Abstract
Some examples of a cable cutting system include a first cutting apparatus that includes a recess to receive a cable. The system includes a second cutting apparatus separate from and attached to the first cutting apparatus. The second cutting apparatus includes multiple cutting surfaces arranged to cut the cable received at the recess.
Claims23
A cable cutting system for a vehicle comprising:
- a first cutting apparatus comprising a recess to receive a cable and a first cutting surface positioned in the recess, wherein the recess is disposed between a first guiding surface and a second guiding surface, and the first guiding surface is affixed to a surface of the vehicle;
- a second cutting apparatus separate from and attached to the first cutting apparatus at a pivot position located proximate to the recess and the second guiding surface of the first cutting apparatus, the second cutting apparatus comprising a cutter wheel having a plurality of second cutting surfaces forming a plurality of cutting teeth having a space between adjacent cutting teeth to receive the cable, the plurality of teeth arranged about the cutter wheel to cut the cable received in the space between the adjacent teeth, wherein the space between the adjacent cutting teeth is larger than the recess;
- and
- wherein the pivot position is located behind a position in the recess that provides a minimum clearance between the plurality of first cutting surfaces in the recess and the cable, and the cutter wheel is configured to rotate around the pivot position in response to the cable contacting the cutter wheel such that the second cutting surface contacting the cable forces the cable into contact with the first cutting surface of the first cutting apparatus, and both the first cutting surface and the second cutting surface cut the cable received in the space.

A cable cutting system for a vehicle comprising:
- a first cutting apparatus comprising:
- a recess to receive a cable, and
- a first cutting surface positioned in the recess,
- wherein the recess is disposed between a first guiding surface and a second guiding surface, and the first guiding surface is affixed to a surface of the vehicle;
- a second cutting apparatus separate from and attached to the first cutting apparatus at a pivot position located above the recess of the first cutting apparatus, the second cutting apparatus comprising a cutter wheel having a plurality of second cutting surfaces forming five or more pointed cutting teeth arranged equidistantly having a space between adjacent cutting teeth to receive the cable, the plurality of teeth arranged about the cutter wheel to cut the cable received in the space between the adjacent cutting teeth, wherein the space between the adjacent cutting teeth is larger than the recess;
- and
- wherein the cutter wheel is configured to rotate around the pivot position in response to the cable contacting the cutter wheel such that the second cutting surface contacting the cable forces the cable downward into contact with the first cutting surface, and both the first cutting surface and the second cutting surface cut the cable received in the space, the pivot position being located behind a position in the recess that provides a minimum clearance between the first cutting surface in the recess and the cable, wherein a cutting force exerted by the cutting teeth of the cutter wheel on the cable increases as an angle between the cutting force and a vertical line passing through the pivot position decreases.
