Abstract
The utility model discloses a kind of combined tire, it comprises cover tire and fuse.Described cover tire is an annular element, and it has one around all-round core groove; Described fuse is an annular element, and its mode with interference fit is nested with in the core groove of cover tire, between cover tire core groove inwall and fuse, has gap.Because the utility model is mainly made up of cover tire and fuse, fuse is nested with in the core groove of cover tire, cover tire inner chamber can be propped up, therefore it is larger that the core channel opening of cover tire can be opened, in production process of the present utility model, can be easier to take out for the core rod of moulding cover tire core groove, production efficiency is higher.Again, because the utility model is made up of cover tire and fuse two parts, between cover tire core groove inwall and fuse, there is gap, this gap size can regulate as required, there is good buffer action, and cover tire of the present utility model can adopt with fuse the material that hardness is different, traveling comfort is better.
Description
Technical field
The utility model relates to a kind of tire, particularly relates to a kind of combined tire.
Background technology
Solid tyre is generally made up of rubber and expanded material, even at uneven road surface, the situation such as also can not blow out, is used safer.But because solid tyre deflection is little, in the time running into the protrusions such as stone in driving process, application force is directly passed to wheel hub by solid tyre, makes driver's traveling comfort poor.Chinese patent CN201010107905.0 discloses a kind of method for making (as shown in Figure 1) of hollow solid tire, comprises the steps: multiple modules to combine core rod 2 ', and this core rod 2 ' is fixed in tire forming mold 1 '; Mold 11 ' is snapped onto to bed die 12 ' upper, inject foaming material liquid from plug hole 13 ', make foaming material liquid be full of the space between mould 1 ' inwall and core rod 2 ' and solidify; Then tire 10 ' and core rod 2 ' are taken out in mould 1 ', mould 1 ' is disassembled and taken out one by one module, thereby form hollow solid tire.This kind of method, in the moulding by casting process of solid tyre, utilizes removable core rod 2 ' be combined with foaming material and form hollow space, and then takes out one by one after core rod 2 ' is disassembled.Tire 10 ' the lumen openings of this method for making after due to moulding is less, and core rod 2 ' is had to very large enclasping force, and dismounting core rod 2 ' is very difficult, and production efficiency is low.And this tire 10 ' of commonly using structure is from middle opening, water and foreign matter are easily entered in actual use.In addition, the screen resilience on the tire 10 ' ground of this structure directly acts on wheel hub by tire 10 ', and traveling comfort is poor.And the hollow solid tire of this structure, easily easily runs in tire because the existence of opening causes the foreign matters such as stone.
Utility model content
The purpose of this utility model be to provide a kind of traveling comfort good, assemble easy combined tire.
For achieving the above object, technical solution of the present utility model is:
Utility model is a kind of combined tire, and it comprises cover tire and fuse; Described cover tire is an annular element, and it has one around all-round core groove; Described fuse is an annular element, and its mode with interference fit is nested with in the core groove of cover tire, between cover tire core groove inwall and fuse, has gap.
Described cover tire core groove notch both sides extend internally respectively, form convex edge; The cross-sectional plane of described fuse is stepped, and the cascaded surface of fuse is connected on the convex edge of cover tire core groove notch.
On the annular outer wall of described fuse, there is one around all-round arc deep gouge.
Adopt after such scheme, the utlity model has following advantage:
1, because the utility model is mainly made up of cover tire and fuse, fuse is nested with in the core groove of cover tire, cover tire inner chamber can be propped up, therefore, it is larger that the core channel opening of cover tire can be opened, in production process of the present utility model, can be easier to take out for the core rod of moulding cover tire core groove, production efficiency is higher.
2, because the utility model is made up of cover tire and fuse two parts, between cover tire core groove inwall and fuse, there is gap, this gap size can regulate as required, there is good buffer action, and cover tire of the present utility model can adopt with fuse the material that hardness is different, traveling comfort is better.
3, owing to being connected together by cascaded surface between the utility model cover tire and fuse, clamping is firm, can not come off.
4, because the utility model is by cover tire and fuse combined tire dimerous, completely cut off tyre cavity and the extraneous chance contacting, water and foreign matter are not easy to enter tyre cavity.
5, the utility model can be made gauge member by fuse, and PU cover tire has multiple unlike material, decorative pattern, model, and different PU cover tires and the assembling of the fuse of standard form multiple different tire.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Brief description of the drawings
Fig. 1 is the diagram of circuit of commonly using the method for making of hollow solid tire;
Fig. 2 is axonometric drawing of the present utility model;
Fig. 3 is front view of the present utility model;
Fig. 4 is the cutaway view of Fig. 3 along A-A line.
Detailed description of the invention
As shown in Fig. 2-Fig. 4, the utility model is a kind of combined tire, and it comprises cover tire 1 and fuse 2.
Described cover tire 1 is an annular element, and it has one around all-round core groove 11; Cover tire core groove 11 notch both sides extend internally respectively, form convex edge 12, and this convex edge 12 forms the tire lip of tire.
Described fuse 2 is an annular element, the cross-sectional plane of fuse 2 is stepped, when fuse 2 is nested with core groove 11 at cover tire 1 when interior in the mode of interference fit, between cover tire 1 core groove 11 inwalls and fuse 2, form gap 13, the cascaded surface 21 of fuse 2 is connected on the convex edge 12 of cover tire 1 core groove 11 notches, forms the inwardly power that an is locked F for compressing convex edge 12.In the time that tire is contained on wheel hub, this power F that is locked can, by tight the tire lockjaw of tire being socketed on wheel hub, can not come off tire, effectively prevented the cover tire backward outer expansion of 1 pressurized and with the generation of fuse 2 break-offs.
On the annular outer wall of described fuse 2, there is one around all-round arc deep gouge 22, the degree of depth of this arc deep gouge 22 can be determined according to forming gap 13 sizes between cover tire 1 core groove 11 inwalls and fuse 2, and in the time that gap 13 is larger, the hardness of tire is just lower, otherwise the hardness of tire is just higher.
Emphasis of the present utility model is just: tire has cover tire and fuse to be socketed to form.
The above, it is only the utility model preferred embodiment, thickness, the lines of cover tire can be determined according to needs, therefore can not limit the scope that the utility model is implemented with this, the equivalence done according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
