Patent number: 6561940Abstract: An output rotational driving power of the engine is split into a first split power and a second split power. The first split power is transmitted to a continuously variable speed transmission that transmits the first split power by a shearing resistance of a fluid. The second split power is transmitted to a differential planetary gear system. An output power of the continuously variable speed transmission is transmitted to the differential planetary gear system to combine the first split power and the second split power in the differential planetary gear system. A variation of a rotating speed of the output rotational driving power is absorbed by the continuously variable speed transmission to adjust an output rotating speed of the differential planetary gear system to a constant speed.Type: GrantFiled: November 29, 2000Date of Patent: May 13, 2003Assignees: Kawasaki Jukogyo Kabushiki Kaisha, NSK Ltd.Inventors: Tatsuhiko Goi, Koji Kawakami, Kenichiro Tanaka, Takayuki Isano, Hisashi Machida, Hiroyuki Ito, Shinji Miyata
