Problems solved by technology

The pressure of the lubricating oil will further increase, causing the lubricating oil to overflow from the orifice of the transmission exhaust plug. Such a cycle may even match the exhaust hole, causing the exhaust plug to completely lose the function of exhaust.

Abstract

The invention discloses an air release plug of an antiseep automobile transmission, and the air release plug is used for solving the seepage problem of an existing air release plug. The air release plug comprises a plug cap and a plug body with an exhaust cavity, wherein the plug cap sleeves the plug body; an annular air outlet is formed between the inner wall of the plug cap and the outer wall of the plug body; the exhaust cavity is internally provided with a vent pipe; the vent pipe comprises an outer shell and an inner shell with a cavity; the outer shell sleeves the inner shell so as to form a vacuum steam cavity; two end parts of the outer shell are connected with the inner shell by virtue of end caps; a wick is paved on the outer wall of the steam cavity. and the steam cavity is filled with working liquid; the lower end of the cavity of the inner shell is communicated with that of a vent cavity; the upper end of the cavity of the inner shell is communicated with that of the vent cavity; the periphery of the outer shell is provided with a pipe shell in a sleeving way; a sealed cooling cavity is formed between the pipe shell and the outer shell and is filled with cooling liquid.

Description

technical field [0001] The invention relates to a transmission of an automobile engine, in particular to an exhaust plug of an anti-leakage automobile transmission. Background technique [0002] At present, the exhaust plug device of the automobile engine is installed on the transmission shift box, which is located at the highest position of the transmission. The internal cavity of the transmission assembly is kept consistent with the external pressure through the exhaust hole to avoid the pressure increase of the gear lubricating oil. When the car is running, the gears of the transmission will rub against each other to generate a lot of heat, which will raise the temperature of the transmission lubricating oil to 70-80°C. The lubricating oil attached to the surface of the gear is thrown out from the tangential direction due to the centrifugal force generated by the high-speed rotation of the gear. Since the inner cavity of the exhaust plug does not have any blocking medium,...
