In addition to the brake master cylinder, sub cylinder and brake pipeline, the air brake also has air pump (connected with the engine through belt), air reservoir, high-pressure controller (regulating the pressure, the vehicle can reach 8 atmospheres), relay valve and other components. It needs large installation space and complex structure. In order to ensure the danger, the rear brake sub cylinder is now air cut-off brake (increased cost and complex structure).

因此有这些原因，一般油刹大都在中小型汽车，体积小、结构简单，本身车轻，不需要太大的力度，近几年有向中型车发展的趋势(载重在10吨以下，一些19座以下的中型客车，都采用油刹)。气刹大都在大型货车、大客车、混凝土搅拌车上使用，车大有空间、需要的刹车力度大，使用距离长，反应速度需要快，增加的费用反映在整台车上所占比例也不多。

Therefore, for these reasons, the general oil brakes are mostly used in small and medium-sized vehicles, which are small in size, simple in structure, light in themselves and do not need too much strength. In recent years, there is a trend towards medium-sized vehicles (oil brakes are used for medium-sized buses with a load of less than 10 tons and some less than 19 seats). Air brakes are mostly used on large trucks, buses and concrete mixers. The car has a lot of space, needs large braking force, long service distance and fast response speed. The increased cost is reflected in the whole car, and the proportion is not large.

下面我们来讲讲自上料搅拌车的断气刹与油刹有什么样的区别。

Now let's talk about the difference between the air brake and the oil brake of the self loading mixer.

1、普通气刹的驻车制动只能在货车静止的情况下使用，因为其制动力矩是作用在传动轴上，如果在自上料搅拌车行驶当中使用，易造成传动轴和后桥的严重超载荷，还可能因差速器壳被抱死而发生左右两车轮的旋转方向相反，致使货车制动时跑偏甚掉头。

1. The parking brake of ordinary air brake can only be used when the truck is stationary, because its braking torque acts on the transmission shaft. If it is used during the driving of self loading mixer truck, it is easy to cause serious overload load on the transmission shaft and rear axle. It may also happen that the rotation directions of the left and right wheels are opposite due to the locking of differential housing, resulting in deviation or even turning when the truck is braking.

2、但储能弹簧制动则不然，相反因为储能弹簧驻车制动行程大于行车制动行程，在行车制动力不足的情况下，还可以使用储能弹簧助力进行应急制动。所以储能弹簧制动不仅可以作驻车制动，还可以作应急制动。所以断气刹式制动系统与普通气刹相比，在制动稳定性和危不危险性方面更胜一筹。

2. However, the energy storage spring braking is not the case. On the contrary, because the parking braking stroke of the energy storage spring is greater than the service braking stroke, when the service braking force is insufficient, the energy storage spring can also be used for emergency braking. Therefore, the energy storage spring brake can be used not only as parking brake, but also as emergency brake. Therefore, compared with ordinary air brake, the air brake system is better in braking stability and danger.

3、油刹结构简单，安装空间小，只是需要刹车总泵、分泵、油杯及连接管路，不需要其他的附属设备;气刹就复杂多了，除了刹车总泵、分泵、刹车管路外，还有打气泵、储气筒、高压控制器、继动阀等部件，需要安装空间大，结构较复杂，而且为了确保危不危险，后刹车分泵现在都是断气刹车。

3. The oil brake has simple structure and small installation space. It only needs the brake master cylinder, slave cylinder, oil cup and connecting pipeline, and does not need other auxiliary equipment; The air brake is much more complicated. In addition to the brake master cylinder, sub cylinder and brake pipeline, there are also air pump, air reservoir, high-pressure controller, relay valve and other components, which need large installation space and complex structure. In order to ensure whether it is dangerous or not, the rear brake sub cylinder is now air cut-off brake.

3、常规刹车是手刹锁住传动轴，脚刹时由压缩空气进入制动气室锁住车轮。在手刹或传动轴机械故障时，手刹失灵;在气泵、管路、储气筒、制动阀任何一个部位故障时，脚刹失灵。而断气刹车就可避免这些危险

3. Conventional braking is to lock the transmission shaft with the hand brake, and when the foot brake is applied, the compressed air enters the brake air chamber to lock the wheels. In case of mechanical failure of hand brake or transmission shaft, the hand brake fails; When any part of the air pump, pipeline, air reservoir and brake valve fails, the foot brake fails. These dangers can be avoided by cutting off the air brake

4、断气刹制动气室内有个弹簧，行车时压缩空气将弹簧顶起。手刹车就是把气放掉，让弹簧把刹车锁死。行车中气压过低时也会产生刹车效应。

4. There is a spring in the brake chamber of the air brake, which is jacked up by compressed air during driving. The handbrake is to release the air and let the spring lock the brake. Braking effect will also occur when the air pressure is too low during driving.
