ABSTRACT:
A synchronizing apparatus for a power transmission comprises a shaft for rotation in response to a power source, a clutch hub fixed to the shaft for rotation therewith, the hub including an outer spline thereon; a sleeve including an inner spline for engaging the outer spline of the clutch hub, and having an inner frictional face radially outward from the inner spline; a gear rotatably mounted on the shaft including an outer spline surface having first and second grooves therein, and a circular groove between the first and second grooves; the spline surface also having a pair of adjoining sloped portions thereon, each having a different degree of slope; a synchronizing ring including an outer frictional surface for frictional contact with the inner frictional face, and an inner projection for engaging the outer spline surface of the gear and; a spring mounted in the circular groove for movement along the two sloped portions of the outer spline surface for biasing the ring toward the sleeve.
