Patent number: 11535099Abstract: [Technical problem] To provide a power transmission mechanism for a four-wheel drive vehicle in which a prime mover is disposed at a low position to lower the center of gravity of the vehicle while a driving path from a transmission to a front wheel differential mechanism is also shortened. [Solutions] In a power transmission mechanism for a four-wheel drive vehicle, the power of a prime mover is transmitted to a front wheel differential mechanism which is disposed in front of the prime mover, and to a rear wheel differential mechanism which is disposed behind a transmission, through the transmission which is disposed behind the prime mover. The transmission comprises a front and rear wheel drive shaft that extends along the longitudinal direction of the vehicle body. The transmission is arranged separately from the prime mover and a rear axle drive device. The rear end portion of the front and rear wheel drive shaft is connected to an input shaft of the rear wheel differential mechanism.Type: GrantFiled: December 23, 2019Date of Patent: December 27, 2022Assignees: KANZAKI KOKYUKOKI MANUFACTURING CO., LTD., KAWASAKI MOTORS, LTD.Inventors: Keisei Shimazaki, Michio Tsukamoto, Ayumi Hamada
