The invention provides an auxiliary wheel and a cart. The auxiliary wheel comprises a wheel set, an auxiliary wheel set and a power supply assembly. The wheel set comprises a wheel fork and a wheel rotating around the wheel fork. The auxiliary wheel set is connected to the wheel set and is in running fit with the wheels. The power supply assembly is electrically connected with the auxiliary wheel set. The auxiliary wheel set is additionally arranged on the wheel, the wheel structure is simplified, the weight of the wheel is reduced, the manufacturing cost is low, and maintenance is convenient. Meanwhile, after the power supply assembly is powered on, the auxiliary wheel sets assist the wheels to move forwards through friction force or driving force generated by rotation and the wheels, and the pushing force of the cart is reduced.
本申请提供一种辅助轮及推车。辅助轮包括车轮组、辅助车轮组和电源组件。车轮组包括轮叉和绕轮叉转动的车轮。辅助车轮组连接在车轮组上并与车轮转动配合。电源组件与辅助车轮组电连接。本申请在车轮上增加辅助车轮组,简化车轮结构,使车轮的重量减轻,制造成本低且方便维修。同时辅助车轮组在电源组件通电后,辅助车轮组通过转动与车轮产生的摩擦力或驱动力来辅助车轮前行,减小推车的推行力。
