Abstract: A wheel set includes a primary wheel and two secondary wheels. The secondary wheels are disposed at two sides of the primary wheel, respectively. The primary wheel is provided with non-circular engaging members at the two sides. Each secondary wheel is provided with a corresponding engaging member to be engaged with the primary wheel. Molds for the primary wheel and the secondary wheels can be separately developed so as to reduce the total production cost. When taking a turn, the primary wheel and the secondary wheels are operated together to achieve a smooth turn.

Abstract: A coaxial structure of auxiliary wheels and a primary wheel includes a frame, an axle, a primary wheel and two auxiliary wheels. The frame is pivotally connected to the axle. Both the primary wheel and the auxiliary wheels are separately inserted with bearings or sleeves. The bearings or the sleeves are further inserted onto the axle. Both the primary and the auxiliary wheels wear tires made of different material to increase the contact area with the ground while the frame is inclined to take a turn to prevent from turning over.
