SAE J1095_200910

This SAE Recommended Practice provides uniform laboratory procedures for fatigue testing of wheels for demountable rims and hubs intended for normal highway use on trucks, buses, truck trailers, and multipurpose passenger vehicles. The hubs included have bolt circle diameters from 165.1 to 335.0 mm (6.50 to 13.19 in). It is up to each hub and/or wheel for demountable rims developer to determine what test method, accelerated load factor and cycle life requirements are applicable to obtain satisfactory service life in a given application. When deviations from the procedures recommended herein are made, it is the responsibility of the hub and/or wheel for demountable rims developer to modify other parameters to obtain satisfactory service life. During the 5-year review we added the test fixture adapter dimensions for metric mounting systems XVII and XVIII along with the mounting nut torque values for the M14X2, 2-piece flange nut which makes this document consistent with SAE J694. We also upgraded Table 2 "Mounting Nut Torques for Laboratory Wheel/Rim Tests", and Table 3 "Static Loaded Radii for Bending Moment Calculation" to be consistent with the tables in SAE J267. Also, the nomenclature for the spoke wheel was changed to wheel for demountable rims. The angular cornering fatigue test (40 degree) method and the dynamic radial fatigue test method were removed from this document as they are no longer being used.
