Abstract: An assembly (102) for inhibiting wrong gear shift operation by a gear shift lever (101) is disclosed. The assembly (102) includes a pivotal latch (104); a pin (116); a star washer (118); a spring (120); and a stopper (124). The stopper (124) contacts an extension (122) of the spring (120) to restrict rotation of the pivotal latch (104) at a final position (FP) during shifting of the gear shift lever (101) from neutral to a fifth gear, and the stopper (124) contacts a second end (110) of the pivotal latch (104) to restrict rotation of the pivotal latch (104) at an initial position (IP) during shifting of the gear shift lever (101) from the fifth gear to neutral and simultaneously inhibiting movement of the gear shift lever (101) towards reverse gear. To be published with Fig. 1
[001] The present subject matter described herein, relates to gear shift control for manual transmissions in vehicle and more particularly, relates to transmissions having a reverse gear inhibitor.
BACKGROUND AND PRIOR ART:
[002] Conventional reverse inhibitors, incorporated with gear transmission systems, include a large number of components and / or require extremely accurate machining and assembly to ensure proper operation. During the gear shifting, driver applies load on a Gear shift lever assembly knob, attached to shift tower, resulting in actuation of cables which in turn actuates the gear shift. Shift tower comprises arrangement of various parts, actuation of which enable gear shifting. The conventional reverse inhibitors also contains mechanism for preventing 5* (fifth) to reverse direct gear shifting, as vehicle is at considerable speed in 5* (fifth) gear, and at reverse gear position zero speed is desirable.
[003] In current system having a basic structure of the shift tower, relative arrangement of Yoke, reverse limit and Lever reverse interlock; detent ensures that driver cannot shift to reverse from 5* (fifth) gear directly. To shift the gear in reverse one has to bring it to neutral first. The yoke is assembled with the help of pin and loaded with spring. During neutral to 5th gear shifting, the lever moves upward pushing the yoke upwards and then rotating towards 5* gear position. The yoke comes to initial position after 5* gear shift.
[004] During direct shifting from 5* to reverse, the lever moves and hit the yoke on the way thus making it impossible to shift from 5* to reverse gear directly. During shifting from 5* to neutral to reverse, the lever moves first towards right, then downward, and again upward and towards right thus avoiding hitting with the yoke. However, the conventional system is disadvantageous as it is a complex
system, costly as multiple child parts are required, and makes the overall transmission bulky.
[005] United States Patent publication US6082214 provides bolt (11) associated to a lever articulation fixed structure. The bolt (11), supported on an axially moveable tube (12) relative to a lever (10), is displaceable for surpassing an inhibitor lock (21) allowing a reverse gear to be shifted and the gear lever (10) displaceable in three shift planes (P1-P2-P3). In order to improve the gear lever (10) movement capacity, the inhibitor lock (21) is rotatably secured to the fixed structure (22) and is subjected to the action of an elastic mechanism (23) which generates a force tending to distance the lock itself (21) from the path traveled by the bolt (11) during the lever (10) handling in the first and second shift planes (P1-P2).
[006] However, the assembly, shape, operation and location of the parts mentioned in the prior art are not similar to the present disclosure.
OBJECTS OF THE INVENTION:
[007] The principal objective of the present invention is to provide an assembly for inhibiting wrong gear shift operation in a vehicle.

[0019] Fig. 1 illustrates a gear transmission system 100 including an assembly 102 for inhibiting wrong gear shift operation in a vehicle (not shown) in accordance with an embodiment of the present disclosure. In an embodiment, the assembly 102 includes a pivotal latch 104 provided proximal to a gear shift lever 101. The pivotal latch 104 defines an opening 106, an elongated first end 108 configured to contact the gear shift lever 101, and a second end 110. In an embodiment, the elongated first end 108 of the pivotal latch 104 includes a
tapered profile defining a first face 112, and a second face 114 substantially opposite to the first face 112.
[0020] The pivotal latch 104 is configured to rotate about the opening 106 based on an actuation of the gear shift lever 101. The assembly 102 further includes a pin 116 configured to receive the pivotal latch 104 about the opening 106. The assembly 102 further includes a star washer 118 configured to be received by the pin 116, such that the pivotal latch 104 is sandwiched between the pin 116 and the star washer 118. The assembly 102 further includes a spring 120 configured to be received by the pin 116 underneath the pivotal latch 104 such that the spring 116 rotates with the pivotal latch 104. The spring 120 defines an extension 122. The assembly 102 also includes a stopper 124 provided proximal to the pin 116. The stopper 124 defines a first surface 126, and a second surface 128 substantially opposite to the first surface 126.
[0021] Fig. 2 illustrates a schematic top view showing movement of the gear shift lever 101 along a path PI, relative the assembly 102, for achieving fifth gear from neutral. In operation, the gear shift lever 101 based upon a movement from the neutral, contacts the first face 112 of the pivotal latch 104 in an initial position IP of the pivotal latch 104. Further, the gear shift lever 101 push the first face 112 to rotate the pivotal latch 104 from the initial position IP to a final position FP to achieve the fifth gear. In an embodiment, the first surface 126 of the stopper 124 contacts the extension 122 to restrict rotation of the pivotal latch 104 at the final position FP during shifting of the gear shift lever 101 from neutral to the fifth gear.
[0022] Further, the gear shift lever 101 disengages with the pivotal latch 104 after achieving the fifth gear. As mentioned earlier, as the spring 120 is configured to rotate with the pivotal latch 104, a potential energy of the spring 120 increases in the final position FP based upon contacting of the extension 122 with the first surface 126 of the stopper to restrict rotation of the pivotal latch 104. Further in an embodiment, the potential energy of the spring 120 enables the pivotal latch 104
to retract back to the initial position IP from the final position FP as the gear shift lever 101 disengages with the pivotal latch 104.
[0023] Fig. 3 illustrates a schematic top view showing movement of the gear shift lever 101 along a path P2, relative the assembly 102, for achieving neutral from the fifth gear. In operation, the gear shift lever 101, based upon a movement from the fifth gear, contacts the second face 114 of the pivotal latch 104 in the initial position IP. In an embodiment, the second surface 128 of the stopper 124 contacts the second end 110 to restrict rotation of the pivotal latch 104 at the initial position IP during shifting of the gear shift lever 101 from the fifth gear to neutral. In an embodiment, the pivotal latch 104 in the initial position IP inhibits movement of the gear shift lever 101 towards the reverse gear, thereby preventing wrong gear operation at high speed to avoid damage. Further, the tapered profile of the pivotal latch 104 enables movement of the gear shift lever 101 towards the neutral in furtherance to inhibiting movement of the gear shift lever 101 towards the reverse gear.
[0024] The assembly 102 provides the following advantages (not limited) in comparison to conventional designs. The advantages include: reduced cost, simple design, compact shift tower due to elimination of child parts, compact TM case due to compact shift tower, etc.
