The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
[001].Present disclosure in general relates to the field of automobiles. Particularly, but not exclusively, the disclosure relates to an axel assembly of a vehicle. Further, embodiments of the disclosure, relates to a mechanism for adjusting toe and camber of a wheel of a vehicle.
BACKGROUND OF THE DISCLOSURE
[002].Generally, parameters for controlling a vehicle such as, but not limited to, traction, velocity, suspension, center of gravity and other parameters that affect performance and movability of the vehicle may be regulated by adjusting extent of contact between tires of the vehicle relative to a terrain. Some of such parameters are toe angle, caster, and camber of the wheels of the vehicle, which affect mobility and nature of movement of the vehicle. By adjusting such parameters, factors such as, cornering, shock absorption, weight distribution and the like, may be controlled for handling of the vehicle. Also, such parameters improve durability of components in an axle assembly, the tires, and the like of the vehicle, by reducing wear and tear due to frictional engagement.
[003].Conventionally, abovesaid parameters of the vehicle may be adjusted by modifying either configuration of a steering system or a suspension system in the vehicle, so that an operator or driver may be equipped for better handling of the vehicle. With advent of technology, modification of said parameters have been performed by varying configuration of components of the axle assembly. In some conventional axel assemblies, configuration of a knuckle is modified for varying camber or toe angles of the wheel, however, such modification may require corresponding alterations and variations to be made for other components of the axle assembly, which may render such variation to be expensive. On the other hand, in other conventional axle assemblies, a base plate being connected to the knuckle may be modified for adjusting camber or toe angles. Such modification to the base plate may be performed by varying at least one of thickness, curvature, and/or aerofoil profile of said base plate. For performing such modifications to the base plate may increase turning radius for the knuckle to be adjusted, however, such modification may require separate die for forming said base plate or sophisticated machine to perform such structural variations. Such requirements may increase costs associated with manufacturing components and in-turn cost of the axel assembly of the vehicle.

[004].Moreover, in some of conventional axle assemblies, configuration of the base plate and the knuckle have been fixed by machining the base plate to define toe and camber values, i.e., restrictive to preforming variations to camber or toe angles. Such configuration of fixed camber and toe angles may be lead to increase in wear and tear of tires, which may in turn increase operation costs of the vehicle.
[005].The present disclosure is directed to overcome one or more limitations stated above or any other limitation associated with the conventional arts.

DETAILED DESCRIPTION
[0024].While the embodiments in the disclosure are subject to various modifications and alternative forms, specific embodiment thereof has 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.
[0025].The terms “comprises”, “comprising”, or any other variations thereof used in the disclosure, are intended to cover a non-exclusive inclusion, such that a mechanism, and an 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. In other words, one or more elements in an assembly or a system proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the assembly.
[0026].Embodiments of the disclosure are described in the following paragraphs with reference to Figures 1 and 7. In the figures, the same element or elements which have same functions are indicated by the same reference signs. It is to be noted that, the vehicle is not illustrated in the figures for the purpose of simplicity. One skilled in the art would appreciate that the mechanism as disclosed in the present disclosure can be used in any vehicle including, but not liming to, passenger cars, heavy motor vehicles, light motor vehicles or any other vehicle.
[0027].Figure 1 is an exemplary embodiment depicting segment of an axle assembly (101) for a wheel (102) of a vehicle. The axle assembly (101) includes at least one axle (101a) which is configured to support at least one wheel (102) of the vehicle, along with other components and/or sub-assemblies such as suspension mechanism (100), braking mechanism (100), and/or steering mechanism (100) [not illustrated for simplicity of explanation of the mechanism (100)]. In the illustrative embodiment, the axel (101a) is a rear twist beam or axle (101a), which is configured to support the suspension mechanism (100) and the braking mechanism (100) along with at least one wheel (102) at rear portion of the vehicle. The axle assembly (101) includes a mechanism (100) for adjusting various manoeuvring parameters of the vehicle. Some of such parameters may be including camber and toe angles of the at least one wheel (102) [hereinafter interchangeably referred to as “wheel (102)”] for varying structural configuration such as, orientation of the wheel (102) relative to a terrain, area of contact of the wheel (102) with the terrain, turning and/or cornering radius, turning speed, and the like.
[0028].Referring now to Figures 2 to 4, which depict the mechanism (100) being coupled to the axle (101a) of the axle assembly (101). For sake of explanation, the wheel (102) has not been illustrated to be coupled to the axle assembly (101), while it should be construed that the mechanism (100) is operable to selectively operate and/or regulate operation of the wheel (102). The mechanism (100) is included and/or coupled at an end or proximal to the end of the axle (101a), in order to selectively connect with the wheel (102). At least a portion of the mechanism (100) is directly coupled to the axle (101a), as best seen in Figures 2 and 3, while an other portion of the mechanism (100) is directly and movably connected to the wheel

