Description

Technical Field

[0001] The utility model relates to the technical field of heavy truck axle accessories, in particular to a heavy truck axle spacer ring which is wear-resistant and has a long service life. Background Art

[0002] Heavy truck axles are an important part of heavy trucks. Gaskets are needed at the bolted joints of axle components to prevent leakage due to pressure, corrosion, and natural thermal expansion and contraction of pipes.

[0003] At present, the existing gasket body, fixing groove, metal washer, pin hole, groove and anti-wear washer are set. When in use, the set metal washer can improve the structural strength of the contact between the gasket body and other components, and the anti-wear washer can improve the wear resistance of the pin hole of the gasket body, thereby avoiding the pin hole of the gasket body from wearing too fast and causing the sealing effect of the gasket body to fail. The metal washer and the anti-wear washer cooperate with each other to improve the overall wear resistance of the axle gasket, reduce the wear rate of the axle gasket, and thus increase the service life of the axle gasket.

[0004] For example, the long-life heavy-duty truck axle gasket disclosed in authorization announcement number CN214304814U includes a gasket body, the upper and lower sidewalls of the gasket body are each provided with a fixing groove, both of the fixing grooves are connected to the inner hole of the gasket body, both of the fixing grooves are fixedly connected to a metal washer, and the metal washer does not extend out of the fixing groove, the upper sidewall of the gasket body is evenly provided with eight pin holes, the upper and lower sidewalls of the gasket body are each provided with eight grooves corresponding to the pin holes, and anti-wear washers are fixedly connected to the grooves, and the anti-wear washers are flush with the gasket body. However, the rectangular block and slot design of such a long-life heavy-duty truck axle gasket easily causes the metal washer to slip, and the gasket body is easily loosened when the heavy-duty truck axle moves and vibrates.

[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that the design of the rectangular block and the slot can easily cause the metal gasket to slip, and the gasket body can easily loosen when the heavy truck bridge moves and vibrates. Therefore, the existing technology needs to be improved. Utility Model Content
