A vehicle height adjusting device which adjusts vehicle height between a vehicle body and a lower arm, may include a suspension spring provided between the vehicle body and the lower arm; a variable portion provided inside an internal diameter of the suspension spring, and whose length is variable by converting a rotary driving motion around an axial direction into an axial rectilinear motion; and a power portion which is provided on the vehicle body, and rotates the variable portion.

A suspension for a vehicle including a strut tube; a strut rod installed so as to be movable in the strut tube; an insulator part through which an upper end of the strut rod is installed, and which includes a lower cup, an insulator body and an upper cup; and a cap member coupled to the upper cup so as to prevent penetration of foreign matters, and having a coupling structure coupled to the upper end of the strut rod. An anti-rotation structure for preventing rotation of the cap member may be provided in the cap member and the upper cup.

This disclosure relates to a suspension thrust bearing device, for use with a suspension spring in an automotive suspension strut of a vehicle. The device comprises a bearing having upper and lower annular bearing members in relative rotation, and a damping element made of resilient material and interposed between the lower annular bearing member and the suspension spring. The damping element comprising at least one deflecting flange for reducing any ingress of water and other pollutants between the upper and lower annular bearing members. The damping element is provided with an annular groove open axially towards the suspension spring, said annular groove radially defining a spring support surface on inner side, and the said deflecting flange on outer side.

The purpose of the present invention is to improve the driving stability of a vehicle in which a double wishbone type or multi-link type suspension is adopted. A double wishbone type suspension has a sliding bearing disposed between a coil spring provided coaxially with a shock absorber and an upper support for mounting the coil spring to the body of the vehicle along with the shock absorber, the sliding bearing permitting the coil spring and the upper support to rotate relative to each other. The sliding bearing permits the coil spring and the upper support to rotate relative to each other with torque lower than torque generated by the torsion of the coil spring caused by the load of the vehicle acting on a damper assembly.

A top mount assembly includes an insulator coupled to a vehicle body; an upper housing coupled to the insulator; a lower housing coupled to the upper housing; a bearing arranged between the upper housing and the lower housing; an inner seal member comprising a seal frame coupled to the upper end portion of the lower housing in a radially inward direction of the bearing, a seal base portion coupled to the seal frame and a plurality of inner seal lips. The seal frame includes a sleeve coupled to the upper end portion of the upper housing and a flange extending from an upper end of the sleeve in a radially outward direction. The seal base portion is coupled to the flange of the seal frame. The upper end of the inner seal lips is disposed to be spaced apart from the inner sidewall of the upper housing.

A suspension structure of a utility vehicle includes: a shock absorber; a knuckle; and an upper arm and a lower arm which connects the knuckle to a vehicle body frame of the utility vehicle, wherein a recessed portion which is recessed downward is formed on the upper arm, and a lower end of the shock absorber is supported by the recessed portion.

A suspension thrust bearing for use with a suspension spring in an automotive suspension strut of a vehicle. The suspension thrust bearing provides a bearing having upper and lower annular bearing members in relative rotation to each other, and having upper and lower bearing surfaces, respectively, disposed in confronting alignment with each other. The lower bearing surface has a contour shaped to axially receive an upper end of the suspension spring. The upper bearing surface is shaped to be axially received by a support block attached to a body of the vehicle. The suspension thrust bearing includes an upper isolator made of resilient material and fixed to the upper bearing surface such that the upper isolator fits between the upper annular bearing member and support block.

A wheel suspension includes an axle limb which supports a wheel. The axle limb includes a first steering axle which provides a first steering angle in a specified range for the wheel, and components for connecting the axle limb to a support structure. At least one of the components includes a second steering axle which provides a second steering angle which is different than the first steering angle provided by the first steering axle. The second steering axle is selectively releasable. The components for connecting the axle limb to the support structure form a double transverse link axle which includes an upper traverse link and a lower traverse link. A support tube is arranged at a chassis-side end portion of each of the upper traverse link and the lower traverse link of the double transverse link axle. The support tube is pivotable about the second steering axle.

A wheel suspension includes an axle limb which supports a wheel. The axle limb includes a first steering axle which provides a first steering angle in a specified range for the wheel, and components for connecting the axle limb to a support structure. At least one of the components includes a second steering axle which is selectively releasable in order to provide a steering angle which is different than the first steering axle. The components for connecting the axle limb to the support structure form a McPherson suspension.

An assembly includes a leadscrew, a strut, and a motor. The strut is movable along the leadscrew upon rotation of the leadscrew. A camber angle of a wheel is changeable according to movement of the strut along the leadscrew. The motor is drivably connected to a rotating shaft that is mounted to the leadscrew.
