Mover caterpillar machine is intended for the equipment of different vehicles, ranging from snowmobiles and all-terrain vehicles for rough terrain and ending motorcycles "creeper", transport to other planets, robots for demining.

This thruster will be able to work in the most unfit for normal transport regions in the search parties in the oil fields, agricultural lands, bringing minimal environmental damage the surface on which it moves.

Currently known drivers of tracked vehicles usually contain two caterpillar fabric. These paintings are a special case of the chain of transmission and, by definition, can only move forward or backward, as the caterpillar is not able to bend in the direction perpendicular to its movement. This feature of the chain of transmission is described, for example, in the book Dvernitsky. Fundamentals of machine design. Moscow, Uniic. "Educational literature", 1998, p.122: "Because the chain cross-section does not have the flexibility, the chain of transmission shafts must be parallel and asterisk are on the same plane". Therefore, tracked vehicles are usually made with two tracks. For turning such a machine, one caterpillar has to brake and the other to move around it. is it requires a lot of engine power, and causing great damage to the ground or road surface.

Known, for example, the propulsion of the vehicle designs of a Russian engineer Out, developed and manufactured in 1915 (the journal "Equipment and weapons" 2001, No. 9, p.15). The vehicle includes a support frame, broad-based crawler canvas, includes a hinged interconnected tracks with crests or coils, mounted with clearance relative to each other, and covering leading and guiding wheels, group, track rollers, and the rotation mechanism made in the form of two separate lateral wheel. The rotation of such propulsion is carried out by turning the two wheels with the stress and heavy loads. When testing the vehicle additionally had to accentuate the wooden poles in the ground.

Also known propulsion of the snowmobile (U.S. patent No. 2925873, CL VM 27/02 (naccl 180-5), publ. in 1960, containing the reference frame, broad-based crawler canvas, includes a hinged interconnected tracks with crests or coils, mounted with clearance relative to each other, and covering leading and guiding wheels, group, track rollers, and the rotation mechanism made in the form of two separate skis. The rotation of such propulsion is accomplished by reversal of these two skis with effort and high loads. However, the caterpillar due to the rotation around the vertical is through axis "loosens" the snow and the earth.

Also known mover "snow bike" (U.S. patent No. 3221830, CL VM 27/02 (naccl 180-5), publ. in 1965), containing the reference frame, broad-based crawler canvas, includes a hinged interconnected tracks with crests or coils, mounted with clearance relative to each other, and covering leading and guiding wheels, group, track rollers, and the rotation mechanism, made in the form of legs "biker" on both sides of the track surface. The rotation of such propulsion is accomplished by reversal of the Bicycle wheel, rigidly connected to the worm relative to the two skis on the feet muscular effort of the cyclist.

Also known mover "snow scooter" (U.S. patent No. 3252533, CL VM 27/02 (naccl 180-5), publ. in 1966), containing the reference frame, broad-based crawler canvas, includes a hinged interconnected tracks with crests or coils, mounted with clearance relative to each other, and covering leading and guiding wheels, group, track rollers, and the rotation mechanism made in the form of one independent skis. The rotation of such propulsion is accomplished by reversal of the specified skis with effort and high loads. At the same time as the ski, and the caterpillar is ripping the snow and earth to rotate around its vertical axis.

Most near them the technical nature of the proposed propulsion is propulsion of the snowmobile for U.S. patent No. 3404745, CL VM 27/02 (naccl 180-5), publ. in 1968, containing the reference frame, broad-based crawler canvas, includes a hinged interconnected tracks with crests or coils, mounted with clearance relative to each other, and covering leading and guiding wheels, group, track rollers, and the rotation mechanism made in the form of small separate skis.

The rotation of such propulsion is accomplished by reversal of the specified skis with effort and high loads. At the same time as the ski, and the caterpillar due to distortion shifts and turns the snow and earth.

In the proposed propulsion is a smooth change of the profile of the caterpillar blade, taking the form of the circle, which is produced by the rotation of the vehicle.

