A recreational off-highway vehicle includes a vehicle frame, least one front wheel, a pair of rear wheels, a pair of rear suspensions, a rear differential and a motor. The rear suspensions connect the rear wheels to the vehicle frame. The rear differential connects to the rear wheels. The motor is connected to the rear differential to drive the rear wheels. Each rear suspensions includes a trailing arm, a floating rear knuckle, a shock absorber and a plurality of control links. The trailing arm has a front end pivotally connected to the vehicle frame. The floating rear knuckle is pivotally connected to a rear end of the trailing arm. The shock absorber is coupled between the vehicle frame and the trailing arm. The control links have first ends movably supporting the floating rear knuckle and second ends pivotally connected to the vehicle frame forward of the rear differential.

A utility vehicle includes a rear suspension assembly which has a trailing arm generally extending longitudinally. 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.

An aerodynamic cover of a suspension device of a vehicle includes an upper horizontal portion that is located on an upper side of the arm member and extends in a horizontal direction, a lower horizontal portion that is located under the arm member and extends in the horizontal direction, an engaging portion that is provided on one of the upper and lower horizontal portions and engaged with the arm member, and a bolt receiving portion that is provided on the other horizontal portion and bolted to the arm member. The engaging portion includes an arm portion extending in the horizontal direction, and a claw portion provided on a distal side of the arm portion and engaged with the arm member. A rib provided on the arm portion extends in a direction of extension of the arm portion, and protrudes in a vertical direction with respect to the arm portion.

A vehicle has a frame, seats, front and rear suspension assemblies, front and rear wheels, a motor, a rear differential, left and right constant velocity joints operatively connected to the rear differential; and left and right half-shaft operatively connecting the constant velocity joints to the rear wheels. Each of the rear suspension assemblies has: a trailing arm having a front end pivotally connected to the frame; a knuckle pivotally connected to a rear portion of the trailing arm; lower and upper links pivotally connected between the trailing arm and the frame; and a toe link pivotally connected between the knuckle and the frame. Each of the rear suspension assemblies has an instant center axis passing through a connection between the trailing arm and the frame. Centers of the velocity joints are laterally outward of their corresponding instant center axes when viewed in a top plan view of the vehicle.

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.

An outdoor power equipment unit includes a front wheel independent suspension system. The front wheel independent suspension system includes a frame, a first front wheel assembly, a second front wheel assembly, a first laterally-extending suspension arm pair, and a second laterally-extending suspension arm pair. The first laterally-extending suspension arm pair includes a first suspension arm and a second suspension arm, both coupled to the frame and the first front wheel assembly. The second laterally-extending suspension arm pair includes a third suspension arm and a fourth suspension arm, both coupled to the frame and the second front wheel assembly. Both the first suspension arm pair and the second suspension arm pair are configured to independently pivot about the frame such that each of the first front wheel assembly and the second front wheel assembly are vertically displaceable relative to the frame.

An outdoor power equipment unit includes independent suspension system having a frame, a first wheel assembly, a second wheel assembly, a first laterally-extending suspension arm pair, and a second laterally-extending suspension arm pair. The first wheel assembly includes a first wheel and a first side suspension arm. The first side suspension arm is pivotably coupled at a first end to a first side structural member and is fixedly coupled at a second opposite end to a joint of the first wheel assembly. The second wheel assembly is arranged similarly to the first wheel assembly. Both the first laterally-extending suspension arm pair and the second laterally-extending suspension arm pair are configured to independently pivot about the frame to be vertically displaceable relative to the frame.

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.
