Description

Technical Field

[0001] This utility model relates to the field of automotive bearing technology, and in particular to a high-strength wheel hub bearing unit. Background Technology

[0002] Currently, in automotive chassis systems, the wheel hub bearing unit is the core component connecting the wheels and the vehicle body. It bears the vehicle's weight load, transmits driving torque and braking torque, and ensures the smooth rotation of the wheels.

[0003] During long-term use, existing wheel hub bearing units are prone to outer ring wobble and displacement due to complex radial loads, axial loads, and impact loads. This leads to a decrease in the stability of the bearing unit, which not only affects the rotational accuracy of the wheel but also accelerates the wear of parts, reduces the service life and strength of the bearing unit, and may even cause safety hazards. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-strength wheel hub bearing unit.

[0005] This utility model is achieved using the following technical solution: a high-strength wheel hub bearing unit, including a flange, an inner ring fitted on the flange, and an outer ring fitted on the flange, the outer ring being located outside the inner ring. A plurality of balls arranged in a circular array are provided between the outer ring and the inner ring. A plurality of cages arranged in a circular array are also provided between the outer ring and the inner ring. Each ball slides in contact with an adjacent cage. One side of the flange is provided with a plurality of anti-offset components arranged in a circular array to prevent the outer ring from loosening or shifting. Each anti-offset component is provided with reinforcing components to enhance its strength. A first limiting groove is formed on the cylindrical surface of the outer ring. A second limiting groove is formed on one side of the cylindrical surface of the outer ring. The anti-deviation component includes a first reinforcing plate fixedly installed on one side of the flange. A second reinforcing plate is fixedly installed on one side of the flange. One end of the first reinforcing plate extends to one side of the first limiting groove, and one end of the second reinforcing plate extends to one side of the second limiting groove. A limiting block is fixedly installed on one end of the first reinforcing plate and one end of the second reinforcing plate. One side of each limiting block extends into the interior of the adjacent first or second limiting groove.

[0006] Through the above technical solution, the first reinforcing plate and the second reinforcing plate in the anti-offset assembly are respectively embedded in the first and second limiting grooves of the outer ring through limiting blocks, which can play a radial and axial limiting role on the outer ring, effectively preventing the outer ring from loosening and offsetting during long-term use, and ensuring the stability of the bearing unit.

[0007] As a further improvement to the above scheme, both the first limiting groove and the second limiting groove are completely annular.

[0008] Through the above technical solution, the first and second limiting grooves arranged in annular shape can cooperate with the rotational movement of the outer ring, so that the limiting block always remains in the limiting state within the limiting groove and will not disengage due to the rotation of the outer ring, thereby further improving the anti-deviation effect.

[0009] As a further improvement to the above solution, each of the limiting blocks has multiple rolling grooves on three sides that are close to the adjacent first or second limiting groove. Each rolling groove has a sliding ball rotatably installed inside, and each sliding ball is in contact with the inner wall of the adjacent first or second limiting groove.

[0010] Through the above technical solution, the sliding ball can convert the sliding friction between the limiting block and the limiting groove into rolling friction, reduce the frictional resistance and wear between the two, ensure the smooth rotation of the outer ring, and at the same time not affect the anti-deviation effect.

[0011] As a further improvement to the above solution, the reinforcing component includes a reinforcing ring fixedly sleeved on the outer ring, and a limiting ring that is fixedly installed on the flange is rotatably sleeved on the cylindrical surface of the reinforcing ring.

[0012] With the above technical solution, the reinforcing ring is fixedly sleeved on the outer ring, and the limiting ring is fixed to the flange and rotatably sleeved on the reinforcing ring, which can further limit and support the reinforcing ring and the outer ring, enhance the structural strength of the outer ring, and reduce the deformation of the outer ring.

[0013] As a further improvement to the above solution, a third limiting groove is provided on the cylindrical surface of the reinforcing ring, a limiting groove is provided on the inner ring surface of the limiting ring, and one side of the inner ring of the limiting ring extends into the interior of the third limiting groove.

[0014] Through the above technical solution, the inner ring of the limiting ring is embedded in the third limiting groove of the reinforcing ring, which can play an axial limiting role for the reinforcing ring and the outer ring, prevent the reinforcing ring and the outer ring from moving axially, and further improve the stability and strength of the overall structure.

[0015] As a further improvement to the above solution, a protective groove is provided on the side of the reinforcing ring near the flange, and both the first reinforcing plate and the second reinforcing plate are located at the temporal part of the protective groove.

[0016] Through the above technical solution, the protective groove can protect the first and second reinforcing plates, prevent external impurities or collisions from damaging the reinforcing plates, and improve the strength and service life of the anti-displacement component.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention incorporates an anti-offset component and a reinforcing component. The anti-offset component effectively prevents the outer ring from loosening and shifting, while the reinforcing component further enhances the strength of both the outer ring and the anti-offset component. Together, they significantly improve the overall strength, stability, and service life of the wheel hub bearing unit, reducing the risk of failure caused by the loosening and shifting of the outer ring.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Please combine Figures 1-6This embodiment of a high-strength wheel hub bearing unit includes a flange 1, an inner ring 2 fitted on the flange 1, and an outer ring 3 fitted on the flange 1. The outer ring 3 is located outside the inner ring 2. A plurality of balls 4 arranged in a circular array are provided between the outer ring 3 and the inner ring 2. A plurality of cages 5 arranged in a circular array are also provided between the outer ring 3 and the inner ring 2. Each ball 4 slides and fits against the adjacent cage 5. A plurality of anti-offset components arranged in a circular array are provided on one side of the flange 1 to prevent the outer ring 3 from loosening and shifting. The anti-offset components are provided with reinforcing components to enhance the strength of the anti-offset components.

