商用车制动系统故障分析和诊断研究

Research on analysis and diagnosis the fault of commercial vehicle brake system

近几年,我国在公路建设和运输事业和汽车市场取得了飞速发展,而我国又是一个多山国家,很多依山而建的公路坡度大且坡长很长,在这种状况恶劣的道路下坡制动时,必须保证汽车在下坡行驶至坡道结束时其行车制动系还具有足够的制动性能。而商用车由于装载质量大,持续制动时温升快,容易现交通事故。因此有必要针对商用车制动系统故障进行分析和研究。文章通过对制动系统的历史,发展和现状的总体概述,通过对制动系统的结构和原理以及制动过程的分析和研究。分析造成商用车制动系统故障的常见问题,并作出针对这些问题的处理办案,从而总结商用车制动系统常见故障的一些原因和处理办法,和制动系统保养的建议。

In recent years, our country's highway construction and transportation industry and automotive markets have made rapid progress. And our country is a mountainous country, whose hillside road slope steep and the slope length is long. In this situation of poor road downhill braking, we must ensure that vehicles traveling in the downhill at the end of the road to the ramp brake system also has sufficient braking performance. As the truck have large kinetic energy, temperature rises fast in continuous braking, accident prone. Therefore it's necessary to analyze and make a research on fault braking system for commercial vehicle. This paper is based on the general overview of the braking system for its history, development and current status, through the discussion and analyzing of the structure and the braking process, analyzing the common problems caused by faulty braking system for commercial vehicle and making a case for these problems, then making a summary of the causes and treatment measures of common fault for commercial vehicle. Finally, there are some maintenance recommendations for braking system.
