    摘要： A synchronizer of the pin type employing a friction cone on the gear to be engaged. The synchronizing ring employs pins positively drivingly engaging an axially movable dogged shifting clutch splined to the output shaft and axially engageable with the gear to be engaged. In one embodiment, the synchronizer ring has a plurality of sprag members circumferentially spaced about the ring and pivoted thereon with the radially outer surface thereof tapered to frictionally engage the friction cone upon axial force application to the ring by the shifting clutch. In another embodiment the synchronizer ring has a plurality of sprag members circumferentially spaced within the ring and pivoted thereon with the radially inner surface thereon tapered to frictionally engage the friction cone upon axial force application to the ring by the shifting clutch. In both embodiments, the sprag members are pivoted by the camming action to increase the friction forces and effect synchronization without increase in the axial force applied to the ring.

    摘要： An improved change gear system having a plurality of spaced countershafts having parallel axes and means supporting the countershafts in a casing for rotation. Countershaft gears are provided on the countershafts and are concentric and rotatable therewith. A rotatable main shaft is provided which is arranged substantially parallel with the countershafts and is preferably located between a pair of the countershafts. Means are provided for pivotally supporting one end of the main shaft in addition to means for guiding the other end thereof in a free floating relation relative to the one end for movement in at least a direction transverse of a plane through the axes of two of the countershafts. A plurality of axially constrained thrust rings are fixed to the main shaft for rotation therewith and cooperate with a fixed thrust plate for transferring thrust loads on the main shaft to the casing. Clutching means are provided for effecting a driving connection between the countershafts and the main shaft.

    摘要： An improved, blocked, change gear transmission utilizing at least one improved resilient jaw clutch assembly to selectively engage a selected gear to a shaft is provided. The improved jaw clutch assembly comprises two axially engageable jaw clutch members and a blocker mechanism to prevent engagement of the jaw clutch members until the jaw clutch members are rotating at a substantially synchronous speed. Preferably, one of the jaw clutch members carries axially and radially outwardly extending external clutch teeth designed for selective interengagement with axially and radially inwardly extending internal jaw clutch teeth carried by the other jaw clutch member. The improvement comprises providing a back-lash between the interengageable clutch teeth which is substantially greater than the back-lash normally utilized with similar clutch assemblies, said increased back-lash being in the range of five to fifteen times greater than normal back-lash and preferably about ten times greater than normal back-lash.
