A GEAR SHIFT LEVER ROD OF A VEHICLE FOR FACILITATING APPLICATION OF FLEXIBLE LOAD
TECHNICAL FIELD
[0001] The present disclosure relates to a gear shift lever rod of a vehicle for facilitating application of flexible load. In particular, the present disclosure relates to the lever rod capable of facilitating at least two shift lever ratio in order to enable the operator to apply flexible load by selection of appropriate lever ratio based on requirement.
BACKGROUND
[0002] A gear shift lever assembly (GSLA) also known as a transmission lever, is used to allow a vehicle to be put into different gears on a manual transmission system and is normally located between two front seats of the vehicle. Typically, the gears used in the vehicle are of a fixed height, but as per the comfort of an operator the automobile manufacturers are now focusing on more advanced mechanism to provide different options that may provide adjustability of the gears thereby enabling them to operate easily and comfortably.
[0003] Figures 1 (a) and 1 (b) show basic structure of the manual transmission system (100). The manual transmission system (100) comprises, the gear shift lever assembly (101) having a knob (101-1) which is connected at an upper end of a lever rod (101-2), a boot (101-3) which covers the lever rod (101-2), a shift pin (208) configured at the lower end of the lever rod (101-2) to select parking gear. The manual transmission system (100) further comprises a bell crank (101-4) placed in lower part of the gear shift lever assembly (101) for changing motion of the vehicle through an angle, a shifter box (101-5) configured with the shift pin (208) a select pin and a shift tower (101-7) that is assembled in a transmission unit (101-8) and connected to a select cable (101-9) from one end and to a shift cable (101-10) from the other end.
[0004] Now, if a load is to be applied to the knob (101-1) of gear shift lever for shifting, the load primarily depends on the lever ratio already set in the lever rod (101-2) of the gear shift lever assembly (101). The load applied to the knob (101-1) actuates the shift cable (101-10) and the select cable (101-9), thereby, actuating the shift tower (101-7). This in turn, shifts the gear to the selected position based on mechanism provided in the transmission unit (101-8). The lever rod (101-2) which is the part of the gear shift lever assembly (101) has been illustrated in Figure 2. The lever rod (200) comprises of an upper half lever portion (202) and a lower half lever portion (204) with a pivot ball (206) dividing the upper half lever portion (202) and the lower half lever portion (204). The pivot ball (206) is mounted on the lower end of the upper shaft (202) and the shift pin (208) that is fixed at the lower end of the lower shaft (204). The shift lever ratio being expressed as a ratio of length of the upper shaft (202) to the lower shaft (204) plays a crucial role in determining the load required to be applied on the knob (101-1) for actuation of the gear of the vehicle. However, in an existing arrangement, only one set of lever ratio is available, enabling an operator to apply a fixed amount of load everytime.
[0005] Further, as only one set of load can be applied by the operator during shifting, it leads to discomfort in driving experience to the operator. Moreover, the height of the lever is not adjustable in the existing designs of the lever thus, providing a fixed mechanism with no flexibility.
[0006] However, though there are some existing technologies providing adjustable height of the gear shift lever, but the kind of arrangement are not suitable for the operator as the lever rod designed in these scenario are completely movable, which causes distress for the operator while driving the vehicle.
[0007] Hence, towards this direction, there is a need to design and develop the lever rod that is flexible with adjustable height and overcomes the limitations posed by the already existing arrangements.

However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims.
[0041] While the embodiments of the disclosure are subject to various modifications and alternative forms, specific embodiment thereof have been shown by way of example in the figures and will be described below. It should be understood, however, that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.
[0042] The terms “comprises”, “comprising”, or any other variations thereof used in the disclosure, are intended to cover a non-exclusive inclusion, such that a device, system, assembly that comprises a list of components does not include only those components but may include other components not expressly listed or inherent to such system, or assembly, or device. In other words, one or more elements in a system or device proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or device.
[0043] The present disclosure provides a lever rod that is capable of facilitating application of flexible load as per requirement of the operator. This is achieved by providing at least two shift lever ratio in the lever rod of the same gear shift lever assembly, thereby, enabling the operator to choose the lever ratio based on requirement. The corresponding structural and functional aspects of the lever rod are elaborated in the subsequent sections.
