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.
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.
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.
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.
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.
Mixer double-h control gearbox: double-h is a two-way air valve, one way through the sub box to achieve 184.108.40.206 gear conversion, the other way through the sub box to achieve high-speed 220.127.116.11 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.
