Retaining a brake rotor in an vehicle corner apparatus |
摘要 |
A vehicle corner apparatus and method of fabricating a vehicle corner apparatus, utilize a wheel spindle adapted for receiving a self-tapping screw for securing a brake rotor to the wheel spindle. Using a self-tapping screw allows manufacturing and assembly costs to be significantly reduced, in comparison to prior vehicle corners that used a machine screw and a threaded hole in a wheel spindle for securing a rotor to the spindle, and provides greater assurance that the lateral run out of the brake rotor will be maintained at a lower value than can be achieved in prior vehicle corners. The wheel spindle includes a retaining screw hole having a conical web adapted to receive and facilitate installation and increase holding force of the self-tapping screw. The retaining screw hole may also include a counter bore for receipt of a locator pin that is used during subsequent formation of wheel bolt holes in the spindle. The rotor retention screw hole for the self-tapping screw, with or without the counter bore, may be formed by a simple sequence of operations using a pair of coining punches.
