故障现象:一辆解放CA1121型汽车,行驶中传动轴发出尖叫异响,同时当换挡时还会发出碰击声。故障检查:传动轴异响的最常见原因是万向节状况不良。声音在传动轴和驱动桥连接处最响,做好记号拆下传动轴,拧开滑动叉油封盖,把花键轴从滑动叉内拔出,取下油封、油封垫片、油封盖,用卡环钳取出万向节耳孔内的弹性挡圈,左手把传动轴的一端抬起,右手拿手锤轻敲耳根部,将滚针轴承从耳孔中震出,再将传动轴转动180度,用同样办法将另一个滚针轴承震出,取下凸缘叉,发现一面滚针已磨断,十字轴轴颈压痕深度超过极限值0.10毫米,拆下并检查其余滚针轴承都有或多或少的磨损。
Symptom: A liberation of CA1121 cars, driving shaft drifting scream abnormal noise, while the shift will be issued when the impact noise. Troubleshooting: The most common cause of abnormal sound transmission shaft is the bad condition of the universal joint. The sound at the drive shaft and drive axle connections at the loudest, make a mark remove the drive shaft, unscrew the slide fork oil cap, the spline shaft from the slide fork, remove the oil seal, oil seal gasket, oil seal with Snap ring pliers out of the ears of universal joints within the elastic ring, lift the left hand end of the shaft, the right hand hammer knock ear, the needle bearing from the ear hole in the shock, and then the drive shaft rotated 180 degrees with The same way the other needle bearing vibration, remove the flange fork and found a needle has been worn, cross-shaft neck indentation depth exceeds the limit of 0.10 mm, remove and check the remaining needle bearings have more or more Or less wear and tear.
