Benefits to Shweel™
Physics
The hub mostly leads the rim.
Its torque then assists rolling.
Higher contact-to-rolling
radius-ratio adds stability.
Hex and Square shweel movies
The hinges are approaching-and-
separating each other.
The shocks incline back-and-forth,
forming arrow heads pointing out
the hub offset.
All shocks complete on full stroke per wheel revolution phased off each other.
Dynamics
• Independent engineering of vertical, lateral and torsional stiffnesses
• Progressively cushioned static and dynamic wheel forces
• Flexible drive train coupler prevents vehicle slipping
• Higher rotational inertia adds robustness
• Rolling assistance reduces, cancels or reverses rolling resistance
• Lower vehicular center of mass adds overturning stability
• Higher static and dynamic load capacity
• Zero unsprung mass isolates the impacts and vibrations of the ride
Vibrations
Large inflated tire deflections sets up strong vehicular vibrations.
Large shock absorber strokes sets up weak vehicular vibrations.
Losses
Shocks design can reduce, and hub-offset forcing can eliminate drag on towing.
Security
Bullet/explosion/spike proof. Cushioned soft ride, with hard strong cornering.
Agriculture
• It saves 8% fuel and emissions.
• It does not slip on ice and snow.
• It does not dig in sand and mud.
It does not sink in rice-fields and mud.
