中科聚峰：混凝土搅拌车选择要注意什么？

一、混凝土搅拌车在底盘的选择上，

1、 In the selection of chassis of concrete mixer truck,

是。混凝土搅拌车的事故率居高不下，是因为搅拌车的运输工况一般较差，而且当今国内的搅拌车大多属于超载运输状态，给驾驶员的带来很大隐患。所以选购车辆时，驾驶室的性，车桥的承载性，刹车制动的灵敏性以及电气系统的稳定性是首要考虑的因素。

The first is security. The high accident rate of concrete mixer truck is due to the poor transportation condition of mixer truck, and most of the domestic mixer truck is overloaded transportation state, which brings great hidden danger to the safety of drivers. Therefore, the safety of the cab, the bearing capacity of the axle, the sensitivity of the brake and the stability of the electrical system are the primary factors to be considered when purchasing a vehicle.

其次是动力系统，动力系统包括发动机、变速箱、传动轴、减速中后桥，国内的主流混凝土搅拌车涵盖了从8方9方到20几方不等的装载容量，一般8到12方为三轴车，12方以上为四轴车。发动机马力选择一般为10方以下300马力左右，10方到12方选择336马力左右，12方以上选择375或者更大马力。变速箱一般选择9档带爬坡档合适。后桥为轮边减速桥，速比少4.5以上，对于西部山区，建议5.7左右。于传动轴，由于混凝土搅拌车的实际装载吨位只有20到30吨左右，所以一般的传动轴就可以，而且还能起到过载保护的作用，无需加粗。

The second is the power system. The power system includes engine, gearbox, transmission shaft and deceleration middle and rear axle. The domestic mainstream concrete mixer truck covers the loading capacity ranging from 8 square meters and 9 square meters to more than 20 square meters. Generally, 8-12 square meters are three axle vehicles, and more than 12 square meters are four axle vehicles. The engine horsepower is generally about 300 horsepower below 10 cubic meters, about 336 horsepower from 10 to 12 square meters, and 375 or more horsepower above 12 cubic meters. Gear box generally chooses 9 gear with climbing gear. The rear axle is a wheel side deceleration bridge, with a speed ratio of at least 4.5. For the western mountainous area, it is recommended to be about 5.7. As for the transmission shaft, because the actual loading tonnage of concrete mixer is only about 20 to 30 tons, the general transmission shaft can be used, and it can also play the role of overload protection, without thickening.

还有是舒适性。底盘的整体设计，如车架的造型（选购那种前宽后窄，前低后高的车架，前低后高可以保障驾驶室在车架上的稳定性，前宽后窄可以在发生碰撞时让车架吸收更多的冲击力，以此保障驾驶室内人员的），驾驶室内部的设计（包括车辆座椅的配置，卧铺的宽度，驾驶室的密封性及空间，多媒体系统的人性化），车辆前桥板簧（前桥板簧越长，在欠佳路段，车辆的颠簸越小）。

And then there is comfort. The overall design of the chassis, such as the shape of the frame (it is recommended to choose the frame with wide front and narrow rear, low front and high rear, which can ensure the stability of the cab on the frame; the front width and rear width can make the frame absorb more impact force in case of collision, so as to ensure the safety of the personnel in the cab), and the design of the interior of the cab (including the configuration of the vehicle seat and the width of the sleeper) The longer the leaf spring of the front axle of the vehicle, the smaller the bump of the vehicle in the poor road section.

二、混凝土搅拌车上装的选择主要包括罐体和液压件

2、 The selection of concrete mixer truck loading mainly includes tank body and hydraulic parts

混凝土搅拌车的功能就体现在罐体上，需要综合罐体的倾斜角度、罐体喷漆、叶片设计等多种因素综合考虑，液压件包括减速机，液压油泵，液压马达。搅拌车的液压件和发动机变速箱一样，属于核心的部件。

The function of the concrete mixer truck is embodied in the tank body, which needs to be considered comprehensively by many factors, such as the inclination angle of the tank body, the spray painting of the tank body, and the blade design. The hydraulic parts include the reducer, the hydraulic oil pump and the hydraulic motor. The hydraulic parts of mixer truck and engine gearbox are the core parts.
