Definitions
- the invention relates to a sand spreading device, in particular for rail vehicles, with one in the range Wheel arranged sand outlet that is at a distance ends above the rail.
- a sand spreading device with the aforementioned features is generally known in rail vehicles.
- the sand outlet is usually one on the frame, for example Chassis held.
- the Rail-ending sand outlet can be in the driving mode Splash water penetrate with the unfavorable consequence of a Grabs the sand outlet.
- the invention has for its object a sand spreading device of the generic type in particular simple and inexpensive way in terms of Scattering effect and reliability in operation too under unfavorable weather conditions (heavy rain, Frost).
- This object is achieved in that the sand outlet from an inner tube and from one outer tube is formed, the inner tube being shorter is executed as the outer tube and in this outer Pipe opens.
- the object of the invention is advantageous achieved that the whirled up while driving Moisture collects on the inside of the outer tube and drains down without the back pressure into that inner pipe of the sand outlet to be pressed. Thereby the grit sand gets stuck in the inner tube reliably prevented.
- the drawing shows the lower one Area of a rail vehicle with a sand spreading device.
- a sand outlet 1 belongs to the sand spreading device on a suspension primarily against a wheel 2 Frame part 5 is screwed.
- the one with a sand spreader usual other assemblies - such as storage containers and dosing device - are omitted here because their respective execution of the invention independently is.
- the sand outlet 1 consists of an inner tube 1a and from an outer tube 1b, the inner tube 1a (Conveyor pipe) - if necessary with the interposition of a Hose line - with the reservoir or the Dosing device is connected.
- the inner tube 1a is shorter executed as the outer tube 1b and opens into this outer tube 1b. Whirled up moisture collects on the inside of the outer tube 1b and then runs down freely.
- the sand outlet 4 is made of elastic Material, e.g. B. rubber, existing shield 4 such assigned that a occurring especially in grooved rails Bow wave is rejected.
- elastic Material e.g. B. rubber
- existing shield 4 such assigned that a occurring especially in grooved rails Bow wave is rejected.
- sand outlet 1 and possibly also Hose line through preferably self-regulating heating elements be heated.
