RU2329156C2 - Quick-detachable caterpillar vehicle attachment - Google Patents

Abstract

FIELD: transportation.

SUBSTANCE: invention relates to high cross-country capacity vehicles, in particular, to oversnow and overmarsh vehicles. The caterpillar attachment consists of a frame accommodating two rows of track rollers, guide wheels and a track tensioner. The vehicle is placed with its wheels on the tracks so that the wheels are arranged approximately above the track rollers. The caterpillar attachment frame is attached to the vehicle frame by two unparallel pivoted tie-rods. The vehicle braking system allows a separate braking of the LH and RH wheels, or, at least, of one LH and one RH wheel. As a result, the vehicle can run over hard terrain, in deep snow or over a soft ground. Note that the said attachment can be used with whatever type of vehicles.

EFFECT: simple design, ease of manufacture.

Description

The invention relates to vehicles, to off-road vehicles, namely to snow and swamp vehicles.

Known tracked transport and traction machines operating in difficult terrain [K. Frolov (previous) and other engineering. Encyclopedia. / Platonov V.F. (Ed.) et al. "Wheeled and tracked vehicles." T.IV - 15. M.: Mashinostroenie, 1997. p. 497 ..., 548 ...], high-speed tractors, snow and swamp conveyors, the chassis of which has a caterpillar mover. The caterpillar mover includes caterpillars, drive wheels, support and support rollers, steering wheels with a track tensioning mechanism. A common drawback of all known caterpillar transport and traction machines is that they belong to special equipment, have a low level of comfort and cannot be used for everyday driving around the city and highways.

The design of quick-detachable tracked attachments to the car is not known.

The objective of the invention is the creation of a simple, technologically advanced tracked attachment design that can be transported by road on a trailer, which can quickly install and secure the vehicle in the field, and also quickly remove the vehicle, allowing the vehicle to travel in difficult terrain in deep snow and on soft ground.

The solution to this problem is achieved by the fact that the crawler attachment consists of a frame with support rollers located on it in two rows, guide wheels, tracks and track tension mechanisms. The car is mounted with wheels on the tracks of the console so that the wheels are located approximately above the track rollers. The crawler attachment frame is connected to the car frame by two non-parallel articulated rods. In this case, the brake system of the car must provide the possibility of separate braking by the left and right wheels or at least one left and one right wheel.

The invention is illustrated by drawings, in which Fig. 1 shows a side view of a quick-detachable crawler attachment with a car, Fig. 2 shows a view A of Fig. 1, Fig. 3 shows an enlarged extension element B of Fig. 1, Fig. 4 shows an enlarged remote element In figure 1, figure 5 shows a section GG of figure 3, figure 6 shows a section EE of figure 4, figure 7 shows an enlarged extension element 3 of figure 6, figure 8 shows enlarged extension element D of FIG. 4, FIG. 9 shows an enlarged extension element G of FIG. 5, FIG. 10 shows an enlarged extension element A of FIG. 9, FIG. 11 shows chenny external AND gate 7.

The caterpillar attachment consists of a frame 1, on which the support rollers 2 and the guide wheels 3 are located in two rows. The guide wheels and the support rollers are of the same design, they are pivotally mounted with the help of bearings 4 on the axles 5, which are attached to the frame by bolts 6 with washers 7 1 (see FIG. 6, FIG. 7 and FIG. 11). The bolts 6 for fastening the axles 5 of the rear track rollers are screwed into the threaded holes of the sliders 8 of the track tensioning mechanisms, which protrude into the grooves K of the frame 1 with their protrusions, the threaded shanks of the sliders 8 pass into the holes of the supports 9 mounted on the frame 1, and two nuts are installed on them 10 (see Fig. 8). Caterpillars are dressed on each row of track rollers and guide wheels 11. Wide reinforced belt tracks can be used. Two brackets 12 are mounted on the console frame 1, and two brackets are mounted on the car frame 13. The car is mounted on wheels on tracks 11 so that the wheels are approximately in the center of the tracks and above the track rollers 2. The brackets 12 are connected to the brackets 13 by articulated rods with spherical joints which consist of threaded rods 14 and 15 with spherical heads, shrink couplings 16, locknuts 17 and 18, spherical hinge bodies 19, spherical liners 20 and 21, covers 22, screws 23 for securing the cover, adjusting screws Adok 24 and sealing covers 25. The cases of the spherical hinge 19 are attached to the brackets 12 and 13 with bolts 26, nuts 27 and washers 28 (see Fig. 3, Fig. 5, Fig. 9 and Fig. 10). Instead of spherical joints, universal joints can be used.

Quick-detachable crawler attachment works as follows.

The crawler attachment can be transported by road on a trailer. The car can drive on its own on the tracked console on inclined beams installed behind the console. The car is mounted so that the wheels are approximately in the center of the tracks and above the track rollers. After installing the car, the attachment frame 1 is connected to the car frame by two non-parallel articulated rods. In this case, the bodies of the spherical hinges 19 are attached to the brackets 12 mounted on the frame 1, and the brackets 13 mounted on the car frame, bolts 26, nuts 27 and washers 28. If necessary, adjust the length of the rods by rotating the shrink couplings 16 relative to the rods 14 and 15, after which the shrink disk is locked with locknuts 17 and 18. Also, by changing the length of the articulated rods, a more accurate exhibition of the car relative to the frame 1 of the crawler attachment can be made. To tension the tracks, loosen the bolts 6 of the axle 5 of the rear track rollers, tighten the track by moving the sliders 8 by turning the nuts 10, tighten the bolts 6 and lock the nuts 10 with the second nuts 10. If necessary, you can rearrange the 5 axis with bolts 6 to other threaded holes on the sliders 8. The articulated rods fix the car frame relative to the frame 1 of the crawler attachment, ensuring that the car wheels are pressed against the tracks and track rollers under the influence of the car weight and the normal operation of the car suspension. Driving wheels of the car during their rotation rewind the tracks in the direction opposite to their own rotation, non-driving wheels rotation is transmitted from the tracks. So, to move the car along with the crawler attachment forward, you need to include reverse gear on the car, and forward movement to reverse. To make a turn, it is necessary to brake the left or right wheels depending on the direction of rotation, for which the brake system of the car must provide the possibility of separate braking by the left and right wheels or at least one left and one right wheel.

In order to remove the vehicle from the tracked attachment, it is necessary to disconnect the articulated rods from the vehicle, after which the vehicle can move off the tracked attachment under its own power along the inclined beams installed at the rear of the console.
