TECHNICAL FIELD
[001] The subject matter in general relates to a braking assembly of an
automobile. More particularly, but not exclusively, the subject matter relates to prevent entry of foreign particles into the brake assembly of an automobile.
BACKGROUND
[002] Background description includes information that may be useful in
understanding the present subj ect matter.
[003] Referring to FIG. 1, a conventional brake mounting assembly 10 is
disclosed. The brake mounting assembly 10 comprises an end plate 12 and a back plate 18 that are affixed to each other using fasteners. Spindle 14 is welded to end plate 12 and spacer 16 is press fitted to spindle 14. Further, an adhesive is provided in between the end plate 12 and the back plate 18 to act as a barrier to foreign particles, for example, dust and water trying to enter the brake assembly.
[004] However, the adhesive comes in contact with the spacer 16 thereby
bonding the spacer 16 to the back plate 18. This may prove to be a problem during the disassembly and assembly of the brake assembly as the spacer 16 may come along as the back plate 18 is being removed.
[005] Also, in the absence of adhesive, foreign particles are free to enter into
brake assembly, which is a cause for concern.
[006] FIG. 2 discloses the high stress region in the back plate 18 which is in
contact with the spacer 16. The stress distribution along the contact region is localized. During cornering, vehicle experiences loads in lateral direction. Loads from tire contact point are transferred to rear suspension. Since spacer is a load carrying member, during cornering the top surface of the spacer experiences tension while bottom one experiences compression. As a result, localized load transfer occurs between spacer and back plate.

[007] Therefore, there is a need of end plate design that can solve the above
mentioned technical problems.

DETAILED DESCRIPTION
[0033] The detailed description of various exemplary embodiments of the disclosure is described herein with reference to the accompanying drawings. It should be noted that the embodiments are described herein in such details as to clearly communicate the disclosure. However, the amount of details provided herein is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the scope of the present disclosure as defined by the appended claims.
[0034] It is also to be understood that various arrangements may be devised that, although not explicitly described or shown herein, embody the principles of the present disclosure. Moreover, all statements herein reciting principles, aspects, and embodiments of the present disclosure, as well as specific examples, are intended to encompass equivalents thereof.

[0036] It should also be noted that in some alternative implementations, the functions/acts noted may occur out of the order noted in the figures. For example, two figures shown in succession may, in fact, be executed concurrently or may sometimes be executed in the reverse order, depending upon the functionality/acts involved.
[0037] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. It will be further understood that terms, e.g., those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
[0038] Referring to FIGs. 3-8, disclosed is a brake mounting assembly 100 for preventing the flow of foreign particles into the brake assembly. The brake mounting assembly 100 comprises a back plate 102, an end plate 104, and a spacer 306. The end plate 104 is configured to be welded with trailing arm 106 of a rear axle (not shown). The back plate 102 defines a first through-hole 202 and the end plate 104 defines a second through-hole 302.
[0039] In an embodiment, the second through-hole 302 defined by the end plate 104 is configured to allow a spindle 404 to pass through. The spindle 404 also passes through the first through-hole 202 defined by the back plate 102.
[0040] The back plate 102 and the end plate 104 are attached to each other using fasteners at dedicated mounting holes provided on the end plate 104 and the

back plate 102. Further, an adhesive is provided in between the back plate 102 and the end plate 104 such that a front face 402 of the end plate 104 is in contact with the back plate 102.
[0041] The end plate 104 defines a plurality of fastening through-holes 308 to allow a plurality of fasteners to pass through. Similarly, the back plate 102 also defines a plurality of fastening through-holes 204 corresponding to the plurality of fastening through-holes 308 to allow a plurality of fasteners to pass through. The plurality of fasteners is used to fasten the end plate 104 to the back plate 102.
[0042] In an embodiment, the fasteners may be any one of nut and bolt, or screws, among others.
[0043] Referring to Fig. 5 and 6, the end plate 104 defines a protrusion 304 around the second through-hole 302. In an embodiment, the protrusion 304 may assume the shape of the second through-hole 302. As an example, the protrusion 304 may be circular or oval in shape. The protrusion 304 is protruded away from the outer face 402 of the end plate 104 toward the back plate 102 along direction of the spindle 404, as shown in Fig. 7.
[0044] In an embodiment, a spacer 306 is provided along the spindle 404 adjacent to the end plate 104 and away from the axle 106. The spacer 306 and the spindle 404 are press fitted to each other. One end of the spacer 306 may be configured to be in contact with the front face 402 of the end plate 104.
[0045] In an embodiment, the spacer 306 is held within the protrusion 304 defined by the end plate 104. The outer diameter of the spacer 306 is less than internal diameter of the protrusion 304.
[0046] The spacer 306 is configured to support a spindle bearing 502 and restrict the axial movement of the spindle bearing 502. The spacer 306 act as a load carrying member to the end plate 104.
[0047] In an embodiment, the back plate 102 is configured to rest on the

protrusion 304 such that the first through-hole 202 sits on the protrusion 304. The resting of the back plate 102 on the protrusion 304 avoids the back plate 102 from coming in contact with the spacer 306.
[0048] The protrusion 304 prevents the adhesive that is used to bond the end plate 104 to the back plate 102 from coming in contact with the spacer 306. This prevents the back plate 102 from bonding to the spacer 306, whereby the back plate 102 can be removed separately while dismantling the brake assembly without having the spacer 306 coming out along with the back plate 102.
[0049] As the back plate 102 rests on outer circumference of the protrusion 304 of the end plate 104, The protrusion 304 prevents the entry of foreign particles such as dust into the brake assembly 100 even in the absence of the adhesive.
[0050] In an embodiment, the adhesive along with the protrusion 304 provides a double resistance to the foreign particles from entering into the brake assembly.
[0051] Referring to fig. 5 and Fig. 6 together, radius Rl of the first through-hole 202 defined by the back plate 102 is larger than outer radius R2 of the protrusion 304.
[0052] In an embodiment, height of the protrusion 304 in direction of the spindle 404 is more than thickness of the back plate 102. In another embodiment, the height of the protrusion 304 from the outer face 402 is equal to thickness of the back plate 102.
[0053] FIG. 8 discloses the high stress region of the back plate 102 along the region where the back plate 102 is in contact with protrusion 304 on end plate. The stress distribution along the contact region (through-hole 202) is uniformly distributed in an embodiment as a result of increase in contact area with protrusion 304 and absence of direct contact with spacer 306 as opposed to the localized distribution in existing brake mounting assembly 10 (shown in FIG. 2). The uniform stress distribution in the back plate 102 prolongs the life of the back plate

102, thereby prolonging the life of the brake mounting assembly 100.
