Tire Pressure Control (RDC)
*
Integrated rear suspension
The Tire Pressure Control system (RDC)
assumes the task of regular tire pres-
sure checks for you. The tire pressure is
monitored at all four wheels, even when
the vehicle is moving.
Behind the valve stem in every wheel,
there is an electronic chip which is
designed for severe-duty applications
and long service life. It contains a pres-
sure sensor, a transmitter and a battery.
The pressure is measured in extremely
short time intervals and then transmit-
ted by a radio signal. If an irregularity is
detected, the transmission rate is
increased.394de304
Near every wheel, there are antennas in
the body which receive the signals from
all four wheels. A central electronics
system evaluates the quadruple signals
and forwards any changes.
The RDC provides an important contri-
bution to driving safety.
The control arms on the patented inte-
grated aluminum rear axle assembly are
not mounted directly on the body. They
are mounted elastically on a chassis
sub-frame which is joined in turn with
elasticity to the vehicle body. The result-
ing double elastic suspension system
effectively absorbs the forces resulting
from bumps and road surface irregulari-
ties.
The compliance rates of the integrated
rear axle assembly's control arm mounts
have been precisely calibrated to help
provide supplementary adjustment in
the tracking angle of the rear wheels
(programmed self-steer effect). The ulti-
mate result is enhanced safety and con-
trol under all conditions.
The illustration shows the rear axle of the
sedan. With the lightweight, compact
rear axle of the sport wagon, the shock
absorbers are positioned at an angle.