This truck is made symmetrically tapering from the Central portion to the ends of interconnected continuous elastic element fixed in the Central part of the tracks with the possibility of vertical and horizontal bending in any of your section, located in the gap between the tracks, combs or pins made in the Central part of the caterpillar blade along its longitudinal axis, and the turning mechanism includes a stabilizer caterpillar blade, and a vertical hinge, a fixed bearing which is fixed on the base frame and movable connected with the rotary section of the road wheels, moreover, the vertical axis of the hinge separated from the vertical plane passing through the horizontal axis of the track roller rotatable section, a distance equal to 0.3-0.8 of the distance between the horizontal axes of adjacent tracks caterpillar canvas.

Let us analyze in more detail the method of forming the essential features of this invention.

What you need to rotate the caterpillar canvas (part of it on the ground) in the horizontal plane?

1. To create a spatial gaps between the tracks, i.e. don't connect them directly horizontal hinges, as in the known vehicles with two tracks. However, depending on the angle of rotation, the tracks can shrink or not to shrink to the ends (this only affects the minimum turning radius of the vehicle).

2. Connecting tracks between a continuous inextensible elastic element, for example a steel cable that runs along the caterpillar canvas, precisely in its center. It will enable when you rotate to position the longitudinal axis of the blade on the circumference, which is the turning of the vehicle. The elastic element must be neresheim to the centerline of the blade to keep turning the set distance between the tracks.

3. "Fingers" of the track rollers and the "horn" of the tracks to lock the track rollers for crawler canvas the South be placed as close as possible to the center of each truck (ideally above the elastic element). This will ensure the coincidence of the distance between the fingers at the circumference of the rink with the distance between the coils of the canvas, despite the location of the blade around the circumference of the rotation.

4. To properly distribute the rotating and non-part area of the caterpillar fabric. Otherwise the vehicle or even turn will not, or will require a large engine power and will create a significant disruption of the surface on which it moves (as in the famous tracked vehicles).

Unfortunately, the desired complete absence of soil erosion by turning of tracked vehicles is utopia. It is possible to speak only about its reduction, and what is proposed by the mover. But it is very important to find the ratio of the part of the caterpillar fabric, which in turn keeps going in a straight line, and one that paves a new path caterpillar, putting her tracks by the selected radius. If the vertical axis of the swivel unit track Assembly is located in front of the vertical plane passing through the horizontal axis rotary rink, resting on the ground, the velocity vector of the vehicle due to the repulsion from the earth, you do not receive the lateral component. Accordingly, caterpillar canvas continues to move forward, despite the rotation before the his track roller and part of the caterpillar tracks in the side using a rotary device. Upon further action of the swivel mechanism Truckee blade slips off the control wheel.

If the vertical axis of the swivel unit is located behind the specified plane, and significantly, some part of the caterpillar canvas is the force of the swivel unit involved in the interaction with the earth and give lateral component. Turn any type of ground transportation is impossible without interaction with the earth (under the application of a pair of forces is offset from the rotary element and, by changing the position of the plane of focus in the earth, there is a lateral component of the velocity vector of the vehicle).

Thus, the feature of this conceptual view of tracked vehicles ("monogenic") is not that here, finally eliminated the interaction with the earth, as I think the authors specified in Annex 1 of the patent of Russia, and many other inventors, and change of the form of this interaction. Therefore, the front (swivel) part tracked paintings in the proposed propulsion plays the role of the little skis in the prototype (U.S. patent No. 3404745). It creates a lateral thrust in the ground and, thereby, the lateral component of the velocity vector.

