Description

Es ist bereits bekannt, die Bremsung eines Kraftfahrzeuges, insbesondere bei längerer Talfahrt, entweder zusätzlich zu den vorhandenen mechanischen Bremsvorgängen oder auch für sich allein in der Weise durchzuführen, daß die Brennstoffzufuhr, bei Ottomotoren auch die Zündung, abgestellt und eine im Auspuffrohr angeordnete Klappe geschlossen wird. Der Motor arbeitet dann lediglich als Verdichter der angesaugten Luft, und da die hierzu erforderliche Energie der Bewegungsenergie des Wagens entnommen wird, so tritt eine kräftige Bremswirkung ein, die je nach .dem Gefällegrad zweckmäßigerweise noch durch vorherige Einschaltung eines niederen, im Grenzfalle des ersten Getriebeganges verstärkt wird. Die bisher üblichen Motorbremsen dieser Art sind jedoch insofern noch unvollkommen, als bei ihnen die Möglichkeit besteht, nach ihrer Einschaltung auf einer Gefällestrecke noch eine Gangschaltung auszuführen, und da der Wagen bei einem solchen Versuch vom Motor abgekuppelt werden würde, so würde sich daraus eine äußerst gefährliche Situation ergeben.It is already known, the braking of a motor vehicle, in particular in the case of a long descent, either in addition to the existing mechanical braking processes or to be carried out on its own in such a way that the fuel supply, In the case of gasoline engines, the ignition is also switched off and one located in the exhaust pipe Flap is closed. The engine then only works as a compressor for the intake Air, and since the energy required for this is taken from the kinetic energy of the car a powerful braking effect occurs, which is appropriate depending on the degree of slope by switching on a lower gear, in the limiting case of the first gear is reinforced. The previously common motor brakes of this type are, however, insofar even more imperfect than they can be after they have been switched on to carry out a gear shift on a downhill stretch, and there the car at If such an attempt were to be disconnected from the engine, it would result in a extremely dangerous situation.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diese Gefahr zu beseitigen. Hierzu wird vorgeschlagen, bei einer Bremse der angeführten Bauart eine Sperrvorrichtung anzuordnen, durch die das Auskuppeln bei eingeschalteter Bremse unmöglich gemacht wird.The present invention is based on this risk to eliminate. For this purpose, it is proposed to use a brake of the type mentioned to arrange a locking device through which the disengagement when the brake is on is made impossible.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Unterhalb des Lenkrades i eines Kraftfahrzeuges ist ein Handhebel 2 vorgesehen, mittels dessen eine horizontal an der Stirnwand angeordnete Welle io gedreht werden kann, von der aus über das Hebelgestänge i i, 12 die Klappe 13 im Auspuffrohr 14 der Maschine geschlossen wird, um eine Motorbremsung auszuführen. Auf der Welle io ist außerdem ein Hebel 3 befestigt, mittels dessen bei der Drehung der Welle io über die Stange 4 und ein Gelenk 5 ein unter einem Halter 6 verschiebbar angeordneter Riegel 7 derart verstellt wird, daß der Kupplungsfußhebel 8 nicht niedergedrückt und somit der Motor nicht vom Triebwerk des Kraftfahrzeuges entkuppelt werden kann. Zu diesem Zweck sind seitlich am Fußhebel B Nocken 9 angebracht, unter die sich der Riegel 7 setzt.An embodiment of the invention is shown in the drawing. A hand lever 2 is provided below the steering wheel i of a motor vehicle, by means of which a shaft arranged horizontally on the end wall can be rotated can, from which the flap 13 in the exhaust pipe 14 via the lever linkage i i, 12 the machine is closed to apply engine braking. On the wave io a lever 3 is also attached, by means of which when the shaft is rotated io via the rod 4 and a hinge 5 a displaceably arranged under a holder 6 Latch 7 is adjusted so that the clutch foot lever 8 is not depressed and thus the engine cannot be decoupled from the engine of the motor vehicle. For this purpose, cams 9 are attached to the side of the foot lever B, under which the bolt 7 sets.

Die Sperrvorrichtung wird somit immer gleichzeitig mit der Motorbremse zur Wirkung gebracht, so daß die _ vorstehend geschilderte Gefahr des Motorauskuppelns und damit der Unwirksammachung dieser Bremse beseitigt ist.The locking device is therefore always at the same time as the engine brake brought into effect, so that the _ above-described risk of engine disengagement and thus the ineffectiveness of this brake is eliminated.

Die Erfindung ist nicht auf die dargestellte Ausführungsform beschränkt, sondern umfaßt eine Reihe anderer Bauarten.The invention is not limited to the illustrated embodiment, but includes a number of other types.
