  1故障现象
  1 fault phenomenon
  一辆东风二手洒水车经过三次保养,在测试车变速器五次(直接控制)运行中跳闸至中性故障。现象是当五挡进入驱动后,变速杆有继续向后移动的趋势(五控位置在后面)。当油门踏板松开时,变速杆向前翻转到空档。即使用手按住变速杆也无济于事。
  After three times of maintenance, a Dongfeng second-hand sprinkler trips to neutral fault during five times of transmission (direct control) operation of test vehicle. The phenomenon is that when the fifth gear enters the drive, the shift lever will continue to move backward (the fifth control position is at the back). When the accelerator pedal is released, the shift lever is turned forward to neutral. It's no use holding down the gear lever with your hand.

  维修时,将变速杆拨至五挡,柴油机熄火。打开变速器盖检查,齿轮啮合位置是否正确,轴承是否松动,第四、五挡同步器推环总成是否松动,拨叉无变形,拨叉端与第四、五挡滑动套和槽间隙是否正常。还要检查一下换挡件的定位装置,是否完好。
  During maintenance, shift the gearshift lever to five gears, and the diesel engine stalls. Open the transmission cover to check whether the gear engagement position is correct, whether the bearing is loose, whether the fourth and fifth gear synchronizer push ring assembly is loose, whether the shift fork is not deformed, and whether the clearance between the shift fork end and the fourth and fifth gear sliding sleeves and grooves is normal. Also check whether the positioning device of the shift piece is in good condition.
  为此,对变速器从小车上取下,彻底分解进行全面检查。更换可疑部件,重新组装和调整。经过重新测试,五格跳格的情况并没有改变。
  Therefore, the transmission is removed from the trolley and thoroughly disassembled for overall inspection. Replace suspect parts, reassemble and adjust. After retesting, the situation of five grid jumping has not changed.
  为了判断是不是变速器出了问题,然后将同类型的变速器正常运行到汽车上,问题的结果仍然存在。
  In order to determine whether there is a problem with the transmission, and then run the same type of transmission on the vehicle normally, the result of the problem still exists.
  经以上检查,排除了传动问题的可能性。然后检查柴油机缸体曲轴的线与飞轮壳的线是否偏离太大。的模型检验:曲轴飞轮住房屁股直径152毫米孔为0.35毫米(标准的值应不超过0.2毫米),和non-perpendicularity曲轴线的外缘飞轮住房屁股应当1.5毫米(标准的值应不超过0.2毫米)。如此大的偏差,当传动装置安装固定在飞轮壳上时,传动装置必须先将轴的跳动加大。五块作为直接块,直接受轴的影响,跳块的影响并不令人意外。通过了解,汽车在三级维修中,更换了飞轮外壳。
  Through the above inspection, the possibility of transmission problem is eliminated. Then check whether the center line of the crankshaft of the diesel engine block deviates too much from the center line of the flywheel housing. Model test: the diameter of 152 mm hole of crankshaft flywheel housing bottom is 0.35 mm (the standard value should not exceed 0.2 mm), and the outer edge of the center line of non-permeability crankshaft flywheel housing bottom should be 1.5 mm (the standard value should not exceed 0.2 mm). With such a large deviation, when the transmission device is installed and fixed on the flywheel housing, the transmission device must first increase the shaft runout. As a direct block, five blocks are directly affected by the first axis, and the influence of jumping block is not surprising. Through understanding, in the three-level maintenance of the car, the flywheel housing was replaced.
  飞轮壳后重新安装,调整和检验模型和non-perpendicuity(也就是说,缸体和飞轮壳之间的增减调整的类型),在标准范围内,传输将重新安装第二个测试车,五块跳块消除的现象。
  After the flywheel housing is reinstalled, the model and non Sustainability (that is, the type of increase and decrease adjustment between the cylinder block and flywheel housing) are adjusted and inspected. Within the standard range, the transmission will reinstall the second test vehicle and eliminate the phenomenon of five jumping blocks.
