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

The invention relates to a weighing device for load-dependent, brakable rail vehicles, the The vehicle body is suspended or supported by a pendulum or hook on the vehicle suspension.

The object of the invention 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 can be retrofitted to the axle suspension in a particularly simple manner. The Weighing device according to the invention be housed largely operationally safe and easily accessible.

According to the invention, the object is achieved in such a way 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 connected to one held on the vehicle Weighing valve is in communication. A preferred embodiment of the invention is 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 mounted, one of which with a Schake odex ·: a pendulum on one side of the vehicle suspension in Connected arm through an opening in the wall of the spring bocke "groiJt and deeyeri others with it the weighing valve in verb iiKlunf; ! standing Ana in the

Extends cavity of the spring bracket.

The angle lever for absorbing transverse forces can advantageously be T-shaped, with the two-sided T legs of the angle lever from _; one of which is articulated to the axle spring suspension through opposite slot-shaped openings in the wall. grab the feather-oekes,.

^ Furthermore, the spring bracket can advantageously be designed to be screwed onto the floor of the vehicle body, the fastening bolts reaching through openings in the floor of the vehicle body for screwing on conventional spring brackets. The angle lever is advantageously arranged and designed on the spring bracket in such a way that a conventional shackle or a conventional pendulum in connection with a conventional vehicle suspension can be articulated at the end of one arm. . _; .

The invention is described using an exemplary embodiment, which is shown schematically in the accompanying drawing. Herein shows:

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

Angle lever T-shaped, its bilateral T-legs through opposite slit-shaped .Openings 7 grip in the spring bracket 2 and where on the one leg the pendulum 4 is articulated. The T-shaped one Angle lever 6 remains practical over the entire load range at rest, as the control travel on the weighing valve is very short are. (Approx. 0.5 mm). The fact that the angle lever 6 with its two-sided T-shaped legs-in-slot-shaped openings of the spring bracket able to support at two points, it is able to absorb transverse forces without loading its pin bearing, which is necessary for this; . ·. has sufficient play. So that the angle lever on the bearing pin is also axially displaceable .. The Invention is not based on weighing valve device with leaf springs limited. Corresponding weighing valve devices according to the teaching of the invention can easily be used for rail vehicles with bogies indicate. . - ·. ; ':
