3 Terms and definitions
The terms and definitions defined in GB/T 2933 AND the following terms and
definitions apply to this Standard.
3.1
Wheel hub
Part which is located between bearing and spoke of wheel. It usually has brake drum
or can be installed with brake plate and transmission mechanism.
3.2
Spoke
3.3
Spoke nut
Nut used to fix spoke on rim.
3.4
Wire spoke-wheel
Rotating part located between tire and bearing, which is composed of rim, spoke,
spoke nut, and hub.
Figure 1 Measurement Position of Deformation of Back Wheel after Radial
Impact
accordance with 5.7.2, wheel shall be free of damage crack, breakage, and the
abnormal loosen of joint part. The radial and axial circle run-out of wheel after test
shall not be greater than 2.0mm.
4.7.3 Torsion fatigue performance. After test with more than 1×105 rotation in
accordance with 5.7.3, wheel shall be free of damage crack, breakage, and the
abnormal loosen of joint part. The radial and axial circle run-out of wheel after test
shall not be greater than 2.0mm.

5.7.2.2 Test conditions.
a) Radial load.
Radial load Q is determined by formula (5).
Q = Sr × Fv ... (5)
Where.
Q — Radial load, N;
Sr — Intensified test coefficient, 2.25;
Fv — Refer to the definition in 5.7.1.2 c).
the maximum design load, kPa; deviation is ±10 kPa;
c) Radial load fluctuation tolerance. the load fluctuation tolerance during test is
±5%;
d) Tire breakdown. In case of tire breakdown, test shall be continued after tire is
replaced.
5.7.2.3 Test method. Tire shall be installed on the test machine in the same way as it
is installed on the vehicle (refer to Figure 7). Tire is inflated in accordance with the
method in 5.7.2.2 b). Then APPLY the radial load Q according to the calculated value
of Formula (5); at the same time, DRIVE the drum to rotate and then conduct test. All
of drum.
5.7.2.4 CHECK cracks after test is done. For the inspection of cracks, ADOPT visual
inspection method, dye penetration method, penetration flaw detector, or X-ray fault
detector to inspect cracks.
