Description
Die Erfindung bezieht sich auf ein Handrad zum Betätigen von Bremsen, Entladeklappen u. dgl. bei Schienenfahrzeugen, das einen. kreisförmigen, mit der Nabe über beidseitig angeschweißte Hohlspeichen verbundenen Rohrkranz mit mindestens einer Unterbrechung aufweist, in die ein Anschlußteil für einen in die Ebene des Handrades, schwenkbaren Handgriff eingeschweißt ist.The invention relates to a handwheel for operating brakes, Unloading flaps and the like in rail vehicles, one. circular, with the The hub is connected by tubular rings welded on both sides with at least has an interruption in which a connector for a in the plane of the Handwheel, swiveling handle is welded.
Bei einem bekannten, aus Rohrteilen bestehenden Handrad besteht das, die beiden Enden des Rohrkranzes miteinander verbindende Anschlußteil aus einem U-förmig gebogenen Bügel, zwischen dessen zur Radnabe gerichteten Schenkeln die Schwenkachse des in die Ebene des Handrades. schwenkbaren Handgriffes angeordnet ist. Die Rohrkranzenden sind hierbei an die Außenflächen der Bügelschenkel angeschweißt.In a known handwheel consisting of tubular parts, the the two ends of the tube ring connecting to each other from a connector U-shaped bent bracket, between its legs facing the wheel hub the Swivel axis of the in the plane of the handwheel. arranged pivotable handle is. The tube rim ends are welded to the outer surfaces of the bracket legs.
Außerdem ist auch bekannt, zwischen die Schenkel des Bügels einen zweiten, mit seinen Außenflächen gegen die Schenkelinnenflächen anliegenden Bügel einzusetzen, zwischen dessen Schenkeln die Schwenkachse des Handhebels angeordnet ist. Beide Bügel sind durch Schweißung miteinander verbunden.It is also known to have one between the legs of the bracket second bracket resting with its outer surfaces against the inner surfaces of the legs use, arranged between the legs of the pivot axis of the hand lever is. Both brackets are connected to one another by welding.
Diese Ausführungsformen sind infolge ihrer vielen Einzelteile aufwendig in Herstellung und Zusammenbau. Wegen ihrer über den Außenumfang des Rohrkranzes vorstehenden Stegecken können sie außerdem Unfälle verursachen. Zur Unfallverhütung ist man bestrebt - der einklappbare Handgriff beweist das. -, die äußere runde Randform des- Rohrkranzes nicht durch vorstehende Teile zu stören.These embodiments are expensive due to their many individual parts in manufacture and assembly. Because of their over the outer circumference of the tube ring They can also cause accidents. To prevent accidents if you strive - the foldable handle proves it. -, the outer round edge shape of the pipe ring not to be disturbed by protruding parts.
Durch die Erfindung sollen eine- Vereinfachung des Handrades und eine Verringerung der Unfallgefahr erreicht werden. Dies geschieht erfin.dungs: gemäß dadurch, daß die Schwenkachse des Handgriffes, dessen Lagermuffe hohlzylindrische, die äußere runde Randform des Rohrkranzes weitgehend wahrende Form aufweist, als An.schlußteil dient und mit dem Rohrkranz verschweißt ist. Die Lagermuffe des Handgriffes ist hiernach nicht mehr auf in einem besonderen Haltestück befestigten Lagerzapfen gelagert, sondern unmittelbar auf dem die Rohrkranzenden miteinander verbindenden Anschlußteil, so daß nach Wegfall des Haltestückes die hohlzylindrische Lagermuffe die Randform des Rohrkranzes weitgehend wahrt.The invention aims to simplify the handwheel and a Reduction of the risk of accidents can be achieved. This is done according to the invention in that the pivot axis of the handle, the bearing sleeve of which is hollow-cylindrical, the outer round edge shape of the tube ring has largely preserving shape than Connecting part is used and is welded to the tubular ring. The bearing sleeve of the handle is no longer on bearing journals fastened in a special retaining piece stored, but directly on the one connecting the pipe rim ends with one another Connection part, so that after omission of the holding piece, the hollow cylindrical bearing sleeve largely preserves the edge shape of the tube ring.
In der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargestellt.In the drawing, an embodiment of the invention is for example shown.
Abb. i zeigt die Draufsicht auf das Handrad; Abb. 2 zeigt einen Schnitt nach der Linie a-b der Abb. i. -Die Enden des kreisförmig gebogenen Rohrkranzes i sind mit dem im Querschnitt runden Anschlußteil 2 durch Schweißung verbunden. Auf dem Anschlußteil2 ist die hohlzylindrische Lagermuffe 6 des Handgriffes gelagert. Drei Hohlspeichen q. mit ovalem Querschnitt verbinden den Rohrkranz i mit der Nabe 5.Fig. I shows the top view of the handwheel; Fig. 2 shows a section according to the line a-b of Fig. i. -The ends of the circular bent pipe ring i are connected to the connecting part 2, which is round in cross section, by welding. The hollow cylindrical bearing sleeve 6 of the handle is mounted on the connecting part 2. Three hollow spokes q. with an oval cross-section connect the tubular ring i to the hub 5.
