Description

Bei diesel- oder benzinelektrischen Fahrsbaplern ist ein Gaspedial vorhanden, mit dem der Motor sowohl beim Fahren als auch ,beim. Stapeln, bei dem er als Antrieb für,die. hydran lische Preßpumpe, dient, ;geregelt wird.There is an accelerator pedal on diesel or gasoline-electric truck trucks available, with which the engine both when driving and when. Stacking where he as a drive for that. hydraulic press pump, serves,; is regulated.

Ein vorzugsweise am Lernkrad angeordneter Hebel i dient der Bestimmung der Fahrtrichtung; er überträgt :seine Bewegung mittels einer Welle 9 auf die nicht dargestellten Steuerglieder für die Umschaltung der Fahrtrichtung und hat eine Mittelstellung, in der das Fahrzeug weder vorwärts noch rückwärts fahren kann.A lever i, which is preferably arranged on the Lernkrad, is used for the determination the direction of travel; he transmits: his movement by means of a shaft 9 to the not shown control elements for switching the direction of travel and has a central position, in which the vehicle can neither go forwards nor backwards.

Es muß verhindert werden., daß dieser Hebel aus der Mittelstellung, also der Nullstellung, @in eine Fahrstellung gebracht werden kann, während bei stillstehendem Fahrzeug der Motor lediglich zum Antrieb der dem Hub dienenden Preßpumpe betätigt wird.It must be prevented that this lever moves out of the middle position, So the zero position, @ can be brought into a driving position, while at a standstill Vehicle actuated the engine only to drive the press pump serving the stroke will.

Diesem Zweck dient die Blockiervorrichtung nach der Erfindung.The blocking device according to the invention serves this purpose.

Auf der Welle 3 des- Gaspedals 2 ist ein Hebel q. starr angebracht. Auf ihr ist außerdem ein Hebel 5 :schwenkbar gelagert, der durch eine Federkraft, beispielsweise durch eigne Schraubenfeder 6, geigen den: Hebel q. gezogen odergedrückt wird.On the shaft 3 of the accelerator pedal 2 is a lever q. rigidly attached. On it is also a lever 5: pivotably mounted, which by a spring force, for example by using its own coil spring 6, violin the: lever q. pulled or pushed will.

Der Hebel 5 weist eine Raste 7 auf, in die ein mit der Welle 9 des Fahrtrichtungswählers verbundener Nocken 8 einrastet, wenn der Hebel i des Fahrtrichtungswählers in der Mittel-, also. in dein Nullstellung steht und dias Gaspedal 2 niedergetreten ist. Sobald ,das Gaspedal losgelassen wird, der Motor also seine Leerlaufdrehzahl annimmt, dreht sich die Welle 3 im. Richtung- des in Fig. i angegebenen Pfeiles und .hebt den starr mit ihr verbundenen: Hebel q., :der unter eine am Hebel 5 angeordnete Nase io greift und übear diese auch dien Hebel 5 so weit hebt, daß die Raste 7- den. Nocken 8 freigibt und der Fahrtrichtungswähler durch Drehen, der Welle 9 .in eine Fahrstellung gebracht werden kann. Dabei nimmt der Nocken 8 dann bei-. spiels:weise die .in Fig. 2 dargestelke Stellung ein, und das Gaspedal 2 kann zur Geschwindigkeitsregelung niedergetreten werden, .da ja der Hebel 5 gegen die Kraft der Feder 6 ausweicht.The lever 5 has a detent 7 into which a shaft 9 of the Direction selector connected cam 8 engages when the lever i of the direction selector in the central, so. is in your zero position and stepped on the accelerator pedal 2 is. As soon as the accelerator pedal is released, the engine is idling assumes, the shaft 3 rotates in. Direction of the arrow indicated in Fig. I and .lifts the: lever q Nose io grips and over this also lifts the lever 5 so far that the catch 7- the. Cam 8 releases and the direction selector, by turning, shaft 9 .in a driving position can be brought. The cam 8 then increases. play: wise the position shown in Fig. 2, and the accelerator pedal 2 can be used for speed control be trodden down, because the lever 5 evades against the force of the spring 6.

Erst wenn bei niedergetretenem Gashebel 2 der Fahrtrichtungswähler reit der Welle 9 geschwenkt wird, rastet der Nocken 8 .bei Mittelstellung des FahrtriehtungswähIlers unter der Wirkung der Feder 6 in .die Raste 7 ein und verhindert eine Fahrtrichtungsumkehr .bei niedergetretenem Gashebel 2. Zum Übergang aus der Nullstellung in die Fahrtrichtungsstellung der Welle 9 muß zwangläufig auf auf diesle Weise vorher stets der Gashebel 2 losgeliassen, also Ader Motor auf Leerlaufdrehzahl abgedrosiselt werden.Only when the travel direction selector is depressed when the throttle lever 2 is depressed When the shaft 9 is pivoted, the cam 8 engages when the travel direction selector is in the middle position under the action of the spring 6 in .the detent 7 and prevents a reversal of the direction of travel .When the throttle lever is depressed 2. To transition from the zero position to the travel direction position the shaft 9 must necessarily always release the throttle lever 2 in this way beforehand, so the engine must be cut off to idle speed.
