case portion 13
[0047]Case portion 13 includes an axial protrusion 80, which contacts an annular rim 82 on case portion 14, when the parts are assembled. The axial protrusion 80 is formed with a series of arcuate recesses 84, spaced angularly about axis 15. Each recess 84 partially surrounds a respective spider pin 28, 30, 32 (as shown in FIG. 6) and is aligned with a spider pin hole portion 86 formed in case portion 14. Each recess 84 and hole portion 86 complete a circular or slotted hole 88, which contains a spider pin 28, 30, 32 when the case is assembled.
[0048]FIGS. 3 and 4 illustrate an alternative embodiment of a differential assembly 62, in which two differential case portions 64, 66 are secured mutually and to a ring gear 67 by a series of bolts, each bolt being fitted into a hole 68 located on a circle of bolt holes formed in a radial flange 70 on case portion 64 and a hole 72 located on a circle of bolt holes formed in a radial flange 74 and aligned with a hole 68 on case portion 66. Fla...
case portion 64
[0050]Case portion 64 includes an annular, axial-extending protrusion 80, which contacts an annular rim 82 on case portion 66, when the parts are assembled, as shown in FIG. 4. The axial protrusion 80 is formed with a series of arcuate recesses 84, spaced angularly about axis 15. Each recess 84 partially surrounds its respective spider pin 28, 30, 32 and is aligned with a spider pin hole portion 86 formed in case portion 66. Each recess 84 and hole portion 86 complete a circular hole 88, which contains a spider pin 28, 30, 32 when the case is assembled as shown in FIG. 4.
[0051]FIG. 5 illustrates the pinions 22-25 supported on a case portion 14, 66 for rotation about the spider pins 28, 30, 32. FIG. 6 shows parallel slots 90 formed at diametrically opposite sides of spider pin 30, and parallel slots 92 formed at diametrically opposite sides of spider pin 32. A clip 94 includes legs 96, 97, each of which engages a slot 90 on spider pin 30, and legs 98, 99, each of which is similar res...
first embodiment
[0055]FIG. 10A shows the first embodiment, the open differential 10 of FIGS. 1-4, whose case portion 13 includes the annular, axial-extending protrusion 80.
