The additional cross member enables support
over a longer lever arm, which positively influ-
ences vibration and load cycle characteristics.
The aluminium cross member is bolted to the
body as well as to the rear subframe mount-
ings and, in addition to its supporting func-
tion for the gearbox mounting, serves as a
body-stiffening tunnel bridge.
Mechanical unit mountings
Running gear
The three-point mechanical unit mount-
ing is used for all engine/gearbox
combinations except those including
the 01V 5-speed automatic gearbox.
A newly designed three-point mechanical unit
mounting is used in the new Audi A4.
The hydraulically damped engine mountings
(electrically-controlled version for diesel
engines) are fastened directly to the longitu-
dinal members via die-cast aluminium brack-
ets.
The gearbox mounting is effected by means
of a conventional rubber bearing on a body-
mounted aluminium carrier, which is pro-
duced according to the hollow sand casting
technique.
