accompanying drawing 2 is along A-A in Fig. 1 to cross-sectional schematic;
accompanying drawing 3 is B portion enlarged diagram in accompanying drawing 2;
wherein: 1, tire; 11, hollow vallecular cavity; 12, notch; 13, annular support part; 14, reinforced rib; 3, elastic reinforcement member.
Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
see the pushchair shown in Fig. 1, Fig. 2, comprise wheel hub 2 and fixed cover and be located at tire 1 outside wheel hub 2 in perimembranous, wherein tire 1 is non-inflatable tyre, this tire 1 offers the hollow vallecular cavity 11 with notch 12 along the circumferencial direction of tire 1, in the inner side perimembranous that this notch 12 is positioned at tire 1 and towards wheel hub 2.The inner side perimembranous of tire 1 split by notch 12, the two side portions making the inner side perimembranous of tire 1 be positioned at notch 12 respectively forms an annular support part 13, tire 1 can be set in the outside perimembranous of wheel hub 2 regularly by annular support part 13.Due to tire 1 having hollow vallecular cavity 11, effectively can improve the elasticity of tire 1 like this, make wheel entirety have good damping effect.
in the present embodiment, shown in Fig. 2, Fig. 3, the annular support part 13 of tire 1 also offers annular recess, the opening of this annular recess is towards the radially inner side of tire 1.Be provided with multiple reinforced rib 14 along the circumferential direction spaced apart in above-mentioned annular recess, reinforced rib 14 extends along the radial direction of tire 1 in above-mentioned annular recess, when tire 1 sheathed on the hub 2 time, reinforced rib 14 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 pushchair also comprises at least one elastic reinforcement member 3 banded ringwise, this elastic reinforcement member 3 is located in the hollow vallecular cavity 11 of tire 1, and the circumferential cell wall being positioned at tire 1 radial outside in this elastic reinforcement member 3 and hollow vallecular cavity 11 fixes interlocking, thus fixing resilient mounting can be formed to part tire 1 being positioned at hollow groove chamber 11 radial outside.Because elastic reinforcement member 3 is banded ringwise, between itself and the circumferential cell wall of hollow vallecular cavity 11, there is larger area of contact, and again because this elastic reinforcement member 3 is fixed together with tire 1, therefore there is good load performance, the part that can be formed tire 1 being positioned at hollow groove chamber 11 radial outside gives good and stable support, when wheel is subject to larger pressure, the phenomenon that this elastic reinforcement member 3 also not easily occurs fracture or is separated with tire 1.Adopt above-mentioned setting, can make tire 1 keep suitable elastomeric while, its entirety also can have good rigidity, and tire 1 is not easily deformed.
shown in Fig. 2, Fig. 3, this elastic reinforcement member 3 should adopt to be had certain rigidity and has suitable elastomeric material concurrently and make, thus while the rigidity improving tire 1, do not affect the integral, flexible of tire 1, ensure that wheel has good shock-absorbing performance, its metallic elastic ring can made for metallic material, the plastic resilient ring also can made for plastic material.The number of elastic reinforcement member 3 can be one in the present embodiment, also can be multiple, the axial line of the axial line of elastic reinforcement member 3 and tire 1 can be made to be parallel to each other or conllinear extends when arranging.
elastic reinforcement member 3, in hollow vallecular cavity 11, can adopt the following two kinds set-up mode:
a kind of is be embedded regularly by elastic reinforcement member 3 be arranged in the circumferential cell wall of tire 1 radial outside at hollow vallecular cavity 11 and make elastic reinforcement member 3 and tire 1 form one, can be inserted in the injection mould of forming tire 1 by elastic reinforcement member 3 before tire 1 injection moulding production and processing.Like this, elastic reinforcement member 3 and tire 1 are fixed all the time, ensure tire 1 have suitable elastomeric while effectively improve its integral rigidity.According to this kind of set-up mode, elastic reinforcement member 3 should meet on-deformable material in tire 1 injection molding and be made, as adopted metallic elastic ring, or the plastic resilient ring different from tire 1 material.
another kind is then after tire 1 injection moulding completes, and to be inserted by elastic reinforcement member 3 in hollow vallecular cavity 11 and be fixed to be connected on the circumferential cell wall of hollow vallecular cavity 11.When arranging, can in the circumferential cell wall of tire 1 radial outside and the salient and the fitting portion (not shown) that arrange corresponding cooperation between elastic reinforcement member 3 on hollow vallecular cavity 11, then above-mentioned salient correspondence is snapped in fitting portion, fixing between elastic reinforcement member 3 and tire 1 can be realized, thus formed stable support tire 1 being positioned at hollow groove chamber 11 radial outside portion.Under this kind of set-up mode, elastic reinforcement member 3 both can adopt metallic elastic ring, also can adopt plastic resilient ring.
to sum up, pushchair of the present utility model, wherein by arranging elastic reinforcement member 3 banded ringwise in the hollow vallecular cavity 11 of tire 1, the circumferential cell wall being positioned at tire 1 radial outside in elastic reinforcement member 3 and hollow vallecular cavity 11 is made to fix interlocking, thus formed tire 1 being positioned at the part of hollow groove chamber 11 radial outside with fixing resilient mounting, make tire 1 suitably elastomericly also have good rigidity in maintenance simultaneously, and then make wheel entirety have good shock-absorbing and comfort.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
