Technical Field
[0001] This utility model belongs to the field of automotive wheel hub technology, specifically a high-strength anti-vibration toothed strip for heavy-duty vehicle wheel hubs. Background Technology
[0002] Some heavy-duty truck wheel hubs lack effective shock-absorbing structures when subjected to heavy loads and complex road conditions over long periods, relying solely on threaded fastening. These wheel hubs are prone to loosening due to continuous vibration, posing a safety hazard. After installation, these wheel hubs are generally directly exposed to the outside environment. In rainy weather, it is difficult to prevent rainwater and corrosive media from seeping into the threads, accelerating thread corrosion. Without proper treatment over a long period, the wheel hubs will rust under the oxidation of external oxygen, creating a safety hazard. Therefore, improvements are needed to address this issue. Utility Model Content
[0003] In response to the above situation and to overcome the shortcomings of existing technologies, this utility model provides a high-strength anti-vibration threaded rod for heavy-duty truck wheel hubs. This effectively solves the problem that some heavy-duty truck wheel hub threaded rods lack an effective anti-vibration structure when subjected to long-term heavy loads and complex road conditions, relying solely on thread fastening. In such cases, the threaded rod is prone to loosening due to continuous vibration, leading to safety hazards. Furthermore, after being fixed, these threaded rods are generally directly exposed to the outside environment. During rainy weather, it is difficult to prevent rainwater and corrosive media from seeping into the threads, accelerating thread corrosion. If left untreated for a long time, the threaded rod fixing the truck wheel hub will rust under the oxidation of external oxygen, creating a safety hazard.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-strength anti-vibration toothed rod for heavy-duty truck wheel hubs, comprising a toothed rod and a protective ring, wherein the protective ring is located on the outside of the toothed rod, an anti-vibration component is provided on the outside of the toothed rod, and a protective component is provided at the top of the toothed rod;
[0005] The shock-absorbing component includes a first pad, which is disposed on the outside of the toothed bar. A second pad is disposed on the outer wall of the toothed bar, which is located below the first pad. The first pad and the second pad are provided with toothed surfaces on opposite sides and interlock with each other. One side of the first pad and the second pad is provided with a serrated surface.
[0006] Preferably, the top of the toothed bar is hexagonal, and the top of the toothed bar is provided with a groove.
[0007] Preferably, the protection component includes a connecting ring connected inside the protection ring, and a connecting groove is provided at the bottom of the top of the toothed bar, with the connecting ring located inside the connecting groove.
[0008] Preferably, a limiting ring is connected to the top of the connecting ring, and the limiting ring is located inside the connecting groove.
[0009] Preferably, the outer wall of the toothed bar is connected to a first sealing ring, which fully covers the outer wall of the top of the toothed bar.
[0010] Preferably, a second sealing ring is connected to the bottom of the protective ring.
[0011] Preferably, the protective ring has a protective groove inside, which matches the top of the toothed bar.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The shock-absorbing component buffers vibration through the interlocking first and second pads. The teeth of the pads are tightly interlocked to form a stable friction contact surface to disperse the impact force. The serrated surface enhances friction damping to prevent loosening, thereby improving the shock resistance and structural stability, and ensuring the reliable operation of the wheel hub under heavy load and vibration conditions.
[0014] 2. The protective component is precisely fitted with the protective ring at the top of the toothed bar to form a sealed protective structure. The protective ring completely wraps around the top of the toothed bar, forming a waterproof barrier that effectively blocks the penetration path of rainwater along the toothed bar axis. This allows splashed rainwater to slide off along the outer wall of the protective ring. This design ensures that in heavy rain, rainwater is physically blocked from entering the internal threads and gasket engagement area of the toothed bar, fundamentally preventing rust and electrolytic corrosion of the threaded pair.
[0015] 3. The protective ring has a protective groove inside, which matches the top of the toothed bar, so that the protective groove and the toothed bar form a nested protective space, so that the top of the toothed bar is completely wrapped inside the protective ring, completely blocking the direct impact of rainwater and sand from the top.

Detailed Implementation
[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 A high-strength anti-vibration toothed rod for heavy-duty truck wheel hubs includes a toothed rod 100 and a protective ring 300. The protective ring 300 is located on the outside of the toothed rod 100. An anti-vibration component is provided on the outside of the toothed rod 100, and a protective component is provided on the top of the toothed rod 100.
