A wheel system for a snowmobile ski provided with an adapter plate secured thereto is provided. The wheel system includes an actuating assembly having a support plate removably connectable to the adapter plate to enable connection and disconnection of the actuating assembly from the adapter plate and from the snowmobile ski. The wheel system also includes an actuator pivotally connectable to the support plate and operable between an idle configuration and an engaged configuration. The wheel system further has a wheel coupled to the actuator and adapted to be positioned in a raised position spaced from a ground surface when operating the actuating assembly in the idle configuration, and a lowered position in engagement with the ground surface when operating the actuating assembly in the engaged configuration.

A lift assembly comprises a frame work extending between a first lift side and a second lift side and a frame support system wherein a portion of the frame support system includes a ski system that extends under the frame work in the direction of travel such that a continuous sliding surface is presented to slide the frame over obstacles.

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 device for attaching to a ski of a snowmobile includes first and second spaced apart legs. Each leg has a ski engaging portion proximate a second end that is configured to engage a bottom surface of the ski proximate outer edges thereof. The device includes at least one wheel attached to the first and second legs between the first end and the second end and a cross bar that attaches the first and second legs proximate first ends thereof. The device includes a lever arm extending from the cross bar between the first and second legs wherein the lever arm is configured to be angularly positionable relative to the first and second spaced apart legs. A handle is attached to a distal end of the lever arm and has a surface configured to engage a tip end or a ski handle of the ski. The device includes a retaining member attached to the handle that is configured to engage the ski handle, wherein when the ski engaging portions engage a bottom surface of the ski and the retaining member engages the ski handle, the ski is elevated and the at least one wheel engages the ground surface such that the skis do not contact the ground surface as the snowmobile is moved.

The vehicle includes: a chassis which includes a front cross-member and a rear cross-member; a nacelle receiving a person or a load, pivotally mounted relative to the central part of the cross-members about a substantially longitudinal hinge axis, the center of gravity of the nacelle being situated below said hinge axis; a front train and a rear train, each including two movement supports on the ground, each movement support being connected to the end part of the corresponding cross-member by a connecting system; the cross-members, situated in the upper part of the nacelle, being separate pieces linked together only by the nacelle, via the hinge axis, so as to be able to pivot about the hinge axis independently of one another.
