The inside of the car gearbox is filled with hydraulic oil, which can play a role in lubrication and heat dissipation. There is a certain pressure inside the gearbox. Loss of pressure indicates that the gearbox has a fault, so its bottom shell needs to have the function of pressure resistance and good heat dissipation to improve the performance of the gearbox. In order to solve this problem, a bottom shell component with good pressure resistance and heat dissipation is provided. Utility Model Content

[0003] In view of this, the technical problem to be solved by the present invention is to provide a bottom shell component with good pressure resistance and heat dissipation, which solves the problem that the bottom shell components in the prior art have general pressure resistance and heat dissipation functions.

[0004] In order to solve the above technical problems, the utility model discloses a bottom shell component with good pressure resistance and heat dissipation, including: a bottom shell component body and a sealing gasket; the bottom shell component body is die-cast in one time, the inner wall of the bottom shell component body is a draft bevel, the bottom surface has a first plane, a second plane and three inclined surfaces, the draft bevel and the first plane are provided with multiple guide ribs, the second plane is provided with an oil outlet hole and an oil plug screw, and the three inclined surfaces converge toward the second plane; a fixed sealing part is provided at the edge of the bottom shell component body, and a fixing hole, a sealing groove and a baffle are provided on the fixed sealing part.

[0005] Furthermore, the above-mentioned guide ribs all protrude toward the interior of the bottom shell body.

[0006] Furthermore, the height of the first plane is higher than the height of the second plane.

[0007] Furthermore, the multiple guide ribs on the first plane are parallel to the direction of the second plane.

[0008] Furthermore, the plurality of guide ribs on the draft slope face the bottom surface of the bottom shell body.

[0009] Compared with the existing technology, this application can achieve the following technical effects:

[0010] The utility model arranges the interior of the bottom shell into a high-low drop structure, which is conducive to the transmission oil inside being carried up by the gears and then flowing back through the high-low structure to transfer heat to the bottom shell, and the heat is dissipated through the bottom shell to prevent the transmission from overheating; the second plane is at the lowest point, and the metal slag worn inside the transmission can be well settled to the bottom for easy discharge; the guide ribs on the bottom shell not only facilitate the return and diversion of the transmission oil, but also improve the rigidity of the bottom shell and enhance the external pressure resistance.

[0011] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
