针对车辆的传动系和用于执行负载变换的方法
摘要：
本发明提出了一种针对车辆的传动系和用于执行负载变换的方法，所述传动系具有至少一个电驱动装置，电驱动装置能够经由驱动轴(2)与至少一个第一传动级(i1)和第二传动级(i2)连接，其中，设置有至少一个切换装置用来切换第一传动级(i1)和第二传动级(i2)，其中，切换装置为了实施动力切换而包括至少一个形状锁合的切换元件(5)和至少一个摩擦锁合的切换元件(6、6A)，其中，每个传动级都能够利用形状锁合的切换元件(5)进行切换，并且其中，其中至少一个第二传动级(i2)不仅能够利用形状锁合的切换元件(5)进行切换，而且也能够利用摩擦锁合的切换元件(6)进行切换。
摘要（英）：

A drive-train for a vehicle with at least one electric drive, which can be coupled via a driveshaft (2) to at least a first transmission ratio stage (i1) and a second transmission ratio stage (i2). At least one shifting mechanism is provided for engaging the transmission ratio stages (i1, i2). To carry out powershifts, the shifting mechanism includes at least one interlocking shifting element (5) and at least one frictional shifting element (6, 6A). Each of the transmission ratio stages (i1, i2) can be engaged by the interlocking shifting element (5) and at least one of the transmission ratio stages (i2) can be engaged both by the interlocking shifting element (5) and by the frictional shifting element (6). Methods for carrying out a powershift, between a frictional shifting element (6, 6A) and an interlocking shifting element (5) in the drive-train, are also disclosed.
