Two driver elements 21,22 can move independently of one another, for example, in German laid-open document DE 10 2,010 022 751 A1, DE 10 2,010 025 454 A1 that mention in beginning and DE 10 2,010 049 931 A1, describe.
Two driver elements 21,22 preferably relate to two less combustion engines, and described combustion engine can operation independently of one another in passenger carrying vehicle.Can be by power distribution change-speed box and diff 28 separately or one be used from driving passenger carrying vehicle in the situation that two combustion engines 21,22 connecting two power- transfer clutchs 31,32 in centre.
Change-speed box-driving engine-assembly 11 shown in Figure 1 comprises first point of change-speed box 40, and this point of change-speed box configures to the first driver element 21 and be embodied as main gearbox.This main gearbox 40 is made up of two single planetary gear change-speed box groups 41,42. Planetary gearbox group 41 and 42 comprises respectively sun wheel, hollow wheel gear and multiple planetary wheel, and described planetary wheel is rotatably installed on planetary gear carrier.Between two planetary gearbox group 41,42 planetary gear carriers in the first planetary gearbox group 41 and the hollow wheel gear of the second planetary gearbox group 42, intercouple.

In table 1, alphabetical S delegated path.Show the coupling between the planetary gear carrier of the first planetary gearbox group 41 and the hollow wheel gear of the second planetary gearbox group 42 by path 1.Show second planetary gear carrier of planetary gearbox group 42 and the coupling of hunting gear by path 2.
Four gears 1,2 and 4,5 are for the operation with driver element 21.Therefore, can be implemented to the speed of about 120 to 140 kilometers by driver element or combustion engine 21.
The connection of the second combustion engine 22 realizes by intermediate gear change-speed box 45, and this intermediate gear change-speed box is second point of change-speed box of power distribution change-speed box shown in Figure 1.Intermediate gear change-speed box 45 is embodied as has change-speed box level i v, i r, i v3and i v6spur gear change-speed box.Intermediate gear is can relative cost cheaply manufactured, because only must determine the size of described intermediate gear for the second combustion engine 32 and the torque of mixing-electrical motor if desired.In gear 1,2,4 and 5, the second combustion engine 22 is by level i vdirect effect is on the sun wheel of the first planetary gearbox group 41.The torque realizing in described gear in the sun wheel of the first planetary gearbox group 41 is added.
Realize hand of rotation by intermediate gear stages reverse.Therefore, rotate 180 degree although be arranged in the combustion engine 22 on the right in Fig. 1, can apply two combustion engines 21,22 with identical hand of rotation.Therefore, two driver elements 21,22 can be identical.Can according to circumstances make torque and then operational power is doubled by switching on or off the second combustion engine 22.
Now, in servicely can design two other gear levels twin-engined.For this reason, first, intermediate gear must be connected to gear level i v3or i v6in.Now, in main gearbox 40, the torque of the second combustion engine 22 is no longer directed in the sun wheel of the first planetary gearbox group 41, but is directed in the sun wheel of the second planetary gearbox group 42.The rotating speed of realizing in the second planetary gearbox group 42 by this connection is added.Therefore, in the 6th gear, can realize terminal velocity completely.This gear stage also needs to have two driving engines, because for the power of a driving engine only, under this speed, resistance to motion is too large.Draw other additional gear by gear 3, this gear improve in medium speed region at twin-engined operating acceleration/accels.
Because driving engine 21 is always in operation,, can utilize traditional starter 47 to work in addition here.But must realize fast speed, comfortable starting for the second combustion engine 22, this starting can quick-make the second combustion engine 22.Therefore, have in outside motor or the effective power-transfer clutch of the flywheel in outside electrical motor 48 to the second driver element 22 configurations.Alternatively, the starting of the second driver element 22 directly realizes by the starter generator with higher torque.
In embodiment shown in Figure 1, reverse gear forms in intermediate gear.Therefore, the first combustion engine 21 can be not used in reverse gear.In the time of heavy grade, for reverse gear, the not enough torque of travelling can be supplied by motor 48.This will note in the time of definite motor 48 size.
Change-speed box-driving engine-assembly 12 is similar to change-speed box-driving engine-assembly 11 shown in Figure 1 shown in figure 2.In order to show that same or analogous part is used identical Reference numeral.Be different from Fig. 1, in Fig. 2, save intermediate gear i v3.Thus, can realize only five gears by the change-speed box-driving engine-assembly 12 in Fig. 2.But, can be designed more in phase for the gear classification of monomotor operation, because do not need higher gear to jump between gear 2 and gear 4 for this reason.Therefore, although total possible classification has reduced a bit, but draw level jump unified between each gear.
In addition, show independently motor 50 with speed changer structure in Fig. 2, advantageously, this motor can be applied as the starter of two driver elements or combustion engine 21,22.The starting by motor or starter generator 50 of two combustion engines 21,22 by arranging gear and arranging that in the second combustion engine 22 power-transfer clutch 32 realizes in spur gear change-speed box 45.In order to start the first combustion engine 21, open power-transfer clutch K1 and drg B1 and closed power-transfer clutch K2 and drg B2, that is to say in vehicle stationary state.Closed power-transfer clutch K2 and drg B2 guarantee do not have pull-up torque to be delivered on hunting gear in the time of starting the first combustion engine 21.
