A suspension system for a rear axle of a vehicle provided with a frame equipped with at least two side members, the suspension system connecting the axle to said side members and comprising a left side and a right side, each comprising an axle-holder assembly, a bellows, a leaf spring, first and second bars, and a torsion bar interposed between said left and right sides. The aforementioned elements of the suspension system being arranged to provide a functional layout having reduced costs and overall dimensions.

A wheel suspension for a vehicle axle of a two-track vehicle, having a wheel carrier carrying a vehicle wheel, which is able to be articulated to a vehicle body via a multi-link assembly, which multi-link assembly has a trapezoidal link in the form of a four-point link with two connection points on the body side and two connection points on the wheel carrier side. The trapezoidal link connection points on the wheel carrier side are designed with a higher elastic longitudinal compliance, that is, softer, than the trapezoidal link connection points on the body side.

Aspects of the disclosure relate to a mechanical joint with five degrees of freedom. In certain embodiments, the mechanical joint includes first and second triangular linkages The first triangular linkage includes a base end configured to hingedly couple to a first body to pivot relative to the first body and a vertex end that includes a first rotational member. The second triangular linkage includes a base end configured to hingedly couple to a second body to pivot relative to the second body and a vertex end that includes a second rotational member. The first rotational member and the second rotational member are rotationally coupled to form a all joint. With this joint, the second body is moveable in two translational degrees of freedom and restricted in one translational degree of freedom relative to the first body. Such a configuration allows vertical movement and/or reduces stress on the joint.

A swing arm having a reduced number of parts in which manufacturing cost can be reduced. In a swing arm including: vehicle-body-side support portions that are supported on a vehicle body side by a first rotary shaft; wheel-side support portions that are supported on a wheel side by a second rotary shaft; and a pair of arm portions that connect the vehicle-body-side support portions and the wheel-side support portions to each other, cross members that extend in an axial direction of the first rotary shaft is arranged on the pair of arm portions so as to extend between the pair of arm portions, and the cross members have a U shape in cross section orthogonal to a longitudinal direction of the cross members, thus forming opening portions that open so as to face a direction that the pair of arm portions extends.

A suspension system for a wheel of a vehicle including: a wheel interface having a wheel interface axis which is an axis about which a wheel rotates when connected to the wheel interface; a first arm connected to the wheel interface and rotatable with respect to the wheel interface about a first axis that is substantially parallel to the wheel interface axis; and a second arm connected to the wheel interface and rotatable with respect to the wheel interface about a second axis that is substantially parallel to the wheel interface axis; and a damping and springing means disposed within a gap formed between the first arm and the second arm, the damping and springing means are connected at one of its ends to at least one of the first arm, the second arm and the wheel interface; wherein at least a portion of the suspension system is to be disposed within a rim of a wheel.

Rear lower control arm (5) for a motor vehicle including a top part (5t) and a bottom part (5b) defining together a hollow volume (5h), the top and bottom parts (5t, 5b) each including respectively a top and bottom first hole (17t, 17b) and a top and bottom second hole (19t, 19b), wherein the top and bottom parts (5t, 5b) are joined together by securing together at least part of said top and bottom horizontal surface outer peripheries (5tho, 5bho), at least part of the top and bottom first hole side walls outer peripheries (17tso, 17bso), at least part of said top and bottom second hole side walls outer peripheries (19tso, 19bso).

A rear axle assembly designed to fit within a predefined rear axle envelope of a transportation vehicle. The rear axle assembly comprising first and second double wheel hubs each supporting a pair of tires, a rear axle offset with respect to a central axis of the rear axle assembly, a rear axle input for receiving a drive input, first and second portal housings which facilitate respectively connecting the rear axle with the first and the second double wheel hubs, a four-point control arm for connecting the rear axle to a chassis, first and second spring carriers each carrying smaller and larger diameter air bellows, first and second longitudinal arms which interconnected the rear axle to the chassis, and first and second shock absorbers each located generally at or adjacent to the central axis and radially between the first double wheel hub and the first spring carrier.

A vehicle axle with a centrally arranged drive unit and a wheel suspension which has a wheel carrier for holding a wheel, a lower wheel-guiding control arm for the articulated connection of the carrier to a vehicle body, a camber link that connects the carrier to the body and steering unit for steering the wheel. The carrier and control arm are connected directly, in a first connection area, and indirectly via an integral link, in a second connection area, so that the carrier can pivot relative to the control arm about a steering axis. The control arm can be connected to the body in forward and rear areas, and has a rotational axis that extends obliquely relative to the longitudinal direction of the vehicle. All connection areas of the control arm are positioned outside the centrally arranged drive unit relative to the transverse direction of the vehicle.
