It is composed of several parts, such as power take-off drive shaft, hydraulic oil pump, hydraulic oil motor, gear reducer, etc., and the control handle of mixing drum. The power control system of mixing drum will be described in Chapter 5.

 自动上料搅拌车现代设计方法自动上料搅拌车开发途径大体上有两种，一是完全自主开发(一般不包括底盘)的传统设计方法，另一是自主开发与选配相结合的现代设计方法。

Modern design method of automatic feeding mixer truck there are generally two ways to develop the automatic feeding mixer, one is the traditional design method of completely independent development (generally excluding chassis), the other is the modern design method combining independent development and selection.

随着网络环境下的全球采购方式的发展，自主开发与选配设计比重越来越大，这对降低成本、提高产品质量有重要意义。但无论自主开发，还是选配设计，其中现代设计方法的应用比重越来越大，推行现代设计方法的意义在于大幅度提高自动上料搅拌车技术和性能水平。

With the development of global procurement under the network environment, the proportion of independent development and optional design is increasing, which is of great significance to reduce costs and improve product quality. However, no matter independent development or optional design, the application proportion of modern design method is increasing. The significance of implementing modern design method is to greatly improve the technology and performance level of automatic feeding mixer.

自动上料搅拌车设计中占有极为重要地位的是产品的总体方案设计。总体方案设计主要包括整机结构方案的制定、总体参数的选择、搅拌筒(工作装置)及其附属装置的设计、搅拌筒驱动动力和调速性能参数的确定、底盘选择计算和制定改装要求、输送车工作稳定性分析、其他辅助装置的设计(液压系统、操纵装置、供水装置)等。

The overall design of the product is very important in the design of automatic feeding mixer. The overall scheme design mainly includes the formulation of the overall structure scheme, the selection of the overall parameters, the design of the mixing drum (working device) and its auxiliary devices, the determination of the driving power and speed regulation performance parameters of the mixing drum, the selection and calculation of the chassis and the formulation of the modification requirements, the stability analysis of the conveyor car, and the design of other auxiliary devices (hydraulic system, control device, water supply device), etc.

总体而言，机械设备(车辆)在市场中竞争力的强弱，在很大程度上取决于产品的质量，而产品的质量又在很大程度上取决于产品的设计，产品的设计质量可赋予某种产品“先天性优劣”这种关重要的本质特性。因此对绝大多数产品来说，产品的设计在保证产品质量的过程中起着头等重要的作用。

Generally speaking, the competitiveness of mechanical equipment (vehicles) in the market depends on the quality of products to a great extent, and the quality of products depends on the design of products to a great extent. The design quality of products can endow certain products with "congenital advantages and disadvantages", which is an important essential characteristic. Therefore, for the vast majority of products, product design plays an important role in the process of ensuring product quality.
