The vehicles are utilized for various purposes including transportation of raw materials, as means of convenience for travelling from one place to another and likewise. The vehicles, preferably two-wheelers, has shown an immense growth in last couple of years. The increase in vehicle numbers has led researchers to improve the different parameters of the vehicles for example - efficiency of the vehicle, strength of the vehicle, comfort to a rider as well as to passengers and likewise. One of the ways, to improve the comfort for the rider/passengers without compromising strength of the vehicle, is to employ suspension systems to the vehicle.
[005] According to the known background art, a vehicle suspension comprises two shock absorbers mounted on front wheel of the vehicle and one or two shock absorbers mounted on rear wheel of the vehicle. Conventionally, the frame structure or body frame of a vehicle, extends rearwardly from the vehicle's head pipe. The frame structure of the vehicle is configured to mount suspension systems of the vehicle, which are shock absorbers.
[006] Now-a-days, a single suspension system are manufactured and assembled to the two-wheelers. A mounting of an existing single suspension system is disclosed in FIG. 1. FIG. 1 depicts an existing frame of a vehicle, utilized for mounting the single shock absorbed at the center portion of the vehicle. The frame (1) comprises a first cross member (2) and a second cross member (3) to provide provision for mounting a bracket (4). The first cross member (2) and the second cross member (3) are positioned at two different locations in the frame (1) of the vehicle, such that the two cross members (2, 3) are connected to two side members (6, 7) of the frame (1). Further, the first cross member (2) and the second cross member (3) are spaced apart from each other. The bracket (4) is connected to two cross members (2, 3). The shock absorber is configured to mount on the bracket (4). Further, two more brackets (5) are fixed at ends of the second cross member (3) connecting the second cross
member (3) with the respective side members (6, 7). The first cross member (2) and the second cross member (3) mounted in a spaced apart configuration from each other requires more packaging space of the vehicle, which in turn hinders mounting of other components of the vehicle. The mounting of shock absorber on the bracket (4) may not possess effective load transfer capability.

The primary bracket (203) is mounted on one of the first cross member (201) and the second cross member (202) or on said junction of the first cross member (201) and the second cross member (202). In an exemplary embodiment, the primary bracket (203) is mounted on the junction of the first cross member (201) and the second cross member (202). The primary bracket (203) extends rearwardly from the first cross member (201) and the intermediate portion (202c) of the second cross member (202). The primary bracket (203) facilitates connecting a first end (204a) of a shock absorber (204) of the suspension mounting assembly (200), with the first cross member (201) and the second cross member (202) of the suspension mounting assembly (200)
of the vehicle (100), as shown in FIGS. 4-12. The first end (204a) of the shock absorber (204) is connected to the primary bracket (203) by means of fasteners (205). The primary bracket (203) is configured to uniformly transmit force or load generated due to shocks and/or jerks from the shock absorber (204) to the first cross member (201) and the second cross member (202). The uniform transmission of load to the first cross member (201) and the second cross member (202) provides comfort to the rider while driving the vehicle (100).
[067] Referring to FIGS. 4-6, the vehicle (100) comprises the pivot element (113f) and the pivotal arm (113g), to facilitate mounting of a second end (204b) of the shock absorber (204). The pivot element (113f) is defined having a trigonal structure, such that each end of the trigonal structure is having a hole to facilitate mounting of the pivot element (113f) on to the main frame (113) of the vehicle (100). A one end of the pivot element (113f) is pivotably mounted to the swing arm (113h) at the rear portion (113c) of the main frame (113) of the vehicle (100), by means of fasteners. Another end of the pivot element (113f) is configured to pivotably mount the second end (204b) of the shock absorber (204) and remaining end of the pivot element (113f) is configured to pivotably mount the pivotal arm (113g). The pivotal arm (113g) is pivotably mounted at the center portion (113b) of the mainframe (113) of the vehicle (100). One end of the swing arm (113h) is connected to the rear wheel (115) of the vehicle (100) and another end is connected to the main frame (113) of the vehicle (100) through the swing arm bracket (113i). The swing arm (113h) is pivotably connected to the swing arm bracket (113i) by means of fasteners. The swing arm (113h) possesses swinging and/or pivotal movement about the swing arm bracket (113i) during shocks and/or jerks on the vehicle (100), which in turn governs pivotal movement of the pivot element (113f) about the respective ends of the pivot element (113f). The pivotal movement of the pivot element (113f) facilitate pivotal movement of the shock absorber (204), to absorb shock and/or jerks on the vehicle (100). The shock absorber (204) may be defined as a spring, hydraulic or pneumatic shock absorber, but not limited to the same. In an exemplary embodiment, the shock absorber (204) is defined to be a spring type shock absorber, as shown in FIG. 4. Alternatively, the second end (204b) of the shock absorber (204) may be directly connected to the rear portion (113c) of the main frame (113) of the vehicle (100).
[068] In another exemplary embodiment, the intermediate portion (202c) of the second cross member (202) and the first cross member (201) provide provision for mounting a secondary bracket (206) to facilitate mounting of the engine (119) to the main frame (113) of the vehicle (100), as shown in FIG. 4, FIG. 6 and FIG. 7. The secondary bracket (206) extends from the first cross member (201) and the intermediate portion (202c) of the second cross member (202), in a diagonally opposite direction
to the primary bracket (203). The secondary bracket (206) may be defined to extend towards the front body structure (101) of the vehicle (100), as shown in FIG. 9 and FIG. 10. The primary bracket (203) and the secondary bracket (206) are connected to the first cross member (201) and the intermediate portion (202c) of the second cross member (202) by conventional connecting means, preferably through welding. The secondary bracket (206) extending from the first cross member (201) and the intermediate portion (202c) of the second cross member (202), utilizes less packaging space for mounting the engine (119) on the main frame (113) of the vehicle (100).
[069] The engine (119) is mounted on the main frame (113) of the vehicle (100) through the secondary bracket (206), by means of fasteners. The positioning and arrangement of the first cross member (201) and the second cross member (202) on the main frame (113), facilitates integral mounting of the engine (119) and the shock absorber (204). The first cross member (201) and the second cross member (202) may be configured to provide provision for mounting more than one shock absorber (204). The first cross member (201) and the second cross member (202) positioned between the two longitudinal members (113d, 113e) of the main frame (113) provides strength and rigidity to the main frame (113) of the vehicle (100).

Therefore, it is intended that the present disclosure covers such modifications and variations provided they come within the ambit of the appended claims and their equivalents.
[078] Equivalents:
[079] 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.
[080] 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." While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
