TECHNICAL FIELD
Present disclosure, in general, relates to a field of automobiles. Particularly, but not exclusively, the present disclosure relates to gear shifting mechanism/assembly of a vehicle. Further, embodiments of the present disclosure relate to a shifter assembly of a gearbox of the vehicle.
BACKGROUND OF THE DISCLOSURE
Vehicles are equipped with a gearbox which is connected to a flywheel of an engine via a clutch to transmit torque to wheels of the vehicle. Generally, two types of gearboxes have been predominantly used, namely a manual gearbox and an automatic gearbox. The manual gearbox requires an operator to shift between gears, while the automatic gearbox changes gears based on vehicle operating conditions or other prerequisite parameters.
Typically, gear shifting in the manual gearbox, requires effort and skill from an operator. The operator needs to operate a shift lever in a cabin of the vehicle, along with operation of a clutch for shifting to the required gear and in-turn regulate movement of the vehicle. Movement of the shift lever in the predefined pattern results in a linear displacement, of a connecting member such as a shift cable or shifting rod connecting the shift lever and the gearbox, which is transmitted to the gearbox to facilitate shifting of gears. However, shifting of gears in the manual gearbox requires effort and skill from the operator and such effort required for shifting the gears increases with increase in capacity of the engine and gearbox. Further, the shift lever needs to be returned to neutral position from the selected gear.
Considering the above, with advancements in technology, a combination of torsional springs and compression springs are configured to assist the operator by reducing the effort required to return the shift lever to neutral. However, such configurations occupy large space and result in complicated arrangement of the shift lever. Further, torsional springs are prone to failure due to high twisting forces during the shifting of gears between extreme gears such as a first gear and a reverse gear, thereby requiring frequent replacement.
The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional mechanisms.

Embodiments of the present disclosure discloses a shifter assembly of a gearbox. The shifter assembly comprises a base member, a shift lever, a pivoting plate, at least two cams and a pair of followers. The shift lever is removably connected to the base member and a mounting plate and is configured to shift between a plurality of gates. The pivoting plate is pivotably mounted on the base member and is configured to receive the mounting plate. The at least two cams are connected to the pivoting plate and extend between the pivoting plate and the base member. Each follower

of the pair of followers is movably positioned in the base member and is configured to contact a surface of the at least two cams.

With such configuration, the assembly may improve returnability of the shift lever to neutral position and may minimize or eliminate failure of the shift lever by employing a cam and follower arrangement.
The disclosure is described in the following paragraphs with reference to Figures 1a to 5d. In the figures, the same element or elements which have same functions are indicated by the same reference signs. It is to be noted that, the vehicle is not illustrated in the figures for the purpose of simplicity. One skilled in the art would appreciate that the assembly as disclosed in the present disclosure may be used in any vehicle including but not limited to heavy and light commercial vehicles, load carrying vehicles, passenger vehicles, and the like. The system and the method of the present disclosure may also be implemented in vehicles having manual transmission for suitably maneuvering the vehicle without deviating from the principles of the present disclosure.
Figures 1a to 1d refer to different schematic views of a shifter assembly (100) of a gearbox. The shifter assembly (100) [hereinafter interchangeably referred to as “assembly (100)”] may be positioned in a cabin of a vehicle (not shown in figures) and may be coupled to the gearbox (not shown in figures) of the vehicle. In an embodiment, the term “shift gears” may be inferred to as both up-shifting and down-shifting of gears, which is performed by an operator as per requirement. The shifter assembly (100) includes a base member (1), a shift lever (2), a pivoting plate (4), at least two cams (5a, 5b) and a pair of followers (6a, 6b). The shift lever (2) is removably connected to the base member (1) and a mounting plate (3), where the shift lever (2) is operable by the operator for shifting between a plurality of gates which in-turn operates for selection and shifting between a plurality of gears of the gearbox. In an embodiment, the cabin of the vehicle may comprise a guide plate connectable to a housing of the gearbox comprising plurality of gates that indicate number of gears of the gearbox in the vehicle.

