Abstract

A shift lever assembly for a manual transmission includes a hollow shift lever having a shift knob provided thereon. A noise and vibration damper includes a hollow housing that is connected to the hollow shift lever, and a damper assembly is provided within the hollow housing of the noise and vibration damper. The damper assembly is adapted to be connected to a control member of a manually operable transmission. A line extends from the shift knob provided on the hollow shift lever and through the interior of the hollow shift lever. The line is adapted to control the operation of the manually operable transmission.

Claims (25)

1. A shift lever assembly that is adapted to be connected to a manually operable transmission including an input shaft, an output shaft, a plurality of gears selectively engagable with the input shaft and the output shaft to provide a plurality of speed reduction gear ratios therebetween, and a control member that is manually movable throughout a plurality of gear ratio positions for engaging a desired one of the plurality of speed reduction gear ratios, the shift lever assembly comprising:

a hollow shift lever including a first end, a second end, and a hollow interior that extends from the first end to the second end;

a shift knob supported on the first end of the hollow shift lever;

a switch supported on the shift knob; and

an electric or pneumatic line extending from the switch through the shift knob, the first end of the hollow shift lever, the hollow interior of the hollow shift lever, the second end of the hollow shift lever, and outwardly from the second end of the hollow shift lever.

2. The shift lever assembly defined in claim 1 wherein the switch is an electrical switch and the line is an electrical line.

3. The shift lever assembly defined in claim 1 wherein the switch is a pneumatic switch and the line is a pneumatic line.

4. The shift lever assembly defined in claim 1 wherein the second end of the hollow shift lever is closed by a plug.

5. The shift lever assembly defined in claim 4 wherein the plug has an opening formed therethrough, and wherein the line extends through the opening formed through the plug.

6. A combined manually operable transmission and shift lever assembly comprising:

a manually operable transmission including an input shaft, an output shaft, a plurality of gears selectively engagable with the input shaft and the output shaft to provide a plurality of speed reduction gear ratios therebetween, and a control member that is manually movable throughout a plurality of gear ratio positions for engaging a desired one of the plurality of speed reduction gear ratios, the combined manually operable transmission and shift lever assembly comprising:

a hollow shift lever including a first end, a second end, and a hollow interior that extends from the first end to the second end;

a shift knob supported on the first end of the hollow shift lever;

a switch supported on the shift knob; and

an electric or pneumatic line extending from the switch through the shift knob, the first end of the hollow shift lever, the hollow interior of the hollow shift lever, the second end of the hollow shift lever, and outwardly from the second end of the hollow shift lever.

7. The combined manually operable transmission and shift lever assembly defined in claim 6 wherein the switch is an electrical switch and the line is an electrical line.

8. The combined manually operable transmission and shift lever assembly defined in claim 6 wherein the switch is a pneumatic switch and the line is a pneumatic line.

9. The combined manually operable transmission and shift lever assembly defined in claim 6 wherein the second end of the hollow shift lever is closed by a plug.

10. The combined manually operable transmission and shift lever assembly defined in claim 9 wherein the plug has an opening formed therethrough, and wherein the line extends through the opening formed through the plug.

11. The shift lever assembly defined in claim 1 wherein the hollow shift lever is hollow and tubular in shape, the first end is a first axial end of the hollow shift lever, and the second end is a second axial end of the hollow shift lever that is opposite to the first axial end.

12. The shift lever assembly defined in claim 11 wherein the second axial end of the hollow shift lever is closed by a plug.

13. The shift lever assembly defined in claim 12 wherein the plug has an opening formed therethrough, and wherein the line extends through the opening formed through the plug.

14. The combined manually operable transmission and shift lever assembly defined in claim 6 wherein the hollow shift lever is hollow and tubular in shape, the first end is a first axial end of the hollow shift lever, and the second end is a second axial end of the hollow shift lever that is opposite to the first axial end.

15. The shift lever assembly defined in claim 14 wherein the second axial end of the hollow shift lever is closed by a plug.

16. The shift lever assembly defined in claim 15 wherein the plug has an opening formed therethrough, and wherein the line extends through the opening formed through the plug.
