When driving an automatic mixing vehicle, drivers often encounter such a situation: when the engine is idling, the clutch pedal has been pressed to the bottom, but it is difficult to shift, there is a feeling that the gear is not smooth, and there is a strong impact sound of the gear change. After reluctantly engaging the gear, the clutch pedal has not been released, and the concrete mixer has been running or stalling. There are many reasons for this phenomenon. The manufacturer of Shanqi mixer truck provides the following solutions for the majority of concrete mixer truck drivers to eliminate, find the problem and solve the fault.

一、搅拌车离合器挂挡不佳的故障原因及排除方法

1、 Causes and troubleshooting of poor clutch engagement of mixer truck

通过以下方法进行检查：将离合器底盖拆下，把变速器挂入空挡，离合器踩到底。然后，用起工具拨动从动盘。如能轻松拨转，说明离合器分离良好；如拨不动，说明离合器分离不彻底。

Check through the following methods: remove the bottom cover of the clutch, put the transmission into neutral gear, and press the clutch to the bottom. Then, use the lifting tool to move the driven plate. If it can be turned easily, it means that the clutch is in good condition; if it can not be turned, it means that the clutch is not completely separated.

搅拌车离合器挂挡不佳的故障原因及排除方法

Causes and troubleshooting of poor clutch engagement of mixer truck

1、检查搅拌车离合器踏板自由行程是否过大，然后进行调整。

1. Check whether the free stroke of the clutch pedal of the mixer is too large, and then adjust it.

2、检查搅拌车分离杠杆，是否高度一致或存在过低的现象。具体方法：在车下拨动分离拨叉，使搅拌车分离轴承前端靠在分离杠杆内端面上，将离合器转动一周。如果分离杠杆内端同时和分离轴承接触不上，说明分离杠杆高度不一致，需要调整。如果高度一致，仍然分离不彻底，此时应检查杠杆高度。将各分离杠杆调到同一高度，如果分离彻底，说明原来调整不当或磨损严重。调整分离杠杆之后，离合器踏板的自由行程也必须重新调整。

2. Check whether the separation lever of mixer truck is consistent or too low. Specific methods: under the vehicle, move the release fork to make the front end of the release bearing of the mixer truck lean against the inner end face of the release lever, and rotate the clutch for a circle. If the inner end of the release lever is not in contact with the release bearing at the same time, it indicates that the height of the release lever is inconsistent and needs to be adjusted. If the height is consistent and the separation is not complete, check the lever height at this time. Adjust each separation lever to the same height. If the separation is complete, it means that the original adjustment is improper or the wear is serious. After adjusting the release lever, the free travel of the clutch pedal must also be readjusted.

3、进行上述操作后，如果还存在分离不彻底的情况，就要拆下离合器，检查主从动盘有无翘曲、从动盘是否装反、分离杠杆螺钉是否松动等。

3. After the above operation, if the separation is not complete, remove the clutch, check whether the master and slave drive plate is warped, whether the driven plate is installed reversely, whether the release lever screw is loose, etc.

4、对于新铆的摩擦片的离合器，要检查从动盘和摩擦片是否过厚。如果过厚，可在离合器盖和飞轮之间加垫片。

4. For the clutch of newly riveted friction plate, check whether the driven plate and friction plate are too thick. If it is too thick, add a gasket between the clutch cover and the flywheel.

5、对于自动搅拌一体车液压传动的离合器，除上述检查外，还应检查制动液是否缺少，管道是否渗漏并排出液压系统内的空气。

5. For the clutch of the hydraulic transmission of the automatic mixer truck, in addition to the above inspection, it is also necessary to check whether the brake fluid is lack, whether the pipeline is leaking, and exhaust the air in the hydraulic system.

二、正确利用搅拌车的离合器方法

2、 How to use correctly clutch of mixer truck

1、无事不要踩搅拌车离合器

1. Don't step on the clutch of mixer when you have nothing to do

（1）搅拌车上的离合器在正常行车时，是处在细密接合状态，离合器应无滑转；

(1) The clutch on the mixer truck is in a fine engagement state during normal driving, and the clutch should not slip;

（2）在开车时除汽车起步、换档和低速刹车需要踩下离合器踏板外，其他时间都不要没事踩离合，或把脚放在离合器踏板上；

(2) When driving, do not step on clutch pedal or put foot on clutch pedal at other time except for car starting, shifting and low-speed braking;

（3）搅拌车行车时把脚长时间放在离合器踏板上，很容易造成离合器打滑、离合器片烧蚀等现象，严重时甚使离合器压盘、飞轮端面烧蚀拉伤，导致离合器压紧弹簧退火等妨碍。同时，还会导致费油、费车，增加行车用度。

(3) When the mixer truck is driving, if the foot is placed on the clutch pedal for a long time, it is easy to cause clutch slip, clutch plate ablation and other phenomena. In serious cases, even the clutch pressure plate and flywheel end face are ablated and strained, resulting in the annealing of clutch compression spring and other obstacles. At the same time, it will also lead to fuel consumption and vehicle consumption, which will increase the driving cost.

2、搅拌车起步时的正确操纵

2. Correct operation of mixer truck when starting

（1）搅拌车起步时离合器踏板的操纵方式是“一快、二慢、三联动”,即在踏板抬起开始时快拾；

(1) When the mixer starts, the operation mode of clutch pedal is "one fast, two slow, three linkage", that is, pick up quickly when the pedal is lifted;

（2）当离合器呈现半联动时（此时动员机的声音有变革），踏板抬起的速度稍慢；

(2) When the clutch shows half linkage (at this time the voice of the mobilization machine has changed), the speed of pedal lifting is slightly slow;

（3）由联动到完全团结的历程，将踏板慢慢拾起在离合器踏板抬起的同时，按照动员机阻力巨细逐渐踩下油门踏板，使搅拌车平稳起步。

(3) From linkage to complete unity, slowly pick up the pedal. At the same time of lifting the clutch pedal, step on the accelerator pedal gradually according to the resistance of the mobilization machine, so that the mixer can start smoothly.

3、搅拌车换档时的正确操纵

3. Correct operation of agitator when shifting gears

（1）在行车中换档时，哄骗离合器踏板应迅速踩下并抬起，不要呈现半联动现象，否则，会加速离合器的磨损；

(1) When shifting gears during driving, the deceiving clutch pedal should be stepped down and raised quickly, without half linkage phenomenon, otherwise, the wear of clutch will be accelerated;

（2）操纵时要留意与油门共同。

(2) When handling, pay attention to be in common with the throttle.

4、为使搅拌车换档平顺，减轻变速器换档机构和离合器的磨损，倡导利用“两脚离合器换档法”：这种要领固然操纵较庞大，却是开车省油省钱的好要领。

4. In order to make the mixer shift smoothly and reduce the wear of the transmission shift mechanism and clutch, the "two foot clutch shift method" is advocated. Although the operation is huge, it is a good way to save fuel and money.
