Abstract

The present invention provides a centrifugal clutch capable of preveting vibration of a cluth housing and effectively preventing ccurrence of abnormal sound. This centrifugal clutch is composed of the clutch housing 12 composed of a circular cylindrical part 12a whose inner face becomes a slide-contact face and a bottom plate part 12b covering one end part of the circular cylindrical part, a rotary shaft which has the same axis as the circular cylindrical part of the clutch housing and to which rotation force is transmitted by the clutch housing, a centrifugal shoe for connecting with the clutch housing 12 or disconnecting from it by rotating around the rotary shaft and coming into contact with or leaving the slide-contact face, and a vibration control cover 17 put on an outer side of the circular cylindrical part. The clutch housing 12 and the vibration control cover 17 have contact parts 30, 40 coming into contact mutually, a non-contact part 50 not in contact, and positioning marks 14, 22 for positioning the clutch housing 12 and the vibration control cover 17 at predetermined relative positions for preventing occurrence of abnormal sound.

Description

technical field [0001] The invention relates to a centrifugal clutch and an assembly method thereof. Background technique [0002] A centrifugal clutch equipped with a motorcycle, etc. is composed of the following parts: a cylindrical part whose inner surface is a sliding surface; a bowl-shaped clutch case composed of a bottom plate part covering one end of the cylindrical part; and a cylindrical part coaxial with the clutch case and a rotating shaft to which torque is transmitted from the clutch housing; and a centrifugal shoe that engages or separates from the clutch housing when contacting or separating from the sliding surface due to the rotation of the rotating shaft. [0003] Such clutches often produce uncomfortable noises as the clutch engages and disengages. One of the causes is the vibration of the cylindrical portion of the clutch housing. [0004] Figure 6 (A) and Figure 6 (B) is a schematic perspective view showing clutch housing vibration. [0005] Circle ...
