Abstract
A half shaft connects to the mounting bracket of the wheel in a splined connection. The straight external spline of the half shaft is modified to a helical or involute external spline, in which the helix angle adopted is small. The mounting bracket of the wheel can be longitudinally advanced by hand assembly only part way onto the half shaft. The rest of the longitudinal advancement during assembly occurs by tightening the nut to completely eliminate the fit clearance between the external spline and its corresponding mating arrangement. Various road tests of vehicles verify that, when using the present invention, the nut does not loosen during use of the vehicle. The invention enables the locking force of the nut to be reduced, and assembly and maintenance are convenient.
