汽车轮毂轴承的刚度提升办法研究
Research on Stiffness Improvement Method of Automobile Hub Bearing
摘要
Abstract
Under the condition that the external dimension and internal structure of the hub bearing remain unchanged,the rigidity of the hub bearing is improved by optimizing the interference amount between the outer diameter of the hub bearing and the inner diameter of the steering knuckle,and the influence of the interference amount on the bearing rigidity is finally determined.However,the increase of the stiffness has an impact on the life of the hub bearing.By analyzing the relationship between the working clearance and the life of the bearing,it is determined that the bearing life meets the requirements when the working clearance is within the range of-0.005~0.05 mm.Then,the loading mode of the hub bearing is researched,and the stiffness is calculated through theoretical derivation,and theoretical analysis is carried out in combination with finite element simulation.Finally,the theoretical analysis is verified by the bench test.The results show that increasing the amount of interference within a certain range is beneficial to improving the stiffness,especially under low load condition,the stiffness can be improved by 20% .The experimental value is in good agreement with the theoretical value,so the stiffness of the hub bearing of this model is improved.关键词
