Description

Die Erfindung betrifft eine Steuerung für einen Boots­antrieb mit einem Motor und einem Verstellpropeller, dessen Flügelsteigung mit Hilfe eines hydraulischen Stelltriebes verstellbar ist, wobei den Arbeitsräumen des Stelltriebes von einem Stellorgan betätigbare Ven­tile zugeordnet sind.The invention relates to a control for a boat drive with a motor and an adjustable propeller, the pitch of which is adjustable with the aid of a hydraulic actuator, wherein the working spaces of the actuator are assigned valves which can be actuated by an actuator.

Bei einem bekannten Bootsantrieb dieser Gattung (EP 01 54 954) ist das Stellorgan ein Stellhebel am Führerstand des Bootes, der den hydraulischen Stell­trieb bzw. dessen Ventile betätigt. Da Bootsantriebe mit einem Motor und Verstellpropeller empfindliche Systeme sind, deren schadensfreier Betrieb vom Boots­führer Erfahrung verlangt, ist nach einem noch nicht zum Stand der Technik gehörenden Vorschlag (DE 39 01 137) auch eine Regelung vorgeschlagen worden. Eine solche Regelung ist jedoch konstruktiv und schaltungstechnisch aufwendig sowie damit teuer. Reparatur und Wartung können nur in qualifizierten Werkstätten durchgeführt werden.In a known boat drive of this type (EP 01 54 954), the actuator is an adjusting lever on the driver's cab of the boat, which actuates the hydraulic actuator or its valves. Since boat drives with a motor and variable-pitch propeller are sensitive systems, the damage-free operation of which requires experience from the boat operator, a regulation has also been proposed according to a proposal that is not yet state of the art (DE 39 01 137). However, such a control is structurally and technically complex and therefore expensive. Repairs and maintenance can only be carried out in qualified workshops.

Aufgabe der Erfindung ist es, eine konstruktiv und schaltungstechnisch einfache sowie leicht bedienbare Steuerung für einen Bootsantrieb mit Verstellpropeller anzugeben, die auch gegen Fehlbedienungen sicher ist.The object of the invention is to provide a constructionally and circuit-technically simple and easy-to-use control for a boat drive with variable pitch propeller, which is also safe against incorrect operation.

Diese Aufgabe wird dadurch gelöst, daß die Ventile als Magnetventile ausgebildet sind, denen jeweils ein vom Stellorgan betätigbares Zeitrelais vorgeschaltet ist, und daß der Motor einen Drehzahlmesser aufweist, der bei Überschreiten einer bestimmten Motordrehzahl das Zeitrelais des für die Vergrößerung der Flügelsteigung verantwortlichen Magnetventils betätigt. Insbesondere soll der Drehzahlmesser bei Überschreiten der Höchst­drehzahl des Motor das Zeitrelais betätigen. Mit die­ser Steuerung kann der Bootsführer die Flügelsteigung des Verstellpropellers bei allen Betriebszuständen durch Betätigung des Stellorgans nach Wunsch verändern. Dabei genügt es, das Stellorgan, welches Taster oder einen Wippschalter aufweisen kann, kurz anzutippen, um die gewünschte Verstellung der Flügelsteigung im Sinne einer Vergrößerung oder einer Verkleinerung auszulösen. Eine Veränderung der Flügelsteigung um 1/2 bis 1° bei Betätigung des Stellorgans hat sich als zweckmäßig erwiesen. Das kann mit einer Einschaltdau­er der Zeitrelais von 50 bis 200 mm/sec erreicht wer­den.This object is achieved in that the valves are designed as solenoid valves, each of which is preceded by a time relay which can be actuated by the actuator, and in that the motor has a tachometer which when a certain engine speed is exceeded, the time relay of the solenoid valve responsible for increasing the wing pitch is actuated. In particular, the tachometer should actuate the timing relay when the maximum engine speed is exceeded. With this control, the operator can change the pitch of the variable pitch propeller in all operating conditions by actuating the actuator as required. It is sufficient to briefly touch the actuator, which may have a button or a rocker switch, to trigger the desired adjustment of the wing pitch in the sense of an enlargement or a reduction. A change in the wing pitch by 1/2 to 1 ° when actuating the actuator has proven to be useful. This can be achieved with a duty cycle of 50 to 200 mm / sec.

