[0001] The present subject matter described herein, relates to a mounting assembly of a steering angle sensor. More particularly, to a mounting assembly of a steering angle sensor on a steering arm of vehicle.
BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Generally, steering angle sensor is mounted over a steering column with the help of a contact coil, in case of in built airbag feature variants or a lighting switch, in case of in built auto light feature variants. The purpose of the contact coil is to help in opening of airbags when the crash happens and the purpose of the lighting switch is to maneuver head lights of the vehicle automatically.
[0004] Technical Problem: In vehicles of low variants, original equipment manufacturers (OEM's) do not provide airbags or automatically maneuvering head lights due to cost factors. As per the norms of the government, the usage of electronic stability control or electronic stability program has been made mandatory in the vehicles for road safety. The steering angle sensor is a component of electronic stability control. Now, the question arises on the location of mounting of the steering angle sensor in the absence of the contact coil or the lighting switch.

[0005] One solution for the above mentioned technical problem disclosed in prior patent application publication CN105835939A is to integrally mount the steering wheel angle sensor on the steering column. The steering column of the integrated steering wheel angle sensor includes a tube body arranged outside a steering wheel rotation shaft in a sleeving mode, wherein the tube body comprises an upper tube body and a lower tube body, a flange body is arranged at the upper end of the lower tube body, a housing body with an open lower end is arranged at the lower end of the lower tube body, and the lower end face of the housing body is fixedly connected with the flange body through a bolt to form a housing for configuring the steering wheel rotation angle sensor. A first opening portion is formed in one side face of the housing body, a second opening portion is formed in the other side, the opening angle of the first opening portion is not greater than 180 degrees, the first opening portion is used for configuring a detection body of the steering wheel rotation angle sensor, and the second opening portion is used for configuring a limiting rod of the steering wheel rotation angle sensor. Rapid integration of an ESP system can be achieved on the basis that a combination switch, a clock spring, a steering wheel assembly, a steering lock assembly and the like are not changed, the varieties of newly developed parts are decreased, a development period is shortened, and the development costs are reduced.
[0006] Another solution for the above mentioned technical problem disclosed in prior patent application publication CN207374482U is to provide a steering pipe column with an angle speed sensor of a steering wheel, which comprises a steering pipe column body, a multi-angle sensor of a steering wheel, an upper bracket and an output shaft connected with one end of the body, wherein, the multi-angle sensor is arranged on the body. The steering pipe column is characterized in that the sensor is connected with the upper bracket through a fixed bracket. The angle speed sensor of a steering wheel of the steering pipe column is fixedly arranged at the bottom of a steering pipe column assembly through the fixed bracket, therefore, the steering

angle of the steering wheel can be well recorded by the angle speed sensor, the errors because of assembly results are decreased, the selection of an electric stabilizing program ESP is convenient, the development of a new steering pipe column is not required, the commonality is kept, and the development cost is reduced.
[0007] Existing solutions or structures provide information on currently available solutions for mounting the steering angle sensor on the steering column, but each has its own drawbacks and limitations. For example, there may be situations where it is difficult to mount the steering angle sensor on the steering column due to limitation of space, design complexity, and so on. These known systems do not provide solution to mounting of the steering angle sensor on a steering arm.
[0008] Therefore, a simple and in-expensive solution is required for mounting the steering angle sensor at a new location.

[0031] As shown in figures 1(a), 1(b), 1(c) and 1(d), there is provided a
mounting assembly 400 of a steering angle sensor 300 comprising a steering arm 402, a slit plate 404, a bolt 406, a nut 408, a locking pin 410 and a dust cover 412.
[0032] The steering angle sensor 300 is provided with integrally formed flanges
25 300(a1) on its either side. The integrally formed flanges 300(a1) are provided with
holes 300(a12).
8

[0033] Referring to figure 1(a), the steering arm 402 is angularly bent with one
end connected to a tie rod 602 of a steering gear box 600 and the other end
connected to a plurality of axles 800. The steering arm 402 comprises a steering
housing 402(a) integrally formed and extending out from its centre as shown in the
5 figure 1(c). The steering housing 402(a) is provided with integrally formed bosses
402(a2) at opposite sides of its free end complementary to the integrally formed flanges 300(a1) of the steering angle sensor 300 as shown in the figure 1(d). The bosses 402(a2) of the steering housing 402(a) are provided with threaded holes 402(a21) complementary to the holes 300(a12) of the steering angle sensor 300.
10 [0034] Referring to figure 1(d), the slit plate 404 is provided with a plurality of
slits 404(a) around its circumference to accommodate a notch 304 extending from the interior of steering angle sensor 300.
[0035] The arrangement of the mounting assembly 400 of the steering angle
sensor 300 is as follows: Firstly, a dust cover 412 is inserted into the steering
15 housing 402(a) from its free end. Secondly, a bolt 406 is inserted into the dust
cover 412 and extends out through the steering housing 402(a). Thirdly, the steering angle sensor 300 is positioned over the steering housing 402(a) with the bolt 406 extending therein and locked in position to the bosses 402(a2) of the steering housing 402(a) by means of a plurality of bolts or screws passing through
20 the threaded holes 402(a21) of the steering housing 402(a) and the holes 300(a12)
of the steering angle sensor 300. Fourthly, the slit plate 404 is inserted into the bolt 406 to rest over the dust cover 412 in such a way that the plurality of slits 404(a) accommodates the notch 304 extending from steering angle sensor 300 and arrests its movement within the steering angle sensor 300. Fifthly, the nut 408 is engaged
25 to the bolt 406 by clockwise/anticlockwise rotation depending on the thread

5 [0037] 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
10 “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
15 “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
20 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
25 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,
10

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."
[0038] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
