A left-right wheel driving device (10) is provided with two motors (1, 2) that drive left and right wheels, and a gear mechanism (3) that amplifies and transmits, to the left and right wheels, a torque difference between the two motors (1, 2), with respective axles (1A, 2A) of the two motors (1, 2) being concentrically disposed. The left-right wheel driving device (10) comprises: motor shafts (11) which are positioned concentrically with the axles (1A, 2A) and between the axles (1A, 2A), and on which motor gears (21) are interposed; counter shafts (12) that are disposed parallel to the motor shafts (11), and on which first intermediate gears (22) that engage with the motor gears (21) and second intermediate gears (23) having a smaller diameter than the first intermediate gears are interposed; and output shafts (13) which are disposed parallel to the motor shafts (11), and on which output gears (24) that engage with the second intermediate gears (23) are interposed. The gear mechanism (3) is disposed at the first end side of each of the output shafts (13), and one of the left and right wheels is disposed on the second end side of each of the output shafts.
在具备驱动左右轮的两个电机(1、2)和将两个电机(1、2)的转矩差放大并分别传递至左右轮的齿轮机构(3)的左右轮驱动装置(10)中,两个电机(1、2)的各旋转轴(1A、2A)同轴地配置。左右轮驱动装置(10)具有:电机轴(11),与各旋转轴(1A、2A)同轴且位于各旋转轴(1A、2A)之间,安装有电机齿轮(21);中间轴(12),与电机轴(11)平行地配置,且安装有与电机齿轮(21)啮合的第一中间齿轮(22)和比该第一中间齿轮小径的第二中间齿轮(23);以及输出轴(13),与电机轴(11)平行地配置,且安装有与第二中间齿轮(23)啮合的输出齿轮(24)。在输出轴(13)的一端侧配置有齿轮机构(3),在其另一端侧配置有左右轮中的一方。
