LEVEL OF INFORMATION SIGNAL FROM LINEAR DISPLACEMENT TRANSDUCER FOR PISTON OF GEARBOX HYDRO-PRESSING CLUTCH AS COEFFICIENT OF WEAR AND VALUE OF RESIDUAL OPERATING TIME

Abstract

In the context of market relations one of the main challenges facing the industry of the Republic of Belarus is to raise a technical level, reliability and competitiveness of wheeled and tracked vehicles. On-board diagnostics improves quality of wheeled and tracked vehicles, increases reliability of their aggregates and units. Scheduled preventive maintenance and repair system as well as sporadic control and diagnostic works can not provide the required level of technical state of wheeled and tracked vehicles because the procedures do not take into account individual peculiarities of each machine, its operational conditions and previously conducted repair measures. One of the ways to solve the problem is to develop onboard diagnostic methods for technical state of powertrain wheeled and tracked vehicles that permit to carry out maintenance at actual requirements. Following this approach it will be possible, firstly, to exclude failed machine operation and, secondly, unjustified material and labour costs in case of untimely maintenance.

On-board diagnostics of power units and, in particular, gearbox hydro-pressing clutches must ensure high rate of road traffic safety. Usage of an information signal from linear displacement transducer for a piston of gearbox hydro-pressing clutch will make it possible timely to determine residual operation time of friction disks at any operational period of “Belarus” tractor and also forecast time when it is necessary to substitute them.
