A suspension is provided which can not only generate a damping force between sprung mass and unsprung mass but also steer a wheel. A suspension includes: a shaft coupled to sprung mass of a vehicle, the shaft having a screw groove and a spline groove formed thereon; a ball screw nut assembled to the shaft via a ball; a ball spline nut assembled to the shaft via a ball; a ball screw-specific motor connected to the ball screw nut; a ball spline-specific motor connected to the ball spline nut; and a case coupled to unsprung mass of the vehicle, the case being configured to hold the ball screw-specific motor and the ball spline-specific motor. The ball spline-specific motor rotates the ball spline nut and the shaft relative to the case.

A coupled torsion beam axle (CTBA) bushing is press-fitted into a bushing bracket provided at a tip of a trailing arm at each of two opposite sides of a CTBA suspension system. In particular, the CTBA bushing includes: an outer pipe including a through-hole formed therein; an inner pipe positioned in the through-hole; and a bushing rubber disposed in the through-hole and positioned between an outer peripheral surface of the inner pipe and an inner peripheral surface of the outer pipe, in which the bushing rubber includes: first compounds extending in a first direction, which is a diameter direction of the inner pipe, with the inner pipe interposed therebetween; and a second compounds integrated with the first compounds and extending in a second direction, which is perpendicular to the first direction, with the inner pipe interposed therebetween.

A suspension upright assembly for a vehicle provides a wheel hub bearing and a suspension upright including a fiber-reinforced composite bushing arranged around the wheel hub bearing, attachment members for attaching the suspension upright to a suspension assembly and to a brake caliper of the vehicle, and a fiber-reinforced composite truss-structure that connects at least one of the attachment members to the bushing and/or to a further one of the attachment members.

A stabilizing bar for a vehicle, comprising: a central portion, which is elongate; a first attachment portion configured to be attached to a first part of the vehicle secured to a first wheel of the vehicle; and a first bearing configured to be attached to the chassis of the vehicle, the stabilizing bar comprising, between the central portion and the first attachment portion, a first curved portion, the first curved portion being curved along a curve having a radius of curvature which is strictly increasing with increasing distance from the first bearing.

A vehicle includes a vehicle structure, a wheel assembly, a control arm that is connected to the wheel assembly and the vehicle structure by pivot joints, and an active suspension actuator that is connected to the control arm and to the vehicle structure. The vehicle also includes an air reservoir that includes a first port and an air spring that supports the vehicle structure with respect to the control arm and is able to compress and expand. The air spring includes an internal working volume, the air spring includes a second port that is in fluid communication with the internal working volume, and the second port is connected to the first port to allow exchange of air between the internal working volume of the air spring and the air reservoir in response to compression and expansion of the air spring.

In accordance with one aspect of the present disclosure, a suspension strut for use on a work machine is provided. The suspension strut may have a forged one piece cylindrical inner housing that includes a hollow rod which forms a circumferential piston at an open end and a lower clevis at a closed end of the hollow rod. The suspension strut may further have a forged one piece cylindrical outer housing that includes a hollow barrel having an interior and an exterior surface, a closed end that forms an upper clevis, an open end, and a port on an outside surface of the hollow barrel. Further, the inner and outer housing may be coupled by a disk shaped end cap attached to the open end of the hollow barrel having an inner diameter that is slideably engaged with an outer surface of hollow rod.

A component part for a motor vehicle having a hollow profile portion of a fiber-reinforced plastic and a load introduction element of a metal material. The hollow profile portion and the load introduction element are connected in a common connection portion via a nondetachable, glued plug-in connection in which an end portion of the load introduction element and an end portion of the hollow profile portion engage in one another by positive engagement. The end portion of the load introduction element has a spline with teeth extending in longitudinal direction of the common connection portion so that the stiffness of the end portion of the load introduction element reduced in longitudinal direction of the common connection portion.

An anti-roll bar link for a vehicle suspension may be positioned between an anti-roll bar and an articulating arm. The link selectively transfers movement of the arm to the bar, depending on a locked or unlocked state. The link includes a body interfacing a slidable shaft. A valve selectively controls flow of a damping fluid between an inner chamber of the body and a remote chamber. In the locked state, flow of the damping fluid is restricted at least in a direction from the inner chamber to the remote chamber, and movement of the arm is transferred through the link to the bar. In the unlocked state, flow of the damping fluid is permitted in this direction, and movement of the arm causes the shaft to translate with respect to the body such that at least a portion of the movement is not transferred to the bar.

A hollow stabilizer includes a curved part having eight regions defined in a cross section. A first region includes a 90° first part when the center of the inside of the curve is taken to be at 0° and the center of the outside of the curve is taken to be at 180°. A third region includes a 0° third part. A fifth region includes a 270° fifth part. A seventh region includes a 180° seventh part. The radii of curvature of the respective outer surfaces of the third part and the seventh part are larger and the radii of curvature of the respective outer surfaces of the second part and the sixth part are smaller than the radii of curvature of the respective outer surfaces of the fourth part and the fifth part.

A suspension element includes a housing, a first joint, and a second joint. The housing is configured to couple a tractive element assembly to a vehicle. The housing has a first end configured to engage a portion of the vehicle and a second end configured to interface with the tractive element assembly. The first joint includes a first actuator and a first resilient member. The first actuator is configured to facilitate linear extension and retraction of the suspension element. The second joint includes a second actuator and a second resilient member. The second actuator is configured to facilitate rotational movement of the suspension element. The first resilient member and the second resilient member are configured to support a static load of the vehicle.
