The utility model is described in further detail below in conjunction with drawings and Examples.
A kind of universal travel wheel as shown in Figures 1 and 2, the road wheel 2 include main axle 21, it is vertical and be rotatablely installed in
The rolling wheel support 22 of main axle 21 and the auxiliary wheel 23 being rotatably installed on rolling wheel support 22, rolling wheel support 22 include it is adjacent simultaneously
Two groups to be staggered, it is preferable that rolling wheel support 22 includes the multiple supporting parts 221 and wheel shaft equal with the quantity of auxiliary wheel 23
Portion 222, wheel axle portion 222 both ends are rotatably connected on the one end of supporting part 221, and the other end of supporting part 221 is fixed with main axle 21 to be connected
Connect.The length of all supporting parts 221 is identical, and similar isosceles triangle is formed with wheel axle portion 222.Auxiliary wheel 23 is spindle knot
Structure, the quantity of unilateral auxiliary wheel 23 are 3~6, preferably 4, two groups of auxiliary wheels totally 8 spindle rollers.It is unilateral auxiliary
Help roller 23 be 4 when, two groups of rolling wheel supports 22 are arranged side by side, around main axle 21 interlock 45 °, rolling wheel support as shown in Figure 3
22 staggeredly mode, reduces the gap between two staggeredly adjacent rollers, it is ensured that each angle in the rolling process of road wheel 2 as far as possible
Degree has auxiliary wheel 23 to land as far as possible, ensures to roll and turns to smooth.Similarly, when unilateral auxiliary wheel 23 is 3, two groups simultaneously
The rolling wheel support 22 set is arranged around main axle 21 to interlock 60 °
When unilateral auxiliary wheel 23 is 4, a side roller brackets 22 have 4 supporting parts 221, each supporting part 221 with
