Description

Ventilation joint for automobile automatic transmission vent pipe

Technical Field

The utility model relates to a car automatic gearbox equipment field, more specifically say, relate to a car automatic gearbox breather pipe is with joint of ventilating.

Background

The vent pipe assembly of the automatic transmission of the automobile is used for communicating the inside of the transmission with the atmosphere, so that the pressure inside and outside the transmission is kept consistent, and lubricating oil in the automatic transmission can smoothly flow. The breather pipe main part of the existing automobile automatic transmission is generally a rubber hose or a nylon pipe, one end of the breather pipe main part is fixed on the cut-off of the transmission, and the other end of the breather pipe main part is provided with a connector or a dustproof cap so as to block foreign matters from entering a pipeline and prevent the failure of the ventilation effect. The function of the ventilation joint is very critical, the ventilation joint can ensure the smooth ventilation between the automobile automatic transmission ventilation pipe assembly and the outside, can also ensure the stability of the air pressure in the transmission, and can also prevent foreign matters and liquid from entering a pipeline and preventing the water from entering the transmission.

The existing ventilation joint has the problems of insufficient ventilation or overlarge opening, so that the risk that foreign matters enter the pipeline exists, the reliability of product application is insufficient, the probability of failure is high, and the market position and the utilization rate of the product at a client are reduced.

Automobile automatic transmission breather pipe is with ventilating joint for the unusual design joint of passenger car pipeline, generally restricts the entering of external impurity and water according to customer's air flow demand and special structure, if when using under improper or the abominable condition of operating mode, probably lead to intaking in the pipeline and getting into impurity, water and impurity can flow into pipeline or derailleur in, follow-up can produce very big influence to the use of derailleur. If the ventilation is insufficient, the pressure relief capability of the transmission is weakened, and the internal temperature and pressure of the transmission are released, so that the use of the transmission is influenced.

For example, chinese patent No. CN201820730371.9 provides a ventilation cap for a transmission case, which includes a protection cover and a plug body, wherein an opening is formed at one end of the protection cover, the plug body is located in the protection cover, a first gas passage is formed in the plug body, an internal thread is further formed in the plug body and is in butt joint with a preset external thread of a ventilation pipe, and the first gas passage is communicated with the passage of the ventilation pipe. The plug body still is equipped with the boss, the boss with there is the space between the protection casing medial surface, gas passage two has still been seted up to the boss, gas passage two with gas passage one communicates. The ventilation cap of the gearbox is provided with a threaded structure on the plug body, and is mounted with the ventilation pipe in a threaded connection manner during use, so that the ventilation cap is convenient to dismount; only need dismantle during the maintenance the utility model discloses a gearbox vent cap can investigate whether the breather pipe blocks up, and convenient to use practices thrift cost of maintenance simultaneously. As can be seen from the attached drawings, fig. 1 and fig. 2, the first gas channel and the second gas channel are designed to be perpendicular to each other, and air is easily blocked at a vertical position when passing through the first perpendicular gas channel and the second perpendicular gas channel, so that turbulent flow is generated, the ventilation effect of the gas channels is reduced, the foreign matter prevention capacity of the ventilation cap is also reduced, and the protection capacity of the whole system is reduced.
