Abstract

A towing vehicle containing a mover in the form of a rubber-fabric caterpillar, inside of which a frame with a fixed tension mechanism and supporting runners (slides) is rigidly mounted, front and rear subframes on which the engine and a pivotally mounted control device are installed in the form of a folding steering wheel with engine control devices, as well as trunk and tow hitch, characterized in that the engine protected by the hood is mounted on the front subframe, and the track tension mechanism is located at the rear towing vehicle.

Description

The utility model relates to small-sized vehicles on a caterpillar track, designed to transport people and goods in towing devices, sleighs or drags, along virgin snow and off-road.

A towing tractor is known, comprising subframes for an engine with a control device and for a loading platform, a caterpillar propulsion device, inside of 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; in this case, the caterpillar is made of two rubber-fabric belts interconnected by a steel profile, the towing vehicle is controlled by a folding steering wheel pivotally mounted on a subframe for installing the engine, on the handles of which engine control devices are mounted, and there is a tow hitch at the rear of the towing towing vehicle. (See the description of the utility model for the patent of the Russian Federation No. 94947, IPC В62М 27/00, published on 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 the snow, as a result of which the towbar is buried in the snow and can't 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 at low temperatures and wind the engine overcools and mechanical damage to the engine is possible when it encounters obstacles (for example, bushes or tree branches).

The objective of the utility model is to develop a design whose operational performance is characterized by increased reliability and improved towing ability in deep loose snow.

The utility model 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.

The proposed utility model is illustrated by drawings, where:

figure 1 shows a General view of the tow;

figure 2 - indicates the direction of the forces on the tow.

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 fixedly mounted at the rear of the towbar to prevent damage, and the supporting device 5 A front subframe 6 is mounted on the frame for mounting the engine 7, which is closed by a hood 8 to protect against mechanical damage, snow and dirt, as well as from freezing in frost or in the presence of strong 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 11 and a tow hitch 12, for which a towed load and driver's sleigh are attached, are hinged.

Improvement of patency is achieved by locating the engine 7 (in Fig. 1) in the front of the towing vehicle, which structurally does not allow the front of the towing vehicle to rise upward 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 towing truck from top to bottom - F2 (figure 2) and the drag force of the sleigh transported behind the towing vehicle - F1 (figure 2) holds the towbar when moving on deep loose snow in a horizontal position, which significantly improves so handling and cross-tow. Fout is the strength of the snow cover trying to push the towbar up by placing it vertically (FIG. 2). The action of the forces shown in Fig. 2 when the engine 7 is located in the front of the towing vehicle is balanced, which prevents the pushing out and excessive lifting of the front part of the towing truck, which 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 loose 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, incl. with the involvement of children and youth;

- Ensuring 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.
