Definitions
- the present disclosure relates generally to differentials for use in automotive drivelines and, more particularly, to a method and an apparatus for retaining a cross pin within a differential housing.
- Many automotive drive axle assemblies include a hypoid gearset and a differential for changing the direction of power transmission from an axis parallel to the direction of vehicle travel to an axis perpendicular thereto.
- the hypoid gearset typically includes a ring gear coupled to a differential housing which is meshed with a pinion gear rotatably supported within the axle housing.
- the differential is rotatably mounted on a pair of differential bearings.
- the differential in most automotive drive axle assemblies includes a gearset which is supported within the differential housing to facilitate relative rotation between a pair of axle shafts.
- the differential gearset typically includes a pair of side gears that are coupled to the ends of axle shafts.
- the side gears are meshed with at least one set of pinions rotatably supported on a cross pin that is coupled to the differential housing.
- Various methods are known for securing the cross pin to the differential housing.
- at least one known differential uses a threaded fastener, such as a lock screw or bolt, to secure the cross pin to the differential housing.
- the threaded fastener extends through an aperture in the differential cross pin and is threadingly engaged with a hole in the differential housing.
- a roll-pin may be inserted between aligned holes in the differential housing and the cross pin to provide a non-threaded retention mechanism.
- Another known method of securing the differential cross pin includes positioning a snap ring within a groove formed in the cross pin and a corresponding groove formed in the differential housing.
- cross pin retention mechanisms may require costly machining operations to be performed on the differential housing, the cross pin or both. Furthermore, a costly and time-consuming torquing operation may be required when using a threaded fastener. Additionally, these retention methods may not permit convenient removal of the cross pin during assembly of the differential or axle assembly. Elimination of the torquing process or lock ring assembly steps may also be beneficial in reducing the time and cost required to manufacture the differential. In addition, the ability to conveniently remove the cross pin during the assembly process may be beneficial to reduce the time and cost required to interconnect the axle shafts to the side gears of the differential.
- the present disclosure provides an arrangement for securely retaining the cross pin within the housing of a differential assembly.
- the improved arrangement for retaining the cross pin includes the use of a cross pin retainer which permits relatively simple and rapid assembly of the differential assembly.
- the cross pin retainer is positionable at a first or partially-inserted position to temporarily retain the cross pin within the differential housing and to permit easy removal of the cross pin retainer and cross pin during assembly of the axle assembly. When located in its partially-inserted position, a portion of the cross pin retainer elastically deforms and snugly engages a retention bore formed in the differential housing.
- the cross pin retainer is also positionable at a second or fully- inserted position to permit retention of the cross pin within the differential housing.
- the cross pin retainer When located in its fully-inserted position, a portion of the cross pin retainer expands to engage a wall in the differential housing to restrict subsequent retraction of the cross pin retainer. Additionally, the cross pin retainer and the differential housing include surfaces that cooperate to facilitate the partial and full insertion of the cross pin retainer into the differential assembly. [0008]
- the present disclosure eliminates the need for costly machining operations previously required to provide an annular grove or throughbore in the differential housing.
- the present disclosure also provides for increased case strength by permitting use of smaller bore sizes in the differential housing.
- the present disclosure provides a method which may reduce the cost of a differential assembly by providing simpler manufacturing methods. Accordingly, costs are further minimized by reducing the time required to assemble the differential assembly and install the various components of an axle assembly.

- Figure 17 is a sectional side view of the cross pin retainer shown in Figure 16.
- Cross pin retention system 10 is shown operatively associated with an exemplary drive axle assembly 12.
- Drive axle assembly 12 includes an axle housing 14 for rotatably supporting a hypoid gearset including a pinion gear 16 and a ring gear 18 which is secured to a differential assembly 20.
- Differential assembly 20 functions to transfer power from pinion gear 16 to a pair of axle shafts 22 and 23 while compensating for any difference in axle shaft rotary speeds as may occur during a turn or other steering maneuver.
