Transmission overdrive yoke position sensor for range trigger
Disclosed is an exemplary transmission clutch fork position sensor including an elongated bar and a clutch fork slidably engaging the elongated bar. A yoke bar includes a first end coupled to the clutch fork for concurrent movement therewith. A position sensor operably engages the yoke bar, and is operable for detecting a position of the yoke bar.
1. A transmission clutch fork shift mechanism comprising:
a first shift rail;
a second shift rail;
a clutch fork slidably engaging the second shift rail;
a lever pivotably attached to a pivot pin, the lever including a first end attached to the first shift rail for concurrent movement therewith, and a second end attached to the clutch fork for concurrent movement therewith;
a yoke bar having a first end coupled to the clutch fork for concurrent movement therewith; and
a position sensor operably engaging the yoke bar, the position sensor operable for detecting a position of the yoke bar.
2. The mechanism of claim 1 further comprising:
an elongated bar;
a second shift fork fixedly attached to the elongated bar; and
a neutral sensor plunger operably engaging the yoke bar and the elongated bar, the neutral sensor plunger moveable between a first position and a second position in response to movement of the yoke bar and the elongated bar, the first position indicative that both the first and second clutch forks are arrange in a neutral position, and the second position indicative that at least one of the first and second clutch forks are arranged in a non-neutral position.
3. The mechanism of claim 1 , wherein a longitudinal axis of the yoke bar is arranged substantially parallel to a longitudinal axis of the second shift rail.
4. The mechanism of claim 1 , wherein the shift fork is moveable in response to movement of the first shift rail.
5. The mechanism of claim 4 , wherein movement of the first shift rail in a first direction causes the shift fork to move in a second direction substantially opposite the first direction.
6. The mechanism of claim 1 further comprising a second shift fork attached to the second shift rail.
7. The mechanism of claim 1 , wherein the yoke bar is pivotably connected to the shift fork.
8. The mechanism of claim 7 , further comprising a pin attached to the yoke bar and slidably engaging at least one slot in the shift fork.
9. The mechanism of claim 7 , further comprising a pin rotatably connected to the yoke bar and slidably engaging at least one slot in the shift fork.
10. The mechanism of claim 1 , wherein the yoke bar is fixedly attached to the shift fork for concurrent movement therewith in a first direction, and slidably engages the shift fork to permit relative motion between the yoke bar and the shift fork in a second direction.
11. The mechanism of claim 10 , wherein the first direction is substantially parallel to a longitudinal axis of the second shift rail.
12. The mechanism of claim 11 , wherein the second direction is substantially perpendicular to the first direction.
13. The mechanism of claim 1 further comprising:
a second clutch fork fixedly attached to the second shift rail; and
a neutral sensor plunger operably engaging the yoke bar and the second shift rail, the neutral sensor plunger moveable between a first position and a second position in response to movement of the yoke bar and the second shift rail, the first position indicative that both the first and second clutch forks are arrange in a neutral position, and the second position indicative that at least one of the first and second clutch forks are arrange in a non-neutral position.
14. The mechanism of claim 1 further comprising:
a third shift rail;
a second shift fork fixedly attached to the third shift rail; and
a neutral sensor plunger operably engaging the yoke bar and the third shift rail, the neutral sensor plunger moveable between a first position and a second position in response to movement of the yoke bar and the third shift rail, the first position indicative that both the first and second clutch forks are arrange in a neutral position, and the second position indicative that at least one of the first and second clutch forks are arranged in a non-neutral position.
15. The mechanism of claim 1 , wherein a longitudinal axis of the yoke bar is arranged substantially parallel to a longitudinal axis of the second shift rail.
16. The mechanism of claim 8 , wherein at least one end of the pin includes a generally rectangular shaped end engaging the at least one slot in the shift fork.
17. The mechanism of claim 9 , wherein at least one end of the pin includes a generally rectangular shaped end engaging the at least one slot in the shift fork.
