  • Power train and motor grader
    Patent number: 10539208
    Abstract: A power train is provided having a reduced size and weight. A hydraulic motor includes a rotatable output shaft. Wheel bearings rotatably support a rotatable housing relative to a motor housing. A hydraulic clutch mechanism permits or prohibits rotation of a second carrier of a second planetary gear reducer about the center of rotation of the output shaft. The hydraulic clutch mechanism is disposed on the radially inner side relative to the wheel bearings.
