Definitions
- the invention relates to a sanding device for sand spreading systems for vehicles, in particular for rail vehicles, for connection to at least one sand scatter line to the vehicle wheel, with at least one sand bell protruding from below into a sandpit, one Compressed air connection, a sand outlet, and one adjacent to the sand bell in the sandpit attached heating cartridge, and a sand spreading system for vehicles, especially for rail vehicles, with at least one sandpit and at least two sand scattering lines, which in Guide the direction of travel in front of and behind the vehicle wheel.
- the sand spreading systems require considerable space, especially for the sandpit with the Sanding facility.
- This object is achieved in that at least two sand bells, two sand outlets for connection to a sand scattering line and two separate compressed air connections, and only one heating cartridge is provided. So that with only one, structural relatively compact sanding device, less wiring and also assembly effort needs to supply two sand scattering lines, which means that the space is required despite great flexibility can be kept low in application.
- the sanding device according to the invention can advantageously be installed in very narrow sandboxes, so that they are special can be used in low-floor vehicles, in particular with portal undercarriages.
- all sand bells are adjacent to the one heating cartridge arranged. Through the one heating cartridge, around which all sand bells are arranged, can clump the sand around without any additional wiring work all discharge openings are prevented.
- the two compressed air connections of a control device are advantageously separate or optional control so that despite the compactness of the device sand can be discharged from only one sand scattering line at a time. This is an economical one Handling of this material and long refill intervals given.
- control devices are solenoid valves educated. This version allows easy control and simple actuation Activation of the sand discharge from one scatter line each with a compact design.
- control devices have a control line connected, one of the two control devices according to the direction of travel of the vehicle activated. Via this control line, signals dependent on the direction of travel, for many vehicle types, simply from the existing control electronics of the vehicle can be derived, the compressed air connection is activated automatically, that for supplying the stray line ending in front of the wheel in the respective direction of travel is provided.
- FIG. 1 shows a front view of a sand spreading system according to one embodiment of the present invention, installed in a portal chassis of a low-floor rail vehicle
- Fig. 2 is a side view from the outside of the chassis of Fig. 1 with the Sand spreading system
- Fig. 3 is a side view of an embodiment of an inventive Sanding device
- Fig. 4 is a side view of the sanding device of Fig. 3, from a direction different by 90 °
- FIG. 5 is a side view of a sand bell with Compressed air connection and introduction of a sanding device according to the invention in enlarged Scale, partially cut.
- a portal chassis is shown schematically, as it is in modern low-floor rail vehicles, especially for local transport, is used and because of the cramped space especially a sand spreading system according to the present invention is advantageous.
- an idler gear which is suspended via a primary suspension 2 is driven by a motor-gear unit 3.
- the inner boundary of the car body with its lowered floor is 4, by a cladding of the portal landing gear
- the outer boundary formed is marked with 5.
- the car body is over one Secondary suspension 6 supported with dampers. 2 the directions of travel for the forward or reversing symbolized by arrows with the letters "V" and "R".
- Sandpit 7 advantageously adapts in shape to the course of the inner boundary 4 of the car body and has on its top a filling opening 8 for the introduction of the scattering material - preferably fine quartz sand - and preferably one further opening 9.
- the sandpit 7 is essentially vertical above the wheel 1 arranged. From a likewise above the wheel 1 in the lower part of the sandpit 7, preferably in a section of its bottom, built-in sanding device 10, the will be described in detail below, lead two connecting pieces 11, 12 down directed away, to which the two sand scatter lines 13, 14 are connected.
- the sanding device 10 shown in detail in FIGS. 3 and 4, exists essentially a base plate 20, preferably an aluminum block, with holes 21 for carrying out, for example, four fastening screws 22 with which the Sanding device 10 fastened in or under a cutout in the sandpit 7 of the installation can be.
- the connecting pieces 11 and 12 for connection to the sand scattering lines 13, 14 are each connected to two adjacent sand outlets 23, 24, which over in each case one in the sandpit 7 from below protruding sand bell 25, 26 located therein Peel off sand.
- each sand outlet 23, 24 27 or 28 connected there is a compressed air connection with each sand outlet 23, 24 27 or 28 connected, blown in via the compressed air and thereby - how to continue is explained in more detail below in connection with FIG. 5 - below the sand bells 25, 26 Vacuum can be created.
- the clumping of the sand in the area of the sand bells 25, 26 can be provided by a heating cartridge projecting into the sandpit 7 adjacent to it 29 can be prevented, which advantageously via heat-resistant silicone cable 30 with electricity is supplied.
- any suitable control means can be used to ensure that each of the two compressed air connections 27, 28 separately, i.e. optionally be supplied with compressed air from the other connection can, so that depending on requirements only from one of the two sand pipes 15 or 16, of course from the sand pipe, sand, lying in front of wheel 1 in the direction of travel. is carried out.
- the two compressed air connections 27, 28 are preferably electrical or electronically controllable valves, preferably with a changeover solenoid valve, Mistake. This magnetic valve is preferably switched over automatically by deriving a control signal representing the direction of travel, which for example comes from the normal control electronics of the vehicle.
- the sand bell 25 is inclined entry bore 31 running upwards, which is at the highest point of the sand bell 25 merges into an essentially vertically downward channel 32.
- the area of this channel 32, slightly above the sand outlet 23, is in the wall of the channel 32 at least one bore directed obliquely downwards and towards the center of the channel 33 is provided, preferably a whole group of substantially around the circumference of the Channel 32 equally distributed bores 33.
- Compressed air supply bore 35 is air under high pressure into a via a nozzle 36 the lower region of the channel 32 with the bores 33 in a ring surrounding chamber 37 fed. This then enters through the bores 33 in the channel 32 and creates one down, i.e. in the connecting piece, directed air flow, which in turn in the upper Area of the channel 32 and in the inlet bore 31 of the sand bell causes a negative pressure, which sucks the sand from the area around the sand bell 25 and further into the Channel 32 promotes.
- the compressed air conveys the sand further into the connecting piece 11, the line 13 and finally from the sand pipe 15 in front of the wheel 1.
- the nozzle 36 is for maintenance and accessible for exchange via the screw plug 34.
