Description

The invention relates to devices designed to transform wheeled vehicles for movement on snow cover.

A ski is known in the art as part of a kit for converting a vehicle into a tracked snowmobile, 40 inches long, made of steel and having a central ridge or double ridges on each side of the ski that are approximately 1 inch high. The ski preferably has a width of 5.5 inches. It additionally includes a stiffener, which can also be used as a handle. The ski / strut assembly is preferably attached to the front fork assembly of the vehicle and includes struts that are mounted to rotate the position of the ski in a vertical plane. Racks made of steel alloy or aluminum. [Patent for invention No. US7357201, publication date 04/15/2008]

The closest analogue of the claimed utility model is a snowmobile ski containing a base having an upper surface for connection with a snow vehicle and a lower surface for sliding on snow and ice, which contains the first keel running along the first side edge of the base, the second keel running along the second lateral edge of base, third keel extending along the longitudinal axis of the base, where the third keel extends downward from the base for a distance greater than the first keel containing a pair of directional down ridges along the side edges of the elongated hardened member. The distance between the pair of downward directed ridges is in the range of 0.25 to 0.5 inches. [Application for invention No. US2015259032, publication date 09/17/2015]

The main disadvantage of the known devices is the low controllability when driving in deep snow and the poor stability of the vehicle when cornering, due to the design features of the ski.

The technical problem, the solution of which is claimed by the claimed utility model, is to increase the maneuverability and stability of the vehicle when making turns.

The technical result consists in increasing the maneuverability of a vehicle using a ski to move on snow.

The essence of the claimed utility model.

A ski for driving a two-wheeled vehicle in the snow contains a base, a mount and a handle. The mount comprises a housing, a connection to the base of the ski, and a mount to the feathers of the fork of the vehicle. On the lower surface of the base of the ski, side and central keels are made, equipped with skates, while the height of the central keel is greater than the height of the side keels. Unlike the closest analogue, the side surface of the base of the ski, side keels and skates located on them are made with a radial bend with narrowing in the central part, while the side keels are inclined to a vertical plane. The attachment to the feathers of the vehicle plug is made with the possibility of adjusting the departure angle.

The base of the ski can be made of polyethylene with a molecular weight of 4.5 million g / mol. This provides increased wear resistance of the ski and improves glide due to maintaining the strength and elasticity of the material at low temperatures up to -200 0 C. Skates can be made of sheet steel with high-frequency hardening of the working edge, the skates can be attached to the base of the ski detachable, for example, with bolts, in order to ensure the possibility of their replacement. The lateral keels are located along the lateral longitudinal sides of the base, and the central keel is located along the longitudinal axis of the base. Skates located on the lateral keels have a L-shaped profile. The ridge located on the central keel has a U-shaped profile and a bend in the vertical plane, made in such a way that the front of the ridge is recessed into the surface of the keel, which ensures smooth passage of possible obstacles under the snow. The difference between the height of the skate located on the central keel and the skates located on the lateral keels can be from 25 to 35 mm.

The inclination of the side surface of the base of the ski and side keels relative to the vertical plane can be from 5 to 15 ° , while expanding the space limited by the side keels, the ability of the ski to be on the surface of the snow cover is maintained while increasing the stability of the vehicle. The radius bend of the side surface of the base of the ski and side keels provides a narrowing in the central part of the ski of no more than 5%, while the skates located on the side keels repeat the radius bend of the side surface of the ski and keels. When the direction of movement changes, the motorcycle tilts towards the turn, while the lateral keels slide due to the radius bend, describing the circle with a small turning radius, thereby increasing the vehicle’s maneuverability. The keels form longitudinal tunnels on the lower surface of the ski to move the snow mass during movement. The radial bend of the side surface of the ski and the side skates provides narrowing of the tunnels in the middle part of the ski, due to which the snow is compacted in the middle part of the ski, which ensures a decrease in the ski's warmth when driving in deep snow.

The mounting body is provided with two stiffening plates on the sides, and the connection to the base of the ski is made with the possibility of changing the position of the base of the ski in a vertical plane along its longitudinal axis. The ability to adjust the angle of departure can be provided by fastening to the feathers of the fork in the form of two fixing clamps, each of which is a collapsible ring with connecting elements and a protrusion, on which are holes for mounting to the stiffening plates, while the stiffening plates are also provided with holes for mounting fixing collars. Additionally, holes for installing spacers can be made in the protrusions and stiffening plates to further fix the position of the feathers of the fork. The mounting body and stiffening plates contain holes for accommodating the standard axis of the vehicle wheel and can be equipped with transitional adapters for it. The case for attaching the ski to the motorcycle fork can be made of polyethylene with a molecular weight of 4.5 million g / mol, the stiffening plates, fixing clamps and connecting elements can be made, for example, of duralumin, due to which the mount is highly durable, able to withstand ultra-low temperatures without changing properties and has high torsional rigidity. The departure angle is adjusted by shifting the fixing bolts in the corresponding holes of the clamps and stiffeners, thereby changing the position of the ski attaching to the feathers of the fork relative to the motorcycle fork and the departure angle, respectively. The number of holes on the stiffeners can vary depending on the required accuracy of adjusting the angle of departure. Adjusting the angle of departure of the mount provides the ability to calibrate the vehicle depending on weather conditions, namely, it provides increased controllability of the vehicle when driving in snow of different quality.

The above essential features ensure the achievement of a technical result to increase the maneuverability of a vehicle using a ski for movement on snow, which allows us to conclude that the claimed utility model meets the patentability criterion of "novelty."

The inventive utility model can be performed by known methods from known materials, which ensures its compliance with the patentability criterion of "industrial applicability".
