    • The rotation of a first rotating element (RE1) is shifted in speed by a speed shift device (44), and is transmitted to a second rotating element (RE2) or a third rotating element (RE3) of a differential device (42) via a first clutch (C1) or a second clutch (C2). In this manner, the torque of right and left driving wheels (301, 30r) can be controlled. Furthermore, in conjunction with limitation of the differential motion, the amount of torque transmitted to a fourth rotating element (RE4) is eliminated by allowing the speed shift device (44) to freely rotate, and the accumulated amount of sliding of friction engagement elements at the time of differential motion limitation can be reduced by completely engaging the first clutch (C1) and the second clutch (C2) without allowing them to slide. Thus, the differential motion limitation control can be realized without a need to increase the size of the first clutch (C1) and the second clutch (C2). ® KIPO & WIPO 2009
    • 第一旋转元件(RE1)的旋转通过变速装置(44)在速度上移动,并且经由差动装置(42)的第二旋转元件(RE2)或第三旋转元件(RE3)经由 第一离合器(C1)或第二离合器(C2)。 以这种方式,可以控制左右驱动轮(301,30r)的转矩。 此外,结合差速运动的限制,通过允许变速装置(44)自由旋转而将摩擦接合元件的滑动量累积到第四旋转元件(RE4)的扭矩的量, 通过完全接合第一离合器(C1)和第二离合器(C2)而不允许它们滑动,可以减小差动运动限制的时间。 因此,可以实现差速运动限制控制,而不需要增加第一离合器(C1)和第二离合器(C2)的尺寸。 ®KIPO&WIPO 2009
