DETAILED DESCRIPTION
[0027] A few aspects of the present disclosure are explained in detail below with reference to the various figures. Example implementations are described to illustrate the disclosed subject matter, not to limit its scope, which is defined by the claims. Those of ordinary skill in the art will recognize a number of equivalent variations of the various features provided in the description that follows.
[0028] 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 alternatives falling within the scope of the disclosure.
[0029] 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.
[0030] The present disclosure is related to a transmission assembly of a vehicle. The present disclosure particularly relates to an arrangement of the transmission assembly, where a protective structure is present and is configured to protect a transmission case against damage during impact, specifically during frontal impact of the vehicle where the transmission case hits with stiffened surrounding parts made up of sheet metal or like materials. The salient features of the present invention are discussed in detailed manner in the subsequent sections.
[0031] Figure 1 (a-b) depicts a transmission assembly (100) of a vehicle in accordance with an embodiment of the present disclosure. It may be observed from the figure that the transmission assembly (100) is comprising of a transmission case (102), a transmission unit (101) and a protective bracket (104).
[0032] In an aspect, the protective bracket (104) is coupled with the joinery of the transmission case (102) and the transmission unit (101).
[0033] Referring to Figure 2 (a-c), it may be witnessed that the protective bracket (104) is having a curved profile. Further, the protective bracket (104) comprises of an elongated vertical wall (106), at least two mounting regions (108) and a horizontal wall (112).
[0034] In an aspect, the elongated vertical wall (106) is positioned perpendicular to the transmission case (102). Moreover, the elongated vertical wall (106) is having a first portion (106-1), a second portion (106-2) and a third portion (106-3), respectively.
[0035] In an aspect, the at least two mounting regions (108) extend perpendicularly from longitudinal edges (114) of the first portion (106-1) and the third portion (106-3), respectively. The at least two mounting regions (108) are extending towards the transmission case (102) and are configured to facilitate coupling of the elongated vertical wall (106) to the transmission case (102) by fastening.
[0036] In an aspect, the horizontal wall (112) is extending perpendicularly from opposite longitudinal edge (116) of the second portion (106-2) of the elongated vertical wall (106) and is configured to extend over at least a portion of the transmission case (102).
[0037] In an aspect, as can be observed from Figure 2 (a), the first portion (106-1) and the third portion (106-3) of the elongated vertical wall (106) comprises of one or more ribs (110) defined along width of the elongated vertical wall (106). Herein, each one or more ribs (110) are extending towards the at least two mounting regions (108) and are configured for stiffening the protective bracket (104).
[0038] In an embodiment, the protective bracket (104) follows curved profile of the transmission assembly (100).
[0039] However, in another embodiment, shape of the protective bracket (104) may not follow profile of the transmission assembly (100). Herein, profile of the protective bracket (104) may be straight, or may be of any other shape as may be obvious to a person skilled in the art.
[0040] In an aspect, it may be noted that in existing arrangements i.e., without the presence of any protecting brackets or like structures, there is a possibility of electrical hazard when the transmission case (102) comes in contact with rigid part of the vehicle and gets damaged in an event of frontal impact.
[0041] In an aspect, on the other hand when the transmission assembly (100) is coupled with the protective bracket (104) as disclosed in the present subject matter, the protective bracket (104) prevents any direct contact of the transmission case (102) with the rigid part of the vehicle, thereby preventing any subsequent damage to the transmission case. As a result, the possibility of electrical hazard is prevented.
[0042] In this manner, the transmission assembly (100), especially the protective bracket (104) disclosed in the present invention protects the transmission case (102) against damage in the event of impacts by the vehicle.
[0043] Technical Advantages
[0044] All in all, the present invention has the following advantages:
i) Protects the transmission case from damages caused otherwise due to impact
ii) Prevents accident otherwise resulting due to electrification in the existing arrangement
iii) The protective bracket disclosed in the present invention is rigid and robust
[0045] Equivalents
[0046] It should be noted that the description and figures merely illustrate the principles of the present subject matter. It should be appreciated by those skilled in the art that conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present subject matter. It should also be appreciated by those skilled in the art that by devising various systems that, although not explicitly described or shown herein, embody the principles of the present subject matter and are included within its spirit and scope. Furthermore, all examples recited herein are principally intended expressly to be for pedagogical purposes to aid the reader in understanding the principles of the present subject matter and the concepts contributed by the inventor(s) to furthering the art and are to be construed as being without limitation to such specifically recited examples and conditions. The novel features which are believed to be characteristic of the present subject matter, both as to its organization and method of operation, together with further objects and advantages will be better understood from the above-mentioned description when considered in connection with the accompanying figures.
[0047] Although embodiments for the present subject matter have been described in language specific to package features, it is to be understood that the present subject matter is not necessarily limited to the specific features described. Rather, the specific features and methods are disclosed as embodiments for the present subject matter. Numerous modifications and adaptations of the system/device of the present invention will be apparent to those skilled in the art, and thus it is intended by the appended claims to cover all such modifications and adaptations which fall within the scope of the present subject matter.
[0048] 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.”
[0049] 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. The present invention contemplates all these combinations. Unless stated otherwise, dimensions and geometries of the various structures depicted herein are not intended to be restrictive of the invention, and other dimensions or geometries are possible. In addition, while a feature of the present invention may have been described in the context of only one of the illustrated embodiments, such feature may be combined with one or more other features of other embodiments, for any given application. It will also be appreciated from the above that the fabrication of the unique structures herein and the operation thereof also constitute methods in accordance with the present invention. The present invention also encompasses intermediate and end products resulting from the practice of the methods herein. The use of “comprising” or “including” also contemplates embodiments that “consist essentially of” or “consist of” the recited feature.
