A vehicle has steering and drive wheels supported by legs articulated to the structure of the vehicle. Each leg is rotatably mounted on a main support around a transverse axis. The main support is rotatably mounted about the transverse axis on a base structure, which is connected to the structure of the vehicle. An actuator device is operatively interposed between the main support and the base support to adjust the position of the main support around the transverse axis, and consequently the height of the vehicle from the ground. A hub-bearing support carrying the wheel hub is rotatably mounted around a wheel steering axis on an auxiliary camber adjustment support. The latter is carried around a camber adjustment axis on a further auxiliary caster adjustment support. The latter is carried by the leg around a caster adjustment axis. The steering of the wheel and the camber adjustment are controlled by respective actuator devices. The caster adjustment is automatically controlled as the position of the leg changes around the transverse axis.

A motor vehicle rear axle is of the type having two longitudinal trailing arms. Each trailing arm has a stub-axle bracket at one rear end and, at an opposite front end, a substantially transverse axis of rotation defined by a first joint and a second joint which are intended to be connected to the vehicle body. A first and a second support element are located respectively in front of and behind a trailing arm on the side of its second joint. The free ends of these support elements, located in the longitudinal and vertical median plane of the rear axle, are kept at a longitudinally fixed distance by a connecting element.

A universal wishbone trailing arm and methods are provided for coupling a wheel to a vehicle chassis. The universal wishbone trailing arm comprises a wheel hub that fastenably receives the wheel. A cylindrical axle support supports one or more roller bearings whereby the wheel hub is rotatable. A first swing arm and a second swing arm extend forwardly from a joined swing arm. The cylindrical axle support is coupled to a rear of the joined swing arm. A first chassis mount hingedly couples the first swing arm to the vehicle chassis. A second chassis mount hingedly couples the second swing arm to an articulated mount which is configured to couple the second swing arm to the vehicle chassis. The articulated mount cooperates with the first second swing arms to change the camber of the wheel, such that a tracking of the wheels remains substantially unchanged during traveling over rough terrain.

A method and apparatus for installing a wheel arm assembly for an autonomous vehicle. The wheel arm assembly may be inserted into a base of the autonomous vehicle from the exterior of the base. A number of fasteners may be installed at the exterior of the base to attach the wheel arm assembly to the base of the autonomous vehicle.

Provided is a vehicle which, when a pair of left and right wheels are displaced with respect to the vehicle body due to the difference in drive force between the wheels, the two wheels are reliably displaced vertically in opposite directions such that neither wheel is disproportionately displaced and such that both wheels are steered during said displacement of both wheels vertically in opposite directions. The pair of left and right front wheels (3) are rotatably supported by a front wheel support member (29). An electric motor (25) applies drive torque to the front wheels (3) individually. A vehicle body frame (7) supports the front wheel support member (29) to allow rotation about a forwardly inclined steering axis (Lf). By allowing rotation of the front wheel support member (29) about the steering axis (Lf), the front wheels (3) are displaced relatively to one another vertically in opposite directions with respect to the vehicle body frame (7) and the front wheels (3) are steered. The front wheel support members (29) rotate due to the difference in torque applied to the front wheels (3) by the electric motor (25).

A wheel suspension device for a vehicle includes a beam connectable to a frame of the vehicle and a wheel spindle for receiving a wheel, wherein the wheel spindle has an axis coinciding with the intended wheel rotation axis, and the beam has a pivot axis for pivoting the beam relative to the frame about the pivot axis. The wheel spindle is arranged on the beam for enabling the wheel to move up and down relative to the frame by pivot motion of the beam and the beam pivot axis and the wheel spindle axis are angled relative to each other.

A wheel suspension for a vehicle with a supporting vehicle element includes at least one pair of single-sided swing arms. Each single-sided swing arm is associated with a hydraulic cylinder, which is linked to the single-sided swing arm and/or the supporting vehicle element. Each hydraulic cylinder is subdivided in a fluid-tight manner into two chambers.

A suspension assembly of an axle/suspension system for a heavy-duty vehicle is mounted on the heavy-duty vehicle frame or sub-frame via a beam of the suspension assembly which is pivotally connected to a hanger connected to the vehicle frame. The pivotal connection includes the hanger, the beam, a bushing assembly and a fastener group, and a textured feature formed in at least one of at least a portion of the hanger, at least a portion of the bushing assembly, or at least a portion of the fastening means so that the textured feature inhibits relative movement of the bushing assembly with respect to the hanger.

An off-road vehicle includes a frame, a front suspension, and a rear suspension. In some examples of the off-road vehicle, the rear suspension includes trailing arms with are pivotally attached to the frame rearward of an operator area. Further, the frame can include a front subframe assembly and a rear subframe assembly which are easily removable from the main frame of the vehicle to permit access to various components of the off-road vehicle.

Provided is a vehicle which, when a pair of left and right wheels are displaced with respect to the vehicle body due to the difference in drive force between the wheels, the two wheels are reliably displaced vertically in opposite directions such that neither wheel is disproportionately displaced and such that both wheels are steered during said displacement of both wheels vertically in opposite directions. An electric motor applies drive torque to the front wheels individually. A vehicle body frame supports the front wheel support member to allow rotation about a forwardly inclined steering axis (Lf). By allowing rotation of the front wheel support member about the steering axis (Lf), the front wheels are displaced relatively to one another vertically in opposite directions with respect to the vehicle body frame and the front wheels are steered.
