The invention provides a corrosion-resistant electro-tricycle hub with a good protection effect, and relates to the technical field of electro-tricycle hubs, the corrosion-resistant electro-tricycle hub with the good protection effect comprises an inner rim, a connecting piece is welded to the outer wall of the inner rim, and the end, away from the inner rim, of the connecting piece is connected with an outer rim; a protection expansion pipe is arranged on the outer side of the connecting piece and is in a spiral shape, the end, located on the outer side, of the protection expansion pipe is connected with an air inlet cover, a fixing cylinder is fixed to the outer wall of the protection expansion pipe, and a connecting arc rod is installed on the outer wall of the fixing cylinder. According to the corrosion-resistant electro-tricycle hub with the good protection effect, the spiral protective expansion pipe is driven to rotate when the hub rotates, the spiral protective expansion pipe can rotate on the side portion of the hub to face the hub to protect the hub, the situation that the hub is abraded due to the fact that stones collide with the hub in the driving process is avoided, meanwhile, the air inlet cover can guide air flow into the protective expansion pipe in the rotating process, the protective expansion pipe is expanded, and the protective effect is improved.
本发明提供一种防护效果好的耐腐蚀电动三轮车轮毂,涉及电动三轮车轮毂技术领域,该防护效果好的耐腐蚀电动三轮车轮毂,包括内轮圈,所述内轮圈的外壁焊接有连接件,且连接件远离内轮圈的一端连接有外轮圈,所述连接件的外侧设有防护膨胀管,且防护膨胀管呈螺旋状,所述防护膨胀管位于外侧的一端连接有进风罩,所述防护膨胀管的外壁固定有固定筒,所述固定筒的外壁安装有连接弧杆,该防护效果好的耐腐蚀电动三轮车轮毂,通过轮毂旋转时带动螺旋状的防护膨胀管旋转,可在轮毂侧部旋转成面对轮毂进行防护,避免行驶过程中石子碰撞在轮毂处对其造成磨损,同时旋转过程中进风罩可将气流导至防护膨胀管内,使其膨胀,提高防护效果。
