Abstract
A modified differential internal system for a vehicle differential may include a preexisting ring gear having a perimeter. The system may include a ring gear sleeve having a thickness, the ring gear sleeve being affixed to the ring gear perimeter. The system may include a spring retainer having a first surface and a second surface, the first surface having a first set of lugs and the second surface having a second set of lugs. The system may include an armature plate having a plurality of slots configured to engage the first set of lugs, and a sprag plate having a plurality of slots configured to engage the second set of lugs. The sprag plate may have a plurality of locking tabs configured to engage a sprag cage of the vehicle differential.
Claims19
A modified internals system for a vehicle differential, the system comprising:
- a preexisting ring gear having a perimeter;
- a ring gear sleeve having a thickness, the ring gear sleeve being affixed to the ring gear perimeter;
- a spring retainer having a first surface and a second surface, the first surface having a first set of lugs and the second surface having a second set of lugs;
- an armature plate having a plurality of slots configured to engage the first set of lugs;
- and
- a sprag plate having a plurality of slots configured to engage the second set of lugs, the sprag plate having a plurality of locking tabs configured to engage a sprag cage of the vehicle differential.
A method of modifying internals of a vehicle differential, the method comprising the steps of:
- welding a ring gear sleeve having a thickness to a perimeter of a preexisting ring gear;
- providing a spring retainer, the spring retainer having a first surface and a second surface, the first surface having a first set of lugs and the second surface having a second set of lugs;
- machining an armature plate, the armature plate having a plurality of slots configured to engage the first set of lugs;
- machining a sprag plate, the sprag plate having a plurality of slots configured to engage the second set of lugs and having a plurality of locking tabs configured to engage a sprag cage of the vehicle differential;
- and
- assembling each of the ring gear, the spring retainer, the armature plate, and the sprag plate within the vehicle differential.
A modified internals system for a vehicle differential, the system comprising:
- a ring gear having a cylindrical wall and a perimeter, the cylindrical wall having a first thickness;
- a ring gear sleeve having a second thickness, the ring gear sleeve being welded to the ring gear perimeter;
- a spring retainer having a first surface and a second surface extending perpendicularly from the first surface, the first surface having a first set of lugs extending in a direction, and the second surface having a second set of lugs extending in the direction;
- an armature plate having a plurality of slots configured to engage the first set of lugs and an inner perimeter configured to fit around the ring gear sleeve;
- a sprag cage having rollers;
- and
- a sprag plate having a plurality of slots configured to engage the second set of lugs, the sprag plate having a plurality of locking tabs configured to engage the sprag cage.
