内容简介：

附 录附录ABraking system function is to make the car driving in accordance with the requirements of the pilot required even slow down park; They offend car has in various road conditions (including in the slope stability) in car; Make the downhill cars speed to be stable. For car up the role of brake is only in the car and role with the direction of the car driving direction opposite forces, and the size of these forces are random, do not control, so cars must be installed on a series of special equipment to achieve the function. Automobile brake system is to point to to ensure that the car in technology, improve the safe driving car average speed, etc., and the admiration installed in the car brake special brake institutions. In general automobile brake system including crane brake system and parking brake two sets of independent device. One crane brake device is a driver with feet to manipulate, and it said the foot brake. Parking brake device is a pilot with the hand, so it says of the manipulation of the hand brake. The function of the crane brake system is to make the car slow down or running in the shortest distance parking within. And parking brake function is to make had stopped the car on the road all keep still. But, sometimes, in an emergency, two braking device can be used at the same time and increase the effect of auto brake. Some special purpose of cars and often in the mountains cars, long and frequently brake will lead to crane brake system overheating, so in these cars often add all sorts of different types of auxiliary braking equipment, so as to speed up the hill stability. According to the braking energy situation, brake system can also be divided into human brake system, power brake system, and servo brake system, three. Human brake system to the drivers physical strength as braking energy; Power brake system engine power to the transformation of the air pressure or hydraulic braking energy as; And servo brake system is the most human and engine power as a brake energy. In addition, according to the braking energy transfer mode, brake system and can be divided into mechanical and hydraulic, pneumatic type and assolenoid style wait until a few kinds. In the types of brake system, the brake is car brake system to produce stop the traffic movement or movement trend components. Force At present, the kind used by car is friction brakes brake, also is to prevent the braking torque motor sports from fixed components and rotation of the friction between the work surface. 附录B制动系统作用是使行驶中的汽车按照驾驶员的要求进行强制减速甚至停车；使已停驶的汽车在各种道路条件下(包括在坡道上)稳定驻车；使下坡行驶的汽车速度保持稳定。 对汽车起制动作用的只能是作用在汽车上且方向与汽车行驶方向相反的外力，而这些外力的大小都是随机的、不可控制的，因此汽车上必须装设一系列专门装置以实现上述功能。 汽车制动系统是指为了在技术上保证汽车的安全行驶，提高汽车的平均赞叹速度等，而在汽车上安装制动装置专门的制动机构。一般来说汽车制动系统包括行车制动装置和停车制动装置两套独立的装置。其中行车制动装置是由驾驶员用脚来操纵的，故又称脚制动装置。停车制动装置是由驾驶员用手操纵的，故又称手制动装置。 行车制动装置的功用是使正在行驶中的汽车减速或在最短的距离内停车。而停车制动装置的功用是使已经停在各种路面上的汽车保持不动。但是，有时在紧急情况下，两种制动装置可同时使用而增加汽车制动的效果。有些特殊用途的汽车和经常在山区行驶的汽车，长期而又频繁地制动将导致行车制动装置过热，因此在这些汽车上往往增设各种不同型式的辅助制动装置，以便在下坡时稳定车速。 按照制动能源情况，制动系还可分为人力制动系、动力制动系、和伺服制动系等3种。人力制动系以驾驶员的体力作为制动能源；动力制动系以发动机动力所转化的气压或液压作为制动能源；而伺服制
