Abstract

The invention discloses an explosion-proof wheel hub for a tire. The explosion-proof wheel hub comprises an outer wheel rim, an inner wheel rim, spokes, a support and a flange at the joint of the outer wheel rim and the inner wheel rim, wherein opposite annular grooves are arranged at an abutting end of the outer wheel rim and the inner wheel rim, the cross section of the support is I-shaped, an elastic rubber material is arranged at the outer end of the support, a rubber gasket is arranged at the inner end of the support, the inner end of the support is inserted into the annular grooves of the inner wheel rim and the outer wheel rim and connected with the wheel rims to form an integral body, a flange joint is provided with the rubber gasket, the outer wheel rim and the inner wheel rim are connected and fixed through a connecting piece at the flange, and bumping space is left between the outer end of the support and the bottom in the tire. The explosion-proof wheel hub provided by the invention can prevent accidents caused by tire burst during driving, allows driving to be continued during tire burst without damage to the tire and does not influence the comfort level of driving; since an assembling structure is adopted for the inner wheel rim and the outer wheel rim, dismounting and mounting are facilitated, and thus, replacing and repairing efficiency of the tire with the explosion-proof wheel hub can be substantially improved.

Description

A kind of tire anti-explosion formula wheel hub

Technical field

The present invention relates to the wheel hub field, be specifically related to a kind of tire anti-explosion formula wheel hub.

Background technology

Along with increasing gradually of the car accedent caused because of tyre explosion, brought great puzzlement for people's living safety, at present, for preventing that the hub design kind had an accident after tyre explosion is a lot, but the structure that the tire anti-explosion in existing design is designed with is very complicated, and productive costs is higher; What have is designed to integral body by wheel hub and explosion protection, install extremely inconvenient, even explosion protection is carried out to the piecemeal installation, because of the wheel rim of wheel hub both sides stop and tire and riot gear between gap less, usually also need special instrument and equipment and professional just can complete erection work, this just makes auto consumer in use, runs into and needs the cost of replacing or retread a tyre too high, brings certain difficulty for promoting the use of of tire anti-explosion wheel hub.

Summary of the invention

In order to solve the deficiency of current tire anti-explosion hub design, the invention provides a kind of tire anti-explosion formula wheel hub, not only can avoid the accident of automobile because blowing out and occurring, and be convenient to remove and install.

The technical scheme that the present invention takes is:

Tire anti-explosion formula wheel hub, comprise wheel rim and spoke, described wheel rim periphery is provided with the explosion-proof support of tire, described wheel rim comprises interior wheel rim and outer rim, the inner of described support is connected in the coupling end of interior wheel rim and outer rim, the coupling end inboard of described interior wheel rim and outer rim is provided with flange connector, and described flange connector connects by attaching parts.

The further technical scheme of the present invention is: described interior wheel rim is provided with relative circular groove with the outer rim coupling end, and described support is I shape along the wheel hub axial cross section, and the circular groove that interior wheel rim and outer rim are inserted respectively in the inner of described timberer's font is connected.

The present invention further technical scheme is: the outer end of described timberer's font is coated with elastomeric material, and described elastomeric material is rubber, silica gel or plastic cement.

The present invention further technical scheme is: between the inner of described timberer's font and inside and outside wheel rim joint face, be provided with elastomeric pad, described elastomeric pad is rubber, silica gel or plastic cement.

The present invention further technical scheme is: described support is annular arrangement along the wheel hub lateral cross section, and described annular arrangement is comprised of four arc unit at least.

The present invention further technical scheme is: leave the shock distance between described support outer end and tire inner bottom part.

The present invention further technical scheme is: described shock distance is 1 centimetre of left and right.

The present invention further technical scheme is: described spoke is arranged on outer rim.

The present invention further technical scheme is: described attaching parts is bolt.

The invention has the beneficial effects as follows:

One, the present invention is owing in the wheel hub periphery, being provided with explosion-proof support, and when vehicle was blown out in the process of moving, explosion-proof support can play the effect of support tire, can effectively prevent the safety misadventure that vehicle is blown out suddenly and caused in the process of moving.

Two, between explosion-proof support and tire, leave and clash into space, can guarantee the comfort level in the Vehicle Driving Cycle process.

Three, in explosion-proof support outer end and the inner, be coated with elastomeric material, when vehicle is blown out in the process of moving, not only can continue to travel, and can avoid tire and wheel hub to be destroyed, and can not jolt.

Four, hub design is become to interior outer rim splicing structure, explosion-proof support is connected with the plug-in type that is connected to of interior outer rim simultaneously, explosion-proof support is comprised of polylith arc unit in addition, greatly facilitate dismounting and installation to tire, reduce maintenance cost, be conducive to popularization and the use of tire anti-explosion wheel hub.

The accompanying drawing explanation

Fig. 1 is the axial partial cutaway schematic of the present invention.

Fig. 2 is A-A generalized section in Fig. 1.

The specific embodiment

Tire anti-explosion formula wheel hub as illustrated in fig. 1 and 2, comprise wheel rim and spoke, and described wheel rim periphery is provided with the explosion-proof support 3 of tire, and described wheel rim comprises interior wheel rim 2 and outer rim 1, and interior wheel rim 2 is provided with relative circular groove with outer rim 1 coupling end; Described support 3 is I shape along the wheel hub axial cross section, the inner of support 3 is connected in the coupling end of interior wheel rim 2 and outer rim 1, the coupling end inboard of described interior wheel rim 2 and outer rim 1 is provided with flange connector 8, described flange connector 8 connects by bolt 7, support 1 outer end is coated with elastomeric material 4, is provided with rubber sheet gasket 6 and rubber sheet gasket 9 between support 3 the inners and inside and outside wheel rim joint face.

During installation, first support 1 is installed in the inner splicing of tire 10, the inner of support 1 I shape is inserted respectively interior wheel rim 2 and is connected with the circular groove of outer rim 1, finally outer rim 1 and interior wheel rim 2 are connected and fixed by 4 bolts 7 at flange 8 places, support outer end and tire inner bottom part leave and clash into 1 centimetre, space.

During dismounting, first outer rim 1 and interior wheel rim 2 are all turned at 4 bolts 7 at flange connector 8 places, then pulled down respectively interior wheel rim 2 and outer rim 1, finally take out support 1, tire is changed and keeped in repair.
