The invention discloses a vacuum heat insulation truck and passenger car rim and a machining method and application thereof.The rim comprises a rim, a bead seat, a groove bottom, a vacuum layer, a spoke and a vacuum layer outer armor, and the vacuum layer is arranged at the position, located on the lower portion of the bead seat and the groove bottom, of the rim; the vacuum layer is of an internal vacuum structure formed by tightly combining a vacuum layer outer armor and a rim through a vacuum welding technology. The invention can be applied to a multi-piece rim wheel with an inner tube, and can also be applied to a one-piece rim wheel without an inner tube. During machining, the two faces of the vacuum layer outer armor are firstly machined, the embedded teeth of the face B are provided with embedded tooth guide structures, the face A and the face B are embedded together and welded in a vacuum mode, and finally the spoke is welded to the vacuum layer outer armor. According to the invention, the conduction of high temperature to the rim bead seat, the groove bottom and the bead can be reduced, and the problems of rubber aging and tire burst caused by long-term high temperature of the bead are reduced.

    本发明公开了一种真空隔热的卡客车轮辋及其加工方法和应用,所述轮辋包含轮缘、胎圈座、槽底、真空层、轮辐和真空层外装甲,在轮缘处、位于胎圈座和槽底下部设置有真空层,所述真空层为由真空层外装甲与轮辋通过真空焊接技术紧密结合形成的内部真空结构。本发明可用于有内胎的多件式轮辋的车轮,也可应用到无内胎的一件式轮辋的车轮。加工时,先加工真空层外装甲的两个面,B面的嵌合齿设计有嵌合齿导向结构,A、B两个面嵌合在一起,真空焊接,最后将轮辐与真空层外装甲焊接。本发明可降低高温向轮辋胎圈座、槽底、胎圈的传导,减少因胎圈长期高温造成的橡胶老化爆胎问题。
