本文对６２３套轿车前轮轮毂轴承的早期失效进行了统计分析。研究发现轿车轮毂轴承具有鲜明的失效特性。其主要失效形式为①轿车前轮轮毂所用的双到圆锥滚子轴承和双列球轴承都只有单列轴承部件发生早期失效；②大多数轴承内孔与轴径配合面有周向划痕；③除部分轴承滚道表面发生疲劳剥落外，较多轴承滚道表面发生条状等间距剥落；④多数轴承滚道表面出现等间距压痕；⑤滚动体的主要失效形式为疲劳剥落、大端出现环状划痕及点蚀；（６）部分轴承滚道表面有冲击压痕。这些失效现象与轿车轮毂的结构特征及车轮的动力学性能直接相关。作者建议轿车前轮轮毂应采用两个单列角接触轴承代替单个双列向心推力轴承。
In this paper, 623 sets of front-wheel hub bearings for the early failure of a statistical analysis. The study found that car hub bearings have distinct failure characteristics. The main failure of the form ① front wheel hub used double-tapered roller bearings and double row ball bearings are only a single row of bearing components early failure; ② most of the bearing bore and shaft with a circumferential surface scratches; ③ In addition to some bearing raceway surface fatigue spalling occurs, the more bearing raceway surface strip stripping at equal intervals; ④ most bearing raceway surface with equal spacing indentation; ⑤ rolling failure of the main form of fatigue spalling, big end Annular scratches and pitting; (6) part of the bearing surface of the raceway impact indentation. These failures are directly related to the structural characteristics of the wheel hub and the dynamic performance of the wheel. The author suggests that the front wheel hub of a sedan should use two single row angular contact bearings instead of a single double row radial thrust bearing.
