A strut assembly including a first cylinder, a second cylinder configured to reciprocally move within the first cylinder, and a damper assembly positioned within the first cylinder. The damper assembly includes a housing having opposing first and second ends, a floating piston in the housing and a damper piston positioned between the floating piston and the first end of the housing. The damper piston divides the housing into first and second chambers, where the first and second chambers include a hydraulic fluid that provides resistance to the movement of the damper piston in the housing. The strut assembly also includes a gas spring in the first and second cylinders, where the gas spring includes a pressurized gas contained within the first and second cylinders.

A linking device links an aluminum side rail of a vehicle body structure and an end of a control arm that includes a cylindrical linking ring. The device remarkably includes an aluminum casting including an upper surface attached under the side rail, and a side wall from which emerges, perpendicular to an outer side surface, at least one first control arm interface including a pair of tabs separated from one another by an air-gap value greater than the length of the cylindrical ring, in order to set the end of the control arm.

A front body structure of the vehicle has a pair of left and right suspension housings provided in desired positions separated from the dash panel toward the vehicle front side. The front body structure of the vehicle further includes a first ring-shaped structural frame that passes through shroud members and is substantially ring-shaped in front view, a second ring-shaped structural frame that passes through the suspension housings and is substantially ring-shaped in front view, and a third ring-shaped structural frame that passes through hinge pillars and is substantially ring-shaped in front view, in which these ring-shaped structural frames are joined to each other by apron reinforcements, front side frames, and side members of the sub-frame.

A front body structure of a vehicle includes a pair of left and right hinge pillars, a pair of left and right front suspension dampers that are provided in desired positions on an inner side in a vehicle width direction of the hinge pillars and on a vehicle front side of the hinge pillars, a pair of left and right suspension housings that have damper mount parts, and a pair of left and right apron reinforcements to which upper ends of the suspension housings are joined. The apron reinforcements are formed in shapes extending substantially linearly from the rear ends thereof toward the vehicle front side and an inner side in the vehicle width direction through an outer side in the vehicle width direction of the damper mount parts in plan view.

A rear subframe structure is provided with a rear subframe configured such that a front cross member, a rear cross member, a pair of left and right upper side members, and a pair of left and right lower side members are connected; and a vehicle-body mounting portion formed. The rear subframe further includes a lower-arm support portion. The front cross member has a closed section, and a front portion of the closed section extends downwardly by forward and downward inclination of a left lateral portion and a right lateral portion of the front cross member. The lower-arm support portion is formed on a lower rear portion of the left lateral portion and the right lateral portion of the front cross member. The upper side member is connected to an upper rear portion of the left lateral portion and the right lateral portion of the front cross member.

In a suspension member having a closed cross section, insertion holes are respectively formed in an upper member and a lower member that are two opposing walls. A collar includes a cylindrical portion and a flange. The cylindrical portion is inserted through the insertion holes. On the upper member side, the cylindrical portion and the upper member are welded together, forming a weld bead. On the lower member side, the outer circumferential edge of the flange and the lower member are welded, forming a weld bead. The welding is applied so that the length of the welding line on the lower member side is longer.

In an embodiment, the present invention provides a stop device for limiting a vertical spring deflection of a motor vehicle leaf spring that is mounted on an axle member, the stop device including: a stop which limits a vertical movement of the leaf spring; a support structure for supporting and mounting the stop on a vehicle support; and a guiding device for receiving and guiding at least one of a cable, a line, and/or a holder. The guiding device is fastened to the support structure.

A shock tower assembly includes a shock tower body comprised of a polymer composite material, at least one reinforcement member integrated into the shock tower body, and a wheel cover comprised of the polymer composite material and integrated into the shock tower body to form a single-piece component.

The present invention provides embodiments of modified upper and lower control arms for attachment to the steering knuckle that came with the vehicle, or for attachment to a modified steering knuckle of an embodiment of the invention, such that the steering knuckle, and in particular the wheel hub opening of the steering knuckle, are located at positions that are closer to the front of the vehicle than the positions provided by the control arms that came with the vehicle. The forward position of the wheel hub relative to the position provided by the factory or stock control arms moves the wheel and tire forward by the same distance, thereby allowing much larger wheels and tires to be mounted on the vehicle which do not rub against or interfere with the wheel well, fender or body mount, thereby increasing the approach angle of the vehicle for use in off-road climbing.

A leaf spring apparatus for a vehicle suspension includes a leaf spring, a carrier disposed on an end portion of the leaf spring and mounted on a wheel of a vehicle, a first connection unit connecting the end portion of the leaf spring and the carrier to each other, a cross member disposed on top of the leaf spring and supporting a body of the vehicle, and a second connection unit connecting the leaf spring and the cross member to each other.
