As improvement, described ball and retainer are two groups, are arranged between wheel body and rotating shaft spacing side by side.
As improvement, one end of described wheel body is provided with ring-shaped step, and the sidewall of described ring-shaped step is slope.
As improvement, the two ends of described rotating shaft are fixed on the concrete structure be arranged on the support of vehicle bottom and are: the two ends of described rotating shaft are provided with annular groove, and described rotating shaft is placed on support, and the two ends of rotating shaft are stretched out outside support, and are fixed on support with snap ring.
As improvement, the two ends of described rotating shaft, are respectively arranged with cover of dust between wheel body and rotating shaft.
As improvement, the outside of described cover of dust is respectively arranged with rubber seal ring, described rubber seal ring is fixed on the two ends of wheel body respectively with annular baffle ring, described rotating shaft is successively through rubber seal ring and annular baffle ring, the inwall of described rubber seal ring contacts with the surface of rotating shaft, and gap is left on the described inwall of annular baffle ring and the surface of rotating shaft.
As improvement, the two ends of described wheel body are provided with several screw, and described annular baffle ring is fixed on wheel body by screw.
As improvement, the quantity of described screw is preferably at least 3, and concrete pressing is designed and determine.
As improvement, the outside face of described wheel body scribbles polytetrafluorethylecoatings coatings.
Compared with prior art, the present invention adopts between described wheel body and rotating shaft and is provided with ball, the inwall of described wheel body is provided with inner ring groove, the correspondence position of described rotating shaft is provided with outer annular groove, described ball can rollably be placed on retainer, and can be placed between wheel body and rotating shaft actively together with retainer, the outside face of described ball contacts with the surface of inner ring groove and outer annular groove, and the two ends of described rotating shaft are fixed on and are arranged on the support of vehicle bottom.The invention has the advantages that: using wheel body directly as the outer ring of bearing, and rotating shaft is directly as the inner ring of bearing, the structure of wheel can be made so compacter, and be provided with double-row balls between wheel body and rotating shaft, the operation of wheel can be made more steady, again because be provided with cover of dust and rubber seal ring respectively at the two ends of rotating shaft, not only can prevent grease from leaking outside but also can prevent impurity from entering in wheel, thus effectively extend the service life of wheel, also have, polytetrafluorethylecoatings coatings is scribbled at the outside face of wheel body, thus can better play antirust, wear-resisting and anti-creeping effect, then the quality of product is further increased.
