TRANSMISSION HAVING A CONTINUOUSLY OR INFINITELY VARIABLE VARIATOR DRIVE |
摘要 |
A transmission having a variator drive capable of being placed in a continuously variable operating mode or an infinitely variable operating mode, capable of having a wide ratio range, and capable of transmitting large amounts of power. Variable transmissions comprising three clutches, three grounding clutches or brakes, and a variator comprising a plurality of tilting variators balls disposed between a first drive ring and a second drive ring allow a single variator to function as an infinitely variable transmission when power is inputted to the carrier assembly and as a continuously variable transmission when power is inputted through a first ring assembly. Certain embodiments include a differential that allows a parallel power path around the variator to improve the variator torque capacity and a direct drive mode to improve the efficiency of the variator. |
