Abstract
A mechanical torque transmitting apparatus such as a one-way clutch which includes two distinct sets of flexural arms (primary and auxiliary) and a cylindrical engagement surface. The primary flexural arm is adapted to be in edgewise continuous engagement with the cylindrical surface. Preferably, the primary flexural arm has a long, straight, narrow cross-section area and applies a relatively low force against the cylindrical surface when said surface is rotating in a free-wheeling direction. In the non free-wheeling direction, the force against the cylindrical surface increases until the rotational forces overcome and buckle the primary flexural arm whereupon the auxiliary flexural arm is brought into contact with the cylindrical surface to resist further rotation.
