Description

The invention relates to vehicles with high cross-country ability, and more precisely to those that are equipped with rotor-screw propellers and are intended for movement where there is no solid soil and asphalt, but there is impassable tundra, swamps, swamps, not frozen rivers, deep snow.

A cross-country vehicle is known according to US patent No. 3397668, class 115-1, 1967, comprising an internal combustion engine mounted on a housing that is mounted on rotor-screw propellers with hollow screw ridges connected to the exhaust pipe of the engine.

The main disadvantages of this vehicle is that:

- due to the excessive height of the ridge during movement, the mover does not compact, but loosens the snow, performing useless work, spending additional power;

- when driving, significant shock loads on the screw ridge are perceived due to its rigid mounting on the mover;

- additional power losses due to the fact that the exhaust gases from the engine to the exhaust pass a significant distance in the maze;

- the design of the mover is complex and time-consuming to manufacture.

Also known is a cross-country vehicle according to copyright certificate No. 1118578, B62D 57/00, B60F 3/00.

The disadvantage of this vehicle is also that:

- due to the excessive height of the ridge when the vehicle is moving, its mover does not condense, but loosens snow, performing useless work, spending additional power;

- when driving, significant shock loads on the screw ridge are perceived due to its rigid mounting on the mover;

- additional power losses due to the fact that the exhaust gases from the engine to the exhaust pass a significant distance in the maze;

- the design of the mover is complex and time-consuming to manufacture.

The purpose of the invention:

1. To improve the driving performance of a vehicle with a rotor-screw propulsion.

2. To reduce the shock loads arising during the movement of the vehicle on the propulsion elements.

3. Simplify the design of the mover.

4. To reduce the complexity of manufacturing a mover.

5. Increase maintainability of the mover.

6. To reduce the load and power costs of the vehicle when moving it away.

7. Eliminate the sticking of snow, dirt and other fractions to the working body of the mover.

This goal is achieved by the fact that the screw ridges are made in the form of replaceable tension springs installed with a gap over hollow, with a smooth surface, cylindrical movers, forming one, two, three or four-way screw with them and fixed at one end in front along the direction of travel with parallel kerchiefs and clamps, while on the axis of attachment of each cylindrical mover rear mounted propeller.

Replaceable tension spring can be made of trapezoidal spring steel, round or rectangular cross-section.

Thus, the claimed vehicle is a cross-country vehicle meets the criterion of "Novelty."

Signs that distinguish the claimed technical solution from the prototype in other technical solutions of this technical field are not identified, which allows us to conclude that the claimed vehicle is a cross-country vehicle meets the criterion of "existing differences".

Figure 1 shows the proposed means of transport high cross, side view; figure 2 is a view a of figure 1; figure 3 is a section bb In figure 2; figure 4 - state of the propulsion in statics; figure 5 - state of the propulsion in motion; figure 6 - replaceable tension spring trapezoidal section, General view, in a perspective view; Fig.7 is a removable tension spring of circular cross section, a General view, in a perspective view; on Fig - interchangeable tension spring of rectangular cross section, General view, in a perspective view.

The high-cross-country vehicle (Fig. 1) contains an internal combustion engine 1 mounted on a housing 2, which is mounted on two rotor-screw propellers 3 with screw ridges 4, which are made in the form of interchangeable tension springs 5 installed with a gap over the hollow, with smooth surface 6, of cylindrical propulsors 7, forming with them one, two, three or four-way screw and fixed with one end 8 in front along the direction of movement with the help of parallel scarves 9 and clamps 10, while on the axis 11 (figure 1) fastening dogo cylindrical mover 7 downstream of movement is mounted a propeller 12.

Replaceable tension spring 5 can be made of spring steel trapezoidal 13, round 14 or rectangular 15 section.

When starting off a vehicle with a high cross-country ability, containing an internal combustion engine 1 mounted on a housing 2 that is mounted on two rotor-screw propellers 3 with screw ridges 4, which are made in the form of interchangeable tension springs 5 installed with a clearance “S” on top hollow, with a smooth surface 6, cylindrical movers 7, forming with them one, two, three or four-way screw and fixed with one end 8 in front along the direction of movement with the help of parallel scarves 9 and clamps 10, lower turns mennoy tension springs 5 are pressed against the smooth surface 6 of the cylindrical propeller 7 under the influence of the vehicle mass, and the upper windings will have a clearance «S», wherein the pitch of removable tension spring 5 is equal to t _1.

After the vehicle begins to move, the replaceable tension spring 5, under the influence of the component forces and friction forces acting on it, will begin to stretch until its upper turns press against a smooth surface 6, while the step of the turns increases and is equal to t ₂ , i.e., t ₂ > t ₁ .

Taking into account that during the movement of the vehicle, the forces acting on the replaceable tensile spring 5 constantly change due to the relief, its pitch will also change, thereby mitigating the shock loads that occur, for example, when the turns of the replaceable tension spring 5 come into contact with stones , tree roots or other obstacles.

In addition, this state of the replaceable tension spring 5 prevents the buildup of snow, dirt and other fractions on the smooth surface 6 of the cylindrical mover 7.

Depending on the season, the state of the relief on the cylindrical mover 7 can be installed interchangeable tension springs 5 as a trapezoidal 13, and a round 14 or rectangular 15 section.

For example, when moving on ice, it is advisable to install replaceable tension springs 5 of a trapezoidal 13 section, and in the snow - a rectangular 15 section.

On weak soils, on sand, replaceable tension springs of 5 round 14 cross-section are suitable.

The design of the cylindrical propulsors 7 allows you to install various kinds of combinations of interchangeable tension springs 5.

Given the fact that the cross-sectional height of the profile of the replaceable tension spring 5 has a significantly lower height than the crest of the prototype, the propeller 12 mounted on the axis 11 of the attachment of each cylindrical mover 7 in the rear in the direction of travel, provides a means of transporting vehicles through water barriers.

The replacement of interchangeable tension springs 5 is as follows:

- free the ends 8 of the replaceable tension springs 5 from the clips 10, removing them from the holes of the parallel scarves 9;

- on its own, the vehicle is moved (passing) forward until all interchangeable tension springs 5 mounted on the cylindrical mover 7 come off it;

- in front, one new replaceable tension spring 5 push its rear end under the cylindrical mover 7 and drive forward until the replaceable tension spring winds onto the smooth surface 6 of the cylindrical mover 7;

- the retainer 10 in front lock interchangeable tension spring 5.

The installation of the remaining interchangeable tension springs 5 is carried out as described above.

The application of the proposed means of high-traffic vehicles will allow:

1. To improve the driving performance of a vehicle with a rotor-screw propulsion.

2. To reduce the shock loads arising during the movement of the vehicle on the propulsion elements.

3. Simplify the design of the mover.

4. To reduce the complexity of manufacturing a mover.

5. Increase maintainability of the mover.

6. To reduce the load and power costs of the vehicle when moving it away.

7. Eliminate the sticking of snow, dirt and other fractions to the working body of the mover.
