| 摘要 | A continuously variable transmission includes a continuously variable transmission mechanism that includes an input disk, an output disk, and planetary balls sandwiched between them and that steplessly changes a transmission ratio between the input disk and the output disk by tilting the planetary balls, wherein cooling performance of a cooling device for the continuously variable transmission mechanism is enhanced as the transmission ratio becomes larger than 1 or smaller than 1. | ||

| 主权项 | 1. A continuously variable transmission including a continuously variable transmission mechanism that includes an input member, an output member, and rotary members sandwiched between them and that steplessly changes a transmission ratio between the input member and the output member by tilting the rotary members, the continuously variable transmission comprising: a cooling device configured to cool the continuously variable transmission mechanism by supplying coolant thereto in such a manner that flow rate of the coolant is increased as the transmission ratio becomes larger than 1 or smaller than 1, wherein the continuously variable transmission mechanism is incorporated in a rotary electrical machine, and wherein the cooling device also cools the rotary electrical machine. | ||