[0025] The shock-absorbing component includes a first washer 200, which is sleeved on the outside of a toothed bar 100. A second washer 201 is sleeved on the outer wall of the toothed bar 100, located below the first washer 200. Both the first washer 200 and the second washer 201 have toothed surfaces 202 on opposite sides that mesh with each other. Both the first washer 200 and the second washer 201 have serrated surfaces 203 on one side. When the wheel hub of a heavy-duty truck is subjected to vibration or impact, the shock-absorbing component, through the first washer 200 and... The interlocking action of the second shim 201 is used to buffer vibration. The opposite sides of the first shim 200 and the second shim 201 are provided with toothed surfaces 202. The two are tightly interlocked to form a stable frictional contact surface, which can effectively disperse the impact force when subjected to external force. At the same time, the serrated surfaces 203 of the first shim 200 and the second shim 201 further increase the frictional damping, prevent loosening and enhance the anti-vibration performance, further improve the durability and stability of the overall structure, and ensure that the wheel hub can still maintain stable operation under heavy load and vibration environment.
[0026] The top of the toothed bar 100 is hexagonal, and a groove 204 is provided on the top of the toothed bar 100 to facilitate the rotation of the toothed bar 100 by the operator.
[0027] The protective component includes a connecting ring 301, which is fixedly connected to the inside of the protective ring 300. A connecting groove 302 is provided at the bottom of the top of the toothed bar 100, and the connecting ring 301 is located inside the connecting groove 302. The protective component is precisely fitted with the top of the toothed bar 100 and the protective ring 300 to form a sealed protective structure. The protective ring 300 completely wraps around the top of the toothed bar 100, forming a waterproof barrier that effectively blocks the penetration path of rainwater along the axial direction of the toothed bar 100, allowing splashed rainwater to slide off along the outer wall of the protective ring 300. This design ensures that in heavy rain, rainwater is physically blocked from entering the internal threads and gasket engagement area of the toothed bar 100, fundamentally preventing rust and electrolytic corrosion of the threaded pair.
[0028] A limiting ring 303 is fixedly connected to the top of the connecting ring 301. The limiting ring 303 is located inside the connecting groove 302, thereby preventing the protective ring 300 from detaching from the outside of the toothed rack 100.
[0029] A first sealing ring 304 is fixedly connected to the outer wall of the toothed rod 100. The first sealing ring 304 fully covers the outer wall of the top of the toothed rod 100, thereby physically isolating external rainwater, mud and other pollutants from directly contacting the threaded part of the toothed rod 100, preventing corrosive media from penetrating and causing thread corrosion. The compression and rebound characteristics of the first sealing ring 304 compensate for the assembly gap, and the sealing surface remains tightly fitted when the vehicle vibrates.
[0030] The bottom of the protective ring 300 is fixedly connected to a second sealing ring 305, which absorbs axial vibration caused by vehicle bumps through elastic deformation, avoids sealing failure caused by rigid contact, and maintains waterproof reliability for a long time.
[0031] The protective ring 300 has a protective groove 306 inside, which matches the top of the toothed bar 100, so that the protective groove 306 and the toothed bar 100 form a nested protective space, so that the top of the toothed bar 100 is completely wrapped inside the protective ring 300, and the direct impact of rainwater and sand is completely blocked from the top.
[0032] Working principle: When the wheel hub of a heavy-duty truck is subjected to vibration or impact, the shock-absorbing component buffers the vibration through the interlocking of the first washer 200 and the second washer 201. The opposite sides of the first washer 200 and the second washer 201 have toothed surfaces 202, which interlock tightly to form a stable frictional contact surface. This effectively disperses the impact force when subjected to external forces. Simultaneously, the serrated surfaces 203 of the first washer 200 and the second washer 201 further increase frictional damping, prevent loosening, and enhance shock resistance, further improving the durability and stability of the overall structure. This ensures that the wheel hub can maintain stable operation under heavy loads and vibrations. The protective component precisely engages with the protective ring 300 through the top of the toothed rack 100, forming a tight... The protective structure, with the protective ring 300 completely enclosing the top of the toothed strip 100, forms a waterproof barrier, effectively blocking the penetration path of rainwater along the axial direction of the toothed strip 100. This allows splashed rainwater to slide off the outer wall of the protective ring 300. This design ensures that in heavy rain, rainwater is physically blocked from entering the internal threads and gasket engagement area of the toothed strip 100, fundamentally preventing rust and electrolytic corrosion of the threaded pair. The protective ring 300 has a protective groove 306 inside, which matches the top of the toothed strip 100, forming a nested protective space. This completely encloses the top of the toothed strip 100 inside the protective ring 300, effectively blocking the direct impact of rainwater and sand from the top.
