Es ist bei Rangierbremsen bekannt, durch ein in eine Verzahnung greifendes Gesperre die Bremse in der Bremsstellung zu erhalten und, um die Bremse in die Lösestellung zu bringen und in dieser zu erhalten, das Gesperre auszurücken und den Handhebel durch eine am Fahrzeug angebrachte Rast zu unterstützen. Bei Rangierbremsen dieser Art sind die die Aufwärtsbewegung der HandhebelIt is known for maneuvering brakes through a locking mechanism that engages in a toothing to get the brake in the braking position and to put the brake in the release position bring and get in this, disengage the lock and pull the lever through to support a rest attached to the vehicle. When maneuvering brakes of this type are which is the upward movement of the hand lever

ίο auf das Gesperre übertragenden und das Gesperre auslösenden Organe derart angeordnet, daß der Übergang in die Bremsstellung nicht kraftschlüssig erfolgt. Infolgedessen wird durch Schmutz, Rost u. dgl. die Bremse leicht beeinflußt und wirkt nicht immer ordnungsmäßig. ίο to the locking mechanism and the locking mechanism triggering organs arranged so that the transition to the braking position is not takes place frictionally. As a result, the brake is damaged by dirt, rust and the like easily influenced and does not always work properly.

Gemäß der Erfindung wird die Ausrückklinke an dem Handhebel angeordnet, welcher neben dem mit Sperrzahn und Sperrnase ver-According to the invention, the release pawl is arranged on the hand lever, which in addition to the one with ratchet and ratchet

sehenen Bremshebel liegt und beim Übergang in die Brems- und in die Lösestellung kraftschlüssig geführt wird.The brake lever seen lies and frictionally engages when transitioning into the braking and releasing positions to be led.

Fig. 5 veranschaulicht die Sperr- und die Auslösevorrichtung in der zum Anziehen der Bremse bereiten Stellung und Fig. 6 in der Bremsstellung. Fig. 7 stellt in Seitenansicht eine andere Ausführungsform dar.Top view. Fig. 3 and 4 show a side view respectively. the top view of the lock and Release device in the release position. Fig. 5 illustrates the locking and triggering devices in the position ready to apply the brake and FIG. 6 in the braking position. Fig. 7 shows a side view of another embodiment.

Auf der Handhebelwelle α oder auf einem Zapfen des Halters d ist der Bremshebel g The brake lever g is on the hand lever shaft α or on a pin of the holder d

dicht an der Innenseite des Handhebels e drehbar gelagert und durch den Lenker 4 mit dem Hebel 5 verbunden, der auf das Bremsgestänge wirkt.rotatably mounted close to the inside of the hand lever e and connected by the handlebar 4 to the lever 5, which acts on the brake linkage.

Am Bremshebel g sitzt der unter den Handhebel e greifende Anschlag h, durch welchen der Bremshebel g beim Herunterdrücken des Handhebels mitgenommen wird. Beide Hebel g und e bewegen sich zwischen den am Untergestell befestigten Führungsbogen k und m (Fig. 2). Die Führungsbogen sitzen konzentrisch zur Handhebelwelle a, und die äußere Bogenfläche des inneren Führungsbogens k ist mit Sperryerzahnung 0 und die innere Bogenfläche des Führungsbogens m mit der Rast ρ versehen. Der knieförmige, bei t abgestufte Sperrarm s ist am Bremshebel g an dessen Innenseite drehbar befestigt. Der Sperrzahn q desselben kann mit der Verzahnung ο am Führungsbogen k, die Sperrnase r mit der Rast ρ des Führungsbogens m und der Fortsatz u hinten am aufrechten Schenkel des Knies des Sperrarmes s mit der Ausrückklinke ν zusammenwirken. The brake lever g of the cross under the hand lever e stop sitting h, is entrained by which the brake lever g while pressing down the hand lever. Both levers g and e move between the guide arches k and m which are attached to the underframe (FIG. 2). The guide arches sit concentrically to the hand lever shaft a, and the outer arch surface of the inner guide arch k is provided with Sperryer teeth 0 and the inner arch surface of the guide arch m with the detent ρ . The knee- shaped locking arm s , stepped at t , is rotatably attached to the inside of the brake lever g. The locking tooth q of the same can interact with the toothing ο on the guide arch k, the locking nose r with the detent ρ of the guide arch m and the extension u at the back of the upright leg of the knee of the locking arm s with the release pawl ν .

