For example:
Hydraulic bellows pressure "unladen" = 50 bar
Hydraulic bellows pressure "laden" = 125 bar
The pressure input for the parameter TEBS LSV "laden" and "unladen" is sought
after.
Default:
Search for hydraulic pressure sensor, which corresponds with the measuring range
from 125 bar.
Technical data for the implementation of a hydraulic pressure sensor:
Pressure sensor "hydraulic":
0 to 250 bar => 0.5 to 4.5 V
WABCO standard EBS pressure sensor "pneumatic" as comparison value:
0 to 10 bar => 0.5 to 4.5 V
The parameter values for TEBS E are calculated as follows:
Range of measurement 250 bar: WABCO standard EBS pressure sensor 10 bar =
25 bar
Parameter value for bellows pressure "laden" => 125 bar / 250 bar *
10 bar = 5 bar
Parameter value for bellows pressure "unladen" =>
50 bar / 250 bar *10 bar = 2 bar
Input:
The entries are made via TEBS E Diagnostic Software see chapter 7.1 "Parameter
definition with TEBS E Diagnostic Software", page 125 => Window TEBS - LSV.
3.9.2.1 Mechanical suspension
Application
Vehicle with leaf spring suspension (mechanical suspension).
Only for Premium Modulator.
Purpose
Axle load determination via spring travel.
Function
The axle load information for the LSV function is derived from the compression
travel of the axle combination. ECAS distance sensors are used for this purpose. In
this particular case of application the sensor delivers a signal that is proportional to
the suspension travel and therefore the current axle load.
