Die Übertragung der Bremsbewegung von einem Punkte des Wagengestells auf die Bremsklötze ist bei solchen Fahrzeugen, deren Radachsen oder Radachsgruppen zugleich um mehrere geometrische Achsen, insbesondere um eine lotrechte und um eine wagerechte Achse pendeln sollen, besonders schwierig, weil hierbei das Bremsgestänge außer seiner Hauptbewegung zur Beeinflussung der Bremsen zum Teil die ίο Pendelungen der Radachsen mitmachen .muß, falls das Gestänge ohne Verzerrungen und Klemmungen arbeiten soll.The transfer of the braking movement from one point on the carriage frame to the brake pads is in such vehicles, whose wheel axles or wheel axle groups at the same time by several oscillate geometric axes, in particular around a vertical and a horizontal axis should, particularly difficult, because here the brake linkage apart from its main movement To influence the brakes, the ίο oscillations of the wheel axles have to participate. if the linkage should work without distortion and jamming.

'Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Bewegung des Bremsgestänges zwischen je zwei gegeneinander schwingenden Fahrzeugteilen in der geometrischen Achse der Schwingzapfen des pendelnden Fahrzeugteils übertragen wird. Dabei wird die Bremsspindel, die von einem Punkte des Wagengestells bedient wird, in an sich bekannter Weise durch den Drehgestellzapfen zwischen der Wagenplattform und den Radsätzen hindurchgeführt. Bei mehreren Rädern eines und desselben Pendelsystems wird gemäß der Eras findung der das gleichmäßige Anziehen der Bremse vermittelnde Ausgleichhebel schwingbar um die Pendelachse in einer zur Radachse parallelen Ebene angeordnet.'This object is achieved according to the invention in that the movement of the brake linkage between two mutually oscillating vehicle parts in the geometric axis of the pivot pin of the oscillating vehicle part is transmitted. In doing so, the brake spindle is driven by one point on the carriage frame is operated, passed in a known manner through the bogie pin between the car platform and the wheelsets. If there are several wheels of one and the same pendulum system, according to the Eras invention, the uniform tightening of the Brake-mediating compensation lever swingable around the pendulum axis in one direction to the wheel axis arranged parallel plane.

Ein Ausführungsbeispiel, das auf der Zeichnung veranschaulicht ist, soll zur Erläuterung des Erfindungsgedankens dienen.An exemplary embodiment which is illustrated in the drawing is intended for explanation serve the inventive idea.

Fig. i, 2 und 3 der Zeichnung stellen, teilweise im Schnitt, einen Plattformwagen mit acht schwinghar und drehbar gelagerten Rädern und einer Bremsausrüstung gemäß der Erfindung von der Seite, von vorn und von oben gesehen dar.Fig. I, 2 and 3 of the drawing represent, partially in section, a platform wagon with eight swinging and rotating wheels and braking equipment according to the invention viewed from the side, from the front and from above represent.

Fig. 4 zeigt in vergrößertem Maßstabe eine Einzelheit des Bremsgestänges im Auf- und Grundriß. ·Fig. 4 shows on an enlarged scale a detail of the brake linkage in the up and Layout. ·

In dem dargestellten Beispiel sind sämtliche Räder in zwei Hauptgruppen angeordnet, deren Achsen bei einer Fahrt auf gerader und glatter Bahn in zwei zueinander parallelen Geraden a und b liegen. Mit dem Fahrzeugrahmen oder der Plattform c, die in beliebiger Weise zur Aufnahme der Last dient, ist jede ,der Hauptradgruppen durch ein Drehgestell, z. B. d, in der Weise verbunden, daß sich die betreffende Radgruppe um einen lotrechten Zapfen, z. B. e, drehen kann. Jede Hauptradgruppe ist gemäß dem dargestellten Beispiel weiterhin in eine beliebige Anzahl Radgruppen derart unterteilt, daß die Radachse f, die beispielsweise zwei Räder g trägt, in einem Gestell d₁ gelagert ist, das pendelnd an zwei im Drehgestell ruhenden Zapfen h aufgehängt ist. Die wagerecht liegende Achse dieser Zapfen steht rechtwinklig zur Radachse f. In the example shown, all wheels are arranged in two main groups, the axes of which lie in two parallel straight lines a and b when driving on a straight and smooth path. With the vehicle frame or the platform c, which is used in any way to accommodate the load, each of the main wheel groups by a bogie, z. B. d, connected in such a way that the wheel group in question is around a vertical pin, e.g. B. e, can rotate. According to the example shown, each main wheel group is further subdivided into any number of wheel groups such that the wheel axle f, which carries, for example, two wheels g, is _{mounted in a frame d 1,} which is suspended pendulously on two pegs h resting in the bogie. The horizontal axis of this pin is at right angles to the wheel axis f.

