Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009
“Directives for standardization - Part 1: Structure and drafting of standards”.
This standard replaces QC/T 717-2004 “Run out requirements and measuring
methods of automotive wheels”.
As compared with QC/T 717-2004, in addition to editorial changes, the main
technical differences of this standard are as follows:
- CHANGE the standard name into “Road vehicles - Wheels - Requirements
and measuring methods of radial and lateral run-out”;
- MODIFY the requirements for the peak-to-peak value of the runout of
vehicle’s wheel (see clause 3 of the 2004 version; clause 6 of this version);
- ADD definitions of terms such as radial runout, lateral runout, uniformity,
first harmonic, and so on (see clause 3 of this version);
- ADD the principles of measurement (see clause 4 of this version);
- ADD the calculation method for runout (see clause 5 of this version);
- MODIFY the system’s error requirements of the measuring equipment in
the testing method (see clause 4 of the 2004 version; Appendix A of this
version);
- MODIFY the datum of measurement in the testing method (see clause 4 of
the 2004 version; Appendix A of this version);
- DELETE the measurement method for the 15°DC wheels in the testing
method (see clause 4 of the 2004 version; Appendix A of this version);
- MODIFY the Figure A.1, Figure A.2, Figure A.3, Figure A.4 of the testing
method; CHANGE the datum of measurement to the wheel’s mounting
surface (see clause 4 of the 2004 version; Appendix A of this version);
- DELETE the requirement for first harmonics in Appendix A (see Appendix A
of the 2004 version).
This standard uses the redrafting method to modify and adopt ISO 16833:2006
“Road vehicles - Wheels - Requirements and measuring methods of radial and
lateral run-out”.
The technical differences between this standard and ISO 16833:2006 are as
follows:
Road vehicles - Wheels - Requirements and
measuring methods of radial and lateral run-out
1 Scope
This standard defines parameters that characterize the geometric uniformity of
the wheel and describes the principles of measurement of these parameters.
This standard specifies the requirements for the peak-to-peak value of the
radial runout, the peak-to-peak value of the lateral runout, the first harmonic of
the average of radial runout, the first harmonic of the average of lateral runout
of the vehicle wheel.
This standard applies to road vehicle’s wheels of 5°DC, 5°SDC, 5°FB, 15°DC.

3 Terms and definitions
3.1
Radial run-out (RRO)
Over one revolution of the wheel, the amount of change of the distance X of
the rim bead’ seat as relative to the rotation axis of the wheel, in millimeters
(mm), as shown in Figure 1(a).
rim flange as relative to a fixed reference plane perpendicular to the wheel’s
rotation axis
Figure 1 -- Radial runout and lateral runout
3.5
First harmonic
The peak-to-peak value of the fundamental wave of Fourier series.
Note: The frequency of the first harmonic is equal to the frequency of rotation.
3.6
Second (and higher order) harmonic
The peak-to-peak value of the second (or higher order) waveform of the
Fourier series.
4 Principles of measurement
4.1 Datum
4.1.1 Rotation of axis of center-hole-piloted wheel
For the center-hole-piloted wheel, the rotation axis is the center hole’s axis,
which is determined by the axis of the largest inscribed circle and the plane of
the wheel.
4.1.2 Wheel mounting plane
The wheel mounting plane is the plane P (see Figure 2) that supports the hub’s
surface on the wheel plane (the bearing surface of the wheel on the vehicle
hub).
4.1.3 Rotation axis of nut-seat-piloted wheel
For the nut-seat-piloted wheel, the rotation axis is the pitch circle’s axis, which
is determined by the embedded nut seat (see Figure 2).
4.2 Determination of measured values
For each rim bead’s seat, during (one) revolution of the wheel, use a ball which
has a radius of R to be against the rim flange and in constant contact with the
bead’s seat. Through measuring these contact points, determine the measured
values. Unless otherwise stated on the drawing, the radius R of the ball shall
be 8 ± 0.2 mm.
Appendix A
(Informative)
Testing methods of radial and lateral runout of wheel
A.1 Testing equipment
The testing equipment shall have a rotating part equivalent to the positioning of
actual installation of the wheel and a measuring device which facilitate the
runout testing. Equipment’s accuracy meets the following requirements:
a) The system error of the rotating joint component shall meet the
requirements: the radial and lateral runout is less than 0.05 mm.
b) The measuring device is a dial indicator or sensor which has an accuracy
of less than 0.02 mm.
A.2 Datum of measurement
A.2.1 Center-hole-piloted wheel: The datum of measurement is the wheel’s
mounting plane and the center hole.
A.2.2 Bolt-hole-piloted wheel: The datum of measurement is the wheel’s
mounting plane and the nut seat.
A.3 Location of measurement
