Specific embodiment
It is practical to this below in conjunction with attached drawing in order to keep the purpose of this utility model, technical solution and advantage clearer
It is novel to be described in further detail, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work
Under the premise of all other embodiment obtained, fall within the protection scope of the utility model.
It is described in detail below in conjunction with a kind of novel PU wheel of Fig. 1 ~ Fig. 2 to the utility model embodiment.
With reference to shown in Fig. 1, Fig. 2, a kind of novel PU wheel provided by the embodiment of the utility model includes spoke 1, is fixed on
PU circle 2 and axle sleeve 3 on spoke 1, wherein spoke 1 includes spoke circle mouth 101, axle sleeve 3, connection spoke circle mouth 101 and axle sleeve 3
Spoke 102, be provided with fabrication hole 301 and bearing hole 302 on axle sleeve 3, spoke 102 tilts 15 ° ~ 45 ° fixations in the same direction
Between spoke circle mouth 101 and axle sleeve 3, PU circle 2 with a thickness of 15mm ~ 20mm.PU circle with a thickness of 15mm ~ 20mm, relatively
There is traditional PU wheel (the PU circle minimum 40mm of thickness) of technology to greatly reduce PU circle thickness, improves the thermal diffusivity of PU circle
Can, it is not only not in heartburn phenomenon, but also speed tradition PU wheel relatively can promote 30%, load-carrying can be improved 20%, make
It can be improved 2 times with the service life.
Referring to fig. 1 and fig. 2, specifically, the spoke 1 that the utility model embodiment uses is an integral structure, the wheel
Spoke 1 is engineering plastics spoke, and spoke 102 is tilted to same direction and the center symmetric setting about spoke circle mouth 101,
