Abstract

The proposed invention relates to compact tracked vehicles intended for towing people and goods in trailers or on sledges or flat-bottomed sleds over virgin snow and rough terrain. The towmobile comprises a rigid frame with supporting runners (sliders), which is fastened inside a propulsion device in the form of a rubber and fabric caterpillar track and to which is rigidly fastened a track tensioning mechanism mounted in the rear part of the towmobile, and a supporting device. On the frame there is mounted a front subframe for mounting a motor covered by a hood. A steering device in the form of a folding handlebar with instruments for controlling the motor is hingedly fastened to a rear subframe that is also provided with a baggage compartment and a towing device. This invention is intended to improve the movement of the towmobile when used in loose snow and to reduce the risk of breakdown resulting from the mechanical effects of the surrounding environment.

Description

TOWER

Technical field

The invention relates to small-sized vehicles on a caterpillar track, intended for transporting people and goods, 5 located in trailers, sleighs or drags, along snow virgin land and off-road.

State of the art

A towing tractor is known, comprising subframes for an engine with a control device and for a loading platform, an engine in the form of a caterpillar, inside which a frame is rigidly mounted, on which the track tension mechanism and supported runners (slides) are fixed; subframe for engine with control unit and subframe for cargo platform; wherein the caterpillar is made of two rubber fabric tapes interconnected by a steel profile,

15, the towing vehicle is controlled by means of a folding steering wheel pivotally mounted on a subframe for installing the engine, on the handles of which the engine control devices are mounted, and there is a tow hitch in the rear of the towing vehicle. (See the description of the utility model for the patent of the Russian Federation Ν ° 94947, IPC

20 B62M 27/00, published June 10, 2010).

The disadvantages of this model are the installation of the engine at the rear and the towing device at the front of the towing vehicle, which negatively affects the movement in loose snow: the front of the towing vehicle rises (pushes) upward, and the rear of the towing vehicle sinks in

25 snow, as a result of which the tug is buried in the snow and cannot move forward. In addition, when a towing vehicle is driven in, with a tensioning device installed in front of the structure, the tensioning devices of the towing track are damaged. The absence of a hood covering the engine is a significant drawback, since under cooling occurs at low temperatures and wind engine and possible mechanical damage to the engine when it encounters obstacles (e.g. bushes or tree branches).

Disclosure of invention

The objective of the invention is to develop a design, the operational characteristics of which are characterized by increased reliability and improved towing ability in deep loose snow.

The invention is aimed at solving the problem of ensuring the stability of movement, controllability and good adhesion of the caterpillar mover with snow.

This is achieved by the fact that the towbar contains a rigid frame with supported runners (slides), fixed inside the mover in the form of a rubber fabric caterpillar, to which the track tensioning mechanism mounted at the rear of the towbar is rigidly attached, and a support device. A front subframe is mounted on the frame for installing the engine, which is closed by a hood. A control device in the form of a folding steering wheel with engine control devices, as well as a boot and a tow hitch, are pivotally mounted on the rear subframe.

The location of the engine in the front part favorably affects the distribution of forces acting on the towing vehicle during movement, which increases its cross-country ability.

The location of the tensioner at the rear of the towbar protects the tensioners from oncoming impacts against obstacles.

A hard hood will protect the engine from external factors.

Brief Description of the Drawings

Figure 1 shows a General view of the tow.

Figure 2 - shows the direction of the forces on the tow.

An embodiment of the invention. The basis of the towing vehicle’s towing structure is a rigid frame 1 with supported runners (slides) 2, mounted inside the mover in the form of a rubber-fabric track 3, to which the track tensioning mechanism 4 is fixed, mounted

5 in the rear of the towing vehicle to prevent damage, and a support device 5. A front subframe 6 is mounted on the frame for mounting the engine 7, which is closed by the hood 8 to protect against mechanical damage, snow and dirt, as well as from freezing in cold or in the presence of strong the wind. On the rear subframe 9, a control device in the form of a folding steering wheel 10 with engine control devices, as well as a trunk 1 1 and a tow hitch 12, for which the towed load and driver's sleigh are attached, are pivotally fixed.

Improvement of patency is achieved by locating the engine 7 (in FIG. 1) in front of the towing vehicle, which structurally does not allow

15 to rise up the front of the towbar when driving in loose snow (all rear-wheel drive models suffer from this drawback), while the weight of the engine acting on the front of the towbar from top to bottom is F ₂ (figure 2) and the drag force transported behind the towing sleigh is Fi ( figure 2) hold the tow when moving

20 on deep loose snow in a horizontal position, which significantly improves the handling and patency of the towing vehicle. F _BblT - the power of the snow cover, trying to push the towbar up, placing it vertically (figure 2). The action shown in figure 2 forces with the location of the engine 7 in front of the tow

25 is balanced, which prevents the pushing and excessive lifting of the front of the towing truck upwards, positively affects the stability of the towing, improving its cross-country ability. Installing the engine in front of the towing vehicle favorably affects the distribution of forces acting on the towing vehicle while driving on dry snow. The location of the tension mechanism 4 of the caterpillar 3 in the rear of the towing vehicle (Figs. 1 and 2) protects the mechanism from oncoming blows against snow, ice and other obstacles, which virtually eliminates their curvature and breakage.

The presence of a hard hood 8 will protect the engine 7 from shock and external factors. It protects the engine from the effects of negative temperatures, stabilizing the temperature inside the towing body, thereby creating favorable conditions and optimal temperature conditions for the operation of the towing engine, which has a beneficial effect on the operation of the engine, extending the period of its trouble-free operation.

The towing machine works as follows. A towed object, for example, a drag, light sled, with the help of a towing device 12 is connected to the tow. The engine 7 is turned on, which drives the tracks 3 through the transmission and the towbar moves forward. The driver is in the sleigh seat. The direction of movement of the towing vehicle is regulated by the engine control devices made on the handle of the steering wheel 10. The direction and tension of the track are adjusted by means of the tension mechanism 4 of the track 3.

The towing vehicle is capable of carrying cargo up to 70 kg and transporting the cargo in a sleigh or drags up to 500 kg, breaking the snow powder of loose snow up to 70 cm deep. The towing vehicle can be used in various fields of activity where it is necessary to move goods and people in snowy conditions. , including:

- Transportation of fishing objects from hard-to-reach remote places (hunting, fishing, etc.);

- Transportation of goods for household needs in rural areas (firewood, water, food, etc.); - Support for the activities of sports ski and tourist recreation centers, resorts;

- Provision of services in the field of leisure and outdoor activities: rental, runs, etc .;

- Development of technical sports, technical clubs, including involving children and youth;

Support for the activities of exploration and scientific expeditions;

- Economic support of various facilities, industrial movement of small loads;

- Delivery of people and goods to objects in remote places: border posts, drilling stations, hydrometeorological stations, farms, forest rangers, forestry, fishing centers, etc .;

- Rescue operations in hard-to-reach remote places (MES);

Protection and patrolling of territories: borders, forest, livestock, hunting and fishing lands, internal territories of various objects (stadiums, bases, etc.);

- Maintenance of various communications: oil and gas pipelines, electric and television transmission lines, overpasses, railway lines, etc.
