Safety hub for lock tire assembly of tubeless tire wheel

Abstract

A safety hub (10) with a lock tire assembly comprises a plurality of coupled and telescopic tire edge lock blocks (11) or retainer rings (40), wherein the tire edge lock blocks (11) or retainer rings (40) are annularly and uniformly distributed in the circumferential direction and arranged between a bead seat (18) and a groove bottom (21). The hub (10) further comprises a corresponding lock transmission device (12) for simultaneously locking and unlocking all the tire edge lock blocks (11) or retainer rings (40). The lock transmission device in the locked state is used for preventing a tire bead (22) from slipping to a groove bottom (21) and separating from the hub (10) and for preventing a wheel flange (20) from touching the ground due to drag force exerted to the tire after the tire burst, and in the unlocked state is used for conveniently changing the tire. The safety hub (10) is mainly used for preventing a vehicle from losing control when the tubeless tire is punctured or loses pressure severely, and can enable the flat tire to keep synchronous with the hub even after the tire loses pressure, thereby giving the same drive force, pull force, steering force and brake force to the wheel, ensuring the normal operation of the vehicle, and avoiding the occurring of accidents.

Description

technical field [0001] The invention relates to a manufacturing method of a wheel hub, in particular to a safety wheel hub used for a tubeless tire wheel belt lock assembly. Background technique [0002] In many traffic accidents, tire blowout accidents account for as high as 5%. Car crashes and fatalities caused by sudden tire blowouts during high-speed driving rank first in the list of expressway accidents, accounting for 49.81% of the death toll in expressway accidents, 63.94% of the injured, and 43.38% of the direct property losses. Blowout accidents occur frequently, and the death rate is high, seriously threatening the safety of life and property of drivers and passengers. [0003] Ordinary wheel hubs usually have bead seats on both sides of the rim. Under the action of air pressure in vacuum tires, the beads on both sides of the tire are tightly set on the bead seats, and will not fall out under the obstruction of the rim. A wheel groove is set in the middle of the...

AI Technical Summary

Problems solved by technology

After the wheel hub loses support on the sidewall, it sinks and directly contacts the road surface. At this time, the wheel loses grip and braking force, which leads to serious sideslip and rollover of the vehicle out of control.

[0005] The existing technologies for preventing and solving tire blowouts are mainly divided into three types: one is to help car owners prevent the occurrence of tire blowouts by means of "tire pressure warning". There are many kinds, and the effect of only starting from the tire pressure is limited

In addition, technologies such as electronic auxiliary braking and direction locking derived from the tire pressure warning device are difficult to implement, poor in reliability, and high in cost.

The second is the "run-flat tire" technology that reinforces the tire wall, but this method is at the expense of the tire's shock absorption function and driving comfort, and the cost is high

Moreover, after installing such a device, the disassembly and assembly of tires is complicated, and it is difficult for non-professionals to master the correct method of disassembly and assembly, which will cause trouble for users in daily use and maintenance, and cannot be widely promoted
