeve portion such that the sleeve portion is disposed between the knuckle and the damper tube.

The invention relates to a connection system for connecting a damper unit of a vehicle inside a wheel suspension of the vehicle, the connection system having: an upper attachment region for attaching the damping unit, at least part of said region surrounding a receiving area for the damping unit and the receiving area extending around a first axis acting as the damping axis of the damping unit; a lower attachment region for coupling to the wheel-side portion of the wheel suspension, said lower attachment region having, in particular, two mutually spaced lower sections with an attachment area therebetween and an intermediate region which connects the upper attachment region to the lower attachment region. The main extension of the intermediate region corresponds to the direction of the first axis and the intermediate region allows the passage of a drive shaft of the vehicle. The connection system is made of an extruded part, the extrusion direction of which is the direction in which the extruded material extends, said material thus forming the intermediate region of the connection system. The invention also relates to a connection system comprising a clamping mechanism.

An offset washer for adjusting the camber angle in a vehicle is disclosed. The offset washer includes a body having an upper surface and a lower surface, an aperture extending through the body, and a protrusion having a longitudinal width different than the body thickness. The protrusion is configured to be inserted into a receiving aperture on a flange of a vehicle suspension system. The protrusion is defined by a formed upset defining a step in the material along a portion of the edge of the aperture, which is formed by upsetting the portion of the edge of the aperture when forming the aperture.

A suspension apparatus may include an internal cylinder having fixing grooves, an intermediate cylinder rotatably provided around the internal cylinder to allow a shock-absorber to be moved up and down, and having connection holes, an external cylinder rotatably provided around the intermediate cylinder and having locking pins to be inserted into the fixing grooves through the connection holes such that the locking pins are decoupled from the fixing grooves, but remain inserted into the connection holes, and a driving device connected to the external cylinder to rotate the intermediate cylinder to allow the shock-absorber to be moved up and down, adjusting a height of a vehicle body.

A vehicle suspension apparatus configured for adjusting vehicle height may include a fixing device disposed at a wheel side, provided on an internal peripheral surface along its perimeter with a plurality of fixing grooves; a moving device provided to be rotatable within the fixing device, formed along its perimeter with coupling grooves corresponding to the fixing grooves and coupled such that a shock absorber moves in an up and down direction; a driving device disposed at the fixing device to transmit power; and a drive shaft provided to be rotatable within the moving device and provided with a fixing pin inserted into the coupling groove of the moving device and the fixing groove of the fixing device such that the fixing pin is disengaged from the fixing groove and remains inserted only into the coupling groove when the drive shaft rotates.

The invention relates to a strut rod made of composite material for a suspension of a front axle of a vehicle, including: an upper part coupled to a rod and piston assembly connected to a vehicle body; and a U-shaped lower part including two brackets for fixing a knuckle arm of the vehicle. This strut rod includes means for detecting a crack. This detection means includes at least one additional edge positioned so as to project from an outer surface of the U-shaped lower part of the strut rod in a region where a crack possibly occurs in the case of an accidental shock on a wheel of the vehicle.

A damper spring support includes: a first angle adjustment mechanism configured for being fixed to a vehicle body; a support base configured for supporting a damper spring; and a connection structure configured for detachably fixing the support base to different positions of the first angle adjustment mechanism. If the support base being fixed to different positions of the first angle adjustment mechanism, a damper spring support surface of the support base facing different directions. A vehicle axle having the same is also included.

A vehicle suspension apparatus configured for adjusting vehicle height may include a fixing device disposed at a wheel side, provided on an internal peripheral surface along its perimeter with a plurality of fixing grooves; a moving device provided to be rotatable within the fixing device, formed along its perimeter with coupling grooves corresponding to the fixing grooves and coupled such that a shock absorber moves in an up and down direction; a driving device disposed at the fixing device to transmit power; and a drive shaft provided to be rotatable within the moving device and provided with a fixing pin inserted into the coupling groove of the moving device and the fixing groove of the fixing device such that the fixing pin is disengaged from the fixing groove and remains inserted only into the coupling groove when the drive shaft rotates.

A suspension apparatus may include an internal cylinder having fixing grooves, an intermediate cylinder rotatably provided around the internal cylinder to allow a shock-absorber to be moved up and down, and having connection holes, an external cylinder rotatably provided around the intermediate cylinder and having locking pins to be inserted into the fixing grooves through the connection holes such that the locking pins are decoupled from the fixing grooves, but remain inserted into the connection holes, and a driving device connected to the external cylinder to rotate the intermediate cylinder to allow the shock-absorber to be moved up and down, adjusting a height of a vehicle body.
