Оценка устойчивости шарнирно-сочлененного колесного трактора и тракторного поезда в различных дорожных условиях

Abstract

The analytical expressions for the stability coefficient of the articulated wheel tractor and tractor train when turning, which allow to evaluate the resistance to skidding under different torque distribution between the axles were obtained. The analysis of stability coefficient dependences of the articulated tractor and tractor train from the coefficient of general torque distribution at turning in heavy road conditions showed that at inclusion of only one front-drive tractor axle the higher values of stability coefficient are provided, than at inclusion of only one rear-drive axle. At inclusion of both the front- and rear-drive axles the stability coefficient is higher than at inclusion of only one rear-drive axle, but it is less than at inclusion of one front-drive axle. The results obtained can be used at design of new and modernization of wheeled vehicles in operation.