- differential assembly 20 In order to compensate for differences in the axle shaft rotary speeds, differential assembly 20 includes a pair of pinion gears 24 and a pair of side gears 26 which are drivingly interconnected to axle shafts 22 and 23.
- differential assembly 20 is rotatably mounted in axle housing 14 by a pair of differential bearings 28. More particularly, housing 14 includes two semi-circular journals (not shown) for supporting approximately one-half of the circumferences of each differential bearing 28.
- a pair of bearing caps 30 generally supports the remaining approximate one-half of each differential bearing 28.
- Each bearing cap 30 is mounted to axle housing 14 in a manner conventional in the art such as via threaded fasteners.
- differential assembly 20 includes a differential case or housing 32, a cross pin 34, a pair of side gear washers 36 and a pair of pinion gear washers 38 in addition to pinion gears 24 and side gears 26 previously introduced.
- Differential housing 32 includes an interior cavity 40 defined by a wall 42.
- Differential housing 32 includes a pair of axially aligned openings 44 extending through wall 42 and which interconnect interior cavity 40 with an external surface 46 of differential housing 32. Openings 44 are sized to rotatably support side gears 26. Openings 44 also allow axle shafts 22 and 23 to be inserted within interior cavity 40 and engage internal splines 48 on side gears 26.
- Differential housing 32 also includes a first aperture 50 and a second aperture 52 that are axially aligned with one another. Each of first and second apertures 50 and 52 extends through wall 42 to interconnect interior cavity 40 with external surface 46 of differential housing 32.
- a first housing bore 56 extends through wall 42 from external surface 46 to intersect first aperture 50.
- a second housing bore 60 extends through wall 42 from external surface 46 to intersect second aperture 52.
- Cross pin 34 is a generally cylindrically-shaped member having a first end 62 and a second end 64.
- First end 62 includes a first cross pin bore 66 while second end 64 includes a second cross pin bore 68.
- a pair of flats 70 ( Figure 2) are formed on cross pin 34 to function as lubricant reservoirs during operation.
- Cross pin 34 is positioned within first and second apertures 50 and 52 such that first cross pin bore 66 is aligned with first housing bore 56.
- second end 64 of cross pin 34 is positioned within second aperture 52 to align second cross pin bore 68 with second housing bore 60.
- Pinion gears 24 are rotatably supported on cross pin 34.
- Pinion gear washers 38 are positioned within interior cavity 40 between wall 42 and pinion gears 24. Each pinion gear washers 38 provides a thrust surface against which the pinion gears may bear.
- side gear washers 36 are positioned between side gears 26 and differential housing 32.
- cross pin 34 is shown to be retained within differential housing 32 by a cross pin retainer 100.
- cross pin retainer 100 is positioned within aligned bores 56 and 66.
- a second cross pin retainer 100 may be positioned in aligned bores 60 and 68 to provide additional retention of cross pin 34.
- Cross pin retainer 100 is formed of a semi-compliant material (i.e., a polymer, nylon, plastic, etc.) having substantially lower mechanical properties than differential assembly 32 and cross pin 34.
- cross pin retainer 100 has a body 102, a first end 104 and a second end 106.
- Body 102 is cylindrically- shaped and adapted to support cross pin retainer 100 within differential housing bore 56.
- First end 104 may be rectangular in shape and has a pair of opposing face surfaces 108 and 1 10 and an index surface 1 12. Opposing face surfaces 108 and 1 10 are adapted to allow cross pin retainer 100 to be grasped and positioned.
- Index surface 1 12 is adapted to engage a first wall surface 114 of differential housing 32 when cross pin retainer 100 is positioned in its partially- inserted position at a first rotational orientation, as shown in Figure 8.
- Index surface112 is also adapted to engage a second wall surface 116 of differential housing 32 when cross pin retainer 100 is positioned in its fully-inserted position at a second rotational orientation, as shown in Figure 1 1.
