Description

Technical Field

[0001] The utility model relates to the technical field of oil seals, in particular to an automobile wheel hub oil seal which can be disassembled and assembled multiple times. Background Art

[0002] Automobile oil seal is one of the most commonly used accessories in automobile maintenance. Oil seal is also called oil retaining ring. All parts of automobile mechanisms equipped with rolling bearings or sliding bearings need to be installed with oil seals to prevent the leakage or seepage of lubricating oil or grease, and at the same time prevent the infiltration of dust or sludge, maintain good lubrication conditions of rolling or sliding friction parts, and extend service life. Automobile drive axle oil seals are mainly divided into driving gear oil seals, inner and outer wheel hub oil seals, bearing seat oil seals, half-axle oil and steam seals, etc.

[0003] When the wheel hub oil seal needs to be removed for automobile maintenance, the existing wheel hub oil seal is usually designed in L-shape or C-shape, which makes the inner and outer oil seals stuck to each other and difficult to remove. Forced removal can easily cause the wheel hub oil seal to be damaged and lose a certain degree of sealing, so it needs to be replaced. The operation is time-consuming and labor-intensive, and the cost may increase due to damage. Utility Model Content

[0006] By adopting the above-mentioned technical scheme, the inner frame can be directly inserted into the outer frame, and the bends on the inner frame and the outer frame will not affect the insertion and removal of the inner frame. Then the sealing plate is inserted into the outer frame. At this time, the bottom end of the outer frame passes through the through hole, and the sealing plate passes through the slot, so that the sealing plate is connected to the outer frame. At the same time, the sealing plate limits the inner frame to prevent the inner frame from falling off. Then, the bolts are tightened to complete the limitation between the sealing plate and the outer frame. When disassembling, you only need to remove the bolts. Since the inner circle of the sealing plate is bent downward to facilitate the force to pull it out, the sealing plate and the inner frame are taken out in turn to complete the disassembly work.

[0007] Furthermore, the sealing plate is detachably connected to the outer frame.

[0008] By adopting the above technical solution, the sealing plate is inserted into the outer frame, and then the bolts are tightened to complete the limiting between the sealing plate and the outer frame.

[0011] Furthermore, the bottom of the outer frame is adapted to the through hole.

[0012] By adopting the above technical solution, the sealing plate is inserted into the outer frame, and the bottom end of the outer frame passes through the through hole, and the sealing plate passes through the slot, so that the sealing plate is connected to the outer frame.

[0013] Furthermore, an outer oil seal is connected to the top of the outer frame, an oil seal lip is connected to one side of the top of the outer oil seal, and a spring is connected to the outer surface of the oil seal lip.

[0014] By adopting the above technical solution, the outer oil seal, the oil seal lip and the spring are arranged, so as to increase the sealing performance of the wheel hub and effectively avoid the leakage of lubricating oil and grease from the wheel hub.

[0015] Furthermore, the inner frame is located below the outer frame, and an inner oil seal is connected to the bottom of the inner frame, and a dust lip is connected to one side of the inner oil seal.

[0016] By adopting the above technical solution and arranging the inner oil seal and the dustproof lip, the external dust can pass through the oil seal and enter the lubricating oil or grease to increase the wear.

[0017] Furthermore, a rib is connected to the bottom of the sealing plate.

[0018] By adopting the above technical solution, the ribs are against the outer frame, and the ribs are triangular, so as to support the sealing plate and increase the structural strength of the sealing plate.

[0019] Furthermore, the ribs are provided in plurality, two in a group, and the ribs are divided into a plurality of groups in total, and the plurality of groups of ribs are arranged in a circular array.

[0020] By adopting the above technical solution, the connection points between the sealing plate and the outer frame are supported by multiple ribs, thereby effectively increasing the structural strength of the sealing plate and further extending the service life of the sealing plate.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1:

[0032] An automobile wheel hub oil seal that can be disassembled and assembled multiple times, such as Figure 1-Figure 5As shown, it includes an exoskeleton 1 and an inner frame 2. A slot 9 and a sealing plate 5 are respectively provided at the bottom of the exoskeleton 1. The sealing plate 5 is detachably connected to the exoskeleton 1. A through hole 13 is opened on the top of the sealing plate 5. The bottom of the exoskeleton 1 is adapted to the through hole 13. The sealing plate 5 is inserted into the exoskeleton 1. At this time, the bottom end of the exoskeleton 1 passes through the through hole 13, and the sealing plate 5 passes through the slot 9, so that the sealing plate 5 is connected to the exoskeleton 1; the inner circle of the sealing plate 5 is bent downward, and the inner circle of the sealing plate 5 is bent downward to facilitate force application; a nut 12 passes through one side of the sealing plate 5, and a bolt 10 is provided between the sealing plate 5 and the exoskeleton 1. The bolt 10 is tightened to complete the limiting between the sealing plate 5 and the exoskeleton 1.

[0033] See also Figure 1-Figure 4 In the above embodiment, an outer oil seal 3 is connected to the top of the outer skeleton 1, an oil seal lip 6 is connected to one side of the top of the outer oil seal 3, and a spring 7 is connected to the outer surface of the oil seal lip 6 to prevent leakage of lubricating oil or grease; the inner skeleton 2 is located below the outer skeleton 1, an inner oil seal 4 is connected to the bottom of the inner skeleton 2, and a dustproof lip 8 is connected to one side of the inner oil seal 4 to reduce the entry of external dust.

[0034] Embodiment 2:

[0035] On the basis of the above-mentioned embodiment 1, although the disassembly and assembly operation is simple and convenient by setting the sealing plate 5, the slot 9, the bolts 10, the nuts 12 and the through holes 13, and the oil seal is not easily damaged, so it can be disassembled and assembled many times; but the through holes 13 are opened on the sealing plate 5, which reduces the structural strength of the sealing plate 5, and the inner skeleton 2 easily applies downward pressure to the sealing plate 5, causing the sealing plate 5 to bend and deform; now by setting the ribs 11, the structural strength can be increased.

[0036] See also Figure 2 , 4 and Figure 5 In the above embodiment, a rib 11 is connected to the bottom of the sealing plate 5. There are multiple ribs 11, two in a group, and a total of multiple groups. The multiple groups of ribs 11 are in a circular array shape, and the ribs 11 are respectively abutted against the outer frame 1, and the ribs 11 are triangular, so as to support the sealing plate 5 and increase the structural strength of the sealing plate 5.

[0037] The implementation principle of the utility model is as follows: first, during assembly, the staff directly inserts the inner frame 2 into the outer frame 1, and the bends on the inner frame 2 and the outer frame 1 will not affect the insertion and removal of the inner frame 2. Then the staff inserts the sealing plate 5 into the outer frame 1. At this time, the bottom end of the outer frame 1 passes through the through hole 13, and the sealing plate 5 passes through the slot 9, so that the sealing plate 5 is connected to the outer frame 1. At the same time, the sealing plate 5 limits the inner frame 2 to prevent the inner frame 2 from falling off. Then the staff tightens the bolts 10 to complete the limit between the sealing plate 5 and the outer frame 1;

[0038] During disassembly, the staff first removes the bolts 10. Since the inner circle of the sealing plate 5 is bent downward to facilitate the application of force, the staff then places their hands on the inner circle of the sealing plate 5 and applies force downward, thereby pulling the sealing plate 5 out of the outer frame 1. After that, the staff can directly take out the inner frame 2 to complete the disassembly work.
