Abstract
The utility model discloses an anti-oil-escaping breather plug, which consists of a breather plug rod which is provided with a chamber and a breather plug top cover which is adaptive to the breather plug rod. A plurality of oil stopping steps with different sizes are arranged on the inner wall of the breather plug rod along the axis of the breather plug rod. Since the anti-oil-escaping breather plug consists of the breather plug rod and the breather plug top cover, the structure of the chamber of the breather plug rod is improved and the oil stopping steps at different levels are additionally arranged, oil is thrown in the chamber during working, the oil stopping steps stop the oil, the oil is effectively prevented from escaping, the escaping probability of lubricating oil in an axle housing is reduced and the phenomenon of gear and bearing ablation due to insufficient lubrication is reduced; and the pressure is balanced, the oil is saved, and the attractiveness of an axle and the entire vehicle is guaranteed.
Description
Technical field
The utility model relates to automotive field, specifically the breather plug of the used equilibrium air pressure of vehicle bridge on a kind of automobile.
Background technique
Ransaxle is one of important big assembly on the automobile, the effect of breather plug is that ransaxle is in the driving car load advances process, component such as the gear of vehicle bridge inside, bearing are rotation at a high speed, produce the environment of High Temperature High Pressure, cause vehicle bridge inside cavity air pressure to raise, breather plug just links to each other the air pressure of inside with outside atmosphere, make bridge bag air pressure inside and external pressure balance.At present, the breather plug inner chamber that adopts is vertical mode, when driven wheel of differential rotates at a high speed, causes fluid to get rid of on the breather plug inner chamber body, scurries out at the bridge bag inner high voltage environment oil that gets rid of on breather plug that descends.Scurry oil for a long time and can cause gear lubricant to reduce, cause the gear heat to cool off fast and cause gear, bearing to be ablated.And the oil that sprays influences the attractive in appearance of car load.
Summary of the invention
At the deficiency that prior art exists, technical problem to be solved in the utility model is, provides a kind of simple in structure, is convenient to make, and the reliability height solves present part axle assembly at a kind of anti-channeling oil formula breather plug of problems such as breather plug position oil spout.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of anti-channeling oil formula breather plug, be made up of the breather plug top cover that the ventilation stopper rod with inner chamber reaches and described ventilation stopper rod is adaptive, the inwall upper edge breather plug rod axis direction of described ventilation stopper rod is provided with the oil resistance step of a plurality of different sizes.
Above-mentioned anti-channeling oil formula breather plug, the described oil resistance step of being separated by are provided with and stop the make progress oil resistance angle of play of lubricant oil.
The advantage of the utility model anti-channeling oil formula breather plug is: the utility model anti-channeling oil formula breather plug, and it is made up of ventilation stopper rod and breather plug top cover, it is characterized in that: the architecture advances on the stopper rod inner chamber of ventilating has increased the oil resistance step of different levels; Oil gets rid of on inner chamber during work, and the oil resistance step is lived oil catch, effectively stops fluid to be scurried out to reduce in the bridge bag lubricant oil probability of scurrying out, and reduces the gear and the bearing ablation phenomenon that cause because of lack of lubrication; Save in the time of equilibrium air pressure with oil, guarantee the attractive in appearance of vehicle bridge and car load.
Description of drawings
Fig. 1 is the structural representation of traditional breather plug;
Fig. 2 is structural representation of the present utility model.
Embodiment
Reaching specific embodiment by reference to the accompanying drawings is described in further details the utility model;
As shown in Figure 1, traditional breather plug is made up of ventilation stopper rod 1 and breather plug top cover 2.Ventilation stopper rod inner chamber 3 is straight-through type, when high-speed gear rotates, gets rid of at the fluid of breather plug inner chamber 3 and will under high pressure be scurried out.Scurry oil for a long time and will have influence on the cooling of gear and lubricated, and the fluid of ejection has influence on the attractive in appearance of car load.
As shown in Figure 2, this a kind of anti-channeling oil formula breather plug, by having 2 one-tenths of the breather plug top covers that inner chamber 3 ventilation stopper rods 1 and ventilation stopper rod 1 join, the axial direction of the stopper rod 1 of ventilating in inwall 4 upper edges of the stopper rod 1 of ventilating is provided with the oil resistance step 5 of a plurality of different sizes.Be to improve the oil resistance effect, the oil resistance step 5 of being separated by is provided with and stops the make progress oil resistance angle 6 of play of lubricant oil.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
Claims (2)
1. an anti-channeling oil formula breather plug is made up of the breather plug top cover that the ventilation stopper rod with inner chamber reaches and described ventilation stopper rod is adaptive, and it is characterized in that: the inwall upper edge breather plug rod axis direction of described ventilation stopper rod is provided with the oil resistance step of a plurality of different sizes.
2. anti-channeling according to claim 1 oil formula breather plug is characterized in that: the described oil resistance step of being separated by is provided with and stops the make progress oil resistance angle of play of lubricant oil.
