Abstract

Transmission hydromécanique à plusieurs modes de fonctionnement Elle comprend deux engrenages planétaires ayant chacun une roue planétaire, un frein et un embrayage associé à ces engrenages et destiné à établir, avec le frein, les différents modes de fonctionnement de la transmission Cette dernière est associée à une tranmission hydrostatique qui comprend un élément à culindrée fixe et un autre élément à cylindrée variable. Domaine d'application : véhicules et autres machines à moteur.Hydromechanical transmission with several operating modes It comprises two planetary gears each having a planetary wheel, a brake and a clutch associated with these gears and intended to establish, with the brake, the various operating modes of the transmission.The latter is associated with a Hydrostatic transmission which comprises a fixed cylinder head element and another variable displacement element. Field of application: vehicles and other motor machinery.
