Abstract

The efficiency of the use of high-energy tractors in agriculture is largely determined by the level of preparation for field work, which in turn depends on the completeness of the repair and maintenance work. Various diagnostic tools are used for a non-selective assessment of the general technical condition of internal combustion engines: motor testers, crankcase gas flow meters, etc. Currently, there are no means to assess the technical condition of the gearbox without breaking the power flow. The development of digital diagnostic tools is required to reduce the risk of failures during field work. (Research purpose) The research purpose is studying the state of the issue and justifying the need to develop a coefficient for a non-selective assessment of the general technical condition of the hydraulic transmission control drive of high-energy tractors. (Materials and methods) Carried out an analysis of the complex of works on diagnosing and managing the reliability of agricultural machinery. It was found that it is necessary to control the time of the transient process in the hydraulic control system of the gearbox, as well as accelerations during gear shifting. We reviewed the previously manufactured control and diagnostic equipment. The KI-12383 and "Effect-02.01" devices were chosen as a prototype for the development of a digital indicator. (Results and discussion) We conducted a simulation, designed and tested a prototype and proved the possibility of developing a digital indicator that can be used as an integrated diagnostic tool to justify the need for repair and maintenance effects of the gearbox. (Conclusions) To monitor the general technical condition of the gearbox, a digital indicator is needed, which will allow, without making changes to the design (K-701, T-150K and their modern analogues), to obtain diagnostic data to substantiate repair and maintenance impacts in order to reduce the risks of failures of the III complexity group during field work.
