Title:
BRAKE SYSTEM FOR LINEARLY MOVABLE BODIES
Document Type and Number:
WIPO Patent Application WO/1996/023979
Kind Code:
A1
Abstract:
A brake system for linearly movable bodies, comprising a brake member with a bore for receiving a rod in a clearance fit, wherein the brake member is tilted to generate a moment, whereby a brake is applied to a relatively moving rod. The brake member is tiltable on a fulcrum positioned away from the axis of the rod, and recesses which is narrower than the diameter of the bore are formed in the symmetrical portions of the interior of the bore which are in a plane including the fulcrum and the axis of the rod. In this brake system, a torque (moment) is applied to the brake member to cause resistance to occur in the rod-engaging surface of the bore, and a frictional force based on this resistance is used as a braking force, a frictional force based on the resistance of the rod-engaging surface being used as a reaction against the torque. Accordingly, a reaction parallel to the moment does not substantially occur but a large reaction perpendicular to the moment occurs. Since the reaction perpendicular to the moment increases with the thrust, a large resistance is generated by a small moment, and a large braking force occurs with respect to the rod, whereby the brake system and rod are locked.
