Publication number: 20220289355Abstract: In a marine propulsion apparatus that transmits power of at least one of an internal combustion engine (ICE) and a generator motor (GM) mounted on a ship to a propeller via a forward reverse switching mechanism, the marine propulsion apparatus can be downsized as a whole. The marine propulsion apparatus includes a connection switching mechanism capable of selectively connecting the GM to an upstream side and a downstream side of the power transmission from the ICE in the forward reverse switching mechanism. Then, the forward reverse switching mechanism is interposed between the ICE and the connection switching mechanism, and a large torque from the ICE is not directly transmitted to the connection switching mechanism. As a result, it is not necessary to increase the capacity of the connection switching mechanism, and the connection switching mechanism and thus the marine propulsion apparatus can be downsized.Type: ApplicationFiled: July 20, 2020Publication date: September 15, 2022Inventors: Koji KIYOOKA, Tomoyuki EBIHARA, Takashi NISHIZAWA, Koga YAMANE, Kengo SASAHARA, Shigeaki NAKAGAWA, Kazuki YASUI, Toshiaki OKANISHI

Patent number: 10807458Abstract: An axle driving apparatus may include a first rotary shaft connected to an internal combustion engine; a second connected to an electric motor; a third rotary shaft connected to a driving shaft of a wheel; an interlocking unit interlocking the first, second, and third rotary shaft; and an input and output switchover unit. The interlocking unit and the input and output switchover unit are structured to switch the interlocking unit between a first mode in which only the power of the internal combustion engine is output from the third rotary shaft, a second mode in which only the power of the electric motor is output from the third rotary shaft, a third mode in which the power of the internal combustion engine and the power of the electric motor are combined and output from the third rotary shaft, and a fourth mode in which the power of the internal combustion engine is output from the second rotary shaft to the electric motor.Type: GrantFiled: August 8, 2018Date of Patent: October 20, 2020Assignee: KANZAKI KOKYUKOKI MFG. CO., LTD.Inventors: Takashi Nishizawa, Tasuku Inoue, Hiroaki Hashima, Yoshitaka Kochidomari, Fumiaki Ito, Masato Arata, Koga Yamane

Patent number: 9759310Abstract: A transaxle comprises a hydrostatic transmission (HST), an axle, a gear train interposed between the HST and the axle, a casing and a partition. The casing defines an HST chamber and a gear chamber. The HST is disposed in the HST chamber. The gear train and the axle are disposed in the gear chamber. The partition is disposed in the casing so as to separate the HST chamber and the gear chamber from each other. The partition has an opening through which a hydraulic motor of the HST passes to extend from the HST chamber into the gear chamber so as to be drivingly connected to the gear train. The partition obstructs a flow of fluid between a fluid sump in the HST chamber from a fluid sump in the gear chamber.Type: GrantFiled: April 10, 2015Date of Patent: September 12, 2017Assignee: Kanzaki Kokyukoki Mfg. Co., Ltd.Inventors: Toshifumi Yasuda, Daisuke Murashima, Koji Iwaki, Hiroki Maehara, Koga Yamane
