小型混凝土搅拌机副车架是主要的承重部分，作业时的载荷几乎都是通过它来支撑，加上在行使中由于路面的颠簸和加、减速形成的冲击载荷，都对副车架的结构提出很高的要求。下面就来认识下这个部件吧。

The subframe of small concrete mixer is the main load-bearing part, and the load during operation is almost supported by it. In addition, the impact load formed by the bumpiness of the road and acceleration and deceleration during driving puts forward high requirements for the structure of the subframe. Let's get to know this part.

整个副车架由主梁、前台支撑架、后台支撑架组成。

The whole subframe is composed of the main beam, the front support frame and the back support frame.

主梁采用整体箱型结构梁，从根本上增强了它的抗扭、抗折、抗拉性能，保证了刚性要求，在两根主梁之间加装辅助横梁，调整主梁各段的刚性，让载荷在副车架整个长度上更均匀的分布。

The main beam adopts an integral box structure beam, which fundamentally enhances its torsional, flexural and tensile properties, and ensures the rigidity requirements. An auxiliary beam is added between the two main beams to adjust the rigidity of each section of the main beam, so that the load is more evenly distributed over the whole length of the subframe.

在行使过程中不可避免会遇到特殊情况而采取紧急制动，由此所带来的惯性力是非常大的，加上搅拌筒本身有一定的倾角，所以副车架前台承受的载荷相对来说要大得多，而这一部分载荷主要加在联接减速机与前支撑座的六个螺栓上，为防止螺栓发生被剪断而酿成事故，在前支撑台加装止推挡块，使螺栓不受到剪切力的影响，确保车辆运行中的。

In the process of driving, it is inevitable to adopt emergency braking in case of special circumstances, and the inertia force caused by this is very large. In addition, the mixing drum itself has a certain inclination angle, so the load borne by the front desk of the subframe is relatively much larger, and this part of the load is mainly added to the six bolts connecting the reducer and the front support seat. In order to prevent the bolts from being cut off and causing accidents, thrust blocks are added to the front support platform, The bolts shall not be affected by the shear force to ensure the safety of the vehicle during operation.

为满足小型混凝土搅拌机的填充率，搅拌筒还要满足一定的倾角要求。搅拌筒、减速机和前台支撑架在装配后已经固连为一体，由于制造的误差有可能后台支撑架在装配后满足不了倾角的要求，无法对搅拌筒产生有效的支撑。

In order to meet the filling rate of small-scale concrete mixer, the mixing drum must meet certain inclination requirements. The mixing drum, reducer and front stage support frame have been firmly connected after assembly. Due to manufacturing error, the rear stage support frame may not meet the requirements of inclination after assembly, and cannot effectively support the mixing drum.

这时整个结构就相当于一个悬臂梁。这对于减速机来说会产生很大的扭转力矩。为防止由此给减速机带来的危害，支重滚轮在后台支撑架上的安装位置可以调节。而且在装配调试完成后，加装固定挡块，防止由于螺栓松动引起支重轮偏移。

At this time, the whole structure is equivalent to a cantilever beam. This will produce a large torsional moment for the reducer. In order to prevent the damage to the reducer, the installation position of the supporting roller on the backstage support frame can be adjusted. Moreover, after the assembly and commissioning are completed, a fixed stopper shall be installed to prevent the deflection of the roller due to the loosening of the bolts.
