變速箱是車輛非常重要的部件，它可以改變傳動(dòng)比，擴(kuò)大驅(qū)動(dòng)輪的扭矩和速度功能。那么汽車變速箱的功能如何？
濟(jì)南自動(dòng)變速箱維修人員為您解答。
The gearbox is a very important part of the vehicle. It can change the transmission ratio and expand the torque and speed functions of the drive wheels. What are the functions of the automobile gearbox? Jinan automatic transmission maintenance personnel will answer for you.
汽車變速箱的功能:
Functions of automobile gearbox:
1.改變傳動(dòng)比，擴(kuò)大驅(qū)動(dòng)輪的扭矩和速度范圍，以適應(yīng)頻繁變化的行駛條件，同時(shí)使發(fā)動(dòng)機(jī)在有利的工況下工作(更高的轉(zhuǎn)速和更低的油耗)；
1. Change the transmission ratio, expand the torque and speed range of the driving wheel to adapt to the frequently changing driving conditions, and enable the engine to work under favorable working conditions (higher speed and lower fuel consumption);
2.在發(fā)動(dòng)機(jī)旋轉(zhuǎn)方向不變的情況下，汽車可以向后行駛；
2. Under the condition that the rotation direction of the engine is unchanged, the car can run backward;
3.用空擋中斷動(dòng)力傳遞，使發(fā)動(dòng)機(jī)能啟動(dòng)和怠速，方便變速器換擋或輸出動(dòng)力。
3. Use neutral gear to interrupt power transmission, so that the engine can start and idle, facilitating transmission shifting or power output.
此外每個(gè)齒輪都有不同的傳動(dòng)比，這意味著小齒輪和大齒輪的嚙合可以產(chǎn)生不同的速度。低速行駛時(shí)，使用低傳動(dòng)比(3檔及以下)，大軸轉(zhuǎn)速低于發(fā)動(dòng)機(jī)轉(zhuǎn)速。根據(jù)公式P=FV，可以得到更大的驅(qū)動(dòng)力。高速行駛時(shí)，使用高傳動(dòng)比(4檔及以上)，降低牽引力以獲得更高的速度。切割齒輪時(shí)，可以選擇不同尺寸的齒輪與大軸的齒輪嚙合。
In addition, each gear has a different transmission ratio, which means that the meshing of the small gear and the big gear can produce different speeds. When driving at low speed, use low transmission ratio (gear 3 and below), and the large shaft speed is lower than the engine speed. According to the formula P=FV, a greater driving force can be obtained. When driving at high speed, use high transmission ratio (4th gear and above) to reduce the traction force to obtain higher speed. When cutting gears, you can select gears of different sizes to mesh with the gear of the big shaft.
