Definitions
- the invention relates to a scattering vehicle, in particular winter service scattering vehicle, comprising a spreader with a grit container and a spreader, which has a spreading disc rotating about a substantially vertical axis for the fan-like spreading of grit from the grit container.
- Winter service spreaders of this type are usually set up so that they are able to disperse both so-called blunting grit - namely sand or SpHt - as well as detergents - especially salts - in a dry or moistened state by means of the spreading plate.
- road salt is often moistened before or during the scattering process with a dosed added liquid, the so-called brine, so it adheres better on the traffic areas and both during and after the scattering by the natural wind or the wind of the scattering vehicle or other vehicles much less Danger is exposed to being blown away.
- liquid spreader in which by means of the spreading plate only liquids are discharged.
- the quality of spreaders was evaluated and optimized as part of a standstill trial.
- the scatter pattern is observed behind a stationary vehicle.
- Such tests ignore the influence of the wind, which at high speeds causes even very large swirling and wandering effects, even with moistened spreading material. Therefore, the spread pattern is now being investigated behind a moving littering vehicle, with top speeds of more than 60 km / h being considered for use on motorways.
- the requirementwindleit characteristic may be formed as a flat or curved, from top front to back bottom inclined wall, as a hood-like wind tunnel or a shell-shaped hood with down-constricting shape.
- the downwardly directed air flow also influences the trajectory of the scattering material and thereby the scattering pattern that forms on the road surface, whereby this influence alters both with increasing travel speed due to the resulting increased airstream speed and with different types of scattering.
- An automatic control of theêtwindleit vom-positioning for adjusting the acting from the top of the grit fan wind to different speeds and to be discharged Streustoffart is very complex. It is therefore an object of the present invention to propose measures to eliminate as far as possible the swirling and drifting effects which are detrimental to the homogeneity of the scattering pattern and which occur as a result of the driving wind in the wake of a scattering vehicle.
- first "upper" wind that is to say the wind from above the grit container
- first "upper" guide element can serve for example a sinewindleitelement, as is basically known from the aforementioned DE 33 25 940 Cl.
- the upper airstream guided in the direction of the spreading plate is then diverted into the air flow parallel to the spreading plate rotation plane. It is intended to protect the grit compartments in particular from above-acting, but also from laterally acting air currents.
- a first variant for diverting the guided toward the scattering plate airstream provides a deflecting element, which is arranged so that at least a portion of the scattering plate zuleiteiteten upper airstream is deflected at about the height of the scattering plate in a direction of spreading plate rotation plane substantially parallel air flow.
- the parallel air flow preferably also covers the area above and below the spreading plate or may also be restricted to the area above and the area below the spreading plate.
- a clear effect can already be established if the parallel air flow generated by the deflecting element in the area of the spreading plate has a flow velocity which is within a tolerance range of ⁇ 50%, preferably ⁇ 30% of the vehicle driving speed (at a spreading vehicle running at 60 km / h ) lies.
- a substantially horizontal guide element for example a baffle, is provided for diverting the upper airstream guided in the direction of the spreading plate into a substantially parallel air flow to the spreading plate rotation plane, which is arranged above the spreading plate in such a way that at least a part of the in the direction of the top airflow guided to the spreading plate from above meets the horizontal guiding element.
- a horizontal guide element can also be provided below the spreading plate, wherein a guide element arranged below the spreading plate can only have comparatively small dimensions in order to avoid a collision with the scattering groove fan which is thrown off the spreading plate.
- the upper guide element can be extensively be formed and extend far back over the spreading plate.
- the horizontal guide element may be formed as a semicircle or half ellipse with a diameter corresponding to the vehicle width or the grit container width and extend horizontally from the vehicle end to the rear.
- the horizontal guide element prevents the directed from above on the spreading plate upper airstream detected the grit fan. Instead, this air flow is discharged essentially horizontally via the horizontal guide element. This results in a plane of air substantially parallel to the scatter plate rotation plane above the grit fan.
- the horizontal discharge of the air flow over the horizontal guide element can advantageously be supported by a curved or inclined deflection section on the vehicle-side end of the horizontal guide element. As a result, flow losses are reduced, so that a higher flow velocity can be achieved over the horizontal guide element. The greater the flow velocity, the better the scattered grit fan underneath is shielded against currents acting from above and from the side.
- dissipation elements are preferably provided which decomposes the substantially parallel air flow into partial flows.
- flow structures acting in a direction transverse to the main flow direction are interrupted.
- the wake flow can be broken down into a multiplicity of small vortex braids, which disintegrate comparatively quickly and thus the spread pattern is minimized. influence.
