A GUTTER ASSEMBLY TO FACILITATE LUBRICATION OF TRANSMISSION PARTS IN A TRANSMISSION CASING
TECHNICAL FIELD
[0001] The present disclosure relates to a gutter assembly to facilitate lubrication of remote transmission parts of a vehicle transmission. In particular, the present disclosure relates to the gutter assembly capable of collecting oil flowing on top surface of a flap of an oil gutter and disperse the collected oil to the remote areas of the vehicle transmission in order to improve lubrication.
BACKGROUND
[0002] Typically, in a transmission of a vehicle, continuous lubrication of certain parts, for example, gear teeth, bearings, etc. are required. This is due to the fact that these parts are in dynamic contact with other parts resulting in heat generation due to friction between these parts and therefore lubrication is necessary in order to cool the surfaces by carrying away heat. Another purpose of lubrication is to absorb shock between bearings and other parts and thereby reducing the resulting noise. Additionally, lubrication of transmission also helps to clean the surfaces of the transmission parts accumulated with carbon and metal particles caused by regular wear and tear. Consequently, in order to mitigate such circumstances, oil galleries and oil gutters are provided in a transmission system to supply oil in the critical and remote areas.
[0003] In splash method of lubrication, lubrication of the transmission is performed by splashing the oil with the help of rotating gears. A large amount of oil is being splashed in the air inside the transmission housing and thus due to random splashing, some areas are not sufficiently lubricated due to remote location.
[0004] In order to circumvent such challenges, as shown in Figure 1 (100), an oil gutter (102) is provided in a transmission casing (104) for lubricating remote transmission parts of the vehicle transmission. As shown in Figure 2 (200), the oil gutter (102) is affixed to a mounting plate (106) and is provided with a flap (202), where the flap (202) diverts the oil splash generated by gears to the oil gutter (102) thereby increasing the oil flow rate. The oil gutter (102) collects the splashed oil and transmits oil to the remote transmission parts of the vehicle transmission.
[0005] However, in certain circumstances, flow of oil through the oil gutter (102) is compromised. This may be due to the fact that oil splash being too high may pass over the flap (202) and thus unable to reach the oil gutter (102). Also, since splashing of oil is performed with the help of rotating gears, the splashed oil strikes on top surface of the flap (202) and therefore keep on draining/dropping below due to gravity and absence of suitable arrangement for collection of the splashed oil. Thus, this leads to wastage of the splashed oil and it cannot be guided for lubrication of the transmission parts.
[0006] Towards this direction, there is a need to develop a suitable structure such that the wastage of lubricant may be prevented and the lubricating oil may find proper utilization.

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.
[0036] 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.
[0037] 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.
[0038] The present disclosure relates to a gutter assembly to facilitate lubrication of remote transmission part of a vehicle transmission. The gutter assembly is designed in a manner such that the splashed oil reaching top surface of a flap (202) is not wasted and is guided properly for lubricating the remote transmission parts. The structural attributes of the invention as disclosed in the present subject matter has been detailed in subsequent sections.
[0039] Referring to Figure 3, there is provided a gutter assembly (300) in order to facilitate lubrication of remote transmission parts. The gutter assembly (300) comprises of an oil gutter (102) and the flap (202).
[0040] In an aspect, the oil gutter (102) is positioned in transverse direction to the transmission casing and the flap (202) is affixed with the oil gutter (102). The flap (202) further comprises of a vertical portion (204) and an inclined portion (206).
[0041] In an aspect, the vertical portion (204) is attached with the oil gutter (102) from one end and protrude vertically upward from the oil gutter (102) upto a bent edge (208). The inclined portion (206), on the other hand, is angularly extended in forward direction towards transmission parts of the transmission casing (104) from the bent edge (208) and allows diversion of splashed oil generated in the transmission casing (104) to the oil gutter (102). The corresponding angle formed by the inclined portion (206) may range from 30 to 60 degree, preferably 45 degrees. The angle may vary depending upon relative position of the gutter with respect to gears creating oil splash.
[0042] In an aspect, as shown in Figure 3, the flap (202) is provided with at least one slot (302) adjacent to the bent edge (208). The at least one slot (302) may be a longitudinal slot provided along width of the flap (202). Herein, the at least one slot (302) is covered to define a pocket structure (304) that is able to guide the splashed oil reaching on top surface of the flap (202) to the oil gutter (102). Consequently, this arrangement prevents wastage of splashed oil from top surface of the flap and also lubricates remote transmission part through the guided arrangement.
[0043] Referring to Figure 4 (400), the flap (202) may be provided with a plurality of slots (402-1, 402-2, 402-3) along width of the flap (202). The plurality of slots (402-1, 402-2, 402-3) is discontinuous with respect to one another and improves strength of the flap (202) provided. The plurality of slots (402-1, 402-2, 402-3) also defines a pocket structure as formed by the at least one slot (302) and guide the splashed oil from top surface of the flap (202) suitably in the same manner.
[0044] In an aspect, as shown in Figure 5 (500), the flap (202) is provided with at least one slot (302) adjacent to the bent edge (208). The at least one slot (302) may be a longitudinal slot provided along width of the flap (202). Herein, the at least one slot (302) is provided with a flange (501) protruded vertically upward from the top surface of the flap (202) to define an impediment which is able to guide the splashed oil reaching on top surface of the flap (202) to the oil gutter (102). Eventually, this arrangement prevents wastage of splashed oil from the top surface of the flap (202) and also lubricates remote transmission part through the guided arrangement.
[0045] Figures 6 (a)-(c) (600) illustrate a comparison between the existing arrangement and the present arrangement of the gutter assembly (300) in accordance with an embodiment of the present disclosure. It may be observed from Figure 6 (a), that in the existing arrangement, as shown by hollow circular patterns, the splashed oil (604) being thrown towards the flap (202) gets directed towards the oil gutter (102), however a part of the splashed oil (604) gets onto the top surface of the flap (202) gets diverted (602) i.e. as shown by filled circular patterns, thereby cannot be directed towards the oil gutter (102), hence getting wasted due to occurrence of an in-efficient lubrication of the remote transmission parts. On the other hand, as shown in Figure 6 (b), the splashed oil (608) reaching top surface of the flap (202) is collected (606) through the at least one slot (302) or by the plurality of slots (402-1, 402-2, 402-3) or by the upward projected vertical flange (501) and gets directed in a well-defined manner towards the oil gutter (102). Therefore, as shown in Figure 6 (c), the splashed oil from the top surface of the flap (202) is efficiently guided (610) through the oil gutter (102) for lubrication purpose.
[0046] Therefore, in this manner, the present structure (300) helps is reducing wastage of the lubricating oil and also provides lubrication of remote transmission parts in an efficient manner.

All in all, the invention described in the present disclosure is having the following advantages:
a) The present structure (300) proposes a cost-effective solution for improvement of lubrication of remote areas of the transmission
b) The present structure (300) allows efficient utilization of splashed oil that is flowing to top surface of the flap (202) and is eventually wasted
c) The present structure (300) improves efficiency of transmission of the vehicle
d) The present structure (300) is rigid and compact
e) The present structure (300) can be implemented in any type of transmission/systems (namely manual transmission, automatic manual transmission, automatic transmission, transmission with built-in motor, etc.) where lubrication is done by splashed oil

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.”
[0051] It will be further appreciated that functions or structures of a plurality of components or steps may be combined into a single component or step, or the functions or structures of one-step or component may be split among plural steps or components.
