Abstract
The intention of the paper is to investigate the agricultural tractors transmission service load during common operation and to correlate it with installed engine performance. This enables: (i) accurate prediction of relevant input for design of a new transmission, (ii) better prediction of transmission life time and reliability and (iii) conducting of laboratory tests which will have higher correlation with real service cycle. The last one aspect is especially highlighted in the text.
The paper presents results from a lot of typical tests done on agricultural tractors during real service in particular market. The specific application for which the tractor is used in that market has significant influence to the observed service load what is highlighted in the paper. All data relevant for accurate defining of a transmission service load were acquired and analyzed. Special attention was paid to the proper data evaluation, which has enabled recognition of all phenomena of interest. Establishing correlation between service load and engine performance, one can extrapolate obtained results to apply for other tractor transmissions.
