The invention relates to a method for operating a transmission device (1) for a motor vehicle (2), which transmission device has an input shaft (6), which is operatively connectable to a drive deviceof the motor vehicle (2), and also a first output shaft (7) and a second output shaft (8), and has a spur gear differential transmission (15), configured as a planetary transmission, by means of whichthe input shaft (6) and an intermediate shaft (24) are coupled to the first output shaft (7) and the second output shaft (8). An electric machine (25) is coupled to the input shaft (6) in a first shift position of a shift device (26) and is coupled to the intermediate shaft (24) in a second shift position of the shift device (26). The electric machine (25) is operated when the first shift position is provided in order to apply a torque to the input shaft (6) and when the second shift position is provided in order to provide a differential torque and/or a differential speed between the first output shaft (7) and the second output shaft (8), the electric machine (25) being operated at a speed different from zero when the differential torque is zero and/or the differential speed is zero. Theinvention further relates to a transmission device (1) for a motor vehicle (2).
本发明涉及一种用于运行机动车(2)的传动设备(1)的方法,该传动设备具有能与机动车(2)的动力设备作用连接的输入轴(6)、第一输出轴(7)、第二输出轴(8)、设计为行星齿轮传动机构的圆柱齿轮差速器(15),输入轴(6)和中间轴(24)通过该圆柱齿轮差速器与第一输出轴(7)和第二输出轴(8)耦联。在切换装置(26)的第一切换位置中使电机(25)与输入轴(6)耦联,在切换装置(26)的第二切换位置中使电机与中间轴(24)耦联。在存在第一切换位置的情况下电机(25)被运行以对输入轴(6)施加转矩,在存在第二切换位置的情况下电机被运行以在第一输出轴(7)与第二输出轴(8)之间提供转矩差和/或转速差,在转矩差为零和/或转速差为零时电机(25)以非零转速运行。本发明还涉及一种用于机动车(2)的传动设备(1)。
