Description
The development of agricultural production inevitably entails an increasing volume of traffic and a turnover of goods. Therefore, the issues of increasing transport efficiency, reducing the price of transportations and improving productivity acquire great importance. In most cases, supersize dump trucks used for the transport of agricultural production have much more than 6 tons axle load. Thus, these cars need to have roads with improved surface to each field, which undoubtedly is a significant drawback. Because of the extra movements of harvester dump trucks on the turning strip at the end of the field, it increases expenses of damage and loss of crops and the arrival of heavy machinery in the field leading to soil compaction, that in the end affects the future crop. Transportation of agricultural commodities is most effective when the car arrives directly to the harvester machinery. Such vehicles must have sufficient abilities and capacity of the body comparable with the volume of a combine hopper and has no significant impact on soil sealing. With this method, harvesters do not make extra movements and are not idle. Basic requirements for vehicles used in the harvesting potatoes, are in a more productive use due to increasing the capacity and reducing downtime when loading or unloading and minimizing the level of damage to other tubers. For the transportation of agricultural products there is a different transport technology, which either do not fully meets the requirements of transportation of highly fragile product, or has a significant cost. Therefore, we require a specially equipped vehicle bodies, with a competitive ability in the range acceptable to the Russian Federation. As one of the innovative developments, this article proposes a tipper body of the vehicle for transportation of highly fragile agricultural products. The proposed design solution for the tipper ensures a uniform unloading of transported products from the vehicle body and prevents arching issues

PROBLEMS AND PROSPECTS OF TRANSPORT TECHNOLOGY FOR VILLAGES
DescriptionModern condition agricultural transport (a significant part of it about 70%) is characterized by a strong deterioration of the rolling stock, the unsatisfactory state of the production base. More than 30% of vehicles operated outside the normative service life, the rest approaching to that state. In general, the provision of agrarian and industrial complex with agricultural vehicles is way below agrotechnical requirements. In the long term, farm machine engineering should focus on indicators of the technical level achieved by best samples of foreign agricultural machinery. Priority development is likely to receive the development of innovative technologies that provide a significant increase in productivity, efficiency and resource conservation in agriculture. To address the shortcomings of transport services agrarian and industrial complex we should improve transport technology with the use of transport logistics, expand and update the existing vehicle fleet, but due to the low solvency of agricultural companies and high prices for of automotive engineering, the problem of providing agricultural vehicles becomes most acute. Thus, the creation of new science-based solutions in technology and engineering for transportation farm produce in terms of Russia's AIC is the actual scientific and technical task that contributes significantly to the development of the country, as well as enhances the enjoyment of breakeven, competitive manufacturing

CHALLENGES AND TECHNICAL SOLUTIONS OF USING HIGH-PERFORMANCE TRANSPORT OF AGRICULTURAL MACHINERY
DescriptionMaterial and technical resources form a large part of the costs in agricultural production and determine the level of intensity of agriculture, productivity and competitiveness of the industry. The most important role in agricultural production is played by transport operation, from productivity and quality of which directly depends the volume and the grade of final products. More preferable is tractor transport, particularly for on-farm transport, taking into account the impact of navigation systems on the ground. Continuous growth in the saturation of tractors carried out around the world, improves the performance of tractor transport aggregate by increasing their capacity and speed, either on the road or in the field. However, if you increase the saturation of tractors, it encounters problems related to the deterioration of the controllability of the tractor and transport unit. The reduced controllability leads to an increase of damage to transported agricultural products owing to increased oscillatory processes in the system of "road – trailer – tractor – operator" when driving on-farm trails, deteriorating the smoothness and braking properties. Especially sharp these questions relate to transportation of easy-to-damage agricultural products at farm transportation. The feature of data traffic lies in the sharp drop in grade products (products receive numerous mechanical damages, deteriorating its quality, and lose marketability and accordingly reduced its cost). Influence on fruit and vegetable products of unfavorable factors can lead not only to a dramatic loss of quality at the time of transportation, but also reduce the resistance during further storage. To solve the problems emerging when increasing the saturation of tractors, we have proposed devices, allowing reducing negative impact on the production of elevated oscillatory processes, to increase the permeability and straightness of movement of tractor-transport unit

