一辆 CA141汽车,因传动轴异响进厂报修,经检查发现传动轴中间轴承支架固定螺栓松动,胶环损坏,中间轴承磨损严重。更换传动轴中间轴承支架总成后,经过路试响声消除。该车行驶1000km 左右,又出现传动轴异响。进厂检查发现,传动轴中间轴承支架固定螺栓全部松动,中间轴承烧损变色。针对连续两次传动轴中间轴承损坏而出现异响现象,我们进行了认真分析,认为可能是以下原因造成:传动轴动不平衡;传动轴弯曲;传动轴纵向位
A CA141 car, because the transmission shaft abnormal noise into the factory repair, inspection found that the middle of the drive shaft bracket bearing bolts loose, plastic ring damage, the middle bearing wear serious. Replace the drive shaft bearing bracket assembly, after the road test sound elimination. The car driving around 1000km, there are transmission shaft abnormal sound. Into the factory inspection found that the middle of the drive shaft bearing bracket bolts are loose, the middle bearing burning discoloration. In view of the fact that there are abnormal sound phenomena in the middle of two successive drive shaft bearings damaged, we conducted a careful analysis that may be caused by the following reasons: the drive shaft imbalance; drive shaft bending; drive shaft longitudinal position
