Form unsteady mode through first floating bead between spoke and the wheel body, can cushion the effort that self produced to the wheel body when the wheel body rotates, make the spoke produce reciprocal floating dynamic experience moreover and feel.
The method is further optimized as follows: the rotary ball is connected with the first floating ball in a floating way.
Adopt above-mentioned technical scheme, can cushion the effort that self produced to the wheel body.
The method is further optimized as follows: the spokes may also be curved.
By adopting the technical scheme, the spoke with the cambered surface can bear stronger centripetal force, so that the wheel body bears larger load, and the applicability is strong.
The method is further optimized as follows: the rotary ball is a hollow ball.
By adopting the technical scheme, the hollow ball is light, the used materials are less, and the manufacturing cost is low.
The method is further optimized as follows: one end of the spoke is fixedly connected with the inner wall of the rotary ball.
By adopting the technical scheme, the spoke is directly integrated with the rotary ball, and the bearing capacity is stronger.
The method is further optimized as follows: the rotary ball can also be a solid ball.
By adopting the technical scheme, the solid ball has stronger stability.
The method is further optimized as follows: one end of the spoke is fixedly connected with the geometric center of the rotary ball.
By adopting the technical scheme, the spoke and the rotary ball can be firmly connected together to bear stronger force.
The method is further optimized as follows: the spoke is made of aluminum alloy.
By adopting the technical scheme, the spoke made of the aluminum alloy material is light in weight and convenient to carry.
The method is further optimized as follows: the central disk is made of stainless steel.
By adopting the technical scheme, the novel outdoor sports shoes are not easy to rust, can be used for outdoor sports for a long time, and are attractive.
The method is further optimized as follows: the surface of the wheel body is subjected to antiseptic treatment.
By adopting the technical scheme, the sports entertainment can be carried out even on rainy days or ponding roads, and better experience is brought to users.
