INFLUENCE OF ROAD CONDITIONS ON RELIABILITY OF VEHICLE TRANSMISSION

In order to upgrade the vehicle transmission elements in terms of reducing their size and weight and simultaneous achieving required level of reliability the contemporary design of these elements is based on real stochastic nature of working and critical stresses as design basic values. Consequently, working and critical stresses are considered as random variables with distribution at appropriate intervals of dispersion where different values of working and critical stresses find different appearance probabilities. Therefore, reliability evaluation of the vehicle transmission elements is made on the base of probability where working stresses are lower than critical ones. In that respect, this paper deals with the influence of road conditions on reliability of the vehicle transmission elements highlighting of the driving shafts with different diameters.
