經常開攪拌車的人總是避免不了會遇到緊急情況，此時駕駛員一般都會采取急剎車的方式，那么老司機都知道在急剎車時都會離合剎車一起踩，那么這是為什么呢？

People who often drive mixer trucks can't avoid encountering emergencies. At this time, drivers usually take the way of emergency braking. So old drivers know that when they brake hard, they will step on the clutch brake together, so why?

在緊急情況下，人本來就會比平時有更多的誤操作，因為在緊急情況下，人的大腦是處于過度興奮的狀態，在信息輸入、處理和輸出上，都會出現向失誤方向傾斜的趨勢。

In an emergency, people will have more misoperations than usual, because in an emergency, people's brain is in a state of overexcitation, and there will be a tendency to tilt in the direction of error in information input, processing and output.

因此駕駛員在急剎車時，如果直踩剎車，萬一誤將油門當剎車踩下去，那后果可想而知，但是如果是離合剎車一起踩，那么即使誤踩了油門，那踩下離合器已經將發動機動力輸出切斷了，發動機已經是空轉狀態了，起碼車輛不會往前沖，也不會有更加嚴重的后果。

Therefore, when the driver brakes hard, if he directly steps on the brake, the consequences can be imagined if he accidentally steps on the accelerator as the brake. But if he steps on the clutch brake together, even if he accidentally steps on the accelerator, stepping on the clutch has cut off the engine power output, and the engine is already in idle state. At least the vehicle will not rush forward, and there will be no more serious consequences.

現在不管是自動上料攪拌車還是其他車型都是有ABS輪胎防抱死裝置，在緊急剎車時，同時踩下離合器和剎車，能確保ABS系統被正確觸發，ABS系統主要有輪速傳感器、制動壓力調節器、電控單元和報警裝置等部分構成。

At present, no matter the automatic feeding mixer or other models have ABS tire anti lock device. In case of emergency braking, pressing the clutch and brake at the same time can ensure that the ABS system is correctly triggered. The ABS system is mainly composed of wheel speed sensor, brake pressure regulator, electronic control unit and alarm device.

如果輪速傳感器檢測到的數據有偏差，就可能會造成ABS系統不能正確觸發，在急剎車的時候，發動機轉速下降的速度會比車輪慢很多，此時輪胎傳感器就不能第一時間發出抱死信號，就會導致ABS觸發不及時，急剎車時同時踩下離合器，可以切斷發動機的干擾，確保ABS系統及時介入進行工作。

If there is a deviation in the data detected by the wheel speed sensor, it may cause the ABS system to fail to trigger correctly. In case of emergency braking, the speed of engine speed reduction will be much slower than that of the wheel. At this time, the tire sensor cannot send a locking signal at the first time, which will lead to the delay of ABS triggering. Pressing the clutch at the same time in case of emergency braking can cut off the interference of the engine and ensure that the ABS system can intervene in time to work.

急剎車時同時踩下離合器，能有效防止發動機熄火，這一點一般人都是知道的，因為車輛急剎車，車速下降很快，此時檔位與車速就不匹配，就很容易導致發動機熄火，如果踩下離合器變速箱就處于空擋狀態，就不會有車速與檔位不匹配的情況。

It is generally known that pressing the clutch at the same time when braking hard can effectively prevent the engine from stalling. Because the vehicle brakes hard and the speed drops rapidly, the gear does not match the speed at this time, which will easily lead to the engine stalling. If you press the clutch and the gearbox is in neutral, there will be no mismatch between the speed and the gear.

在這里攪拌車廠家提醒大家，開車一定要注意安全，像攪拌車這樣的重型車輛慣性大，駕駛起來更加需要注意，保持安全車距，做好預判等等。想要了解更多內容可以電話聯系我們或者關注我們的網站http://www.www.boy7up.cn，我們的工作人員會及時與您取得聯系。

Here, the mixer truck manufacturer reminds you that you must pay attention to safety when driving. Heavy vehicles such as mixer trucks have large inertia, so you need to pay more attention when driving, maintain a safe distance between vehicles, and make a good prediction, etc. For more information, you can contact us by phone or follow our website http://www.www.boy7up.cn , our staff will contact you in time.
