ABSTRACT:
A drive assembly particularly suited for washing machines includes a varie speed motor having a motor shaft rotatably supported in two motor housing flanges and a planetary gearing with a sun gear provided on the motor shaft and with a ring gear arranged on an adjacent motor housing flange. A carrier gear of the planetary gearing is separately rotatably supported on a hollow shaft coaxial with the motor shaft and rotatably supported thereon with the hollow shaft being coupled in fixed driving engagement with a driven member of the assembly. The driven member may be driven for high speed operation directly by the motor shaft through a centrifugal friction clutch operatively coupled therebetween. Low speed drive occurs from the motor shaft through the planetary gearing, the overrunning clutch and the hollow shaft and when a certain minimum speed is reached the centrifugal clutch engages causing the driven member to drive the hollow shaft and thereby effect disengagement of the overrunning clutch.
