Class Information
Number: 280/5.5
Name: Land vehicles > Suspension modification enacted during travel (i.e., active suspension control)
Description: Vehicle comprising a regulatable elastic means intermediate a vehicle body, chassis, or frame and ground engaging means thereof for supporting the weight of the vehicle body, chassis, or frame (i.e., sprung mass) upon the ground engaging means (e.g., axle, runner, ski, skid, sled, tire, unsprung mass, wheel, wheel assembly, wheel carrier) wherein the regulatable elastic means is caused to alter its elasticity property responsive to a force encountered while the vehicle is in surface traversing motion to control a handling or ride posture characteristic of the vehicle.
