Description
Technical Field
The utility model relates to an automobile wheel hub annex, specifically speaking are automobile wheel hub sealing mechanism.
Background
At present, a sealing device for an automobile hub of a certain model is formed by stamping a plate with the thickness of 1.5mm, and the part of the sealing device, which is in contact with the hub, is sealed by adopting an oil-proof impregnated paper pad; in the use process of a real vehicle, as the hub cover is thin, the contact surface of the bolt and the hub cover is easy to deform under the specified torque in the bolt tightening process, the local pressure is increased, and the oil-proof impregnated paper pad is pressed and fed, so that the sealing performance is reduced; on the other hand, the hub cover deforms, and the portion between the bolts warps, so that the pressure is reduced, and the sealing performance is lowered. The rolling bearing is arranged in the hub, after the sealing performance is reduced, lubricating grease is thrown out, the periphery of a hub cover is fully stained with oil sludge, the sensing performance is poor, and the quantity of the lubricating grease in a hub cavity is insufficient in severe cases; external rainwater, dust and the like enter the hub cavity, and the bearing loses effectiveness such as pitting corrosion, peeling and the like.
Disclosure of Invention
The utility model aims at overcoming the not enough of existence among the prior art, provide an automobile wheel hub sealing mechanism that can improve sealing performance.
According to the technical scheme provided by the utility model, the automobile hub sealing mechanism comprises a hub cover and a sealing washer; the hub cover comprises a hub cover body, a hub cover connecting ring and a connecting ring flanging, wherein the hub cover body is integrally connected to the inner circle of the hub cover connecting ring; the reinforcing gasket is provided with a reinforcing gasket mounting hole; the hub cover connecting ring is characterized in that a reinforcing gasket is arranged on the end face of the hub cover connecting ring corresponding to one side of the connecting ring flanging, a sealing gasket is arranged on the other end face of the hub cover connecting ring, and fastening bolts are arranged in the reinforcing gasket mounting hole, the connecting ring mounting hole and the sealing gasket mounting hole, so that the reinforcing gasket and the sealing gasket are clamped tightly by the hub cover connecting ring.
The sealing washer is an oil-resistant impregnated paper washer.
The thickness of strengthening the packing ring is 3~4 mm.
The utility model enhances the rigidity of the hub cover at the contact part of the hub cover and the fastening bolt, improves the sealing capability of the hub cover and reduces the failure risk; the utility model has the advantages of simple structure, low manufacturing cost, convenient installation and easy popularization.

Detailed Description
The present invention will be further described with reference to the following specific embodiments.
The utility model discloses an automobile hub sealing mechanism, which comprises a hub cover 2 and a sealing washer 3; the sealing washer 3 is provided with a sealing washer mounting hole 31, the hub cover 2 comprises a hub cover body 21, a hub cover connecting ring 22 and a connecting ring flange 23, the hub cover body 21 is integrally connected to the inner circle of the hub cover connecting ring 22, the connecting ring flange 23 is integrally connected to the outer circle of the hub cover connecting ring 22, the connecting ring flange 23 is arranged on the same side of the hub cover body 21, and the hub cover connecting ring 22 is provided with a connecting ring mounting hole 24; the reinforced gasket is characterized by further comprising a reinforced gasket 1, wherein a reinforced gasket mounting hole 11 is formed in the reinforced gasket 1; the end face of the hub cover connecting ring 22 corresponding to one side of the connecting ring flanging 23 is provided with a reinforcing gasket 1, the other end face of the hub cover connecting ring 22 is provided with a sealing gasket 3, and fastening bolts are installed in the reinforcing gasket installing hole 11, the connecting ring installing hole 24 and the sealing gasket installing hole 31, so that the reinforcing gasket 1 and the sealing gasket 3 clamp the hub cover connecting ring 22.
The sealing washer 3 is an oil-impregnated paper washer.
When the hub is used, when the reinforcing washer 1 is applied with axial force by the fastening bolt, the reinforcing washer 1, the hub cover 2 and the sealing washer 3 are pressed tightly and attached to the plane of the hub. At this time, the reinforcing washer 1 is added at the compression position of the fastening bolt, so that the rigidity of the system is increased, the hub cover connecting ring 22 cannot deform, the pressure distribution is more uniform, and the sealing performance is greatly improved.
