Abstract
The invention provides a non pneumatic tire including a tire face part connecting with ground; an annular belt part supporting the tire face part; a wheel part departing from the annular belt part and installed on a hub of vehicle; a plurality of spokes arranged between the wheel part and the annular belt part. It is characterized in that the spokes are composed of a plurality of arc-shaped spokes and linear spokes. The arc-shaped spokes overlap on the periphery of the wheel part and extend according to a predetermined curvature. The linear spokes are connected to a part between the outer periphery of the arc-shaped spokes and the inner periphery of the annular belt part along an axial direction. The non pneumatic tire has the following effects: by arranging the arc-shaped spokes along a periphery direction, the bearing force for loading is improved. And the buckling when the tire is pressed is prevented. Thus, the durability and the service lifetime of the tire are improved.
Description
Technical field
The present invention relates to a kind of non-inflatable tyre, in particular, the present invention relates to a kind of durability by improving tire, extending the non-inflatable tyre in its life-span.
Background technology
Generally, non-inflatable tyre is different from currently used air-inflation tyre, owing to not putting into pressurized air, therefore disappointing such accident hazard can not occur, and it is few to have use material quantity, the simple advantage of structure design.
As an example of such non-inflatable tyre, as shown in Figure 1, the non-NULL pinch roller tire in KR JP 2004-0027984 document is recorded in.This non-NULL pinch roller tire 1 is made up of tread portion 2, the endless belt 3 strengthened and spoke 5, this tread portion 2 and earth surface, and this endless belt 3 is arranged at the inner side of tread portion 2, and this spoke 5 is fixed on inner side and the wheel hub of the endless belt 3 of enhancing or takes turns on 4.
So longitudinal stretch-draw coefficient of the endless belt 3 of enhancing is very large, though with earth surface and flattening, its length also still keeps certain at ordinary times.In addition, spoke 5, at the bend portions with earth surface, in other part, is subject to stretch-draw because its length is the characteristic of certain endless belt 3, transmits load, the weight of supported vehicle between wheel 4 and endless belt 3.But, flexing can be produced suddenly with the spoke 5 of the part of above-mentioned earth surface because of compression, therefore, need to improve the non-inflatable tyre of prior art.
Summary of the invention
The present invention invents to solve the problem, and the object of the present invention is to provide a kind of non-inflatable tyre, wherein, by preventing the flexing of spoke (ウ エ Block ス Off オ mono-Network), extends durability and the life-span of tire.
To achieve these goals, non-inflatable tyre of the present invention comprises fetus face, itself and earth surface; Circumferential band portions, it supports above-mentioned fetus face; Wheel portion, it, from above-mentioned circumferential band portions, radially leaves, and is installed on the wheel hub of vehicle; Multiple spoke portion, it is arranged at above-mentionedly takes turns between portion and circumferential band portions, it is characterized in that, above-mentioned spoke portion is made up of multiple arch spoke portion and linearity spoke portion, this arch spoke portion curvature according to the rules, overlap-extension PCR on the outer peripheral face in wheel portion, between the outer peripheral face that this linearity spoke portion is radially connected to this arch spoke portion and the inner peripheral surface of circumferential band portions.
The feature of non-inflatable tyre of the present invention is the center in trailing wheel portion, and the distance R to arch spoke portion is less than the internal diameter R1 of circumferential band portions.
The feature of non-inflatable tyre of the present invention is the center in trailing wheel portion, and the distance R to arch spoke portion is greater than 2/3 of the summation (R1+R2) of the internal diameter R1 of circumferential band portions and the external diameter R2 in wheel portion.
The feature of non-inflatable tyre of the present invention is, between the outer peripheral face and the inner peripheral surface of circumferential band portions in arch spoke portion, to connect 1 ~ 4 linearity spoke portion.
Accompanying drawing explanation
Fig. 1 is the surface structure cutaway view of state when representing non-inflatable tyre of the prior art and earth surface;
Fig. 2 is the transparent view of non-inflatable tyre of the present invention;
Fig. 3 is the front view of Fig. 2.
Detailed description of the invention
Below with reference to the accompanying drawings, the present invention is specifically described.
As shown in Figures 2 and 3, non-inflatable tyre 10 of the present invention is by fetus face 11, circumferential band portions 12, wheel portion 14 and multiple spoke portion 15 are formed, this fetus face 11 and earth surface, this circumferential band portions 12 supports above-mentioned fetus face 11, and this is taken turns portion 14 and radially leaves from above-mentioned circumferential band portions 12, be installed on the wheel hub 13 of vehicle, the plurality of spoke portion 15 is arranged at above-mentioned wheel between portion 14 and circumferential band portions 12.
Non-inflatable tyre 10 of the present invention for not adopt compressed-air actuated structure, via the load of circumferential band portions 12 and spoke portion 15 supported vehicle.That is, above-mentioned fetus face 11 is by the contact with ground, drives vehicle; Or stop because applying braking.Circumferential band portions 12 has absorption, relax function from ground or the shock and vibration from outside.Particularly, the load of the weight of spoke portion 15 supported vehicle, and prevent the flexing of tire.
The invention is characterized in that above-mentioned spoke portion 15 is made up of multiple arch spoke portion 15a and linearity spoke portion 15b.This arch spoke portion 15a curvature according to the rules, overlap-extension PCR on the outer peripheral face in wheel portion 14, between the outer peripheral face that this linearity spoke portion 15b is radially connected to this arch spoke portion 15a and the inner peripheral surface of circumferential band portions 12.
But as shown in Figure 3, the center in trailing wheel portion 14 is less than the internal diameter R1 of circumferential band portions to the distance R of arch spoke portion 15a.In addition, best, the center in trailing wheel portion 14 is greater than 2/3 of the summation (R1+R2) of the internal diameter R1 of circumferential band portions 12 and the external diameter R2 in wheel portion 14 to the distance R of arch spoke portion 15a.
On the other hand, in non-inflatable tyre 10 of the present invention, although linearity spoke portion 15b is disposed radially, this linearity spoke portion 15b quantity by the pressure that contacts to earth between the fetus face 11 of tire and ground distribution and adjust, but, preferably between the outer peripheral face and the inner peripheral surface of endless belt 12 of an arch spoke portion 15a, connect 1 ~ 4 linearity spoke portion 15b.
So, prior art is different from by the non-inflatable tyre of the present invention 10 of above-mentioned such forecast scheme configuration, along the circumferential direction arrange multiple arch spoke portion 15a, 1 ~ 4 linearity spoke portion 15b is connected in addition between the outer peripheral face and the inner peripheral surface of endless belt 12 of 1 arch spoke portion 15a, thus, effectively can transmit the load of tire, prevent flexing.
Particularly, as the result of the interpretation of structure and experiment of carrying out non-inflatable tyre, the energy of deformation density (strain energy density) of the factor of the durability of tire can be evaluated compared with the prior art shown in Fig. 1, reduce about 8%.
The present invention has following effect, that is, along the circumferential direction arranged by multiple arch spoke portion, improves the supporting power of load, and flexing when preventing tire from compressing, thus, increase durability and the life-span of tire.
Above-mentioned record is described one of outstanding embodiment of the present invention, but the present invention is not limited to this.If those skilled in the art, it must be understood that, within the scope of the invention, various change can be carried out, amendment.
