A suspension is provided for coupling a front wheel with a chassis of an off-road vehicle. The suspension comprises upper and lower suspension arms that each includes two inboard mounting points to the chassis and one outboard rod-end joint to a spindle assembly coupled with the front wheel. A ball comprising each outboard rod-end joint is fastened by way a bolt between a pair of parallel prongs extending from the spindle assembly. The upper suspension arm is configured to facilitate coupling a strut between the lower suspension arm and the chassis. A steering rod is coupled with the spindle assembly by way of a steering rod-end joint that is disposed forward of a drive axle, thereby decreasing leverage of the front wheel on the steering rod and substantially eliminating bump steer that may occur due to rough terrain.

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.

A suspension structure of a utility vehicle includes: a shock absorber; and a trailing arm extending in a longitudinal direction of the utility vehicle. A lower end of the shock absorber is supported by a rear end of the trailing arm within a wheel as viewed in a side view of the utility vehicle.

Provided is a trailing arm riding mower suspension system that includes trailing arms adapted to support hydraulic motor units and having leading ends pivotally coupled to a mower frame by way of leading end spherical joints and trailing ends having hydraulic drive unit mounts, where the trailing arms are adapted to pivot about leading end pivot locations defined by the leading end spherical joints.

A vehicle wheel assembly includes a wheel, a tire supported by the wheel, an internal space defined by the wheel, a wheel hub that is rotatably connected to the wheel and is located in the internal space, and a mass actuator that is connected to the wheel hub and located in the internal space.

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 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 rod-end front suspension is provided for an off-road vehicle. The rod-end front suspension comprises a spindle assembly that is pivotally coupled with an upper suspension arm by way of a first rod-end joint and pivotally coupled with a lower suspension arm by way of a second rod-end joint. A steering rod-end joint coupled with the spindle assembly pivotally receives a steering rod. An axle assembly coupled with the spindle assembly conducts torque from a transaxle to a wheel coupled with the spindle assembly. Each of the first and second rod-end joints comprises a ball rotatably retained within a casing. The ball is fastened within a recess between parallel prongs extending from the spindle assembly. A threaded shank extending from the casing is threadably fixated with the suspension arm, such that the spindle assembly may be moved with respect to the casing and the suspension arm.

The present disclosure relates to a suspension system for an all-terrain vehicle. The suspension system includes a mount for a rear wheel shaft having a front portion and a rear portion; a toe controlling rod having an outer end coupled to the front portion and an inner end opposite the outer end; and a brake coupled to the rear portion. The present disclosure also relates to another suspension system for an all-terrain vehicle and an all-terrain vehicle.
