Centrifugal clutch system

摘要

A centrifugal clutch system includes a centrifugal weight, an outer member, an inner member, a first clutch plate, a second clutch plate, a bottom portion side pressure member, and an open side pressure member. The centrifugal weight is movable in a radial direction of the clutch system. The outer member is rotatably supported on a rotation axis and subjected to a driving force. The inner member is integrally and rotatably supported on the rotation axis. The first and second clutch plates are respectively supported in the outer and inner member. The bottom portion side pressure member thrusts each clutch plate to an open side of said outer member and releases the thrusting force by the movement of said centrifugal weight. The open side pressure member thrusts each clutch plate to a bottom portion of said outer member. The open side pressure member is supported on said inner member.

主权项

1. A centrifugal clutch system comprising:
a centrifugal weight movable in an inward radial direction of the clutch system and an outward radial direction of the clutch system; an outer member having an axis coaxial with a rotation axis and having a cylindrical shape with a bottom portion, the outer member being relatively rotatably supported on the rotation axis and being constantly subjected to a driving force from a driving source; an inner member integrally and rotatably supported on the rotation axis in an inner periphery side of said outer member; a first clutch plate integrally and rotatably supported in the inner periphery side of said outer member; a second clutch plate integrally and rotatably supported in an outer periphery side of said inner member; a first pressure member arranged on the inner periphery side and on a bottom portion side of said outer member, said centrifugal weight is sandwiched between said first pressure member and said bottom portion of said outer member such that said centrifugal weight applies a thrusting force to each clutch plate to an open side of said outer member by movement of said centrifugal weight in the outward radial direction and releases the thrusting force by movement of said centrifugal weight in the inward radial direction; a second pressure member arranged on the inner periphery side and on the open side of said outer member and thrusts each clutch plate to said bottom portion side of said outer member when being subjected to the thrusting force from said centrifugal weight, and said second pressure member is supported on said inner member; a move limiting portion configured to limit a movement of said outer member to said bottom portion side in a clutch axial direction; and a thrust bearing arranged between the move limiting portion and said bottom portion of said outer member.
