A rail brace system is designed for use with a snowmobile monorail. The rail brace system includes a brace having a first end, a second end, a length extending from the first end to the second end, a top side, a bottom side, a height extending from the top side to the bottom side, an inner surface, an outer surface, and a width extending between the inner surface and the outer surface. The inner surface is shaped complementary to a first side of a monorail of a snowmobile. The brace includes an opening extending through the width. The brace extends towards the second end to provide support to the monorail. The opening is positioned along the length of the brace to be concentric to a suspension mount hole of the monorail and the outer surface around the opening is configured to provide a mounting surface for a suspension arm.

An electric motor, drive, and assembly for a tracked vehicle. The assembly including an electric motor, a cylindrical housing encircling the electric motor and adapted for rotation about the motor, and a drive sprocket. The drive sprocket is coupled to the housing and having teeth to generally engage a track of the tracked vehicle.

A skid frame for a snowmobile is disclosed including a generally planar skid surface extending between front and rear idler wheels. The front and rear idler wheel are offset from one another and define a longitudinal direction. A track encircles the skid frame having the skid surface positioned over a center of the track such that a major longitudinally extending portion of the track that is coextensive with the skid surface has first and second unsupported lateral portions on either side of the skid surface. The first and second unsupported lateral portions extend in the horizontal direction at least 25 percent of a width of the track. A suspension arm member may mount the skid rail and include mount portions for mounting to a tunnel and spanning a distance at least twice the width of the longitudinal beam.

The invention is related to the class of small-scale tracked transportation vehicles, which can be used for towing a person and cargo using a sledge, for example. The motorized towing vehicle comprises a frame supporting a caterpillar drive, a platform supporting an engine with a transmission, a luggage space, an assembly for connecting to the object being towed object, a control device, and an object being towed. The caterpillar drive includes a caterpillar track, a metal subframe, a driven shaft and a driving shaft with pinions, and torsion-type wheel bogie. The control device consists of a steering wheel with handles and controls. The object being towed comprises a driver's workplace. The frame consists of a platform and a rigid framework enclosing the platform along the entire perimeter, including the luggage compartment with an additional luggage space above. The design of the frame and platform is asymmetrical relative to the track because of an extension of the platform in one direction. The subframe is in the form of metal side plates connected to the frame with brackets bent into an S-shape. The subframe plates accommodate a track tightening mechanism in the form of an eccentric and self-aligning bearings. An all-weather hood is used for protecting the engine and luggage space. The road performance of the motor towing vehicle has been improved.

A snow vehicle comprises a steering assembly, an endless track system, an engine system to power the endless track system and a platform adapted to be stood on by a rider or riders. The platform has a surface made of an anti-slip material, and the snow vehicle has a generally lower center of gravity thanks to its special structure, which facilitate safe operation for the rider.

The present disclosure provides a snow transport system with a frame comprising a base plate, a pair of opposed side plates mounted on opposed sides of the base plate, and a plurality of cross members extending between the side plates. A pair of convex lower track slides are mounted on lower portions of the pair of opposed side plates, and a pair of convex upper track slides are mounted on upper portions of the pair of opposed side plates. A drive wheel is mounted at an upper front portion of the frame, and an idler wheel mounted at a lower rear portion of the frame. A continuous track is wrapped around the drive wheel, the convex lower track slides, the idler wheel and the convex upper track slides. A motor assembly is mounted within the frame, and connected to the drive wheel through a transmission assembly. A push arm assembly is mounted to one side of the frame, the push arm assembly extending forwardly from the frame and having a push bar portion and user controls at a forward end thereof.

A snowmobile includes a frame, a tunnel, a seat, an endless track, at least one ski, a handlebar, a cowling defining an engine compartment, an engine, a continuously variable transmission (CVT) operatively connecting the engine to the endless track, and a pulley guard assembly disposed over at least a portion of the CVT. The CVT includes a primary pulley, a secondary pulley, and an endless flexible member operatively connecting the primary pulley to the secondary pulley. The pulley guard assembly is disposed between the CVT and a lateral side of the cowling, and defines an air inlet. The air inlet fluidly communicates with a space defined between the pulley guard assembly and the lateral side. In some implementations, the cowling defines an air inlet. In some implementations, an air duct fluidly connects the air inlet of the cowling to the air inlet of the pulley guard assembly.
