SMALL-KNOWN MECHANISM OF IV-GO TURN FOR TRACK MACHINES. ANALYSIS OF PROPERTIES OF MECHANISM AND KINEMATICS OF TURNING THE MACHINE
Abstract
The grading of the turning mechanisms (MP) of caterpillar machines (GMs) by their type, which influences the kinematics of the rotation of the GM, specifies the features of MP and their basic properties. Particular attention is paid to theoretical studies of the kinematic properties of the little-known IV type IV MP and to the analysis of its influence on the kinematics of the rotation of the GM. Comparative calculated data on MP of various types are given, in particular, the influence of the MP type on the speed properties of fast track crawler machines (BSM), which determine the possibility of their application in the structures of similar machines, is estimated. A mathematical dependence of the angular velocity of the rotation of the bogie is obtained depending on the ground conditions and the design curvature of the rotation. Based on the analysis of the properties of the GM with the considered MP of the IV type, conclusions are drawn about its main operational capabilities from the point of view of application in high-speed crawler machines (BSM) and tractors. The main shortcomings of PGM with MP of the IV type, which limit the use of the latter in the designs of modern GM, are identified.
