Technical Field
The utility model belongs to the technical field of the automobile drive axle, concretely relates to transaxle breather plug connecting pipe.
Background
In order to prevent external silt, sewage, dust and other pollutants from entering the drive axle to cause early wear of the internal gear of the drive axle, and prevent the internal oil temperature of the drive axle from rising to increase the internal pressure of the drive axle to cause oil leakage at the parts such as a half-axle oil seal and a main reducing oil seal, a vent plug is usually arranged on the drive axle or the main reducing shell. Most of the existing vent plugs are steel welding structures, complex in structure and high in cost.
The conventional common vent plug takes a common bolt as a body, and a through hole is drilled in the core part of the bolt to realize the ventilation function; a groove is formed in the head to seal the head hole to prevent water from entering. However, the drilling of the steel bolt is complex in process, high in cost and heavy in weight, and when the gear runs at a high speed, gear oil can be thrown out through the vent plug, so that the oil spilling phenomenon occurs, and the existing vent plug and the connecting piece thereof are inconvenient to use.

The utility model discloses a following technical scheme realizes above-mentioned purpose:
the utility model provides a drive axle breather plug connecting pipe, includes the connecting rod of being connected with the axle housing, the lower part branch of connecting rod is formed with the knee to the side bend, the knee is located the inside of drive axle, the inside intercommunication of connecting rod and knee, the upper end of connecting rod is connected with the breather plug, the surface of connecting rod is provided with helicitic texture, the connecting rod is connected with the nut piece through helicitic texture.
As a further optimization scheme of the utility model, the fixed surface of connecting rod is connected with the sealing washer.
As a further optimization scheme of the utility model, the air vent has been seted up to the surface of knee, the air vent be located crooked side.
As a further preferred embodiment of the present invention, the vent hole of the vent plug is located at the lower end thereof.
As a further optimization scheme of the utility model, the breather plug with connecting rod threaded connection, the vertical air channel has been seted up to the internal surface wall of breather plug.
As a further optimization scheme of the utility model, the outer fixed surface of connecting rod is connected with the spacing ring, the spacing ring is located between breather plug and the nut piece.
The beneficial effects of the utility model reside in that: the utility model is provided with the elbow pipe, and the elbow pipe is positioned inside the drive axle, thus saving the external space, meanwhile, because the pipe orifice of the elbow pipe is bent, the oil liquid inside the drive axle can be effectively prevented from entering the pipe orifice and being thrown out, and the elbow pipe is installed from the inside of the drive axle, thereby saving the external space, avoiding the gear and reasonably utilizing the internal space of the axle housing; the whole device is simple in structure, convenient to operate, good in sealing effect, strong in ventilation effect and convenient to popularize and use.
