Abstract
L'invention concerne un système de régulation d'un frein hydrodynamique, notamment de véhicules automobiles. Ledit système, qui englobe au moins une boîte de vitesses 6, un frein hydrodynamique 7, son organe de réglage asservi A, une source d'énergie 1 et un organe de réglage manuel 9 monté dans le conduit de commande 4 entre la source 1 et l'organe A, assure le déclenchement de dosages d'énergie proportionnellement au changement de vitesse pour modifier proportionnellement la course de l'organe asservi A en fonction d'un organe de manoeuvre réglable 10 présentant un piston ayant autant de gradins que la boîte de vitesses 6 a de rapports en marche avant et coopérant avec un tringlage 5 de commande de la boîte 6. Application aux transmissions de véhicules automobiles, notamment de véhicules utilitaires.The invention relates to a system for regulating a hydrodynamic brake, in particular for motor vehicles. Said system, which includes at least one gearbox 6, a hydrodynamic brake 7, its servo-controlled adjustment member A, a source of energy 1 and a manual adjustment member 9 mounted in the control duct 4 between the source 1 and member A, ensures the triggering of energy dosages proportional to the change of speed to proportionally modify the stroke of the slave member A as a function of an adjustable actuator 10 having a piston having as many steps as the gearbox gears 6 has forward gears and cooperating with a control linkage 5 of the gearbox 6. Application to transmissions of motor vehicles, in particular of utility vehicles.
