Deceleration sensor for anti-skid vehicle brakes

摘要

A sensor which directly senses the ratio between wheel and vehicle deceleration, containing a shaft rotating at a velocity proportional to the angular velocity of the vehicle wheel, and a flywheel connected to this shaft by spring means which permit both relative rotation and relative axial motion between flywheel and shaft, with a fixed ratio between the rotation and axial motion. When vehicle brakes are applied, the flywheel moves axially depending on the ratio between wheel and vehicle deceleration, and this motion can be utilized to actuate an anti-skid brake system.
