Drive pin assembly
View Patent ↗Provided are, among other things, systems, apparatuses, components and methods related to drive pin assemblies. One such assembly includes: a first pin component and a second pin component, each having an engagement end that opens to an interior space and has an angled surface that extends for at least a portion of the width and a portion of the length of such first pin component; and a tightening mechanism at least partially disposed within the interior spaces of the first pin component and the second pin component, for drawing the first pin component and the second pin component closer together, where the angled surface of the first pin component matches the angled surface of the second pin component such that the first pin component and the second pin component slide both vertically and laterally along each other when drawn together.
1. A drive pin assembly, comprising:
a first pin component having a width, a length, an outer end and an engagement end, the engagement end of the first pin component opening to an interior space and having an angled surface that extends for at least a portion of the width and a portion of the length of said first pin component; and
a second pin component having a width, a length, an outer end and an engagement end, the engagement end of the second pin component opening to an interior space and having an angled surface that extends for at least a portion of the width and a portion of the length of said second pin component;
a mounting component that includes an opening defined by a sidewall; and
a tightening mechanism at least partially disposed within the interior space of the first pin component and the interior space of the second pin component, for drawing the first pin component and the second pin component closer together,
wherein the engagement end of the first pin component contacts the engagement end of the second pin component within said opening in the mounting component,
wherein the angled surface of the first pin component matches the angled surface of the second pin component such that when the first pin component and the second pin component are drawn together, the first pin component and the second pin component slide both vertically and laterally along each other and outer side surfaces of the first pin component and the second pin component are pressed against the sidewall of the opening in the mounting component, and
wherein said mounting component is attached to at least one of a drive assembly and an axle assembly for a motorized vehicle.
2. A drive pin assembly according to claim 1 , further comprising a disc brake rotor having a mounting section that includes an opening, and wherein the outer end of the second pin component extends through the opening in the mounting section of the disc brake rotor.
3. A drive pin assembly according to claim 2 , wherein the second pin component includes a collar disposed on its outer surface at a distance from its outer end that is slightly greater than a thickness of the mounting section of the rotor in a vicinity of the opening in the mounting section.
4. A drive pin assembly according to claim 2 , wherein the outer end of the second pin component also includes an opening.
5. A drive pin assembly according to claim 4 , wherein the tightening mechanism comprises a bolt that extends into the opening in the outer end of the second pin component.
6. A drive pin assembly according to claim 5 , wherein the mounting section of the rotor is disposed between an enlarged head of the bolt and the collar.
7. A drive pin assembly according to claim 6 , wherein the opening in the disc brake rotor is just wide enough to accommodate the outer end of the second pin component in the circumferential dimension and is elongated in the radial direction, thereby accommodating radial expansion and contraction of the disc brake rotor when the outer end of the second pin component extends through the opening in the disc brake rotor and when the bolt fully tightened.
8. A drive pin assembly according to claim 1 , wherein the outer end of the second pin component also is open, and wherein an interior passageway extends from the outer end of the second pin component to the engagement end of the second pin component.
9. A drive pin assembly according to claim 8 , further comprising a bolt that extends through the passageway of the second pin component and into the opening in the engagement end of the first pin component.
10. A drive pin assembly according to claim 9 , wherein the bolt has an enlarged head at its proximal end, adjacent to the outer end of the second pin component, and has threads at its distal end, and wherein the interior space of the first pin component has internal threads that mate with the threads at the distal end of the bolt.
11. A drive pin assembly according to claim 1 , wherein the angled surfaces of the first pin component and the second pin component are substantially straight.
12. A drive pin assembly according to claim 11 , wherein the angled surface of the engagement end of the first pin component is disposed within a middle portion of the engagement end of the first pin component and outer portions of the engagement end of the first pin component are substantially flat and horizontal, and wherein the angled surface of the engagement end of the second pin component is disposed within a middle portion of the engagement end of the second pin component and outer portions of the engagement end of the second pin component are substantially flat and horizontal.
13. A drive pin assembly according to claim 1 , wherein the angled surfaces of the first pin component and the second pin component are laterally offset from each other.
14. A drive pin assembly according to claim 1 , wherein a combined assembly of the first pin component and the second pin component increases in width when the first pin component and the second pin component are drawn together.
