    摘要: A powertrain arrangement of a working machine, including a first and second electric motor, frame component, and transmission, the first and second electric motor being connected to the transmission for transmitting torque. The frame component forms a receiving space, in which the first and second electric motor and the transmission are accommodated. The frame component has a rear axle casing section configured to rotatably bear a universal-joint shaft connecting the transmission to a rear axle. The frame component has a top-side frame section, which is arranged adjacent to a cab floor in a vertical direction. The first and second electric motor are arranged next to each other in a transverse direction and at least partially at a same level in the vertical direction. The first and second electric motor are arranged above the rear axle casing section and below the top-side frame section in the vertical direction.

    摘要: This vehicle comprises a first dynamo-electric machine that imparts torque to a first drive wheel, a second dynamo-electric machine that applies torque to a second drive wheel, a rotation speed sensor that acquires a first rotation speed of the first drive wheel, a rotation speed sensor that acquires a second rotation speed of the second drive wheel, and a control device. The control device includes a basic setting unit that sets a basic rotation speed, a differential setting unit that sets a differential rotation speed, and an action control unit that controls the operation of the first dynamo-electric machine and the second dynamo-electric machine so that an average value of the first rotation speed and the second rotation speed becomes the basic rotation speed, and a difference between the first rotation speed and the second rotation speed reaches the differential rotation speed.

    摘要: The present invention relates to an electric vehicle and provides an electric vehicle including a main motor configured to generate a driving force, a sub-motor configured to share a rotational shaft with the main motor, and a gear unit positioned between a differential gear provided on a driving shaft and the main motor, wherein the main motor has fixed power applied after operated, and the gear unit has a gear ratio varying depending on the manipulation of an accelerator pedal, and since the main motor maintains a relatively lower rotation during traveling at a high speed, it is possible to prevent energy efficiency from being sharply reduced during traveling at a high speed.
