Patent number: 10364875Abstract: A micro-traction drive unit according to the present invention includes an inner ring, an outer ring, a plurality of rolling elements, a retainer, a micro-traction drive case and a power-transmitting shaft coaxial with the inner ring and incapable of relative rotation around an axis to the retainer. An opposite end of the power-transmitting shaft from the inner ring forms an input end operatively connected to a driving source. An input end of the pump shaft is detachably connected to a central hole of the inner ring in a state incapable of relative rotation around the axis via the access opening of the micro-traction drive case by connecting the micro-traction drive case to the HST case so as to surround the input end of the pump shaft of the HST.Type: GrantFiled: February 17, 2016Date of Patent: July 30, 2019Assignee: Kanzaki Kokyukoki Mfg. Co., Ltd.Inventors: Koji Iwaki, Etsuo Miyake

Patent number: 10337570Abstract: A transaxle includes a transaxle casing, a bi-directional overrunning clutch in the transaxle casing, a friction mechanism, and a clutch-off biasing mechanism. The bi-directional overrunning clutch includes coaxial input and output members journalled by the transaxle casing, and includes a cage disposed between the input member and the output member. Rollers carried by the cage are rotatable to follow rotation of the output member. The cage is rotatable relative to the input member according to the rotation of the rollers following the output member until the rollers contact the input member to engage the bi-directional overrunning clutch. The friction mechanism applies a friction resistance to the cage to rotate the cage relative to the input member. The clutch-off biasing mechanism biases the cage to the initial position. The friction mechanism and the clutch-off biasing mechanism are distributed in the transaxle casing at first and second end portions of the cage.Type: GrantFiled: October 14, 2016Date of Patent: July 2, 2019Assignee: KANZAKI KOKYUKOKI MFG. CO., LTD.Inventors: Michio Tsukamoto, Hideaki Shokita, Etsuo Miyake

Publication number: 20170159794Abstract: In a first chamber and a second chamber formed in a casing of a transaxle, the first chamber accommodates an electric motor, and the second chamber accommodates a gear mechanism. A motor output shaft protruding from a first end of the electric motor is journalled by a partition wall formed between the first chamber and the second chamber of the casing, extended into the second chamber, and drivingly connected to the gear mechanism. In the first chamber, a motor support member is fastened with bolts to mounting bosses provided so as to be suspended from a ceiling. At least either the first end of the electric motor or a second end opposite to the first end is locked to a first plate-shaped portion of the motor support member. The motor support member is formed with, perpendicular to the first plate-shaped portion, a second plate-shaped portion for supporting electrical components.Type: ApplicationFiled: December 1, 2016Publication date: June 8, 2017Inventors: Takashi NISHIZAWA, Etsuo MIYAKE

Patent number: 8939861Abstract: A transaxle comprises a transmission differential unit including a frictional transmission mechanism and a differential mechanism. The frictional transmission mechanism includes an input shaft, a drive disc provided on the input shaft, and a driven disc whose outer peripheral edge frictionally contacts a disc surface of the drive disc. The differential mechanism includes a pair of coaxial output shafts, and a differential casing differentially connecting the output shafts to each other. The driven disc is ring-shaped and is fitted at an inner peripheral portion thereof on an outer peripheral portion of the differential casing so as to be unrotatable relative to the differential casing and so as to be slidable on the outer peripheral portion of the differential casing in the axial direction of the output shafts.Type: GrantFiled: October 10, 2012Date of Patent: January 27, 2015Assignee: Kanzaki Kokyukoki Mfg. Co., Ltd.Inventors: Fumitoshi Ishino, Etsuo Miyake, Takashi Nishizawa
