[0002] Automobile wheel hub bearings are an important part of automobiles. Their main function is to bear the weight of the automobile and provide precise guidance for the rotation of the wheel hub. Wheel hub bearings need to bear both axial and radial loads, which is crucial to the driving performance and safety of the automobile.

[0003] For example, Chinese patent literature discloses an automobile wheel hub bearing [application number: 201621405789.X; authorization announcement number: CN206329638U], which includes an inner ring and an outer ring both of which are provided with flanges, and a sealing assembly is also provided between the inner ring and the outer ring, and the sealing assembly includes a set of sealing rings provided on the inner ring, and a frame positioned inside the sealing ring, and the outer end of the sealing ring is also bent and extended to have a lip ring that can abut against the inner wall of the outer ring, the outer wall of the inner ring is convexly provided with an annular protrusion, and the inner wall of the sealing ring is provided with an annular groove for the annular protrusion to be inserted and positioned.

[0004] The above-mentioned automobile wheel hub bearing can be accurately installed at one time, which improves work efficiency. However, it is prone to wear and corrosion during use, does not have high-strength function, and is also prone to temperature rise when the wheel hub bearing rotates. It cannot withstand high temperatures, which reduces the service life of the automobile wheel hub bearing. Moreover, it cannot be tightly connected with the automobile wheel hub connecting shaft, thereby not having the function of improving sealing. Therefore, after the wheel hub bearing is connected to the automobile wheel hub connecting shaft, the sealing with the wheel hub shaft cannot be guaranteed, and dust can easily enter the wheel hub bearing, which can easily affect the wheel bearing. Summary of the invention

[0005] The utility model aims to solve the above problems existing in the prior art and provide a high-strength automobile wheel hub bearing with good sealing performance and long service life.

[0007] The high-strength automobile wheel hub bearing can improve the strength of the automobile wheel hub bearing through the first connecting layer and the second connecting layer, making it more wear-resistant and less prone to wear and corrosion. When the temperature rises during long-term rotation, it will not be affected by the high temperature, thereby increasing the service life of the automobile wheel hub bearing.

[0008] In the above-mentioned high-strength automobile wheel hub bearing, the sealing assembly includes a tightening spring, which is movably sleeved on the surface of the connecting bolt, and the left end of the tightening spring is fixedly connected with a circular ring, and the inner wall of the circular ring is welded with a sleeve. By providing the sleeve, the connecting head can be protected so that the connecting head is not easily damaged. The inner wall of the sleeve is fixedly connected with a sealing sleeve, and the right end of the sealing sleeve penetrates into the inner cavity of the connecting head.

[0009] In the above-mentioned high-strength automobile wheel hub bearing, the right end of the tight spring is welded to the left side of the connecting flange, and the collar and the circular ring are both movably sleeved on the surface of the connecting head.

[0010] In the above-mentioned high-strength automobile wheel hub bearing, the second connecting layer includes a second corrosion-resistant layer, the inner wall of the second corrosion-resistant layer is hot-melt-connected to the surface of the first connecting layer, and the surface of the second corrosion-resistant layer is hot-melt-connected to a second wear-resistant layer.
