Racing Wheel Beadlock-Liner Structure for Tire Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing racing wheels, particularly beadlock and liner wheels, lack the combination of secure tire attachment, stability, and precise air pressure control necessary for high-performance motor racing, often adding unnecessary weight and compromising safety and speed.
Innovation Solution
A wheel design that integrates wider rim projections for both beadlock and liner functions, incorporating an inner tire for enhanced stability and a channel for direct air inflation, along with knurls for secure tire engagement, to improve safety, stability, and speed while maintaining lightweight performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a beadlock wheel design is used to secure the tire firmly, then tire attachment reliability is improved, but the wheel lacks stability and shape control
Solution Approach 1:
The patent combines the beadlock wheel design and liner wheel design into a single integrated system. The wheel includes both beadlock rings for securing the outer tire and an inner tire (liner) for providing stability and shape, merging the advantages of both designs while eliminating their individual limitations.
Solution Approach 2:
The wheel structure serves multiple functions simultaneously: the beadlock rings provide secure tire attachment, the inner tire provides stability and shape control, and the wide rim projections accommodate both beadlock rings and inner tire. This multi-functionality resolves the contradiction by making the wheel system capable of both secure attachment and stability.
2Stability of the object's composition
If an inner tire is added to provide stability and shape, then tire stability is improved, but the wheel weight increases
Solution Approach 1:
The inner tire is designed to provide just enough stability and shape control without excessive weight. The beadlock rings are positioned to secure the outer tire with minimal additional weight, providing sufficient attachment reliability without over-engineering the system.
3Reliability
If wider rim projections are used to accommodate both beadlock and liner functions, then tire attachment reliability is improved, but the wheel weight increases
Solution Approach 1:
The wide rim projections serve multiple functions: they accommodate the beadlock rings for secure attachment and simultaneously provide support for the inner tire. This multi-functionality justifies the additional weight by delivering multiple benefits from a single structural feature.
Solution Approach 2:
The rim projection structure is designed to combine the requirements of both beadlock attachment and inner tire support into a single integrated feature, eliminating the need for separate structures and minimizing the weight penalty.
4Ease of operation
If the inner tire seals directly against the outer tire, then air pressure control is simplified, but the seal reliability decreases
Solution Approach 1:
The inner tire seals against the wheel rim rather than directly against the outer tire, creating an intermediary sealing surface. This intermediary approach provides a more reliable seal by eliminating direct contact between the two tires, while the separate inflation system maintains ease of operation.

AI summary
A wheel is provided that combines the principles of a beadlock wheel and a liner wheel for improved performance in motor racing, in particular drag racing. The wheel has beadlock rings that fasten to inner and outer rims of the wheel to secure an outer tire, and the wheel has knurls interior to the inner and outer rims to secure an inner tire. Projections from the inner and outer rims are arranged to accommodate the various functions of the combination of the beadlock rings and the inner tire. The projections counterintuitively add weight to the wheel, yet the combination of beadlock rings and an inner tire results in improved stability and safety as well as faster times on the racetrack.
