As an indispensable professional transportation tool for urban construction roads, bridges, houses, water conservancy projects and mixing plants, small concrete mixer has the characteristics of narrow body, short wheelbase, small turning radius and other personalized design, and has strong advantages in the working environment of height limit, width and length. At present, there are two braking modes: air brake and oil brake in the braking operation system of small concrete mixer. What is the difference between them? Let's move on.

土攪拌車油剎是攪拌車上用以使外界（主要是路面）在汽車某些部分（主要是車輪）施加的力，從而對其進行程度的強制制動的一系列專門裝置統稱為制動

The oil brake of soil mixer truck is a series of special devices on the mixer truck, which are used to make the force exerted by the outside (mainly the road) on some parts of the vehicle (mainly the wheels), so as to carry out the degree of forced braking, which is collectively referred to as braking

，小型混凝土攪拌機氣剎和油剎的特點不同：

Firstly, the characteristics of air brake and oil brake of small concrete mixer are different:

1、小型混凝土攪拌機油剎是攪拌車上用以使外界（主要是路面）在汽車某些部分（主要是車輪）施加的力，從而對其進行程度的強制制動的一系列專門裝置統稱為制動系統。其剎車止停距離長，反應慢，但結構簡單，維修方便，價格便宜。

1. The oil brake of small concrete mixer is a series of special devices on the mixer to make the external (mainly road surface) exert force on some parts of the vehicle (mainly wheels), so as to carry out the degree of forced braking, which is collectively referred to as the braking system. The utility model has the advantages of long braking stopping distance, slow response, simple structure, convenient maintenance and low price.

而混凝土攪拌機氣剎是通過油壓碟剎，油壓傳動制動，其剎車距離短，反應快，結構復雜，維修成本高，購買成本也高。

The air brake of concrete mixer is through oil pressure disc brake and oil pressure transmission brake. It has the advantages of short braking distance, fast response, complex structure, high maintenance cost and high purchase cost.

2、油剎主要是在小型混凝土攪拌機中使用，但現在很多小型混凝土攪拌車也開始使用氣剎，主要原因還是客戶對于混凝土攪拌機行駛剎車的需求所致。

2. The oil brake is mainly used in small concrete mixers, but now many small concrete mixers also start to use the air brake, mainly due to the customer's demand for the driving brake safety of the concrete mixer.

其次，小型混凝土攪拌機氣剎和油剎的功能也不同：

Secondly, the functions of air brake and oil brake of small concrete mixer are also different:

1、小型混凝土攪拌機油剎主要是只需要制動主泵、分泵器、油杯和連接管路。不需要其他輔助設備。氣剎則要復雜得多；油剎反應速度稍慢、剎車柔和、力度小，氣剎反應迅速急、剎車粗暴、力度大（氣壓高，可以達到8個大氣壓）。

1. The oil brake of small concrete mixer only needs to brake the main pump, sub pump, oil cup and connecting pipeline. No other auxiliary equipment is required. Air brake is much more complicated; The reaction speed of the oil brake is slightly slow, the braking is soft, the strength is small, the reaction of the air brake is rapid and urgent, the braking is rough, and the strength is large (the air pressure is high, which can reach 8 atmospheres).

2、小型混凝土攪拌機氣剎大都用在大中型重量型混凝土攪拌車上，車大有空間，制動力大，距離遠，反應速度快，增加的成本體現在整車的比例上。主制動泵一般安裝在制動踏板和轎底下面。制動泵前制動泵在前橋上，后制動彈簧缸在驅動車輪的橋上

2. The air brakes of small concrete mixers are mostly used on large and medium-sized weight concrete mixers, which have large space, large braking force, long distance and fast reaction speed. The increased cost is reflected in the proportion of the whole vehicle. The main brake pump is generally installed under the brake pedal and car bottom. Brake pump the front brake pump is on the front axle and the rear brake spring cylinder is on the axle driving the wheel
