Abstract
The invention discloses a section structure of a motorcycle tire. The motorcycle tire comprises a tire tread part, a tire bead part and a tire lip part, wherein the tire bead part consists of an upper circular arc line and a lower straight line; an included angle formed between the circular arc line and the straight line is an obtuse angle; saw-toothed patterns are arranged all around the straight line; the tire bead part and the tire lip part are chamfered. The tire bead part which consists of the circular arc line and the straight line is approximate to a broken line, so that the rigidity of the tire bead part is ensured, the tire and a rim can be well embedded, and the problem of separation of the tire lip part from the rim is solved; moreover, by additionally arranging the saw-toothed patterns on the straight line of the tire bead part, the whole weight of the tire can be reduced; by chamfering the tire bead part and the tire lip part, stress concentration between the tire bead part and the tire lip part can be prevented, and the strength of the tire bead part can be ensured; when the tire runs in an internal pressure reduction state, the tire can be fastened with the rim, the air preservation performance is improved, and a motorcycle can reach the nearest maintenance point.
Description
Technical field
The present invention relates to a kind of motor cycle tire, refer to especially a kind of motor cycle tire section structure.
Background technology
As shown in Figure 1, the profiled outline of existing motorcycle tire 10 ' generally comprises fetus face 1 ', tyre bead section 2 ' and tire lip 3 ', for promoting tyre bead section 2 ', have good absorption road shocks power and the function of vibration, improve traveling comfort and cushion characteristic, tyre bead section 2 ' generally adopt evagination circular arc line 11 ' design and with 3 ' the convex circular arc line 12 ' smooth connection of tire lip so that better coordinate with wheel rim 4 '.But the tire of this kind tyre bead section 2 ' design, tyre bead section 2 ' rigidity a little less than, when tire 10 ' travels under deflation state, tire lip 3 ' weakens with the squeeze pressure of wheel rim 4 ', tire 10 ' reduces with the inlay resultant force of wheel rim 4 ', the problem that therefore exists tire lip 3 ' easily to break away from from wheel rim 4 '.
Again as shown in Figure 2, the evagination circular arc line 11 ' of existing motorcycle tire 10 ' ' if by tyre bead section 2 ' ' ' radian strengthen near a straight line and with tire lip 3 ' ' convex circular arc line 12 ' ' and interconnect and roughly become one rectangular-shaped with a straight line, make tyre bead section 2 ' ' play a supporting role, better chimeric with wheel rim 4 ', ' with the wheel rim 4 ' ' problem that breaks away from that effectively prevents tire lip 3 ', when tire 10 ' ' be under the low state of internal drop while travelling, can guarantee to arrive nearest maintenance point, but its tyre bead section 2 ' is set so ' thickness B ' thickening, the tire overall weight will increase, oil consumption is risen.
Based on above problem, this case just produces thus.
Summary of the invention
The object of the invention is to provide a kind of motor cycle tire section structure, can alleviate tire weight, reduces oil consumption, when tire travels under deflation state, promotes the gas retaining energy of tire, effectively prevents the problem that bead part and wheel rim break away from, and improves the tire running safety.
For achieving the above object, solution of the present invention is:
A kind of motor cycle tire section structure, this tire comprises fetus face, tyre bead section and tire lip, wherein: this tyre edge section is by the circular arc line on top and the rectilinear(-al) of bottom, the obtuse-angulate angle of circular arc line and linear, circle arranges the sawtooth lines on straight line, between tyre bead section and tire lip, is the rounding setting simultaneously.
Described angle is set to 140 ° ~ 160 °.
Described sawtooth lines and axial or radial parallel setting, the degree of depth of sawtooth lines is 0.2 ~ 1.5mm.
The rounding of described tyre bead section and tire lip is set to 0.2 ~ 1.5mm.
After adopting such scheme, the present invention mainly improves by tire section profile optimal design, tyre edge section by circular arc line and rectilinear(-al), and the obtuse-angulate angle of circular arc line and linear, make tyre bead section be roughly a broken line, guarantee tyre bead section rigidity, make tire and wheel rim better chimeric, prevent the problem that tire lip and wheel rim break away from; Separately at tyre bead section straight line portion, increase the design of zig-zag lines, can whole alleviate the weight of tire; Tyre bead section and tire lip are carried out to the rounding design, and can to prevent between tyre bead section and tire lip producing stress concentrated, guarantee tyre bead section intensity, when tire is under the low state of internal drop while travelling, tire can fasten wheel rim, promote the gas retaining energy, can arrive nearest maintenance point.
The accompanying drawing explanation
Fig. 1 is the cross-section structure of existing motor cycle tire;
Fig. 2 is the cross-section structure of another existing motor cycle tire;
Fig. 3 is the cross-section structure of motor cycle tire of the present invention;
Fig. 4 is the partial enlarged drawing of Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing, explain embodiments of the present invention:
As shown in Figure 3,4, the present invention has disclosed a kind of motor cycle tire section structure, and vertical direction is for radially, and horizontal direction is axial.This tire 10 comprises fetus face 1, tyre bead section 2 and tire lip 3, tyre bead section 2 profiles to tire carry out adjusted design, namely this tyre edge section 2 is comprised of the circular arc line 11 on top and the straight line 12 of bottom, circular arc line 11 and the obtuse-angulate angle α of straight line 12 shape, this angle α is set to 140 ° ~ 160 °, makes tyre bead section 2 be roughly a broken line, so can effectively guarantee tyre bead section 2 rigidity, make tire 10 and wheel rim 4 better chimeric, prevent the problem that tire lip 3 and wheel rim 4 break away from; Circle increases the design of sawtooth lines 13 on straight line 12 in addition, the sawtooth lines can with axial or radial parallel setting, the depth H of sawtooth lines 13 is 0.2 ~ 1.5mm, so effective attenuate tyre bead sizing material thickness B, to alleviate the tire overall weight.
For preventing between tyre bead section 2 and tire lip 3 that producing stress concentrates, tyre bead section 2 is carried out to the rounding design with tire lip 3, its rounding R is set to 0.2 ~ 1.5mm.So arrange, when tire is under the low state of internal drop while travelling, tire 10 can fasten rim, promotes the gas retaining energy, can arrive nearest maintenance point.
After using the technology of the present invention, select the specification of 4.60-16 TL for motor cycle rear wheel, each testing tire be loaded on the wheel rim of MT2.15X16 and fill the interior pressure of 50kPa, be arranged on motor bike the travelled distance that carries out the real vehicle test evaluation and travel under low blast, control stability and fuel-efficient situation, by the sensory evaluation of chaufeur, with past case, to compare, tread life of the present invention is long, more fuel-efficient, at low blast, travelling, to control stability better.
