Description

The proposed utility model relates to terrain vehicles with increased cross-country ability, intended for driving over rough terrain and overcoming possible water barriers on its way.

Widely known off-road vehicles designed for movement on snow cover, wetlands, etc. One of these vehicles, described in the application for a patent for invention US 2002155765, is selected as the closest analogue of the proposed technical solution. US2002155765 describes a tracked off-road vehicle, including a propulsion system with an internal combustion engine, auxiliary equipment of a propulsion system, steering means, a caterpillar mover located on a welded housing with an integrated power frame. A well-known tool can move both over rough terrain, snow, wetlands, and overcome water barriers (it is obvious that overcoming water barriers is an important factor determining the choice of an all-terrain vehicle designed to overcome impassable swamps or shallow water bodies). The buoyancy of a vehicle known from US200215576 is ensured by the execution of track tracks from low density materials, i.e., ensuring the all-terrain vehicle is kept on the surface of the water. It is obvious that the caterpillar mover made in this way will have low reliability due to the frequent damage to the tracks of the tracks during movement, and especially during night and day temperature extremes. In addition, the body of a well-known all-terrain vehicle cannot be used with the necessary efficiency on rough terrain due to a collision with bumps, stumps, etc. obstacles.

The proposed solution eliminates the disadvantages of the known solutions and provides increased maneuverability and maneuverability of an off-road vehicle.

In particular, provided

- the ability to move without loss of speed and ride quality, both on country roads, and on snow cover, wetlands, etc. impassable surfaces;

- the ability to force difficult and impenetrable swamps and water barriers (ponds, floods during floods);

- the possibility of access to a steep coast, movement on the terrain covered with light forest, shrubs, tall grass, reeds, etc .;

- the possibility of movement without loss of driving performance along the slope and up the slope.

The above result is achieved by using a crawler-mounted snow and swamp vehicle, which includes a propulsion system with an internal combustion engine, auxiliary equipment of the propulsion system, steering means, a caterpillar propulsion unit, and a welded housing with an integrated power frame. According to the proposed solution, the bow of the casing and the caterpillar mover form a single surface hanging over the surface of the snow and swamp, the body is sealed with the formation of a displacement cavity and the location of the propulsion system in the rear part, while the caterpillar mover is located on a rigid frame with the location of the drive shafts in its front the upper part and with a decrease in height from the bow to the tail of the snow and swamp. Additionally, in the bow of the casing of the snow and swamp are located the installation of an outboard motor. The snow and swamp vehicle may include a height-adjustable raised floor, forming a flat platform in the raised position. Most of the bottom - made completely flat.

The proposed solution is illustrated in the drawing, which shows the layout diagram of snow and swamp.

The caterpillar snow and ice vehicle includes a propulsion system 1 with an internal combustion engine, auxiliary equipment of the propulsion system (starter, hydraulic brakes, etc. not shown in the diagram), tractor-type steering means 3, tracked propulsion unit 2 made of reinforced rubber, welded body with built-in power frame 7. The nose of the casing 7 and the caterpillar mover 2 form a single surface 4, hanging over the surface of the movement of snow and swamp. The housing 7 itself is sealed with the formation of a displacement cavity and the location of the propulsion system 1 in its rear part. The caterpillar mover 2 is located on a rigid frame 5 with the location of the drive shafts 6 with chain drives in its front upper part and with a decrease in height from the bow to the tail of the snow and swamp. In the rear of the hull can be located the means of installing an outboard motor (not shown in the diagram). In the design of the snow and swamp vehicle, a height-adjustable raised floor can be provided that forms in a raised position a flat platform on which a frame 9 for the awning can be provided, in which case the snow and swamp vehicle can also be used for temporary overnight.

The snow and swamp vehicle is intended for individual use: transporting 1-2 passengers with a small load. Caterpillar mover 2 provides the movement of snow and swamp roads on country roads, and on snow cover, wetlands, etc. impassable surfaces. The use of typical materials used in the construction of tracks in the construction of the snow and swamp vehicle eliminates accidental damage and deformation of the tracks under extreme operating conditions, differences in day and night temperatures, etc. The sealed displacement design of the hull allows you to use the snow and swamp path if necessary as a watercraft, that is, it will allow you to force water barriers (most importantly, this is the advantage of the design of the snow and swamp path when crossing difficult and impassable swamps, spills during floods and floods). The rigid frame 5 of the caterpillar mover 2 without suspension eliminates the caterpillar crashes. The design of the caterpillar mover 2 with a decrease from the bow to the tail allows you to move through the water with the help of caterpillars, self-cleaning the tracks and reduce wear on the drive chain drive stars.

With the movement of the snow and swamp vehicle, the location of the propulsion system 1 in the rear part of the snow and swamp vehicle, that is, when the center of mass of the structure is shifted to the tail part, overcomes steep climbs and movement along the slope. A single surface 4 formed by the bow parts of the hull 7 and the caterpillar mover 2 and the caterpillar engine with structures with a "slope" to the tail part provides access to the steep coast from the water, movement on the terrain covered with sparse forests, shrubs (with tree thickness up to 8 cm), tall grass, reeds, etc. When moving in such a terrain, surface 4 ensures that the snow and swamp walker collides with the obstacle to be overcome or is lifted up, thus the vegetation cover typical of wetlands, for example, will not serve as an obstacle to the movement of the snow and swamp path, while collecting and towing in front of the bow and snow swath is almost completely eliminated fallen trees, crumpled grass, moss, etc.

The snow and swamp vehicle of the proposed design showed high running quality during the operation of prototypes during movement over rough terrain, snow cover, and forcing water barriers.
