DESC:CROSS REFERENCE TO RELATED APPLICATION
This Application is based on and derives the benefit of Indian Provisional Application 202311083619 filed on 7th December 2023, the contents of which are incorporated herein by reference.
TECHNICAL FIELD
[001] The embodiments herein generally relate to a forward-reverse shuttle transmission in a vehicle and more particularly to a system and a method for locking the forward-reverse shuttle transmission of the vehicle in a neutral position, a forward position and a reverse position.
BACKGROUND
[002] Generally, vehicles such as tractors often requires to be moved in forward and reverse directions, therefore frequent shifting of a gear shift lever is required to move the tractor in forward and reverse directions. To eliminate this problem and to reduce the fatigue to the driver due to shifting of the gear shift lever, a forward-reverse shuttle transmission was introduced in the vehicle. The forward-reverse shuttle transmission is used to provide a smooth transition during change in the operating direction of travel of the vehicle from forward to reverse direction and vice versa, without shifting of the gear shift lever. For example, the forward-reverse shuttle transmission in vehicles such as tractors and other construction vehicles have a shuttle lever for selecting the direction of travel in addition to the gear shift lever for selecting gears. Typically, the shuttle lever is provided on a left side of the Operator. The shuttle lever is provided to improve the efficiency and ease of use of the vehicle, specifically for performing tasks which require repeated and quick direction changes. Further, the forward-reverse shuttle lever is independent of the gear shift lever. During operation of the vehicle, any unintentional movement of the shuttle lever may lead to sudden movement of the vehicle in undesired direction thereby resulting in accidents causing injury to operators or other persons nearby the vehicle, or cause damages to the vehicle or any other property. Further, the forward-reverse shuttle lock is provided in vehicles for safety of transmission gear train. Therefore, any sudden engagement and disengagement of the shuttle lock may lead to damage of gears of the transmission system.
[003] Therefore, there exists a need for a system and a method for locking the forward-reverse shuttle transmission of the vehicle which obviates the aforementioned drawbacks.

[0027] The embodiments herein achieve a system (shuttle transmission locking system) and a method for locking a forward-reverse shuttle transmission of the vehicle in a neutral position, a forward position and a reverse position. Further, embodiments herein achieve the shuttle transmission locking system for locking a shuttle lever thereby ensuring safety of operator (driver) and prevents damage to vehicle transmission by pre-empting inadvertent movement of the shuttle lever. Referring now to the drawings Figs. 1 through 9, where similar reference characters denote corresponding features consistently throughout the figures, there are shown embodiments.
[0028] Fig. 1 depicts a perspective view of a system (100) for locking a forward-reverse shuttle transmission (10) of a vehicle, according to embodiments as disclosed herein. In an embodiment, the system (100) (shuttle transmission locking system) includes a first locking member (102), a pivot lever (104), a second locking member (106), a bracket (108), a pivot pin (110), a support pin (112) and a pin (114). For the purpose of this description and ease of understanding, the system (100) is explained herein below with reference to locking the shuttle lever (18) of the forward-reverse shuttle transmission (10) of the vehicle such as but not limited to agricultural vehicles (tractors). However, it is also within the scope of the invention to use/practice the components of the system (100) for locking any of the shuttle lever or shuttle linkages or shuttle transmission mechanisms of a combine harvester, constructions vehicles or any other vehicles without otherwise deterring the intended function of the system (100) as can be deduced from the description and corresponding drawings. The forward-reverse shuttle transmission (10) is used to provide a smooth transition during change in the operating direction of travel of the vehicle from forward to reverse direction and vice versa, without shifting of a gear shift lever (not shown) of the vehicle. The shuttle lever (18) of the forward-reverse shuttle transmission (10) is configured to be operated in one of a forward position, a reverse position and a neutral position. In the forward position of the shuttle lever (18), the vehicle is configured to be moved along the forward direction. In the reverse position of the shuttle lever (18), the vehicle is configured to be moved along the reverse direction. The system (100) is configured to be operated in one of an unlocked position and a locked position. In the unlocked position, the shuttle lever (18) of the forward-reverse shuttle transmission (10) is configured to be operated freely in one of the forward position, the neutral position and the reverse position. In the locked position, the shuttle lever (18) of the forward-reverse shuttle transmission (10) is configured to be locked in the selected position (forward or reverse or neutral positions) thereby restricting movement of the shuttle lever (18) and a shuttle shaft (16). The shuttle lever (18) is connected to the shuttle shaft (16) which in turn is operatively connected to forward or reverse transmission gears of the forward-reverse shuttle transmission (10) through linkage(s) (not shown). Therefore, locking the shuttle shaft (16) prevents inadvertent changing of forward or reverse transmission gears which in turn ensures safety of operator and prevents damage to the transmission of the vehicle.