- Second end 106 is generally conically-shaped to facilitate the insertion of cross pin retainer 100 within housing bore 56 and includes a slot 1 18 and a retention surface 120.
- second end 106 may have, but not limited to, an elliptical base with a minor diameter 124 and a major diameter 126. Minor diameter 124 is substantially equal to the diameter of differential housing bore 56 and is adapted to allow cross pin retainer 100 to be inserted within housing bore 56.
- Major diameter 126 is greater than the diameter of bore 56 to permit retention of cross pin retainer 100 within differential housing 32 when located in its fully-inserted position.
- Slot 1 18 is oriented perpendicular to the axis of major diameter 126 and extends from second end 106 partially into body 102. Slot 1 18 is dimensioned such that second end 106 may be sufficiently compressed (see Figure 9) to allow second end 106 to be positioned within differential housing bore 56.
- Retention surface 120 is adapted to engage a wall 122 defining first aperture 50 when cross pin retainer 100 is located in its full- inserted position.
- cross pin retainer 100 may be positioned at a fully-inserted position and at a partially-inserted position to retain cross pin 34. It may be particularly desirable to locate cross pin retainer 100 at the partially-inserted position to permit partial extraction of cross pin retainer 100 and subsequent removal of cross pin 34 during the assembly of drive axle assembly 12. Accordingly, cross pin retainer 100 may be positioned within housing bore 56 at its partially-inserted position by grasping and positioning first end 104 at the first rotational position with respect to differential housing 32, inserting second end 106 within differential housing bore 56 and translating cross pin retainer 100 toward first aperture 50 until index surface 112 engages first wall surface 1 14 of differential housing 32.
- cross pin retainer 100 When cross pin retainer 100 is located in its partially-inserted position, a portion of second end 106 extends into aperture 50 to provide retention of cross pin 34, yet cross pin retainer 100 may be easily retracted from housing bore 56. [0039] Cross pin retainer 100 may then be positioned within housing bore 56 to a fully-inserted position by grasping and rotating first end 104 to its second rotational position with respect to differential housing 32 and further translating cross pin retainer 100 toward first aperture 50 until index surface 1 12 engages second wall surface 1 16 of differential housing 32. When cross pin retainer 100 is in its fully-inserted position, second end 106 is positioned within aperture 50 such that retention surface 120 engages wall 122 formed by aperture 50, thereby securing cross pin retainer 100 within differential housing 32.
- first end 104 is positioned within a channel (see Figure 3) having a bottom formed by second wall surface 1 16 and sides formed by a wall 128.
- Wall 128 provides a clearance between first end 104 and differential housing 32 at the second rotational orientation, but substantially limits rotation of first end 104 when cross pin retainer 100 is located in its fully-inserted position.
- a second cross pin retainer 100 may be positioned within bores 60 and 68 in a manner similar to that just described.
- differential assembly 20 is serviceable should the need arise. Because cross pin retainer 100 exhibits substantially lower mechanical properties than cross pin 34 or differential housing 32, differential assembly 20 may be disassembled by shearing cross pin retainer 100 by driving cross pin 34 along its longitudinal axis.
- differential assembly 20 may be serviced and reassembled by positioning either one or two new cross pin retainers 100 within differential housing 32 in the manner previously described. Removal of cross pin retainer 100 may also be facilitated by heating differential housing 32 and cross pin 34 to a sufficient temperature to cause cross pin 100 to melt and then driving cross pin 34 along its longitudinal axis.
- a cross pin retainer 200 includes a retention member 202 in slidable receipt of a support pin 204, a first end 206, and a second end 208.
- Retention member 202 includes a body 210 having a throughbore 212 in receipt of pin 204. Bore 212 is coaxially aligned with body 210 and extends through first end 206 and body 210 to permit the insertion of support pin 204 into body 210.
