摘要： A dog clutch mechanism includes a case, first and second rotatable shafts rotatably disposed coaxially in the case, the second rotatable shaft having an annular groove defined in an outer periphery thereof, a dog piece fixedly mounted on the first rotatable shaft and having first dog teeth confronting an end of the second rotatable shaft, a hub axially slidably mounted on the second rotatable shaft and having second dog teeth meshingly engageable with the first dog teeth, the second dog teeth being movable out of meshing engagement with the first dog teeth under a thrust force in response to relative torque transmission between the first and second rotatable shafts. The hub has guide holes extending radially therethrough toward the second rotatable shaft and a plurality of balls are retained respectively in the guide holes are and engageable in the annular groove. A sleeve is axially slidably disposed on an outer periphery of the hub for engaging the balls and pressing the balls into at least the annular groove.

摘要： An electronically controlled transmission in which a shift actuator for driving a sleeve of a roller synchro mechanism and a throttle actuator for an engine are electronically controlled. The shift actuator is comprised of a drum type actuator of a simple structure comprising a shift drum and a shift fork. The use of the roller synchro mechanism ensures that only a small driving force for the shift drum is required, which makes it possible to provide a reduction in size of the shift actuator. In addition, a shift lever for operating a shift switch for producing the shifting instruction signal is mounted on either left or right side of the steering wheel. This ensures that the shifting-up and shifting-down signals can be produced by one of the driver's hands, leading to an improvement in operability of the shift lever.

摘要： A retainer retaining a plurality of rollers therein so as to permit their slight movement in a radial direction is disposed between cam grooves provided on the outer periphery of an inner cam secured to a rotary shaft and a roller abutment surface formed on the inner periphery of a gear relatively rotatably carried on the rotary shaft, and a dowel-admission groove is defined in a side of the retainer. A dowel provided in a sleeve can enter the dowel-admission groove. The groove is defined between the adjacent rollers retained in the retainer, or at least part of the inner cam, the rollers and the retainer are disposed in a recess made in the gear, thereby achieving a reduction in axial dimension of a roller synchro mechanism. In addition, the retainer is comprised of two components: a body portion and a cover plate, thereby facilitating their machining, and a slide contact portion is formed on the outer periphery of the body portion and is tightly fitted to the roller abutment surface of the gear, so that the retainer may be dragged by the gear, thereby providing a prompt engagement of the rotary shaft with the gear.
