Description
Technical field
The utility model relates to a kind of vehicular spare parts, particularly relates to integrated hub assembly.
Background technology
Vehicle under steam, it is breakneck that tire slips into race from the disengaging of wheel hub bead seat, once tire comes off from wheel hub bead seat slip into race, tire will be caused asynchronous with wheel hub, because brake system and steering swivel system have come by controlling wheel hub, tire can cause turning to and braking out of control of vehicle after wheel hub bead seat departs from, and may cause serious traffic accident.Vehicle is when desert traveling or land locomotion, and we can lower tire pressure the earth-grasping force increasing tire usually, and vehicle tyre travels under infrabar or 0 air pressure (vehicle flat tire) situation, and tire is very easy to come off from the bead seat of wheel hub.
In order to prevent tire from departing from from wheel hub bead seat, prior art mainly adopts anticreep wheel hub to come off to prevent tire from wheel hub bead seat.The mode of anticreep wheel hub mounting tyre is different from conventional boss, and tyre rim is not outwardly be stuck in wheel hub inner ring, and is placed on the outer ring of wheel hub, and then roller hub anticreep trim ring compresses and locks tyre edge.But this anticreep wheel hub exists certain defect: 1, adopt anticreep wheel hub installation process to require higher, whether whether the contact surface of tire and anti-knocking over fitted and directly can be affected tire and leak gas, complex installation process complexity; 2, when high vehicle speeds or when running into hole bank, rising tire pressure will raise by tyre temperature, pressure suffered by tire is largely converted into the pressure to anti-knocking over, now be easy to cause anti-knocking over rupture and cause tire knocking over, the anti-knocking over fracture of one flies out, other people life may be injured and cause other people property damage, its two tire is once knocking over, to badly influence the safety of navigating mate and the personnel of riding, therefore U.S. law clearly forbids that the vehicle installing anticreep wheel hub travels on highway; 3, wheel hub is heavier, affects oil consumption; 4, cost is high.
Departing from from wheel hub bead seat to prevent tire and slip into race, prior art is mainly installed annular support band and is sealed up by wheel hub race in wheel hub race, prevents tire bead from slipping into race, thus ensures that tire is synchronous with wheel hub.But this technology exists certain defect: 1, complex installation process is complicated, tyre dismounting is inconvenient.In installation process, first tire is installed on wheel hub, then adopts special tool tyre collapse to be exposed wheel hub race installation annular support band, then give tyre inflating; In unloading process, first adopt special tool tyre collapse to be exposed wheel hub race annular support band and removed, then at remove a tyre; 2, wheel hub is heavier, affects oil consumption; 3, cost is high.
The utility model provides novel hub assembly, can solve the shortcoming of above-mentioned two schemes well.This novel hub assembly is applicable to the Wheeling System not having the inner tube of a tyre, and it is in integrated hub wheel rim race, install can be diametrically movable tire bead active block stop, by sliding and/or rotating tire tyre bead active block stop, can dismounting tire easily.
In tire installation process, slide and/or rotating tire tyre bead active block stop, make it not exceed wheel hub wheel rim bead seat hump, thus ensure that tire is installed smoothly; After the bead seat that tire bead is installed to integrated hub, by sliding and/or rotating tire tyre bead active block stop, making its baffle structure exceed wheel hub wheel rim bead seat hump and not exceeding the maximum profile of wheel hub, stopping that tire bead slips into wheel hub race; When tire travels under 0 air pressure or infrabar situation, thus ensure that wheel hub is synchronous with tire, prevent from turning to and brake out of control.
In tire dismantling process, by sliding and/or rotating tire tyre bead active block stop, it is made not exceed wheel hub wheel rim bead seat hump, thus can remove a tyre smoothly.

A. 17 and baffle structure 16, baffle structure 16 is cam structure, S. A. 17 S. A. is positioned on a face of baffle structure 16, there is helicitic texture 18 on S. A. 17 surface, an end face of S. A. 17 is non-circular end face 19, and there is a groove structure 20 described S. A. 17 and baffle structure 16 intersection; Tire bead active block stop 3 is arranged in the borehole structure 14 of integrated hub 1 by S. A. 17, and rotates centered by the axle center of S. A. 17; By being exposed at the non-circular end face 19 outside integrated hub 1 outside S. A. 17, tire bead active block stop 3 can be regulated to carry out activity along the diametric(al) of integrated hub 1.
As Fig. 2, be provided with sealing member 7 between tire bead active block stop 3 and integrated hub 1, the through hole in the middle of sealing member 7 is through the S. A. 17 of tire bead active block stop 3, and sealing member 7 adopts thermoplastic elastomer or thermo-setting elastomer to make, and plays the effect of sealing; Nut 5 has helicitic texture 18 to coordinate with S. A. 17 surface, is provided with pad 6 between the heavy stand face of nut 5 and heavy stand structure 13; Between baffle structure 16 and tire 2 inwall, be provided with Non-slip material 4, described Non-slip material 4 hardness is less than described baffle structure 16 hardness, and Non-slip material 4 can increase the friction force with tire 2 inwall, and avoids scratching tire 2 inside face.
Mounting tyre tyre bead active block stop 3 in the borehole structure 14 of race 9 sidewall nearest apart from integrated hub 1 wheel rim bead seat.
In tire installation process, first rotating tire's tyre bead active block stop 3, makes it not higher than wheel hub wheel rim bead seat hump 8 (as Fig. 5), ensures that tire 2 is installed smoothly; After the bead seat that tire bead is installed to integrated hub 1, by rotating counterclockwise tire bead active block stop 3 (see Fig. 6), make its baffle structure 16 exceed integrated hub 1 wheel rim bead seat hump 8 and do not exceed the maximum profile of wheel hub (as shown in Figure 1, Figure 2, Fig. 6), stopping that tire 2 tyre bead slips into wheel hub race 9.
