Abstract
L'invention concerne le secteur technique des transmissions hydrostatiques de puissance. Le récepteur hydraulique selon l'invention est caractérisé en ce qu'il comprend au moins un moteur à cylindrée fixe 1 alimenté par une pompe 4 et des moyens hydrauliques 3 de variation uniforme du couple et de la vitesse du récepteur, liés au moteur à cylindrée fixe par un moyen mécanique 5, 6. L'invention est applicable à tout véhicule à roues ou à chenilles de forte puissance nécessitant un fonctionnement sans à-coups et pour lesquels des impératifs de poids et de volume stricts sont imposés.
