Abstract

Disclosed is a tire bead ring winding disk which comprises a first portion, a second portion and a third portion. The first portion and the second portion are half-moon plates with the same shapes and respectively fixed to the left upper portion and the right upper portion of the third portion; the upper half portion of the third portion is in a shape similar to an isosceles triangle; the lower half portion of the third portion is in the shape of a semicircle; straight edges of the first portion and the second portion are respectively attached to two beveled edges on the upper half portion of the third portion in the shape similar to the isosceles triangle after the first portion and the second portion are fixed to the third portion; and a circle is jointly formed by outer circular arcs of the first portion and the second portion and the lower half portion of the third portion in the shape of the semicircle. The tire bead ring winding disk has the advantages that a whole body is formed by a lower half-moon plate and a diamond block, freedom degree of the bead ring winding disk in working process is decreased, and accordingly factors causing the bead ring winding disk to sway are reduced.

Description

The bead wire ring winding disc

[technical field]

The utility model is about the doughnut accessory, particularly about the bead wire ring winding disc.

[background technology]

The binding site of tire and wheel rim---wire loop is that tire is securely fixed on the wheel rim, vehicle load is delivered to the critical piece of tire.The quality of wire loop directly has influence on gas retaining, comfortableness and the security of vehicle.

At present, the winding disc that is used to make wire loop be by the central authority diamond block with 2 first half of the month plate, 2 lower meniscus be connected, 4 meniscal external arc form a circle.When the wire loop winding disc is in running order, the meniscal flexible little cylinder supports that only depends on the diamond block, under action of centrifugal force, meniscal cylindrical can produce displacement and make round distortion for oval.Secondly, adopt set bolt to be connected between meniscus and the central authority diamond block, the wearing and tearing of set bolt also cause meniscus to produce in certain scope rocking, it is this because its design limitations---the free degree is too much, cause the interior girth fluctuation range of wire loop normally between 0～1.5mm, sometimes reach more than the 2.0mm, have a strong impact on the wire loop quality.

And wire loop is not of uniform size, can cause vehicle both sides tire bead decentraction and influences riding comfort, and the excessive tire that may cause of wire loop comes off from wheel rim, thereby influences ride safety of automobile.Therefore, excellent in design can overcome wire loop twine in the big wire loop winding disc of girth fluctuation just seem particularly important.

[utility model content]

Technical problem to be solved in the utility model is to provide a kind of bead wire ring winding disc that solves the bigger problem of the following in working order interior girth fluctuation range that too much causes because of the free degree of existing wire loop winding disc.

The utility model solves the problems of the technologies described above by the following technical programs: a kind of bead wire ring winding disc, comprise first, second portion, and third part, described first, second portion is the identical meniscus of shape, be separately fixed at the upper left side and the upper right side of third part, the first half of described third part is divided into approximate isosceles triangle, the latter half is semicircle, after described first and second portion are fixed on third part, the straight flange of first and second portion is fitted with two hypotenuses of the first half that becomes isosceles triangle of third part respectively, and circle of the external arc of first and second portion and the common composition of the external arc that becomes semicircular the latter half of third part.

As an embodiment, this bead wire ring winding disc also comprises 2 limited blocks, described each limited block comprises riser, transverse sheet and top screw, and the groove that a width equals the transverse sheet width is laterally offered at the described riser back side, and the top of described riser offers the screw of conduction through concave trough;

The transverse sheet of one of them limited block is fixed on first with screw, the long limit of transverse sheet and the straight flange of first are fitted, the two ends of Dui Ying riser lock in first and third part by screw respectively with it, described transverse sheet is stuck in the groove of riser, and transverse sheet and riser right-angled intersection, described top screw is against on the described transverse sheet behind the described screw of top precession of riser;

The transverse sheet of another limited block is fixed on second portion with screw, the long limit of transverse sheet and the straight flange of second portion are fitted, the two ends of Dui Ying riser lock in second portion and third part by screw respectively with it, described transverse sheet is stuck in the groove of riser, and transverse sheet and riser right-angled intersection, described top screw is against on the described transverse sheet behind the described screw of top precession of riser.

Whole structure is best when the position of described 2 limited blocks lays respectively at joint place middle of the centre of joint place of described first and third part and described second portion and third part.

The advantage of the utility model bead wire ring winding disc is: lower meniscus and diamond block are formed an integral body, reduced the wire loop winding disc free degree in the course of the work, thereby reduced the factor that causes that the wire loop winding disc rocks; Plate increase in first half of the month limited block can effectively be eliminated the meniscus displacement that causes because of centrifugal force, also can eliminate the wire loop winding disc that causes because of the bolt wearing and tearing simultaneously and rock.The girth fluctuation range can be stabilized in 0～0.5mm scope in the wire loop that novel tire wire loop winding disc twines out, thereby has improved tyre element greatly---the quality of wire loop.
