Drive mechanism for infinitely variable transmission

A transmission transmission device, comprising the input shaft (18), which is mounted on the input shaft and input plate which is in (10) and input plate relative and output plate of a circumvolution (12); the input disc and output plate of the annular cavity of them. The rolling bodies (14,16) is located in the annular cavity, and first and second holding frame, the first rolling body and a second rolling body rotatable are arranged on the first and second rolling body, the input end (34,36) on the rolling body and input and output contact board, thus is transmitted to drive. The rolling body is device, the rod (50) rotary shaft sleeps poorly, wherein the rod (50) rotary shaft in radial direction to surface and output disc centerline movement.
