An apparatus for adapting a single-track vehicle for use on a chairlift is provided. A first adapter portion may be configured to be removably coupled to at least a portion of a single-track vehicle. A second adapter portion may be pivotably coupled to the first adapter portion. A space formed between the first adapter portion and the second adapter portion may be configured to receive at least a portion of a chairlift seat of a chairlift.

A snow bike's three (3) piece chassis includes a frame disposed about the chassis' center. The chassis also includes an elongated, front fork, rotatably secured at an upper end of the frame's front end. A lower end of the front fork carries an elongated front snowboard. Lastly, the chassis includes a spring loaded swingarm that is pivotally secured to a rear end of the frame furthest from the front fork, and projects rearward therefrom. A distal end of the swingarm carries an elongated rear snowboard. A hole, that pierces the rear snowboard adjacent to its attachment to the swingarm, receives one end of a V-shaped plate that is rotatable so the plate's end projects beneath the rear snowboard into snow therebeneath. A coil spring, disposed between the swingarm and the V-shaped plate, draws the V-shaped plate's projecting end out of snow.

A trailer for being pulled by a motor vehicle, the trailer comprising a chassis having a front section, a first side section and a second side section, wherein the front section comprises coupling means for being coupled to a motor vehicle. The trailer further comprises a first and a second bogie, each bogie having two wheels, the first bogie being connected to the first side section of the chassis in a first pivoting coupling and the second bogie being connected to the second side section of the chassis in a second pivoting coupling. The trailer comprises a first and a second runner extending in the driving direction of the trailer and the first and second runners are moveable between an on-road position and an off-road position, and the first runner is mechanically coupled to the first bogie and the second runner is mechanically coupled the second bogie so that the runners may pivot relative the chassis.

A trailer system for transporting multiple adult passengers and/or supplies over harsh terrain (e.g., snow, ice, wetland, etc.) when towed behind a vehicle. The trailer system includes a cabin, first and second skis, and first and second suspension assemblies. The suspension assemblies connect the skis, respectively, with the cabin. The suspension assemblies incorporate multiple pivot points that effectively isolate the skis from cabin, and promote true “tracking” of the trailer system relative to the towing vehicle. In some embodiments, the cabin has a highly buoyant construction, allowing the trailer system to float in water.

The present specification relates to a snowmobile. The upper arm includes two proximal portions connected to the vehicle frame and the upper arm extends outwardly from the two proximal portions in the vehicle width direction and the upper arm is connected to the knuckle. The two proximal portions are rotatable so that the knuckle and the skis can move up and down relative to the vehicle frame. The axis Ax2, passing through the rotation center C2 of the two proximal portions of the upper arm, goes through a position of the rotation center of the secondary shaft or through a position above the rotation center of the secondary shaft. This structure can reduce the force acting on the vehicle body frame via the upper arm and prevent an increase in the force.

Various embodiments of a snowmobile are disclosed. The lower arm is arranged below the upper arm. The lower arm includes proximal portions and connected to the ski support frame. The lower arm extends outwardly from the proximal portions and in the vehicle width direction and connects the ski support frame and the ski. The proximal portions and of the lower arm are positioned higher than the lower end of the engine. At least a portion of the lower arm is positioned higher than the rotational center of the crank shaft. This structure can prevent the center of gravity of the vehicle body from becoming high and reduce running resistance when the vehicle traveling in deep snow.
