自动混凝土搅拌车的变速箱不好用，老是出现打齿现象是怎么回事，其实很多时候变速箱的好用与否跟个人的操作习惯是有密切关系的，掌握好了操作方法，变速箱就很容易操作了。一起来了解自动混凝土搅拌车变速箱的操作方法。
The gearbox of automatic concrete mixer is not easy to use. It always has teeth. 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 concrete mixer gearbox.
自动混凝土搅拌车9档带高低档变速箱的操作方法：高低档在转换时，只能在抵挡的后一个档位4和高 档的一个档位5之间进行。如果跳档操作，比如4转6，6转3等，副箱同步器因转速差较大，摩擦带会早期耗损。如果摩擦带磨秃了，低转高的瞬间就会听到咔咔的打齿声，反之亦然，这是因为同步器摩擦带失效后齿轮的同步工作靠同步器结合齿和低档减速齿轮或高低档驱动齿轮的结合齿撞击结合所致。进而会造成上述齿轮的打齿，再进而会造成副档脱档。
Operation method of 9-gear high and low gear transmission of automatic concrete mixer: when changing high and low gear, it can only be carried out between the last gear 4 and the first 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 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 gear or the high and low gear. This will cause the above gears to crack, and then the secondary gear will be out of gear.
自动混凝土搅拌车，高低档转换时，由一个档区的空挡横拍另一档区的空挡后，必须有意识的稍等片刻，以保证副箱同步器的转换结合成功，一般听到转换器发出的啪啪声为准，然后再挂入你要转换的目标档位即可。如果副箱还没有结合成功（野蛮换挡、气路气压不稳、气路不畅等等因素），你就去挂主箱的档位，就有可能造成副箱同步器断销等故障，严重的还会造成副箱爆裂。
For automatic concrete mixer, when switching between high and low gears, after the neutral gear in one gear area is horizontally patted to the neutral gear in another gear area, you must consciously wait for a moment to ensure that the conversion and combination of the secondary box synchronizer are successful. Generally, you can hear 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.
自动混凝土搅拌车是单H操纵的变速箱：这种档位只有一个空挡，所有的低档和高 档对应的档位都是重合位置，包括空挡在内。因此它的高低档转换，无法靠横拍实现，而是靠驾驶室换挡手球侧面的高低档扳钮向下向上拨动实现高低档的转换。向下为抵挡，向上为高 档。单H阀，其实就是单路的气阀，气流通过推动换挡叉实现档位之间的转换。单H阀用于不带副档的基础档位的切换。
The automatic concrete mixer truck is a single-H control gearbox: this kind of gear has only one neutral gear, and all the corresponding gears of 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.
自动混凝土搅拌车双H操纵的变速箱：双H就是双路气阀，其中一路通过副箱实现1.2.3.4档转换，另一路通过副箱实现高速5.6.7.8档的转换。双H阀主要用于带副箱实现高低档切换和基础档位切换，主箱和副箱是分开的，主箱的换挡动作和副箱的换挡动作需要同时做，结合起来才是挂高速档，所以是需要靠双路气阀实现的。对档位操作不太熟练的搅拌车司机可以参考一下。
Automatic concrete mixer double H control gearbox: Double h is a double 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. On the gear operation is not very skilled mixer driver can refer to.
The above is the reason why the gear box of the automatic concrete mixer works. I hope it can help you. For more wonderful information, please click our official website: Zhongke Jufeng https://www.cnzkjf.com .
