道路车辆.轮子.螺母支承面强度试验

[中文适用范围]： 本国际标准规定了评估乘用车、轻型卡车和多用途车辆车轮螺母座强度的试验方法。 虽然该测试可确保螺母座的最小强度，但车轮还必须具有一定程度的灵活性以允许扭矩保持。 该测试评估螺母座的轴向强度。 此外，资料性附录提供了推荐的轴承面积，以确保将螺母拧紧到螺母座上时产生足够的旋转力。 [外文原描述]： ISO 15172:2005 specifies a test method to evaluate the strength of the nut seat of wheels intended for use on passenger cars, light trucks and multi-purpose vehicles. While this test ensures the minimum strength of the nut seat, the wheel must also have a degree of flexibility to allow torque retention. This test evaluates the axial strength of the nut seat. In addition, an informative annex provides recommended bearing area to ensure enough strength for the rotational force in tightening a nut against the nut seat.
