Hybrid transmission of a multi-axle wheeled vehicle

Abstract

The features of the formation of traction and dynamic characteristics of multi-axle wheeled transport vehicles are analyzed. The prospects for the use of electromechanical (hybrid) transmissions of various types as part of the chassis of transport and transport-traction wheeled multi-axle vehicles are analyzed. The principles for constructing kinematic diagrams of hybrid transmissions are proposed, allowing for complete control over changes in the traction forces of individual drive wheels when using the principle of parallel and parallel-series hybrids. Examples of kinematic diagrams of inter-axle and inter-wheel controlled power distribution mechanisms are considered, as well as principles for determining and implementing the values of their external parameters. Attention is paid to the issues of control technology for such mechanisms based on the principle of controlled slipping of the disc friction control element, as well as the prospect of localizing the production of components and assemblies of such transmissions at enterprises of the Russian Federation.
