Description

DEVICE FOR MOVING WHEELED VEHICLE EQUIPMENT ON SNOWY AND SLIPPED ROADS

The utility model relates to the field of automotive industry, in particular to ensuring the movement of wheeled automotive equipment in virgin snow, snowy roads and icy conditions, and can be used to move wheeled automotive equipment, KAMAZ, URAL, ZIL, UAZ, GAZ brands in the winter season, in difficult conditions.

It is known that the movement of wheeled vehicles on snowy virgin snow, snowy roads and in icy conditions is a complex process, which is accompanied by stuck vehicles, poor handling, skidding and skidding of a vehicle, and the driver must have the skills to drive a car in difficult conditions. When driving cars in the winter period of operation, the driver must perform a large amount of work, and when preparing the car for the march (flight) in low temperature conditions, additionally perform the work specified in the operating instructions. When making a march along snowy roads and in icy conditions, in order to improve the car’s passability in the event of wheel slipping, it is necessary to engage a reverse gear and put the car back, and then drive the car forward. When slipping the wheels again, reduce the air pressure in the tires with centralized inflation of tires or take measures to increase the adhesion of the wheels to the road (soil) using personnel or improvised means. Anti-skid chains are a means of improving cross-country ability and ensuring the safety of cars in winter. They are used to improve the grip of driving wheels when driving on slippery roads and snow virgin snow. (See Operation of automotive vehicles in difficult conditions. Manual. USSR Ministry of Defense, Main Automobile Directorate. Moscow: Military Publishing House, p. 1.5. P. 18-20; 114-115.1984). Anti-skid band chains are designed for single and double wheels. Also, snow chains can be reinforced by welding wire rods.

The drawback of the design of the tape chains is that the snow chains are used only for the period of overcoming difficult areas, and then require removal from the car. Snow chains have a small area of contact with snow and allow the vehicle to sink into the snow, as a result of which they cannot ensure the passage of equipment on roads with a significant snow layer, as well as the movement of equipment on snow virgin snow outside the roads.

The objective of the utility model is to create a structurally simple and technologically reliable device that provides the movement of wheeled vehicles, transportation of personnel and cargo delivery, regardless of the level of the snow layer and the condition of winter roads.

The technical result of using the utility model is the provision of the movement of wheeled automotive vehicles, the timely delivery of personnel, the transportation of goods in difficult climatic conditions, the increased patency of wheeled automotive vehicles.

The technical result is achieved by the use of a device for moving wheeled vehicles on snowy and slippery roads, which will provide cross-country ability, facilitate use, and improve the handling of wheeled vehicles in difficult climatic conditions.
