A suspension assembly for a commercial vehicle includes a first linkage, an air spring, a carriage, and a second linkage. The first linkage is pivotally coupled at a first end with a structural member of a frame. The structural member extends downwards from the frame. The air spring is coupled with the frame and a second end of the first linkage. The air spring drives the first linkage to pivot about the first end relative to the structural member. The carriage is pivotally coupled with the first linkage at a position between the first end and the second end of the first linkage. The second linkage is pivotally coupled at a first end with the structural member, and pivotally coupled with the carriage at a second end. The structural member, the first linkage, the second linkage, and the carriage define a four-bar linkage.

An all-terrain vehicle is provided. The vehicle includes a lateral stabilizer bar and a shock absorber. The lateral stabilizer bar further includes a main bar, two side bars and ball-pin connecting rods. The side bars are connected to two sides of the main bar respectively and bent backward relative to the main bar, ends of the side bars are disposed on a suspension assembly, the main bar is disposed at the front end of a frame and located in front of a radiator, the ends of the two side bars are connected to the ball-pin connecting rods respectively, and the ball-pin connecting rods are disposed on the upper rocker arm. The side bars and the ball-pin connecting rods of the lateral stabilizer bar are located on an inner side of the shock absorber.

A method and apparatus for adapting a vehicle rear suspension wherein the apparatus comprises a substantially circular plate having first and second surfaces with a central bore therethrough and with closed and open notches extending into a circumferential edge thereof, a pair of outer mounting bores extending through the plate proximate to the circumferential edge with the closed notch therebetween and a plurality of first and second inner mounting bores distributed around the central bore. The method comprises removing a multi-link rear suspension assembly from the vehicle and removing left and right wheel assemblies from the multi-link rear suspension assembly mounting an adaptor plate to each of the left and right wheel assemblies on an inside surface thereof with a first set of fasteners, mounting an axle beam of a torsion bar rear suspension assembly to each of the adaptor plates with a second set of fasteners and securing the torsion bar rear suspension assembly to the vehicle.

An installation structure of an in-wheel motor unit including a motor, a speed reducer, and a housing, for installing the in-wheel motor unit on a carrier of a suspension apparatus such that the housing is sandwiched by and between the carrier and a bearing unit, wherein the bearing unit and the housing are fastened at first fastening positions, and the carrier and the housing are fastened at second fastening positions the number of which is the same as that of the first fastening positions, wherein each first fastening position and the corresponding second fastening position form a pair, so as to provide a plurality of fastening-position pairs, and wherein the first and second fastening positions of each pair are located at the same position or located close to each other when viewed in a wheel axis direction which is a direction in which a rotation axis of a wheel extends.

The vehicle suspension component includes first and second trailing arms that are spaced from one another for attachment with vehicle wheels. The suspension component also includes at least one cross-member that is rigidly connected with the first trailing arm and is operably connected with the second trailing arm in a non-rigid manner. A rotation inhibitor operably connects the at least one cross-member with the second trailing arm and resiliently resists rotation of the at least one cross-member relative to the second trailing arm.

A vehicle includes a rear wheel suspension including a twist beam axle. The vehicle also includes upper and lower mounts for a spring and each defining a seat. The lower mount is disposed on the axle and the upper mount is disposed at a distance and parallel to the lower mount on a frame member. A first adapter is disposed within the lower mount seat and a second adapter is disposed within the upper mount seat. Each adapter defines a groove to receive an end of the spring, a support extending from the groove within an inner diameter of the spring and a wall disposed along a segment of the groove being configured to maintain a position of the spring.

A suspension device (rear suspension (10)) for vehicles is provided which includes a damper (40), a shaft (50) pivotably supporting an end of the damper (40), and a bush (60) including a cylindrical elastic member fitted onto the outer circumference of the shaft (50). The axis (C2) of the bush (60) is disposed along a line of intersection between an imaginary first plane (S1) and an imaginary second plane (S2), or along a line parallel to the line of intersection. The first plane (S1) is orthogonal to the axis (C1) of the damper (40) when a stroke position of a wheel (24) is a first position relative to the vehicle body (80) in the vertical direction of a vehicle body (80). The second plane (S2) is orthogonal to the axis (C1) of the damper (40) when the stroke position of the wheel (24) is a second position.

An axle for a vehicle, wherein the axle includes a transverse axle portion having a longitudinal end. The axle including a first axle portion connecting the transverse portion to a chassis of the vehicle and a second axle portion connecting the transverse portion to a wheel carrier for supporting a vehicle wheel. A vibration damper is arranged in a receiver in one of the axle portions.

An axle assembly includes a first rail assembly, a second rail assembly and an open-section twist beam connected to the first rail assembly and the second rail assembly. The twist beam includes an upper wall, a lower wall and rear wall wherein the upper wall and the lower wall are connected by the rear wall to define an open portion of the twist beam where the upper wall and the lower wall are separated by a vertical distance. The open portion of the twist beam is forward facing. The axle assembly further includes a torsion bar that extends through and is connected within the open portion of the twist beam.

A system for opening and closing a closure of a vehicle, such as a door or a tailgate, is provided. The system includes a motor such as an electric motor which may be coupled to the closure via an output linkage, with the output linkage mechanically coupled to the closure and operable to move the closure between a closed position and an open position. The output linkage may include a driven pulley which may be coupled to the motor. The output linkage may include a driven pulley and a cable. The output linkage may include a leadscrew threadedly engaging a nut. A high-bandwidth MR clutch having a high dynamic response may selectively couple the motor with the closure to provide a haptic or tactile feedback to a user interacting with the closure as it is opened or closed.
