Abstract
An improved planetary traction drive mechanism for use in actuating a throttle valve assembly is provided. An electric drive motor supports a cup-shaped member defining the outer ring of the mechanism. The drive shaft of the motor extends into the cup-shaped member to define a sun roller and forming an annular space between the sun roller and the outer ring. An output plate is rotatably supported on the drive shaft, and one or more deformable planetary friction rollers are disposed in radial compression between the outer ring and the sun roller are mounted on the plate. An output shaft extends from the plate and may or may not be coaxially aligned with the sun roller. The output shaft may be connected via a link to a lever arm on the throttle shaft of the throttle valve, which may be used on an internal combustion engine.