[0029] A first limiting groove 8 is provided on the cylindrical surface of the outer ring 3. A second limiting groove 9 is provided on one side of the cylindrical surface of the outer ring 3. The anti-deviation assembly includes a first reinforcing plate 601 fixedly installed on one side of the flange 1. A second reinforcing plate 602 fixedly installed on one side of the first reinforcing plate 601 is provided on one side of the flange 1. One end of the first reinforcing plate 601 extends to one side of the first limiting groove 8, and one end of the second reinforcing plate 602 extends to one side of the second limiting groove 9. A limiting block 603 is fixedly installed on one end of the first reinforcing plate 601 and one end of the second reinforcing plate 602. One side of each limiting block 603 extends into the interior of the adjacent first limiting groove 8 or second limiting groove 9.

[0030] The first reinforcing plate 601 and the second reinforcing plate 602 in the anti-offset assembly are respectively embedded in the first limiting groove 8 and the second limiting groove 9 of the outer ring 3 through the limiting block 603, which can play a radial and axial limiting role on the outer ring 3, effectively preventing the outer ring 3 from loosening and offset during long-term use, and ensuring the stability of the bearing unit.

[0031] Both the first limiting groove 8 and the second limiting groove 9 are complete annular structures.

[0032] The first limiting groove 8 and the second limiting groove 9 arranged in a ring can cooperate with the rotational movement of the outer ring 3 to keep the limiting block 603 in the limiting groove at all times, and will not be dislodged due to the rotation of the outer ring 3, thereby further improving the anti-deviation effect.

[0033] Each limiting block 603 has multiple rolling grooves on three sides that are close to the adjacent first limiting groove 8 or second limiting groove 9. Each rolling groove has a sliding ball 10 rotatably installed inside it, and each sliding ball 10 is in contact with the inner wall of the adjacent first limiting groove 8 or second limiting groove 9.

[0034] The sliding ball 10 can convert the sliding friction between the limiting block 603 and the limiting groove into rolling friction, reducing the frictional resistance and wear between the two, ensuring the smooth rotation of the outer ring 3, and at the same time not affecting the anti-deviation effect.

[0035] The reinforcing component includes a reinforcing ring 701 fixedly sleeved on the outer ring 3. A limiting ring 702, which is fixedly installed on the flange 1, is rotatably sleeved on the cylindrical surface of the reinforcing ring 701. A third limiting groove 11 is formed on the cylindrical surface of the reinforcing ring 701. A limiting groove is formed on the inner ring surface of the limiting ring 702. One side of the inner ring of the limiting ring 702 extends into the interior of the third limiting groove 11. A protective groove 12 is formed on the side of the reinforcing ring 701 near the flange 1. The first reinforcing plate 601 and the second reinforcing plate 602 are both located at the temporal part of the protective groove 12.

[0036] The reinforcing ring 701 is fixedly sleeved on the outer ring 3, and the limiting ring 702 is fixed to the flange 1 and rotatably sleeved on the reinforcing ring 701. It can further limit and support the reinforcing ring 701 and the outer ring 3, enhance the structural strength of the outer ring 3, and reduce the deformation of the outer ring 3.

[0037] The inner ring of the limiting ring 702 is embedded in the third limiting groove 11 of the reinforcing ring 701, which can axially limit the reinforcing ring 701 and the outer ring 3, prevent the reinforcing ring 701 and the outer ring 3 from axial movement, and further improve the stability and strength of the overall structure.

[0038] The implementation principle of a high-strength wheel hub bearing unit in this application embodiment is as follows: the first reinforcing plate 601 and the second reinforcing plate 602 are fixedly installed on the flange 1. When the flange 1 rotates, it will drive the first reinforcing plate 601 and the second reinforcing plate 602 to move accordingly, thereby driving the limiting block 603 to move synchronously. The limiting block 603 extends into the first limiting groove 8 and the second limiting groove 9 of the outer ring 3. At this time, the sliding ball 10 on the limiting block 603 is in contact with the inner wall of the first limiting groove 8 and the second limiting groove 9. As the outer ring 3 and the inner ring 2 rotate relative to each other, the sliding ball 10 rotates in the rolling groove, converting sliding friction into rolling friction, reducing the frictional resistance between the limiting block 603 and the limiting groove. This ensures the smooth rotation of the outer ring 3 and effectively prevents the outer ring 3 from shaking or shifting through the limiting effect of the limiting block 603 on the first limiting groove 8 and the second limiting groove 9.

[0039] The reinforcing ring 701 is fixedly sleeved on the outer ring 3 and will rotate together with the outer ring 3. The limiting ring 702 is fixedly installed on the flange 1 and rotates on the reinforcing ring 701. One side of the inner ring of the limiting ring 702 extends into the third limiting groove 11 of the reinforcing ring 701. During the rotation of the reinforcing ring 701, the limiting ring 702 plays an axial limiting role on the reinforcing ring 701 through the third limiting groove 11, preventing the reinforcing ring 701 and the outer ring 3 from axially moving.

[0040] In addition, the first reinforcing plate 601 and the second reinforcing plate 602 are located in the protective groove 12 of the reinforcing ring 701. The protective groove 12 surrounds and protects the reinforcing plate, reducing the damage to the reinforcing plate caused by external factors. At the same time, it enhances the structural stability of the reinforcing plate and prevents it from deforming under stress, thereby further ensuring the anti-displacement effect of the anti-displacement component and the strength of the overall structure.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
