Publication number: 20230108197Abstract: A hybrid vehicle includes an engine that drives first wheel, and a motor that drives second wheel. The hybrid vehicle includes (1) a minute speed launch support mode where the hybrid vehicle is driven only by the motor as a drive source, (2) a sudden launch support mode where the hybrid vehicle is driven by the engine and motor as the drive source, and (3) a smooth launch support mode where the hybrid vehicle is driven only by the motor as the drive source in an early stage, is driven by the engine and motor in a middle stage, and is driven only by the engine in a late stage, and if an operation amount of an acceleration instruction unit is not 0 or is substantially not 0, any one of the support modes is executed according to an operation status of the acceleration instruction unit.Type: ApplicationFiled: December 9, 2022Publication date: April 6, 2023Inventors: Fumiaki ITO, Koji KIYOOKA, Tasuku INOUE, Masato ARATA

Patent number: 11541749Abstract: A moving body drive unit has an electric motor that is located inside the case and has a motor shaft extending in a first direction, a gear shaft that is located, inside the case, parallel to the motor shaft so as to extend in the first direction and has a bevel gear formed thereon, an intermediate gear mechanism that transmits power from the motor shaft to the gear shaft, and a differential gear device that is located inside the case and has a ring gear that meshes with the bevel gear to transmit power from the gear shaft to two output shafts extending in a second direction. The motor shaft and the gear shaft are arranged at different positions in both the second direction and in a third direction that is orthogonal to both the first direction and the second direction.Type: GrantFiled: October 22, 2019Date of Patent: January 3, 2023Assignee: KANZAKI KOKYUKOKI MFG. CO., LTD.Inventors: Takashi Nishizawa, Koji Kiyooka, Tasuku Inoue

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
