Zusammenfassung:Abstract An axle assembly includes a central tube and an axle spindle. The axle spindle is fixed to the central tube. The axle spindle has a tubular first section and a tubular second section extending from the first section. The second section has an outer diameter. The second section has a bearing support surface. A tubular transition section is located between the first section and the second section. An annular shoulder portion is formed in an axial end segment of the tubular transition section adjacent the second section. The shoulder portion has at least one annular profile located in the shoulder portion between the annular shoulder surface and the bearing support surface. The annular profile is defined by a surface with a diameter not less than the outer diameter of the second section. An antilock braking system sensor bracket locator nub is integrally formed in the tubular transition section. An antilock braking system sensor bracket engages the antilock braking system sensor bracket locator nub for proper positioning of an antilock braking system sensor.
