摘要
Abstract
Vehicle wheel bolt toque decreases after bolt is fastened under external load conditions.Based on the design of different test conditions,it is determined that the torque loss is not caused by the angular displacement of wheel bolt,but due to the temperature increase of bolt.It is clarified that the bolt refastened operation can effectively maintain the pre-tightening force and torque specification of the wheel bolts,and the manufacturing tolerance of the wheel bolts and hole are the main factors affecting the loss of blot tightening torque as well.关键词
