Die Erfindung betrifft eine Bremse für Fahrzeuge aller Art, bei der durch Zurückschieben einer Stange beim Zurückhalten der Zugtiere die Bremsklötze angezogen werden. Bremsen dieser Art sind bereits bekannt und erfolgt das Bremsen des Fahrzeuges dadurch, daß die Verschiebung der meistens an der Deichsel befestigten Stange durch geeignete Hebel auf die Bremsklötze übertragen wird, wobei dieThe invention relates to a brake for vehicles of all types in which by pushing back a rod when holding back the draft animals, the brake pads are tightened. Brakes of this type are already known and the vehicle is braked in that the shifting of the rod, which is usually attached to the drawbar, by means of suitable levers the brake pads is transferred, the

ίο Bremseinrichtung so ausgebildet sein kann, daß es möglich ist, die Bremse auch von Hand anzuziehen. Von diesen Vorrichtungen unterscheidet sich der Gegenstand der Erfindung durch seine Wirkungsweise und besondere Bauausführung, die darin besteht, daß die verschiebbare Stange gelenkig und nachstellbar an das freie Ende eines durch Doppelhebel mit den Bremsklötzen in Verbindung sehenden Hebels angeschlossen ist, wobei am Wagengestell drehbar befestigte Handhebel mit den ersteren Hebeln derart in Eingriff sind, daß die Bremse von Hand angezogen werden kann, welche Wirkung jedoch bei Ausübung eines Zuges an der Stange aufgehoben wird, und daß die Bremse in der Ruhelage der Handhebel festgestellt ist.ίο The braking device can be designed in such a way that that it is possible to apply the brake by hand. From these devices the subject of the invention differs in its mode of action and special Construction, which consists in that the sliding rod is articulated and adjustable is connected to the free end of a lever that is connected to the brake pads by double levers, with am Car frame rotatably attached hand levers with the former levers so engaged are that the brake can be applied by hand, which effect is canceled when a pull is exercised on the rod is, and that the brake is locked in the rest position of the hand lever.

Die Lafette A ist auf der Achse B in geeigneter Weise befestigt, auf deren freien Enden die Räder C drehbar sitzen. Das Rohr D ruht mit seinen seitlichen Zapfen E in entsprechenden Lagern der Lafettenwände und unterhalb desselben ist innerhalb der Lafette die in eine Verbindungsöse endigende · Zugstange F angeordnet, welche auf die Bremsklötze G verstellend einwirkt.The mount A is fastened in a suitable manner on the axis B , on the free ends of which the wheels C are rotatably seated. The tube D rests with its lateral pins E in corresponding bearings of the carriage walls and below the same the pull rod F , which ends in a connecting eye and acts on the brake pads G, is arranged inside the carriage.

Die beiden Bremsklötze G wirken entweder auf den Umfang oder die Naben der beiden Roder C, oder aber auf den inneren oder äußeren Umfang einer besonderen, an die. Innenseite eines jeden Rades angeschlossenen Bremsscheibe oder Trommel (Fig. 6) ein. Die beiden Bremsbacken, die aus Holzklötzen o. dgl. hergestellt sein können, sind an den Enden einer Querstange H angebracht, die von an der Lafette befestigten Winkelstücken I getragen wird, so daß die Querstange in der Wegrichtung verschoben werden kann. Die Querstange H ist durch ein oder mehrere verstellbare Stangen /, beispielsweise je eine auf jeder Seite der Lafette, mit den unteren Enden zweier doppelarmiger Hebel K, K¹ verbunden, die in entsprechendem Ab-The two brake pads G either act on the circumference or the hubs of the two Roder C, or on the inner or outer circumference of a special one, on the. Inside of each wheel connected to the brake disc or drum (Fig. 6). The two brake shoes, which can be made of wooden blocks or the like, are attached to the ends of a crossbar H , which is supported by angle pieces I attached to the mount, so that the crossbar can be moved in the direction of travel. The cross rod H is connected by one or more adjustable rods /, for example one on each side of the mount, to the lower ends of two double-armed levers K, K ¹ , which are

stood from each other on a transverse shaft L are attached. The upper arm of each double lever is longer than the lower one, and the transverse shaft L is located in suitable bearings on the carriage or in the carriage frame. Furthermore, a lever M, N is rotatably arranged on a short transverse rod or spindle O on each side of the mount A , in such a way that they can be moved independently of one another; if necessary, they can each sit on a special pin on the outside of the mount. The lever M has a lower, short, thumb-like, inner arm which initially works together with one of the double levers K and then secures it in its position. The lower thumb-like lever arm of the lever M is made shorter than its upper arm, which can be bent to the knee or curved upwards so that it can act as a hand lever m . The double lever M can act on the levers K, K ¹ to which the adjustable connecting rods J and the brake or pull rod F are connected in order to enable the brake pads G to be tightened by hand. The longer end k of the lever K is provided on one side with a projection A: ¹ , which forms a locking or holding thumb that enters the correspondingly shaped recess on the inside of the lever M as soon as the brake pads G hit the wheels C place. The other lever N is only one-armed and equipped with a curved thumb η which, as can be seen from FIG. 5, protrudes on one side of the lever and engages over the upper end of the lever arm / c ^{2 of} the lever K ¹ . The purpose of the latter is to enable a special securing of the brake pads, both when they are in and out of the braking position. In certain cases it might even be advisable to omit the lever K ¹ entirely and to use the lever K alone.

In addition to these manual levers K, K ¹ , several levers are arranged on or on the transverse shaft L or, as shown, only a single one, at the free end of which the pull rod F of the vehicle is adjustable or connected in some other way; for example, as in the present case, the connection can be made by means of the screw bolt Q. and the locking nuts R. The forward movement of the tie rod causes one or more stops S of the same to lie against one or more plates T or guide strips which are attached to the underside of the carriage or the carriage frame (see FIGS. 1 and 2). The lever P, which sits with the double-armed lever K, K ¹ on the common shaft L , allows the brake pads G to be easily and automatically tightened as soon as the vehicle starts to run faster than the horse or some other pulling force on its own when driving downhill. If the vehicle then runs on a level track or if it has to climb an incline, the brake pads are immediately put out of action when the pull on the pull rod F occurs.

The levers M and N, the upper arms of which are designed as hand levers, can also be moved from the front of the carriage or the carriage.

In certain cases it should also be advantageous to let the brake pads G act on the wheel hubs or also on the inner or outer rim surface of brake disks U (FIG. 6) which are attached to the inside of each wheel. In this embodiment, the connecting rods J can be made much shorter and the individual parts can be brought closer together.

The device described can be attached to any vehicle without replacing or changing the wheel axles or the fastening of the wheels. The pressing action of the brake shoes can be changed as required by adjusting the connecting rod, the pull rod F and the levers K, K ¹ .
