Transmission synchronizer
This patent describe a synchronizer for a gear type transmission in which a pair of gears are provided on input and output shafts. The two gears of each pair are always in mesh with each other with one gear of each pair being fixedly connected to one of the input and output shafts and the other gear of each pair being rotatably connected to the other shaft to be rotatable relative thereto, and the other gear of each couple is adapted to be drivingly connected to the other shaft by way of a clutch hub with a radially extending disc portion and an axially extending boss portion fixedly provided on the other shaft, a gear spline provided on the other gear of each couple integrally therewith, and a hub sleeve which is engaged with the clutch hub to be rotated together therewith and is slidable in the axial direction of the clutch hub to be engaged with the gear spline to transmit rotation of the clutch hub to the gear spline, the synchronizer being for synchronizing the two gears of at least one of the pairs and comprising an inner cone which has a tapered outer surface and is rotatably mounted on a hub portion formed integrally and coaxially with the other gear of the couple 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 ha a tapered inner surface opposed to the tapered outer surface of the inner cone, and is adapted to be engaged with the hub sleeve by way of splines to be rotated together therewith when the hub sleeve is slid into engagement with the gear spline.
