Scheibenhandbremse, insbesondere für landwirtschaftlicheDisc hand brakes, in particular for agricultural use

TraktorenTractors

Die Erfindung betrifft eine Scheibenhandbremse für Fahrzeuge, insbesondere für landwirtschaftliche Traktoren, zum Parken oder zur Notbremsung.The invention relates to a disc hand brake for vehicles, in particular for agricultural tractors, for parking or for emergency braking.

Bekannte Scheibenbremsen haben eine Zange, die mit einem Bremsbelag versehene Bremselemente trägt, die mit einer Scheibe in Kontakt bringbar sind, welche sich mit dem zu bremsenden Teil dreht.Known disc brakes have calipers that come with a brake pad provided braking elements which can be brought into contact with a disc, which is with the part to be braked turns.

Die Erfindung will eine Bremse schaffen, die einfach herzustellen ist und deren Zange sich bequem und schnell ausbauen läßt, um die Bremsbeläge der Zange zu erneuern. Die erfindungsgemäße Bremse soll die Verwendung sehr dünner Bremsbeläge ermöglichen, was die Kosten für die Bremse und deren Instandhaltung vermindert.The invention aims to create a brake that is easy to manufacture and the pliers of which can be easily and quickly removed, to replace the brake pads of the caliper. The brake according to the invention should enable the use of very thin brake pads, which reduces the cost of the brake and its maintenance.

Zur Lösung dieser Aufgabe sieht die Erfindung eine Bremse der eingangs erwähnten Art vor, die eine Zange aufweist, die an einer Wand des Getriebekastens des Fahrzeugs gehaltert ist und ein feststehendes Gegenelement und ein bewegliches Element trägt, zwischen welchen eine Scheibe angeordnet ist, die mit einem Nutenring schwimmend gekuppelt ist, welcher auf der Getriebewelle des Fahrzeugs festgekeilt ist, wobei das bewegliche Element der Zange mittels eines Nockens bewegbar ist, derTo solve this problem, the invention provides a brake of the type mentioned at the outset, which has a pair of pliers that are attached to a wall of the gearbox of the vehicle is supported and a fixed counter element and a movable element carries, between which a disc is arranged which is floatingly coupled to a grooved ring which is on the gear shaft of the vehicle is wedged, the movable element of the pliers being movable by means of a cam which

609832/0598609832/0598

auf einer Querwelle sitzt, die über ein Gestänge mit einem Bremshebel verbunden ist.sits on a cross shaft that has a linkage with a Brake lever is connected.

Die erfindungsgemäße Bremse ist von einfacher Konstruktion, bequem zugänglich und leicht ausbaubar, um die Bremselemente oder die Bremsbeläge zu ersetzen.The brake according to the invention is of simple construction, convenient accessible and easily removable to replace the brake elements or the brake pads.

Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der beigefügten Zeichnungen. Darin zeigen:Further details of the invention emerge from the following Description of an exemplary embodiment with reference to the accompanying drawings. Show in it:

Pig. 1 eine Vorderansicht einer erfindungsgemäßen Scheibenhandbremse für landwirtschaftliche Traktoren;Pig. 1 is a front view of a disc hand brake according to the invention for agricultural tractors;

Fig. 2 eine axiale Schnittansicht der Scheibenbremse nach der Linie H-II der Fig.1;Fig. 2 is an axial sectional view of the disc brake according to Line H-II of Figure 1;

Fig.3 eine Seitenansicht in Richtung des Pfeiles III der Fig.2; und3 is a side view in the direction of arrow III of Fig. 2; and

Fig.4 eine axiale Teilschnittansicht in vergrößertem Maßstab einer anderen Ausführungsform der Erfindung.4 is an axial partial sectional view on an enlarged scale another embodiment of the invention.

