"Weighing device for rail vehicles that can be braked depending on the load"

The innovation relates to a weighing device for rail vehicles that can be braked depending on the load, whereby the The vehicle body is suspended or supported by a pendulum or hook on the vehicle suspension.

The task of the innovation is to provide a weighing device for Specify rail vehicles that can be braked depending on the load, in particular freight wagons that do not have to be changed to the car body and in a particularly simple way, revenge can be taken on the axle suspension afterwards. The Weighing device according to the invention be housed largely operationally safe and easily accessible.

After the innovation, the task will be in the W '. ise solved that a pendulum or a shake articulated with the one Arm of an angle lever mounted on the vehicle is connected, the other arm of which is held with an ara vehicle Weighing valve is in communication. A preferred embodiment according to the innovation consists in that the Weighing valve in a spring block with a cavity and guided through the walls of the spring block Line connections for the weighing valve is arranged and near the lower end of the spring bracket of the angle lever is stored, one of which with a shake or a pendulum on one side of the vehicle suspension in Connected arm engages through an opening in the wall of the spring bracket and the other with it arm associated with the weighing valve moves into the

Furthermore, the celebration trestle can advantageously be attached to the bottom of the vehicle body. be, with the attachment ό ^ί . zen by üfi'nurgen in the. Eoden des Fahrzeug "-.

The Wmkelhe.-ei is arranged vore ^ n.ftcrveise on the spring bracket in such a way that at the end of one arn.e .., ei: e her ^ Öminlic.ie ochake or a conventional pendulum in / erbindu:; ^ with -ainer conventional Fahrz3Ugfederung can be attached.

The innovation vird described by way of example, which is schematically illustrated in the accompanying drawings. Herein shows;

Fig. 1 is a section through an innovation according to the invention

Weighing device and FIG. 2 shows a conventional axle suspension on a

conventional spring bracket, which by a die

Viegeeinrichtung contained spring bracket

the innovation is replaceable.

In the figures, the same parts are provided with the same reference symbols.

A spring bracket 2 is screwed to a car body 8,

which has a PohlrauiL in which a known per se Wicgeventr.l is held, its compressed air connections through the wall of the celebration trestle are performed. A bearing pin 5 is held near the lower end of the spring bracket which an angle lever 6 is rotatably mounted. One arm of the lever engages through a slot-shaped opening 7 in the wall of the spring bracket 2 and is articulated at its free end to a conventional pendulum 7 on a kit Leaf spring 3 connected. The other arm of the bell crank 6 extends into the cavity of the spring bracket 2 and presses via a stop on the known weighing valve, which is shown in Depending on the load on the vehicle body, this sets a load-dependent pressure in a known manner is used for load-dependent braking.

In Figure 2 , a conventional spring bracket 2 is shown in connection with a conventional pendulum 4 on a widely known leaf spring. Instead of the pendulum 4, a conventional shake could also be provided.

When comparing the axle suspensions according to Figures 1 and 2 it is particularly clear that the conventional Spring bracket according to Figure 2 by a novelty with a Weighing device provided spring boc); can be replaced without having to attach to the vehicle body for the Spring bracket or something needs to be changed on the axle suspension.

A major advantage of the innovation is the possibility of an operationally reliable and easily accessible one Accommodation of the weighing valve.

In the preferred / _; As shown in the drawing, the angle lever is I-shaped, the two-sided T-legs of which engage through opposing slot-shaped openings 7 in the spring bracket 2 and with the pendulum 4 on one leg - is hinged. The T-shaped angle lever 6 remains practically at rest over the entire load range, since the control travel on the weighing valve is very small. (Approx. 0.5 mm). Because the angle lever 6 is able to support itself with its two-sided T-shaped legs in slot-shaped openings of the spring bracket at two points, it is able to accommodate transverse forces without straining its bolt-ring, which has sufficient play for this. This means that the angle lever can also be axially displaced on the bearing pin. The innovation ii «is not limited to the Viege valve device with leaf springs. Corresponding weighing valve devices according to the teaching of the innovation can easily be specified for rail vehicles with bogies.
