ABSTRACT:
The disclosure herein is concerned with an automatic transmission in which rotation of an input shaft engages a first centrifugal clutch assembly which, in turn, drives reduction planetary gears and, as the input speed picks up, a second centrifugal clutch assembly comes into play whereby the entire system between the input and output shafts rotates as a unit. The clutch assembly consists of an extensible roller bearing provided with a series of circumferentially spaced openings in which are received roller weights arranged in pair and in contacting engagement with adjacent surfaces of pressure discs which, together with co-acting clutch discs, also form part of the clutch assembly. In one embodiment of the invention, the planetary gear assembly is located between the first and second centrifugal clutch assembly; in a second embodiment, the second centrifugal clutch assembly is located between the first centrifugal clutch assembly and the planetary gear assembly; and in a third embodiment, the location of the planetary gear assembly is similar to that of the second embodiment, but only one extensible roller bearing is used for the engagement of both centrifugal clutch assemblies.
