Description

Technical Field

[0001] The utility model relates to the technical field of wheel spokes, in particular to a wheel spoke for a high-load-bearing truck. Background Art

[0002] In daily vehicle use, wheels are essential components for load-bearing and propulsion, and the reliability of their structure is directly related to vehicle safety and performance. This is especially true in adverse weather conditions, such as when driving through flooded roads. Moisture can form water stains on the bolts connecting the wheel spokes to the axle, which are often exposed to the elements.

[0003] This exposure makes the bolts vulnerable to intrusion by external debris, such as dirt, sand and other debris. These debris may not only adhere to the surface of the bolts, but may also cause corrosion or wear of the bolts, thereby affecting their load-bearing capacity and tightening effect. Once the bolts are damaged, the connection between the spokes and the axle may become loose or fail. In severe cases, the spokes may break or fall off, posing a great hidden danger to driving safety. Therefore, it is necessary to propose a high-load-bearing load-carrying vehicle wheel spoke to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a high-load-bearing truck wheel spoke.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A wheel spoke for a high-load-bearing truck comprises a spoke body, wherein the outer wall of the spoke body is provided with multiple groups of connecting parts, and screw holes are penetrated through the outer walls of the multiple groups of connecting parts. An adjustment groove is provided on one side of the connecting part between the spoke body and the connecting part, and a side plate is rotatably connected in the adjustment groove. A sleeve is fixedly connected to the outer wall of the side plate, and a sliding rod is slidably connected in the sleeve. The sliding rod is arranged through the side plate, and a sealing plug is fixedly connected to the end of the sliding rod, and the sealing plug fits inside the screw hole. An elastic component is installed in the sleeve to drive the sealing plug to stably fit in the screw hole.

[0007] Preferably, the elastic component includes a spring fixedly connected to the top of the sleeve, the other end of the spring is fixedly connected to a slider, and the slider is fixedly connected to the slide rod.

[0008] Preferably, the inner wall of the sleeve and the outer wall of the slider are both circular, and the outer wall of the slider is in close contact with the inner wall of the sleeve.

[0009] Preferably, a limiting ring is fixedly connected to the junction between the side plate and the slide rod, and the inner diameter of the limiting ring is smaller than the outer diameter of the slider.

[0010] Preferably, the outer wall of the side plate is trapezoidal, and the side wall of the sealing plug fits tightly against the inner wall of the screw hole.

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model can effectively prevent the entry of moisture, dirt and debris through the tight fit between the sealing plug and the screw hole, significantly reducing the risk of corrosion and wear of the bolts and connecting parts. The continuous restoring force provided by the spring ensures that the sealing plug always maintains close contact with the screw hole, which helps to keep the bolt clean, thereby extending its service life and avoiding safety hazards caused by corrosion or loosening.

[0013] 2. The rotatable side panel design of this utility model allows for more flexible opening and closing of the sealing plug within the screw hole. When removing or maintaining the bolt, the side panel can be easily rotated to remove the sealing plug without affecting the use of removal tools. This ensures sealing reliability and improves the convenience of bolt maintenance and replacement, effectively avoiding the inconvenience caused by obstruction of the sealing component.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-3When the cam 5 is in the engagement with the engagement member 2, the cam 5 is engaged with the engagement member 3 and the engagement member 4 is engaged with the engagement member 5. When the cam 5 is engaged with the engagement member 2, the engagement member 4 is engaged with the engagement member 3. When the cam 5 is engaged with the engagement member 2, the engagement member 4 is engaged with the engagement member 3.

[0020] The elastic component includes a spring 7 fixedly connected to the top of the sleeve 6, and the other end of the spring 7 is fixedly connected to a slider 8, which is fixedly connected to the slide rod 9. The inner wall of the sleeve 6 and the outer wall of the slider 8 are both circular, and the outer wall of the slider 8 is in close contact with the inner wall of the sleeve 6. A limiting ring 10 is fixedly connected to the junction of the side plate 5 and the slide rod 9. The inner diameter of the limiting ring 10 is smaller than the outer diameter of the slider 8. The outer wall of the side plate 5 is trapezoidal, and the side wall of the sealing plug 4 is in close contact with the inner wall of the screw hole 3; the spring 7 can provide the necessary restoring force between the slider 8 and the sleeve 6. When the slide rod 9 is subjected to external pressure or displacement during movement, the spring 7 will use its elastic characteristics to return the slider 8 to its initial position. This restoring force ensures that the sealing plug 4 can always maintain a close fit with the inner wall of the screw hole 3.

[0021] In the present invention, the device is specifically used as follows: the spoke body 1 is preliminarily connected to the axle, ensuring that the connecting part 2 is aligned with the screw hole 3, and the bolt is fixed to the connecting part 2 using appropriate tools to ensure that the tightness meets the vehicle specifications to avoid loosening.

[0022] Then push the sealing plug 4 inward, at this time the spring 7 is in a compressed state, then rotate the side plate 5, rotate the sealing plug 4 until it is in overlap with the screw hole 3, then release your hand, and under the action of the spring 7 to restore, drive the sealing plug 4 to slide into the screw hole 3, and the sealing plug 4 is tightly fitted with the inner wall of the screw hole 3. At this time, the edge of the sealing plug 4 forms an effective seal to prevent moisture, dirt and other debris from entering the interior of the spoke, thereby protecting the integrity of the connecting parts.

[0023] When the vehicle passes over an uneven road or carries a heavy load, the spring 7 can still provide a continuous restoring force to ensure close contact between the sealing plug 4 and the screw hole 3, further enhancing the safety of the wheel spoke.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
