WIPO Patent Application WO/2009/074034
Kind Code:
A1
Abstract:
An automatic clutch for motorcycle includes a front disc (1), a back disc (2) and a middle disc (3). The left end of the middle disc (3) is in wall shape and forms a cavity together with the wall of the back disc (2) to restrict the axial displacement of a driven disc (4) arranged at the left side. An abdominal cavity of the middle disc (3) is coaxially and uniformly hinged with two to six fly hammers (5). A hammer handle is arranged at the left part of the fly hammer (5) and a hammer body is arranged at the right part. The left end of the hammer handle is provided with a pivoting hole which is hinged on the hinge base at the middle part of the left side of the middle disc (3). The left side of the right part hammer body is provided with pressing finger (7) pressed at right end of a clutch pressure plate. In the cavity of the right part hammer body there is a return piston (8) and a return piston spring (9). The spherical top end of the return piston (8) reciprocates on an orbit on a cavity wall of an inner hole of the middle disc (3). The high-speed centrifugal force of an engine leads a fly hammer group to be pressed a clutch membrane group (13) in the back disc (2), so as to transmit power to an output disc connected with a gearbox.