Description
Based on the previous investigations we have underlined the need to increase fruit and vegetables preservation quality while transporting them from the producer to the consumer at the expense of improving the road transport operation for its intended purpose. We have made a conclusion about the need to develop strategies for maintenance and repair as for the actual technical state at the expense of developing the diagnosis system based on the development of a math model of changing the technical state of the diagnosis object, developing a method of rational set of objects to be diagnosed and determining the technical state optimal control frequency. We have confirmed that the above mentioned is possible when considering the system of technical operation of road transport as an organization-production system and applying the engineering-cybernetic approach to improve this system. We have considered the basic requirements for the efficiency indexes when investigating and improving the operation system that will allow achieving the aim we have had and can be described mathematically. We have made a conclusion about the urgency of the issue we studied and the possibility to develop the efficient operation system of road transport based on the provided criteria

APPLIANCES, TECHNOLOGIES AND EQUIPMENT FOR HAULING OF FRUIT OUT THE GARDEN
DescriptionAn integral part of technological process for the cultivation of agricultural crop is the transportation issues. For their execution, we require significant energy and labor costs. The statistics show that the proportion of expenses for transportation of goods in agriculture reaches 25-40% of the total costs for ready-to-sale production, when the proportion of farm tractor transportations reaches 60% of the total. Thus, there are considerable losses of production, reaching in separate cases up to 50%. They are especially great in the harvesting and post-harvest cycles of crop production which is connected with crop damage during transportation. Large losses of fruit and vegetable products when transporting might be connected with their mechanical damage level during loading, unloading and transportation. This causes the urgency of the problem of preservation when transporting fruit and vegetables. One of the prior national issues is "... the development of directions to improve road transport maintenance with the aim of improving the quality of the transport process, which includes increasing commercial speed of freight flows by 2-3 times, increase productivity and profitability of road transport systems by 2-3 times, reducing the environmental load on nature by 20% ... " and others mentioned in the "Transport Strategy of Russia until 2020"

ANALYSIS OF METHODS AND MEANS OF DIAGNOSTICS OF BRAKE SYSTEMS OF VEHICLES
DescriptionThe article presents native and foreign bench-top and board methods to test the automobile break systems. One can find information about some native trailer-break stands. We have analyzed their advantages and drawbacks such as low information capacity, high diagnostics processing time, low quality of regulation and maintenance operations due to big influence of the operator’s experience, his knowledge and individual characteristics, and great instability of manual test modes on the results of the investigations. To remove these shortcomings they have had some experiments at MADI in order to develop the module to the brake qualities stand. When using it one can have automatic diagnoses and flow chart is presented in the article. Due to the existing vehicles’ state inspection mode and diagnostic means in our country there appeared new stands for brakes control. One can attribute to these devices a range of brake qualities stands developed and produced at Novgorod plant GARO. These are STS-3, STS-10 and STO series stands for cars, trucks, buses and micro-buses. The article also presents some foreign stands used in Russia such as universal brake stands STM by META firm, the break stand IW7 Eurosystem by MAHARUSSIA firm. We have presented in the article the results of the analysis of simple and complicated board means of diagnosis as “Eftor-2”, “Effect”

Description
An integral part of technological process for the cultivation of agricultural crop is the transportation. It requires significant energy and labor costs. The statistics show that the proportion of expenses for transportation of goods in agriculture reaches 25-40% of the total costs for the production made, when the proportion of farm tractor transportations reaches 60% of the total. Thus there are considerable losses of production, reaching in separate cases up to 50%. They are especially high in the harvesting and post-harvest cycles of crop production which is connected with crop damage during transportation. The quality of fruits and vegetables during the harvest depends on the technology of its collection and transportation. Due to the rapid deterioration of most agricultural products, agricultural producers have the task in careful transportation of the fruit. A huge role in the preservation of the product is its harvesting and packing into containers. In Russia we use wooden boxes, and foreign farmers use containers, whereby they have higher productivity and preservation of fruits. The type of vehicle, the time of a day and the air temperature also have a large impact on crop damage. In Soviet times, various technologies have been developed for harvesting and transportation of the harvest to consumers using various types of forklifts, harvesters and vehicles. In our time, it requires the development of new technologies for harvesting and transportation of agricultural products to achieve a higher level of automation and high profitability of agricultural production
