Description

Technical Field

[0001] The utility model relates to a wheel hub, in particular to an anti-slip steel wheel hub. Background Art

[0002] The wheel hub is an important component of the tire installed on the vehicle. The wheel hub is also related to the braking system and transmission system of the vehicle. The common wheel hubs on vehicles are generally divided into steel wheel hubs and aluminum wheel hubs.

[0003] In the prior art, for example, there is a reinforced anti-dropping wheel hub with announcement number CN219947765U, in which a reinforcing plate is arranged to cover one side of the wheel hub, so that the connection between the wheel hub and the axle can be shielded, so that the bolts on the wheel hub are not easy to fall off during the driving of the car, so that the wheel hub is firmly installed on the axle, and the wheel hub will not fall off during the driving of the car, and the reinforcing plate is installed on one side of the wheel hub by bolts and clamping, so as to increase the strength of the wheel hub.

[0004] However, there are still some shortcomings. For example, although the connection between the wheel hub and the axle can be shielded by setting a reinforcement plate, thereby preventing the bolts from falling off during the driving of the vehicle, the problem of the bolts loosening due to vibration during the driving of the vehicle is not solved. Although this can prevent the bolts from falling off, the firmness of the connection between the wheel hub and the vehicle will be reduced when the bolts are loosened. If the vehicle continues to drive, the wheel is likely to detach, which may cause a safety accident. At the same time, the wheel is likely to deviate or detach from the wheel hub due to tire leakage or insufficient tire pressure during use, which may also easily cause a safety accident.

[0025] This embodiment mainly describes the structure of an anti-slip steel hub, which is as follows:

[0026] like Figure 1-Figure 6As shown, an anti-slip steel hub comprises a hub body 1, a spoke 2 is arranged in the hub body 1, a first through hole 9 is opened at the center of the spoke 2; and a plurality of first nuts 3 are axially arranged on the spoke 2 with the first through hole 9 as the center, the first nuts 3 are all located on the outside of the first through hole 9, the first nut 3 is provided with a sleeve 31 on the side away from the spoke 2, and an external thread 32 is arranged on the outer wall of the sleeve 31; a second nut 4, a plurality of second nuts 4 are provided, and the second nuts 4 are respectively rotatably installed on the first nut 3, the first nut 3 and the second nut 4 are coaxially arranged, and the second thread The nut 4 is provided with a groove 41 matching with the sleeve 31 on the side close to the first nut 3, and an internal thread 42 is provided on the inner wall of the groove 41 and the side close to the outer wall of the sleeve 31, and the sleeve 31 and the groove 41 are screwed together through the external thread 32 and the internal thread 42; a clamping assembly, the clamping assembly is provided with two, and the clamping assemblies are respectively installed on the side walls on the left and right sides of the hub body 1, and the clamping assembly includes a first clamping ring 5, the first clamping ring 5 is installed on the side wall of the hub, and the first clamping ring 5 is provided with a step 10 on the side away from the hub body 1; a second clamping ring 6, the second clamping ring 6 is installed A plurality of second through holes 7 are provided on the first clamping ring 5 and the second clamping ring 6, and a plurality of threaded holes corresponding to the second through holes 7 are provided on the first clamping ring 5. The second clamping ring 6 is bolted to the first clamping ring 5 through the cooperation of the second through holes 7 and the threaded holes. At the same time, a plurality of mounting holes 61 are provided on a side wall of the second clamping ring 6 close to the first clamping ring 5, and a first limiting ring 11 is provided on the top of each mounting hole 61. The mounting hole 61 is axially arranged along the second clamping ring 6, and then a pressure column 8 is slidably arranged in each mounting hole 61, and the top of the pressure column 8 is rounded. A protective layer 81 is arranged on the outer wall of the pressure column 8, and the protective layer 81 is made of rubber. A second limiting ring 12 is arranged at the bottom of the pressure column 8. At the same time, a receiving groove 14 is opened in each of the multiple pressure columns 8, and a spring 13 is installed in the receiving groove 14, and one end of the spring 13 is connected to the mounting hole 61 and the other end is connected to the top of the receiving groove 14. Due to the setting of the step 10, a limiting groove is formed between the first clamping ring 5 and the second clamping ring 6, and the pressure column 8 is located in the limiting groove. The hub body 1 is a steel hub in the prior art, so it is not described in detail in this application.

[0027] When the wheel hub body 1 is connected to the wheel hub axle on the vehicle, the staff first aligns the first nut 3 and the second nut 4 on the spoke 2 with the connecting holes on the wheel hub axle, and then screws the bolts from the second nut 4 and passes through the first nut 3 to connect with the connecting holes on the wheel hub axle. As the bolts are tightened, the wheel hub body 1 can be tightly connected to the wheel hub axle, and then the second nut 4 is rotated to make the sleeve 31 installed on the first nut 3 be screwed into the groove 41 in the second nut 4 through the external thread 32 and the internal thread 42 in the groove 41. In this way, the second nut 4 presses the first nut 3. In this way, the coordinated use of the first nut 3 and the second nut 4 can lock and prevent the bolt from loosening. At the same time, the coordinated use of the sleeve 31 and the groove 41 and the external thread 32 and the internal thread 42 improves the clamping effect of the second nut 4 on the first nut, thereby avoiding the loosening of the bolt, thereby improving the firmness of the connection between the wheel hub and the wheel hub axle of the vehicle, thereby improving the safety of the vehicle.

[0028] When installing the tire, the beads on both sides of the tire are installed on the steps 10 of the first clamping ring 5, and then the second clamping ring 6 is installed on the first clamping ring 5 by bolts. As the bolts are tightened, the second clamping ring 6 can clamp and fix the bead of the tire, which can avoid the problem of the tire running off the track or detaching from the wheel hub due to air leakage or insufficient tire pressure, thereby further improving the safety of the vehicle. The pressure column 8 installed on the second clamping ring 6 can press the bead of the tire through the cooperation of the spring 13, which can further improve the clamping effect on the bead of the tire. The coordinated use of the spring 13, the pressure column 8 and the mounting hole 61 can also prevent the pressure column 8 from pressing the tire bead too hard and causing damage to the tire bead. At the same time, the top of the pressure column 8 is rounded and a protective layer 81 made of rubber is provided on the surface of the pressure column 8 to further protect the tire bead, thereby extending the service life of the tire. The first limiting ring 11 and the second limiting ring 12 are provided to prevent the pressure column 8 from detaching from the mounting hole 61. At the same time, a receiving groove 14 is provided in the pressure column 8 and the spring 13 is in the receiving groove 14 to improve the stability of the spring 13, thereby improving the pressure effect of the pressure column 8 on the tire bead.
