Title:
二輪車にジャイロを用いて安定をもたらすためのシステム及び方法
Document Type and Number:
Japanese Patent JP2009500221
Kind Code:
A
Abstract:
This invention provides a stabilizing system and method for two-wheeled vehicles (typically small, human-powered bicycles) that affords the rider no restriction on the full range of movements (banks, leans, etc.) common to bicycles, but that provides greater stability during turns and other maneuvers so that an unintentional bank or tilt (potentially causing a fall) is less likely, even at relatively slow speeds and startup. A rotating mass of predetermined mass-value and radial mass-distribution is provided coaxially with the front axle. The mass is supported on bearings so as to freewheel with respect to the rotation of the front wheel. As such it can be induced to spin significantly faster than the front wheel thereby generating a gyroscopic effect at the front wheel about the axle. This gyroscopic effect influences the steering of the wheel by the rider. Due to precession, the wheel tends to follow any excessive bank by the bicycle, ensuring that the rider can "steer-out-of" an unintended tilt or bank. Likewise, the gyroscopic effect limits the rider's ability to execute excessive steering, thereby preventing jackknife movements.
