Problems solved by technology

Such an exhaust structure has the following defects: 1. The rubber venting plug is easy to block, resulting in excessive pressure in the hub cavity and oil leakage; 2. The discharged oil, gas and oil mist are easy to absorb dust on the end cap and cause the end surface of the hub to become dirty; 3. External moisture and dust may enter the hub cavity through the exhaust plug and contaminate the lubricating oil

Embodiment Construction

[0019] The lubricating oil mist discharge system of the axle hub cavity such as figure 1 As shown, it includes an axle 1 and a hub 2 installed at the end of the axle 1 , the end of the axle 1 has an end hole 3 , and the hub 2 is provided with a hub chamber 5 sealed by a hub end cover 4 . In the end hole 3 is covered with an exhaust cover 6, the exhaust cover 6 is figure 2 In the shown lubricating oil mist exhaust cap, the periphery of the exhaust cap 6 is closely matched with the inner wall of the end hole 3 , so that the exhaust cap 6 is firmly fixed in the end hole 3 .

[0020] see figure 2 , The lubricating oil mist exhaust cover 6 includes a cover body 7, the cover body 7 can be formed by metal stamping or machining, and the cover body 7 is provided with exhaust holes 8 running through the end faces of the two ends of the cover body. An exhaust valve core 9 covering the exhaust hole 8 is arranged on one end surface of the cover body 7 . exist figure 1 In the shown lu...

Abstract

The invention discloses a lubricating oil mist exhaust cover of an axle hub cavity. The lubricating oil mist exhaust cover comprises a cover body. An exhaust hole penetrating through the two end surfaces of the cover body is formed in the cover body. The invention further discloses a lubricating oil mist exhaust system of the axle hub cavity. The system comprises an axle and a hub mounted at the end of the axle. An end hole is formed in the end of the axle. The hub is provided with the hub cavity formed by a hub end cover in a sealing mode. The lubricating oil mist exhaust cover covers the endhole in the axle. The periphery of the lubricating oil mist exhaust cover and the inner wall of the end hole are in tight fit. The lubricating oil mist exhaust cover and system of the axle hub cavityhave the advantages that oil gas and oil mist in the hub cavity are exhausted into the axle through the exhaust cover, and the end surface of the hub is not smudged; and compared with an adopted rubber vent plug in the prior art, gas exhausting is smoother, the risk of blocking does not exist, the oil gas and the oil mist can be exhausted out of the hub cavity through the exhaust cover in time, and the risk that external moisture and dust enter the hub cavity is greatly lowered.

Description

technical field [0001] The invention relates to a trailer axle, in particular to a lubricating oil mist discharge system for discharging the lubricating oil mist in the hub cavity at the axle end of the axle to the hub cavity. Background technique [0002] There are two types of lubrication for trailer axles: grease lubrication and oil lubrication. Oil-lubricated axles have the advantages of sufficient lubrication and good heat dissipation, and are widely used. However, when the oil-lubricated axle is running, due to the rotation of the bearing and the heating of the brake friction, the lubricating oil in the hub cavity will thermally expand and gasify to produce oil, gas and oil mist. The oil, gas and oil mist must be discharged from the hub in time, otherwise it will cause The pressure in the hub cavity increases to cause oil leakage accidents. For this reason, in the prior art, a rubber venting plug is installed on the hub end cap, and the oil gas and oil mist generated...