Die winkelförmige Ausrückklinke ν ist an dem Arm w des Handhebels e bei 3 angelenkt. Der Arm χ der Klinke ν kann mit der oberen Fläche und der Arm y mit dem Fortsatz u des Sperrarmes s zusammenwirken.The angled release pawl ν is hinged to the arm w of the hand lever e at 3. The arm χ of the pawl ν can interact with the upper surface and the arm y with the extension u of the locking arm s .

Der Bremshebel g endigt _sin einer Abschrägung 1, auf der zeitweilig die Nasey der Ausrückklinke ν geführt wird (Fig. 3 und 6).The brake lever terminates in a bevel g _s 1 which was temporarily the nose of the y Ausrückklinke is guided ν (Fig. 3 and 6).

In der Lösestellung der Bremse befindet sich der Handhebel e außer Berührung mit dem Anschlag h des Bremshebels g (Fig. 1 und 3). Die Nase r des Sperrarmes s liegt in der Rast p, der Sperrzahn q ist aus derIn the brake release position, the hand lever e is out of contact with the stop h of the brake lever g (FIGS. 1 and 3). The nose r of the locking arm s is in the detent p, the ratchet q is out of the

Claims

Toothing ο disengaged and the extension ti out of engagement with the nose y of the release pawl v. When the raised hand lever e is released, the release pawl v, whose arm χ is based on the forward leg of the locking arm s, rotated under the effect of its weight, until its nose y hit the inclined surface ι on the brake lever g. ίο To bring about the braking position, the hand lever e is raised until the nose y of the release pawl ν meets the extension u of the locking arm s and by forward rotation of the latter brings the nose r out of the detent ρ (Fig. 5). If you then let the hand lever e fall, the brake is in the braking position, and by pushing the hand lever e further down, the same acts on the stop h of the brake lever g. The brake is tightened and the locking tooth q of the locking arm s falling into the toothing locks the hand lever e in the braking position when it is released. The brake is released again by turning the hand lever e upwards. The pawl ν is held in the appropriate position by the inclined surface ι at the end of the brake lever g, while the hand lever strikes under the nose r of the locking arm s and rotates the same back so that its locking tooth q loses engagement with the toothing 0. The brake lever g is raised until the nose r falls back into the detent ρ of the guide m (Fig. 1 and 3). In the embodiment according to FIG. 7, the hook y of the release pawl ν is guided under the rear end of the brake lever g in the release position through the upper arm χ of the pawl v, which rests against the upper edge of the locking arm s. If the hand lever e is lifted, the brake lever g is lifted at the same time until the part of the locking arm protruding over the ratchet tooth q meets the inclined surface 12 of the part 13 protruding on the inner guide arc k, causing the locking arm to rotate forward, the nose r moved out of the detent ρ and a further upward rotation of the levers g and e is prevented, which then fall freely and apply the brake, whereby the ratchet q engages the ratchet 0 and keeps the brake pads tightened. When the ratchet tooth q engages in the toothing 0, the lower arm 14 of the latter meets the lateral projection 11 on the lower arm of the pawl v; this gets out of the area of the brake lever g, and when the hand lever e is then lifted, it can push freely under the nose r and disengage the ratchet q from the ratchet ο. Both hand levers e and f can be equipped with the locking and release device. Patent-A ν proverbs:

1. A shunting brake with locking device for the hand lever in the braking and release position and automatic locking release pawl, characterized in that the locking device release and hand lever locking device consists of a pawl (v) which can be rotated on the hand lever and forms an angle lever, against the arms (xy) the locking arm fs) resp. the beveled end of the brake lever (g) act in such a way that the pawl (v) either into the hand lever
