TRANSPORT AND TECHNOLOGICAL MODULE WITH ELECTRIC WHEEL DRIVE

Abstract

Agriculture of the Russian Federation suffers huge losses due to the lack of the necessary equipment to work on soils with low load-bearing capacity. As a result, harvesting of winter crops takes more than 40 days, and crop losses amount to 42 percent. When applying fertilizers, about 40 percent of the soil surface is compacted by the wheels of agricultural machinery. Compaction of the soil leads to the appearance of large and dense blocks of earth during plowing. Tractors of traction classes 1,4-5 are used as part of the tractor fleet of peasant farms. Such a nomenclature of tractor types leads to additional costs associated with low annual loading of tractors, over-compaction of soils, tractors of high traction classes. (Research purpose) The research purpose is justifying the use of a transport and technological module with an electric wheel drive. (Materials and methods) Gave a schematic diagram of a modular power-technological means and a kinematic scheme of the wheel drive of a transport and technological module. (Results and discussion) We have developed a transport and technological module with an electric drive of the driving wheels from the generator, which in turn rotates due to the tractor power take-off shaft connected by a cardan transmission. It was determined that the electronic control unit and wheel speed sensors are responsible for the necessary kinematic correspondence between the driving wheels of the tractor and the transport and technological module. It was found that this eliminates the need for a synchronous power take-off shaft on the tractor and, as a result, makes the technological module universal. (Conclusions) It was shown that the use of a transport and technological module with an electric wheel drive serves as an effective way to solve the problem of ballasting and makes it possible to improve the technological properties of a second-generation tractor. It was stated that the use of a transport and technological module with an electric wheel drive will allow the tractor to be used to perform transport work requiring a large traction force on soils with low load-bearing capacity, such as the transportation of forests, manure in the spring and autumn thaw and others.
