Most special purpose vehicle gearboxes are manual gears, such as self-contained mixer, truck crane, wrecker, etc. When shifting gears, the vehicle may feel frustrated. Why?

換擋受挫的原因：自裝式攪拌機(jī)在行駛過(guò)程中換擋時(shí)，如果發(fā)動(dòng)機(jī)轉(zhuǎn)速與當(dāng)前的車輛速比匹配，即發(fā)動(dòng)機(jī)轉(zhuǎn)速與離合器片轉(zhuǎn)速之間存在速度差(多數(shù)情況下，發(fā)動(dòng)機(jī)轉(zhuǎn)速低于離合器片轉(zhuǎn)速)，那么就會(huì)發(fā)生受挫。所以造成車輛換擋受挫的原因是：當(dāng)時(shí)換擋時(shí)發(fā)動(dòng)機(jī)轉(zhuǎn)速與車速不匹配，發(fā)動(dòng)機(jī)轉(zhuǎn)速與離合器片轉(zhuǎn)速存在速度差。比如，在車輛行駛過(guò)程中，要想急劇加速，要深踩油門踏板。這時(shí)變速箱會(huì)自動(dòng)降檔，提高發(fā)動(dòng)機(jī)轉(zhuǎn)速，到一定高度再換高檔。換上高速檔后，因?yàn)檐囁贂?huì)明顯下降，會(huì)產(chǎn)生相當(dāng)明顯的挫敗感。要想保持更好的加速性能，就必須深踩油門踏板，變速箱就會(huì)以更高的速度升到更高的檔位。這時(shí)，轉(zhuǎn)移的挫敗感更加明顯。
              

Reasons for frustration in shifting: if the engine speed matches the current vehicle speed ratio when the self-contained mixer is shifting, that is, there is a speed difference between the engine speed and the clutch plate speed (in most cases, the engine speed is lower than the clutch plate speed), then frustration will occur. Therefore, the reason for the frustration of vehicle shifting is that the engine speed does not match the vehicle speed when shifting, and there is a speed difference between the engine speed and the clutch plate speed. For example, in the process of vehicle driving, if you want to accelerate sharply, you should first step on the accelerator pedal deeply. At this time, the gearbox will automatically downshift, increase the engine speed, and then shift to high gear at a certain height. After shifting to high gear, the vehicle speed will obviously decrease, which will cause quite obvious frustration. In order to maintain better acceleration performance, it is necessary to press the accelerator pedal deeply, and the transmission will rise to a higher gear at a higher speed. At this time, the frustration of transfer is more obvious.

方案：一個(gè)更好的方法來(lái)加載混合器的挫敗感，就是在每次換檔時(shí)，離合器輸入端和輸出端的齒輪速度完全相似。雖然有點(diǎn)難，但是有經(jīng)驗(yàn)的老司機(jī)開車比較多，知道每個(gè)檔位的車速和發(fā)動(dòng)機(jī)的轉(zhuǎn)速大致的速度差。找機(jī)會(huì)平穩(wěn)換擋。手動(dòng)換擋的速度不可能每次都掌握的那么準(zhǔn)確。有的老司機(jī)先把離合器抬起70%，讓離合器減半。

Solution: a better way to eliminate the frustration of the loading mixer is that the gear speeds at the input and output ends of the clutch are exactly the same at each shift. Although it's a little difficult, experienced drivers drive more and know the speed difference between each gear and the engine speed. Find a chance to shift smoothly. It's impossible to master the speed of manual shift every time. Some old drivers first lift the clutch 70% to halve the clutch.
