Many users don't know what parts the mixer loader should have. The following small series will introduce it to you:

一、发动机。1、 Engine.

二、变矩器上有三个泵分别是工作泵、转向泵以及变速泵。

2、 There are three pumps on the torque converter, which are work pump, steering pump and transmission pump.

三、工作液压油路、液压油箱、多路阀、举升油缸和翻斗油缸。

3、 Working hydraulic oil circuit, hydraulic oil tank, multi-way valve, lifting cylinder and tipping cylinder.

四、变速箱油底壳油，行走泵，一路进变矩器一路进档位阀，变速箱离合器。这些属于行走油路。

4、 Transmission oil pan oil, travel pump, one way to the torque converter, one way to the gear valve, transmission clutch. These belong to the walking oil circuit.

五、传动轴，主差速器，轮边减速器。这些属于驱动。

5、 Transmission shaft, main differential, wheel reducer. These are drivers.

六、油箱，转向泵，稳流阀、转向器，转向油缸。这些属于转向油路。

6、 Oil tank, steering pump, steady flow valve, steering gear, steering cylinder. These belong to the steering oil circuit.

七、变速箱有一体的和分体这两种形式。

7、 The gearbox has two forms: integrated and split.

自动搅拌车轴承的设计和制作工艺，要考虑到轴承的热平衡以控制温升，因为轴承在摩擦状态下工作，由于润滑液体内部摩擦而造成功耗，转化成热量后引起轴承温升，润滑油粘度降低、间隙会改变，会使轴承的巴氏合金软化，严重时产生“烧瓦抱轴”的事故，搅拌车提高轴承的维修和装配质量，保证轴承背面光滑无斑点，定位凸点完整无损，自身的弹开量为0.5-1.5mm，这保证装配后轴瓦借助自身弹力与轴承座孔贴合紧密，转载轴承座内的上下两片轴瓦的每端均应高出轴承座平面30-50微米，高出量可保证按规定扭矩拧紧轴承盖螺栓后轴承与轴承座紧密配合，产生足够的摩擦自锁力，轴承不致松动，散热效果好，防止轴承烧蚀和磨损，轴承的工作面不能用刮配法达到75%-85%接触印痕做衡量标准，应在不刮削时就使轴承和轴径的配合间隙达到要求。

For the design and manufacturing process of the bearing of the automatic mixer truck, the thermal balance of the bearing should be considered to control the temperature rise, because the bearing works under the friction state, and the power consumption is caused by the internal friction of the lubricating liquid. After it is converted into heat, the bearing temperature rises, the viscosity of the lubricating oil decreases and the clearance will change, which will soften the Babbitt alloy of the bearing, and in serious cases, the accident of "Bush burning and shaft holding" will occur, The mixer truck improves the maintenance and assembly quality of the bearing, ensures that the back of the bearing is smooth and free of spots, the positioning convex points are intact, and its elastic opening is 0.5-1.5mm, which ensures that the bearing bush fits closely with the bearing seat hole with the help of its own elastic force, and each end of the upper and lower bearing shells in the reproduced bearing seat shall be 30-50 microns higher than the plane of the bearing seat, The excess can ensure that after tightening the bearing cover bolts according to the specified torque, the bearing fits closely with the bearing seat to produce sufficient friction self-locking force, the bearing will not be loose, the heat dissipation effect is good, and the bearing ablation and wear can be prevented. The working surface of the bearing cannot be measured by 75% - 85% contact marks by scraping method. The matching clearance between the bearing and shaft diameter should meet the requirements without scraping.

自动搅拌车的使用除了对发动机、底盘等部位进行维护外，还做好对混凝土搅拌罐及进出料口的清洗，在每次运送混凝土结束后，要及时的清洗搅拌罐及进出料斗，这样可有效减少混凝土粘附罐体的现象，可降低车辆的保养工作强度，错开生产高峰，及时的对进料斗、下料口及卸料槽进行局部的补焊，加装罐体修止口，以减少设备在进出料过程中造成的漏浆漏料现象，在保证设备完好率的基础上大限度的保证设备的整洁。

In addition to the maintenance of the engine, chassis and other parts, the use of the automatic mixer also needs to clean the concrete mixing tank and the inlet and outlet. After each delivery of concrete, the mixing tank and the inlet and outlet hopper should be cleaned in time, which can effectively reduce the phenomenon of concrete adhering to the tank body, reduce the maintenance intensity of the vehicle and stagger the production peak, Timely carry out local repair welding on the feed hopper, blanking outlet and discharge chute, and install tank body repair and stop to reduce the slurry and material leakage caused by the equipment in the process of feeding and discharging, and ensure the cleanliness of the equipment to a great extent on the basis of ensuring the integrity rate of the equipment.

自动搅拌车在使用过程中保养是必不可少的，大家在做保养的时候尽量能够面面俱到，将搅拌车的保养做到好。

The maintenance of the automatic mixer is essential in the process of use. When doing the maintenance, we should try to be comprehensive and do a good job in the maintenance of the mixer.
