Document Type and Number:
Japanese Patent JPS5833415
Kind Code:
B2
Abstract:
A synchronizing device for change-speed gears including a gearshift sleeve carrier mounted for rotation with a driven shaft and a gearshift sleeve axially slidable via a gear-tooth system over a corresponding gear-tooth system on the sleeve carrier to respective positions in engagement with clutch bodies of a gear to be shifted. In order to prevent unintentional disengagement of the gearshift sleeve from an engaged position interlocking the sleeve carrier and the clutch body, the interface of the gear-teeth at the sleeve carrier and the sleeve are geometrically configured to effectively bias or force the sleeve into the engaged position. In preferred embodiments, the engagement angle of the gearshift sleeve gear-tooth system is different than the engagement of the sleeve carrier gear system and the sleeve carrier gear-tooth system is chamfered by a predetermined angle at the edge thereof which is in contact when a sleeve is axially positioned so as to engage a clutch body on a gear freely rotatably mounted around the shaft which carries the sleeve carrier. In particularly preferred embodiments, the engagement angle of the gearshift sleeve is approximately 20 DEG and the engagement angle of the gearshift sleeve carrier is approximately 15 DEG , whereby, when the sleeve is in an engaged position, the engagement surfaces of the sleeve carrier and sleeve are such as to bias the sleeve toward the engaged position.