(102), as best seen in Figure 1. Such connection of the mechanism (100) between the axel (101a) and the wheel (102) may allow modification to be performed to such connection to the wheel (102) for adjusting, improving and/or enhancing handling of the vehicle during motion. Based on top view of the axle assembly (101) and the mechanism (100) as seen in Figure 2, in general, the mechanism (100) is aligned along a first reference axis (H-H), and at least portion of the mechanism (100) may be adjusted relative to the first reference axis (H-H) based on requirement. In similar manner, side view of the axle assembly (101) and the mechanism (100) as seen in Figure 3, in general, the mechanism (100) is aligned along a second reference axis (I-I), and at least portion of the mechanism (100) may be adjusted relative to the second reference axis (H-H) based on requirement. In an embodiment, adjustment of the mechanism (100) relative to the first reference axis (H-H) may be construed for toe angle adjustment [hereinafter interchangeably referred to as “toe adjustment”], and adjustment of the mechanism (100) relative to the second reference axis (I-I) may be construed for camber angle adjustment [hereinafter interchangeably referred to as “camber adjustment”].
[0029].Referring to Figures 2 and 3 in conjunction with Figure 4, the mechanism (100) includes a base plate (1), a bracket (2) and a knuckle plate (3). As seen in Figures 2 and 3, the base plate (1) of the mechanism (100) is rigidly coupled to an end or proximal to the end of the axle (101a) of the axle assembly (101). In an embodiment, the base plate (1) may be directly coupled to the axel (101a) or may be rigidly coupled to a frame [not seen in Figures] which may be detachably coupled to the axle (101a). In an embodiment, the base plate (1) may be connected to the axel (101a) by any configuration in which the base plate (1) may be maintained stationary relative to the axle (101a). In the illustrative embodiment, the base plate (1) is rigidly connected to an end of the axle (101a) by way of connecting means such as, but not limited to, welding, brazing, riveting, and the like. The bracket (2) of the mechanism (100) is detachably connected to the base plate (1) and positioned away from the axle (101a) of the vehicle. Also, the knuckle plate (3) of the mechanism (100) is connectable to the bracket (2) and position away from the base plate (1). As best seen in Figures 1-3, the knuckle plate (3) includes a projecting member (8) which is connectable to the wheel (102) of the vehicle and may selectively be adjusted in order to vary orientation of the wheel (102) relative to at least one of the first reference axis and the second reference axis (i.e., in a horizontal and/or vertical axis relative to the axle (101a) of the vehicle), to suitably