The base member (1) may be defined with at least two vertical projections (12a and 12b) [hereinafter referred to as vertical projections] such as a first vertical projection (12a) and a second vertical projection (12b). The first vertical projection (12a) and the second vertical projection (12b) may be defined with at least one opening to allow a first pin (7) to be positioned across the vertical projections (12a and 12b) for pivotably connecting the pivoting plate (4) to the base member (1). The pivoting plate (4) may be defined with a first cylindrical cavity to rotatably position the first pin (7). The first pin (8) may be configured to extend out from the first cylindrical cavity of the pivoting plate (4) to fit into the at least one opening of the first vertical projection (12a) and the second vertical projection (12b) to allow pivotal movement of the pivoting plate (4) about the first pin (7). The pivoting plate (4) may be configured to receive the mounting plate (3) by a second pin (8), where the second pin (8) may be rotatably positioned in a second cylindrical cavity defined within the pivoting plate (4). The second pin (8) may be configured to extend out from the second cylindrical cavity of the pivoting plate (4). The second pin (8) may be positioned perpendicular to the first pin (7), where the mounting plate (3) may be connectable across ends of the second pin (8) extending from the second cylindrical cavity to allow pivotable movement of the mounting plate (3) about the second pin (8). In an embodiment, the mounting plate (3) may be defined with a profile resembling at least one of C-shaped, double L shape, and the like. In the illustration, the mounting plate is depicted to be a U-shaped plate, where ends of the U-shaped plate may be connected to the second pin (8) at extending portions of the second pin (8) from the cylindrical cavity as best seen in Figure 2. The mounting plate (3) may be configured to receive the shift lever (2) on top between the ends of the mounting plate (3). The mounting plate (3) and the pivoting plate (4) displace about the first pin (7) when the shift lever (2) is displaced sideways i.e., in a left and a right directions to shift between the plurality of gates, whereas the mounting plate (3) and the pivoting plate (4) are displaced about the second pin (8) when the shift lever (2) is displaced forward and backward to shift between gears of the plurality of gates.
Referring to figure 1b, which is a magnified view of the shifter assembly (100). The pivoting plate (4) is defined with at least two cams (5a, 5b) on the bottom extending between the pivoting plate (4) and the base member (1). The pair of followers may comprise a first follower (6a) and a second follower (6b) movably positioned within the base member (1) and below the pivoting plate (4). The followers are depicted as a pair in number, however the number of followers shall not be

considered a limitation. The first follower (6a) and the second follower (6b) are each configured to contact a surface of each cam of the at least two cams (5a, 5b). The first follower (6a) and the second follower (6b) are configured to displace the shift lever (2) to align the shift lever (2) with at least one gate of the plurality of gates. The mounting plate (3) and the pivoting plate (4) are pivotably displaced about the first pin (7) due to sideways displacement of the shift lever (2) which in-turn selectively biases the first follower (6a) and the second follower (6b) based on selection of a gate from the plurality of gates. The shift lever (2) may be selectively displaced between a first position and a second position upon pivotal movement of the mounting plate (3). The shift lever (2) displaces to a neutral position from the first position and the second position upon disengaging from the at least one gate of the plurality of gates.
In an embodiment, the shift lever (2) may be displaced pivotably to shift between the plurality of gates. In an embodiment, the plurality of gates may be arranged in an H-shifting pattern or a combination pattern as per requirement. The shift lever (2) may be pivotably displaced to thereby displace the pivoting plate (4) about the first pin (7) to a first position and a second position for selecting at least one gate of the plurality of gates. The shift lever (2) may be configured to be displaced to a neutral position upon disengaging from the at least one gate of the plurality of gates. For sake of explanation, the guide plate is defined to include at least four gates such as a first gate, a second gate, a third gate and a fourth gate and the same shall not be considered a limitation. The first gate may correspond to a shift lever (2) position for selecting a first gear and a second gear of the gearbox. The second gate may correspond to a shift lever (2) position for selecting a neutral gear, a third gear and a fourth gear of the gearbox. The third gate may correspond to a shift lever (2) position for selecting a fifth gear and a sixth gear of the gearbox. The fourth gate may correspond to the shift lever (2) position for selecting a reverse gear of the gearbox. The position of the reverse gear is depicted in the illustrative embodiment to be on an extreme of left side of the plurality of gates for sake of explanation and the same shall not be considered a limitation. The first position may be defined where the shift lever (2) is engaged in the first gate of the gearbox. The second position may be defined as a position where the shift lever (2) is engaged in the second gate. The first gate may be defined on one side of the second gate and the third gate may be defined on the an other side opposite to the one side of the second gate. The second gate may correspond

