Abstract

A.DISPOSITIF DE MESURE OPTIQUE DU COUPLE DE ROTATION AGISSANT SUR UN TRONCON DEFINI D'UN ARBRE, NOTAMMENT POUR COMMANDER LA BOITE DE VITESSE AUTOMATIQUE D'UN VEHICULE AUTOMOBILE. B.DISPOSITIF CARACTERISE EN CE QU'A CHAQUE EXTREMITE DU TRONCON D'ARBRE E EST DISPOSE L'UN DES DEUX DISQUES 2, 3 EN SAILLIE TRANSVERSALEMENT A L'ARBRE 1, CES DISQUES ETANT MUNIS D'UNE TRAME DE LIGNES RADIALES FAISANT LE MEME ANGLE EN DIRECTION PERIPHERIQUE, LES LIGNES DE TRAME 11 A 18; 21 A 28 DE L'UN DES DEUX DISQUES ETANT DECALEES D'UN PETIT ANGLE A INFERIEUR A 15, NOTAMMENT COMPRIS ENTRE 3 ET 10, PAR RAPPORT AU CENTRE A DU DISQUE. C.DISPOSITIF APPLICABLE A LA MESURE DE LA TORSION D'UN ARBRE DE SORTIE DE BOITE DE VITESSES DE VEHICULE AUTOMOBILE.A. DEVICE FOR OPTICAL MEASURING OF THE ROTATION TORQUE ACTING ON A DEFINED SECTION OF A SHAFT, IN PARTICULAR FOR CONTROL OF THE AUTOMATIC GEARBOX OF A MOTOR VEHICLE. B. DEVICE CHARACTERIZED IN THAT AT EACH END OF THE TREE TRUNK E IS PROVIDED WITH ONE OF THE TWO DISCS 2, 3 projecting transversely from SHAFT 1, THESE DISCS BEING EQUIPPED WITH A WEFT OF RADIAL LINES MAKING THE SAME ANGLE IN PERIPHERAL DIRECTION, WEFT LINES 11 TO 18; 21 TO 28 OF ONE OF THE TWO DISCS BEING OFFSET FROM A SMALL ANGLE TO LESS THAN 15, IN PARTICULAR BETWEEN 3 AND 10, FROM THE CENTER A OF THE DISC. C. DEVICE APPLICABLE TO MEASURING THE TORSION OF A MOTOR VEHICLE GEARBOX OUTPUT SHAFT.
