Problems solved by technology

This due to atmospheric influences can lead to humidity, temperatures below the dew point and freezing in bulk material spreading systems and compressed air systems
As a result, blockages of the sand conveying pipes can form during the operation of the bulk material spreading plant, which can lead to agglomeration or freezing of the spreading medium in the conveying pipes and thus can lead to malfunctions or even shutdowns of the plant

Embodiment Construction

[0020] figure 1 and figure 2 A schematic illustration of an exemplary embodiment of a bulk material spreading device 10 according to the invention and a schematically indicated rail vehicle in the form of a vehicle wheel and a vehicle track is shown.

[0021] The device 10 comprises: a storage container 1 that can be filled with bulk material; a loose element 2 associated with the spreading opening of the storage container 1; at least one spreading duct 5 for the bulk material, which ends immediately between the tire 20 and the track 30 The gap between 40. It can be seen from the sectional view shown in the figure that a metering unit 3 and a conveying element 4 connected to the metering unit 3 are arranged downstream of the loose element 2, wherein the conveying element 4 is connected with the shut-off and inlet valve 7 and the spreading pipe 5 connected. The loose element 2 , the metering unit 3 and the conveying element 4 are connected to one another via a common drive ...

Abstract

The invention relates to a scattering-material dispensing system for vehicles, in particular rail vehicles, and a method for dispensing scattering material from such a system. The scattering-material dispensing system comprises a reservoir (1) that can be filled with scattering material, a loosening element (2) associated with the dispensing opening of the reservoir (1), and at least one dispensing line (5) for the scattering material ending in the immediate vicinity of a rim / rail gap, wherein a metering unit (3) and a conveying element (4) connected to the metering unit (3) are arranged downstream of the loosening element (2), wherein the conveying element (4) is connected to a shut-off and supply-air valve (7) and a dispensing line (5).

Description

technical field [0001] The invention relates to a bulk material spreading device for a vehicle, in particular a rail vehicle, and a method for spreading bulk material by means of a bulk material spreading device. [0002] Such devices and methods are of increasing importance as part of braking systems for increasing the static friction between tires and rails in rail vehicles. Background technique [0003] Various bulk material spreading devices for rail vehicles are known from the prior art. Bulk material spreading plants of this type usually have a spreading unit and a storage container, which is filled with sand and from which the sand is transported via the spreading unit to the track to the rail vehicle tires by means of different methods in order to improve the The traction of the rail vehicle during starting and braking. In the simplest embodiment, a device of the described type consists of a sand box from which loose sand is scattered by gravity via the downcomer o...
