In order to reduce the impact of uneven roads on the transmission and ensure the normal operation of the transmission, a suspension assembly is usually used to install the transmission. The suspension assembly is installed between the powertrain and the body or subframe, and mainly includes a suspension and a bracket connected to the suspension. The suspension and bracket used to connect the transmission and the engine can support the weight of the transmission and determine the position of the transmission; isolate the vibration transmitted from the engine to the body; bear the torque and dynamic load output by the transmission; and act as a shock absorber to alleviate the body vibration caused by uneven roads.

[0003] The existing transmission suspension bracket is connected to the transmission suspension through fasteners. The transmission suspension bracket includes a bracket body and a support arm. The bracket body is connected to the transmission suspension. The first end of the support arm is fixed to the bracket body, and the second end of the support arm extends along the length direction of the vehicle body. Mounting holes are respectively opened on the bracket body and the support arm, and the mounting holes are connected to the fixing holes of the transmission through bolts, thereby realizing the fixation and connection of the suspension bracket and the transmission.

[0004] The above solution not only requires mounting holes and fixing holes to be opened on the suspension bracket and the transmission respectively, which reduces the strength of the transmission and the suspension bracket, but also the bolt connection method is prone to loosening after long-term use, which in turn causes NVH performance to fail to meet requirements and even transmission installation failure.

[0025] Please also read Figure 1 to Figure 2 The novel transmission housing and transmission assembly provided by the utility model are now described. The novel transmission housing and transmission assembly include a housing 1 and a suspension housing 2 arranged outside the housing 1. The housing 1 and the suspension housing 2 are an integral component, and the suspension housing 2 is provided with a mounting through hole 2011 along a first path, and the mounting through hole 2011 is used to accommodate a connection component connected to a vehicle body.

[0026] Compared with the prior art, the new transmission housing provided by the utility model integrates the suspension housing 2 with the housing 1, and is connected to the vehicle body parts through the mounting through hole 2011 opened on the suspension housing 2, which not only eliminates the mounting bracket and simplifies the installation steps, but also eliminates the need to open connection holes on the housing 1 and the suspension housing 2, thereby ensuring the strength of the housing 1 and the suspension housing 2. In addition, due to the integrated design, it is not necessary to use a connection part 202 such as a screw connection or a clamping part to fix the mounting bracket to the housing 1, which not only avoids the problem of connection failure caused by loosening of the connection part 202 during use, but also avoids the problem of increased noise caused by loosening of the connection part 202, thereby affecting the NVH performance of the whole vehicle.

[0027] Specifically, the gear transmission components of the transmission are arranged in the housing 1 .

[0028] Optionally, the suspension housing 2 and the box body 1 may be integrally formed by casting.

[0029] Optionally, a buffer ring is inserted into the mounting through hole 2011 to reduce the vibration force after the suspension housing 2 is mounted on the vehicle body component. The buffer ring can be a flexible component such as rubber. The buffer ring can be fixed to the suspension housing 2 by fluidization or other methods.

[0030] It should be noted that the connecting component may be a rubber bushing, and the component may also be composed of a rubber main spring, a flow channel plate, a decoupling plate, and a leather cup.

[0031] It should be noted that the first path is perpendicular to the axis of the transmission output shaft.

[0032] In some embodiments, see Figure 1 to Figure 2 The suspension housing 2 includes a mounting portion 201 and a connecting portion 202 connected to the mounting portion 201 along a second path, the second path is perpendicular to the first path, the connecting portion 202 connects the mounting portion 201 to the box body 1, and a mounting through hole 2011 is opened in the mounting portion 201.

[0033] On the one hand, the connection part 202 can increase the contact area between the mounting part 201 and the vehicle body part, thereby improving the firmness and stability of the connection. On the other hand, the connection part 202 can also provide support for the mounting part 201, thereby preventing the mounting part 201 from being displaced or deformed due to force after being connected to the vehicle body part, thereby increasing the overall strength of the suspension housing 2.

[0034] It should be noted that the second path is parallel to the axis of the transmission output shaft.

[0035] In some embodiments, see Figure 1 to Figure 2The connecting portion 202 includes a connecting area 2021 and supporting areas 2022 arranged on both sides of the connecting area 2021 along the second path. The connecting area 2021 is arranged outside the mounting portion 201, and the box body 1 and the mounting portion 201 are both connected to the supporting area 2022.

[0036] The connection area 2021 and the support area 2022 are connected to form an integral structure, so that the overall stability and strength of the connection part 202 are guaranteed. The support area 2022 is respectively connected to the mounting part 201 and the box body 1, which increases the connection firmness between the mounting part 201 and the box body 1, and can provide support force for the mounting part 201 to prevent the mounting part 201 from being displaced in the second path. The solution in this embodiment not only has the connection part 202 distributed on the entire outer peripheral surface of the mounting part 201, thereby improving the connection firmness between the connection part 202 and the mounting part 201, but also the connection area 2021 can also increase the strength of the mounting part 201, compensating for the strength problem of the mounting part 201 caused by the installation through hole 2011.

