A vehicle includes an assembly for providing suspension and steering for a wheel. The assembly includes an inner knuckle and a steering knuckle. The inner knuckle is coupled to an upper control arm at an upper joint and a lower control arm at a lower joint, forming a double wishbone suspension. The upper joint and the lower joint define a first axis. The steering knuckle is coupled to the inner knuckle at a steering joint that forms or otherwise defines a kingpin axis. The steering joint includes a revolute joint, a ball joint, or both. The steering knuckle is configured to be engaged with a tie-rod coupled to a steering mechanism. The kingpin axis is nearer a center of the wheel than the first axis, thus preventing or otherwise limiting torque steer. The upper and lower joints are constrained from significant steering rotation by suitable bushings, anti-steer arms, or both.

A void bushing for a vehicle suspension is configured to have protrusion parts formed to protrude outwards on a bulge part of an inner pipe. The protrusion parts are located to be disposed in oblique line directions between void portions of an elastic body that is filled between the inner pipe and an outer pipe. In the void bushing, ride comfort characteristics and durability characteristics of a vehicle may be maintained, as they are, under favorable conditions by the void portions. Further the handling response characteristics of the vehicle may be advantageously improved by promoting a rigidity increase through the protrusion parts.

A suspension includes a housing, links, a radius arm, and a radius arm bush. The radius arm bush is provided on a front end of the radius arm, couples the radius arm to a vehicle body, with an elastic body in between, and is disposed vehicle-widthwise inwardly of a wheel center contact point of the rear wheel. The radius arm bush has higher rigidity with respect to turn of the radius arm with respect to the vehicle body in a direction in which an underside of the radius arm is displaced vehicle-widthwise outwardly from an upside of the radius arm, than rigidity with respect to turn of the radius arm with respect to the vehicle body in a direction in which the underside of the radius arm is displaced vehicle-widthwise inwardly from the upside of the radius arm.

A bushing for a wheel suspension adapted to connect a control bar to a structure of a vehicle, where the bushing comprises a first rotational center for the control bar having a first angular rotation range, where the bushing comprises a second rotational center for rotational angles outside of the first angular rotation range.

A bushing for use in an axle/suspension system of a heavy-duty vehicle. A beam supports an axle for pivotal movement with a hanger of the heavy-duty vehicle at a pivot connection. A bumper is fixed to the beam and contacts an engagement member of the heavy-duty vehicle to limit the relative pivotal movement of the beam and axle in one direction. A force is applied to the pivot connection in a force application direction that is angularly spaced from horizontal and vertical planes. The pivot connection includes a bushing to connect the beam and the hanger. The bushing includes an elastomeric bushing body with at least one void for decreasing rigidity of the bushing body in a substantially vertical direction. The one void is located in the bushing body angularly spaced from the force application direction. The bushing body is substantially solid along the force application direction.

A chassis arrangement and method for leveling a vehicle with at least one vibration damper permitting an active height adjustment. The chassis arrangement has a stabilizer having a restoring force that rises with a first slope during a transverse acceleration in a first range up to a first threshold value and has a restoring force which rises with a second slope after the first threshold value in a second range. The second slope is greater than the first slope.
