经常开搅拌车的人总是避免不了会遇到紧急情况，此时驾驶员一般都会采取急刹车的方式，那么老司机都知道在急刹车时都会离合刹车一起踩，那么这是为什么呢？

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?

在紧急情况下，人本来就会比平时有更多的误操作，因为在紧急情况下，人的大脑是处于过度兴奋的状态，在信息输入、处理和输出上，都会出现向失误方向倾斜的趋势。

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.

因此驾驶员在急刹车时，如果直踩刹车，万一误将油门当刹车踩下去，那后果可想而知，但是如果是离合刹车一起踩，那么即使误踩了油门，那踩下离合器已经将发动机动力输出切断了，发动机已经是空转状态了，起码车辆不会往前冲，也不会有更加严重的后果。

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.

现在不管是自动上料搅拌车还是其他车型都是有ABS轮胎防抱死装置，在紧急刹车时，同时踩下离合器和刹车，能确保ABS系统被正确触发，ABS系统主要有轮速传感器、制动压力调节器、电控单元和报警装置等部分构成。

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.

如果轮速传感器检测到的数据有偏差，就可能会造成ABS系统不能正确触发，在急刹车的时候，发动机转速下降的速度会比车轮慢很多，此时轮胎传感器就不能时间发出抱死信号，就会导致ABS触发不及时，急刹车时同时踩下离合器，可以切断发动机的干扰，确保ABS系统及时介入进行工作。

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.

急刹车时同时踩下离合器，能有效防止发动机熄火，这一点一般人都是知道的，因为车辆急刹车，车速下降很快，此时档位与车速就不匹配，就很容易导致发动机熄火，如果踩下离合器变速箱就处于空挡状态，就不会有车速与档位不匹配的情况。

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.

在这里搅拌车厂家提醒大家，开车一定要注意，像搅拌车这样的重型车辆惯性大，驾驶起来更加需要注意，保持车距，做好预判等等。想要了解更多内容可以电话联系我们或者关注我们的网站http://www.zkzsljbc.com，我们的工作人员会及时与您取得联系。

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.zkzsljbc.com , our staff will contact you in time.
