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.
Claims20
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 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;
- 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;
- and
- a noise and vibration damper assembly including a hollow housing that is connected to the second end of the hollow shift lever and a damper mechanism supported within the hollow housing, wherein the damper mechanism is adapted to be connected to a control member of a manually operable transmission.
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 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;
- 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;
- and
- a noise and vibration damper assembly including a hollow housing that is connected to the second end of the hollow shift lever and a damper mechanism supported within the hollow housing, wherein the damper mechanism is connected to a control member of a manually operable transmission.
