The gearbox of the automatic feeding mixer is not easy to use. How is it that there is always tooth beating? In fact, whether the gearbox is easy to use or not is closely related to personal operation habits. If you master the operation method well, the gearbox will be easy to operate. Let's understand the operation method of automatic feeding mixer gearbox.

攪拌車9檔帶高低檔變速箱的操作方法：高低檔在轉換時，只能在抵擋的一個檔位4和高檔的檔位5之間進行。如果跳檔操作，比如4轉6，6轉3等，副箱同步器因轉速差較大，摩擦帶會早期耗損。

Operation method of 9-gear high and low gear gearbox of mixer: when changing high and low gear, it can only be carried out between a gear 4 and a high gear 5. If shifting operation, such as 4 to 6, 6 to 3, etc., the friction belt of the synchronizer of the auxiliary gearbox will be worn out early due to the large speed difference.

如果高檔摩擦帶磨禿了，低轉高的瞬間就會聽到咔咔的打齒聲，反之亦然，這是因為同步器摩擦帶失效后齒輪的同步工作靠同步器結合齒和低檔減速齒輪或高低檔驅動齒輪的結合齒撞擊結合所致。進而會造成上述齒輪的打齒，再進而會造成副檔脫檔。

If the high-grade friction belt is worn out, the rattling sound will be heard at the moment of turning from low to high, and vice versa. This is because the synchronous work of the gear after the failure of the synchronizer friction belt depends on the impact of the coupling teeth of the synchronizer and the coupling teeth of the low-grade reduction gear or the high-grade and low-grade drive gear. This will cause the above gears to crack, and then the secondary gear will be out of gear.

自動上料攪拌車，高低檔轉換時，由一個檔區(qū)的空擋橫拍另一檔區(qū)的空擋后，必須有意識的稍等片刻，以保證副箱同步器的轉換結合成功，一般聽到轉換器發(fā)出的啪啪聲為準，然后再掛入你要轉換的目標檔位即可。如果副箱還沒有結合成功（野蠻換擋、氣路氣壓不穩(wěn)、氣路不暢等等因素），你就去掛主箱的檔位，就有可能造成副箱同步器斷銷等故障，嚴重的還會造成副箱爆裂。

For automatic feeding mixer, when shifting from high gear to low gear, it is necessary to wait for a moment consciously after the neutral gear in one gear area is horizontally patted to the neutral gear in another gear area, so as to ensure the successful combination of the conversion of the sub box synchronizer. Generally, it is subject to the crackle of the converter, and then shift into the target gear you want to switch. If the auxiliary gearbox has not been combined successfully (Rough shift, unstable air pressure, poor air circuit and other factors), you go to the gear of the main gearbox, which may cause the failure of the synchronizer of the auxiliary gearbox, such as broken pin, and even cause the explosion of the auxiliary gearbox.

攪拌車是單H操縱的變速箱：這種檔位只有一個空擋，所有的低檔和高檔對應的檔位都是重合位置，包括空擋在內(nèi)。因此它的高低檔轉換，無法靠橫拍實現(xiàn)，而是靠駕駛室換擋手球側面的高低檔扳鈕向下向上撥動實現(xiàn)高低檔的轉換。向下為抵擋，向上為高檔。單H閥，其實就是單路的氣閥，氣流通過推動換擋叉實現(xiàn)檔位之間的轉換。單H閥用于不帶副檔的基礎檔位的切換。

Mixer is a single H control gearbox: this kind of gear has only one neutral gear, and all gears corresponding to low gear and high gear are coincident positions, including neutral gear. Therefore, its high and low gear conversion can not be realized by horizontal racket, but by moving the high and low gear knob on the side of the cab shift handball downward and upward to realize the high and low gear conversion. Down to resist, up to high grade. The single h valve is actually a single way air valve. The air flow realizes the shift between gears by pushing the shift fork. The single h valve is used to switch the base gear without secondary gear.

攪拌車雙H操縱的變速箱：雙H就是雙路氣閥，其中一路通過副箱實現(xiàn)1.2.3.4檔轉換，另一路通過副箱實現(xiàn)高速5.6.7.8檔的轉換。雙H閥主要用于帶副箱實現(xiàn)高低檔切換和基礎檔位切換，主箱和副箱是分開的，主箱的換擋動作和副箱的換擋動作需要同時做，結合起來才是掛高速檔，所以是需要靠雙路氣閥實現(xiàn)的。

Mixer double-h control gearbox: double-h is a two-way air valve, one way through the sub box to achieve 1.2.3.4 gear conversion, the other way through the sub box to achieve high-speed 5.6.7.8 gear conversion. Double h valve is mainly used to realize high and low gear switching and basic gear switching with auxiliary box. The main box and auxiliary box are separated, and the shifting action of main box and auxiliary box need to be done at the same time. The combination is to shift to high gear, so it needs to be realized by double air valve.
