开混凝土搅拌车如何换挡?

概述:1、挂挡起步:带有高低速控制的变速箱,低速挡的传动比都是比较大的,所以我们在空车平地起步时,完全可以用三挡或者四挡起步,如果是重车
1、挂挡起步:带有高低速控制的变速箱,低速挡的传动比都是比较大的,所以我们在空车平地起步时,完全可以用三挡或者四挡起步,如果是重车或者坡路起步,就一定要用二挡了。车辆点火起步时踩死离合轻点油门,看转速表到2000转左右,放离合,松手刹,车辆起步。挂2挡,左靠边往后拉到空挡停一下,再往后拉。
1. Start in gear: for the gearbox with high-speed and low-speed control, the transmission ratio of low-speed gear is relatively large, so we can start in third gear or fourth gear when starting on empty ground. If it is a heavy vehicle or starting on a slope, we must use second gear. When the vehicle starts with ignition, step on the clutch firmly, light the accelerator, look at the tachometer to about 2000 revolutions, release the clutch, release the handbrake, and the vehicle starts. Shift to gear 2, pull back to neutral, and then pull back.
2、高速换挡:在高速路上行驶时,一般采用1-3-5的升档模式,先低速起步,再高速换挡。例如,在低速和三档起步时,踩下油门,将油门拉回到空档,换到高速,直接换到五档。当车速提高时,直接换到7档。当汽车在三档时,车速通常在25-40英里/小时之间。如果是初学者,建议一步步加快,养成好习惯。

2. High speed shift: when driving on the highway, generally adopt the 1-3-5 upshift mode, start at low speed and then shift at high speed. For example, when starting at low speed and third gear, step on the accelerator, pull the accelerator back to neutral, shift to high speed, and directly shift to fifth gear. When the vehicle speed increases, shift directly to 7th gear. When the car is in third gear, the speed is usually between 25-40 mph. If you are a beginner, it is recommended to speed up step by step and form good habits.
3、变速换挡:变速换挡要牢记加挡先加速,减挡先减速的原则。在加挡前轰油门把车速先提起来,在减挡前收油门把车速先降下来。在换挡时尽量采用两脚离合法,加挡时按照踩(离合器)、摘(空挡)、踩(离合器)、挂(高速挡)的原则,快速踩两脚离合器踏板,可以很轻松地增加挡位。
3. Variable speed shifting: keep in mind the principle of accelerating before shifting and decelerating before shifting. Raise the vehicle speed by turning off the accelerator before upshifting, and lower the vehicle speed by turning off the accelerator before downshifting. When shifting, try to use the two foot separation method. When shifting, quickly step on the two foot clutch pedal according to the principles of stepping on (clutch), taking off (neutral), stepping on (clutch) and engaging (high-speed gear), which can easily increase the gear.
4、上下坡换挡:上坡时要提前换入低速挡,尽可能不在坡路换挡,禁止在坡路中间变换高低速;下坡时禁止空挡滑行、禁止变换高低速;在时速高于30km/h时禁止换入低速挡,等等。
4. Shifting up and down the slope: when going uphill, shift into low gear in advance, do not shift on the slope as far as possible, and it is forbidden to change high and low speed in the middle of the slope; It is forbidden to slide in neutral gear and change high and low speed when going downhill; When the speed is higher than 30km / h, it is forbidden to shift into low gear, etc.
