Description

Technical Field

[0001] This utility model relates to the technical field of wheel hub shaft structure, specifically a self-detachable wheel hub shaft structure. Background Technology

[0002] Wheel hub bearings are components used in automobile axles to bear weight and provide precise guidance for the transmission of the wheel hub. During the operation of a car, wheel hub bearings must withstand axial force, radial force, and bending moment generated when the car turns.

[0003] For example, Chinese Patent CN211693225U discloses an automotive wheel hub bearing, belonging to the field of automotive parts technology. It solves the problems of unstable rotation and short service life in existing automotive wheel hub bearings. This automotive wheel hub bearing includes an outer ring and an inner ring. Two sets of corresponding inner and outer cages are provided between the outer surface of the inner ring and the inner surface of the outer ring. The inner cage has an inner annular groove, and the outer cage has an outer annular groove. Multiple steel balls are arranged in both the inner and outer annular grooves. A limiting assembly device is provided between the outer cage and the inner ring to prevent the steel balls in the outer annular groove of the outer cage from falling out of the outer annular groove. This utility model has a reasonable and simple structural design and a stable assembly structure. The smooth relative rotation of the outer and inner rings of the bearing results in a stable overall structure and long service life for the wheel hub bearing. However, traditional wheel hub bearings do not have designated disassembly points on the bearing surface, requiring tools to be used to knock the bearing apart. This disassembly process can easily cause multiple damages to the bearing, affecting subsequent maintenance. Therefore, a self-disassembling wheel hub shaft structure is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a self-detachable hub shaft structure, which offers advantages such as convenient disassembly and solves the problem of inconvenient bearing disassembly in traditional designs.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goal of convenient disassembly, this utility model provides the following technical solution: a self-detachable hub shaft structure, comprising:

[0008] A connecting flange, wherein a plurality of bolt holes are provided on the outer surface of the connecting flange;

[0009] The bearing outer ring has grooves on both outer surfaces, and a stop block is provided inside the groove, and the stop block is the same size as the groove.

[0010] Preferably, a fixing bolt is installed inside the bolt hole, and the connecting flange is installed and fixed by the fixing bolt.

[0011] Preferably, the inner side of the outer ring of the bearing is provided with a storage groove for storing the stop block above the inner wall of the slot, and the stop block is moved to store it in the storage groove.

[0012] Preferably, a guide rod is fixedly installed on the inner wall of the storage slot, and one end of the guide rod is inserted into the inside of the stop block. The stop block is slidably connected to the guide rod. As the stop block is pushed into the storage slot, it will slide along the guide rod.

[0013] Preferably, a first retaining ring and a second retaining ring are sleeved at both ends of the guide rod, and a return spring is sleeved on the outer surface of the guide rod between the first retaining ring and the second retaining ring. During the movement of the stop block, the first retaining ring will be driven along the guide rod to squeeze the return spring.

[0014] Preferably, the outer surface of the stop block is provided with a groove, and the stop block is moved by the groove.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a self-detachable hub axle structure, which has the following advantages:

[0017] By creating slots on both sides of the outer ring surface of the bearing, with blocks inside the slots for filling, when disassembly is required, the blocks can be pushed upwards to open the slots, making it easy to insert tools for positioning. Then, the bearing can be pulled outwards for disassembly, which is convenient and avoids hitting the bearing, reducing damage to the bearing during disassembly. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 The present invention provides the following technical solution: a self-detachable hub shaft structure, comprising: a connecting flange 1, wherein a plurality of bolt holes 11 are provided on the outer surface of the connecting flange 1, and fixing bolts are installed inside the bolt holes 11, and the connecting flange is installed and connected by the fixing bolts; the outer surfaces of both sides of the bearing outer ring 2 are provided with slots 21, and the slots 21 are provided with blocks 22, and the blocks 22 are the same as the slots 21.

[0025] In this embodiment, a storage groove for accommodating the stop block 22 is provided above the inner wall of the slot 21 inside the bearing outer ring 2. A guide rod 23 is fixedly installed on the inner wall of the storage groove, and one end of the guide rod 23 is inserted into the stop block 22. The stop block 22 is slidably connected to the guide rod 23. A groove is provided on the outer surface of the stop block 22. Pushing the two stop blocks 22 on both sides of the bearing outer ring 2 upward opens the slot 21, making it convenient to insert tools for positioning. Then, the bearing is pulled outward for disassembly, which is more convenient and avoids hitting the bearing, reducing the damage to the bearing during disassembly.

[0026] The guide rod 23 is fitted with a first retaining ring 24 and a second retaining ring 25 at both ends. A return spring 26 is fitted on the outer surface of the guide rod 23 between the first retaining ring 24 and the second retaining ring 25. When the stop block 22 is pushed upward, it will drive the first retaining ring 24 to slide along the guide rod, and the first retaining ring 24 will squeeze the return spring 26 on the surface of the guide rod 23.

[0027] The working principle of this embodiment is as follows:

[0028] When it is necessary to disassemble the wheel hub bearing, push the two side blocks 22 on the outer ring 2 surface of the bearing upward to open the slot 21, so that the tool can be inserted for limiting. Then pull the bearing outward to disassemble it. This is more convenient and avoids hitting the bearing, reducing the damage to the bearing during disassembly.

[0029] As the stop block 22 is pushed upward, it will cause the first retaining ring 24 to slide along the guide rod. The first retaining ring 24 will press the return spring 26 on the surface of the guide rod 23. When the tool is disengaged from the slot 21, the return spring 26 will push the stop block 22 downward to fill the slot 21.
