A utility vehicle includes a rear suspension assembly which has a trailing arm generally extending longitudinally. The trailing arm includes a joint along a longitudinal length of the trailing arm. Also, the rear suspension assembly includes an upper radius rod extending in a generally lateral direction relative to a centerline of the vehicle. Additionally, the rear suspension assembly includes a lower radius rod extending in a generally lateral direction relative to the centerline of the vehicle. The rear suspension assembly further includes a suspension member configured to control toe of the at least one rear ground-engaging member.

A suspension structure of a utility vehicle includes a frame, a wheel, and a trailing arm including an arm extending anteroposteriorly and supported by the frame, a knuckle rotatably supporting the wheel, and a rotary shaft configured to angularly displace the knuckle in a vehicle width direction with respect to the arm.

An apparatus for coupling a trailing arm may include a carrier having defining an open space on one side thereof, a trailing arm, one end of which includes an extension inclined at a predetermined angle and inserted into the space, and an assist arm, an end of which is inserted into the space and positioned on one side of the extension, in which the extension and the end of the assist arm inserted into the space may be integrally coupled to the carrier.

A spring device for a motor vehicle wheel suspension that includes a first leaf spring made of fiber-reinforced plastic and a second leaf spring made of fiber-reinforced plastic. The second leaf spring is shorter than the first leaf spring and together with the first leaf spring forms a V-shaped structure, which, in the region of the joined ends of the V-shape, has a first fastening device for the vehicle-body-side support and at the free ends of the V shape has a second fastening device on the first leaf spring for wheel-side support and a third fastening device on the second leaf spring for vehicle-body-side support.

A vehicle may include a CVT unit or a power source which requires ambient air. An air inlet for an air intake system coupled to the CVT unit or the power source which requires ambient air may be provided in a side of a cargo carrying portion of the vehicle. The vehicle may include a rear radius arm suspension.

The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces.

A motor vehicle multi-link axle having wheel suspension including a lower transverse link and an upper transverse link. A leaf spring extending transversely to a direction of travel of the vehicle and below the upper transverse link. A link element connects an end of the leaf spring to the upper transverse link. The link element having a first connection, connected to the upper transverse link, and a second connection, connected to the leaf spring. The link element adjustable to vary the distance between the first connection and the second connection. The multi-link axle may also include a connecting element that connects the second connection point of the link element to a connection point of the leaf spring, with the connecting adjustable to vary the distance between the second connection point of the link element and the connection point of the connecting element to the leaf spring.

A frame for an off road vehicle includes main beams establishing a base plane. Mounting beams, which can be used to support forces from the swing arm of a rear suspension, are spaced outside the main beams and within the base plane, running longitudinally in line with the swing arms of the rear suspension. Right and left longitudinal beams start within the base plane, but rise to their trailing ends so as to not interfere with the suspension travel of the swing arms as they extend back inward over the swing arms. Front and rear support columns can further attach into, secure and support the mounting beams and the longitudinal beams. All of the beams and columns can be formed by cutting cylindrical tubing to length and then curving the cylindrical tubing, each piece within a single plane.

The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces.
