CN104924859A - Variable-angle tire bead of multiply tire - Google Patents

Abstract

The invention discloses a variable-angle tire bead of a multiply tire. The variable-angle tire bead comprises bead toes located at the bottom of the tire bead. The bead toes comprise the outer bead toes and the inner bead toes. The inner toe angle of each inner bead toe corresponds to the angle of a steel rim, and the outer toe angle of each outer bead toe is larger than the corresponding inner toe angle. The difference between each outer toe angle and the corresponding inner toe angle is not larger than 5 degrees. The angle of each inner toe angle ranges from 0 degree to 3 degrees. The length of each outer bead toe is equal to that of the corresponding inner bead toe. The variable tire toe angle design is adopted, so that it is guaranteed that the tire bead is tightly matched with the steel rim, and the tire is easy to assemble and disassemble.

Description

Multiply tire varied angle tyre bead

(1) technical field:

The present invention relates to tire construction, be specially a kind of multiply tire varied angle tyre bead.

(2) background technology:

The tyre bead of tire is the part directly contacted with tyre rim, and the angle of the tire toe of bead base, according to the angle design of the tyre rim bead seat used, is generally designed to single angle.

Because the tyre bead of multiply tire is wider, often reaching the extreme value of wheel rim bead seat width, causing tire very difficult when loading and unloading.

(3) summary of the invention:

For the deficiencies in the prior art, technical matters to be solved by this invention proposes a kind of multiply tire varied angle tyre bead being convenient to Assembly &Disassembly on tyre rim.

The technical scheme of the multiply tire varied angle tyre bead of the present invention that can solve the technical problem, comprise the tire toe of bead base, described tire toe comprises outside tire toe and inner side tire toe, the angle of the corresponding tyre rim in interior toe angle of described inner side tire toe, and the outer toe angle of described outside tire toe is greater than interior toe angle.

The present invention adopts and increases outer toe angle number, and expand the gap between outside tire toe and tyre rim, what be convenient to handling tool enters operation.

Namely will be easy to handling, ensure closely cooperating of tyre bead and wheel rim again, the number of degrees difference at described outer toe angle and interior toe angle is not more than 5 °

In conventional design, the number of degrees value at described interior toe angle is between 0 ° ~ 3 °.

The axial length of outside tire toe and inner side tire toe can be selected equal.

Beneficial effect of the present invention:

Multiply tire varied angle tyre bead of the present invention adopts the design becoming tire toe angle, namely ensure that closely cooperating of tire bead and tyre rim, is convenient to again the handling of tire.

(4) accompanying drawing illustrates:

Fig. 1 is the structural representation of one embodiment of the present invention.

Figure number identifies: 1, tyre bead; 2, outside tire toe; 3, inner side tire toe.

(5) detailed description of the invention:

Below in conjunction with accompanying drawing illustrated embodiment, technical scheme of the present invention is described further.

Multiply tire varied angle tyre bead of the present invention comprises the tire toe bottom tyre bead 1, and tire toe and the tyre rim of described tyre bead 1 closely cooperate, and described tire toe comprises the outside tire toe 2 outside tyre bead 1 and the inner side tire toe 3 inside tyre bead 1, as shown in Figure 1.

Wherein:

The angle of interior toe angle (∠ 1) the corresponding tyre rim of described inner side tire toe 3.

The number of degrees value of described interior toe angle (∠ 1) is between 0 ° ~ 3 °.

The outer toe angle (∠ 2) of described outside tire toe 2 is greater than the interior toe angle (∠ 1) of inner side tire toe 3.

The outer toe angle (∠ 2) of described outside tire toe 2 is not more than 5 ° with the number of degrees difference at the interior toe angle (∠ 1) of inner side tire toe 3.

The axial length of described outside tire toe 2 equals the axial length of inner side tire toe 3.

Claims (4)

1. multiply tire varied angle tyre bead, comprise the tire toe of tyre bead (1) bottom, it is characterized in that: described tire toe comprises outside tire toe (2) and inner side tire toe (3), the angle of the corresponding tyre rim in interior toe angle of described inner side tire toe (3), and the outer toe angle of described outside tire toe (2) is greater than interior toe angle.

2. multiply tire varied angle tyre bead according to claim 1, is characterized in that: the number of degrees difference at described outer toe angle and interior toe angle is not more than 5 °.

3. multiply tire varied angle tyre bead according to claim 1 and 2, is characterized in that: the number of degrees at described interior toe angle are 0 ° ~ 3 °.

4. multiply tire varied angle tyre bead according to claim 1 and 2, is characterized in that: the axial length of described outside tire toe (2) and inner side tire toe (3) is equal.
