Title: (DE) FAHRZEUG MIT ZWEI ACHSEN.
(EN) TWIN-AXLE VEHICLE
(FR) VEHICULE A DEUX ESSIEUX.
Abstract: front page image
(DE) Es wird ein Hybridauto vorgeschlagen, dessen Brennkraftmaschine die eine Achse antreibt, während der Elektromotor einer zweiten Achse zugeordnet ist. Zur Aufrechterhaltung der Servofunktion ist im Bereich der Brennkraftmaschine ein weiterer Elektromotor vorgesehen, der bei Elektrobetrieb die Servopumpe betätigt.
(EN) Proposed is a hybrid-propulsion vehicle one of whose axles is driven by an internal-combustion engine while the other is driven by an electric motor. A second electric motor mounted in the vicinity of the internal-combustion engine acts as a servo motor, operating a servo pump when the vehicle is running on electric drive.
(FR) L'invention propose une automobile hybride dont le moteur à combustion interne entraîne un essieu tandis que le moteur électrique est affecté à un deuxième essieu. Pour maintenir la fonction assistée, on prévoit un autre moteur électrique dans la zone du moteur à combustion interne, qui actionne, en fonctionnement électrique, la pompe de conduite assistée.