[0044] The structural attributes of the lever rod (200) are known and have been already described with reference to Figure 2 in above mentioned sections.
[0045] Figure 3 depicts a front view and a side view of the upper half lever portion (202) in accordance with an embodiment of the present disclosure. The upper half lever portion (202), on the other hand, comprises of a moveable upper portion (202-1) and a fixed lower portion (202-2).
[0046] In an aspect, the moveable upper portion (202-1) is configured to receive a knob (302) at an upper end. The fixed lower portion (202-2) is cylindrical in nature and is slidably coupled to the moveable upper portion (202-1) with lower end of the fixed lower portion (202-2) being fixed with the pivot ball (202-6). However, an upper end of the fixed lower portion (202-2) defines a hollow cavity to receive lower end of the moveable upper portion (202-1).
[0047] In an aspect, the moveable upper portion (202-1) further comprises of a detent spring (202-5) to facilitate movement of the moveable upper portion (202-1) in a vertically upward/downward direction, further to be received by the hollow cavity of the fixed lower portion (202-2).
[0048] The fixed lower portion (202-2) is having a plurality of two holes arranged diametrically opposite to each other in order to receive balls of the detent spring (202-5) when the upper moveable portion (202-1) is pushed in the vertically downward/upward direction. The plurality of holes include (202-9), (202-10) and (202-11) present in the fixed lower portion (202-2) facilitating fixed position to mount the detent spring (202-5) to enable vertically upward/downward movement of the moveable upper portion (202-1).
[0049] In an aspect, as shown in Figure 4, the upper end of the fixed lower portion (202-2) comprises of a release device (402) having a sleeve (202-4) in order to push the balls of the detent spring (202-5) inwards. As can be seen from Figure 3, there are provided two arms (202-7) projecting outward from the sleeve (202-4) in diametrically opposite ends. The distal ends of the two arms (202-7) define a concave surface to receive spherical surface of balls of the detent spring (202-5) when the detent spring (202-5) is engaged with any of the two diametrically opposite holes.
[0050] In an aspect, upper portion of the sleeve (202-4) defines a flange extending circumferentially outwards to facilitate user to hold the release device (402) while pulling up the release device (402) from its initial position in upward direction.
[0051] In an aspect, the concave surface of the distal ends of the two arms (202-7) help in pushing balls of the detent spring (202-5) upon application of force in order to disengage balls of the detent spring (202-5) from the diametrically opposite holes.
[0052] In an aspect, as can also be seen from Figure 4, a vertical elongated groove is present on an outer surface of the fixed lower portion (202-2). The vertical elongated groove enables step wise movement of the release device (402) in case the moveable upper portion (202-1) is pushed in vertically upward direction. Additionally, the position and orientation of the vertical elongated groove and the sleeve (202-4) together prevent anti-rotation of the release device (402) as well.
[0053] In an aspect, the sleeve (202-4) of the release device (402) define a third arm (404) projecting outward from the sleeve (202-4) in between the two arms and distal end of the third arm (404) define a projection to engage with a vertical elongated groove of the fixed lower portion (202-2) to prevent anti-rotation of the release device (402) with respect to the fixed lower portion (202-2).
[0054] Furthermore, in an aspect, as per the Figure 3(a), there is provided a multi-threaded screw (202-8) in two diametrically opposite holes positioned in between the detent spring (202-5) and the sleeve (202-4) of the release device (402). The multi-threaded screw (202-8) passes through the holes of the moveable upper portion (202-1) and the fixed lower portion (202-2) and is also configured to fix position of the moveable upper portion (202-1) and fixed lower portion (202-2). The multi-threaded screw (202-8) is also configured to be locked in suitable position according to position of the detent spring (202-5) and the release device (402) when the moveable upper portion (202-1) is pushed in vertically upward or downward direction as per requirement.
[0055] In an aspect, screw receiving holes (202-12, 202-13, 202-14) of the multi-threaded screw (202-8) is positioned vertically offset to the plurality of two diametrically opposite holes (202-9, 202-10, 202-11) configured to receive the detent spring (202-5).
