Abstract
(DE)
Die vorliegende Erfindung betrifft eine Drehmomentübertragungsanordnung für den Antriebsstrang eines muskelkraftbetriebenen Fahrzeugs mit Hilfsmotor. Die Drehmomentübertragungsanordnung umfasst eine Abtriebswelle, eine erste Eingangswelle zur Übertragung eines mittels Muskelkraft erzeugten Drehmoments auf die Abtriebswelle, einer zweiten Eingangswelle zur Übertragung eines durch den Hilfsmotor erzeugten Drehmoments auf die Abtriebswelle, und eine Freilauffunktion, durch die verhindert wird, dass ein Benutzer des muskelkraftbetriebenen Fahrzeugs den Hilfsmotor mitdrehen muss, wenn der Hilfsmotor ausgeschaltet ist. Erfindungsgemäß ist vorgesehen, dass die Drehmomentübertragungsanordnung eine mechanische Kupplung aufweist, die dazu ausgebildet ist, ein Drehmoment von der zweiten Eingangswelle auf die Abtriebswelle zu übertragen, wenn an der ersten Eingangswelle ein in einer Antriebsdrehrichtung auf die Abtriebswelle wirkendes Drehmoment anliegt, und kein Drehmoment von der zweiten Eingangswelle auf die Abtriebswelle zu übertragen, wenn an der ersten Eingangswelle ein auf die Abtriebswelle wirkendes Drehmoment entgegen der Antriebsdrehrichtung anliegt.

The present invention relates to a torque-transmitting arrangement for the drive train of a muscle-power-operated vehicle with auxiliary motor. The torque-transmitting arrangement comprises an output shaft, a first input shaft for the transmission of a torque generated by muscle power to the output shaft, a second input shaft for the transmission of a torque generated by the auxiliary motor to the output shaft, and a freewheel function, which prevents a user of the muscle-power-operated vehicle from having to concomitantly rotate the auxiliary motor when the auxiliary motor is inactive. According to the invention, it is provided that the torque-transmitting arrangement has a mechanical clutch which is designed to transmit a torque from the second input shaft to the output shaft if, at the first input shaft, a torque prevails which acts in a drive direction of rotation on the output shaft, and to transmit no torque from the second input shaft to the output shaft if, at the first input shaft, a torque prevails which acts on the output shaft counter to the drive direction of rotation.

La présente invention concerne un agencement de transmission de couple pour la chaîne cinématique d'un véhicule à propulsion par la force musculaire doté d'un moteur auxiliaire. Ledit agencement de transmission de couple comprend un arbre de sortie, un premier arbre d'entrée pour transmettre un couple généré au moyen de la force musculaire à l'arbre de sortie, un second arbre d'entrée pour transmettre un couple généré par le moteur auxiliaire à l'arbre de sortie, et une fonction de course libre, au moyen de laquelle un utilisateur du véhicule à propulsion par la force musculaire peut éviter de faire tourner le moteur auxiliaire lorsque le moteur auxiliaire est arrêté. Selon l'invention, ledit agencement de transmission de couple comporte un embrayage mécanique, qui est conçu pour transmettre un couple du second arbre d'entrée à l'arbre de sortie lorsque, au niveau du premier arbre d'entrée, un couple agissant sur l'arbre de sortie dans un sens de rotation d'entraînement est présent et pour transmettre aucun couple du second arbre d'entrée à l'arbre de sortie lorsque, au niveau du premier arbre d'entrée, un couple agissant sur l'arbre de sortie opposé au sens de rotation d'entraînement est présent.
