GEAR SYNCHRONIZER FOR A POWER TRANSMISSION Abstract of the Disclosure A synchronizer for a power transmission has a split cone ring rotatable with a ratio gear and a split bearing ring rotatable with the syn- chronizer ring. During ratio change, the syn- chronizer ring transmits a normal force to the split cone ring which develops into axial and radial components. The normal component imposes a first frictional torque on the cone ring while the radial component causes contraction of the cone ring about the split bearing to create a second frictional torque acting on the cone ring. The contraction of the cone ring causes contraction of the bearing which frictionally engages a hub on the ratio gear and transmits a third frictional torque to the hub. The three torques are additive to cause the ratio gear to accelerate or decelerate so that speed synchronizing between the shift ring, synchronizer ring and ratio gear will occur.