For a direct proof of this provision, without which the creation of the mover of this type it is impossible at the level of patentable beings is the R signs, nor, especially, at the level of functional devices, the authors of this proposal have been built 2 existing models of vehicle with this mover. Testing of the first of them took place in August 2005, This model had a rotary mechanism in which the vertical axis of rotation could be moved forward and backward along the axis of the thruster. Tests have shown, at which distance the vertical axis of the hinge should defend from the vertical plane passing through the horizontal axis of the track roller rotatable section to any stable lateral component of the velocity vector thruster. With less distance model continued to move right, despite the operation of the rotation mechanism. The second model (the test took place in July 2006) already has no problem with turning. This is confirmed by the video, which was held during the tests of both models.

Figure 1 shows an external view (side) of the proposed propulsion. Figure 2 shows a caterpillar canvas (top view) in the process of turning of the vehicle with the proposed propulsion.

The thruster consists of a base frame 1, a broad-based caterpillar canvas 2 with 3 tracks. Fig 2 shows zavodny option caterpillar blade, and the role of coils play a depression 4 in the adjacent tracks, turned towards each other, together with the gaps 5 between the tracks. The canvas covers of the et lead 6 and guide 7 wheels as well as group support rollers 8 and the rotation mechanism 9.

Tracks 3 crawler paintings can be performed symmetrically tapering from the Central portion to the ends or may not be - it only affects the minimum radius of rotation of the propeller and are connected by a continuous elastic element 10, is fixed in the Central part of each of the tracks. The element 10 has the capability of vertical and horizontal bending in any of your section, located in the gap between the tracks. Combs or pins (figures 1 and 2 show that horn) made in the Central part of the caterpillar blade along its longitudinal axis. Group track roller 8 includes toggling 11 and 12 of the rotary section, and the turning mechanism 9 includes a stabilizer caterpillar blade 13. This stabilizer is designed to prevent saskachewan caterpillar canvas (SE) with the guide wheel 7 is located outside the SE, near the idler wheel, and installed with the possibility of its engagement with the outer surfaces of the Truckee SE. Possible variant implementations of the stabilizer 13 is the fulfillment of it in the form of one of the track rollers (8 or 12, as seen in figure 1).

The rotation mechanism 9 also includes a steering wheel 7, the rotary section 12 of the track rollers and the vertical hinge 14. Fixed support 15 of the hinge sacral is on the base frame 1, and mobile - connected with the rotary section 12 of the road wheels, and the vertical axis 16 of the hinge separated from the vertical plane 17, passing through the horizontal axis 18 track roller rotatable section, a distance D equal to 0.3-0.8 of the distance L between the horizontal axes of adjacent tracks caterpillar fabric. This is the horizontal distance L shown in figure 1 in the vertical plane for convenience of comparison with the distance D.

The proposed propulsion works as follows.

In the initial position the base frame 1 by means of groups of the track roller 8 and 12 rests on tracks 3 the lower part of the flotation caterpillar canvas 2. In the beginning of the movement begins to work leading engine (it can be different: the internal combustion engine, diesel engine, electric motor, etc.), it receives the rotation of the drive wheel 6. The teeth of the wheel 6 (see figure 1), which is in engagement with the coils of the caterpillar canvas 2, begin to move the tracks 3. The distance between the tracks remains unchanged due to the elastic element 10 (for example, a flexible steel rope), connecting the tracks. The mover is moved forward or backward, depending on the direction of rotation of the drive wheel 6.

If necessary, turn the vehicle left or right include turning mechanism 9, and guide wheels is 7, simultaneously with the turning section 12 road wheels and stabilizer caterpillar fabric 13, starts to move along the arc of a circle centered on the axis 16. Elastic element, portions of which are located in the grooves 19 of the teeth of the track roller 12 and the guide wheel 7, moved in space, transferring the tracks 3 caterpillar canvas 2. These grooves 19 track roller are clearly visible in figure 2 (a view of the rink from above). While the crawler tracks paintings occupy a new position (see figure 2) on the surface, on which the movement. The stabilizer 13 limits the instability of the horizontal position of the 3 tracks off of the idler 7 or the entrance to it.

Figure 3 shows the photo above second current model of vehicle proposed by the mover.
