摘 要
我们将使用制动驱动机构的制动蹄把制动摩擦片压在内心的制动鼓,导致制动力,为鼓式制动器。需要保护停车场不能可靠地滑,需要使车轮或在最短的距离停下来,为了确保行车安全。
制动系统由4部分组成,提供设备、控制装置、传动装置和制动。制动系统的主要功能是驾驶汽车减慢甚至停止,使下坡的速度驾驶汽车保持稳定,一直悬浮在汽车保持不动。汽车的制动系统中起着重要的作用,如果失效将导致灾难。制动系统的主要部件就是制动器,在现代汽车仍然广泛使用的是具有较高制动效能的蹄—鼓式制动器。制动器的设计相关的设计和计算。在设计过程中,实际的产品为基础,根据我国目前制动的一般过程和发展新产品,并结合设计理论的要求,首先根据给定模型的车辆参数和技术要求确定制动器的结构形式、制动和选择的主要参数,然后计算制动器的最大制动力矩、同步附着系数、制动功率和制动力分配系数,制动器结构参数和摩擦系数,在此基础上主要制动部件的结构设计。最后,完成装配图和零件图的绘制。

Abstract
Drum brake, also known as block-type brake, drum brakes, now within the mainstream style sheets, and its brake shoes located inside the brake wheel, brake brake blocks out when open, the inside wheel friction brake, to achieve the purpose of the brakes.
In the vehicle braking system has a very important role, failure will result in disaster if serious consequences. The main parts of the braking system is the brake, in the modern car is still widely used in high performance brake shoe - brake drum. The design of the friction drum brakes were related to the design and calculation. In the design process, based on the actual product, according to our current brake factory general new product development process, and theoretical design requirements, the first model of the vehicle according to the given parameter and the technical requirements, determine the brake structure and, brake main parameters and their choice, and then calculate the maximum braking torque of brake, the synchronous adhesion coefficient and brake force and brake force distribution coefficient, the structural parameters of the brake and friction coefficient, deformation shoe, brake effectiveness factor, braking deceleration, wear characteristics, brake temperature, etc., and in this brake on the basis of the structural design of major components. Finally, assembly drawings and parts to complete mapping.
