Safety Hub Toothed Collar for Tire Bead Retention After Blowout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hubs allow tire beads to detach during a burst, leading to loss of synchronous rotation and significant deviation of the automobile, increasing the risk of accidents during high-speed travel.
Innovation Solution
A safety hub with an anti-detachment collar featuring a toothed structure that locks the tire bead, allowing it to continue rotating with the hub, reducing the difference in rotation travel distance between wheels and maintaining vehicle direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional hub with a small-diameter groove is used to allow tire mounting, then the tire can be mounted on the hub, but the tire bead detaches inwardly during a burst, causing loss of synchronous rotation and significant vehicle deviation
Solution Approach 1:
The hub structure is segmented into multiple functional zones: the outer groove for tire mounting and the inner anti-detachment collar with toothed structure for bead retention. This segmentation allows the hub to simultaneously provide easy tire mounting while preventing bead detachment during bursts, resolving the contradiction between ease of manufacture and reliability
Solution Approach 2:
The anti-detachment collar acts as an intermediary structure between the tire bead and the hub body. During normal operation, it remains passive, but during a burst, it actively engages with the tire bead through its toothed structure to prevent inward detachment, thus maintaining synchronous rotation without interfering with the mounting process
2Ease of manufacture
If the hub groove diameter is made smaller to facilitate tire mounting, then mounting is easier, but the traveling distance difference between burst and non-burst sides increases, causing greater vehicle deviation
Solution Approach 1:
The hub is divided into functional segments with the anti-detachment collar positioned closer to the wheel flange than the outer groove. This segmentation creates distinct zones: the outer groove for mounting and the inner collar for stability maintenance, allowing small groove diameter for easy mounting while the collar prevents excessive deviation by retaining the bead
Solution Approach 2:
The anti-detachment collar with its toothed structure is pre-configured in the hub design to engage with the tire bead before a burst occurs. This preliminary arrangement ensures that when a burst happens, the bead is already positioned to be retained by the collar, preventing the instability that would otherwise result from the small groove diameter

AI summary
A safety hub against tire bursts is provided according to the present application, which includes a hub body. The hub body includes an outer annular surface, a first side surface, and a second side surface. The first side surface and the second side surface are oppositely arranged on two sides of the outer annular surface. The two sides of the outer annular surface are oppositely provided with a first wheel flange and a second wheel flange. A tire mounting seat is formed between the first wheel flange and the second wheel flange, and an anti-detachment collar is provided on the tire mounting seat. The anti-detachment collar is an annular protruding ring arranged along the outer annular surface. The anti-detachment collar is concentric with the outer annular surface. The surface of the anti-detachment collar is provided with a toothed structure which includes multiple protruding teeth and recesses. The protruding teeth and the recesses are alternately arranged. The protruding teeth are protrusions extending outward from the surface of the anti-detachment collar. The recesses are grooves recessed inward from the surface of the anti-detachment collar. The overall diameter of the protruding teeth is greater than the diameter of a tire bead adapted to the tire mounting seat. If the tire with the safety hub against tire bursts bursts, the anti-detachment collar can lock the tire and support the tire bead simultaneously, so that the burst tire can continue to rotate with the hub, thereby reducing the amplitude of deviation of the automobile.
