HT-2811T3 Tire and Rim Endurance HighSpeed Rotatable Drum Testing Machine
A. Testing purpose
Conforming to the standard of SAE J2562, much closer to the real running condition of road
wheels, in order to understand its feature of endurance.
B. Testing Requirements
4. Inside drum test:
Suitable wheel: O.D. 500~800mm x W100~220mm
Suitable rim: 12″ ~ 17″ with testing tyre
Remarks: According to the standard of SAE J2562, the tire outside diameter is within 50%
to 80% of the drum internal diameter. The diameter of the drum is 1000 mm, so the suitable
range of wheel diameter is within 500~660 mm, or we can manufacturer as per your special
requests.
» According to the standard of SAE J2562 (Biaxial Wheel Fatigue test) , The tire-wheel
assembly can be tested by radial load only, or radial load and lateral load simultaneously.
Camber angel can be adjusted freely and be convenient for moutning different sizes of wheel
samples. For maximum loading, itis:
Radial loading: 0~20 kN
Axial loading: 0~15 kN
C. Functional parameters
