Definitions

the invention relates to a support and centering device for automatic couplings of rail vehicles, with a flexible, designed as a rope, belt, chain or the like tension member, the ends of which are held laterally and above the coupling shaft of the coupling on the vehicle frame and rests on the central region of the coupling shaft , wherein the tension member is attached to at least one of its ends via a spring member on the vehicle frame and is guided directly in front of this end via a directionally deflecting, rotatably mounted roller on the vehicle frame.
Such a support and centering device is known from DE-Bl O38 59l.
the rope-like tension member is clamped immovably on the coupling shaft, it is even designed to be separated in the region of the coupling shaft between two clamping points.
the other ends of the rope are guided on rollers rotatable about transverse axes on the vehicle frame and suspended on simple tension springs, which run horizontally backwards and are held with their rear ends on the vehicle frame. From this arrangement it follows that with vertical deflections of the coupling, the two springs are equally loaded, with side deflections of the coupling against one spring and the other is relaxed; in the latter case there is an unfavorable use of the spring.
Another shortcoming of this known support and centering device can be seen that the rest position of the clutch is determined solely by the state of equilibrium between the clutch weight and the spring preload, and can therefore already be changed by slight spring fatigue.
DE-C-l OO5 548 shows one of the similar support and centering device described above, but the traction member, which is, however, continuously formed is also rigidly clamped to the coupling shaft and is articulated with its ends to levers which are rotatable against spring force and are mounted on the vehicle frame.
the coupling shaft has a roller which is rotatable about an axis of rotation which is at least approximately parallel to its longitudinal direction and which rests on the tension member.
a coupling shaft l which runs perpendicular to the plane of the drawing and one end of which is pivotably articulated on the vehicle frame and the other end of which carries the coupling head, also not shown, is provided on its underside with a rotatable roller 2, the axis of which is parallel to Longitudinal direction of the coupling shaft runs.
the roll 2 stands on a rope-like tension member 3 that can be unrolled and runs obliquely upwards on both sides of the coupling shaft 1 and toward the vehicle side.
One end 4 of the tension member 3 is fastened to the vehicle frame 5 so as to be pivotable about an axis of rotation parallel to the longitudinal direction of the vehicle.
the tension member 3 runs shortly before its end 6 via a roller 7 which deflects the tension member 3 in such a way that its end section runs obliquely downwards and inclines toward the center of the vehicle.
the axis of the roller 7 runs approximately parallel to the longitudinal direction of the vehicle.
the end 6 of the tension member 3 is provided with a stop part 8 which bears on the tension member side against a cage part 9 of a two-part spring cage 10.
the cage part 9 is coupled via a pull stop ll to a further cage part l2, which is supported on the vehicle frame 5 opposite the stop part 8.
the spring cage lO there is a first spring l3 which is penetrated by the tension member 3 and which spreads the two cage parts 9 and l2 apart.
a second spring 14 is clamped between the stop part 8 and the vehicle frame 5 and is arranged to surround the spring cage 10.
the two springs l3 and l4 are dimensioned such that in the illustrated rest state of the coupling and thus of the coupling shaft 1, the pull stop 11 is closed without a substantial excess of force, that is to say with only a small closing force.
the clutch shaft 1 always seeks to assume the rest position shown, slight changes in the preload forces of the springs l3 and l4, for example spring fatigue, do not affect this rest position. It is essential that when the coupling shaft 1 is deflected laterally, both springs l3 and l4 are compressed in order to achieve a restoring effect, which results in good spring utilization.
the roller 2 in conjunction with the roller 7 ensures that the rope length required between the end 4 and the roller 7 can be adjusted almost frictionless and wear-free during the deflection processes.
rollers 2 and 7 can be adapted to the tension member used in each case, for example in the case of chain-like tension members can be designed as chain wheels.
the roller 2 does not have to be below, it can also be stored inside or above the coupling shaft 1.
the spring cage comprising the spring cage lO and the two springs l3 and l4 in the manner shown with the longitudinal direction inclined obliquely upwards and towards the vehicle side
the spring element similar to that from the aforementioned DE- Bl O38 59l known type to be arranged parallel to the vehicle longitudinal direction, the axis of rotation of the roller 7 is to be rotated accordingly.
one end of the tension member 3 can only be designed to be tensionable with the spring l3 by the spring cage lO, while the other end of the spring also here is to be loaded by a roller to be guided tension member only by the spring 14 to be arranged at this other tension member end, wherein the spring 14 can be arranged in the compression direction by a pressure stop.
the springs are dimensioned so that in the rest position of the coupling shaft l both springs are in their intercepted position without substantial excess force.
the support and centering device for automatic couplings of rail vehicles has a flexible tension member (3), the ends of which are held on the vehicle frame (5) laterally and above the coupling shaft (1). At least one end of the tension member (3) is guided over a roller (7) and connected to the vehicle frame by a spring member (l3, l4).
the coupling shaft (l) is supported against the tension member (3) by a roller (2) which can be rolled on the tension member (3).
the roller (2) of the coupling shaft (l) ensures that the tension in the tension member sections on both sides of the coupling shaft (l) is always the same, which means that optimum spring utilization and clutch reset can be achieved even when the coupling shaft (l) is deflected sideways.
