Definitions
- the present invention relates generally to cables and methods for manufacturing cables. More particularly, the present invention relates to push- pull cables and methods of manufacturing push-pull cables.
- Push-pull cables are commonly included in automatic transmission shifters, mechanical latches, hydraulic valve control operations and many other currently-available devices.
- a typical push-pull cable such as an automatic transmission shift cable, allows for back and forth movements of one or more components inside of a casing.
- FIG. 1 is a cross-sectional view illustrating the central portion of a push-pull cable according to the prior art. More specifically, FIG. 1 illustrates the central portion or core of a 1x13 push-pull cable according to the prior art. As illustrated in FIG. 1, a central wire 2 is surrounded by twelve peripheral wires 4. The peripheral wires 4, in turn, are surrounded by a flat wrap 6. Also, the flat wrap 6 is surround by an outer-coating 8.
- FIG. 1 Other components, which are not illustrated in FIG. 1 , are arranged about the outer-coating 8 to make up the rest of the push-pull cable.
- the push-pull cable itself is capable of supporting both a tensile load and a compressive load.
- FIG. 1 The components illustrated in FIG. 1 are commonly found in 40- series push-pull cables, which have standardized dimensions that are easily obtainable by those of skill in the art. Within those dimensions, a 40-series cable can be designed to support a certain range of loads in tension and in compression for a range of distances of travel. However, what is needed are alternate push- pull cables that can support additional loads, both in tension and in compression, and which can withstand cyclic loading for a larger number of cycles under high loads.
- a push-pull cable capable of providing a reliable interface between two mechanical objects to provide both tensile and compressive linking.
- the cable includes a central wire capable of supporting both a tensile load and a compressive load.
- the cable also includes a first set of wires that are wrapped around the central wire.
- the cable further includes a second set of wires that are wrapped around the first set of wires. Also, in the cable, wires in the first set of wires are in contact with wires in the second set of wires.
- a method of manufacturing a push-pull cable capable of providing a reliable interface between two mechanical objects to provide both tensile and compressive linking includes wrapping a first set of wires around a central wire, wherein the central wire is capable of supporting both a tensile load and a compressive load.
- the method also includes wrapping a second set of wires around the first set of wires, wherein the second set of wires is in contact with the first set of wires.
- the cable includes a first supporting means for supporting both a tensile load and a compressive load.
- the cable also includes a second supporting means for further supporting the tensile load and the compressive load, wherein the second supporting means is wrapped around the first supporting means.
- the cable further includes a third supporting means for even further supporting the tensile load and the compressive load, wherein the third supporting means is in contact with and wrapped around the second supporting means.
- FIG. 1 is a cross-sectional view illustrating the central portion of a push-pull cable according to the prior art
- FIG. 2 is a cross-sectional view of the central portion of a push- pull cable according to certain embodiments of the present invention
- FIG. 3 is a side view of a cut-away section of the push-pull cable illustrated in FIG. 2;

- first set of wires 12 are illustrated as forming the first set of wires 12 in FIG. 2, no particular restrictions are placed on the number of wires that may be included in the first set of wires 12. For example, according to certain embodiments, between 8 and 16 wires can be used while between 9 and 15 wires can be used according to certain other embodiments.
- the wires in the first set of wires 12 may be made from any material (e.g., metals, ceramics, polymers), the wires in the first set of wires 12 are often made of steel (e.g., aircraft quality galvanized steel such as AISI 1065). An approximate diameter of 0.019 inches is typically chosen for each of the wires in the first set of wires 12 when manufacturing a 40-series push-pull cable.
- wires of many other geometries are also within the scope of the present disclosure.

- the wires in the first set of wires 12 are typically wrapped in a helix around the central wire 10. This configuration is further illustrated in FIG. 3, which offers a side view of a cut-away section of the push-pull cable illustrated in FIG. 2. As shown in FIG. 3, the wires in the set of wires 12 are generally wrapped in either a right- or left-handed direction. However, the wires maybe wrapped in alternate manners or, according to certain embodiments, may even be positioned parallel to the central wire 10.

- intermediate components may be positioned between the wires in the first set of wires 12 and the second set of wires 14.
- the second set of wires 14 may be wrapped in a second direction that is different from the first direction (e.g., a left-handed direction).
- first direction e.g., a right-handed direction
- second direction e.g., a left-handed direction
- push-pull cables wherein the first set of wires 12 and the second set of wires 14 are wrapped in the same or substantially the same direction are also within the scope of the present invention.
- FIG. 2 eighteen wires are illustrated as being included in the second set of wires 14. However, no particular restrictions are placed on the number of wires that may be included in the second set of wires 14 according to the present invention. For example, according to certain embodiment, between

Also, although the coating 16 is illustrated in FIG. 2 as being in direct contact with the second set of wires 14, intermediate components may be included between the second set of wires 14 and the coating 16.
- the coating 16 is often chosen to have an outer diameter of approximately 3/16".
- splines 17 may be formed on the outside of coating 16. Splines 17 may be used, for example, to more easily position the components illustrated in FIG.2 within a push-pull cable.
- a first supporting means for supporting both a tensile load and a compressive load are included in the cable.
- the first supporting means can take the form of, for example, the central wire 10 in FIG. 2.
- a second supporting means for further supporting the tensile load and the compressive load is then typically wrapped around the first supporting means.
- An example of such second supporting means is exemplified as the first set of wires 12 in FIG. 2.
- the second supporting means includes about 12 wires, ⁇ 4 wires.
- configurations with additional or fewer wires are also within the scope of the present invention.

- Steps 20 and 22 may include wrapping individual wires of substantially equal diameters and/or geometries. However, no particular restrictions are placed on the geometries of the wires nor on the types of materials that may be used to make the wires. Nonetheless, according to certain embodiment of the present invention, the wires can be made of galvanized steel and have diameters of approximately 0.019 inches when incorporated into 40- series push-pull cables. The process continues to step 24.

For example, additional layers may be formed on the outside of components illustrated in FIG. 2 or the components illustrated in HG. 2 may be pushed or pulled into the middle of additional components that make up push-pull cables. Control proceeds to step 28, where the process stops.
