A knuckle hub assembly () and a method for manufacturing same whereby brake run out is produced includes a knuckle (), a bearing () press fit into the knuckle (), and a wheel hub () coupled to the bearing () and rotateable with respect to the knuckle (). The wheel hub () has a flange surface () having a relief channel () formed therein. A plurality of wheel studs () are press fit into bolt opening () formed in the relief channel (). This arrangement provides a flat flange surface () for mating with a rotor () to minimize brake run out. The knuckle hub assembly () is mounted into a floating tool for finish turning of the flange surface () to provide minimal run out and maximum flatness.

Knuckle hub assembly and method for making same

A part clamping fixture assembly for locating and holding a wheel hub assembly for final finishing a flange face of the wheel hub includes a top portion having a bore formed therethrough. The fixture assembly includes a puller member having an upper end for communicating with a drive mechanism and a lower end opposite the upper end. The puller member has an encasing disposed therearound. The encasing has a lower portion for engaging a bearing of the wheel hub assembly and an upper portion in communication with the top portion. The fixture assembly also includes a lift mechanism for lifting the wheel hub assembly generally upward such that a surface of the bearing engages the lower end of the puller member. The lift mechanism is engageable with the lower end of the puller member such that the drive mechanism will rotate the puller member and the lift mechanism together to accomplish the final finishing of the flange face.

Wheel hub assembly fixture

A knuckle hub assembly ( ) and a method for manufacturing same whereby brake run out is produced includes a knuckle ( ), a bearing ( ) press fit into the knuckle ( ), and a wheel hub ( ) coupled to the bearing ( ) and rotateable with respect to the knuckle ( ). The wheel hub ( ) has a flange surface ( ) having a relief channel ( ) formed therein. A plurality of wheel studs ( ) are press fit into bolt opening ( ) formed in the relief channel ( ). This arrangement provides a flat flange surface ( ) for mating with a rotor ( ) to minimize brake run out. The knuckle hub assembly ( ) is mounted into a floating tool for finish turning of the flange surface ( ) to provide minimal run out and maximum flatness.

A part clamping fixture assembly for locating and holding a knuckle/hub assembly, including a knuckle, a wheel hub and a bearing, for final finishing of a flange face of the wheel hub includes a top portion, a first housing portion, and a second housing portion. The first housing portion is intended to engage a first appendage of the knuckle and the second housing portion is intended to engage a second appendage portion of the knuckle. The fixture assembly also includes a puller member having an upper end for communicating with a drive mechanism in order to rotate the knuckle/hub assembly and a lower end opposite the upper end. An encasing is disposed around the puller member and has a lower portion for contacting the bearing. The fixture assembly also includes a lift mechanism for lifting the knuckle/hub assembly generally upward such that a surface of the bearing engages the lower portion of the encasing and such that the first housing portion and the second housing portion engage the first and second appendages respectively.
