    • PROBLEM TO BE SOLVED: To overcome a disadvantage of a phase alignment member that its natural frequency is relatively low and it vibrates when an engine speed becomes 1000 to 1500 rpm, for example.SOLUTION: This invention relates to a torque transmission device for a vehicle that is mounted between a torque input element 7 and a torque output element 24 and includes at least two elastic members 10a, 10b acting against a relative rotation between the torque input element and the torque output element. The elastic members 10a, 10b are arranged in series through a phase alignment member 30 so that they are deformed in the phase relative to each other. A spring constant K1 of the elastic member 10a fixed between the torque input member 7 and the phase alignment member 30 is smaller than a spring constant K2 of the elastic member 10b fixed between the phase alignment member 30 and the torque output element 24, and a ratio K2/K1 is equal to at least 2.
    • 要解决的问题:为了克服固有频率相对较低的相位对准构件的缺点,并且当发动机转速变为1000〜1500rpm时,相位对准构件的振动。解决方案本发明涉及一种用于车辆的转矩传递装置 其安装在转矩输入元件7和转矩输出元件24之间,并且包括至少两个弹性元件10a,10b,其抵抗扭矩输入元件和扭矩输出元件之间的相对旋转。 弹性构件10a,10b通过相位对准构件30串联布置,使得它们相对于彼此相位变形。 固定在扭矩输入构件7和相位对准构件30之间的弹性构件10a的弹簧常数K1小于固定在相位对准构件30和扭矩输出元件24之间的弹性构件10b的弹簧常数K2, 比率K2 / K1等于至少2。
