Problems solved by technology

[0004] The above-mentioned two-way clutch has the following disadvantages: one is that the torque output direction can only be changed through the relative rotation direction of the inner ring or the outer ring, that is, program controllability cannot be realized; When the inner ring is the active part, the clutch is in a two-way overrunning state. This feature is not suitable for the conditions of use of automobiles, equipment, etc., and the versatility is poor.

Abstract

The invention discloses a controlled wedge block type bidirectional overrunning clutch. The controlled wedge block type bidirectional overrunning clutch comprises an outer ring, an inner ring, a plurality of anticlockwise wedge blocks located between the outer ring and the inner ring, a plurality of clockwise wedge blocks located between the outer ring and the inner ring, a holder which is located between the outer ring and the inner ring and used for holding the anticlockwise wedge blocks and the clockwise wedge blocks, and a control panel used for controlling the anticlockwise wedge blocks and the clockwise wedge blocks to rotate. Each wedge block in the anticlockwise wedge blocks and the clockwise wedge blocks is provided with a first working face and a second working face. The first working faces of the anticlockwise wedge blocks and the first working faces of the clockwise wedge blocks make contact with the working face of the outer ring permanently, and the second working faces of the anticlockwise wedge blocks and the second working faces of the clockwise wedge blocks can make contact with or leave the working face of the inner ring through rotation of the control panel. The overrunning clutch disclosed by the invention is good in universality and controllable in program.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a controllable sprag type two-way overrunning clutch. Background technique [0002] An overrunning clutch, also known as a one-way clutch or a one-way bearing, is a device that can transmit torque in a single direction of rotation. Overrunning clutch is to use the speed change of the main and driven parts or the transformation of the rotation direction to realize automatic clutching. Existing overrunning clutches mainly include several forms of roller type, wedge type, meshing type, ratchet type and chain ring type. Among them, the wedge type overrunning clutch is a kind of clutch that uses the opposite sex wedge as the wedge, and uses the wedge to form a friction pair with the inner and outer rings. The inner ring, the outer ring and the wedges squeeze each other to increase the frictional force to achieve the state of no relative movement, the same direction o...
