A front independent suspension assembly for outdoor power equipment includes a first joint, a first wheel coupled to the joint, a first longitudinal arm pivotably coupled to the joint, a first lateral arm pivotably coupled to the joint, and a second lateral arm pivotably coupled to the joint. The second lateral suspension arranged substantially parallel to the first lateral suspension arm. The pivotal coupling between the joint and each of the first longitudinal arm, the first lateral arm, and the second lateral arm enables the first wheel to independently displace about a vertical axis

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 modular chassis is provided for an off-road vehicle to improve assembly, servicing, and repairing of a drivetrain of the off-road vehicle. The modular chassis includes a chassis to support components of the off-road vehicle. A front frame module couples with a front of the chassis, and a rear frame module couples with a rear of the chassis. The front frame module supports lower suspension arms of the off-road vehicle by way of inboard bushing joints. The front frame module supports at least a steering gear and a front differential of the off-road vehicle. The rear frame module is a tube-frame structure that supports components of the off-road vehicle. A lower portion of the rear frame module extends rearward and acutely upward to a top frame member that couples with upper side portions of the chassis. Several cross-members impart structural integrity to the rear frame module.

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.

A universal axle-hub assembly is provided for an off-road vehicle. The universal axle-hub assembly comprises a wheel hub that receives a constant velocity (CV) axle snout into an opening extending through an axle support of the wheel hub. An outboard-most portion of the opening is a splined portion that engages with similar splines disposed on an outboard-most portion of the CV axle snout. An inboard-most portion of the opening is a smooth portion that receives a smooth portion of the CV axle snout. The axle support extends through an entirety of the width of a bearing that supports the wheel hub, such that the bearing supports the smooth portion of the CV axle snout and substantially eliminates shear forces acting on the splined portion of the CV axle snout. A bearing carrier supports the bearing and may be fastened onto a trailing arm or a spindle of the off-road vehicle.

A motor vehicle independent rear-wheel suspension system including a left-hand and a right-hand transverse link, each articulated at an inner end on a chassis of the motor vehicle and fixedly connected at an outer end to a wheel carrier. The suspension system having a left-hand and a right-hand trailing arm unit. Each trailing arm unit articulated a front end on the chassis of the motor vehicle and at a rear end on a wheel carrier. Open installation space is formed between the trailing arm units and the transverse links for at least a partial accommodation of an electrical drive train.

A low suspension arm strut coupling is provided for a suspension of an off-road vehicle. The suspension comprises a lower suspension arm that is hingedly coupled between a chassis of the off-road vehicle and a spindle assembly that is coupled with a front wheel. An upper suspension arm is hingedly coupled between the chassis and the spindle assembly. A strut is coupled between the lower suspension arm and the chassis. A lower pivot couples the strut to the lower suspension, and an upper pivot couples the strut to the chassis. The upper and lower pivots provide a lower center of gravity of the off-road vehicle and a relatively smaller shock angle. The lower suspension arm is reinforced to withstand forces due to movement of the front wheel and operation of the strut in response to travel over terrain.

Provided is a supporting structure for a shock absorber of a suspension device of a utility vehicle. The supporting structure for a shock absorber includes a shock absorber and a vehicle body frame. The shock absorber is supported on a support portion of the vehicle body frame from below the vehicle body frame, and a rollover protective structure (ROPS) is connected to the support portion from above the vehicle body frame.

A vehicle that can reduce change in the toe angle of a rear wheel in a toe-out direction at the time of a braking force being provided by the vehicle. A coupling point between a vehicle frame and a trailing arm is defined as a first coupling point. A coupling point between the trailing arm and a lateral arm is defined as a second coupling point. A coupling point between the lateral arm and a frame rear section is defined as a third coupling point. A straight line connecting the first coupling point and the second coupling point is defined as a first straight line. A straight line connecting the second coupling point and the third coupling point is defined as a second straight line. With those definitions, an angle between the first straight line and the second straight line in a plan view of the vehicle is 90 degrees or greater.

A leading-edge steering system is provided for a front suspension of an off-road vehicle. The leading-edge steering system is comprised of a spindle assembly that supports a drive axle assembly to conduct torque from a transaxle to a front wheel. A first rod-end joint pivotally couples an upper suspension arm and the spindle assembly, and a second rod-end joint pivotally couples a lower suspension arm and the spindle assembly. A steering rod-end joint pivotally couples a first end of a steering rod with a leading-edge portion of the spindle assembly. A steering gear is coupled with a second end of the steering rod and configured to move the steering rod, such that the spindle assembly rotates with respect to the upper and lower suspension arms. The leading-edge portion is configured to exert primarily tensile forces on the steering rod during travel over rough terrain.
