Reciprocating rail movement suspension system
Generally, examples described herein may take the form of a bicycle including a front frame, a rear frame operably associated with the front frame and configured for coupling to a rear wheel, and a suspension system operably associated with the front frame and the rear frame. The suspension system includes a first connection structure operably coupling the front frame to the rear frame and a first sliding body pivotally coupled to the rear frame and configured to travel in a first direction along a substantially linear travel path and in a second direction opposite the first direction along the substantially linear travel path as the suspension system is compressed.
1. A bicycle comprising:
a first frame
operably associated with a second frame, wherein at least one of the frames is configured for coupling to a rear wheel; and
a suspension system operably associated with each of the frames, the suspension system comprising:
a first connection structure operably coupling each of the frames together; and
a first sliding body pivotally coupled to at least one of the frames and configured to travel in both a first direction along a substantially linear travel path and a second direction opposite the first direction along the substantially linear travel path, wherein both the first direction and the second direction are traveled as the suspension system is compressed.
2. The bicycle of claim 1 , wherein the first sliding body is configured to engage a first rail.
3. The bicycle of claim 1 , wherein the bicycle further comprises a shock assembly pivotally coupled to the first frame at a first end, wherein the first frame is a front frame of the bicycle.
4. The bicycle of claim 2 , wherein the first rail is coupled to at least one of the frames.
5. The bicycle of claim 1 , wherein the first sliding body is configured to travel in the second direction along the substantially linear travel path and in the first direction opposite the second direction along the substantially linear travel path as the suspension system is extended.
6. The bicycle of claim 1 , wherein the second frame is a rear frame that comprises:
a forward member having a top end and a bottom end;
a chain stay that extends rearwardly from the bottom end of the forward member to a rear portion; and
a seat stay that extends rearwardly from the top end of the forward member to the rear portion;
wherein a top end of the forward member is pivotally coupled to the first connection structure.
7. The bicycle of claim 6 , wherein a bottom end of the forward member is pivotally coupled to the first sliding body.
8. The bicycle of claim 6 , wherein first connection structure comprises a link and the top end of the forward member is configured to travel along an arcuate path defined by the link.
9. The bicycle of claim 2 , wherein the first sliding body is configured to switch directions at an inflection point of a path traveled by the rear wheel.
10. The bicycle of claim 2 , wherein the first sliding body is further configured to engage a second rail that is substantially parallel to the first rail.
11. The bicycle of claim 10 , wherein the first and second rails together define a plane that is substantially parallel to a plane defined by the first frame which is a front frame of the bicycle.
12. The bicycle of claim 10 , wherein the first and second rails are joined to a mount that is joined to the first frame.
13. The bicycle of claim 12 , wherein the mount has a truncated C shape or a rectangular shape.
14. The bicycle of claim 1 , wherein a vertical component of the substantially linear travel path of the first sliding body is larger than a horizontal component of the substantially linear travel path of the first sliding body.
15. The bicycle claim 1 , wherein the first frame is a front frame and the second frame is a rear frame.
16. The bicycle of claim 1 , wherein a horizontal component of the substantially linear travel path of the first sliding body is larger than a vertical component of the substantially linear travel path of the first sliding body.
17. The bicycle of claim 1 , wherein a horizontal component of the substantially linear travel path of the first sliding body is the same as a vertical component of the substantially linear travel path of the first sliding body.
