A ski system and a track system for a vehicle. The ski system includes a ski and a ski mount to connect the ski to the vehicle. The track system includes a track-engaging assembly and a track disposed around the track-engaging assembly. The ski system and the track system may be designed to enhance travel of the vehicle on the ground, including to facilitate banking of the vehicle (e.g., to turn, on a side hill, etc.), steering of the vehicle by turning the ski system, and/or moving on harder snow (e.g., packed snow).

A track system for traction of a vehicle (e.g., a snowmobile, a snow bike, an all-terrain vehicle (ATV), an agricultural vehicle, etc.). The track system comprises a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track system may be configured to enhance traction of the vehicle on the ground, such as by maintaining proper contact on the ground when the vehicle is leaned (e.g., for steering and/or over uneven terrain) and/or when the track system is subject to other loading that would otherwise tend to reduce tractive forces that it generates. For example, the track system may be configured such that, when the vehicle travels on the ground, a surface of the track-engaging assembly in contact with a bottom run of the track is movable relative to a frame of the vehicle to change an orientation of the surface of the track-engaging assembly in contact with the bottom run of the track relative to the frame of the vehicle.

The subject invention provides a snowboard that is propelled over the snow by a battery powered motor/wheel array. The preferred embodiments include a pair of motor/wheel arrays disposed on both sides of the board, on which are fitted specialized snow propellers designed for various snow conditions. The motor and wheel array are attached to the snowboard with a universal mounting plate, which utilizes any snowboard's standard binding mounting holes or channels. The motor/wheel array can be mounted to the board with L shaped brackets, or alternatively with spring loaded hinges. The motor/wheel arrays can be elevated with spacers, which position the wheels slightly lower than the deck of the board to provide traction during propulsion. Shock absorbers can also be utilized to provide downward force to the motor/wheel arrays, and allow upward articulation to accommodate inclined terrain.

The invention relates to a sporting device (1), in particular a touring ski assembly. The sporting device (1) comprises a sliding body (2) on which a bottom side (3) is designed as a sliding surface (4). Furthermore, the sporting device (1) comprises a binding apparatus (6) disposed on the top face (5) of the sliding body (2) for fastening to a sporting shoe (7) of a user (8) in such a way that the fastening can be released as and when necessary, a circulating belt (13) having a first segment (14) for establishing a relative motion between the sliding body (2) and the ground (12) and a second, returning segment (15), as well as a drive apparatus (17) and at least one first deflecting apparatus (18) for the belt (13). The first segment (14) is disposed next to the bottom side (3) of the sliding body (2) and the second, returning segment (15) is disposed next to the top face (5) of the sliding body (2). At least the majority of the length (9) of the sliding body (2) is surrounded by the circulating, intrinsically closed belt (13). By means of this design, a user can be supported with regard to his advancing movement, in particular the overcoming of ascents and mountain routes can thereby be made easier, such that the body force or performance capacity to be applied by the user can be lower.
