Abstract
Disclosed is a centrifugal type clutch brake device in which a ring-like drive disc is caused to move vertically in synchronism with the engagement/disengagement of a centrifugal clutch to thereby engage/disengage the brake, thus attaining a simplification in structure. In the centrifugal type clutch brake device of the present invention, the ring-like drive disc (11) is connected to the lower portion of a centrifugal clutch housing (21) of a centrifugal clutch (22) through the intermediation of a moving device (30), and the brake is engaged/disengaged in synchronism with engagement/disengagement of the centrifugal clutch (22).
Claims4
A centrifugal type clutch brake device comprising:
- a centrifugal clutch shoe fixed to a rotation shaft;
- a driving means for rotatably driving the rotation shaft;
- a centrifugal clutch housing rotatably provided on the rotation shaft through the intermediation of a bearing and forming a centrifugal clutch with the centrifugal clutch shoe;
- a ring-like drive disc provided at an end of the centrifugal clutch housing through the intermediation of a moving means so as to be axial movable;
- a driven member connected to the ring-like drive disc;
- and
- first and second braking frictional members provided on both sides of a stationary plate provided on a driving means side of the ring-like drive disc and capable of coming into contact with the centrifugal clutch housing and the ring-like drive disc, respectively,
- wherein, when, in a state in which the centrifugal clutch is engaged to cause the ring-like drive disc to be rotated through the moving means, a rotating speed of the rotation shaft is reduced and the centrifugal clutch is disengaged to cause the ring-like drive disc to rotate faster than the centrifugal clutch housing, the ring-like drive disc moves towards the centrifugal clutch housing through the moving means, and the ring-like drive disc comes into sliding contact with the second braking frictional member to stop rotating.
