Abstract

The utility model relates to a recoil tyre-sealing part with a spoke of human power or motor vehicles. The recoil tyre-sealing part is in circular shape, the shape of the inner side is consistent with the shape of downward concave bottom of the external side of a wheel rim, the shape of the external side is consistent with the inner edge of a recoil tyre, and the center of the inner side is opened with a groove. The utility model makes up the insufficiency of a recoil tyre, the gap between the spoke and the wheel rim is effectively sealed, the recoil effect of the recoil tyre is enhanced, and the performance of the elasticity and the load can be improved.

Description

Recoil tyre-sealing part

The utility model relates to a kind of anti-stab Recoil type tyre auxiliary equipment of not inflating, and is used to make the Recoil type tyre sealing member with the manpower or the self-propelled vehicle of spoke.

Conventional tyre all need be inflated and can not be anti-stab." Recoil type tyre " of utility model communique bulletin on November 11st, 1987 is though solved this problem, but owing to gapped between spoke that passes spoke hole and wheel rim, can not seal, cause the cavity of Recoil type tyre under the load-carrying situation, can not form fully enclosed recoil chamber, thereby this tire does not have repercussion effect.

The purpose of this utility model is the sealing member that proposes a kind of Recoil type tyre, can seal the gap of spoke and wheel rim, the shortcoming that can avoid above-mentioned Recoil type tyre to exist.

The purpose of this utility model reaches by following measure: according to difform wheel rim, the utility model is made solid circular with rubber, diameter is a bit larger tham rim diameter, its inboard shape is consistent with the shape of recessed bottom, the wheel rim outside, its outer shape matches with the Recoil type tyre inner edge, the width of cross-sectional plane should be a bit larger tham tire inner chambers bore along the circumferential direction, like this, the utility model can seal mutually with the wheel rim outside, can prevent from again under the load-carrying situation, to be pressed into tire cavity, live the utility model for avoiding the spoke crown, influence sealing effectiveness, inboard central authorities have a minor groove at the utility model, and its width and the degree of depth are consistent with the diameter and the length of spoke cap head.During use, the utility model is installed earlier, Recoil type tyre is installed in the back, and both all stretch tight on the wheel rim by self elasticity.Not during load-carrying, owing between wheel rim, Recoil type tyre and the utility model three a. g. is arranged, and the recessed formation in Recoil type tyre cavity dividing wall top can not form sealed cavity along the air by-pass passage of garden Zhou Fangxiang, can not produce the recoil effect.When load-carrying, that part of tire of kiss the earth and the utility model are squeezed and are out of shape, under the caoutchouc elasticity effect, make wheel rim and spoke hole, wheel rim and tyre rim, also have between extruded each cavity to obtain good sealing, make cavity really become annular seal space, smaller volume behind this cavity pressurized, internal pressure increases, and ground-surface recoil effect is increased, thereby strengthened the elasticity and the load carrying behaviour of tire, played the recoil effect really.

The utility model has remedied the deficiency of existing Recoil type tyre, has improved recoil performance, the load carrying behaviour of Recoil type tyre, and simple in structure, and cost is low, and technology is easy to manufacture, is the vitals that Recoil type tyre is realized the recoil effect.

Below in conjunction with description of drawings manpower Recoil type tyre embodiment.

Chemical such as rubber, DOS, phthalic acid dibutyl ester, carbon black, aging inhibitor, paraffin wax, peroxide are evenly mixed by certain weight ratio,, make Recoil type tyre sealing member 2 as shown in drawings through technologies such as refining glue, sulfuration, die formings.During use, earlier the Recoil type tyre sealing member is installed on the wheel rim, spoke cap head snaps in the inboard minor groove of sealing member just, and then Recoil type tyre is installed.Recoil type tyre through the Recoil type tyre sealing member is installed can bigger raising Recoil type tyre recoil performance and load carrying behaviour.

Claims

1, a kind of Recoil type tyre sealing member is used to manpower or self-propelled vehicle Recoil type tyre with spoke, the gap between sealing wheel rim and spoke, and it is made of rubber.It is characterized in that: the sealing part is solid annular arrangement, its diameter is a bit larger tham rim diameter, its inboard shape is consistent with the recessed bottom shape in the wheel rim outside, its outer shape matches with the Recoil type tyre inner edge, the width of sealing member cross-sectional plane should be a bit larger tham Recoil type tyre inner chambers bore along the circumferential direction, inboard central authorities at sealing member have a recessed groove along circumference, and its width is consistent with the diameter and the cap head length degree of the degree of depth and spoke cap.
