Abstract: An all-terrain vehicle including a frame having longitudinally-spaced ends defining a first longitudinal axis, and an engine supported by the frame. The engine includes a crankshaft defining a second longitudinal axis substantially parallel to the first longitudinal axis.

Abstract: A tracked ATV includes a frame, a track coupled to the frame, and a power source supported by the frame and drivingly coupled to the track. The tracked ATV further includes a steering and drive assembly, which has a first hydraulic pump coupled to the tracks for large radius turns. The steering and drive assembly also has a second hydraulic pump coupled to the tracks for small radius turns.

Abstract: A three wheeled vehicle is disclosed having a vehicle frame with a frame sidewall providing a substantially flat surface, with recesses in the flat surface. Alignment arms have inner ends and outer ends, where the inner ends are mounted to the frame sidewall, and the outer ends mount a wheel hub. The inner ends have couplings with pivotal portions and fixed portions, the pivotal portions being at least partially positioned within the recesses, and the fixed portions being attached to the substantially flat surface.

Abstract: An independent rear suspension for a vehicle having a chassis and a pair of rear wheels including a pair of IRS units. Each IRS unit includes an X-shaped lower control arm with a forward pivot connection to the chassis in front of the centerline of the driven sprocket and a rearward pivot connection behind the centerline, and a camber link connected to the chassis at a single pivot connection behind the centerline. Each IRS unit also includes a shock absorber coupled with an anti-sway bar to the lower control arm at a mount, and including a secondary spring in series with a main spring.

Abstract: A non-pneumatic tire is disclosed where a resilient wheel is mounted on a rim and the wheel has an inner ring, an outer ring and a plurality of flexible webs interconnected between the inner and outer rings. The flexible webs define openings in through the resilient wheel. The stiffness of the inner wheel at a position adjacent to the inner face is different than the stiffness of the inner wheel at a position adjacent to the outer face. This stiffness difference can be accomplished by providing inflated membranes in at least some of the openings or by molding the wheel with an asymmetric parting line. In addition, the wheels could be dynamically controlled by providing magnetically actuable membranes in some of the openings.

Abstract: A vehicle, including an independent rear suspension and a rear drive mechanism including a pair of dual offset joints mounted in a sprocket hub. Each dual offset joint is connected to a half shaft coupled to a wheel. A driven sprocket is connected to the sprocket hub at a location offset from a centerline of the vehicle. An external chain coupled to a drive sprocket coupled to the vehicle's engine and the driven sprocket to transfer rotational movement of the drive sprocket to the driven sprocket, thereby causing rotation of the sprocket hub, the dual offset joints, the half shafts, and the wheels.

Abstract: Various embodiments of variable rate stabilizer bars are disclosed, including apparatus, vehicle, and kit implementations. Embodiments may have first and second stabilizer bar members. Each stabilizer bar member may be adapted to be operatively coupled to a respective, opposite ground-engaging element of a vehicle. Each stabilizer bar member may be configured to experience a torque about their longitudinal axis upon movement of the respective ground-engaging element relative to the vehicle when operatively coupled to the ground-engaging elements. Embodiments may have a torque transfer regulator, which may be operatively coupled to both stabilizer bar members. The torque transfer regulator may be configured to transfer a portion of the torque experienced by one of the stabilizer bar members to the other stabilizer bar member. Some embodiments may provide for active control of the degree of torque transfer from one ground-engaging element's suspension system to the other.