manoeuvre the vehicle and regulate operating conditions of the wheel (102), and in-turn that of the vehicle.
[0030].In an embodiment, the mechanism (100) may be accessible by an operator on removal of the wheel (102) in order to suitably adjust at least one of camber and toe of corresponding wheel (102) of the vehicle. In an embodiment, the first reference axis and the second reference axis should not be construed as fixed axis or standard axis, rather the first reference axis and the second reference axis are to be construed as imaginary axis which may be variable depending on various factors including, nature of wheel (102) drive of the vehicle, load carrying capacity, terrain on which the vehicle is to be operated, and the like. The first reference axis and the second reference axis have been defined for understanding working principle of the present disclosure and the same shall not be considered as a numerical limitation of the present disclosure.
[0031].Turning now to Figure 5, the bracket (2) is defined with a first pair of connecting portions (2a) and a second pair of connecting portions (2b), as seen in Figure 5. Each of the first pair of connecting portions (2a) are defined on two opposing sides of the bracket (2), and at least one of the the second pair of connecting portions (2b) is defined adjacent to at least one connecting portions (2a) of the first pair of connecting portions (2a). Such configuration of the bracket (2) may allow automatic assembly of the mechanism (100) in a manufacturing assembly line, to effortless connect the bracket (2) with each of the base plate (1) and the knuckle plate (3). In the illustrative embodiment, the first pair of connecting portions (2a) of the bracket (2) is connectable to the pair of first engaging portions (1a) of the base plate (1), and the second pair of connecting portions (2b) of the bracket (2) is connectable with a pair of second engaging portion (3a) of the knuckle plate (3), as can be seen in Figure 4. Such configuration of the bracket (2) may be configured to allow pivotal movement between the bracket (2) and the knuckle plate (3) relative to the base plate (1). In the illustrative embodiment, the base plate (1) being rigidly coupled to the axel (101a) may be considered stationary, while movement between the bracket (2) and the knuckle plate (3) may be selectively regulated for adjusting toe and camber of the wheel (102). i.e., as the knuckle plate (3) is connected to the bracket (2), configuration of the knuckle plate (3) such as orientation and positioning [for instance, angle and distance from the bracket (2)] may be regulated by either operating the knuckle plate (3) relative to the bracket (2), or by operating the bracket (2) relative to the base plate (1).

[0032].Referring again to Figure 5, the pair of first engaging portions (1a) of the base plate (1) may be configured to forwardly extend [i.e., in a direction towards the wheel (102) on connecting the mechanism (100) with the axle (101a)] from at least two opposing sides of the base plate (1). The pair of first engaging portions (1a) are depicted to extend from a central portion of a side of the base plate (1), while said pair of first engaging portions (1a) may extend from any portion of the side of the base plate (1). Further, complementary to the base plate (1), the knuckle plate (3) is defined with the second engaging portions (3a) in order to connect with the bracket (2) in such a way as to position the bracket (2) between the base plate (1) and the knuckle plate (3), as seen from Figures 4 and 5. In the illustrative embodiment, the second engaging portions (3a) of the knuckle plate (3) rearwardly extend [i.e., in a direction away from the wheel (102) on connecting the mechanism (100) with the axle (101a)] from at least two opposing sides of the knuckle plate (3). In an embodiment, the second engaging portions (3a) of the knuckle plate (3) and the first engaging portions (1a) of the base plate (1) are oriented along different planes and axes in order to allow selective pivotal movement of the bracket (2) relative to each of the base plate (1) and the knuckle plate (3). Due to such configuration, the bracket (2) may be pivotally displaceable relative to each of the base plate (1) and the knuckle plate (3) in order to selectively adjust toe and camber of the wheel (102) of the vehicle.
[0033].In an embodiment, the pair of first engaging portions (1a) of the base plate (1) and the pair of second engaging portions (3a) of the knuckle plate (3) are structured to be substantially parallel to each other, to suitably accommodate and connect with the bracket (2). The term ‘substantially’ refers to an alignment in which each of the pair of first engaging portions (1a) and the pair of second engaging portions (3a) may have marginal manufacturing tolerances of 0.5 to 4deg variation, however, such tolerance may not affect connection of the base plate (1) with the bracket (2), as illustrated in Figures 4 and 5.
[0034].In the illustrative embodiment, profile of the bracket (2) may be considered to be at least one of a square, a rhombus or a rectangular profile. Due to such configuration of the bracket (2), each of the first pair of connecting portions (2a) and the the second pair of connecting portions (2b) are defined on two opposing sides of the bracket (2), while at least one of the the second pair of connecting portions (2b) being adjacent to at least one connecting portions (2a) of the first pair of connecting portions (2a). Such configuration of the bracket (2) allows ease in handling and assembling with the base plate (1) and the knuckle plate (3). In an

