Problems solved by technology

[0005] When the tire 10'' is running under the state of reduced internal pressure, it can guarantee to reach the nearest maintenance point, but if the thickness B' of the bead part 2'' is thickened in this way, the overall weight of the tire will increase and the fuel consumption will increase

Embodiment approach

[0021] Such as image 3 , 4 As shown, the present invention discloses a section structure of a motorcycle tire, the vertical direction is radial, and the horizontal direction is axial. The tire 10 includes a tread portion 1, a bead portion 2 and a bead portion 3, and the profile of the bead portion 2 of the tire is adjusted and designed, that is, the tire bead portion 2 is composed of an upper arc line 11 and a lower straight line 12 , the arc line 11 and the straight line 12 form an obtuse angle α, the angle α is set to 140°~160°, so that the bead portion 2 is roughly a broken line, so that the rigidity of the bead portion 2 can be effectively ensured, and the tire 10 Better fitting with the rim 4 to prevent the bead lip 3 from detaching from the rim 4; in addition, the design of the sawtooth pattern 13 is added to the entire circumference of the straight line 12. The sawtooth pattern can be set parallel to the axial or radial direction, and the sawtooth pattern 13 The dept...

Abstract

Disclosed is a section structure of a motorcycle tire. The tire includes a tread part, sidewall parts, and bead parts. Each sidewall part is composed of an upper circle line and a lower straight line, wherein an obtuse angle is formed between the circle line and the straight line. Toothed lines are arranged on the straight lines in a full circumferential manner, and rounding is arranged between the sidewall parts and the bead parts. Circle lines and straight lines form the sidewall parts and make the sidewall parts be broken lines. Rigidity of the sidewall parts is ensured, so that the tire can well engage with a rim, and bead parts are protected from being separated from the rim. Further, toothed line design is added at straight lines of the sidewall parts, thereby reducing the weight of the whole tire. Rounding is arranged between the sidewall parts and the bead parts, so that stress concentration is prevented from generation between the sidewall parts and bead parts, and the strength of the bead parts is ensured. When the tire travels in a state of lower inner pressure, the tire can buckle the rim, and gas retention of the tire is improved for getting to the nearest maintenance point.

Description

technical field [0001] The invention relates to a motorcycle tire, in particular to a section structure of a motorcycle tire. Background technique [0002] Such as figure 1 As shown, the cross-sectional profile of the existing motorcycle tire 10' generally includes a tread portion 1', a bead portion 2' and a bead portion 3', in order to enhance the bead portion 2', which has a good ability to absorb road impact and vibration features for improved comfort and [0003] For impact performance, the bead portion 2’ is generally designed with an outer convex arc line 11’ and is smoothly connected with the inner convex arc line 12’ of the bead portion 3’, so as to better cooperate with the rim 4’. However, in the tire with this kind of bead portion 2', the rigidity of the bead portion 2' is relatively weak. Since the fitting force between ' and the rim 4' is reduced, there is a problem that the bead portion 3' is easily detached from the rim 4'. [0004] Another example figur...
