摘要： An automatic transmission including an input shaft connected to an output shaft of an engine. A first clutch of a first planetary gear unit is positioned between the input and first output shafts while a third clutch of a third planetary gear unit is interposed between the second and third output shafts. Each of the first and third clutches are engaged by the action of flyweights operated by centrifugal force and disengaged by thrust exerted on helical gears of the planetary gear units. A second planetary gear unit includes a second clutch interposed between the first and the second output shafts. Control means control the second clutch so as to engage the first and the second output shaft or disengage the first and the second output shafts from each other and provide smooth shockless upshifting and downshifting of the automatic transmission.

摘要： A centrifugal friction clutch for an automatic transmission includes axially movable friction elements supported on and rotated with an input member. Axially slidable clutch elements are supported on a clutch cover, wherein centrifugal weights held by spring members are disposed at predetermined positions on the clutch cover. First retaining means on the clutch cover press the friction members and clutch members against each other so that power can be transmitted when the centrifugal weights are displaced. A first spring bearing member contacting one end of each of the spring members urges the centrifugal weights toward their initial positions while a second spring bearing member contacting the other end of each of the spring members is held in place on the clutch cover by second retaining means engaging the clutch cover. The first and second bearing members are axially movable relative to the input member.
