具有四缸发动机的机动车动力总成系统
摘要：
本发明涉及一种机动车动力总成系统，该机动车动力总成系统具有一个构造成四缸发动机的内燃机(266)以及一个液力变矩器装置，该液力变矩器装置具有一个由两个能量储存装置(272，276)组成的扭转振动减振器和一个变矩器跨接偶合器(268)。涡轮(274)设置在这两个能量储存装置(272，276)之间。根据权利要求1的特征部分，要求下列参数的值范围或关系范围的权利：最大发动机力矩Mmot，max(266)，弹簧刚度C1(272)，惯性矩J1(274)，弹簧刚度C2(276)，惯性矩J2(278)和变速器输入轴(280)的弹簧刚度CGEW。根据说明书，要在这两个能量储存装置(272，276)之间设置大的惯性矩J1并且要在扭转振动减振器与变速器输入轴之间设置尽可能小的质量。图5示出了在变矩器跨接偶合器(268)闭合的情况下弹簧－质量等效线路图。
摘要（英）：

The invention relates to an automotive drive train having an internal combustion engine (266) that is configured as a four-cylinder engine and a hydrodynamic torque converter device. Said device has a torsional vibration damper consisting of two energy accumulating devices (272, 276) and a converter lockup clutch (268). The turbine wheel (274) is interposed between the two energy accumulating devices (272, 276). According to the invention, ranges of values or ratios for following parameters are claimed: maximum engine torque Mmot,max (266), spring rate C1 (272), mass moment of inertia J1 (274), spring rate C2 (276), mass moment of inertia J2 (278) and spring rate CGEW of the transmission input shaft (280).; The mass moment of inertia J1 should be high between the two energy accumulating devices (272, 276) and masses should be as little as possible between the torsional vibration damper and the transmission input shaft. Figure 5 shows a spring-mass equivalent circuit diagram with closed converter lockup clutch (268).
