Novel hub for tubeless wheel

Abstract

The invention discloses a novel hub for a tubeless wheel. Annular supporting ribs are arranged between two rims and higher than the rims and provided with technical tire mounting notches, two sides of each annular supporting rib are provided with technical tire mounting grooves, and a tire can be turned across the annular supporting ribs through the technical tire mounting notches and the technical tire mounting grooves to complete tire mounting and demounting operations. The annular supporting ribs are rough in surface and / or provided with a plurality of notches to form sawtooth structures. Therefore, even a vehicle is driven when the tire is flat or insufficient in air pressure, the two rims of the hub can serve as a main support while the annular supporting ribs and a road surface jointly extrude the tire contacting with the ground to form an auxiliary support, slipping of the tire and the novel hub in emergency braking of the vehicle can be prevented, and uncontrollability in braking and steering of the vehicle having the flat tire in running can be prevented. In addition, when the wheel is stressed axially, axial relative movement of the tire and the novel hub can be reduced, and accordingly overturning caused by rim landing resulted from separation of the tire from a bead seat of the novel hub is prevented.

Description

technical field [0001] The invention relates to a safety device, which belongs to the technical field of automobile tire blowout safety control. Background technique [0002] After the tire has no air pressure, the pressure on the contact surface between the tire bead and the inner wall of the wheel rim will disappear. When the wheel is axially stressed, the tire will easily fall off from the bead seat of the wheel hub; When the difference in air pressure between inside and outside disappears, the tire will easily fall off from the bead seat of the wheel hub, causing the rim of the wheel hub to touch the ground, resulting in a rollover accident, which seriously threatens the safety of the driver and passengers.

Problems solved by technology

[0002] After the tire has no air pressure, the pressure on the contact surface between the tire bead and the inner wall of the wheel rim will disappear. When the wheel is axially stressed, the tire will easily fall off from the bead seat of the wheel hub; When the difference in air pressure between inside and outside disappears, the tire will easily fall off from the bead seat of the wheel hub, causing the rim of the wheel hub to touch the ground, resulting in a rollover accident, which seriously threatens the safety of the driver and passengers

[0003] After the tire has no air pressure, the pressure on the contact surface between the tire bead and the inner wall of the wheel rim will disappear, and the friction force between the tire bead and the inner wall of the wheel rim will also disappear, and the friction between the wheel hub and the tire will be greatly reduced. Weakened; once a tire blows out in a high-speed car, the pressure difference between the inside and outside of the tire disappears. At this time, if emergency braking is used, the wheel hub and tire may slip out of sync, which will easily cause braking and steering out of control, seriously threatening the driver and the driver. passenger safety

[0004] At present, most of the technologies on the market are to install some devices between the wheel hub and the tire, which is difficult to install, high in cost, poor in consistency and reliability, and seriously affects the dynamic balance of the wheel; some products require an increase of 2 kg per wheel Above, the weight of the wheels increases greatly, which directly affects the handling of the vehicle. When the vehicle needs to start and stop frequently when driving on urban roads, the fuel consumption will increase significantly.
