Constrained multiple instantaneous velocity center linkage assembly for vehicle suspension

1. A structure for constraining locations of three instantaneous velocity centers (IVCs) in a two-wheel vehicle having a shock and a suspension linkage, the suspension linkage comprising:

a first body ( 3 );

a second body ( 6 );

a third body ( 4 ) operatively coupled with one another wherein:

the first body ( 3 ) includes a jointed connection with the second body ( 6 ) defining an IVC[3][6] ( 9 ), and a jointed connection to the third body ( 4 ) defining an IVC[3][4] ( 8 ),

the second body ( 6 ) is operatively coupled to the third body ( 4 ) defining an IVC[4][6] ( 10 ), wherein:

the first body ( 3 ) includes a first aperture, having a common axis with the IVC[3][4] ( 8 ),

the second body ( 6 ) includes a second aperture having a common axis of the IVC [3][6] ( 9 ),

the IVC[3][4]( 8 ), the IVC[3][6] ( 9 ) and the IVC[4][6] ( 10 ) are located within one of the first aperture or the second aperture, and

the IVC[3][4] ( 8 ), the IVC[3][6] ( 9 ), and the IVC[4][6] ( 10 ) are located in different positions from one another; and

the shock operably coupled with the suspension linkage to resist movement of at least one of the first body ( 3 ), the second body ( 6 ), or the third body ( 4 ).

2. The structure of claim 1 , wherein a size of the first aperture is different than a size of the second aperture.

3. The structure of claim 2 , wherein the size of the first aperture is larger than the size of the second aperture.

4. The structure of claim 2 , wherein the size of the second aperture is larger than the size of the first aperture.

5. The structure of claim 1 , wherein the first body ( 3 ) comprises two link bodies coupled to one another to form a single, rigid body.

6. The structure of claim 5 , wherein:

the two link bodies each include respective first circular interfaces that define a first axis when the two link bodies are coupled together by the respective first circular interfaces,

the two link bodies each include respective second circular interfaces that define a second axis offset from the first axis when the two bodies are coupled together by the respective first circular interfaces; and

a fastener is coupled to the respective second circular interfaces through the second axis such that the two link bodies are keyed together as a single rigid body.

7. The structure of claim 5 , wherein a first link body of the two link bodies includes a third aperture that defines the IVC[3][4] ( 8 ) and a second link body of the two link bodies includes a fourth aperture that defines the IVC[3][6] ( 9 ); wherein the second link body is keyed to the first link body to define a position of the IVC[3][4] ( 8 ) relative to the IVC[3][6] ( 9 ).

8. The structure of claim 1 , wherein the first body ( 3 ) comprises a slotted portion defining a pair of deformable opposing jaws.

9. The structure of claim 8 , wherein the opposing deformable jaws are configured to grip a shaft of a bearing.

10. The structure of claim 1 , wherein one of the first body ( 3 ), the second body ( 6 ), or the third body ( 4 ) is a chain stay.

11. The structure of claim 1 , wherein one of the first body ( 3 ), the second body ( 6 ), or the third body ( 4 ) is a suspended body.
