Introduction of the New E-Class, Model Series 212 Sedan
Front axle
For the best possible vehicle dynamics and ease of
installation, the front axle and steering gear are prein-
stalled on a frame-type integral support together with
the engine and transmission. The remarkably rigid and
low-weight frame-type integral support is made of
high-strength steel and is bolted directly onto the
longitudinal members of the body.
An advanced principle of the three-link front axle was
selected for the front suspension. The most important
features of this are two individual links (the strut rod
and cross strut) in the lower plane, whose steering
force requirements have been reduced by means of an
additional angular guide joint.
The stabilizer bar is connected to the suspension strut
via a link rod. The strut rod, which runs diagonally
forward, is a weight-optimized forged aluminum
component while the cross strut in the transverse
direction is a weight-optimized forged steel part.
The third link is the tie rod, which forms part of the
new rack-and-pinion steering.
The arrangement and design of the wheel control
parts, and in particular the splitting of the lower wish-
bone control arm into two individual links, provide
favorable characteristics in terms of axle kinematics.
