The Project Design of the Tracked Vehicle Hydraulic Mechanical Differential Steering

Based on the principle of hydraulic mechanical stepless transmission is tracked vehicle hydraulic mechanical differential steering system can effectively improve the vehicle's steering can win, is has good prospects for development of a tracked vehicle steering model. Papers on tracked vehicle and its present situation and trend of development of the steering system, analysis of the hydraulic mechanical differential steering system structure, working principle, the vehicle steering lung can and on the basis of the research and application status at home and abroad, puts forward the main content of the steering system research and to solve the problem. In the output shunt transmission and input shunt two basic hydraulic mechanical transmission based on the analysis of the features, according to the requirements of the tracked vehicle steering, identified a new type of hydraulic mechanical differential steering system transmission scheme, this scheme has the advantages of simple structure and increasing the torsional speed down, caterpillar vehicle is suitable for agricultural use.