to the neutral gear of the gearbox, where the shift lever (2) may return to the second gate upon disengagement from gears of the first gate, the second gate, third gate and the fourth gate.
The displacement of the shift lever (2) between the first gate, the second gate and the third gate may pivotally displace the mounting plate (3) and in-turn displace the pivoting plate (4) about the first pin (7). The pivoting plate (4) may be configured with at least two cams (5a, 5b) extending between the pivoting plate (4) and the base member (1). The at least two cams (5a, 5b) may comprise a first cam (5a) and a second cam (5b), where the first cam (5a) may be defined on one end of the pivoting plate (4) and the second cam (5b) may be defined on an other end of the pivoting plate (4) as best seen in Figure 1b. The surfaces of the first cam (5a) and the second cam (5b) may comprise an arcuate surface or a curved surface. In an embodiment, each of the first cam (5a) and the second cam (5b) may be defined with a linear portion extending from the curved surface. The curved surface may define substantial portion of circumference/arc of a circular or a semi-circular profile. In an embodiment, the base member (1) may be defined with at least two hollow portions (11a, 11b), where the pair of followers (6a, 6b) are movably positioned in the at least two hollow portions (11a, 11b). Each of the pair of followers (6a, 6b) may include a plunger such as a first plunger (9a) and a second plunger (9b) and a resilient member such as a first resilient member (10a) and a second resilient member (10b) positioned within the at least two hollow portions (11a, 11b) as best seen in Figure 2. In the illustrative embodiment, the first resilient member (10a) and the second resilient member (10b) include a compression spring configured to bias the first plunger (9a) and the second plunger (9b) respectively. Further, the first plunger and the second plunger are illustrated with a pin profile and the same shall not be considered a limitation. The first resilient member (10a) and the second resilient member (10b) are positioned within the at least two hollow portions (11a, 11b) such as a first hollow portion (11a) and a second hollow portion (11b) of the base member (1) i.e., the first resilient member (10a) is displaceably positioned in the first hollow portion (11a) and the second resilient member (10b) is displaceably positioned in the second hollow portion (11b). The first plunger (9a) and the second plunger (9b) are positioned above the first resilient member (10a) and the second resilient member (10b).
In an embodiment, when the shift lever (2) is engaged in the first gate, the shift lever (2) is displaced to the first position. In the first position, the first plunger (9a) is configured to contact

