Description

Bremsvorrichtung, insbesondere für elektrisch betriebene Schienenfahrzeuge Das Hauptpatent 452 517 betrifft eine Bremsvorrichtung für elektrisch betriebene Schienenfahrzeuge, die im wesentlichen aus einer neben dem Motorlagerschild angeordneten Innenba ckenbremse besteht, deren Bremsbacken unmittelbar am Lagerschild gelenkig .befestigt sind. Wie im ersten Zusatzpatent 458 332 ausgeführt wurde, kann zwecks weiterer Platzersparnis die Bremstrommel innerhalb des Motorgehäuses gelagert und dort mit anderen umlaufenden Maschinenteilen, beispielsweise dem für die Kühlung sorgenden Lüfter, zusamnuengebaut sein. Die Bremsbacken sind in diesem Falle an der Lagerschildinnenwand gelenkig befestigt.Braking device, in particular for electrically operated rail vehicles The main patent 452 517 relates to a braking device for electrically operated Rail vehicles, which essentially consist of an arranged next to the engine bearing plate Inner jaw brake exists, the brake shoes of which are articulated directly on the end shield .are attached. As was stated in the first additional patent 458 332, for the purpose of further space saving, the brake drum is stored within the motor housing and there with other rotating machine parts, for example the one for cooling caring fan, be assembled. The brake shoes are on in this case articulated to the inner wall of the end shield.

Eine weitere Verbesserung und Raumersparnis läßt sich erfindungsgemäß dadurch erreichen, daß die Reibungsfläche durch eine senkrecht und quer zur Motorachse liegende Fläche gebildet wird und die Anpressung der Bremsbacken, die aus Gründen der Einfachheit auch zu einer mit Belag versehenen Ringscheibe vereinigt sein können, in der Achsenrichtung des Motors erfolgt. Die umlaufende Bremsscheibe kann dabei durch die Rückwand des Maschinenlüfters gebildet werden. Durch diese Ausführung der Getriebebremse ist ein Weg zur Ausnutzung der Vorteile der Ankerbremse auch für Schmalspurbahnmotoren gegeben.A further improvement and space saving can be achieved according to the invention achieve that the friction surface by a perpendicular and transverse to the motor axis lying surface is formed and the pressure of the brake shoes for reasons the simplicity can also be combined to form an annular disc provided with a lining, takes place in the axial direction of the motor. The rotating brake disc can be formed by the rear wall of the machine fan. Through this execution The transmission brake is a way of taking advantage of the armature brake too given for narrow-gauge railway engines.

In der Zeichnung ist ein Ausführungsbeispiel abgebildet. Die Motorwelle a trägt den Maschinenlüfter c, dessen Rückwand b als Bremsscheibe dient. Eine Scheibe d, die mit einem Bremsbelag e versehen ist, kann gegen die Scheibe b bewegt und an diese abgedrückt werden. Dieses Andrücken in der Achsenrichturig des Motors erfolgt mittels der Bolzen g entgegen dem Druck von Federn f. Eine verdrehbare Scheibe h isst mittels des Gewindes i. auf dem Lagerschild h des Motors gelagert. Durch den mit der Scheibe h verbundenen Hebel na wird die Scheibe gedreht und hierbei gleichzeitig in der Achsenrichtung des Motors verschoben; diese Bewegung wird über Kugeln n auf die Bolzen g und den beweglichen Teil d der Bremse übertragen.An exemplary embodiment is shown in the drawing. The motor shaft a carries the machine fan c, the rear wall b of which serves as a brake disc. A disc d, which is provided with a brake lining e, can be moved against the disc b and pressed against it. This pressing in the axial direction of the motor takes place by means of the bolts g against the pressure of springs f. A rotatable disk is attached by means of the thread i. stored on the end shield h of the motor. By means of the lever na connected to the disk h, the disk is rotated and at the same time displaced in the axial direction of the motor; this movement is transmitted via balls n to the bolts g and the moving part d of the brake.

Wie ersichtlich, nimmt die Bremseinrichtung, in axialer Richtung gemessen, nur sehr wenig Raum ein. Der Lagerdeckel c wird durch die Bremseinrichtung gerade nur um die Stärke der Scheibe h überragt,As can be seen, take t the braking device, as measured in the axial direction, only very little space. The braking device only projects beyond the bearing cap c by the thickness of the disk h,
