Abstract
A mounting system for a differential, comprising a cross shaft, a first stub shaft, a second stub shaft, and a yoke. The cross shaft comprises a long axis and a passageway through the cross shaft perpendicular to the long axis, the passageway comprising a first hole and a second hole. The first stub shaft comprises a long axis parallel to a central axis of the first hole. The second stub shaft comprises a long axis parallel to a central axis of the second hole. The yoke is in the passageway and comprises a first portion extending in to the first stub shaft and a second portion extending in to the second stub shaft.
Claims20
A mounting system for a differential, comprising:
- a cross shaft comprising:
- a long axis;
- and
- a passageway through the cross shaft perpendicular to the long axis, the passageway comprising a first hole and a second hole;
- a first stub shaft comprising a long axis parallel to a central axis of the first hole;
- a second stub shaft comprising a long axis parallel to a central axis of the second hole;
- and
- a yoke in the passageway comprising a first portion extending in to the first stub shaft and a second portion extending in to the second stub shaft.
The mounting system of claim 9, wherein the first recess comprises at least one planar side wall and an exterior portion of the first stub shaft is planar and is configured to abut the at least one planar side wall of the first recess, and wherein the second recess comprises at least one planar side wall and an exterior portion of the second stub shaft is planar and is configured to abut the at least one planar side wall of the second recess.
A differential comprising:
- a one piece housing for substantially enclosing:
- a first, second, third, and fourth pinion gear;
- a cross shaft passing through the first and second pinion gears;
- a first stub shaft passing through the third pinion gear;
- a second stub shaft passing through the fourth pinion gear;
- and
- a yoke passing through portions of the cross shaft, the first stub shaft, and the second stub shaft,
- wherein the yoke fits to the first stub shaft and the second stub shaft to retain the cross shaft, the first stub shaft, and the second stub shaft within the housing.
A method for assembling pinion shafts in a differential housing comprising the steps of:
- inserting a cross shaft in to a first opening in the housing and extending the cross shaft through the housing to a second opening in the housing;
- inserting a yoke in to a first stub shaft;
- inserting a second stub shaft in to a third opening in the housing;
- extending the second stub shaft in to abutment with the cross shaft;
- inserting the first stub shaft in to a fourth opening in the housing;
- extending the first stub shaft in to abutment with the cross shaft;
- passing the yoke through cross shaft openings;
- and
- fitting the yoke to the second stub shaft.
