Practical implementation of research on the introduction of on-board meters-indicators for monitoring the technical condition of tractors

Abstract

Reducing the excess costs of the consumer due to timely maintenance and increasing the efficiency of detecting deviations in technical condition to improve operational reliability is an important task in improving the efficiency of using energy-saturated tractors of domestic production. In order to promptly provide initial information on the degree of use and the current state of resource-determining parts and assemblies, as well as to increase the controllability and adaptability to diagnosis, indicator counters integrated into the design of tractors are used. Diagnostics and information collection allows us to prevent failures and minimize costs under the conditions of branded service, as well as to monitor the current state of equipment that is under warranty or under lease. In the production of energy-saturated tractors most of the main components and aggregates in the JSC "St. Petersburg Tractor Plant" transmissions are made independently, with the exception of bearings and friction discs. Therefore, in order to increase the operational reliability of the tractor as a whole the proposals for the development of indicator counters were carried out primarily to increase the controllability and adaptability to the diagnosis of power transmissions, as the most relevant for minimizing the costs of the manufacturer, leasing company, and end user. Producing plants, research teams and individual laboratories are engaged in research to solve problems of increasing the resource of agricultural machines and tractors. However, the main indicators of the reliability of agricultural machinery increase with low dynamics, and the cost of maintaining machines increases sharply in the post-warranty period of operation [1-3].
