Abstract

The present invention belongs to the technical field of vehicle inner tubes, and relates to an anti-squeezing vehicle inner tube, which is opening, wherein the end surfaces on both ends of the inner tube have included angles in a non-inflation state, and the included angle is expanded from the outer circle of the inner tube to the inner circle of the inner tube. According to the present invention, the end surfaces of both ends are changed into the slope joint, such that the folding mark generation and the breaking of the inner tube inner circle can be effectively prevented, and the service life of the inner tube can be effectively prolonged.

Description

Anti-extrusion inner tube of vehicle tyre

Technical field

The invention belongs to inner tube of vehicle tyre technical field, more particularly to a kind of anti-extrusion inner tube of vehicle tyre.

Background technology

Inner tube of vehicle tyre in the market, when the inner tube of a tyre is changed, it is necessary to first unload whole wheel, program With man-hour upper too complex, waste time and energy.

In addition, existing split type inner tube of a tyre two ends end face is in parallel plane (two ends end under non-inflated state Face place plane is through inner tube of a tyre center), due to inner tube of a tyre inner circle and the difference of cylindrical external diameter, two ends end after inflation Inner circle is also easy to produce extruding at face, forms folding line, and easy jackknifing affects the service life of the inner tube of a tyre.

The content of the invention

The purpose of the present invention is to overcome split type inner tube of a tyre two ends end in prior art to be also easy to produce extruding, Forming folding line affects the deficiency of service life of the inner tube of a tyre, there is provided a kind of anti-extrusion inner tube of vehicle tyre.

The technical solution adopted for the present invention to solve the technical problems is：A kind of anti-extrusion inner tube of vehicle tyre, institute It is in open to state the inner tube of a tyre, and during non-inflated state, inner tube of a tyre two ends end face has angle, and the angle is by interior The cylindrical interior circular direction to the inner tube of a tyre of tire is in expansion shape.

Further, extruding is produced to be prevented effectively from inner tube of a tyre two ends joint inner circle, forms folding line, the folder Angle is less than or equal to 30 ° more than 0 °.

Preferably, according to the ductility of rubber, described angle is 10 °.

Beneficial effect：The present invention can be prevented effectively by way of two ends end face is improved to into miter joint Inner tube of a tyre inner circle produces folding line, fracture, effectively improves the service life of the inner tube of a tyre.

Specific embodiment

Embodiment 1

A kind of anti-extrusion inner tube of vehicle tyre, the inner tube of a tyre 10 is in open, as shown in figure 1, during non-inflated state, The two ends end face 3 of the inner tube of a tyre 10 have angle α (i.e. non-inflated state when, in the place plane of two ends end face 3 deviates The center of circle of tire 10), the angle α is in expansion shape from cylindrical 1 to the direction of inner circle 2, according to the ductility of rubber, institute The angle α stated is preferably 10 °.

The principle of the invention is as follows：During inflation, the inner tube of a tyre 10 cylindrical 1 towards the external expansion of the inner tube of a tyre 10, the inner tube of a tyre 10 inner circle 2 towards the internal expansion of the inner tube of a tyre 10, because the two ends end face 3 of the inner tube of a tyre 10 is provided with the application Angle α, as shown in figure 1, therefore can spell at cylindrical 1 and inner circle 2 of the inner tube of a tyre 10 after the completion of inflation Be connected into unitary circular, as shown in Fig. 2 so effectively prevent at the two ends end face 3 of the inner tube of a tyre 10 inner circle 2 due to Expansion produces extruding, forms the phenomenon of folding line, so as to avoid the use of the inner tube of a tyre 10 during friction increase, easily The phenomenon of jackknifing, substantially increases the service life of the inner tube of a tyre 10.

It should be appreciated that specific embodiment described above is only used for explaining the present invention, limit is not used to The fixed present invention.The obvious change extended out by the spirit of the present invention or variation are still in this Among bright protection domain.

Claims
