Abstract
The present invention relates to an unpowered braking device using centrifugal force. The present invention may comprise: a housing; a brake drum installed inside the housing; a plurality of braking links rotatably installed on a rotating shaft of the housing and connected such that both ends thereof can expand and contract by means of centrifugal force; brake rollers provided on both ends of the braking links, respectively, such that, when the braking links expand, the brake rollers are forced against the inner walls of the brake drums and thereby generate braking force/torque; and an elastic member for providing elastic force such that both ends of the braking links, which have expanded, can contract.
Claims9
A non-powered passive braking device using a centrifugal force, comprising:
- a housing;
- a brake drum mounted in the housing;
- a plurality of brake links rotatably mounted on a rotating shaft of the housing and connected with each other so that both ends thereof are expanded or contracted by centrifugal force;
- brake rollers provided at both ends of the brake links and, when the brake links are expanded, coming into close contact with an inner wall of the brake drum so as to generate a braking force;
- an elastic member configured to provide an elastic force so that expanded ends of the brake links are contracted;
- a central member rotatably mounted on the rotating shaft of the housing;
- and
- brake plates respectively mounted at a front surface and a rear surface of the central member, wherein the brake rollers are rotatably provided between both ends of the brake plates.
