1、自拌混凝土攪拌車(chē)普通氣剎的駐車(chē)制動(dòng)只能在貨車(chē)靜止的情況下使用，因為其制動(dòng)力矩是作用在傳動(dòng)軸上，如果在小型攪拌車(chē)行駛當中使用，容易造成傳動(dòng)軸和后橋的嚴重超載荷，還可能因差速器殼被抱死而發(fā)生左右兩車(chē)輪的旋轉方向相反，致使貨車(chē)制動(dòng)時(shí)跑偏甚掉頭。但儲能彈簧制動(dòng)則不然，相反因為儲能彈簧駐車(chē)制動(dòng)行程大于行車(chē)制動(dòng)行程，在行車(chē)制動(dòng)力不足的情況下，還可以使用儲能彈簧助力進(jìn)行應急制動(dòng)。所以?xún)δ軓椈芍苿?dòng)不僅可以作駐車(chē)制動(dòng)，還可以作應急制動(dòng)。所以斷氣剎式制動(dòng)系統與普通氣剎相比，在制動(dòng)穩定性和性方面更勝一籌。
1. The parking brake of the ordinary air brake of the self mixing concrete mixer can only be used when the truck is stationary, because its braking torque acts on the transmission shaft. If it is used in the driving of the small mixer, it is easy to cause serious overload of the transmission shaft and the rear axle, and the rotation direction of the left and right wheels may be opposite due to the locking of the differential housing, resulting in the deviation of the truck when braking Even a U-turn. But 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, in the case of insufficient service braking force, the energy storage spring can also be used for emergency braking. Therefore, the energy storage spring brake can not only be used as parking brake, but also as emergency brake. Therefore, compared with the ordinary air brake, the air break brake system is better in braking stability and safety.
2、自拌混凝土攪拌車(chē)油剎結構簡(jiǎn)單，安裝空間小，只是需要剎車(chē)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(chē)總泵、分泵、剎車(chē)管路外，還有打氣泵、儲氣筒、高壓控制器、繼動(dòng)閥等部件，需要安裝空間大，結構較復雜，而且為了確保，后剎車(chē)分泵現在都是斷氣剎車(chē)。
2. The oil brake of self mixing concrete mixer has simple structure and small installation space. It only needs brake master cylinder, sub pump, 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 addition, in order to ensure safety, the rear brake sub cylinder is now air brake.
3、常規剎車(chē)是手剎鎖住傳動(dòng)軸，腳剎時(shí)由壓縮空氣進(jìn)入制動(dòng)氣室鎖住車(chē)輪。在手剎或傳動(dòng)軸機械故障時(shí)，手剎失靈;在氣泵、管路、儲氣筒、制動(dòng)閥任何一個(gè)部位故障時(shí)，腳剎失靈。而斷氣剎車(chē)就可有效避免這些危險
3. The conventional brake is that the hand brake locks the transmission shaft, and when the foot brake, the compressed air enters the brake chamber to lock the wheel. In case of mechanical failure of handbrake or transmission shaft, handbrake fails; in case of failure of any part of air pump, pipeline, air reservoir and brake valve, foot brake fails. The air brake can effectively avoid these dangers
4、斷氣剎制動(dòng)氣室內有個(gè)強 力彈簧，行車(chē)時(shí)壓縮空氣將彈簧頂起。手剎車(chē)就是把氣放掉，讓彈簧把剎車(chē)鎖死。行車(chē)中氣壓過(guò)低時(shí)也會(huì )產(chǎn)生剎車(chē)效應，保證。
4. There is a strong spring in the brake chamber of the air break brake, which is pushed up by compressed air when driving. The handbrake is to let the air out and let the spring lock the brake. When the air pressure is too low in driving, it will produce braking effect to ensure safety.
