Device (D) comprising two identical assemblies (E) joined by means of a linking arm (10) which is provided with ballast means (7) so that the center of gravity (G) of the loaded device is situated under the straight line (ZZ') joining the rotation centers (O) of the two assemblies (E). Means for rotating the device impart, at its center of gravity (G), a cycloidal motion until a predetermined anglular position is obtained which is maintained by appropriate means. Application of at least two devices (D) for implementing methods of comparative measurements of rolling resistances and grip limits of a least two sets of tires, or of at least two types of ground surfaces.
Dispositif (D) concernant deux ensembles montés (E) identiques, assemblés par un bras de liaison (10) qui est pourvu de moyens de lestage (7) tels que le centre de gravité (G) du dispositif chargé soit focalisé sous la droite (ZZ') joignant les centres de rotation (0) des deux ensembles (E). Des moyens de mise en rotation du dispositif confèrent à son centre de gravité (G) un mouvement cycloïdal jusqu'à obtention d'une position angulaire déterminée qui est maintenue à l'aide de moyens appropriés. Application d'au moins deux dispositifs (D) pour la mise en oeuvre de méthodes de mesures comparatives de résistances au roulement et de limites d'adhérence, d'au moins deux trains de pneumatiques, ou d'au moins deux types de sols.