[0029] The first locking member (102) is provided on the shuttle shaft (16) of the forward-reverse shuttle transmission (10). It is also within the scope of the invention to provide the first locking member (102) on any other linkages of the forward-reverse shuttle transmission (10). A first end (104f) (as shown in fig. 3) of the pivot lever (104) is adapted to be pivotably coupled to a pedal mounting bracket (12) (as shown in fig. 2) of the vehicle through the bracket (108) and the pivot pin (110). A second end (104s) (as shown in fig. 3) of the pivot lever (104) is adapted to be movably connected to a clutch pedal (14) (as shown in fig. 3) of the vehicle through the support pin (112). The pivot lever (104) is used to transmit the movement of the clutch pedal (14) to the second locking member (106) through the pin (114) thereby moving the second locking member (106) to one of the unlocked position and the locked position when the clutch pedal is pressed and released respectively. The first end (104f) of the pivot lever (104) is adapted to be pivotably connected to the bracket (108) through the pivot pin (110). In an embodiment, the pivot lever (104) includes a sleeve (104A) at its first end (104f), and an arm (104B) transversely extending from the sleeve (104A). The arm (104B) of the pivot lever (104) includes an elongated slot (104BS) (as shown in fig. 4) near its second end (104s). The elongated slot (104BS) of the pivot lever (104) is adapted to facilitate movably mounting of the second end (104s) of the pivot lever (104) onto the support pin (112) (as shown in fig. 4) affixed to the clutch pedal (14). The support pin (112) is connected to a clutch pedal shank of the clutch pedal (14) and is received by the elongated slot (104BS) of the pivot lever (104). A washer (not shown) is mounted onto the support pin (112), and a retaining pin (not shown) is inserted into the support pin (112) to facilitate movable mounting of the second end (104s) of the pivot lever (104) with respect to the support pin (112).
[0030] The second locking member (104) is movably placed on the bracket (108) and a first end (106f) (as shown in fig. 4) of the second locking member (104) is adapted to be connected to the pivot lever (104) through the pin (114). For example, one end of the pin (114) is connected to the arm (104B) of the pivot lever (104) and another end of the pin (114) is configured to be freely received by a hole (not shown) provided in the first end (106f) of the second locking member (106). An outer diameter of the pin (114) is smaller than a size of the hole (not shown) provided in the first end (106f) of the second locking member (106). The pin (114) is configured to convert the rotary motion of the pivot lever (104) into linear movement of the second locking member (106) thereby moving the second locking member (106) to one of the unlocked position and the locked position when the clutch pedal (14) is pressed and released respectively. The second locking member (106) is configured to linearly move in a direction towards the first locking member (102) for engaging the second end (106s) of the second locking member (106) with the first locking member (102) thereby locking the shuttle lever (12) when second locking member (106) is pushed by the pin (114) in response to pressing of the clutch pedal (14). Further, the second locking member (106) is configured to linearly move in a direction away from the first locking member (102) for disengaging the second end (106s) of the second locking member (106) from the first locking member (102) thereby unlocking the shuttle lever (12) when second locking member (106) is pulled by the pin (114) in response to releasing of the clutch pedal (14). In the unlocked position, the second end (106s) of the second locking member (106) is disengaged from the first locking member (102) and is resting on the slot (108S) of the bracket (108) as shown in fig. 5.

