    摘要： A drive device for an electrically driven axle of a motor vehicle may include at least one electric machine, a shiftable transmission connected downstream from the at least one electric machine, and a differential coupled to the transmission for distributing drive torque to the axle. The transmission has first and second planetary gear sets connected in series. The at least one electric machine engages with an external toothing of a ring gear of the first planetary gear set. A carrier of the first planetary gear set is rotationally fixed to a sun gear of the second planetary gear set. A sun gear of the first planetary gear set is detachably couplable to a housing. A ring gear of the second planetary gear set is coupled to the housing. A carrier of the second planetary gear set is an output of the transmission. The first planetary gear set is interlockable.

    摘要： A drive axle for an electric vehicle which comprises first and second electric machines (EM1, EM2), first and second drive wheels (R1, R2) and first and second two-speed transmissions (G1, G2) each having the same gear ratios. The first electric machine (EM1) drives the first drive wheel (R1) by way of the first two-speed transmission (G1) and the second electric machine (EM2) drives the second drive wheel (R2) by way of the second two-speed transmission (G2). The first and the second two-speed transmissions (G1, G2) each comprise a first planetary gearset (PS1) and a second planetary gearset (PS2) coupled to one another. The first planetary gearset (PS1) and the second planetary gearset (PS2) each comprise a web shaft (ST1, ST2), a ring-gear shaft (HR1, HR2) and a sun-gear shaft (SO1, SO2).

    摘要： A transmission having a main transmission and a splitter group, and including at least four spur gear planes formed with a countershaft and at least five shifting elements for engaging at least six gears between the transmission input and output shafts. When shifting between gears with the highest and the second-highest gear ratios, a shift occurs in the shifting elements associated with the splitter group but not in the shifting elements associated with the main transmission, whereas when shifting between gears with the lowest and second-lowest gear ratios, a shift occurs in the shifting elements associated with the main transmission but not in the shifting elements associated with the splitter group. An electric machine can be connected by a gearset, and depending on its shift position, the gearset acts as a pre-transmission ratio for the electric machine or as a superimposition transmission.

    摘要： A multi-speed transmission has drive and output shafts, three front-mounted and two rear-mounted planetary gear sets, and shift elements which can be engaged to selectively implement at least eleven forward gears and one reverse gear. The front gear sets are connected to one element of the rear gear sets. Five shift elements are assigned to the front gear sets and two are assigned to the rear gear sets, such that the front gear sets transmit seven output speeds to the rear gear sets. If normalized to the input speed of the drive shaft, at least one output speed of the front gear sets is less than 0, one output speed is greater than 1, one output speed is equal to 0, one output speed is equal to 1 and two output speeds are between 0 and 1.
