一般新用户在刚刚接触装有变速箱的自动上料搅拌车时，常反映车起步不好挂档，这是因为不了解变速箱的操作特点所致。下面自动上料搅拌车厂家为您讲解一番。

Generally, when new users are just exposed to the automatic feeding mixer equipped with a gearbox, they often report that it is difficult to start the vehicle and engage the gear, because they do not understand the operating characteristics of the gearbox. Next, the manufacturer of the automatic feeding mixer will explain it to you.

如果变速箱主箱没有同步器，起步挂档需利用离合器制动器配合工作。如果仅将离合器踏板踏下而没有顶开离合器制动器开关阀，那么制动器不起作用，挂档困难。

If there is no synchronizer in the main box of the transmission, the clutch brake shall be used for cooperation when starting and engaging the gear. If the clutch pedal is only depressed and the clutch brake switch valve is not pushed open, the brake will not work and it is difficult to engage the gear.

如果离合器踏板已将制合器开关阀顶开，而起步档仍然难挂则说明离合器制动系统有故障，此时应先检查制动气路，将制动阀变速箱左侧下方接头松开，踏下离合器踏板到顶开离合器制动阀的位置，观察气管接头如排气不畅，说明制动器开关阀故障应予拆检或更换。

If the clutch pedal has jacked the brake switch valve open, but the starting gear is still difficult to engage, it indicates that the clutch brake system is faulty. At this time, check the brake air circuit first, loosen the connector from the brake valve to the lower left side of the transmission, step down the clutch pedal to the position where the clutch brake valve is jacked open, and observe that if the air pipe connector is not vented smoothly, it indicates that the brake switch valve is faulty and should be disassembled or replaced.

如果排气通畅，需拆检离合器制动气缸，观察制动气缸密封圈是否磨损漏气、活塞是否移动自如没有发卡的现象，如果漏气则需更换“O”型圈，后检查活塞制动圆弧凹面是否磨损严重，如果磨损严重需更换制动缸活塞。

If the exhaust is smooth, it is necessary to disassemble and inspect the clutch brake cylinder, observe whether the sealing ring of the brake cylinder is worn and leaking, and whether the piston moves freely without jamming. If it leaks, replace the "O" ring, and then check whether the concave surface of the piston brake arc is worn seriously. If it is worn seriously, replace the brake cylinder piston.

如果发现汽车正常行驶时换档困难，那么应先检查是否是远距离操纵换档杆系的故障、如果换档杆系调整不当或是联接接头漏气都会产生增大换档阻力和换档困难的故障。特别是某些档位挂档困难，可调整变速箱上换档拐臂支承调整螺杆，使操纵杆系处于合适的位置。

If it is difficult to shift when the car is driving normally, first check whether it is the fault of the remote control shift lever system. If the shift lever system is improperly adjusted or the coupling connector leaks air, it will cause the fault of increasing the shift resistance and shifting difficulty. In particular, it is difficult to engage some gears. Adjust the adjusting screw rod of the shift crank arm support on the gearbox to make the control lever system at a proper position.

如果将远距离操作杆系与变速箱换档拐臂脱离，用直接操作换档拐臂的方式换档，仍然发现某些位换档困难，则说明故障在变速箱内部，需要解体检查。

If the remote operation lever system is separated from the shift lever arm of the transmission and the shift lever arm is directly operated to shift gears, it is still difficult to shift some gears, which indicates that the fault is inside the transmission and needs to be disassembled for inspection.

一般来讲是由于变速箱盖的换档轴变形、啮合套与二轴变形或过度磨损，或是换档轴与拨块的锁销松动造成的。更多相关内容就来我们网站http://www.jfhntjbc.com咨询了解吧！

Generally speaking, it is caused by deformation of the shift shaft of the gearbox cover, deformation or excessive wear of the engagement sleeve and the secondary shaft, or looseness of the lock pin between the shift shaft and the shift block.