In an embodiment, the first locking member (102) includes a sleeve (102A), a first portion (102B), a first locking wall (102C), an intermediate wall (102D) and second locking wall (102E). The sleeve (102A) of the first locking member (102) is adapted to be received by the shuttle shaft (16) and is affixed to the shuttle shaft (16) by using fasteners (bolt). The first portion (102B) of the first locking member (102) is adapted to extend from the sleeve (102A) of the first locking member (102) in an upward direction towards the second end (106s) of the second locking member (106). The first locking wall (102C) of the first locking member (102) is disposed on the first portion (102B). The intermediate wall (102D) of the first locking member (102) transversely extends from corresponding end of the first locking wall (102C) and is disposed on the first portion (102B). The second locking wall (102E) of the first locking member (102) transversely extends from corresponding side of the intermediate wall (102D) and is positioned parallel to and spaced part from the first locking wall (102C), wherein the second locking wall (102E) is disposed on the first portion (102B). In an embodiment, the first locking wall (102C), the intermediate wall (102D) and the second locking wall (102E) are adapted to define a space (102SP) therebetween to receive the second end (106s) of the second locking member (106) therethrough to engage the second locking member (106) with the first locking member (102) thereby locking the shuttle lever (18) in the neutral position (as shown in fig. 6a). Further, the second end (106s) of the second locking member (106) is adapted to disengage from the first locking member (102) when the second locking member (106) is moved to the unlocked position for unlocking the shuttle lever (18) from the neutral position (as shown in fig. 6b) to move the shuttle lever (18) to one of the forward position or the reverse position. Further, the second end (106s) of the second locking member (106) is adapted to engage with the first locking wall (102C) of the first locking member (102) thereby locking the shuttle lever (18) in the forward position (as shown in fig. 7a) when the second locking member (106) is moved to the locked position. Furthermore, the second end (106s) of the second locking member (106) is adapted to disengage from the first locking wall (102C) of the first locking member (102) of the first locking member (102) when the second locking member (106) is moved to the unlocked position for unlocking the shuttle lever (18) from the forward position (as shown in fig. 7b) to move the shuttle lever (18) to one of the neutral position or the reverse position. Further, the second end (106s) of the second locking member (106) is adapted to engage with the second locking wall (102E) of the first locking member (102) thereby locking the shuttle lever (18) in the reverse position (as shown in fig. 8a) when the second locking member (106) is moved to the locked position. Furthermore, the second end (106s) of the second locking member (106) is adapted to disengage from the second locking wall (102E) of the first locking member (102) when the second locking member (106) is moved to the unlocked position for unlocking the shuttle lever (18) from the reverse position (as shown in fig. 8b) to move the shuttle lever (18) to one of the neutral position or the forward position.
[0032] The steps involved in switching from the neutral position and the locked position of the shuttle lever (18) to forward position and locked position of the shuttle lever (18), is described hereinbelow as an example. In operation, when the operator actuates/ presses the clutch pedal (14), the support pin (112) rotates the pivot lever (104) which in turn moves the second end (106s) of the second locking member (106) away from the space (102SP) of first locking member (102) to disengage the second locking member (106) from the first locking member (102) thereby unlocking the shuttle lever (18) from the neutral position. Thereafter, the operator move the shuttle lever (18) to the forward position while maintaining pressing of the clutch pedal (14). Subsequently, when the clutch pedal (14) is released, the support pin (112) rotates the pivot lever (104) which in turn moves the second locking member (106) in a direction towards the first locking member (102) to engage the second end (106s) of the second locking member (106) with the first locking wall (102C) of the first locking member (102) thereby locking the shuttle lever (18) in the forward position. This restricts the movement of the shuttle lever (18) to the neutral or reverse positions. With the aforementioned system (100), inadvertent movement of the shuttle lever (18) from forward position to neutral position and reverse position is pre-empted.
