    • PROBLEM TO BE SOLVED: To prevent the imbalance of tranction transmission capacity control, which is caused by the change of a rotation operation reaction force while a crankshaft is rotated by peculiar setting of control gain. SOLUTION: When the rotation operation reaction force Tc changes with a rotation angle θ of the crankshaft, the tranction transmission capacity control is made unstable by its overshoot or undershoot due to a response change following this change. In order to prevent this, the control gain of the tranction transmission capacity control is individually set for each crankshaft rotation angle range A, B1, B2, B3, B4, B5, B6 having almost linear characteristics of the crankshaft rotation operation reaction force (Tc), and the overshoot or undershoot is suppressed so as to realize the stability of the tranction transmission capacity control.

    • 要解决的问题:为了防止由曲柄轴通过控制增益的特殊设定而旋转时的旋转操作反作用力的变化引起的变速传动容量控制的不平衡。 解决方案:当旋转操作反作用力Tc随着曲轴的旋转角度θ而变化时,由于该变化之后的响应变化,通过其过冲或下冲使得传递能力控制变得不稳定。 为了防止这种情况,对于具有曲轴旋转操作反作用力(Tc)的几乎线性特性的每个曲轴旋转角度范围A,B1,B2,B3,B4,B5,B6,分别设定传动传动能力控制的控制增益 ),并且抑制了过冲或下冲,从而实现了传输传输容量控制的稳定性。 版权所有(C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a driving force transmission device capable of reducing the quantity of lubricating oil used for first and second gears, by reducing a useless space. SOLUTION: A hypoid gear 54 is meshed with a hypoid gear 53, and a shaft 56 is connected to an inner peripheral part of its hypoid gear 54, and driving force adjusting mechanisms 60a and 60b for transmitting driving force to rear wheel drive shafts 95a and 95b are arranged further inside its shaft 56. Thus, since the useless space can be reduced in a space for arranging the hypoid gears 53 and 54, the quantity of lubricating oil used for its hypoid gears 53 and 54 can be reduced.
