463 084 100 0
All trailer vehicles with
lift axle
Utilisation of a lift axle for actuating the addi-
tional axle in 3-axle semitrailers for dynamic
wheelbase control.
Utilisation for the immobilizer for actuating
the spring accumulator.
Electrical actuation and monitoring are ef-
fected by TEBS E.
Traction help possible with residual pressure
maintenance.
Pulse-controlled
When using a second lift axle for
the first axle:
Up to TEBS E2: In combination
with the ECAS double block, only
the spring-returned lift axle valve
can be used on the first axle.
As of TEBS E2: An additional third
pulse-controlled valve can also be
installed.

All trailer vehicles with
tag axle.
Mechanical residual pressure maintenance.
Automatic resupply of compressed air as
soon as the pressure drops below the set
value.
Prevents the bellows from collapsing or
becoming damaged.
Optional with tag axle
Installation
It is installed for the air bellows of
the last axle see chapter 4.2 "Tag
axle control with residual pressure
maintenance", page 52.
From TEBS E2: This function can
also be generated via the internal
parameter Tag axle residual pres-
sure control see chapter 7.1 "Pa-
rameter definition with TEBS E
Diagnostic Software", page 125 =>
Window TEBS - GIO parameter 1.
External bel-
lows pressure
sensor
441 044 ... 0
On one of the support
bellows of the axle to
be monitored.
On the yellow coupling
head.
Axle load measurement.
Measurement pressure at the yellow cou-
pling head.
The bellows pressure sensor provides an
optimal actuation for braking pressure on the
last axle when unladen; this brake pressure
is calculated on the last axle depending on
the respective pressure (by loading or vibrat-
ing the vehicle frame) thereby preventing the
wheels from blocking.
Optional
Installation
The external bellows pressure
sensor must be installed depend-
ing on the construction of the vehi-
cle frame and under the responsi-
bility of the vehicle manufacturer
with an especially flexible and soft
frame.
