The housing contains two three-step transmissions. The drive shafts (1) are at the same level on the outside and the output shafts (4) are stacked in the housing centre.
Input shafts (1)
One cylindrical roller bearing FAG NU2336M.C3 and one four point bearing FAG QJ336N2MPA.C3 form the locating bearing. The floating bearing is a cylindrical roller bearing FAG NJ2336M.C3. The four point bearing is mounted with clearance in the housing (relieved) and, therefore, takes up just the axial loads. The two cylindrical roller bearings only take up the radial loads.
Intermediate shafts (2, 3)
The intermediate shafts have a floating bearing arrangement with FAG spherical roller bearings: 22348MB.C3 and 24160B.C3 for shafts 2. 23280B.MB and 24164MB for shafts 3.
Output shafts (4)
A spherical roller bearing FAG 24096B.MB is used as locating bearing. A full-complement single-row cylindrical roller bearing as a floating bearing compensates for the thermal length variations of the shaft.
The bearings are also connected to the oil circulation system for the transmission wheels. The oil (ISO VG320) is fed directly to the bearing positions from the oil filter.
