Mechanisms of power distribution: principles of kinematic and force analysis

Abstract

The article considers the features of performing kinematic and power analysis of a controlled power mechanism for the transmission of wheeled transport and transport-technological machines. Such mechanisms are currently used mainly on cars in order to improve handling, stability, traction and dynamic properties in severe road conditions. Such mechanisms are not produced in Russia, but theoretical studies are currently being conducted, the results of which will allow determining the main parameters of the mechanism and synthesizing its kinematic scheme. The proposed approaches are based on the methods used in the kinematic and force analysis of planetary gears, but it is taken into account that the mechanism of power distribution during operation has two degrees of freedom. It is indicated that there is a structural and functional similarity between the power distribution mechanism of the car and the turning mechanism of the tracked vehicle. A method is proposed for calculating the gear ratio of the power distribution mechanism according to the condition of matching the minimum possible turning radius provided by the steering trapezoid kinematics and the calculated turning radius.

Computational approach to estimation the transverse Stability of multi-section chassis of extreme cross-country vehicles

“…The principles of building advanced transmissions for two-link machines (see, for example, publications [13,14,15,16] are supposed to be extended to a multi-section chassis. It is expedient to carry out the control of the turn with a significant mass of the machine in a combined way -due to the mutual turn of the sections and the change in the traction forces along the sides [17,18,19,20,21,22,23]. To analyze the operation of the transmission, models similar to those described in the article [24] can be used.…”
