有人能帮忙英文翻译摘要吗？跪求 Car is the most widely used in all kinds of traffic tools，the most suitable，the most convenient time for a transportation.In order to ensure that the car safety and make the power performance of vehicle，car must have a good brake and brake performance good，this is the starting point of our design.The reference model for CA7220 car.Braking system in line with the requirement of the vehicles as a car brake smooth，shorter braking distance，meet the safety of the car and occupant comfort，therefore selects the front coil after the drum type.In this way，the brake system and high brake efficiency and higher efficiency factor of stability.Then，the design process of the specific structure of the disc brake has carried on the detailed elaboration.Choose the power device using human hydraulic braking system.Hydraulic shunt system determines CA7220 finally for X line form.Transmission device of brake master cylinder adopted double circuit brake system.In the design and calculation part，first of 。
液压制动系统的主要组成部件有哪四种？ 制动系统主要由供能装置、控制装置、传动装置和制动器4部分组成
汽车刹车时是四个车轮一起刹车吗，为什么？汽车在进行刹车时，四个车轮是同时进行制动的，这里不存在先、后差异，而存在的只是前后制动力的分配差异；。
为什么大型车辆刹车一般用气刹，普通汽车用液压？
什么是单回路制动系统？ 单回路制动系统就是在汽车制动传动装置中采用单一的气压或液压回路的制动系统。或者说前、后桥制动回路是串联关系。单回路制动系统中只要有一处损坏，譬如液压制动系统中。
汽车制动系的组成 1）按功用分：行车制动系驻车制动系辅助制动系 1）按功用分：行车制动系驻车制动系辅助制动系 1）行车制动系—是由驾驶员用脚来操纵的，故又称脚制动系。。
