Die Erfindung betrifft eine Kabelaufwickelvorrichtung für das Anschlusskabel eines mit einem elektromotorisch angetriebenen Schneidwerkzeug ausgestatteten Rasenmähers.The invention relates to a cable winding device for the connecting cable of a cable driven by an electric motor Cutting tool equipped lawn mower.
Bei einer bekannten Ausbildung einer Kabelaufwickelvorrichtung wird das Gegendrehmoment des drehbar am Fahrgestell des Rasenmähers gelagerten Antriebsmotorgehäuses zum Aufwickeln des Änschlußkabels auf einer mit dem Motorgehäuse fest verbundenen Kabeltrommel ausgenutzt, wobei jedoch um ein genügend großes Gegendrehmoment zu erhalten an der Motorwelle eine Bremse beispielsweise in Form eines Windflügelrades vorgesehen ist. Bei dieser Ausbildung ist nachteilig, daß nicht die gesamte Motorleistung zum Schneiden des Grases zur Verfügung steht, sondern nur eine, um die vom Windflügelrad verbrauchte Bremsleistung verminderte Leistung. Ferner machen sich auch die Luftgeräusche des Windflügelrades nachteilig bemerkbar.In a known embodiment of a cable winder, the counter torque of the rotatable on the chassis of the lawnmower mounted drive motor housing for winding the connection cable on a firmly connected to the motor housing Cable drum exploited, but in order to obtain a sufficiently large counter-torque on the motor shaft, for example, a brake is provided in the form of a wind vane. The disadvantage of this design is that not the entire engine power is available for cutting the grass, but only one to reduce the braking power consumed by the wind vane wheel decreased performance. Furthermore, there are also air noises of the wind impeller disadvantageously noticeable.

Ferner sind diese Antriebsmotore derart ausgelegt, daß sie für alle Betriebszustände des Hasenmähers ein Drehmoment auf die Kabeltrommel ausüben, welches zum sicheren Aufrollen des Anschlußkabels 4 bzw. 34 ausreicht. Derartige kurzschlußfeste Motoren erleiden auch dann keinen Schaden, wenn sie über längere Zeit blockiert werden, was beispielsweise dann auftritt, wenn der Rasenmäher nicht bewegt wird.their capacitor capacity can be controlled. Furthermore, these drive motors are designed in such a way that they exert a torque on the cable drum for all operating states of the hare mower, which torque is sufficient to safely roll up the connecting cable 4 or 34. Such short-circuit-proof motors also suffer no damage if they are blocked for a long time, which occurs, for example, when the lawnmower is not moved.
