Quick change adjustable track center front hub assembly and method of use

A front hub assembly for use on a spindle axle of a sprint car for providing quick-change and adjustable track center of a front wheel, comprising:

• a hub having an inboard end and an outboard end and an external surface and an internal surface, said external surface having external splines that run substantially parallel to the major axis of said hub, said external splines located between said inboard end and said outboard end of said hub;
• at least two bearings spaced apart from each other by a distance, each of said at least two bearings having an inner race and an outer race, said inner race securingly contacting said spindle axle and said outer race securingly contacting said internal surface of said hub;
• at least one spacer located between said inboard end and said outboard end of said hub having internal splines for mating with said external splines of said external surface of said hub;
• a cap screw for connecting to said outboard end of said spindle axle for securing said at least two bearings to said spindle axle;
• and
• a lug nut for connecting to said outboard end of said hub for securing said at least one spacers to said front hub assembly.

A method for increasing the track center and providing quick-change of a front wheel mounted on a front hub assembly of a sprint car, said front hub assembly including a hub having an inboard end and an outboard end and an external surface, said external surface having external splines that run substantially parallel to the major axis of said hub, said external splines located between said inboard end and said outboard end of said hub;

• a wheel center section located between said inboard end and said outboard end of said hub, said wheel center section having internal splines for mating with said external splines of said external surface of said hub, said wheel center section having a rim halve attached to each side of said wheel center section;
• at least one spacer located between said wheel center section and said outboard end of said hub having internal splines for mating with said external splines of said external surface of said hub;
• a lug nut for connecting to said outboard end of said hub for securing said at least one spacer and said wheel center section to said front hub assembly, said method comprising:
• removing said lug nut from said outboard end of said hub;
• removing said at least one spacer from said hub;
• removing said wheel center section from said hub;
• positioning said at least one spacer onto said hub;
• positioning said wheel center section onto said hub;
• and
• securing said wheel center section and said at least one spacer to said front hub assembly by tightening said lug nut onto said outboard end of said hub.

A method for decreasing the track center and providing quick-change of a front wheel mounted on a front hub assembly of a sprint car, said front hub assembly including a hub having an inboard end and an outboard end and an external surface, said external surface having external splines that run substantially parallel to the major axis of said hub, said external splines located between said inboard end and said outboard end of said hub;

• a wheel center section located between said inboard end and said outboard end of said hub, said wheel center section having internal splines for mating with said external splines of said external surface of said hub, said wheel center section having a rim halve attached to each side of said wheel center section;
• at least one spacer located between said wheel center section and said inboard end of said hub having internal splines for mating with said external splines of said external surface of said hub;
• a lug nut for connecting to said outboard end of said hub for securing said at least one spacer and said wheel center section to said front hub assembly, said method comprising:
• removing said lug nut from said outboard end of said hub;
• removing said wheel center section from said hub;
• removing said at least one spacer from said hub;
• positioning said wheel center section onto said hub;
• positioning said at least one onto said hub;
• and
• securing said wheel center section and said at least one spacer to said front hub assembly by tightening said lug nut onto said outboard end of said hub.

A process for manufacturing a front hub assembly comprising:

• providing a hub having an inboard end and an outboard end and an external surface and an internal surface, said external surface having external splines that run substantially parallel to the major axis of said hub, said external splines located between said inboard end and said outboard end of said hub;
• positioning at least one outboard bearing inside of said hub against said internal surface towards said outboard end of said hub;
• positioning an axle spacer inside of said hub between said at least one outboard bearing and said inboard end of said hub;
• and
• positioning at least one inboard bearing inside of said hub between said axle spacer and said inboard end of said hub;
• and
• securing said at least one inboard bearing and said at least one outboard bearing to said hub.
