[0002] As people pay more and more attention to environmental protection and energy conservation, new energy vehicles have gradually become a trend. However, compared with traditional vehicles, new energy vehicles still have transmissions, which leads to the need for transmission-related product requirements in the structure of the vehicle. Therefore, reducing the overall weight of the vehicle and reducing power loss has become a technical difficulty and research hotspot; the transmission is an important component of new energy vehicles. The automobile transmission is a set of transmission devices used to coordinate the engine speed and the actual driving speed of the wheels to give full play to the engine's optimal performance. The transmission can produce different gear ratios between the engine and the wheels during the driving process of the car; refer to the Chinese patent, application number: "202223239113.6" "A low-pressure casting transmission housing", which solves the existing small housing deformation using lost foam casting, resulting in more waste, low yield, and poor surface finish and density.
