Gear arrangement is bypassed by parallel axes, and the parallel axes is in the state in motor vehicle preferably below gear arrangement
Extension.
Provide in particularly preferred embodiments, differential mechanism is satellite differential, the satellite differential
With gear ring, sun gear and planet carrier as its second output shaft, two group of first and second planetary gear can be rotationally arranged at
On planet carrier, wherein, on the one hand the first planetary gear engages with gear ring, on the other hand engaged with the second planetary gear, the second planetary gear
On the one hand engage with the first planetary gear, on the other hand engaged with sun gear, and wherein, the first vehicle bridge flange e axle supporting sun
Wheel, planet carrier supporting the first bypass spur gear.That is, the first vehicle bridge flange shaft is configured to support the solar shaft of sun gear, the second car
Bridge flange shaft significantly separates with differential mechanism vertically, and the second vehicle bridge flange shaft must be relative to the first vehicle bridge flange shaft coaxially
Arrangement, wherein, the connection with planet carrier is not formed coaxially with differential mechanism central axial line, but is made up of parallel axes.Institute
Parallel axes is stated to be connected with planet carrier by first gear level on its first end.Planet carrier especially supports the first bypass commutating tooth
Wheel, the first bypass spur gear and the first bypass little gear engagement corresponding, on parallel axes.Pass through the other end in parallel axes

Tooth to, on the other hand second bypass spur gear and second bypass little gear tooth to oblique with corresponding tooth opposed to each other
Face.So that axial force that is caused, acting on parallel axes is cancelled out each other.This greatly simplify the supporting of parallel axes.Especially
What it needed is only a radial support of parallel axes.This is preferably carried out in two ends of parallel axes.It is it means that parallel
Axle arranges journal bearing, especially roller bearing on each of which end.This bearing substantially only can bear radial load.As above institute
State, what is acted on parallel axes is not axial force, because axial force is cancelled out each other by bypassing the opposed helical teeth of gear stage.
Due to being diametrically preferably realised as difference between bypass spur gear and bypass little gear, had on parallel axes
Higher rotation speed.Therefore parallel axes is easy to radial vibration.In order to avoid radial vibration is in other words in order to which radial vibration is reduced to can
The degree of receiving, provided in the improved design project of the present invention, parallel axes is also supported by centre, is especially radially supported.
Needle bearing can be used for this, and needle bearing is particularly advantageous in terms of the installing space of radial direction.
