Background technology

Along with increasing gradually of the car accedent caused because of tyre explosion, brought great puzzlement to people's living safety, at present, a lot of for the hub design kind that prevents from having an accident after tyre explosion, 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 to 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 utility model 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 utility model is taked 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 utility model 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 utility model 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 utility model further technical scheme is: be provided with elastomeric pad between the inner of described timberer's font and inside and outside wheel rim joint face, described elastomeric pad is rubber, silica gel or plastic cement.

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

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

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

The utility model further technical scheme is: described spoke is arranged on outer rim.

The utility model further technical scheme is: described attaching parts is bolt.

The beneficial effects of the utility model are:

One, the utility model is owing in the wheel hub periphery, being provided with explosion-proof support, and when vehicle is 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, leave between explosion-proof support and tire and clash into space, can guarantee the comfort level in the Vehicle Driving Cycle process.

Three, be coated with elastomeric material in explosion-proof support outer end and the inner, 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 utility model.

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, between support 3 the inners and inside and outside wheel rim joint face, is provided with rubber sheet gasket 6 and rubber sheet gasket 9.

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.
