TECHNICAL FIELD
Present disclosure relates to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to mounting structures for a vehicle. Further, embodiments of the present disclosure relate to a mount element for connecting a heavy weight powertrain on a frame of a vehicle.
BACKGROUND OF THE DISCLOSURE
Generally, vehicles include a number of components (also referred to as driving and driven components) such as motors, pumps, engine, gearbox, clutches and the like, which may generate noise and vibrations during operation or during engagement with other components, which causes inconvenience to operator inside the vehicle.
Conventionally, such components, in particular, powertrain or the powertrain components, are coupled to the frame or chassis of the vehicle through mounting elements. Such mounting elements are designed to couple the powertrain with the frame of the vehicle. The mounting elements also absorb vibrations generated by the powertrain. Generally, the mounting elements include a rubber padding accommodated on the frame or chassis, which is configured to absorb and reduce vibrations from being transmitted to a cabin of the vehicle.
The above-described conventional mountings for connecting the powertrain and the frame of the vehicle may isolate noise and vibrations to a limited extent. However, a significant amount of noise and vibrations are transmitted to the cabin and other components in the vehicle. Further, conventional mounts may not dampen vibrations effectively and may not suppress vibrations generated in different directions due to structure and configuration of conventional mounts which are located to suppress vibrations or noise along one of X, Y and Z axis. Further, stiffness ratio of the conventional mounts for suppressing vibrations or noise along the X, Y and Z axis of such mount are often the same. Consequently, intensity of vibrations suppressed may be limited as the mounts may undergo limited displacement, which may not be undesired.
Furthermore, ability of the conventional mounts to dampen noise, vibrations and support the powertrain often reduces as weight of the powertrain increases. Consequently, mounts of larger size may be required, which may reduce available space for the components of the powertrain. Additionally, the conventional mounts may not offer required support and also fail to effectively dampen vibrations in multiple directions.

The present disclosure is directed at overcoming one or more limitations stated above or any other limitations associated with the conventional arrangements.

One skilled in the art would appreciate the component disclosed in the claims, maybe any component which may be used in any given system but not limiting to vehicle and the like.
Figure 1 and Figure 2 illustrate an engine bay (200) of a vehicle. The engine bay (200) may include a frame (8). The frame (8) may accommodate a powertrain (9) of the vehicle. The powertrain (9) may be mounted to the frame (8) by a plurality of mount elements (100) [hereinafter interchangeably referred to as “the mount (100)”]. Further, one end of the mount (100) may be coupled to the powertrain (9) and an opposite end of the mount (100) may be coupled to the frame (8). Further, as the vehicle is traversed over a path, undulations or un¬even surfaces of that path may often induce vibrations onto the frame (8) of the vehicle which may further be transmitted to the powertrain (9) of the vehicle. The vibrations from the powertrain (9) may be in a clockwise direction or along an anti-clockwise direction. The mount (100) of the present disclosure is configured to couple and support heavy weight powertrains (9) on the frame (8). The mount (100) may also be configured to absorb or dampen vibrations from the powertrain (9) and may prevent or reduce the vibrations from the powertrain (9) to the frame (8) of the vehicle. In an embodiment, the positioning of the mount (100) must not be limited to connecting the powertrain (9) and the frame (8) and the mount (100) may be configured to receive other components that induce vibrations including but not limited to motors, pumps, engine, gears of gearbox, clutch etc.
Reference is now made to Figure 3 and Figure 4 which illustrates the mount (100). The mount (100) may include a body (4). The body (4) may be defined by a first end (4a) and a second end (4b). The first end (4a) of the body (4) may be defined by an inverted conical profile and the second end (4b) of the body (4) may be defined with a cylindrical shaped profile. Further, the first end (4a) of the body (4) may be defined with at least one aperture (4x) that is configured to receive a fastener (6). Furthermore, the body (4) may be an elongated structure defined with a central hole (4h). The central hole (4h) may be a through hole that extends along the length

