The invention belongs to the technical field of torque transmission and particularly relates to a lever speed and torque controller based on centrifugal force. The controller comprises a first transmission shaft, a driving disc, an outer ring, centrifugal blocks, a second transmission shaft, an inner disc, belt springs and friction ends. When the first transmission shaft serves as the input power, rotation in any direction can drive the second transmission shaft to rotate, the magnitude of torque capable of being transmitted depends on lever springs and the centrifugal blocks and increases along with increasing of the rotating speed of the second transmission shaft, the torque transmitted to the second transmission shaft from the first transmission shaft is gradually decreased, and finally the second transmission shaft keeps rotating at a constant speed; and when the second transmission shaft serves as the power input shaft, since previously the friction ends and the belt springs have certain friction, small torque can be transmitted to the first transmission shaft, and the two belt springs are not tensioned in the transmitting process, so that only the small torque can be transmitted. The lever speed and torque controller based on the centrifugal force has good application prospects.
