Measuring Hub for Tire Test Stands
The RoaDyn P530 measuring hub is the ideal instrument for
measuring the wheel force and torque on tire test stands in
the laboratory as well as on mobile test vehicles. The system
measures the orthogonal forces Fx, Fy, Fz and torques Mx,
My, Mz. It is uniquely suited for the measurement of tire nonuniformity, tire vibration, and tire characteristics.
9295B_000-991e-06.13
• Maximum measuring accuracy during high dynamic testing
• Fits to wheels with rim size 13 inches or larger; smaller rims
may be mounted with a compatible adapter
• Fits to standard rims with interchangeable adapters; custom
rims not required
• Bearings with oil lubrication and cooling for rotational speeds
up to 3 000 min-1 at full load
• Alternative grease lubrication for rotational speeds up to
2 000 min-1 for short running periods available upon request
Description
The RoaDyn P530 measuring hub is a robust, high-precision
instrument equipped with quartz sensors. Four 3-component
force sensors are mounted with high preload between two plates. Inside, a rotating shaft with bearings holds the mounted
wheel in place.
The path-independent measurement of the force components
naturally result in a minimum crosstalk between the components and a resonant frequency of the complete measuring
system. The end of the shaft is lead through the rear side of
the dynamometer and is prepared for connecting a brake or
driving device. It provides an oil circulation for lubrication and
cooling of the bearings, resulting in perpetual heat conditions
even when high loads are applied.
The mechanical interfaces for mounting on the tire test stand
allow front or rear side mounting.
The dynamometer is protected against corrosion, splash water
and dust. The measured signals are transmitted to the charge
amplifier (with summing amplifier) via a robust high-insulation
cable.
Application
• Measurement of force and moment resulting from tire
non-uniformities, even at high speeds (non-uniformity
tests)
• Quasistatic, dynamic and highly dynamic measurements of
tire characteristics
• Tire vibration measurement
• Universal measuring tool for laboratory tire test stands in
the fields of research, development and quality control

Test Stand Connection
Measuring hubs of Type 9295B1 and Type 9295B2 can be
connected at the front side using 3xM16 or 4xM12 screws, or
at the rear side using 8xM16 screws (scope of delivery). Fig. 3
shows the corresponding geometry. When using the 90° angle
plug, an additional slot must be cut (width 25 mm, depth 25
mm, length >80 mm).

Wheel Centering
If the test object is mounted directly on the shaft, it is possible
to mount an additional centering pin on the front side of the
shaft (ø45 H7, 2xM6). This configuration may also be used for
centering an intermediate adapter (see Fig. 5).
Fig. 5: Wheel centering - dimensions
Mounting a Brake
For mounting a brake, the rear side of the measuring hub
provides 8xM12 on a pitch circle of 130 mm (see Fig. 6).

Other Mechanical Interfaces
The shaft provides a through-going bore (M10x1 at the ends),
which can be used for feedthrough of cables or compessed air
(see Fig. 2). It is possible to mount a rotary encoder or a slip
ring for compressed air or additional signals on the rear side of
the shaft (centering ø36 H7, 3xM5 pcd 24 mm).
