Transfer Case
The Transfer case for the E46/16 is the NV 124 manufactured by New Venture. The
primary difference between the NV 124 and the NV 125 used in the X5 SAV is that it uses
gears instead of a drive chain for torque transfer to the front axle.
The reason gears are used is to produce a
compact low profile transfer case that could
fit in the transmission tunnel of an E46 with-
out excessively limiting the forward travel of
the drivers seat.
Manufacturer:
New Venture
Type:
NV 124
Torque Distribution:
38%: 62%
Maximum Torque:
300Nm
The transfer case is only one speed and
does not use any viscous coupler.
The transmission ratio of the planetary gear
set provides a fixed torque transfer of 38:62
(front:Rear). The output speeds to the front
and rear axle are the same (1:1).
The input to the Planetary
Carrier is from the output shaft
of the transmission.
The Sun Gear of the Planetary
assembly is turned by the
Planetary Gears, the Sungear
then provides torque to the
Transfer Gear.
The Transfer Gear drives the
Output via gear-to-gear
contact. The front axle is driven
via a flange connected to the
output gear.
