Description

Technical Field

[0001] This application relates to the technical field of automotive transmission housings, and more particularly to an automotive transmission housing. Background Technology

[0002] In the current automotive industry, in order to provide external protection and lubrication for the car's transmission, the transmission is usually installed inside a transmission housing. Lubricating oil is then added to the transmission housing. This not only protects the transmission inside the housing but also allows the lubricating oil to lubricate the transmission, effectively extending the transmission's service life.

[0003] However, existing automotive transmission housings have the following drawbacks: when an oil pan is damaged and leaks oil, the existing transmission housing can quickly detect the leak by checking the internal transmission fluid level. However, when leaks occur due to insufficient sealing of the transmission housing cover gasket, the leakage is very slow. Therefore, by the time the driver detects the leak through the fluid level sensor, the actual leakage in the transmission housing has already been ongoing for a long time. In summary, current transmission housings do not provide a rapid warning for continuous, small-volume leaks. Summary of the Invention

The second mounting protrusion is fixedly connected to the inside of the first mounting protrusion by hexagonal bolts, and the inner wall of the inner protective shell is fixedly connected to a reinforcing rib.

[0007] A sensor interface is fixedly connected to the upper end face of the transmission housing. An oil detection sensor is installed inside the sensor interface, and the detection end of the oil detection sensor is attached to the oil-absorbing fiber layer.

[0030] A first sealing ring 16 is movably connected on one side of the inside of the transmission housing 1, and the outer wall of the first sealing ring 16 is attached to the outer wall of the inner protective shell 15. The first sealing ring 16 is arranged to ensure the installation sealing performance of the inner protective shell 15 at the first shaft hole 4 of the transmission housing 1.
