Title (EN) PROCESS AND DEVICE FOR REGULATING THE DRIVING TORQUE TRANSMITTED BY A TRACTOR TO A HYDRAULICALLY-DRIVEN SEMITRAILER
(FR) PROCEDE ET DISPOSITIF DE REGULATION DU COUPLE MOTEUR TRANSMIS PAR UN TRACTEUR A UNE SEMI-REMORQUE A ENTRAINEMENT HYDRAULIQUE
Abstract: front page image
(EN)In said process, the relation between the fluid pressure and the variation in the ratio, or in the shift, between the speed of the tractor (1) wheels and those of the semitrailer (2) in the hydraulic circuit is defined, said shift is determined and a correction signal proportional to the shift is applied to the capacity of the pump (14) and/or of the hydraulic engine (16) when the fluid pressure is no longer contained in a predetermined range, between a higher and a lower pressure.
(FR)Le procédé consiste essentiellement à définir la relation existant dans le circuit hydraulique (15), entre la pression du fluide et la variation du rapport, ou glissement, entre la vitesse des roues du tracteur (1) et de celles de la semi-remorque (2), à déterminer ce glissement et à agir sur la cylindrée de la pompe (14) et/ou du moteur hydraulique (16), avec un signal de correction proportionnel au glissement, lorsque la pression du fluide sort d'un intervalle prédéterminé, entre une pression supérieure et une pression inférieure.