of the body (4). The central hole (4h) may extend along a first axis (Z-Z) of the body (4) which extends in a vertical direction of the body (4).
The mount (100) may include a first plate (1) positioned on the first end (4a) of the body (4). The first plate (1) may be aligned to extend along a second axis (Y-Y) of the body (4). The first plate (1) is connectable with the first end (4a) of the body (4). The first plate (1) may be removably connected to the first end (4a) of the body (4) by fasteners (6). The fasteners (6) may be configured to extend through the first plate (1) and into the first end (4a) of the body (4) to connect the first plate (1) with the body (4). In an embodiment, the first plate (1) may be coupled to the body (4) by any means including but not limited to welding, brazing, and any other means of connecting.
Further, the mount (100) may include a second plate (2). In the illustrative embodiment, the second plate (2) may be defined as a U-shaped structure, however such profile of the second plate (2) shall not be considered as a limitation, as any profile providing similar structure and function may be employable in the mount. The second plate (2) with the U-shaped structure may be defined with a top end (2a) and a bottom end (2b). The U-shaped structure of the second plate (2) may be defined with a hole such that the bottom end (2b) of the U-shaped structure remains open or the bottom end (2b) of the second plate is defined with a hole. The diameter of the hole at the bottom end (2b) of the second plate (2) may be significantly greater than the diameter of the body (2). Further, the second plate (2) may be defined with an inclined profile which extends along the bottom end (2b) of the body (2). The U-shaped structure of the second plate (2) may include a flange (2f). The top end (2a) of the second plate (2) may be defined with the flange (2f) and the flange (2f) may extend outwardly from the top end (2a) of the second plate (2). Further, the flange (2f) at the top end (2a) of the second plate (2) may extend away from the first axis (Z-Z) and may extend along the second axis (Y-Y). The second plate (2) may be positioned around the body (4) and the body (4) may extend through the hole defined at the bottom end (2b) of the second plate (2). The second plate (2) may be positioned coaxially around the body (4) such that the center of the hole defined at the bottom end (2b) of the second plate (2) is configured to lie on the first axis (Z-Z) of the mount (100). Further, the hole at the bottom end (2b) of the second plate (2) is at a pre-determined distance away from the body (2). Furthermore, the second plate (2) is oriented such that the bottom end (2b) lies proximal to the second end (4b) of the body (4) and at a pre-determined distance away from the second end (4b) of the body (4). The second plate (2) is oriented with respect to the body

(4) such that flange (2f) lies adjacent to the region where the inverted conical profile at the first end (4a) of the body (4) merges into a cylindrical profile of the body (4). The second plate (2) is oriented such that the flange (2f) extends in a direction that is parallel to the first plate (1) of the mount (100) and the flange (2f) is positioned at a pre-determined distance from the first plate (1).
The mount (100) includes a dampener (5). As seen from the Figure 4, the dampener (5) may include a first section (5f) and a second section (5s). The first section (5f) and the second section (5s) are defined as a unitary component which together define the dampener (5). The first section (5f) and the second section (5s) being a unitary component must not be considered as a limitation and the dampener (5) may be configured with multiple sections that are independent of each other or are positioned adjacent to each other. Further, the overall profile of the first section (5f) may be of conical shape and the profile of the second section (5s) of the dampener (5) may be of a rectangular shape. Further, the inclination of the conical shape on the first section (5f) of the dampener (5) may be for a distance that is equivalent to the distance between the first plate (1) and the flange (2f) of the second plate (2). The dampener (5) may be defined with a first cutout (5a). The first cutout (5a) may be of any shape including but not limited to a conical shape. Thes first cutout (5a) may be defined along the region of the dampener (5) where the first section (5f) merges with the second section (5s) of the dampener (5). The conical shaped first cutout (5a) may extend coaxial around the first section (5f) of the dampener (5). The first cutout (5a) may offer the required stiffness for the movement of the dampener (5) along the second axis (Y-Y). The first cutout (5a) may offer the required stiffness for the movement of the dampener (5) along a third axis (X-X) of the mount (100) which extends in a direction perpendicular to the first axis (Z-Z) and the second axis (Y-Y) of the mount (100). The depth of the first cutout (5a) may be inversely proportional to the stiffness offered by the mount (100). In an exemplary embodiment, the first cutout (5a) with increased depth may offer lesser stiffness and may allow the dampener (5) to be moved excessively whereas the first cutout (5a) with lesser depth may offer higher stiffness and may restrict the movement of the dampener (5). The dampener (5) may be defined with a second cutout (5b). The second cutout (5b) may be defined with an inverted conical profile and the second cutout (5b) may be configured to extend from a bottom end of the dampener (5) to a substantially middle section of the dampener (5). The width of the second cutout (5b) may be defined to be equivalent to the distance between the bottom end (2b) of the second plate (2) and the body (4) of the mount (100). Further, the conical shaped second cutout (5b) may extend coaxial inside
8

