摘  要
汽车制动系统作为汽车底盘四大系统之一，重要性非常之大，其性能的好坏是直接关系到驾驶员的人身安全。有关资料证明，40%的道路交通事故与汽车的制动性能失效相关，其中10%的道路交通事故是由于紧急刹车时发生侧滑或偏移，使车辆丧失操作稳定性而造成的[1]。随着高速公路遍及全国四通八达、车流量增长迅速，人们迫切希望购买的汽车安全可靠，所以对汽车制动系统性能提出了更高的要求。可靠的制动系统对保证驾驶员及乘客的人身安全、保障交通道路通畅、维护社会秩序稳定具有重要的意义。
因此本文主要目的是对东风本田CR-V前制动系统进行设计计算，从制动系统的作用及设计要求出发，对多种制动器进行了对比，分析其各自的特点与不足之处，参考所搜集的关于东风本田CR-V的整车参数，进行计算分析，方案确定，以及校核验证，选用了浮钳盘式制动器作为东风本田CR-V的前制动器，制动盘采用通风盘式，并绘制出了前轮制动系统的三维模型和二维图。
本文的特色是综合运用所学专业理论和实践知识，掌握设计一般规律及正确的设计思路，解决汽车设计实际问题。通过制动系统设计，考虑实际制造工艺，使用性能，经济性能和安全问题，利用CAD，CATIA等软件进行绘图及优化，从而锻炼与提升个人的专业设计能力。

Abstract
As one of the four systems of vehicle chassis, the brake system is of great importance, and its performance is directly related to the safety of automobile driving. Nowadays, traffic accidents happen frequently in our life. Relevant data prove that 40 % road traffic accidents are related to the failure of braking performance, among which 10 % road traffic accidents are caused by sideslip or offset when emergency braking occurs, which leads to the loss of operation stability of vehicles[1]. With the rapid development of transportation and the increasing density of traffic, the demands for safety and reliability of automobile brake system are becoming higher and higher. The reliable braking system is of great significance to ensure the safety of drivers and passengers, to ensure the road unobstructed and to maintain the society orderly and stable.
Therefore, the main purpose of this paper is to design and calculate the front brake system of Dongfeng Honda CR-V. First of all, the function and design requirements of the braking system needs to be understood. Then the advantages and disadvantages of various style brakes are compared. Finally, according to the collected vehicle parameters, the scheme is calculated, analyzed and verified. It is concluded that the floating caliper disc brake is used in the front wheels of the car. The three-dimensional model and two-dimensional diagram of the front wheel braking system are drawn.
The feature of this article is to comprehensively apply the professional theories and practical knowledge, master the general design rules and correct design ideas, and solve the practical problems of automobile design. It is of great significance for cultivating ability that can analyze the structural performance of automobiles and assemblies, and rationally select the design scheme and parameters. Through the design of the brake system, it is necessary to consider the actual manufacturing process, using performance, economic performance and safety problems. Using CAD, CATIA and other software to draw and optimize also can train and enhance the professional design ability of individuals.
