The invention relates to an assembly comprising a bushing with a center line L, having an inner sleeve with a mounting bore, an outer sleeve and an elastomeric spring member extending along a height H along the center line L. In one embodiment, the outer surface of the inner sleeve, the spring member and the inner surface of the outer sleeve are on each side of the center line L substantially parallel. On at least one side of the longitudinal center line L, the outer surface of the inner sleeve, the spring member and the inner surface of the outer sleeve extend at an angle to the center line L. An outer surface of the outer sleeve is substantially parallel to the center line L along the height H. Another embodiment of an assembly according to the invention comprises a bushing with a mounting bore that extends at an angle to the center line L. The bushing according to the invention is compact, can be easily manufactured and assembled, take up a high load and can be adjusted to the direction along which forces act on the bushing.

An embodiment suspension structure includes a rail housing configured to be installed in a vehicle body along a height direction of the vehicle body, a rail attached to the rail housing toward an outer side of the vehicle body, a plurality of variable position links configured to be moved in the height direction of the vehicle body by engaging with the rail, a link transfer screw threaded to the plurality of variable position links and disposed in parallel with the rail to allow the plurality of variable position links to move by rotation, and a screw motor fixed to an upper inner side of the rail housing and coupled to one end of the link transfer screw, the screw motor being configured to provide a driving force to rotate the link transfer screw.

A work vehicle includes a chassis. An independent linear suspension system couples to the chassis. The independent linear suspension system includes a driveshaft that couples to the chassis and to a transmission. A wheel hub couples to the driveshaft and rotates a wheel in response to rotation of the driveshaft. A spindle couples to the wheel hub. A spindle carrier couples to the spindle. The spindle carrier defines a first aperture and a second aperture. A first pin extends through the first aperture. A second pin extends through the second aperture. The first pin and the second pin block rotation of the spindle carrier. The spindle carrier moves linearly along the first pin and the second pin.

The invention proposes a method of supplying with hydraulic fluid a hydraulic motor (2) of a drive wheel supporting a vehicle by means of a cylinder-type suspension system (1). The hydraulic fluid passes through a feed duct (25) extending longitudinally through a cylinder (3) of the cylinder-type suspension system (1). The invention also relates to the use thereof in order to eliminate the need for hoses.

An active roll control apparatus is provided. To adjust a stiffness value of the stabilizer bar by moving a stabilizer bar installed between left and right wheels of a vehicle and extending in a first direction and a stabilizer link connected to the stabilizer bar, the active roll control apparatus includes a sliding part having one side connected to the stabilizer bar and the other side connected to the stabilizer link to slide the stabilizer link in a second direction perpendicular to the first direction, and a movement restricting part installed at the sliding part to restrict movement when the sliding part slides.

Systems and methods for controlling wheel motion during a collision are provided. A retaining member may be connectable between a vehicle frame and a wheel assembly to control motion of the wheel assembly during a collision of a vehicle with an object. The retaining member may include one or more of a first attachment point connecting the retaining member to the vehicle frame, a second attachment point connecting the retaining member to the wheel assembly, a retaining member routing, and/or one or more break-away connections attaching the retaining member to the vehicle frame and/or to the wheel assembly. The first and second attachment points, retaining member routing, and/or break-away connections may be selected to control motion of the wheel assembly within a preferred path to control loading between the object and the vehicle.

An actuator for level adjustment of a motor vehicle utilizes a ball screw and a locking unit provided for blocking the ball screw. The actuator has a spindle drive which can be actuated by an electric motor via a gear. The spindle may be fastened to a damper of the chassis of a motor vehicle, to a wheel carrier or to the body or a subframe of a motor vehicle. With the aid of a locking unit of the spindle drive, the rotation of the spindle nut can be optionally blocked or enabled. The locking unit includes a locking element which engages a locking contour attached to the end face of a rotatable element of the gear.

Disclosed is a pulling compensation apparatus for a vehicle including: a main body part capable of loading a power engine of the vehicle and goods or carrying people; a transfer part transferring the main body part; a sensor part sensing a height and a slope of the main body part, pulling due to motion inertia and an obstacle to transmit a signal; a controller embedded with a computer receiving the signal of the sensor part; and a pulling reduction part controlled by the controller to reduce the pulling and shocks of the main body part. The pulling reduction part varies the height to reduce the pulling and shocks of the main body part when the pulling of the main body part and the obstacle are sensed by the sensor part.
