Abstract

In this paper, the development status, influencing factors and existing problems of 13T concrete mixing truck cooling system are briefly analyzed. The design concept and research methods of cooling system of 13T concrete mixing truck at home and abroad are introduced, such as intelligent electronic control cooling system, precise cooling idea, shunt cooling, air side flow and engine heat management research, etc. The aim of realizing high efficiency and low consumption in the cooling system of modern 13T concrete mixing truck is prospected. It is pointed out that the effective integration of accurate cooling and shunt cooling with electrically controlled cooling components is an effective means. However, the research on the heat management of the whole vehicle is bound to become a comprehensive proposal. Main methods of high cooling system performance. This paper analyzes the working principle of the cooling system of the 13T concrete mixing conveyer, and completes the improvement design of the main structure of the cooling system of the 13T concrete agitator by using the specialized knowledge and courses learned. The motion analysis and parameter calculation of the cooling system of 13T concrete mixing truck are completed.

Key words: concrete mixing truck, cooling system, intelligent control, operation analysis
