Definitions
- the invention relates to a sand spreading device for Rail vehicles, especially low-floor light rail vehicles, essentially consisting of a vehicle body assigned sand storage container, a dosing device, a sand outlet near the wheel and a flexible line for connecting the Sand storage container with the sand outlet.
- Sand spreading devices with the aforementioned features are in numerous versions for rail vehicles in use. Such devices can be used as falling sand spreaders work, d. that is, the sand flows after activation the dosing device on or in the vehicle body located sand reservoir by the flexible lines (hoses) to the wheel side Sand leakage.
- a prerequisite for a reliable function Operation of such sand spreading equipment is in a relatively steep arrangement of the flexible lines, that in high-floor vehicles with a floor height of, for example, 1000 mm above the top edge of the rail is usually executable without difficulty.
- At Vehicles with a floor height of the order of magnitude of only 400 mm above the top edge of the rail it is because of the Space is not possible, however, the flexible Lay pipes with the required gradient, see above that the sand flow can be disturbed by blockages.
- the invention is therefore based on the object Sand spreading device of the generic type for one reliable use even with rail vehicles low-lying floor.
- This object is achieved in that the sand outlet combined with the metering device Sand tank is assigned to a smaller one Has volume than the sand reservoir.
- the vehicle body 2 is a sand reservoir 1 assigned to the interior of the vehicle body 2 can be located below a passenger seat.
- the sand storage container 1 tapers downwards funnel-shaped.
- a wheel 8 shown in FIGS. 1 and 2 belongs to one for example four-wheel chassis on which the vehicle body 2 supported in a manner not shown here is. Near the wheels 8 and as low as possible Height above the top edge of the rail 7 is one with a Dosing device 6 (see Fig. 3) combined sand container 4 attached to a chassis beam 5. Preferably in addition to this sand container 4 is also on Chassis bracket 5 held compressed air generating device 9, e.g. B. a small compressor arranged.
- the vehicle side Sand storage container 1 and the wheel-side sand container 4 with metering device 6 are each through a flexible line 3 (hose) connected to each other.
- Dosing device 6 works according to the Venturi principle.
- the metering device 6 can also be used as Sand stairs or injection nozzle can be designed.
- sand is extracted from the Sand container 4 to a located in the vicinity of the wheel 8 Sand outlet 11 using the compressed air generating Device 9, which is connected to the air inlet 10.
- Both the sand container 4 with metering device 6 as the sand outlet 11 are also preferably heated.
- the sand gets out of the sand reservoir by gravity 1 and the flexible line 3 in each of the wheel-side sand container 4, for example 1 liter Takes up sand.
