Title:
OIL PUMP GAS-EXHAUST MECHANISM FOR AUTOMATIC TRANSMISSION, AND AUTOMATIC TRANSMISSION AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/253297
Kind Code:
A1
Abstract:
An oil pump gas-exhaust mechanism for an automatic transmission, and an automatic transmission and a vehicle, which belong to the technical field of automobile transmission. The oil pump gas-exhaust mechanism for an automatic transmission comprises a sensor plug-in assembly (3) and an oil pump for supplying oil to an automatic transmission, wherein the oil pump is fixedly connected to a transmission housing, the sensor plug-in assembly (3) is arranged on the housing of the oil pump, the sensor plug-in assembly (3) is located between the oil pump and the transmission, a gas exhaust hole (2) is provided on the sensor plug-in assembly (3), and the gas exhaust hole (2) is inclined upwards from an outlet end relative to a horizontal plane. When a vehicle is driven in a working condition involving wading or there is water splashing on the ground, the oil pump for the automatic transmission avoids an active "water retention" phenomenon due to the gravity of water droplets; and a waterproof base membrane (4) arranged inside the sensor plug-in assembly (3) ensures that heat generated by the working of the oil pump can be discharged, and a situation in which water is forced to flow back into the oil pump when serious wading is required can also be avoided, thereby achieving a double protection effect.
