A snow vehicle is disclosed comprising a vehicle frame, a propulsion unit coupled to the frame, and a front ski steered by a steering mechanism. The snow vehicle has a chain coupling the sprocket of the propulsion unit and a chain tensioning device to take up the chain tension. The chain has a chain guide positioned below a lower run of the chain which directs the chain towards an upper run of the chain.

A track for traction of a vehicle e.g., a snowmobile, a snow bike, an all-terrain vehicle (ATV), etc.), in which the track may have features to enhance its traction, floatation, and/or other aspects of its performance, including to be lightweight, facilitate turning, enhance acceleration, reduce noise, adapt to different ground conditions, and/or provide other benefits.

A snow vehicle is disclosed comprising a vehicle frame, a propulsion unit coupled to the frame, and at least one front ski steered by a steering mechanism. The front of the vehicle includes a first front suspension and a second front suspension coupled to the ski. The rear suspension includes a bumper assembly preventing bottoming out of the rear suspension. The rear suspension is coupled to the vehicle frame such that the longitudinal spacing between the vehicle frame and rear suspension is adjustably controllable.

A conversion kit for a snow vehicle has a front assembly component, the front assembly component has a front ski, a bracket that is attached to the front ski, two extension arms that are pivotally attached to the bracket extending upwardly from the front ski, and a rear assembly component having a two or more adjacent members, a mount attached to the pivot unit, comprising a clamping attachment on one end configured to retain a section of the frame on another end, a ski attachment terminating each adjacent member, a pivot unit, comprising at two horizontal pivot bars pivotally connecting the adjacent members at its ends, and pivotally connected to the mount at a midpoint, wherein the one or more horizontal pivot bars move the adjacent members interdependently, and wherein each member extends from a common pivot unit and terminates at a ski attachment.

A motorcycle conversion kit for a three wheeled motorcycle wherein the conversion kit of the present invention is operable to transition the motorcycle so as to traverse across a snowy terrain. The conversion kit of the present invention includes a pair of ski assemblies that are operably secured to the front rotor assembly of the motorcycle. The ski assemblies include rotor movement inhibitors. A swing arm assembly is operably coupled to the frame and includes a front portion and a rear portion. The rear portion has rotatably mounted thereto a snow belt drive wheel. The show belt drive wheel is superposed a snow belt of a snow belt assembly wherein the snow belt assembly is secured to the frame of the motorcycle. The kit further includes a fuel cell bracket assembly having support members mounted on opposing sides of the frame and having a compartment rearward of the motorcycle.

A snow bike track assembly includes a frame assembly, at least one strut, an endless track, a plurality of top and bottom rollers, a skid rail assembly, a drive assembly, and a swing arm assembly. The frame assembly is configured to connect to a frame of a motorcycle in place of a rear wheel of the motorcycle. The at least one strut is connected to the frame assembly and configured to connect to the motorcycle frame in place of a rear shock of the motorcycle. The plurality of top rollers are mounted to the frame assembly and arranged to support the endless track. The plurality of lower rollers are mounted to the skid rail assembly and arranged to support the endless track. The drive assembly is configured to drive the endless track. The swing arm assembly is coupled between the frame assembly and the skid rail assembly.

A track kit for a vehicle (2), having two track assemblies (1,1′), each track assembly having an endless track (5), a front idler wheel (8), an intermediate support member (6) with at least one track engaging element (7), a rear idler wheel (9), a drive wheel (10), at least one swing arm (11,12) and a shock absorber connecting assembly (13,14), wherein the endless track (5) has an external side featuring ground lugs (15) for ground engagement and an internal side featuring drive lugs (16) for engagement with the drive wheel (10), and the internal side is circumferentially trained around and in contact with the front idler wheel (8).

An electric linear actuator and retractable wheel assembly configured for use on a snowmobile is provided. The assembly includes bracket or base member configured to be attached to a ski of a snowmobile. The base member supports a linear actuator which is activated to rotate a transfer plate. The transfer plate simultaneously slides and pivots around a transfer shaft which guides and limits the movement of the transfer plate. A wheel is attached to the transfer shaft such that the wheel is configured to retract and protract relative to the ski of the snowmobile allowing the wheel to be used instead of the ski when the snowmobile is traveling on rough surfaces.
