Description

Technical Field

[0001] The present invention relates to the technical field of fasteners, and more particularly to a shock-resistant conical wheel hub nut for automobiles. Background Art

[0002] Nuts are parts that tightly connect mechanical equipment. They are used in many industries: transportation, foundry, shipbuilding, wind power generation, etc. According to the different needs of different industries, nuts have different types, materials and standards. Among them, nuts are often used on high-speed vehicles such as car tires. Long-term high-speed movement and vibration of the vehicle body will cause the nuts on the tires to loosen and have poor fatigue resistance. Technical problems such as poor performance. This kind of failure in actual engineering can easily cause the machine to fail to work properly or even cause catastrophic accidents.

[0003] An existing high-strength anti-disassembly automobile nut, with the announcement number: CN 221054120 U, includes a nut body and a hexagonal sleeve block, the inner wall of the hexagonal sleeve block is rotatably connected to the nut body, and an anti-disassembly structure is provided on the left side of the hexagonal sleeve block, and the anti-disassembly structure includes a first spring, and the two ends of the first spring are respectively fixedly connected to the hexagonal sleeve block and the round block. By moving the T-block to the right, the T-bar drives the round block to move, and the round block drives the first spring to compress, and the hexagonal sleeve block is rotated to make the connecting rod correspond to the connecting groove, and then the T-bar is rotated, and the T-bar drives the cam to rotate, so that the connecting rods on both sides move, when the connecting rod and the connecting groove, the nut body rotates when the staff rotates the hexagonal sleeve block with the help of a wrench, and when the connecting rod and the connecting groove are disconnected, only the hexagonal sleeve block can be rotated alone. This kind of automobile nut has good fixation, but if it is set on the wheel hub under a vibration environment, it is easy to break under long-term vibration, affecting the safety of use.

[0004] An existing combined self-locking nut, with publication number: CN 219549314 U, comprises a nut body, a screw hole is arranged in the nut body, a sealing groove is opened at the bottom of the nut body, a sealing ring and a top ring are arranged in the sealing groove from the inside to the outside, and a slope is arranged on the side of the top ring contacting the sealing ring. This kind of nut presses the screw rod by the sealing ring to achieve anti-loosening and anti-vibration. The use of a strong rigidity method for anti-vibration will lead to direct transmission of vibration, causing fatigue and damage to the structure, and the vibration effect is limited, and it is impossible to effectively absorb and disperse the vibration.
