Title: (EN) Method for transmitting and damping torques
(ZH) 用于传递和衰减转矩的方法
Abstract: front page image
(EN) The invention relates to a method for transmitting and for damping an average torque (Mm) having a superimposed alternating torque (Mw) in a torque transmission arrangement (1) for a drive train of amotor vehicle, comprising an input region (25) that can be rotated about an axis of rotation (A) and an output region (35) that can be rotated about an axis of rotation (B), wherein the average torque(Mm) having the superimposed alternating torque (Mw) is transmitted along a torque path (M) from the input region (25) to the output region (35), wherein the input region (25) of the torque transmission arrangement (1) rotates at an input speed (ne) about the axis of rotation (A), and the output region (35) of the torque transmission arrangement rotates at an output speed (na) about the axis of rotation (B), wherein at least the input speed (ne) is composed of an average torque (nem) and a superimposed alternating term (newp), wherein the alternating term (new) can be described approximatelyby means of superimposing periodic speed oscillations (newp_i), the frequencies (f) of which are substantially in an integer relationship (i) with respect to the ignition frequency (Zf), wherein eachof these periodic oscillations (newp_i) has a minimum (newp_i_min) and a maximum (newp_i_max), wherein a slip arrangement (30) is provided in the torque path (M) between the input region (25) and theoutput region (35) for transmitting the average torque (Mm) having the superimposed alternating torque (Mw) and for generating a speed slip (ns) between the speed ne and the speed na in the torque path (M), wherein the slip arrangement (30) provides a maximum of an external activation (40) of the speed slip (ns) in the region of the maxima (newpi_i_max) of at least one periodic oscillation term (newp_i) of the alternating term (newp), and provides a minimum of an external activation (45) of the speed slip (ns) in the region of the minima (newpi_i_min) of at least one periodic oscillation term(newp_i) of the alternating term (new).
(ZH) 一种用于在机动车的传动系的转矩传递组件(1)中传递和衰减具有叠加的交变力矩(Mw)的平均转矩(Mm)的方法,该转矩传递组件包括可围绕转动轴线(A)转动的输入区域(25)和可围绕转动轴线(B)转动的输出区域(35),其中,具有叠加的交变力矩(Mw)的平均转矩(Mm)沿着转矩路径(M)从输入区域(25)传递至输出区域(35),其中,转矩传递组件(1)的输入区域(25)以输入转速(ne)围绕转动轴线(A)旋转,并且转矩传递组件的输出区域(35)以输出转速(na)围绕转动轴线(B)旋转,其中,至少输入转速(ne)由平均转速(nem)和叠加的交变部分(newp)组成,其中,交变部分(new)可近似通过叠加周期性的转速振动(newp_i)来说明,其频率(f)基本上是点火频率(Zf)的整数的比例(i),其中,周期性的振动(newp_i)中的每个具有最小值(newp_i_Min)和最大值(newp_i_Max),其中,在输入区域(25)和输出区域(35)之间的转矩路径(M)中的滑动组件(30)设置成传递具有叠加的交变力矩(Mw)的平均转矩(Mm)并且产生在转矩路径(M)中在转速ne和转速na之间的转速滑移(ns),其中,滑动组件(30)在交变部分(newp)的至少一个周期性的振动成分(newp_i)的极大值(newpi_i_Max)的范围中提供转速滑移(ns)的外部激活(40)的最大值,并且在交变部分(new)的至少一个周期性的振动部分(newp_i)的极小值(newpi_i_Min)的范围中提供转速滑移(ns)的外部激活(45)的最小值。