- Support pin 204 has a shaft 216 and a head 218. Shaft 216 is cylindrical and is adapted to fit snugly in bore 212.
- Head 218 is larger than bore 212 and has a face surface 220 adapted to engage a face surface 222 of first end 206 when support pin 204 is positioned at a fully-inserted position.
- support pin 204 is formed of a material with mechanical properties greater than those of retention member 202, but substantially lower than differential housing 32.
- Cross pin retainer 200 may be positioned at a partially-inserted position as shown in Figures 12 and 13, as well as at a fully-inserted position as shown in Figures 10 and 1 1.
- Retention member 202 includes a graspable tab 224 shaped similarly to first end 104 of cross pin retainer 100.
- Tab 224 operates in a manner substantially similar to first end 104, as previously described for cross pin retainer 100.
- Support pin 204 is moveable between a first position shown in Figures 12 and 13 and a second position shown in Figures 10 and 1 1. Support pin 204 is located in its first position during location of cross pin retainer 200 in its partially-inserted position.
- retention member 202 is displaced toward the fully-inserted position while support pin 204 remains in its first position.
- Second end 208 is allowed to collapse a slot 226 formed in retention member 202.
- body 210 returns to its undeformed shape and a retention surface 228 engages wall surface 122.
- an operator axially displaces support pin 204 from the first position to the second position.
- Support pin 204 is translated through throughbore 212 and aperture 50 until face surface 220 is seatingly engaged with face surface 222.
- support pin 204 is positioned within a blind bore 230 in differential housing 32.
- Blind bore 230 is adapted to receive support pin 204.
- support pin 204 provides additional structural support for cross pin 34 and retention member 202.
- support pin 204 may have a shaft which is shorter than shown and which may extend through body 210 to second end 208, but does not extend into blind bore 230.
- support pin 204 may be molded into retention member 202 to form a composite cross pin retainer according the teachings of the present disclosure.
- support pin 204 may be subassembled to retention member 202 to facilitate the partial and full insertion of cross pin retainer 200 in differential housing 32.
- a cross pin retainer 300 comprises a retention member 302 and a support pin 304.
- Support pin 304 is substantially similar to support pin 204 of cross pin retainer 200.
- Retention member 302 further comprises a body 306, a first end 308 and a second end 310.
- First end 308 and second end 310 are substantially similar to first end 206 and second end 208 of cross pin retainer 200.
- Body 306 includes annular fins 312 that are adapted to elastically deform as cross pin retainer 300 is positioned in bore 56 to a partially-inserted position as previously described. To this end, body 306 has a minor diameter 314 that is sufficiently smaller than the diameter of bore 56 to allow annular fins 312 to elastically deform while positioned within bore 56.
- Annular fins 312 include a retention surface 316 which is adapted to engage wall 122 of aperture 50 when cross pin retainer 300 is positioned in its fully-inserted position, as previously described. Once annular fins 312 are positioned within aperture 50, annular fins 312 expand to cause retention surface 316 to engage wall surface 122.
- a cross pin retainer 400 is shown to include retention member 402 and a support pin 404.
- Support pin 404 is substantially similar to support pin 204 of cross pin retainer 200.
- Retention member 402 further comprises a body 406, a first end 408 and a second end 410.
- First end 408 is substantially similar to first end 206 of cross pin retainer 200.
- Cross pin retainer 400 further comprises an aperture 412 extending through body 406 and second end 410.
- Aperture 412 is sized to allow a portion of body 406 and second end 410 to elastically deform as cross pin retainer 400 is positioned in bore 56 to a partially-inserted position as previously described.
- aperture 412 has a height 414 that is sufficient to allow a portion of body 406 and second end 410 to elastically deform while positioned within bore 56.
- Second end 410 includes a retention surface 416 which engages wall surface 122 of aperture 50 when cross pin retainer 400 is positioned in its fully- inserted position as previously described.