embodiment, considering the bracket (2) to be rectangularly profiled and being defined with the first pair of connecting portions (2a) on one of two opposing sides, and the second pair of connecting portions (2b) being defined with on other two opposing sides. As illustrated in Figure 5, the first pair of connecting portions (2a) are oriented about a horizontal axis of the bracket (2), while the second pair of connecting portions (2b) are oriented about a vertical axis of the bracket (2). Due to such configuration, the bracket (2) is connectable with the base plate (1) along the horizontal axis, and that the knuckle plate (3) is connectable with the bracket (2) along the vertical axis. Due to such connection, the bracket (2) is pivotable along a vertical plane relative to the base plate (1), while the knuckle is pivotable relative to the bracket (2) along a horizontal plane.
[0035].Referring to Figures 5, 6 and 7, the base plate (1), the bracket (2) and the knuckle plate (3) are connected to each other by at least one of a first eccentric bolt (5a), a second eccentric bolt (5b) and a fastening element (4). As can be seen in Figure 5, the base plate (1) and the bracket (2) are connectable by the fastening element (4) at one of the pair of first engaging portions (1a) and the first pair of connecting portions (2a). Meanwhile, other of the pair of first engaging portions (1a) of the base plate (1) and the first pair of connecting portions (2a) of the bracket (2) is connected by the first eccentric bolt (5a), to selectively displace the bracket (2) relative to the base plate (1). Similarly, the knuckle plate (3) and the bracket (2) are connectable by the fastening element (4) at one of the pair of second engaging portions (3a) and the second pair of connecting portions (2b), while other of the pair of second engaging portions (3a) of the knuckle plate (3) and the second pair of connecting portions (2b) of the bracket (2) is connected by the second eccentric bolt (5b), to selectively displace the knuckle plate (3) relative to the bracket (2). In the illustrative embodiment, displacement [i.e., pivoting] of the bracket (2) relative to the base plate (1) may be considered as a first condition of the mechanism (100) for adjusting toe of the wheel (102), while displacement [i.e., pivoting] of the knuckle plate (3) relative to the bracket (2) may be considered as a second condition of the mechanism (100) for adjusting camber of the wheel (102).
[0036].In an embodiment, the fastening element (4) may be a bolt, a nut, a rivet, a clamp and any other element capable of detachably connecting the bracket (2), the base plate (1) and the knuckle plate (3). Further, the first eccentric bolt (5a) and the second eccentric bolt (5b) may be defined with a cam profile [not explicitly shown in figures], which may be configured to engage with at least a portion of the bracket (2) and the knuckle plate (3) such that operation

of the first eccentric bolt (5a) and the second eccentric bolt (5b) may selectively displace the bracket (2) and the knuckle plate (3) respectively. Nature of displace of the bracket (2) and the knuckle plate (3) due to the first eccentric bolt (5a) and the second eccentric bolt (5b) may depend at least on nature of contact and direction of rotation.
[0037].In an embodiment, to receive the fastening elements, the first eccentric bolt (5a) and the second eccentric bolt (5b), the bracket (2) may be defined with an aperture in each of the first pair of connecting portions (2a) and the second pair of connecting portions (2b), as seen in Figure 5. Meanwhile, each of the pair of first engaging portions (1a) of the base plate (1) and each of the pair of second engaging portions (3a) of the knuckle plate (3) are defined with a plurality of receiving portions (7). Such plurality of receiving portions (7) of the base plate (1) and the knuckle plate (3) assists in adjusting distance between the base plate (1), the bracket (2) and the knuckle plate (3). In an embodiment, range of adjustment of camber and toe may also depend on distance between the base plate (1), the bracket (2) and the knuckle plate (3). Due to such configuration of the mechanism (100), range of adjustment of toe and camber of the wheel (102) of the vehicle may be increase and requirements of additional components such as intermediate links may be avoided. Also, such configuration of the mechanism (100) may limit frictional contact between the bracket (2), the base plate (1) and the knuckle plate (3), whereby improving durability of the wheel (102) and the axle assembly (101) of the vehicle.
[0038].In the illustrative embodiment, the first eccentric bolt (5a) may be connected along a first direction of the bracket (2) such that, the cam profile of the first eccentric bolt (5a) may adaptably displace the bracket (2) relative to the base plate (1). Based on said displacement of the bracket (2), toe angle of the wheel (102) may be adjusted. On the other hand, the second eccentric bolt (5b) may be connected along a second direction of the bracket (2) such that, the cam profile of the second eccentric bolt (5b) may adaptably displace the knuckle plate (3) relative to the bracket (2). Based on said displacement of the knuckle plate (3), camber angle of the wheel (102) may be adjusted. In an embodiment, the first direction and the second direction may be along a longitudinal axis and a transverse axis of the bracket (2), respectively. i.e., the first eccentric bolt (5a) may be coupled the bracket (2) along a vertical direction and rotatable about a vertical axis, while the second eccentric bolt (5b) may be coupled the bracket (2) along a horizontal direction and rotatable about a horizontal axis. Here, orientation of the first eccentric bolt (5a) and the second eccentric bolt (5b) may not be

