The present subject matter described herein, relates to a mounting bracket to connect cylinder block of power train with chassis of a vehicle where the powertrain is inclined at angle with the chassis of the vehicle. The present subject matter, in particular, relates to an engine mounting bracket with a rubber mount with increased rigidity and improved noise, vibration, and harness (NVH) performance.
BACKGROUND OF THE INVENTION:
[002] Background description includes information that may be useful in understanding the present invention.
[003] Engine is the heart of the vehicle. A powertrain is mounted on vehicle by three point mounting by connection of engine cylinder block with vehicle body on right hand (RH) side and left hand (LH) side from rear end transmission case is mounted with Rear (RR) mount. This arrangement is common for installation of powertrain for three point system in a passenger or commercial car. Engine and power train mounted on vehicle body through RH and LH side supports. Supports fix engine and restrict motion of the Power train while vehicle movement. The way of placement of the chassis of the vehicle and the cylinder block of the powertrain furnish a long overhang structure between the chassis of the vehicle and the cylinder block of the powertrain. An exhaust manifold is placed adjacent the cylinder block. The parts of the powertrain are inclined at different angles with the chassis of the vehicle. Further, the cylinder block of the powertrain has different mounting planes which are offset from each other to receive the mounting bracket.
[004] Technical problem: To connect the cylinder block with the chassis via a rubber mount covering the long overhang structure above the exhaust manifold placed adjacent the cylinder block, a sheet metal bracket or casted bracket is

provided to mount to the different mounting planes of the cylinder block which are offset from each other. This bracket can cause the cylinder block to break away from the mounting points due to spring back effect of the sheet metal. This bracket can also cause the noise due to large contact surface between the sheet metal and the rubber mount.
[005] Some of the existing solutions to prevent the breakaway of the cylinder block from the mounting points are given below.
[006] Existing solutions use an additional bracket for fixing offset in the different planes of the cylinder block. The additional bracket is provided for fixing the mounting bracket at the lower mounting plane of the cylinder block. In another solution bracket is provided with a plurality of sleeves for fixing the mounting bracket at the lower mounting plane of the cylinder block. In one other solution two different brackets are provided to cover the long overhang structure between the powertrain and the chassis above the exhaust manifold placed near the cylinder block. The above solutions increase the number of child parts thus increasing the manufacturing and maintenance cost. Further, with the increased number of child parts there are chance of failure in the structure because of any part failure.
[007] Therefore, there is a need of a mounting bracket to connect the cylinder block with the chassis via a rubber mount covering the long overhang structure above the exhaust manifold placed adjacent the cylinder block and to mount on the different mounting planes of the cylinder block.

[0048] Non-limiting Definitions
[0049] In the disclosure hereinafter, one or more terms are used to describe various aspects of the present disclosure. For a better understanding of the present disclosure, a few definitions are provided herein for better understanding of the present disclosure.
[0050] Oblong: A shape that deviates from a rectangle due to elongation having parallel longitudinal edges and other edges are semicircular. In an embodiment, the oblong can be referred or considered stadium shape.
[0051] Parabolic: A curved shape where any point is on the circumference of the curve is at an equal distance from a fixed point (the focus), and a fixed straight line (the directrix). In an embodiment, a partial parabolic shape or semi parabolic shape can be referred as C shape.
[0052] Referring to Figure 1, illustrating an isometric view of mounting bracket 300 having a base plate 100 and an upper plate 200 joined with the base plate (100) by way of arc welding or any other known welding technique. The base plate 100 of the mounting bracket 300 is mounted with the cylinder block 500 of the powertrain by means of a plurality of fasteners 401, 402 and the upper plate 200 joined with the base plate 100.
[0053] Referring to Figure 2, illustrating the base plate 100 comprise a lower inclined mounting portion 101 with a first mounting portion 103 having a pair of mounting holes 108 to mount with an upper plane 501 of the cylinder block 500 (as shown in fig. 6) and a second mounting portion 104 having a pair of mounting holes 109 to mount with a lower plane 502 of the cylinder block 500 (as shown in fig. 6). As shown in fig. 6, the upper plane 501 and lower plane 502 are offset 112 from each other. In complementary with the profile of the cylinder block, the first mounting portion 103 and the second mounting portion 104 are offset with each other. The lower inclined mounting portion 101 is defined as curved structure for

