The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. The following describes an embodiment of the present invention according to its overall structure.

Referring to fig. 1-4, the long-life automobile rotating shaft sealing element comprises a sealing element body 1, a through hole 2, a through hole 3, a groove 4, a wear-resistant layer 5, a heat-conducting layer 6, an oil tank 7, a seal lip 8, a micro oil pump 9, an oil pipe 10, a valve 11, a double-head oil pipe 12, a nozzle 13, a brush 14 and a filter screen 15, wherein the through hole 2 and the through hole 3 are respectively arranged at the top of the sealing element body 1, the filter screen 15 is arranged inside the through hole 2, the wear-resistant layer 5 is arranged on the inner wall of the through hole 3, the heat-conducting layer 6 is arranged on one side of the wear-resistant layer 5, the groove 4 is arranged inside the sealing element body 1, the oil tank 7 and the seal lip 8 are respectively arranged on one side inside the groove 4, the oil pipe 10 penetrating through the top of the sealing element body 1 is connected to the top of the oil tank 7, the valve 11 is arranged on the outer surface of the oil pipe 10, the micro oil pump 9 is arranged below the inside of the oil tank 7, the double-head oil pipe 12 is connected to the double-head oil pump 9, one end of the double-head oil pipe 12 is connected with a spray head 13, and a brush 14 is arranged at the oil spraying end of the spray head 13.

Please refer to fig. 1, 3 and 4, the plurality of groups of through holes 2 are arranged, and the plurality of groups of through holes 2 are symmetrically arranged by taking the longitudinal axis of the sealing element body 1 as the center, so that heat can be conveniently dissipated from a plurality of angles, and the double-end oil pipe 12 is made of heat-resistant materials, so that the temperature of the lubricating oil cannot be increased.

Please refer to fig. 2-4, the four sets of brushes 14 are provided, and the four sets of brushes 14 are made of fiber material, so that the material is light, the flexibility is high, and the outer surface of the valve 11 is provided with anti-slip lines to increase the friction force and prevent slipping.

The working principle is as follows: when the sealing element and the rotating shaft rotate at high speed, the internal heat is dissipated to the inside of the groove 4 through the heat conduction layer 6, the external cold air enters the inside of the groove 4 through the group of through holes 2 and carries the internal heat to the other group of through holes 2, and then the heat is dissipated, and then under the action of the filter screen 15, the external dust can be blocked, when the sealing element and the rotating shaft rotate at high speed, the friction coefficient is increased through the action of the wear-resistant layer 5, secondly, through the action of the miniature oil pump 9, the oil inside the oil tank 7 is sprayed out from the spray head 13 through the double-end oil pipe 12, the sprayed oil is adhered on the brush 14, because the brush 14 is made of fiber materials, the rotating shaft cannot be scraped to be damaged, under the action of lubricating oil, the friction force is further reduced, the service lives of the sealing element and the rotating shaft are long, when the oil amount in the oil tank 7 is insufficient, by opening the valve 11, the external oil pipe is connected with the oil pipe 10, and the valve 11 is closed after the sufficient amount of oil is added into the oil tank 7.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