construed as a limitation, rather the same may be interchangeable in connection with the base plate (1), the bracket (2) and the knuckle plate (3).
[0039].Based on such configuration of the mechanism (100), toe and camber of the wheel (102) may be selectively adjusted based on operation of the first eccentric bolt (5a) and the second eccentric bolt (5b) relative to the bracket (2) and the knuckle plate (3). Such adjustment of toe and camber can be seen in Figures 6 and 7, respectively. For instance, in case where toe angle of the wheel (102) may be required to be adjusted, the first eccentric bolt (5a) may be operated in a first direction (e.g., clockwise direction) for pivotal movement of the bracket (2) relative to the base plate (1). Such pivotal movement of the bracket (2) may be configured to displace the knuckle and in-turn the projecting member (8) being connectable to the wheel (102), for adjusting toe of the wheel (102). When viewed from top of the axle assembly (101), adjustment of the toe may be determined based on deviation from the first reference axis (H-H) when compared to Figure 2. Similarly, in case where camber angle of the wheel (102) may be required to be adjusted, the second eccentric bolt (5b) may be operated in a first direction (e.g., clockwise direction) for pivotal movement of the knuckle plate (3) relative to the bracket (2). Such pivotal movement of the knuckle plate (3) may be configured to displace the projecting member (8) being connectable to the wheel (102), for adjusting camber of the wheel (102). When viewed from side of the axle assembly (101), adjustment of the camber may be determined based on deviation from the second reference axis (I-I) when compared to Figure 3.
[0040].In an embodiment, range of toe and camber may also be regulated based on factors including the cam profile of the first eccentric bolt (5a) and the second eccentric bolt (5b), nature of the aperture in the bracket (2), nature of the plurality of receiving portions (7) in the knuckle plate (3) and the base plate (1), and the like.
[0041].In an embodiment, for determining and calibrating toe and camber of the wheel (102), a head portion of the first eccentric bolt (5a) and the second eccentric bolt (5b) may be defined with a plurality of graduations (not seen in figures), Alternatively, at least one of the base plate (1), the bracket (2) and the knuckle plate (3) may be defined with a reference mark (not seen in figures) to denote instantaneous value. In an embodiment, the first eccentric bolt (5a) and the second eccentric bolt (5b) may be defined with a plurality of graduations while one of the base plate (1), the bracket (2) and the knuckle plate (3) may be defined with the reference mark for effortlessly adjusting camber and toe of the wheel (102).

[0042].In an embodiment, the mechanism (100) is simple in construction, compact in assembly and may be automated in an assembly line of a production unit.
[0043].In an embodiment, the mechanism (100) eliminates additional components, thereby rendering cost effective approach for adjusting camber and toe of the wheel (102) of the vehicle.
[0044].EQUIVALENTS
[0045].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.
[0046].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.”
[0047].In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
[0048].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.