[0037] In some embodiments, see Figure 1 to Figure 2 The connecting portion 202 is a triangular structure, the bottom edge of the triangular structure is connected to the box body 1 , and the middle portion of the connecting portion 202 specifically accommodates the receiving hole of the mounting portion 201 .

[0038] The triangle is stable, and the connecting part 202 is set to a triangular structure. On the one hand, it has high stability and is not easy to deform. On the other hand, a receiving hole can be opened inside to achieve connection with the mounting part 201. Moreover, compared with polygonal or other shaped structures, it reduces its own volume and weight while ensuring connection with the box body 1, which is conducive to lightweighting of the entire vehicle.

[0039] Optionally, in the direction of the first path, the width of the connecting portion 202 is consistent with the width of the mounting portion 201 , or the width of the connecting portion 202 is 1-10 mm smaller than that of the mounting portion 201 .

[0040] In some embodiments, see Figure 1 to Figure 2 The connecting part 202 is a plate-like structure, and a plurality of connecting parts 202 are sequentially arranged along the first path, and a weight reduction space 204 is formed between two adjacent connecting parts 202 .

[0041] Compared with the solution in which the connecting portion 202 completely covers the mounting portion 201 in the first path, the solution in this embodiment can reduce the volume and weight of the connecting portion 202, which is conducive to achieving lightweight of the entire vehicle. In addition, the multiple connecting portions 202 are spaced along the first path, which can not only save materials and reduce costs, but also increase the number of connection points between the mounting portion 201 and the multiple connecting portions 202, and the strength of the mounting portion 201 is uniform.

[0042] In some embodiments, see Figure 1 to Figure 2The suspension housing 2 further includes a reinforcing rib 203 connecting the plurality of connecting portions 202 , and the reinforcing rib 203 is cross-arranged with the connecting portions 202 .

[0043] The reinforcing ribs 203 connect the multiple connecting parts 202 to form an integral structure. Compared with the design in which the multiple connecting parts 202 are independent of each other, the solution in this embodiment not only increases the stability and strength of the connecting part 202, but also can strengthen the strength of the mounting part 201, thereby reducing the probability of damage or deformation of the mounting part 201 after being subjected to force.

[0044] In some embodiments, see Figure 1 to Figure 2 The reinforcing ribs 203 are arranged on the outer wall of the mounting portion 201 , and a plurality of reinforcing ribs 203 are sequentially spaced apart along the circumference of the mounting portion 201 .

[0045] The reinforcing ribs 203 are arranged on the outer wall of the mounting portion 201 to increase the strength of the mounting portion 201. The plurality of reinforcing ribs 203 are distributed at intervals along the circumference of the mounting portion 201 to make the strength of the mounting portion 201 uniform and avoid damage caused by local stress concentration after being subjected to force.

[0046] In some embodiments, see Figure 1 to Figure 2 The novel transmission housing further includes a limit plate 3 disposed in the weight-reducing space 204 , and two ends of the limit plate 3 are respectively abutted against two adjacent connecting portions 202 .

[0047] The limiting plate 3 is arranged in the weight reduction space 204 and is respectively connected to two adjacent connecting parts 202, which can limit the two adjacent connecting parts 202 in the first path, increase the stability between the two adjacent connecting parts 202, and avoid deformation of the connecting parts 202 along the first path.

[0048] Optionally, the limiting piece 3 is connected to the outer wall of the box body 1 to increase the strength of the box body 1 .

[0049] In some embodiments, see Figure 1 to Figure 2 The novel transmission housing further comprises a reinforcing sheet 4 connecting the suspension housing 2 and the housing 1 , and the reinforcing sheet 4 is arranged on one side of the suspension housing 2 along the first path.

[0050] Based on the same inventive concept, the utility model also provides a transmission assembly, which includes any one of the novel transmission housings described above.

[0051] The transmission assembly provided by the utility model adopts the above-mentioned new transmission housing, and the suspension housing 2 is integrated with the housing 1, and connected to the vehicle body parts through the mounting through hole 2011 opened on the suspension housing 2, which not only eliminates the mounting bracket and simplifies the installation steps, but also does not need to open connection holes on the housing 1 and the suspension housing 2, thereby ensuring the strength of the housing 1 and the suspension housing 2. In addition, due to the integrated design, it is not necessary to use a connection part 202 such as a screw connection or a clamping part to fix the mounting bracket to the housing 1, which not only avoids the problem of connection failure caused by loosening of the connection part 202 during use, but also avoids the problem of increased noise caused by loosening of the connection part 202, thereby affecting the NVH performance of the whole vehicle.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
