POWER TRANSMISSION DEVICE

摘要

A partition plate is provided in a case to separate a first space where a CVT is disposed and a second space where a forward/backward travel switching mechanism and a differential gear are disposed. Bearings respectively supporting an input cone and an output cone and formed as pure rolling cylindrical roller bearings are disposed in the first space. A bearing supporting one end of an input shaft and formed as a conical roller bearing capable of receiving thrust force, a bearing supporting an output shaft and formed as a conical roller bearing capable of receiving thrust force, and a bearing supporting one end of the output cone are disposed in the second space. The first space and the second space are sealed by oil seals. The first space is filled with traction oil and the second space is filled with lubricating oil.
