Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Such as figure 1 , image 3 As shown, there is a vent hole on the shell of the existing drive axle housing 1, and the vent structure of the air plug is installed on the vent hole. The air plug structure is composed of the following components: plug body 2, spring 3, plug cap 4, cover sheet 5 and decompression air chamber 6. The decompression air chamber 6 is welded on the position of the air plug of the axle housing. The decompression air chamber 6 is a hollow approximately rectangular cavity, and one side of the bottom protrudes an air intake channel to the inside of the axle housing. At this time, the high-temperature airflow in the drive axle housing 1 enters the decompression chamber 6 from the slender air intake passage, and the air pressure in the decompression chamber is relieved, and the lubricating oil settles in the decompre...

The invention relates to an air plug structure of a drive axle. A housing of an automobile drive axle is provided with an air plug opening which is provided with air plug modules including a plug body, a spring and a plug cap, the plug body is inserted into the air plug opening on the housing, the spring is arranged between the plug body and the plug cap, a decompressing air chamber is arranged at the position of the air plug opening on the housing and is communicated with the air plug opening and the inner cavity of the housing. The air plug structure effectively prevents a gear from throwing lubricating oil to an air outlet of the air plug to cause the problem of oil expelling, also guarantees the timely discharge of high temperature gas, meets the lubricating demand and realizes an excellent ventilation effect, thus the damage to parts inside the housing is reduced, the service life of the drive axle is accordingly prolonged, and the failure rate and the maintenance cost of an axle are both lowered.
Description
technical field [0001] The invention relates to the technical field of automobile drive axles, and more specifically relates to a drive axle air plug structure. Background technique [0002] When the automobile drive axle is running, the internal air pressure of the axle housing is higher than the external air pressure due to the temperature rise of the gear oil. In order to make the internal and external air pressure consistent, it is usually necessary to add a ventilation structure so that the gas can be discharged smoothly. See figure 1 and figure 2 , There is a ventilation hole on the outer shell of the axle housing 1, and the ventilation structure of the air plug is installed on the ventilation hole. The structure of the air plug is composed of the following components: plug body 2, spring 3, plug cap 4, and cover sheet 5. When the internal air pressure of the axle housing is higher than the external air pressure and the pressure of the spring, the internal high-pres...