the first cam (5a) and ride along the surface of the first cam (5a) to compress the first resilient member upon displacement of the shift lever (2). The first resilient member may be configured to expand upon disengaging the shift lever (2) from the first position, where the first plunger (9a) may be configured to ride along the surface of the first cam (5a) while pushing the first cam (5a) thereby displacing the shift lever (2) to the neutral position in the second gate by displacing the pivoting plate (4) about the first pin (7). Similarly, when the shift lever (2) is engaged in the third gate, the shift lever (2) is displaced to the second position. In the second position, the second plunger (9b) is configured to contact the second cam (5b) and ride along the surface of the second cam (5b) to compress the second resilient member upon displacement of the shift lever (2). The second resilient member may be configured to expand upon disengaging the shift lever (2) from the second position, where the second plunger (9b) may be configured to ride along the surface of the second cam (5b) while pushing the first cam (5a) thereby displacing the shift lever (2) to the neutral position in the second gate by displacing the pivoting plate (4) about the first pin (7).
Referring now to Figures 1c,1d, and 3, the pivoting plate (4) may be defined with a first horizontal projection (13a). The first horizontal projection (13a) may be connected to a selection cable (14b) of the gearbox in the vehicle configured to select the at least one gate based on the movement of the mounting plate (3). Further, the mounting plate (3) may be defined with a second horizontal projection (13b) as seen in Figure 1c and Figure 1d. The second horizontal projection (13b) may be connected to a shift cable (14a) of the gearbox in the vehicle configured to shift the gears based on the movement of the mounting plate (3) as best seen in Figure 3. In an embodiment, stiffness of the first resilient member (10a) and the second resilient member (10b) may be varied based on the requirement to vary the effort required from the operator to displace the shift lever while operating the selection cable (14b) and/or the shift cable (14a).
Referring now to Figures 4a to 4d and 5a to 5d, which illustrate different positions of the assembly (100) while shifting between the first position, the second position, a third position and the neutral position. The position of the assembly (100) when the shift lever (2) may not displaced i.e., at the neutral position is depicted in Figures 4b and 5b. The first plunger (9a) and the second plunger (9b) may not be biased in neutral position of the shift lever (2). The configuration of the assembly (100) when the shift lever (2) may be displaced to a first position is depicted in Figures 4a and 5a. The shift lever (1) is displaced towards the right side in the first position, where the mounting plate

is pivotably displaced about the first pin (7) towards the second plunger (9b). The second resilient member (10b) beneath the second plunger (9b) may be compressed by the second cam (5b) through the second plunger (9b), while the first plunger (9a) is not compressed and may not have contact with the first cam (5a) as best seen in Figures 4a and 5a. When the shift lever may be disengaged from the first position, the second resilient member (10b) may be configured to expand thereby biasing the second plunger (9b) and displacing the shift lever (2) about the first pin (7) and thereby biasing the shift lever (2) to the neutral position from the first position as seen in Figures 4b and 5b. Similarly, the shift lever (2) may be displaced to the second position as seen in Figures 4c and 5c, where the shift lever (2) may be displaced towards left side. In such configuration, the first cam (5a) may push the first plunger (9a) downwards to compress the first resilient member (10a), where the second plunger (9b) may not be compressed and may not have contact with the second cam (5b). Upon disengagement, the first resilient member (10a) may be configured to bias the first plunger (9a) to ride along the first cam (5a) thereby pushing the mounting plate (3) to displace pivotally about the first pin (7) as best seen in Figure 5c. Thus, the first resilient member and the first plunger (9a) may displace the shift lever (2) to the neutral position as seen in Figures 4b and 5b. Further, the shift lever may be displaced to the third position towards an extreme on the right side corresponding to the reverse gear of the gearbox, where the shift lever (2) is displaced towards an extreme gate of the plurality of gates as seen in Figures 4d and 5d, where the shift lever (2) may be displaced towards left side. In such configuration, the first cam (5a) may push the first plunger (9a) downwards to compress the first resilient member (10a), where the second plunger (9b) may not be compressed and may not have contact with the second cam (5b) as seen in Figure 4d. The first resilient member (10a) may be compressed to an extent greater than compression in the second position as best seen in Figure 5d. Upon disengagement, the first resilient member (10a) may be configured to bias the first plunger (9a) to ride along the first cam (5a) thereby pushing the mounting plate (3) to displace pivotally about the first pin (7) to the second position as seen in Figure 4c. Further, the first resilient member and the first plunger (9a) may displace the shift lever (2) to the neutral position as seen in Figures 4b and 5b.
In an embodiment, the assembly (100) may be mounted on a dashboard of the vehicle as seen in Figures 1a and 3 or may be mounted on a hump/console/floor of the vehicle as seen in Figures 1c and 1d.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used,

in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
