Description
Einrichtung zur sicheren Handhabung des Umschalters eines auf das Fahr-oder Arbeitsgetriebe arbeitenden elektrischen Notors. Die Erfindung bezieht sich auf- elektrische Fahrzeuge, bei welchen, der Motor nicht nur auf das Fahrgetriebe, sondern auch auf Antriebsmechanismen von auf dem Fahrzeug angeordneten Arbeitsmaschinen, wie z. B. Windwerke, Krane, Kipper USW., geschaltet werden kann. Die Erfindung besteht im wesentlichen darin, eine Einrichtung vorzusehen, welche die falsche Handhabung der Schaltvorrichtung verhütet, indem das Umschaltorgan für die Getriebe in jeder seiner Stellungen die elektrische Schaltvorrichtung bzw. das Betätigungsgestänge für den Kon:troller derart beeinflußt, @daß eine Änderung der Getriebeschaltung erst nach Abstellung des Motors möglich ist.Device for safe handling of the changeover switch of an electric motor operating on the drive or work gear. The invention relates to electric vehicles in which the engine not only affects the drive transmission, but also the drive mechanisms of working machines arranged on the vehicle, such as. B. winches, cranes, tippers, etc., can be switched. The invention consists essentially in providing a device which prevents incorrect handling of the switching device by the switching element for the transmission in each of its positions, the electrical switching device or the actuating linkage for the controller influencing @ that a change in the transmission circuit is only possible after the engine has been switched off.
In der Zeichnung ist ein Ausführungsbeispiel der Einrichtung schematisch dargestellt. Die drehbare Scheibe i ist an ihrem Umfang mit bestimmten Ausschnitten versehen, derart, daß in der Stellung I einer dieser Ausschnitte vor der Nase des um den Bolzen a schwingenden Hebels 3 steht. Die an der Scheibe i angelenkte Zugstange 13 hat hierbei den Motor auf das Fahrgetriebe gekuppelt. Tritt der Führer das Fahrpedal 8 nieder, so wird mittels der Stange 6 die Scheibe i in der Stellung I durch Zusammenwirkender Hebelnase mit dem Scheibenausschnitt gesperrt, und gleichzeitig wird durch die Stange i i die Fahrgetriebebremse gelüftet. Ebenso wird durch den Verbindungshebel 9 und die Stange io der Kontroller freigegeben, so daß das Fahrzeug in Bewegung gesetzt werden kann.In the drawing, an embodiment of the device is shown schematically. The rotatable disk i is provided with certain cutouts on its circumference, such that in position I one of these cutouts is in front of the nose of the lever 3 swinging about the bolt a. The drawbar 13 , which is linked to the disk i, has coupled the motor to the drive gear. If the driver depresses the accelerator pedal 8, the disk i is locked in position I by means of the rod 6 by the interaction of the lever nose with the disk cutout, and at the same time the drive transmission brake is released by the rod ii. Likewise, the controller is released by the connecting lever 9 and the rod io, so that the vehicle can be set in motion.
Ein Niedertreten des Arbeitspedales 7 ist nicht möglich, da die Nase ¢ eines um den Bolzen a schwingbaren und mit dem Pedal 7 durch die Stange 5 verbundenen Hebels an dem Umfang der Scheibe i anliegt.Stepping down on the work pedal 7 is not possible because the nose One that can swing around the bolt a and is connected to the pedal 7 by the rod 5 Lever rests against the circumference of the disk i.
Das Umschalten des Motors vom Fahrgetriebe auf das Arbeitsgetriebe kann nur nach Freigeben des Pedales 8 erfolgen, wodurch der Motor abgestellt und das Fahrgetriebe gebremst wird. Wird hierauf die Scheibe i in die Stellung II gedreht, so erfolgt die Kupplung des Motors mit dem Arbeitsgetriebe, und erst dann kann das Pedal 7 wieder getreten werden. Hierbei tritt die Nase q. in den zweiten Ausschnitt der Scheibe i, es wird die Bremse des Arbeitsgetriebes durch :die Stange i? gelüftet und der Kontroller ebenfalls durch die Stange io freigegeben. Eine Betätigung des Pedales 8 ist unmöglich, da die Nase des Hebels 3 dem Umfang der Scheibe gegenübersteht.Switching the engine from the driving gear to the working gear can only be done after releasing the pedal 8, whereby the engine is switched off and the drive gear is braked. If the disk i is then turned into position II, this is how the motor is coupled to the working gear, and only then can that Pedal 7 can be stepped on again. Here the nose occurs q. in the second section the disk i, it becomes the brake of the working gear through: the rod i? ventilated and the controller also released by the bar io. An actuation of the Pedals 8 is impossible because the nose of the lever 3 faces the circumference of the disc.
Der Verbindungshebel 9 ist an den beiden Pedalen 7 und 8 gelenkig befestigt, so daß beim Niedertreten eines jeden Pedales diese Querstange 9 sich um ihren mit dem andern Pedal gegebenen Gelenkpunkt verschwenkt. Durch Verlegen des Befestigungspunktes der Stange io nach rechts oder links auf dem Verbindungshebel 9 ist es daher möglich, einen verschiedenen Hub der Stange io bei gleichbleibender Betätigung der beiden Pedale 7 oder 8 zu erreichen. Damit kann man das Maß der Freigabe des Kontrollers für den einen oder anderen Antrieb beliebig regeln.The connecting lever 9 is articulated on the two pedals 7 and 8 attached, so that when you step down each pedal this crossbar 9 is pivoted about its pivot point given with the other pedal. By embarrassing the fixing point of the rod io to the right or left on the connecting lever 9 it is therefore possible to have a different stroke of the rod io while maintaining the same Actuation of the two pedals 7 or 8 to achieve. This allows you to set the level of release of the controller for one or the other drive.
