Abstract
The utility model discloses a breather for an automobile drive axle, which comprises screw caps and a breather plug, wherein the screw caps are matched and connected with the breather plug through a thread, a retainer ring is arranged between the screw caps and the breather plug, and a sealing ring is arranged on the connecting part of the screw caps and the breather plug. The breather comprises the screw caps, the retainer ring, the breather plug and O-shaped rings, wherein the screw caps are matched and fastened with the breather plug through the thread together, the retainer ring is positioned between the screw caps and the breather plug and is of a groove structure, thus less oil leakage and better breathing can be effectively prevented; and the O-shaped sealing rings are respectively between the screw cap and the breather plug and between the screw caps, thus better tightness is achieved. The breather can be directly inserted on an axle housing, is convenient for use, is suitable for multiple types of automobile types, and is good in actual use effect through actual installation and probation.
Description
Technical field
The utility model relates to low-floor bus bridge field, and specifically a kind of utility model automobile drive axle is used aerator.
Background technology
As automotive axle inside and exterior intercommunicating device; In order to prolong the service life of inner each movable parts of vehicle bridge and lubricating oil; Aerator should have better seal property, be convenient to processing, install and maintenance, but present intercommunicating device soybean all in use sealing property is relatively poor; And leakage of oil easily causes the vehicle bridge internal lubrication to go wrong.Structure aerator often commonality is relatively poor, and complicacy is installed, and maintenance is big.
Summary of the invention
To the deficiency that prior art exists, the utility model technical matters to be solved is, but a kind of automobile drive axle that provides a kind of actv. simple in structure, easy to use to prevent a small amount of oil impregnate and better ventilation is used aerator.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of automobile drive axle is used aerator; Comprise nut and breather stem vent plug; Said nut is connected through screw thread fit with breather stem vent plug, between said nut and breather stem vent plug, back-up ring is set, and the connecting portion of said nut and breather stem vent plug is provided with seal ring.
Above-mentioned automobile drive axle is used aerator, and said back-up ring inwall is provided with to the inner annular groove that extends of back-up ring.
The utility model automobile drive axle with the advantage of aerator is: this structure aerator is made up of nut, back-up ring, breather stem vent plug and O type circle; Nut and breather stem vent plug tighten together through screw thread fit; Back-up ring is positioned between the two, and the fluted structure of back-up ring, can prevent a small amount of oil impregnate and better ventilation by actv.; The O RunddichtringO is all arranged between nut and nut and the breather stem vent plug, and leak tightness is very good.This structure can directly be inserted and is used on the axle housing, and is easy to use, is applicable to multiple vehicle, and on probation through actual entrucking, practical effect is very good.
