9289A_200-594e-07.21Page 6
Strictly follow the operating instructions during mounting,
in particular concerning tightening torques for screws, the
correct tting of parts, adequate clearance for the xation
arms and safe cable installation.
Loading for the wheel force transducer and its accesso-
ries must not exceed the overload ranges and operating
temperature range specied in the data scheet.
If there is a reason to assume that these overload ranges
have been exceeded, the parts must be tested (e.g. visu-
al inspection, crack analysis, etc.).
All parts must be subjected to an inspection on each
occasion before use.
A crack test must be carried out after the rst 100 hours of
operating time.
After 500 hours of operating time, the instrument wheel
and the accessories must be subjected periodically to a
crack test.
For wheel force measurements, it is important to install
the measuring hub to the test stand correctly!
Secure all parts mounted on the shaft in accordance with
the expected forces!
2.3 How to use the instrument
The measuring hub may only be used under the
specied environmental and operating conditions.
Protect the signal output of the instrument against
contamination and do not touch it with your ngers. Fit
the cover supplied when the connection is not used.
Protect the measuring hub while it is not in use by
keeping it in the supplied transport and storage box.

3. Product description
3.1 Overview
The 5(6)-component RoaDyn S5MT/S5ST measuring
hubs are ideally suited to measure durability and tire cha-
racteristics of commercial vehicles on tire test stands.
They measure the longitudinal, transverse and vertical
forces Fx, Fy and Fz and the corresponding moments Mx,
My2) and Mz acting at the tire contact area.
RoaDyn S5MT/S5MT measuring hubs are robust, high-
precision measuring tools, equipped with four or ve high-
precision oval strain gage load cells, which are mounted
between base and top plate.
The measuring hub is stationary, i.e. base plate, top
plate and load cells are mounted non-rotating at the tire
test stand. The measuring hub incorporates a rotary axis
(shaft) with predened hub hole patterns on which the test
tire/rim combinations are mounted. This setup guarantees
optimum power ow with minimum cross talk between the
individual force components and a high natural frequency
of the complete measuring system. The shaft end is lead
through the back side of the measuring hub and is pre-
pared for installation of a driving or braking device. The
inlet and outlet ports for the oil circuit on the back of the
measuring hub are intended for lubricating and cooling of
the bearings in order to achieve constant heat conditions
even with large loads and increased rotational speeds.
2) My can only be measured when a brake is installed at the test stand,
otherwise My = 0
3.2 Features
High precision tire characteristics measurements for
commercial vehicle tires
Strain gage load cell technology for static and dynamic
tire measurements
Static measurement of vertical force Fz enables tire
test stand controlling (no additional force sensors nec-
essary)
Modular design
High rigidity
Factory calibrated
Prepared for oil lubrication
Product description
Page 99289A_200-594e-07.21
3.3 Application
Typical areas of use are measurements of tire characte-
ristics on tire test stands in the laboratory as well as on
mobile test vehicles in the elds of durability, non-unifor-
mities, vibrations, braking characteristics, adhesion etc.

4. Installation
Measuring hubs of Type 9289A2x3 are precision instru-
ments and must be handled carefully. Please take note of
the following:
Do not drop the measuring hub or expose it to any
hard knocks! The maximum force of such shocks could
exceed the measuring range of the instrument and
cause severe damage
Do not use a hammer for positioning the rim adapter,
since hammer blows can cause deformation of the
bearings or rim
In the following chapters, you will nd information on ins-
talling the measuring hub and basic details for setting up
the test rig.

4.2 Mounting the measuring hub on the test stand
Please comply with the following notes for correct
mounting of the measuring hub:
The measuring hub must be installed only by qualied
persons who are familiar with devices of this type
Before mounting the measuring hub on a test stand or
another test device, check that the mounting surface
is at and clean. Uneven and dirty contact surfaces
cause internal distortions, which will expose the indi-
vidual force sensors to additional high stress, which
could reduce the accuracy
Before mounting the measuring hub on a test stand or
another test device, connect the oil hoses as explained
in chapter 5 and mount all additional equipment on the
shaft rear side such as resolver, slip ring, brake disc…
Depending on the accessibility to the test stand, cables
can also be connected in advance
Ensure accuracy and cleanliness in all work involving
electrical connections. Do not remove the cover caps
from the connections until immediately before connect-
ing a cable
Before connecting the cable to the measuring hub
clean both sides of the connector (measuring hub and
cable) with the cleaning and insulation spray Type
1003. Check orientation and plug in the cable until a
proper contact is made
