The present subject matter described herein relates to a bracket connected to a cross member of a vehicle. In particular, the present subject matter relates to a bracket structure provided on a cross member connected to a vehicle body for reducing vibration transfer from an engine to the vehicle body.
BACKGROUND
[0002] In an automobile, a powertrain and a transmission unit are mounted on a vehicle body using an engine mount. In a vehicle where the engine is mounted under the vehicle body, the engine mount is used to connected the engine to a cross member placed under the vehicle body.
[0003] During engine running condition, vibrational forces are developed on the engine mount and the cross member because the engine mount is directly connected to the powertrain and the transmission unit of the engine. Subsequently the vibrations may be transferred from the engine mount to the vehicle body through the cross members.
[0004] Moreover, due to the excessive vibration, there are chances of cross member deformation.
[0005] In the existing design of rear engine mount area, the engine mount is welded on the cross member and no other bracket or reinforcement is provided to prevent/reduce deformation of the cross member. Therefore, the existing design for engine mount doesn't provide sufficient rigidity to dampen the vibrations. Overall the vibrational loading which comes through the engine mount deforms the cross member to a very high extent. This kind of design leads to overall high vibration levels at rear engine mount area.

[0006] Therefore, it is required to provide a solution to increase stiffness of the cross member, thereby improving overall vibration levels.
OBJECTS OF THE DISCLOSURE
[0007] It forms an object of the present disclosure to overcome the aforementioned and other drawbacks/limitations in the existing solutions available in the form of related prior arts.

[0010] It is yet another object of the present disclosure to provide a cost effective solution to strengthen the cross member.
[0011] It is yet another object of the present disclosure to increase the comfort level inside the cabin.

[0034] Hereinafter, a description of an embodiment with several components in communication with each other does not imply that all such components are required. On the contrary, a variety of optional components are described to illustrate the wide variety of possible embodiments of the present disclosure.
[0035] The present invention discloses about a bracket for reinforcing a cross member that is connected to a vehicle underbody. The bracket improves the overall vibration transfer from an engine to the vehicle body.
[0036] Referring to FIG. 1, illustrating a bracket (100) positioned on a cross member (101) connected to vehicle underbody. The bracket (100) is formed of a first side surface (102a), a second side surface (102b), and a top surface (103). The top surface (103), the first side surface (102a), and the second side surface (102b) form a U-shaped structure. The first side surface (102a) and the second side surface (102b) have horizontal beads (104a, 104b). The bracket (100) houses a plurality of horizontal plates (105) that are supported by the horizontal beads (104a, 104b) from the ends. The bracket (100) adds stiffness to the cross member (101) when added in the high deformation area of the cross member (101) by improving rigidity of the overall structure against vibration transfer from engine mounted under the vehicle body.
[0037] The first side surface (102a) and the second side surface (102b) are parallel to each other and the bracket (100) is extended in the vehicle horizontal direction. One end (202a, 202b) of each of the first and second side surfaces (102a, 102b) is connected to the top surface (103) forming the U-shaped structure. Another end (203a, 203b) of the first side surface (102a) and the second side surface (102b) is connected to the cross member (101) located on the vehicle body (clearly explained in FIG.2). In an aspect, the bracket (100) is welded to lower surface of the cross member (101) as seen from under the vehicle body.

[0038] The top surface (103) has a planar surface forming a rectangle shape. The top surface (103) has through holes (106). The through holes (106) are positioned approximately at the lateral ends of the top surface (103). The through holes (106) are provided to insert a fastener through it.
[0039] The ends (203a, 203b) of the first side surface (102a) and the second side surface (102b) have a curved surface (201) (as provided in FIG. 2 and FIG. 3) that is connected to the cross member (101). In an aspect, the bracket (100) is welded to a high deformation area of the cross member (101) so as to reduce the deformation of the cross member (101) due to vibration loading.
[0040] The first side surface (102a) and the second side surface (102b) have the plurality of the horizontal beads (104a, 104b) and the horizontal beads (104a, 104b) are positioned in the vehicle longitudinal direction. The horizontal beads (104a, 104b) are provided on top of each other after a defined space between the two adjacent horizontal beads on the first side surface (102a) and the second side surface (102b) of the bracket (100). The first side surface (102a) and the second side surface (102b) have equal number of the horizontal beads (104a, 104b).
[0041] The horizontal beads (104a, 104b) form a hollow space that faces the inside of the U shaped structure of the bracket (100). The hollow space also acts as slots for adding the horizontal plates (105). The horizontal beads (104a, 104b) help in resisting the deformation of the bracket (100) against the vibrational loading.
[0042] One end of the horizontal plates (105) is connected to the first side surface (102a) and the another end of the horizontal plates (105) is connected to the second side surface (102b). The horizontal plates (105) are stacked inside the bracket (100). The horizontal plates (105) are supported on ends by the horizontal beads (104a, 104b).
[0043] The bracket (100) by its design is very rigid which reduces the deformation of the cross member (101). The bracket (100) has a provision to

