The present invention relates to and provides a drive apparatus for a four-wheel drive vehicle, which can control the drive force transmitted to each of the front, rear, left and right drive wheels only by the output control of the left and right electric motors without using a front-rear differential rotation absorption mechanism such as a coupling. The drive apparatus for an electric-motor four-wheel drive vehicle includes first and second motors, first and second differential mechanisms, and a propeller shaft. The vehicle includes a first wheel pair including first left and right wheels anda second wheel pair including second left and right wheels and positioned on opposite side to the first wheel pair in a front-rear direction. The first and second motors are configured to output first output torque and second output torque, respectively. The first differential mechanism is configured to distribute the first output torque to a first torque-transmitting member coupled to the firstleft wheel and a third torque-transmitting member coupled to the propeller shaft. The second differential mechanism is configured to distribute the second output torque to the third torque-transmitting member and a second torque-transmitting member coupled to the first right wheel.
本发明涉及并提供一种四驱车的驱动装置,能够不使用联轴器那样的前后差旋转吸收机构,而仅通过左右的电动马达的输出控制来控制向前后左右的各驱动轮传递的驱动力。电动马达式的四驱车驱动装置具备:设置于前轮侧及后轮侧中的一侧的第一马达及第二马达、与第一马达连接的第一差动机构、与第二马达连接的第二差动机构、在前轮侧和后轮侧之间传递动力的传动轴,其中第一差动机构向前轮侧或后轮侧中的一侧的左轮和前轮侧或后轮侧中的另一侧分配第一马达的输出扭矩,第二差动机构向前轮侧或后轮侧中的一侧的右轮和前轮侧或后轮侧中的另一侧分配第二马达的输出扭矩。
