Hubs TRIZ Cases

Embedded capacitive fastener sensors and wheel-powered wireless reporting track stud tension in real time to detect yield, under-tension, and over-tightening.

A cellular polyurethane spring preloads freewheel clutch rings more evenly, cutting tooth wear, operating noise, and preload complexity.

Rounded tooth roots and convex hub surfaces reduce shrinkage stress cracks and noise in plastic-rim composite wheels.

A convex hub surface with progressive tooth root diameters reduces stress concentrations, noise, and play in overmolded composite gear wheels.

Annular hub, spacers, platens, and inserts cure a uniform non-pneumatic tire structure that improves load capacity and durability.

A nested dual epicyclic gear train achieves high wheel-drive reduction ratio in the tight space of aircraft landing gear.

A mounting plate, coolant jacket, and air gaps isolate motor heat in an axle assembly while simplifying maintenance and widening vehicle aisles.

Injection-molded fiber-reinforced thermoplastic and Z-shaped spokes help bicycle wheels carry higher loads without excess weight or creep.

A flexible elastomeric wheel seal deflects pressurized water while draining condensate to protect roller bearings from corrosion.

Three motors rotate and steer one wheel on different axes, improving vehicle mobility across varied ground environments.

A three-motor wheel module adds axial drive, radial rotation, and steering to improve vehicle travel across varied ground environments.

A splined connecting crown and elastic ring secure the rear hub freehub while allowing manual removal and lower maintenance cost.

Cancellation electromagnets and a serpentine isolator ring adjust wheel flux to maintain strong ferromagnetic grip while enabling easier release.

A screw-actuated wheel-side coupler disengages the drive shaft without gearbox disassembly, making towing and service access easier.

An angled washer lets one conical bicycle through axle fit varied dropout seats, cutting axle variants, tooling costs, and selection difficulty.

Axially movable outer and inner ratchet wheels reduce bicycle hub tooth wear and extend service life during repeated engagement.

A seal cover shields the in-wheel motor rotation angle sensor from water and dust when bracket deformation creates sealing gaps.

Successive phased pawl engagement spreads drive load across multiple pawls, reducing single-pawl overload and premature bearing failure.

A continuous inner, outer, and connecting weld path secures a bicycle hub lid while limiting welding deformation and complexity.

An offset-axis gear-driven wheel lowers the vehicle center of gravity, improving ASRS travel stability while allowing larger motors.

A detachable shaft-stator connection lets the motor assembly and battery unit be replaced quickly without dismantling the wheel hub.

By combining the wheel rim and pulley in one hub, this wheel assembly cuts interfaces, improves co-axiality, and simplifies service.
