Claims
- 1. A spud, comprising:
- a body portion centered about a first axis, said body portion having inner and outer walls, said outer wall including a first plurality of threads; and, a holding member extending radially outwardly from said body portion
- wherein the radial distance of said holding member from said first axis is at least 1.15 times the radial distance of said first plurality of threads of said outer wall of said body portion from said first axis.
- 2. The spud of claim 1 wherein said inner wall defines a circular bore and includes a second plurality of threads.
- 3. The spud of claim 1 wherein said outer wall includes a pair of diametrically opposed flats.
- 4. The spud of claim 1 wherein said holding member comprises a circular flange.
- 5. A spud assembly, comprising:
- a spud having a body portion centered about a first axis, said body portion configured to extend through a first aperture in a fixed member and having an outer wall including a first pair of a diametrically opposed flats, the spud further comprising a holding member extending radially outwardly from said body portion, said holding member adjacent a surface of said fixed member and configured to prevent said spud from moving in a first axial direction relative to said fixed member;
- a washer disposed about said spud, an inner periphery of said washer including a second pair of diametrically opposed flats corresponding to said first pair of diametrically opposed flats;
- wherein said washer is fixed against rotation relative to said fixed member to thereby restrict rotational movement of said spud.
- 6. The assembly of claim 5, further comprising means for restricting axial movement of said spud relative to said fixed member.
- 7. The assembly of claim 6 wherein said restricting means comprises a nut threaded onto one end of said spud.
- 8. The assembly of claim 5 wherein said outer wall of said spud includes a plurality of threads.
- 9. The assembly of claim 8 wherein the radial distance of said holding member from said first axis is at least 1.15 times the radial distance of said plurality of threads of said outer wall of said body portion from said first axis.
- 10. The assembly of claim 5 wherein the radial distance of said holding member from said first axis is at least 1.15 times the radial distance of said first aperture.
- 11. The assembly of claim 5 wherein said washer includes a tang configured to be inserted through a second aperture in said fixed member.
- 12. The assembly of claim 5 wherein said washer includes a land having a second aperture, said second aperture configured to align with a third aperture in said fixed member and to receive a fastener that extends through said second and third apertures.
- 13. A friction assembly, comprising:
- a hub extending along a first axis;
- a holding plate extending radially outwardly of said first axis and fixed to said hub, said holding plate having a first aperture extending therethrough;
- a pressure plate axially spaced from said holding plate;
- friction discs disposed on a first side of said pressure plate;
- a bladder disposed between said holding plate and a second side of said pressure plate;
- a spud connected to said bladder through which said bladder may be selectively expanded and contracted to cause axial movement in said pressure plate and selective engagement and disengagement of said pressure plate with said friction discs, said spud having a body portion that extends through said first aperture in said holding plate and includes an outer wall having a first pair of diametrically opposed flats, the spud further comprising a holding member extending radially outwardly from said body portion, said holding member adjacent a surface of said holding plate and configured to prevent said spud from moving in a first axial direction relative to said fixed member;
- a washer disposed about said spud, an inner periphery of said washer including a second pair of diametrically opposed flats corresponding to said first pair of diametrically opposed flats;
- wherein said washer is fixed against rotational movement relative to said holding plate to thereby restrict rotational movement of said spud.
- 14. The assembly of claim 13, further comprising means for restricting axial movement of said spud relative to said fixed member.
- 15. The assembly of claim 14 wherein said restricting means comprises a nut threaded onto one end of said spud.
- 16. The assembly of claim 13 wherein said outer wall of said spud includes a plurality of threads.
- 17. The assembly of claim 13 wherein first axis is at least 1.15 times as the radial distance of said body portion from said first axis.
- 18. The assembly of claim 13 wherein the radial distance of said holding member from said first axis is at least 1.15 times the radial distance of said first aperture.
- 19. The assembly of claim 13 wherein said washer includes a tang configured to be inserted through a second aperture in said fixed member.
- 20. The assembly of claim 13 wherein said fixed member includes a second aperture and said washer includes a land having a third aperture, said second and third apertures configured to receive a fastener inserted through said second and third apertures.
