小編從互聯(lián)網(wǎng)上了解了一個典型案例：一輛自動上料攪拌車在轉(zhuǎn)彎的時候出現(xiàn)了嚴重的事故，據(jù)說是司機發(fā)現(xiàn)剎車踏板回縮緩慢，沒有當(dāng)回事，然后就攪拌車剎車塌塌陷，造成事故。為此，小編收集了自動上料攪拌車剎車踏板不回縮故障分析法供大家參考。

The Xiaobian learned a typical case from the Internet: an automatic feeding mixer truck had a serious accident when turning. It is said that the driver found that the brake pedal retracted slowly and did not take it seriously, and then the brake of the mixer truck collapsed, causing the accident. For this reason, Xiaobian collected the failure analysis method of brake pedal non retraction of automatic feeding mixer truck for your reference.

故障現(xiàn)象：不管怎么踩自動上料攪拌車剎車踏板，踏板不升高，就是無阻力

Fault phenomenon: no matter how you step on the brake pedal of the automatic feeding mixer, the pedal does not rise, that is, there is no resistance

故障分析：檢查制動液是否充足；制動的分泵、管路及接頭處是否有漏油現(xiàn)象；總油泵、分泵零部件是否有損壞；

Fault analysis: check whether the brake fluid is sufficient; Whether there is oil leakage at the brake cylinder, pipeline and joint; Whether the parts of the master oil pump and the slave cylinder are damaged;

故障現(xiàn)象：即使你把自動上料攪拌車剎車踏板踩到底，制動的效果還是不好；連續(xù)的踩剎車，效果也沒有改善，且踏板逐漸的升高

Fault phenomenon: even if you press the brake pedal of the automatic feeding mixer to the end, the braking effect is still poor; The effect is not improved when the brake is continuously pressed, and the pedal is gradually raised

故障分析：制動系統(tǒng)內(nèi)肯定有混有氣體；

Fault analysis: there must be mixed gas in the braking system;

故障現(xiàn)象：連續(xù)的踩剎車踏板，踏板回位升高，制動效果有一定的改善

Fault phenomenon: continuously depress the brake pedal, and the pedal return rises, and the braking effect is improved to a certain extent

故障分析：摩擦片與制動鼓間隙過大的原因，要及時的調(diào)節(jié)。

Fault analysis: the reason for the excessive clearance between the friction plate and the brake drum should be adjusted in time.

此外攪拌車剎車抖動這種情況多發(fā)生在老車身上，由于使用磨損，攪拌車剎車盤表面已有一定的平整度失準。所以建議根據(jù)具體情況選擇使用車床光盤工藝打磨，或更換剎車片(用于年長的攪拌車)。

In addition, the brake jitter of the mixer truck mostly occurs on the old vehicle body. Due to wear and tear, the surface of the brake disc of the mixer truck has a certain degree of flatness misalignment. Therefore, it is recommended to use the lathe disc process to polish or replace the brake pads (for older mixer trucks) according to the specific situation.

攪拌車在急剎車的時候，方向盤總會偏一邊，這種情況其實就是俗稱的“偏制動”，故障原因主要是攪拌車剎車系統(tǒng)左右分泵對剎車片的作用力不均勻引起的。但是由于攪拌車在行駛過程中制動盤轉(zhuǎn)動較快，分泵的作用不均勻，在快速摩擦?xí)r摩擦差別很小，不易察覺。

When the mixer is braked suddenly, the steering wheel always deviates to one side. This situation is actually commonly known as "partial braking". The failure is mainly caused by the uneven force of the left and right sub cylinders of the mixer brake system on the brake pads. However, due to the rapid rotation of the brake disc during the driving of the mixer truck, the effect of the cylinder is not uniform, and the friction difference is very small during the rapid friction, which is not easy to detect.

自動上料攪拌車一般出現(xiàn)這種情況的比較少，但這不代表我們對此不該重視，一旦發(fā)生類似情況就要及時的檢修維護，不然就會出現(xiàn)重大的問題。小編提醒：不要為省一點小錢而釀成大禍。關(guān)注我們http://kitchinit.com，了解更多事項。

In general, there are few such cases in the automatic feeding mixer truck, but this does not mean that we should not pay attention to it. In case of similar cases, timely repair and maintenance should be carried out, otherwise major problems will occur. Xiao Bian reminds: don't save a little money and cause a disaster.
