GEAR-CAM MECHANISM OF A DIFFERENTIAL

Cage 1 rotates about fixed axis x-x and has radial slots in which inserts (teeth) 2 can slide. Keyed to semiaxles A and B are cam disks 4 and 3. Disk 3 has an external profiled (cam) surface and disk 4 a corresponding internal one. The number of cam lobes on disks 3 and 4, and the number of inserts 2 are selected so that when cage 1 rotates, corresponding torques are transmitted to disks 3 and 4 and, consequently, to semiaxles B and A which, at the same time, can rotate at the same or different speeds, depending upon the load torque applied to each semiaxle.