stress distribution. The lower inclined mounting portion 101 eliminates requirement of additional brackets or sleeves provided earlier to achieve the mounting surface on same plane.
[0054] Further, a flange portion 107 extends at an angle from front end 105 of the lower inclined mounting portion 101 in upward direction, where the flange portion 107 provides strength to the lower inclined mounting portion 101. The lower inclined mounting portion 101 defines an oblong shaped cutout 110 in between the first mounting portion 103 and the second mounting portion 104 to provide strength and to distribute the stress experienced by the lower inclined mounting portion 101.
[0055] The base plate 100 further comprises an upper partial parabolic curved profile portion 102 which extends from rear end 106 of the lower inclined mounting portion 101. The upper partial parabolic curved profile portion 102 has an oblong shaped cutout 114 on curved profile, where a flange portion 111 extends toward the upper plate 200 from circumference of the oblong shaped cutout 114. This flange portion 111 reduces the spring back effect at the upper partial parabolic curved profile portion 102 and distributes the stress experienced by the upper partial parabolic curved profile portion 102 portion 102. Further, another oblong shaped cutout 113 may be provided in between rear end of the upper partial parabolic curved profile portion 102 and the oblong shaped cutout 114. It can be understood that the oblong shaped cutouts distribute the stress experienced by the base plates at different locations. Further, the upper partial parabolic curved profile portion 102 helps in reducing the spring back effect to increase rigidness and stability of the mounting bracket 300.
[0056] Referring to Figure 3 illustrating the upper plate 200 comprises a base portion 201 and a wall portion 202 which is extending from both longitudinal edges of the base portion 201 towards the base plate 100. Further, shape of the wall portion of the upper plate 200 is complementary with the profile of the base plate 100 so that base plate 100 and the upper plate 200 can join efficiently by means of Arc welding. A D-shaped cut out 204 is provided at front end 203 of the

upper plate 200 to allow access to the plurality of fasteners 108 mounted on the base plate 100. At rear end 206 of the base portion 201 of the upper plate 200, a stepped profile 207 is provided which defines a stepped cross-section profile 209. The stepped shaped profile 207 defines a pair of mounting holes to receive the rubber mount. In an embodiment, the pair of mounting holes can be arranged in longitudinal direction or in transverse direction on the stepped shaped profile 207. An another oblong shaped cutout 205 may be provided in between the D-shaped cut out 204 and the stepped profile 207. It can be understood that the oblong shaped cutout 205 distributes the stress experienced by the base portion 201.
[0057] Further, the base portion 201 and the wall portion 202 combinedly define a concave shape profile 208. The concave shape profile 208 is provided adjacent to the mounting holes 109 provided on the second mounting portion 104 of the based plate 100 to reduce the spring back effect at the rear end of the lower inclined mounting portion 101 of the base plate 100. The concave shape profile 208 provide rigidity and strength to the complete mounting bracket 300.
[0058] Referring to Figure 4 illustrating a top view of the mounting bracket 300 showing the joining of the upper plate 200 on the base plate 100. The lower edge of the wall portion 202 of the upper plate 200 is welded with the inner surface of the base plate 100 by way of arc welding or any other known welding technique. The wall portion 202 is welded with the base plate 100 at the upper partial parabolic curved profile portion 102 and also at the lower inclined mounting portion 101 of the base plate 100. The lower edge of the concave shape profile defined 208 in the wall portion 202 adjacent to the mounting holes 109 provided on the second mounting portion 104 may not have welding provision to avoid weld spatter around bolt area on the base plate 100. Also concave shape is provided to reduce the spring back effect at this portion.
[0059] Referring to Fig. 5 illustrating a perspective view of assembly of the mounting bracket 300 and rubber mount 400 where the rubber mount 400 is mounted or provided on the stepped cross-section profile 209 in the upper plate 200. It can be understood that the rubber mount 400 is provided between the

bracket 300 and the chassis to absorb the vibration during vehicle movement. The stepped cross-section profile 209 reduces the contact surface of the mounting bracket 300 with the rubber mount 400 to ensure minimum contact with the rubber mount 400 to avoid rubber noise inside cabin resulting in improved noise, vibration, and harness (NVH) performance.
[0060] Referring to Fig. 6 illustrating an exploded view of the mounting assembly showing a cylinder block 500 and the mounting bracket 300 to be mounted on the different planes of the cylinder block 500 by means of a plurality of fasteners 401, 402. The cylinder block 500 comprises an upper plane 501 and a lower plane 502 which are offset from each other. The first mounting portion 103 of the lower inclined mounting portion 101 is mounted on the upper plane 501 of the cylinder block 500 by means a pair of fasteners 401, and the second mounting portion 104 of the lower inclined mounting portion 101 is mounted on the lower plane 502 of the cylinder block 500 to ensure the accomplishment of the mounting of the bracket 300 to the cylinder block 500. The present subject matter discloses that the curved lower inclined mounting portion 101 is complementary to the upper plane 501 and the lower plane 502 of the cylinder block to demotivate the failure of the fastening of the bracket 300 to the cylinder block 500.
[0061] As discussed above, the disclosed bracket 300 is a sheet metal bracket which has a spring back effect on the primary function of mounting, but the shape and structure of the mounting bracket 300 reduces the spring back effect experienced by the mounting portions of the mounting bracket 300. The disclosed bracket 300 increases the overall strength and rigidity of the system and reduces the number of child components.
[0062] Advantages of the Invention:
1. The present invention reduces the number of child components of the mounting bracket.

2. The present invention provides a mounting bracket having a novel shape, complimentary to the cylinder block and exhaust manifold placed adjacent the cylinder block.
3. The present invention reduces the spring back effect of the sheet metal bracket.
4. The present invention reduces the rubber noise.
5. The present invention reduces the manufacturing and maintenance cost.
6. The present invention reduces the chances of failure of the mounting bracket.