In den Fig. ist mit 1 die Getriebewelle des Fahrzeugs bezeichnet. Die Getriebewelle endigt in einem Kegelradausgleichsgetriebe, das in einem Getriebekasten liegt, von dem ein Wandteil bei 3 angedeutet ist. Auf der Getriebewelle 1 ist ein Ring 1a festgekeilt, der an seiner Außenfläche genutet ist. Eine Scheibe 2 ist schwimmend an dem Hutenring 1a gehaltert. Die Scheibe 2 ist mit den Nuten des Nutenrings 1a im Eingriff und auf diese V/eise mit der Getriebewelle 1 zur gemeinsamen Drehung gekuppelt. Es können mehr als eine Scheibe 2 mit der Welle 1 gekuppelt sein.In the figures, 1 designates the transmission shaft of the vehicle. The gear shaft ends in a bevel gear, which is located in a gear box, of which a wall part at 3 is indicated. A ring 1a, which is grooved on its outer surface, is keyed onto the transmission shaft 1. A disk 2 is held in a floating manner on the hat ring 1a. The disc 2 is in engagement with the grooves of the grooved ring 1a and in this way is coupled to the transmission shaft 1 for common rotation. More than one disk 2 can be coupled to the shaft 1.

An einer Wand 3 ist seitlich ein Zangenkörper 4 gehaltert, der mit einer Montageplatte versehen ist, die an der Wand 3 mit Schrauben befestigbar ist. Der Zangenkörper hält eine Querwelle 8, die auf einem Ende einen Hocken 7 trägt, der auf ein bewegliches Element 6 der Zange einwirkt, um dieses bei Dre-On the side of a wall 3, a pliers body 4 is supported, which is provided with a mounting plate that is attached to the wall 3 with Screws can be fastened. The pliers body holds a transverse shaft 8, which carries a crouch 7 on one end, which on a movable element 6 of the pliers acts in order to

609832/0598609832/0598

hung der Welle 8 gegen ein festes Gegenelement 5 zu drücken und so die Scheibe 2 zwischen Bremsbelägen der Zangenelemente einzuklemmen. Auf dem anderen Ende der Welle 8 ist ein Arm 9 festgekeilt, der über eine Stange 11 mit einem Handbedienungshebel 10 verbunden ist, der in bekannter Weise mit einem lösbaren Klinkengesperre versehen ist.Hung of the shaft 8 to press against a fixed counter element 5 and so the disc 2 between the brake pads of the caliper elements to pinch. On the other end of the shaft 8, an arm 9 is wedged, which is connected via a rod 11 to a manual control lever 10, which in a known manner with a detachable Ratchet lock is provided.

Beim Betätigen des Bremshebels 10 wird die Querwelle 8 gedreht, wobei der Nocken 7 das bewegliche Element 6 der Zange gegen das feststehende Element 5 preßt und damit das Fahrzeug bremst.When the brake lever 10 is actuated, the transverse shaft 8 is rotated, the cam 7 against the movable element 6 of the pliers the fixed element 5 presses and thus brakes the vehicle.

Die gezeigte Bremse hat eine äußerst einfache Konstruktion und macht es möglich, die Bremszange bequem und rasch auszubauen, um die Bremsbeläge zu wechseln. Zudem ist es möglich, sehr dünne Bremselemente oder Bremsbeläge zu verwenden, wodurch sich die Kosten für die Bremse und für die Instandhaltung derselben verringern.The brake shown has an extremely simple construction and makes it possible to remove the brake calliper easily and quickly, to change the brake pads. It is also possible to use very thin brake elements or brake pads, which means the costs for the brake and for the maintenance thereof are reduced.

Die kleineren Abmessungen der Bremsbeläge erlauben die Konstruktion einer Mehrscheibenbremse, wie sie in Mg.4 gezeigt ist. In dieser Konstruktion sind zwei parallele Scheiben 2, mit dem Nutenring 1a gekuppelt, der auf der Welle 1 verkeilt ist? die Scheiben 2, 2' liegen zwischen Elementen 5 und 6 der Zange.The smaller dimensions of the brake pads allow the construction a multi-disc brake as shown in Mg.4. In this construction there are two parallel discs 2, coupled to the grooved ring 1a, which is wedged on the shaft 1 is? the discs 2, 2 'lie between elements 5 and 6 of the Tongs.

Im Rahmen der Erfindung können die praktischen Ausführungen und die Konstruktionsdetails gegenüber den beschriebenen und gezeigten Beispielen variieren.Within the scope of the invention, the practical designs and the construction details compared to those described and examples shown vary.
