  • the width direction dimension of the protective sheet 19 is equal to the width direction dimension W of the endless belt 14, and the outer peripheral surface 14 o of the endless belt 14 is covered by the protective sheet 19 over substantially the entire circumference.
  • the outer peripheral surface 14o is protected so that the outer peripheral surface 14o of the endless belt 14 is not damaged by contact with the edge roller 13 '. It is protected by the sheet 19. For this reason, deformation such as warping of the endless belt 14 caused by scratches on the outer peripheral surface 14o of the endless belt 14 is prevented.
  • the bending rigidity required for the protective sheet 19 is the same as that required for the protective sheet 17 provided on the inner peripheral surface 14 i of the endless belt 14. That is, it is sufficient that the bending rigidity of the endless belt 14 is sufficiently larger than that of the protective sheet 19.
  • the ratio of the bending rigidity of the endless belt 14 to the protective sheet 19 may be 10 or more, and more preferably 100 or more.
  • the automobile C is used as a test body, but the present invention is not limited to the above configuration. That is, a moving belt mechanism used in a vehicle other than a vehicle (for example, a vehicle that does not use a prime mover, a mock-up model for evaluating aerodynamic characteristics of a vehicle), an aircraft, or a test apparatus using a vehicle wheel or a suspension alone as a test body. Is also included in the moving belt mechanism for a running test apparatus according to an embodiment of the present invention.

Abstract

L'invention concerne un mécanisme de déplacement de courroie pour dispositif d'essai mobile, et une courroie sans fin. Le mécanisme de déplacement de courroie pour dispositif d'essai mobile possède une courroie sans fin qui est enroulée autour d'un rouleau de correction de méandres destiné à corriger les méandres de ladite courroie sans fin par inclinaison autour d'un axe perpendiculaire à l'axe de rotation. Une feuille de protection côté périphérique interne destinée à protéger sensiblement toute la surface périphérique interne de la courroie sans fin, est posée sur la surface périphérique interne de la courroie sans fin, ladite courroie sans fin présentant une rigidité à la flexion suffisante de manière à ne pas se déformer sous la contrainte qui est exercée de manière que la courroie sans fin soit courbée du fait de la distorsion de la feuille de protection côté périphérique interne.
