The utility model relates to the installation structure of the air permeable plug of the driving axle. In order to solve the problem that the air permeable plug of the existing driving axle is easily submerged by dust and sediment and can not exhaust normally, which results in the failure of the driving axle, the utility model constructs an installation structure of the air permeable plug of the driving axle, including the driving axle housing, the air permeable plug and the air permeable nozzle seat, which are on the driving axle housing It is equipped with exhaust threaded holes. The lower end of the exhaust nozzle seat is provided with external threads. The upper end of the internal holes of the exhaust nozzle seat is provided with internal threads. The exhaust plug is arranged on the upper end of the exhaust nozzle seat and connected with the internal holes of the upper end of the exhaust nozzle seat. The exhaust threaded holes of the exhaust nozzle seat are arranged on the driving axle housing. In the utility model, the air permeability plug is heightened so that it is not easy to be buried by dust and sediment and the air permeability plug channel is blocked. At the same time, the exhaust passage and the axle housing exhaust hole are heightened and thickened, and the oil in the driving axle housing is far away from the inlet of the heightened air permeability plug, which makes it difficult for the oil to enter the air permeability plug inlet and solves the fuel injection problem of the driving axle air permeability plug.

驱动桥透气塞安装结构
本技术涉及一种透气塞安装结构,更具体地说,涉及一种驱动桥透气塞安装结构。
技术介绍
驱动桥内具有诸多高速转动的齿轮和轴,这些部件高速转动工作时会产生大量的热量,导致驱动桥内温度升高,驱动桥内空气膨胀,压力升高,升高的压力有可能造成驱动桥部分界面和密封处漏油。为防止驱动桥部分界面和密封处漏油,在驱动桥的桥壳上安装有透气塞,当桥总成内外气压差大于透气塞调定的压力时,透气塞内部的压力开启阀就会被开启,桥总成内部高压气体经透气塞气道排出桥外。现有的工程机械驱动桥透气塞安装是在驱动桥的桥壳上设置一个排气螺纹孔,透气塞直接插装在该排气螺纹孔内,通过螺纹连接实现密封,透气塞凸出桥壳外表面仅有20毫米左右。由于工程机械工作环境比较恶劣,驱动桥在使用中壳体表面会积有大量的灰尘、泥沙,因此仅凸出驱动桥壳体表面的透气塞容易被灰尘、泥沙淹埋,封堵透气塞气道,造成桥壳内部高压气体无法顺利排出,驱动桥内部气压不断升高,部分密封面漏油,导致驱动桥故障。
技术实现思路
