Disc Wheels TRIZ Cases

Movable locking levers engage a hub abutment surface to stop accidental unscrewing while still allowing quick wheel removal with a release tool.

A spring-biased locking lever engages the hub axially to stop torque-driven wheel loosening while keeping wheel changes simple.

Movable locking levers engage a hub abutment surface to stop accidental wheel loosening under torque while allowing easy wheel removal.

A reinforced double-layer support wheel resists lateral and vertical loads, enabling safer transport of stranded vehicles without excess weight.

A rotating hook-shaped anti-slip member built into the wheel adds on-demand traction on snowy or icy roads without separate snow chain installation.

A bearing-based hub adapter lets wheels rotate independently of locked brakes or damaged axles, so immobile vehicles can be moved.

Axially offset window-forming flanges cut wheel disk blank size and weight while preserving rigidity and brake clearance.

Spaced aperture protrusions create one interface that transmits torque and supports bearing loads while improving modular fit with varied insert shapes.

Projecting hub centering elements and wheel centering pins stabilize thin spacer discs, compensating tolerances and preventing play.

Ventilation holes and locally reduced thickness cut wheel disc mass by 15% while preserving strength and load capacity.

A bell, axle adapter, and retainer keep a wheel attached during bearing or lug failure, preventing dangerous wheel departure at speed.

Radial aperture protrusions let one insert interface handle torque transfer and bearing support while simplifying axle compatibility.

A segmented hole layout lets one adaptor fit a six-lug hub to two five-lug patterns while improving connection security and reducing offset.

Outboard vents and openings between wheel registers and spokes extract heated brake air, improving cooling during hard driving.

Retaining lips or seals at wheel disc insert openings block gravel entry, reducing surface damage, corrosion risk, and difficult removal.

A converter hub and plate retrofit lets mobile home axles use closed-rim, highway-rated wheels without full hub replacement, cutting cost and labor.

A fabricated double-web idler wheel cuts weight and simplifies manufacturing while maintaining strength and distributing tracked-machine loads.

A segmented wheel adaptor uses multiple hole patterns and six bolts to fit a six-lug hub to a multi-wheel while reducing offset and improving stability.

A relieved hub surface cuts wheel mass while improving axle alignment and easing installation, removal, and service on heavy-duty vehicles.

Removable aerodynamic inserts with blades manage airflow through structural wheel openings to reduce drag.

Frustoconical geometry reduces fixture noise by 70-80% in the 100-210 Hz range, eliminating data skew from resonance.
