Accompanying drawing explanation
Other features can be drawn by the description to accompanying drawing.
Wherein:
Fig. 1 shows transfer transmission device, and wherein, it is inner that the gear ring of the planetary gear mechanism of the transmission device that is configured to shift gears is arranged in the gear ring of the planetary gear mechanism that is configured to differential drive mechanism; And
Fig. 2 shows transfer transmission device, and wherein, it is inner that the gear ring that is configured to the planetary gear mechanism of differential drive mechanism is arranged in the gear ring of planetary gear mechanism of the transmission device that is configured to shift gears.
The specific embodiment
Fig. 1: 2 effects of axle drive shaft 1 and gearshift are connected, wherein, in the drive range illustrating, the torque of axle drive shaft is delivered on the gear ring 3 as the planetary gear mechanism 4 of gear switching transmission device by gearshift.The planetary gear mechanism 4 that switches transmission device as gear is comprised of gear ring 3, planetary wheel 5, sun wheel 6 and pinion carrier 7.In the second drive range of gearshift 2, the torque of axle drive shaft is transmitted in pinion carrier 7.Here, gearshift 2 is shown in broken lines.For example, by sun wheel 6 is connected in anti-relative rotation with unshowned housing, sun wheel 6 positions keep regularly.Adjacent to planetary gear mechanism 4 ground that switch transmission device as gear, be furnished with the planetary gear mechanism 8 as differential drive mechanism, it is comprised of gear ring 9, planetary wheel 10, sun wheel 11 and pinion carrier 12.Pinion carrier 12 is connected in anti-relative rotation with pinion carrier 7 or integrally constructs with this pinion carrier.Sun wheel 11 is connected with the second output shaft 14 effects by cylindrical wheel level 13.Gear ring 9 is connected in anti-relative rotation with the first output shaft 15.By the planetary gear mechanism 8 as differential drive mechanism, be equilibrated at the speed discrepancy between the first output shaft 15 and the second output shaft 14.If other gearshift 16 is operated in closed meaning, pinion carrier 12 is connected and has got rid of the balance between the first output shaft 15 and the second output shaft 14 in anti-relative rotation with sun wheel 11 so.If other gearshift 16 is opened in other words conj.or perhaps by operation in the meaning of opening, in the connection between pinion carrier 12 and sun wheel 11, be interrupted and can again carry out the balance between the first output shaft 15 and the second output shaft 14 so.The first output shaft 15 is pivot center and the pivot center of sun wheel 6 and sun wheel 11 and the coaxial of the axle drive shaft 1 ground layout of the first output shaft in other words.In two drive ranges of gearshift 2, transfer transmission device can move for more time, this is because the in the situation that of drive shaft turns, has occurred being configured to that gear switches the planetary gear mechanism 4 of transmission device and as the rolling in the engaging piece of the planetary gear mechanism 8 of differential drive mechanism.
Fig. 2: axle drive shaft 1 is not to be connected in anti-relative rotation with pinion carrier 7 exactly with gear ring 3 by gearshift 2.Gear ring 9 is arranged in gear ring 3 inside.In cross-country gear, axle drive shaft 1 is anti-to be connected with gear ring 3 in relative rotation, and keeps regularly because of sun wheel 6 positions, so pinion carrier 7 is driven and drive equally pinion carrier 12.This pinion carrier drives gear ring 9 and sun wheel 11, the first output shaft 15 and the second output shaft 14 by planetary wheel 10.Other gearshift 16 is arranged between cylindrical wheel level 13 and the first output shaft 15 and sun wheel 11 is connected with gear ring 9.