the first section (5f) of the dampener (5). The second cutout (5b) may offer the required stiffness for the movement of the dampener (5) along the second axis (Y-Y) and the third axis (X-X) of the mount (100). The depth of the second cutout (5b) may be inversely proportional to the stiffness offered by the mount (100). In an exemplary embodiment, the second cutout (5b) with increased depth may offer lesser stiffness and may allow the dampener (5) to be moved excessively whereas the second cutout (5b) with lesser depth may offer higher stiffness and may restrict the movement of the dampener (5). The first cutout (5a) and the second cutout (5b) may allow the movement of the dampener (5) along the second axis (Y-Y) and the third axis (X-X). Consequently, the first cutout (5a) and the second cutout (5b) may effectively dampen the vibrations from the powertrain (9) of the vehicle. In an embodiment the second cutout (5b) may act as a stopper and may restrict the movement of the dampener (5) along the second axis (Y-Y). The dampener may be of any material including but not limited to rubber which may effectively dampen noise and vibrations.
As seen from the Figure 4, the dampener (5) may be accommodated by the second plate (2). The dampener (5) may be positioned on the U-shaped structure and the flange (2f) of the second plate (2). The first section (5f) of the dampener (5) may be accommodated on the U-shaped structure of the second plate (2) and the second section (5s) may be accommodated on the flange (2f) of the second plate (2). The central region of the first section (5f) of the dampener (5) may abut the body (4) of the mount (100). The dampener (5) is positioned on the second plate (2) such that the second cutout (5b) at the bottom end of the first section (5f), extends between the bottom end (2b) of the second plate (2) and the body (4).
The mount (100) may include a third plate (3). The third plate (3) may be a plate with a circular profile and a hole defined at the center. The diameter of the hole defined on the third plate (3) may be equivalent to the diameter of the central hole (4f) defined to the body (4). The third plate (3) may be positioned to abut the second end (4b) of the body (4) and the third plate (3) is positioned at a pre-determined distance away from the bottom end (2b) of the second plate (2). The third plate (3) may be oriented such that the central point of the hole defined on the third plate (3) lies along the first axis (Z-Z) of the mount (100). Further, the central hole (4h) of the body (4) and the hole defined to the third plate (3) may lie adjacent to each other and may lie along the same first axis (Z-Z). The third plate (3) may be fixedly coupled to the body (4) by a fastener (6) which extends through the hole defined to the third plate (3) and the central hole (4h) of the body (4). The mount (100) may include a stopper (7). The stopper (7) may be

made of the same material as the dampener (5). The stopper may be positioned on the third plate (3) and the stopper (7) may be configured to lie proximal or below the bottom end (2b) of the second plate. The third plate (3) and the stopper (7) are oriented such that a pre¬determined distance is defined between the bottom end (2b) of the second plate (2) and the stopper (7).
The powertrain (9) of the vehicle may be positioned on the first plate (1) of the mount (100) and the powertrain (9) may be fixedly coupled with the mount (100) by means of a bolt (10). The bolt (10) may extend from the powertrain (9) and through the first plate (1) into the central hole (4h) of the body (4) for fixedly coupling the powertrain (9) with the mount (100). The flange (2f) of the second plate (2) may be fixedly coupled to the frame (8) of the vehicle by any means including but not limited to fasteners.
The first cutout (5a) and the second cutout (5b) of the dampener (5) may be configured to offer varying stiffness to the dampener (5) for displacement or movement of the dampener in the second axis (Y-Y) and the third axis (X-X). Thus, the first cutout (5a) and the second cutout (5b) may be configured to dampen the vibrations by absorbing the same which are induced along the second axis (Y-Y) and the third axis (X-X). Further, the vibrations which are induced along the first axis (Z-Z) are also dampened by the mount (100). The first plate (1) may be configured to traverse along the first axis (Z-Z) and the first plate (1) may be configured to come in contact with the second section (5s) of the dampener (5) when vibrations are induced along the first axis (Z-Z). The second section (5s) of the dampener (5) may absorb and thereby dampen the vibrations that are induced along the first axis (Z-Z). The first plate (1) along with the body (4) may move downwardly along the first axis (Z-Z) and the first plate (1) may initially come in contact with the second section (5s) of the dampener (5). The first plate (1) may further traverse downwardly when the vibrations are high along the first axis (Z-Z). Consequently, the first plate (1) traverses downwardly along with the dampener (5) and the second plate (2) onto the stopper (7) of the third plate (3). The bottom end (2b) of the second plate comes in contact with the stopper (7) and the stopper (7) further absorbs or dampens the vibrations along the first axis (Z-Z). The second section (5s) of the dampener (5) and the stopper (7) on the third plate (3) may effectively dampen the vibrations along the first axis (A-A). The above configuration of the mount (100) with the dampeners (5) provides the required stiffness along the first axis (Z-Z), the second axis (Y-Y), and the third axis (X-X) and also offers low dynamic stiffness factor. In an embodiment, the configuration of the dampener (5)

with the first cut out (5a) and the second cutout (5b) may enable the provision of varying stiffness along different directions i.e., varying stiffness along the first axis (Z-Z), the second axis (Y-Y), and the third axis (X-X). In an embodiment, the configuration of the mount (100) provides a compact and low weight structure for connecting the powertrain (9) with the frame (8) of the vehicle. The above configuration of the mount (100) is suitable for connecting heavy weight powertrains (9) with the frame (8) of the vehicle.
Equivalents
With respect to the use of substantially any plural and/or singular terms, 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 for sake of clarity.
It will be understood by those within the art that, in general, terms used, 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 description 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,
11

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, 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."
While various aspects and embodiments have been disclosed, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated in the description.
