Definitions

  • the invention relates to a hybrid drive train of a motor vehicle, comprising a serial arrangement of an internal combustion engine, a first operated as a generator first electric machine, a predominantly operable as an electric second electric machine, and a final drive, and with a switchable via lines and power electronics with the two electric traction battery and a controller for controlling the flow of energy between the electric machines and the driving battery.
  • a hybrid powertrain of a motor vehicle is understood to mean a drive train with a hybrid drive, which consists of a combination of an internal combustion engine and an electric motor, wherein the electric motor can be supplied either from an entrained running battery or from a contact wire via current collectors.
  • a hybrid drive which consists of a combination of an internal combustion engine and an electric motor, wherein the electric motor can be supplied either from an entrained running battery or from a contact wire via current collectors.
  • a parallel hybrid drive which is known for example from DE 102 48 715 A1 and DE 101 58 536 B4
  • the internal combustion engine and the electric motor in parallel arrangement on the final drive are effective, i. the motor vehicle in question can be driven either directly by the internal combustion engine or the electric motor or jointly by both drive motors.
  • a disadvantage of this design is that for start-up and driving with the engine, a starting clutch and a driving gear is required, resulting in a large space requirement and high weight of the drive train.
  • the internal combustion engine drives a generator via which, in conjunction with a traction battery, an electric motor connected to the final drive is fed.
  • the direct drive of the motor vehicle thus always takes place via the electric motor, wherein the internal combustion engine but if necessary, for. B. when driving on inner city areas with emission restrictions, can be turned off, so that the electric motor is then fed only from the drive battery.
  • An advantage of this design is that a starting clutch and a driving gear are not required and can be saved, resulting in a low space requirement and a low weight of the drive train l results.
  • a disadvantage of this design is the two-fold energy conversion mechanical-electrical and electrical-mechanical between the engine, the generator, and the electric motor, resulting in a relatively poor efficiency result.
  • the electric motor is usually operated at higher speeds in an unfavorable operating range.

La présente invention concerne une chaîne de transmission hybride de véhicule automobile comprenant, disposés en série, un moteur à combustion interne, une première machine électrique pouvant fonctionner principalement comme générateur, une seconde machine électrique pouvant fonctionner principalement comme moteur électrique, et un entraînement d'essieux, et comprenant une batterie qui peut être reliée aux deux machines électriques par des lignes commutables et un système électronique de puissance, ainsi qu'un dispositif de commande pour commander le flux énergétique entre les machines électriques et la batterie. Afin d'obtenir des dimensions compactes et un rendement amélioré, les deux machines électriques se présentent sous la forme d'un mécanisme électromagnétique (6) comprenant un rotor d'entraînement d'entrée (7) monté rotatif et relié à un arbre d'entrée, un rotor d'entraînement de sortie (8) monté rotatif et relié à un arbre de sortie, et un stator (9) commun monté pour pouvoir effectuer un mouvement axial et relié fixement à une partie de boîtier. Selon l'invention, le rotor d'entraînement d'entrée (7) et le rotor d'entraînement de sortie (8) présentent respectivement des animants permanents à polarité alternée, répartis en périphérie, disposés de façon cylindrique selon un voisinage axial, et le stator (9) présente au moins un enroulement de court-circuit qui est disposé selon un voisinage axial par rapport aux aimants permanents des rotors (7, 8), et qui est relié à un système électronique de puissance associé (13), le rapport de transmission efficace pouvant être réglé par un déplacement axial du stator (9) par rapport aux rotors (7, 8).
