Transmission Attachment to the Mounting Construction in the Vehicle
For economy reasons the cross sections of the pivoted bogie bearings are kept very small in comparison
with the diameter. This requires a rigid and torsion-resistant mounting construction for these bearings.
Additionally the supporting face for the pivoted bogie bearings and mounting of the same must also
provide the maximum evenness or flatness. (see Fig. 17)
The supporting face in the vehicle requires a mechanical machining. Inadmissible distortions or
deformations during fastening of the screws occur due to uneven locating on the frame plate or
unevenness in the locating area of the pivoted bogie bearing.
The pivoted bogie bearing must support evenly on the whole surface of the
mounting construction. If this requirement is not fulfilled the service life of
the pivoted bogie bearing reduces. Additionally, the reliability in service is
put at risk.
Shape alternatives of the locating face require a written approval by ZF,
which however will only be given after a preceding installation investigation.