[0033] Fig. 9 depicts a flowchart indicating steps of a method (300) for locking the forward-reverse shuttle transmission (10) of the vehicle, according to embodiments as disclosed herein. At step (302), the method (300) includes pivotably mounting the first end (104f) of the pivot lever (104) onto the pedal mounting bracket (12) of the vehicle via the bracket (108) and the pivot pin (110), and movably mounting the second end (104s) of the pivot lever (104) onto the clutch pedal (14) of the vehicle via the support pin (112). At step (304), the method (300) includes affixing the first locking member (102) onto the shuttle shaft (16) of the forward-reverse shuttle transmission (10). At step (305), the method (300) includes inserting a second locking member (106) into a slot (108S) provided on the bracket (108), and connecting one end of the second locking member (106) to the pivot lever (104) through a pin (114) in which one end of the pin (114) is connected with the pivot lever (104) and another end of the pin (114) is freely received by a hole provided on the second locking member (106). At step (306), the method (300) includes moving, by the pivot lever (104), the second locking member (106) to the unlocked position in which the second locking member (106) is disengaged from the first locking member (102) thereby unlocking the shuttle lever (18) of the forward-reverse shuttle transmission (10) upon pressing the clutch pedal (14) of the vehicle. At step (308), the method (300) includes moving, by the pivot lever (104), the second locking member (106) to the locked position in which the second locking member (106) is engaged with the first locking member (102) thereby locking the shuttle lever (18) when the clutch pedal (14) is released.
[0034] The embodiments described herein above have several technical advantages including, but not limited to, realization of the system (100) for locking the forward-reverse shuttle transmission (10) of the vehicle. The shuttle transmission locking system (100) allows reliable locking of the shuttle lever (18). The shuttle transmission locking system (100) is easy to operate and prevents inadvertent movement of shuttle lever (18) and ensures locking of shuttle lever (18) in forward, neutral, and reverse positions. The shuttle transmission locking system ensures safety of operator (driver) and prevents damage to vehicle transmission by pre-empting inadvertent movement of the shuttle lever (18). The shuttle transmission locking system allows actuation of the shuttle lever (18) when the clutch pedal (14) is operated, thereby preventing unintentional operation of the shuttle lever (18).

the second locking member (106) is configured to linearly move in a direction away from the first locking member (102) for disengaging the second end (106s) of the second locking member (106) from the first locking member (102) thereby unlocking the shuttle lever (12) when second locking member (106) is pulled by the pin (114) in response to releasing of the clutch pedal (14).
10. A method (300) for locking a forward-reverse shuttle transmission (10) of a vehicle, the method (300) comprising:
pivotably mounting a first end (104f) of a pivot lever (104) onto a pedal mounting bracket (12) of the vehicle via a bracket (108) and a pivot pin (110), and movably mounting a second end (104s) of the pivot lever (104) onto a clutch pedal (14) of the vehicle via a support pin (112);
affixing a first locking member (102) onto a shuttle shaft (16) of the forward-reverse shuttle transmission (10);
freely inserting a second locking member (106) into a slot (108S) provided on the bracket (108), and connecting one end of the second locking member (106) to the pivot lever (104) through a pin (114) in which one end of the pin (114) is connected with the pivot lever (104) and another end of the pin (114) is freely received by a hole provided on the second locking member (106);
moving, by the pivot lever (104), the second locking member (106) to an unlocked position in which the second locking member (106) is disengaged from the first locking member (102) thereby unlocking a shuttle lever (18) of the forward-reverse shuttle transmission (10) upon pressing a clutch pedal (14) of the vehicle; and
moving, by the pivot lever (104), the second locking member (106) to a locked position in which the second locking member (106) is engaged with the first locking member (102) thereby locking the shuttle lever (18) when the clutch pedal (14) is released.
