[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4The application discloses a high-strength wheel hub, which comprises a wheel hub body, a connecting piece and a protection assembly, wherein the wheel hub body comprises an outer hub, a center ring and a connecting beam, the center ring is arranged concentrically in the outer hub, the connecting beam connects the outer hub and the center ring, the outer side of the center ring is provided with a groove, the center ring is further provided with a plurality of groups of connecting holes penetrating through the groove, the protection assembly comprises a cover plate and a connecting pipe, the outer side of the center ring is further provided with the connecting piece connected with the connecting pipe, and the outer diameter of the cover plate is larger than the outer diameter of the groove.

[0024] During vehicle driving, the wheel hub needs to bear the weight from the vehicle body, the longitudinal force generated by driving acceleration and braking and the lateral force during turning. The connecting beam is a key structure for connecting the outer hub and the center ring, and the two ends thereof are relatively thick. When external force acts, stress is concentrated on the connecting beam. The two thick ends are like two solid "fortresses", which can effectively disperse and bear the stress, avoid structure damage caused by excessive local stress, greatly improve the overall structural strength of the wheel hub and guarantee the driving safety of the vehicle.

[0025] When the protection assembly is installed, the connecting pipe is first aligned with the connecting piece on the outer side of the center ring, and the screw nut is well protected.

[0026] The O-shaped holes and V-shaped holes arranged uniformly on the connecting beam play a key role in lightening. The holes remove part of the redundant material without damaging the overall mechanical coherence of the connecting beam. The metal around the O-shaped holes and V-shaped holes will produce stress redistribution phenomenon when stressed, and the surrounding material will cooperatively share the force originally borne by the removed material, so that the strength of the wheel hub is maintained, the mechanical performance of resisting external force is not weakened, the vehicle control is more flexible, and the energy consumption is lower.

[0027] In this embodiment, the connecting piece comprises a screw rod 6, a fixed seat 7, an elastic piece and a clamping block 8. The fixed seat 7 is connected with the center ring 2. The fixed seat 7 is provided with the screw rod 6 at an end away from the center ring 2. The fixed seat 7 is further provided with movable grooves at two sides. The elastic piece is connected with the inner wall of the movable groove and the clamping block 8 at two ends. The connecting pipe 5 is provided with a receiving groove matched with the fixed seat 7. The receiving groove is further provided with a screw groove matched with the screw rod 6 at the center. The receiving groove is further provided with a clamping groove matched with the clamping block 8 at two sides. The fixed seat 7 of the connecting piece is stably connected with the center ring 2. The screw rod 6 on the fixed seat 7 is inserted into the screw groove in the receiving groove of the connecting pipe 5. In this insertion process, the hemispherical clamping block 8 in the movable groove at two sides of the fixed seat 7 is extruded by the inner wall of the connecting pipe 5, compressing the spring 9 and the telescopic rod 10. The clamping block 8 is retracted into the movable groove. When the connecting pipe 5 is completely inserted, so that the clamping block 8 is just aligned with the clamping groove at two sides of the receiving groove, the spring 9 is quickly rebounded with the support of the telescopic rod 10, and the hemispherical clamping block 8 is bounced into the clamping groove. Thus, the connecting pipe 5 is firmly locked on the fixed seat 7, so that the cover plate 4 is stably covered above the groove of the center ring 2. Since the outer diameter of the cover plate 4 is larger than the outer diameter of the groove, once the installation is completed, the cover plate 4 is like a solid "shield", which strictly blocks the invasion of dust, water vapor, sand and other foreign matters into the groove. In daily driving, the dust raised by the road, the water vapor in the rain, and the sand splashed cannot contact the nut in the groove, eliminating the hidden danger of nut corrosion and wear caused by foreign matter erosion and friction, and effectively guaranteeing the service life of the nut and the whole hub and vehicle body connection structure, and maintaining the long-term stability and reliability of the connection between the two;

[0028] When it is necessary to disassemble the protection assembly, for example, to check, maintain or replace the nut, a suitable tool is inserted into the unlocking groove 11 at an end of the cover plate 4 away from the connecting pipe 5, and an external force is applied. The external force pushes the clamping block 8, overcomes the elastic force of the spring 9, and makes the clamping block 8 come out of the clamping groove. The connecting pipe 5 is unlocked, and at this time, the connecting pipe 5 can be easily pulled out, and the cover plate 4 can be removed, which is convenient for subsequent operation.
