Unidirectional coupling device for e.g. bicycle, has bar movable around axle by conjoint actions of spring, centrifugal and inertial forces, and spring coupled to adjusting screw to adjust spring force according to mass of bar
The device has an articulated bar provided between inner and outer driven gears (1, 2) and movable around an axle (11) by conjoint actions of force of a spring (4), a centrifugal force and an inertial force. The spring is coupled to an adjusting screw (14) to adjust the spring force according to a mass of the bar. The bar is engaged in teeth of an internal crown via its tapered part when an engine torque appears on the driven gear.
