Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
embodiment 1
see the pushchair shown in Fig. 1, Fig. 2, comprise wheel hub 2 and be set in the tire 1 outside wheel hub 2 in perimembranous regularly.
shown in Fig. 2, Fig. 3, tire 1 is a kind of tyre without charging, this tire 1 offers the hollow vallecular cavity 11 with notch 13 along the circumference of tire 1, notch 13 is positioned in the inner side perimembranous of tire 1, the inner side perimembranous of tire 1 split by notch 13, the both sides making the inner side perimembranous of tire 1 be positioned at notch 13 form the support portion 14 of ring-type respectively, tire 1 can be sheathed with in the outside perimembranous of wheel hub 2 regularly by annular support part 14.Owing to being provided with hollow vallecular cavity 11, effectively can improve the elasticity of tire 1, make wheel entirety have good damping effect.
in the present embodiment, shown in Fig. 2,3, tire 1 upper annular support portion 14 also offers opening towards the annular recess inside tire 1, multiple reinforced rib 15 along the circumferential direction spaced apart is provided with in this annular recess, reinforced rib 15 extends along the radial direction of tire 1 in above-mentioned annular recess, when tire 1 sheathed on the hub 2 time, reinforced rib 15 is supported in the outside perimembranous of wheel hub 2.Adopt above-mentioned setting, the integral, flexible of tire 1 can be made to be improved further, make wheel entirety have better shock-proof effect.
shown in Fig. 2, Fig. 3, this tire 1 is arranged in hollow groove chamber 11 and is also fixedly provided with annular reinforcer 3, the number of this annular reinforcer 3 can be one, also can be multiple.The axial line of the annular reinforcer 3 and axial line of tire 1 should be parallel to each other or conllinear extends.
annular reinforcer 3 is in hollow vallecular cavity 11, outside it, perimembranous is conflicted regularly on the circumferential cell wall that hollow vallecular cavity 11 is positioned at tire 1 radially outer, when wheel pressurized, this annular reinforcer 3 is formed the circumferential cell wall in hollow groove chamber 11 to support, thus make tire 1 keep suitable elastomeric while, its entirety also has good rigidity, and then tire 1 is not easily deformed.
annular reinforcer 3 should adopt to be had certain rigidity and has suitable elastomeric material concurrently and make, thus does not affect the integral, flexible of tire 1 while the rigidity improving tire 1, ensures that wheel has good shock-absorbing performance.The becket that this annular reinforcer 3 can adopt metallic material to make, as iron wire ring, or the steel loop that elastic steel sheet is made.Can certainly adopt and have certain rigidity concurrently and elastomeric plastic item is made.
