ABSTRACT:
In a gear type transmission, a pair of gears are provided on input and output shafts always in mesh with each other with one gear being fixedly mounted on the input or output shaft and the other gear being rotatably mounted on the other shaft. A synchronizer for synchronizing the two gears comprises an inner cone which has a tapered outer surface and is rotatably fitted on a hub portion formed integrally and coaxially with the other gear and is in engagement with the clutch hub to permit rotation of the inner cone relative to the clutch hub by a predetermined amount, an outer cone which has a tapered inner surface opposed to the tapered outer surface of the inner cone, and is adapted to be engaged with said hub sleeve by way of splines to be rotated together therewith when the hub sleeve is slid into engagement with the gear spline, a double cone which is disposed between the inner surface of the outer cone and the outer surface of the inner cone and is supported for rotation together with the other gear and for sliding movement in the axial direction of the gear, and a synchronizer key which is movable in response to the sliding motion of the hub sleeve to move the outer cone in the axial direction of the clutch hub to bring the outer cone into frictional engagement with the double cone, thereby bringing the double cone into frictional engagement with the inner cone.
