Patent number: 11987318Abstract: A leaning vehicle includes a vehicle body, a left front wheel, a right front wheel, a lean mechanism, a lean brake mechanism, a steering handle, a left grip, a throttle grip, a lean brake manipulator. The lean mechanism causes the left front wheel and the right front wheel to lean about a front-rear direction as a rotation center when the vehicle body leans about the front-rear direction as a rotation center. The lean brake mechanism brakes the leaning operation by the lean mechanism while the leaning vehicle is traveling. The lean brake manipulator is positioned at a first side in the vehicle width direction, changes a position integrally with the left grip, and for performing an operation of actuating the lean brake mechanism to brake.Type: GrantFiled: December 9, 2020Date of Patent: May 21, 2024Assignee: KAWASAKI MOTORS, LTD.Inventors: Takeshi Nakajima, Hiroshi Ishii, Taro Iwamoto, Kazuya Nagasaka, Taichi Inaba

Publication number: 20230037344Abstract: A leaning vehicle includes a vehicle body, a left front wheel, a right front wheel, a lean mechanism, and a suspension. The left front wheel is positioned on the first side (left side) in the vehicle width direction. The right front wheel is positioned on the second side (right side) opposite to the first side in the vehicle width direction. The lean mechanism connects the left front wheel and the right front wheel and vertically vibrates integrally with both of the left front wheel and the right front wheel. The suspension is positioned so as to overlap the center of the vehicle in the vehicle width direction, connects the lean mechanism to the vehicle body, and reduces vibration transmitted from a road surface to the vehicle body via the left front wheel and the right front wheel.Type: ApplicationFiled: December 9, 2020Publication date: February 9, 2023Inventors: Takeshi NAKAJIMA, Hiroshi ISHII, Taro IWAMOTO, Kazuya NAGASAKA, Taichi INABA
