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).

因此有這些原因，一般油剎大都在中小型汽車，體積小、結構簡單，本身車輕，不需要太大的力度，近幾年有向中型車發展的趨勢(載重在10噸以下，一些19座以下的中型客車，都采用油剎)。氣剎大都在大型貨車、大客車、混凝土攪拌車上使用，車大有空間、需要的剎車力度大，使用距離長，反應速度需要快，增加的費用反映在整臺車上所占比例也不多。

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.

下面我們來講講自上料攪拌車的斷氣剎與油剎有什么樣的區別。

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

1、普通氣剎的駐車制動只能在貨車靜止的情況下使用，因為其制動力矩是作用在傳動軸上，如果在自上料攪拌車行駛當中使用，易造成傳動軸和后橋的嚴重超載荷，還可能因差速器殼被抱死而發生左右兩車輪的旋轉方向相反，致使貨車制動時跑偏甚至掉頭。

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、但儲能彈簧制動則不然，相反因為儲能彈簧駐車制動行程大于行車制動行程，在行車制動力不足的情況下，還可以使用儲能彈簧助力進行應急制動。所以儲能彈簧制動不僅可以作駐車制動，還可以作應急制動。所以斷氣剎式制動系統與普通氣剎相比，在制動穩定性和危不危險性方面更勝一籌。

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、油剎結構簡單，安裝空間小，只是需要剎車總泵、分泵、油杯及連接管路，不需要其他的附屬設備;氣剎就復雜多了，除了剎車總泵、分泵、剎車管路外，還有打氣泵、儲氣筒、高壓控制器、繼動閥等部件，需要安裝空間大，結構較復雜，而且為了確保危不危險，后剎車分泵現在都是斷氣剎車。

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、常規剎車是手剎鎖住傳動軸，腳剎時由壓縮空氣進入制動氣室鎖住車輪。在手剎或傳動軸機械故障時，手剎失靈;在氣泵、管路、儲氣筒、制動閥任何一個部位故障時，腳剎失靈。而斷氣剎車就可避免這些危險

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、斷氣剎制動氣室內有個彈簧，行車時壓縮空氣將彈簧頂起。手剎車就是把氣放掉，讓彈簧把剎車鎖死。行車中氣壓過低時也會產生剎車效應。

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.
