The characteristics of air brake and oil brake of small concrete mixer truck are different:

1、小型混凝土搅拌车油刹是搅拌车上用以使外界（主要是路面）在汽车某些部分（主要是车轮）施加的力，从而对其进行程度的强制制动的一系列专门装置统称为制动系统。其刹车止停距离长，反应慢，但结构简单，维修方便，价钱便宜。而混凝土搅拌车气刹是通过油压碟刹，油压传动制动，其刹车距离短，反应快，结构复杂，维修成本高，购买成本也高。

1. The oil brake of small concrete mixer truck is a series of special devices on the mixer truck, which are used to make the force exerted by the outside world (mainly the road surface) 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 the braking system. The brake has long stopping distance and slow response, but has the advantages of simple structure, convenient maintenance and low price. The air brake of concrete mixer truck 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、油刹主要是在小型混凝土搅拌车中使用，但现在很多小型混凝土搅拌车也开始使用气刹，主要原因还是客户对于混凝土搅拌车行驶刹车中人身保障的需求所致。

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 personal protection in the driving brake of concrete mixers.

其次，小型混凝土搅拌车气刹和油刹的功能也不同：

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

1、小型混凝土搅拌车油刹主要是只需要制动主泵、分泵器、油杯和连接管路。不需要其他辅助设备。气刹则要复杂得多；油刹反应速度稍慢、刹车柔和、力度小，气刹反应迅速、刹车粗暴、力度大（气压高，可以达到8个大气压）。

1. The oil brake of small concrete mixer truck 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 braking speed is gentle and the braking force is slightly atmospheric pressure, and the braking force can reach 8 times of slow braking and low atmospheric pressure.

2、小型混凝土搅拌车气刹大都用在大中型重量型混凝土搅拌车上，车大有空间，制动力大，距离远，反应速度快，增加的成本体现在整车的比例上。主制动泵一般安装在制动踏板和轿底下面。制动泵前制动泵在前桥上，后制动弹簧缸在驱动车轮的桥上。

2. The air brake of small concrete mixer truck is mostly used in large and medium-sized weight concrete mixer truck. The truck has 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.
