Hubs TRIZ Cases

Independent lever positioning eliminates iterative clamping cycles, ensuring consistent force and reliable operation across varying temperatures.

True-paired spokes attach to a radial rim flange, reducing side wobble forces while maintaining rim strength.

An expanded region on a solid polyurethane tire increases the contact patch to maintain balance on uneven terrain without adding excessive weight.

A bicycle wheel uses oversized spokes that rotate within hub recesses to support the rim concentrically without extra securing hardware.

A bicycle dropout assembly incorporates a rotational control mechanism with a nut and cover to orient the quick release handle.

Merges sealing and alignment functions into one hubcap, eliminating lost gaskets and misaligned auxiliary devices.

Pre-assembled axle bearings and dust shields reduce manufacturing complexity by eliminating in-situ bearing installation steps.

A yieldable engagement interface retains a control shaft within an axle sleeve while allowing axial withdrawal for servicing.

Forging the outer chamfer directly eliminates machining steps, reducing production time and preventing burrs during brake disk assembly.

Labyrinth seals formed by an L-shaped channel and intermediate fold reduce friction and bulk while maintaining sealing efficiency.

A self-contained electric wheel system uses an integrated motor and battery to propel disabled vehicles remotely, eliminating tow truck wait times.

Offset roller rows reduce scrubbing wear and increase load capacity compared to tapered omni-directional wheels.

A ceiling-mounted hub lifting system uses vertical plates and automated reels to handle heavy automotive components.

A rotary apparatus knife cuts debris in the clearance passage to protect the face seal.

Relocating the seal groove to the outer race cylinder surface reduces radial size while maintaining axial length and sealing reliability.

Torque sensing arrangement integrated into the outer freehub member detects torsional strain to measure power transmission through the rear hub assembly.

A flexible polyurethane cable merges wheel speed sensor wiring with a breather line into one assembly.

A vehicle wheel hub with two ports channels pressurized fluid to expel lubricant from the internal chamber, eliminating messy grease leakage during maintenance.

A preload adjustment tool mounts on threaded axles to set bearing assembly loads and align lock nut guide marks.

Segmented hub structures enable larger transmission components within fixed outer diameters.

An in-wheel motor drive device repositions components above the hub bearing to align the steering axis with the wheel center.

A steel-aluminum composite hub uses interference-fit steel inserts to reinforce the lightweight aluminum base body.

A roller bearing cover uses a stepped surface and inscribing geometry to form an annular space filled with sealant.

A tubular sleeve with conically shaped barbs secures within a wheel aperture to provide an interference fit.