Das Bremsgestänge für einen derartigen Wagen wird nun im Sinne der Erfindung gemäß dem dargestellten Ausführungsbeispiel in der folgenden Weise ausgebildet:The brake linkage for such a car is now in accordance with the invention according to illustrated embodiment in the following way:

Die Antriebsspindel i für die Bremse, die von einem Punkte des Fahrzeuggestells c angezogen oder gelöst werden kann, ist ähnlich einer bekannten Ausführung durch den Drehzapfen β des Drehgestells d hindurchgeführt undThe drive spindle i for the brake, which can be attracted or released from a point on the vehicle frame c , is passed through the pivot β of the bogie d and similar to a known embodiment

Claims

stored in it at the same time. As a result, a rotation of the bogie d with respect to the platform c is equivalent to a rotation of the frame d with respect to the spindle i. To transmit the drive of the brake spindle i, an angle lever w mounted in the bogie d is used, the horizontal leg of which engages the brake spindle nut, while the vertical leg is connected to a rod χ leading to the rear in the center axis of the bogie d. A horizontally lying compensating lever p acts on this rod, the ends of which are each connected to an arm q of a horizontally running shaft k ″ mounted on the bogie rf. This shaft k is used to transmit the movement of the brake linkage according to the invention by means of an arm s in the geometric axis of the oscillating spigots h, which enable the oscillation between the bogie d and the wheel axle frame dx. At this point, the arm s (cf. also FIG. 4) engages in the center pin H1 of a compensating lever m, the ends of which are connected to the tie rods I, which set the arms 0 of the brake k arranged in each wheel g in motion. Since the compensating levers m, due to their rigid connection with the brake shoes k, take part in the oscillating movement of each individual wheel group with respect to the main bogie (cf. 4) that it allows this swinging of the lever m with respect to the arm s in a vertical plane without hindrance. This design of the brake linkage in such a way that the movement of the brake linkage between two mutually oscillating vehicle parts - for example between c and d and between d and dx - in the geometric axis of the pivot pin, i.e. in the axis of e on the one hand or On the other hand, the axis of the pin h is transmitted, any jamming or distortion of the linkage when applying or releasing the brakes is avoided, although the wheel axles can be inclined or rotated relative to one another as desired. The invention can be applied not only to the individual case shown in the drawing, but also to all possible groupings of rotatable wheel frames and oscillating wheel groups. In particular, the brake arrangement can also be installed in motor vehicles and their trailers that are intended to be used to move larger loads on uneven roads. Pa τ ε nt claims:

1. Brake for road vehicles, their wheelsets or groups of wheelsets not only to a vertical, but also to any other, z. B. can swing the horizontal axis; characterized in that the brakes of all wheels are attracted and released from one point of the vehicle frame in such a way that - using the known passage of spindles through the bogie pin (e) - the movement of the brake linkage between two mutually swingable vehicle parts is transmitted in the geometric axis of the pivot pin of the oscillating vehicle part.

2. Brake according to claim 1, characterized in that when there are several wheels (g) of one and the same pendulum system, the equalizing lever (m) which mediates the uniform application of the brakes can oscillate about the pendulum axis (h) in a plane parallel to the wheel axis.