[0056] In an aspect, the moveable upper portion (202-1) is provided with a plurality of diametrically opposite holes (202-12), (202-13) and (202-14) to facilitate the locking in suitable position of the moveable upper portion (202-1) and the fixed lower power portion (202-2) using the multi-threaded screw (202-8) when the detent spring (202-5) is positioned at location (202-9), (202-10) and (202-11) respectively.
[0057] In an aspect, the lower end of the moveable upper portion (202-1) is defining a flange extending in circumferential outward direction. The upper end of the fixed lower portion (202-2), on the other hand, defines a flange extending in circumferential inward direction. Both the flanges are helping the moveable upper portion (202-1) to be coupled with the fixed lower portion (202-2).
[0058] In an aspect, as can be observed from Figure 3 and Figure 4, the moveable upper portion (202-1) is protruded in vertically downward direction and is having a spring (202-3) welded at the lower end. The spring (202-3) is welded in a manner such that it remains seated on the hollow cavity provided at the upper end of the fixed lower portion (202-2).
[0059] Figures 5 (a)-(c) illustrates an exemplary working of the upper half lever portion in accordance with an exemplary embodiment of the present disclosure. As already mentioned, the shift lever ratio may be defined as ratio of length of the moveable upper portion (202-1) (say A) and the fixed lower portion (202-2) (say B). Now, since the load required to shift the upper half lever portion (202) of the lever rod (200) is inversely proportional to the shift lever ratio (i.e. A/B), higher shift lever ratio corresponds to application of less load for shifting of gears and vice versa.
[0060] In an aspect, the present disclosure provides the lever rod (200) where length of the upper lever portion (202) is variable due to presence of the moveable upper portion (202-1) (i.e. A) in the upper lever portion (202).
[0061] Firstly, say, when the shift lever ratio is greater than 1 i.e. A>B, the moveable upper portion (202-1) remains in spring load position and the spring (202-3) remains uncompressed due to locking mechanism provided by the multi-threaded screw (202-8).
[0062] In an aspect, when the moveable upper lever (202-1) has to be moved in downward direction in the fixed lower lever (202-2) (i.e. position changed from Figure 5(b) to Figure 5(a)), the multi-threaded screw (202-8) is unscrewed from the two diametrically opposite holes and the release device (402) is moved upward using the sleeve (202-4). The two arms (207) are brought in contact with the detent spring (202-5), which is then pushed inward with the help of the distal ends of the two arms (202-7). As a result, the moveable upper lever (202-1) is pushed against the spring load to engage the detent spring (202-5) with two diametrically opposite holes provided on the fixed lower lever (202-2) (as shown in Fig. 5(a)). Once with the detent spring (202-5), which is then pushed inward the release device (402) moves back (free falling) to its neutral position (as shown in Fig. 3(c)) i.e. the two arms (202-7) are rested over the protruded area on the fixed lower portion (202-2).
[0063] In an aspect, additionally as shown in Figure 5 (c), when the moveable upper lever (202-1) is pushed vertically in downward direction, the release device (402) is released from the current position to engage detent spring (202-5) with the holes present in the lower portion of the moveable upper lever (202-1).
[0064] Therefore, as shown in Figures 5 (a)-(c), the moveable upper lever (202-1) can be adjusted to variable lengths L1, L2 and L3 where L1 is greater than L2 but less than L3. In this manner, variable lever ratio mechanism is conducted in the lever rod (200) of the gear shift lever assembly based on requirement of the operator.
[0065] In an aspect, the outer surface of the fixed lower portion (202-2) is provided with protrusion which engages with an elongated groove present on the outer surface of the moveable upper portion (202-1), providing an anti-rotation feature to the engagement.
[0066]
Technical Advantages
[0067] All in all, the invention described in the present disclosure is having the following advantages:
a) The lever rod (200) is having at least two set of variable load which may be applied by the operator during shifting of gears.
b) The lever rod (200) facilitates adjustment of height as per requirement.
c) The lever rod (200) is simple to design.
d) The lever rod (200) is easy to implement in working condition.
