Abstract

A vehicle for moving on the ice of water bodies, comprising a displacement hull, a crew room, steering, an engine, sliding bearings and a mover in the form of wheels with anti-skid elements, characterized in that the sliding bearings are made in the form of skates mounted on the sides of the displacement housing in one planes with narrow wheels of the mover, while both ends of the skates are bent up.

Description

The solution relates to floating vehicles and can be used as a safe means of transportation on the ice of large lakes and reservoirs. The main danger for vehicles on the ice of water bodies are stains and wormwoods with thin ice, which are not visually distinguishable under the snow among strong ice fields. Every year, dozens of fishing motorbikes, cars and snowmobiles across the country fall under the ice for this reason.

Safe vehicles for driving on the ice of water bodies are known. Such is a floating snowmobile (US patent No. 6595812 according to IPC B63H 21/175 of 2002) containing a displacement casing, a caterpillar mover with anti-skid elements and sliding ski supports.

When driving on snowy ice, snowmobiles with caterpillars and skis pre-crush and compact the snow layer on ice to provide the necessary grip on the ice surface, which consumes a significant part of the engine power. So a serial snowmobile on snowy ice compacts a track of snow up to 900 mm wide: 500 mm - a caterpillar plus two skis of 200 mm each.

Closest to the claimed device is a vehicle for movement on ice, snow and water (RF patent No. 2170181 IPC B60F 3/00 of 2000), containing a displacement casing mounted on skid-mounted ski or snow supports, front some of which are bent up, equipped with built-in heaters; as a mover, a system of studded wheels located at the rear of the hull with blades used when moving along a thick layer of snow and water is used as slabs in wheeled motor ships; the wheel system is pressed to ice with a special clamping device. When this vehicle is moving, heated supports sliding on the surface of the snow - skis compact and melt snow, and the wheel system with blades - steamer plates, crushes and digs snow to ice to ensure adhesion to the surface under the influence of the pressure device. The presence of a special clamping device complicates the design of the vehicle, and crushing snow with a system of wheels and skis, melting with skis requires certain energy costs. The disadvantages of this vehicle also include the difficulty of reversing, since the rear ends of the skis are not bent and when moving backwards will rest against irregularities on the surface of the ice.

The purpose of the proposed technical solution is to eliminate the above disadvantages, increasing the efficiency of the vehicle.

This goal is achieved by the fact that skates mounted on the sides of the displacement hull in the same plane as the narrow wheels of the propulsion device are used as the vehicle’s sliding supports, while both ends of the skates are bent up. When moving both forward and backward, the skates and wheels follow each other along narrow ruts, cutting through the weight of the vehicle a layer of snow (s) to ice (l) - Fig.2. Thus, the necessary contact of the supporting elements of the vehicle with the surface of the ice is provided practically without preliminary compaction of the masses of snow, in contrast to the known analogues.

The technical result of the considered technical solution consists in the possibility of reducing energy consumption when the vehicle is moving on snow-covered ice.

Figure 1 and 2 presents sketches of views of the vehicle side and front. The device comprises a buoyancy displacement hull 1 with a crew room 2, steering 3, engine 4. On the sides of the hull there are ice skates 5, both ends of which are bent upwards, in the same plane as narrow wheels 6, equipped with anti-skid elements 7. Dimensions of the skates and wheels are selected depending on the typical thickness of the snow cover in the region of application of the vehicle. In the design, it is possible to use serial units from cars and motor vehicles - engine, steering, front and rear suspension of cars. The displacement hull can also be selected from the number of serial small-sized vessels, or specially made. The complete set of the device is also suitable for wide skis, both ends of which are bent up, and voluminous wide low-pressure wheels, if necessary, installed instead of skates and narrow wheels.

The vehicle operates as follows:

- when leaving on ice without snow, a vehicle on skates and wheels with anti-skid elements provides comfortable and safe movement, not inferior to other modes of transport;

- when leaving on snowy ice, the skates and narrow wheels of the vehicle mounted in the same plane follow each other along narrow gauges - Fig. 2, cutting through the weight of the vehicle the snow layer (s) to ice (l) with virtually no crushing and compaction of the masses snow, thus making it more economical than other modes of transport on ice. With the onset of force majeure climatic changes, namely: an increase in the thickness of the snow cover above the calculated one, the formation of an ice crust on the snow surface, a decrease in the strength of ice during warming - it is possible to replace skates with wide skis, narrow wheels with wide, voluminous, low pressure. Thus, the vehicle is transformed into an ordinary, but floating snowmobile, not inferior in efficiency and economy to other modes of transport. The design of the vehicle in question also makes it possible to overcome other possible difficult situations on ice. When moving along sections of hummocked ice, overcoming humidified cracks between ice floes, an expedient pattern of movement is to reverse, at minimum speed. Upon entering a snow-covered wormwood with thin ice, ice skates and wheels will gently cut through the ice, and the car will be afloat. With the help of a hook, a cat’s anchor and a rope, the machine is pulled back to the edge of strong ice, then using the reverse gear, cable and winch, the vehicle is pulled out of wormwood onto solid ice.
