电子真空泵保险丝熔断分析改进研究

Analysis And Improvement Of Electronic Vacuum Pump Fuse

随着环保要求的越来越严格,国家和地方对新能源车的鼓励和支持推动了新能源车的购买需求,2021年销量更达到了136.7万辆,创了历史新高。电子真空泵作为纯电动车唯一的真空提供源,是制动系统中至关重要的部件,如产生失效故障,就无法提供真空助力,降低了制动安全性,同时非常容易乘客抱怨.本文对某车型制动系统的电子真空泵保险丝熔断的故障进行了全面分析,并通过改进彻底解决了该故障。为平台车型的开发提供了技术支持!

With the increasingly stringent requirements of environmental protection,the national and local encouragement and support for new energy vehicles promote the purchase demand of new energy vehicles.In 2021,the sales volume of new energy vehicles reached 1.367 million,a record high.As the only vacuum source of pure electric vehicle,the electronic vacuum pump is the most important component in the braking system.If it fails,it will not be able to provide vacuum assistance,which reduces the braking safety.At the same time,it is very easy for passengers to complain.This paper makes a comprehensive analysis of the fuse failure of the electronic vacuum pump in the braking system of a certain model,and thoroughly solves the failure through improvement to provide technical support for the development of platform models!
