 Roller test rig 

Testing tyres under load at very high speeds (e.g. > 300km/h for private cars) and in complete safety is a realistic proposition on this rig consisting of a smooth roller with a diameter of 1.7 m.

Specifications 

 

Test rig for wheels of private cars, motorcycles and bicycles :
  • Roller diameter : 1700 mm.
  • Maximum tyre diameter : 800 mm.
  • Maximum tyre width : 450 mm.
  • Maximum radial load : 1000 daN.
  • Maximum driving speed : >300 km/h.

Test rig for wheels of industrial and agricultural vehicles:

  • Maximum tyre diameter : 1400 mm.
  • Maximum tyre width : 605 mm.
  • Maximum radial load : 8000 daN.
  • Maximum camber : ± 6%.
  • Maximum driving speed : 180 km/h.

Examples of applications 

  • Load – speed tests mentioned in the European regulations R30, R54 and R75.
  • Resistance of retreaded tyres.
  • Endurance of rims according to European regulation R124
  • Comparisons of tyre grip in extreme conditions.
  • Verification of conformity of production.

And by 2010, we will also be evaluating rolling resistance on these types of test rigs !
