A snowmobile has a frame, a tunnel, at least one ski operatively connected to the frame, a motor supported by the frame, and an endless drive track operatively connected to the motor. The tunnel extends above the endless drive track and has a first part and a second part. The second part extends rearward from the first part. The first part is made of a first material. The second part is made of a second material that is resilient. The second material is different from the first material. When a downward force is applied to a rear end of the second part, the second part bends downward from an original configuration such that the rear end of the second part moves toward the endless drive track. The second part returns at least approximately to its original configuration after removal of the downward force.

A damping control system is provided for an off-road recreational vehicles having a suspension located between a ground engaging member and a vehicle frame and including at least one adjustable shock absorber having an adjustable damping characteristic based on an input from a sensor.

Steering control system for snow vehicles, suitable for equipping vehicles like snowmobile type or more specifically of the standing snowmobile style (1), with a basic configuration of, at least, two front skis (4a, 4b) and one drive track (3). The system acts on one or the other ski independently, and depending of the chosen path left or right, the rider can activate the left ski system or the right ski system using a mechanism that can be manual or assisted. This swing arms system (5a, 5b) and rotating ski spindle (6a, 6b) allow an easy and stable lateral tilt of the snowmobile, and besides generate a multiple and simultaneous orientation on the ski (4a) or (4b). All these factors gives the snowmobile high maneuverability and efficient control of the trajectory.

An electric snowmobile that can reduce a load locally applied to a body frame is provided. The electric snowmobile includes a body frame, a right ski and a left ski, a track mechanism, a steering shaft, an electric motor, and a battery. The body frame includes a shaft support frame that rotatably supports the steering shaft, a front frame that extends forwardly and downwardly from the shaft support frame, and a rear frame that extends rearwardly and downwardly from the shaft support frame. The battery is supported by the front frame and the rear frame such that at least a portion of the battery is disposed in a region formed by a line connecting the front frame, the rear frame, a lower end of the front frame, and a lower end of the rear frame in a side view.

A device for attaching to a ski of a snowmobile includes first and second spaced apart legs includes a ski engaging portion that is configured to engage a bottom surface of the ski. At least one wheel is attached to the first and second legs. A cross bar connects the first and second legs proximate first ends thereof. A lever arm extending from the cross bar and is angularly positionable relative to the first and second spaced apart legs. A retaining member 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.

A snowmobile has a gearbox having a first shaft, a second shaft, first transmission gears mounted to the first shaft and second transmission gears mounted to the second shaft. A driven gear mounted to the first shaft engages a forward drive gear mounted to a countershaft. In a first configuration: the first shaft is coupled to the countershaft; when rotating, a driveshaft rotates in a same direction as the countershaft; and configurable portions of the countershaft and second shaft are free of gears. In a second configuration: the forward drive gear is in selective free-spin engagement with the countershaft; a reverse drive gear mounted to the configurable portion of the countershaft is in driving engagement with the countershaft; an actuator selectively transmits rotary motion from the countershaft to the gearbox; a reverse driven gear mounted to the configurable portion of the second shaft meshes with the reverse drive gear.

A snowmobile assembly including a chassis and suspension system. The suspension system configured to allow a selected suspension travel. The snowmobile further including a cooling system assembly.

A snowmobile has a frame, a tunnel, at least one ski operatively connected to the frame, a motor supported by the frame, and an endless drive track operatively connected to the motor. The tunnel extends above the endless drive track and has a first part and a second part. The second part extends rearward from the first part. The first part is made of a first material. The second part is made of a second material that is resilient. The second material is different from the first material. When a downward force is applied to a rear end of the second part, the second part bends downward from an original configuration such that the rear end of the second part moves toward the endless drive track. The second part returns at least approximately to its original configuration after removal of the downward force.

Electric Powered Boots are a new compact and rugged motorized multi-terrain micro-vehicle for individual powersports, mobility for ground troops, or anyone who has difficulty in walking or running. For use on snow, sand, asphalt, hard dirt, or mud, electric powered boots elevate the prior teachings of motorized surf boots of U.S. Pat. No. 5,643,029 to the next level of fit, form, and function, by adding novel features and components in an innovative packaging arrangement that provides increased safety, functionality, and ergonomics during use on land.

A tracked vehicle may include a plurality of ground engaging members coupled to a frame through a plurality of suspensions, the plurality of suspensions including at least one adjustable shock absorber.
