摘要：At vehicle movement, there are two factors that specify conflicting requirements for transfer box drive and axle drive. Let’s describe them: each wheel rotating at different speeds and reduced adherence of one or more wheels. The road conditions: the decrease in friction and kinematic disparity, acting often at the same time, present conflicting requirements to drive of the driving wheels. These factors tend to be of time-varying nature. The nature of the studied processes is transient; it will be influenced by the inertia, stiffness and damping properties of the vehicle power train parts. The efficiency reflecting losses on wheel slip is proposed as a uniform selection criterion of an interaxial drive. Based on comparison of dependence of this parameter on road conditions, higher efficiency of differential with limited gear ratio compared to simple differential and blocked drive is shown. The chosen approach on the basis of quantitative indices proves the efficiency of differential with the limited transfer ratio in comparison with other main types of the drive, such as differential and blocked.