Da jedoch bei jeder Veränderung der Flügelsteigung auch der Motor mit einer Vergrößerung oder Verringe­rung seiner Drehzahl reagiert und ein Überdrehen des Motors zu schweren Schäden führen kann, besitzt der Motor einen Drehzahlmesser, der bei Überschreiten der Höchstdrehzahl des Motors das Zeitrelais des für die Vergrößerung der Flügelsteigung verantwortlichen Magnetventils betätigt. Auch wenn der Bootsführer versuchen sollte, im Bereich der Höchstdrehzahl des Motors die Flügelsteigung des Verstellpropellers zu verringern, wird stets bei Erreichen der Höchstdreh­zahl die Flügelsteigung wieder vergrößert, so daß die Motordrehzahl z.B. um einen Betrag von 300 U/min ab­sinkt.However, since every time the wing pitch changes, the engine reacts by increasing or decreasing its speed and over-revving the engine can cause serious damage, the engine has a tachometer that, when the maximum engine speed is exceeded, the timing relay for increasing the wing pitch responsible solenoid valve actuated. Even if the operator tries to reduce the pitch of the variable-pitch propeller in the area of the maximum engine speed, the wing pitch is increased again when the maximum speed is reached, so that the engine speed drops, for example, by an amount of 300 rpm.

Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; die ein­zige Figur zeigt schematisch die Steuerung für einen Bootsantrieb mit einem Motor 1 und einem Verstell­propeller 2. Der Motor 1 ist ein Verbrennungsmotor, der über eine Welle 3 den Verstellpropeller 2 antreibt. Der Verstellpropeller 2 besitzt einen darin integrier­ten hydraulischen Stelltrieb, der über eine nicht dar­gestellte Verstellmechanik die Propellerflügel 4 ver­stellt. Jedem Arbeitsraum des hydraulischen Stelltrie­bes ist jeweils ein Magnetventil 5 bzw. 6 zugeordnet, welches den Zufluß zum jeweiligen Arbeitsraum steuert. Die Magnetventile 5, 6 werden ihrerseits gesteuert von Zeitrelais 7, 8, welche von elektrischen Impulsen eines Wippschalters 9 ausgelöst werden.In the following an embodiment of the invention shown in the drawing is explained; the only figure shows schematically the control for a boat drive with a motor 1 and a variable propeller 2. The motor 1 is an internal combustion engine which drives the variable propeller 2 via a shaft 3. The adjusting propeller 2 has a hydraulic actuator integrated therein, which adjusts the propeller blades 4 via an adjusting mechanism (not shown). Each working area of the hydraulic actuator is assigned a solenoid valve 5 or 6, which controls the inflow to the respective working area. The solenoid valves 5, 6 are in turn controlled by time relays 7, 8, which are triggered by electrical pulses from a rocker switch 9.

Bei Betätigung des Zeitrelais 7 öffnet das Magnetven­til 5 für eine bestimmte Zeit, z.B. 50 - 200 mm/sec, und die Flügelsteigung der Propellerflügel 4 wird um 1/2 bis 1° verringert. Bei Betätigung des Zeitrelais 8 öffnet das Magnetventil 6,und die Flügelsteigung der Propellerflügel 4 wird um einen entsprechenden Betrag vergrößert.When the time relay 7 is actuated, the solenoid valve 5 opens for a certain time, e.g. 50 - 200 mm / sec, and the pitch of the propeller blades 4 is reduced by 1/2 to 1 °. When the time relay 8 is actuated, the solenoid valve 6 opens and the pitch of the propeller blades 4 is increased by a corresponding amount.

Als Sicherheit gegen Überdrehen des Motors 1 ist ein die Motordrehzahl erfassender Drehzahlmesser 10 vorge­sehen, der bei Überschreiten der Höchstdrehzahl des Motors 1 ein Signal an das Zeitrelais 8 abgibt, so daß dieses ausgelöst wird und das zugeordnete Magnet­ventil 6 aufsteuert, womit die Flügelsteigung der Propellerflügel 4 vergrößert wird. Als Folge davon sinkt die Motordrehzahl um einen entsprechenden Betrag.As a safeguard against overturning the engine 1, a tachometer 10 which detects the engine speed is provided, which emits a signal to the timing relay 8 when the maximum speed of the engine 1 is exceeded, so that this is triggered and activates the associated solenoid valve 6, thus increasing the pitch of the propeller blades 4 is enlarged. As a result, the engine speed drops by a corresponding amount.
