POWER TRANSMISSION DEVICE

摘要

A partitioning plate (21d) is provided inside a case (21) and separates from each other a first space in which a CVT (30) is mounted and a second space in which a forward-reverse switching mechanism (24) and a differential gear (28) are mounted. In the first space are arranged bearings (42, 46) formed as cylindrical roller bearings functioning purely as rolling bearings for respectively supporting an input cone (34) and an output cone (36). In the second space are arranged a bearing (41) formed as a tapered roller bearing for supporting one end of an input shaft (32) and capable of receiving thrust force, a bearing (49) formed as a tapered roller bearing for supporting an output shaft (38) and capable receiving thrust force, and a bearing (45) for supporting one end of the output cone (36). The second space is sealed by oil seals (43, 47). Traction oil is placed in the first space and lubricating oil is placed in the second space.
