The invention relates to an auxiliary wheel which comprises hubs including an outer hub and an inner hub and a tire arranged on the periphery of the outer hub in a surrounding manner; a through hole extending in the axial direction of the outer hub is formed in the center of the outer hub, the inner hub is inserted into the through hole, the outer hub and the inner hub are detachably connected through a first connecting assembly, and when the first connecting assembly relieves connection between the outer hub and the inner hub, relative rotation can be generated between the outer hub and the inner hub. The hub is designed into the outer hub and the inner hub in a split mode, when the connection state of the outer hub and the inner hub is released, relative rotation can be generated between the outer hub and the inner hub, in this way, rolling friction is generated between a tire and the ground in the trailer process, friction force is small, and abrasion to the tire is small.

    本发明涉及一种辅助车轮,包括轮毂,包括外轮毂以及内轮毂;轮胎,围设在外轮毂的外周;所述外轮毂的中央部位设有沿其轴向延伸的通孔,所述内轮毂插装在该通孔中,且外轮毂和内轮毂通过第一连接组件能拆卸地相连,在第一连接组件解除对外轮毂和内轮毂的连接时,所述外轮毂和内轮毂之间能产生相对转动。本发明通过将轮毂分体设计为外轮毂和内轮毂,在外轮毂和内轮毂的连接状态解除时,外轮毂和内轮毂之间能产生相对转动,这样在拖车时,轮胎和地面之间是滚动摩擦,摩擦力小,对轮胎的磨损小。