incorporate horizontal plates (105) of variable thickness and different numbers in various combination making the overall design modular in nature.
[0044] Referring to FIG. 2 and FIG. 3, illustrating different isometric views of the bracket (100). As mentioned above, the bracket (100) is formed of the top surface (103) and the first side surface (102a) and the second side surface (102b) forming the U-shaped structure. The U-shaped structure creates the cavity inside to house multiple horizontal plates (105) of variable thickness.
[0045] The bracket (100) is extended in the vehicle horizontal direction. The top surface (103) has the plane surface and the ends (202a, 202b) of the top surface (103) are connected to the first side surface (102a) and the second side surface (102b). The top surface (103) have the through holes (106) to provide space for the fastener to insert through them to connect the top surface (103) to the horizontal plates (105).
[0046] The ends (203a, 203b) of the first side surface (102a) and the second side surface (102b) have a curved surface (201). The curved surface (201) matches the outer periphery of the cross member (101) to get properly attached on the cross member (101). The curved surface (201) of the first and the second side surfaces (102a, 102b) are further arc welded on the outer periphery of the cross member (101).
[0047] The first and the second side surfaces (102a, 102b) have multiple horizontal beads (104a, 104b) positioned in the vehicle longitudinal direction. The horizontal beads (104a, 104b) also act as the slot for adding multiple number of horizontal plates (105). The horizontal plates (105) are supported on the horizontal beads (104a, 104b) and the plates are further arc welded on the horizontal beads (104a, 104b).
[0048] The horizontal beads (104a, 104b) increase strength of the bracket (100) and also provides the slot for adding more horizontal plates (105) in the bracket (100). The slots in the horizontal beads (104a, 104b) to add more horizontal plates helps in adding mass, makes it effective against a wide range of vibration

frequencies. The number of the horizontal plates (105) added in the bracket (100) is based on the amount of damping required. For an instance, if the vibration levels in a certain vehicle model is different, the number of the horizontal plates (105) to be added in the bracket (100) can be varied.
[0049] The top surface (103) and the horizontal plates (105) have the through holes (106, 204, 205, 206) on the surface. The through holes (106, 204, 205, 206) on the horizontal plates (105) and the top surface (103) are located on the same position so that any fastener such as a bolt can be inserted easily.
[0050] Further, the bolt is fastened to a nut to connect the horizontal plates (105) with the top surface (103). The fastener provides additional strength to the bracket (100) and the plates (105) such that they remain rigid throughout the vibrational loading.
[0051] In another embodiment, the horizontal plates (105) are connected to each other. The bottom surface of each of the horizontal plates (105) is connected to the top surface of the other horizontal plate leaving no gap between them.
[0052] The horizontal beads (104a, 104b) act as the slot to add more plates in the bracket (100) by arc welding. The provision in the design to add more plates aids in adding mass to the bracket (100) which makes the bracket (100) effective against a wide range of vibration frequencies. The number of horizontal plates (105) are added based on the amount of damping required.
TECHNICAL ADVANTAGES
[0053] With the help of the solution as proposed herein in the context of the present disclosure, the vibration transfer from engine to the vehicle body is reduced.
[0054] The design of the present disclosure is able to reduce the deformation of the cross member that occurs due to the vibration from engine mounted under the vehicle body.

[0055] With the help of the present disclosure, the overall amplitude of vibration level inside the passenger cabin is reduced.
[0056] The bracket is easy to assemble in the cross member as only arc weld is required to connect with the cross member.
[0057] The number and thickness of the horizontal plates can be varied based on amount of vibration damping and the frequency range requirement.
[0058] 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 disclosures 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. Also, 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 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 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."
