Abstract
The utility model relates to a tire, comprising a tire ring. The tire ring is provided with a tire ring bottom surface which is contacted with a rim. The tire ring bottom surface is provided with ring shaped protuberances along the circumferential direction of the rim. The curvature radius of the surface of the ring shaped protuberance is 5-15mm, and the width of 5-10mm. The distance of the highest point of the ring shaped protuberance to the tire ring bottom surface is 1-1.5mm. The good effect of precluding the air can be achieved when the tire is vulcanized by using the structure, which can solve the problem of faulty molding of the part in the tire production process. In the using process, the tire ring can be closely stuck on the edge of the rim under the pressure of air inside the tire by using the tire designed based on the tire ring structure. The air tightness between the tire and the rim is enhanced. The tire of the utility model is particularly suitable for the tire without inner tube.
Description
(1) technical field:
The utility model relates to a kind of tire.
(2) background technology:
The cover tire of tire is the housing that bears motive power, is made up of tyre surface, sidewall, cushion layer (or bracing ply), carcass plies and tyre bead.Wherein tyre bead is the part of mounting of tyre on wheel rim, and the main effect of tyre bead is tire is fixed on the wheel rim, and opposing makes cover tire break away from the application force of wheel rim when automotive operation.In the existing air-inflation tyre, when tire is very low even travel when completely losing at pressure, tyre bead is very big from the probability that rim edge breaks away from, and exists dangerously significantly, therefore must guarantee the air-tightness between tire and the wheel rim.For the air-inflation tyre that the inner tube of a tyre is arranged, its tyre bead outside is generally smooth straight, but owing to be provided with rim strip between the inner tube of a tyre and wheel rim, this rim strip can be realized the air-tightness between tire and the wheel rim.For the free from inflatable inner tube tire, under the effect of air-tightness between tire and the wheel rim by the tire inner air pressure tyre bead is close on the rim edge, there are two kinds of shapes in its tyre bead outside, a kind of is smooth straight structure, the tyre bead of this structure can not play the effect of emptying gas when the tyre vulcanization moulding, might cause this position to produce the starved phenomenon; Another kind of bead structure is for being provided with the concentric circular groove line in some roads on the tyre bead outside, though this structure can play the effect of emptying gas, the air-tightness between its tire and the wheel rim is not ideal enough.
(3) utility model content:
The utility model will provide a kind of can play the deaeration effect when sulfuration, strengthen bubble-tight tire between tire and the wheel rim.
This novel a kind of tire comprises tyre bead, and tyre bead has and the contacted tyre bead of wheel rim bottom surface, and be with the difference of existing tire bead: described tyre bead bottom surface is provided with the annular projection that is provided with along the wheel rim circumferencial direction.
The surface of described annular projection is an arcwall face, and its radius of curvature is generally 5-15mm.
The width of described annular projection is generally 5-10mm, and the vertical distance between the highest point of this annular projection and the tyre bead bottom surface is in the 1-1.5mm scope.
The number of annular projection can be determined as required on the described tyre bead bottom surface, is generally the 1-3 road.
This novel described tire is a tubeless tires.
A kind of tire of the utility model, employing is provided with the annular projection that is provided with along the wheel rim circumferencial direction on tire bead and the contacted tyre bead of wheel rim bottom surface, and the radius of curvature on this annular projection surface is 5-15mm, width is 5-10mm, in conjunction with the highest point of this annular projection structure to the vertical distance of 1-1.5mm between the tyre bead bottom surface, make tire when sulfuration, can play the effect of good deaeration, produce the problem of starved when having solved tire production at this position, and adopt above-mentioned bead structure design-calculated tire, in the use, under the effect of tire inner air pressure, make tyre bead more closely be attached on the rim edge, strengthen air-tightness between tire and the wheel rim, be particularly suitable for tubeless tires.
(4) description of drawings:
Fig. 1: the structural representation of a kind of embodiment of the utility model;
Fig. 2: the partial enlarged drawing of annular projection in the embodiment shown in Figure 1.
Reference numeral: 1 tyre bead; 2 annular projections; 3 tyre bead bottom surfaces; W is the width of annular projection; H is the vertical distance of the highest point of annular projection to the tyre bead bottom surface; R is the radius of curvature of annular projection.
(5) specific embodiment:
In embodiment shown in Figure 1, this novel a kind of tire comprises tyre bead 1, is provided with the annular projection 2 that 3 roads are provided with along the wheel rim circumferencial direction on tyre bead 1 and the contacted tyre bead of wheel rim bottom surface 3; The surface of described annular projection 2 is an arcwall face, and its radius of curvature R is 10mm, and width W is 8mm, and the highest point of this annular projection 2 is 1mm to the vertical distance H of tyre bead bottom surface 3.
Claims (5)
1, a kind of tire comprises tyre bead (1), and tyre bead (1) has and the contacted tyre bead of wheel rim bottom surface (3), it is characterized in that: described tyre bead bottom surface (3) is provided with the annular projection (2) that is provided with along the wheel rim circumferencial direction.
2, tire according to claim 1 is characterized in that: the surface of described annular projection (2) is an arcwall face, and its radius of curvature (R) is 5-15mm.
3, tire according to claim 1 and 2 is characterized in that: the width (W) of described annular projection (2) is 5-10mm, and the vertical distance (H) between the highest point of this annular projection (2) and tyre bead bottom surface (3) is 1-1.5mm.
4, tire according to claim 1 and 2 is characterized in that: the number of annular projection (2) is the 1-3 road on described tyre bead (1) bottom surface.
5, tire according to claim 1 and 2 is characterized in that: described tire is a tubeless tires.
