CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
[001] The present invention claims priority from Indian patent application numbered IN 202241053980 filed on 21st September, 2022.
FIELD OF THE INVENTION
[002] The present subject matter described herein generally relates to an integral bracket assembly for direct coupling of an engine and transmission, and more specifically for an integral bracket assembly for direct coupling of an engine and transmission in mining equipment’s.
BACKGROUND
[003] To mount the accessories to the engine block or transmission block or chassis, a set of accessory mounting brackets for each type of accessory is used to mount the accessories to the engine block or transmission block or chassis. Mounting brackets are hardware products and designed to hold items together mostly at a right angle to each other. They are available in different shapes and sizes depending on where they are mounted and the objects they hold together. The bracket can be threaded or non-threaded, hinged, or a mounting block with the shape being a short L, tall L, straight, block, or Z shaped. Brackets are made of aluminum, brass, nylon, polypropylene, or steel. Steel brackets can sufficiently bear the weight of heavy objects that are mounted.
[004] At present there are individual brackets available for the engine and the transmission with another additional bracket to connect the engine and the transmission on to the main frame. Such that three brackets are used in total on each side to mount the engine and the transmission directly coupled on to the mainframe of a mining equipment. The adoption of a plurality of accessory mounting brackets not only increases the production cost of the mounting brackets, but also causes the volume of the engine system to be larger and the structure to be more complicated. The use of multiple brackets increases the risk of misalignment.
[005] Hence to overcome the aforesaid drawbacks there is a requirement to design a novel integral bracket.

OBJECTS OF THE INVENTION
[006] Main object of the present disclosure is to provide an integral bracket assembly for direct coupling of an engine and transmission to mount the engine, the transmission on the mainframe with one single bracket on each side.
[007] Another object of the present disclosure is to provide an integral bracket assembly for direct coupling of an engine and transmission to minimize the difficulty to mount the engine and the transmission on to the mainframe.
[008] Yet another object of the present disclosure is to provide an integral bracket assembly for direct coupling of an engine and transmission to reduce the assembly time.
[009] Another object of the present disclosure is to provide an integral bracket for assembly direct coupling of an engine and transmission to reduce the effort required for mounting the engine and the transmission on to the mainframe.
[0010] Yet another object of the present disclosure is to provide an integral bracket assembly for direct coupling of an engine and transmission to reduce the raw material required for the brackets.
[0011] Another object of the present disclosure is to provide an integral bracket assembly for direct coupling of an engine and transmission such that the skill required to mount the integral bracket is minimum.
[0012] Yet another object of the present disclosure is to provide an integral bracket assembly for direct coupling of an engine and transmission to reduce the number of fasteners.
[0013] Another object of the present disclosure is to provide an integral bracket assembly for direct coupling of an engine and transmission to all mining equipment such that they are retrofitted with integral bracket.
[0014] Yet another object of the present disclosure is to provide an integral bracket assembly for direct coupling of an engine and transmission to eliminate the mismatch of holes pitch due to weld distortion.
[0015] Another object of the present disclosure is to provide an integral bracket assembly for direct coupling of an engine and transmission which is compact, cost effective and easy to implement.

Equivalents
[0053] 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.
[0054] 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."
[0055] Although implementations for the integral bracket assembly for direct coupling of an engine and transmission have been described in language specific to structural features and/or methods, it is to be understood that the appended claims are not necessarily limited to the specific features described. Rather, the specific features are disclosed as examples of implementation for the integral bracket assembly for direct coupling of an engine and transmission.
