用于机动车的扭矩传递装置
摘要：
本发明涉及用于机动车的扭矩传递装置，扭矩传递装置包括扭矩输入元件(7)、扭矩输出元件(24)、和至少两个弹性机构(10a、10b)，弹性机构安装在扭矩输入元件(7)和扭矩输出元件(24)之间，抵抗扭矩输入元件和扭矩输出元件相对于彼此的转动而起作用。弹性机构(10a、10b)通过定相机构(30)串联布置，以便弹性机构(10a、10b)彼此在相位上发生变形。安装在扭矩输入元件(7)和定相机构(30)之间的弹性机构(10a)的硬度K1小于安装在定相机构(30)和扭矩输出元件(24)之间的弹性机构(10b)的硬度K2，K2／K1之比至少等于2。
摘要（英）：

The present invention relates to a torque transmission device for a motor vehicle, having a torque input element (7), a torque output element (24), and at least two elastic members (10a, 10b) mounted between the torque input and output elements (7, 24) and counteracting rotation of input and output elements with respect to one another. The elastic members (10a, 10b) are arranged serially by means of a phasing member (30) so that the elastic members (10a, 10b) deform in phase with one another. The stiffness K1 of the elastic member (10a) mounted between the torque input element (7) and the phasing member (30) is less than the stiffness K2 of the elastic member (10b) mounted between the phasing member (30) and the torque output element (34), the ratio K2/K1 being equal to at least 2.