- these dissipation elements are oriented approximately radially, so that the flow field is fanned out and the grit compartments are surrounded by a flow fan.
- the two above-mentioned variants for generating an essentially parallel to the Streutellerrota- air flow from the redirected upper airstream can be advantageously realized in combination by passing a portion of the redirected upper airflow from above to the horizontal guide element and is derived from this horizontally and a another part of the redirected upper airstream is led to below the horizontal guide element and is deflected there into a flow of air substantially parallel to the spreading plate rotation plane.
- the upper guide element may for example be tubular, so that the upper airstream is passed through the upper guide element, or shell-like, as is known for example from DE 3325940 Cl.
- the effect of the upper guide element can be enhanced. In this way, the flow velocity of the parallel air flow, which adjusts in the region of the spreading plate, can be influenced within wide limits.
- one or more turbomachines may be provided be.
- a turbomachine can serve to generate an air flow along the upper guide element.
- the turbomachine is preferably arranged approximately in the direction of the spreading plate in the direction of travel in front of the spreading plate. In corresponding test series, it can be determined in each case with what power the turbomachine has to be operated at a predetermined driving speed in order to achieve the desired flow velocity of the parallel air flow in the area of the spreading disc.
- a transversely oriented guide which scoops an air flow in the front region of the vehicle above the vehicle cab and selectively directed to the upper baffle. It has been shown that the flow velocity of the wind is immediately above the grit container comparatively low. With the help of the transversely oriented guide element above the cab, however, the upper guide element can be set comparatively low. The overall height of the vehicle can be kept lower, and also aesthetically makes a better impression.
- the guide element oriented transversely to the driver's cab is pivotable about a horizontal axis and / or adjustable in height in order to be able to adapt it to different spreading vehicles and different spreading material containers placed on the spreading vehicle.
- a lateral lining between the transversely oriented guide element above the driver's cab and the upper guide element for diverting the upper airstream may be conducive to the targeted supply of the air stream skimmed in the front region of the vehicle to the upper guide element.
- a brine supply line for supplying brine may be provided in the upper airstream guided by the upper guide element. Similar to the devices for deicing aircraft wings before take-off, the sprayed brine, with a corresponding droplet size distribution, impinges on the horizontal guide element from above and migrates on the guide element as liquid film predominantly to the trailing edge of the guide element. As a result, icing of the horizontal guide element is prevented.
- a wind deflector may be provided at the vehicle end in the direction of travel in front of the scattering plate for blocking vehicle under-floor wind. This is particularly advantageous in connection with the first variant described above, according to which at least part of the upper airstream is deflected into a parallel air flow at the level of the spreading plate.
- This parallel air flow can be kept more independent of undefined and usually turbulent air flows below the vehicle by means of the wind deflector. Accordingly, it is advantageous to extend the wind deflector substantially over the entire vehicle width. He should not reach to the ground. It is sufficient if the air flow flowing under the vehicle is significantly accelerated by the wind deflector. On the other hand, if the deflector reaches the ground, the entire air volume must be diverted from the upper airstream to flow around the spreader plate. This is difficult. In any case it is expedient to make the wind deflector adjustable at least in height, so as to be able to adapt it to optimum operating conditions and to different vehicle types individually.
- this nozzle can suck in and accelerate wind from underneath the vehicle and blow air flow over and / or under the grit fan compartments protecting the grit fan compartments.
- a flow device whose opening is located with a large cross-section in the direction of travel to detect ground-level wind, and whose smaller outlet opening is opposite to the direction of travel, the cross-section of the nozzle according to the geometry of a Laval nozzle preferably passes from the inlet to the outlet opening a minimum ,
- the componentswindleittoxins on the right and left next to the grit container each comprise at least one lateral guide element, which are arranged such that they Detect lateral wind, then from its downstream ends to the rear, d. H. against the direction of travel, can flow.
- the lateral airflow is not directed downwards onto the spreading fan, as is the case with the prior art described at the outset, but the lateral guide elements have primarily the function of to separate the airstream into partial flows.
- Experiments have shown that can be at least significantly reduce the spherical structures of the Nachonneverwirbelungen in this way, making it possible to keep the homogeneity of the scattered scattered image despite increased speed approximately the same.
- the lateral guide elements deflect the lateral airflow toward the spreader or vehicle center.
- they can be wing-shaped. By deflecting the lateral airstream towards the center into the wake of the scattering vehicle, the width of the dead water area in the air flow behind the vehicle can be significantly reduced and, as a result, the size and energy of the eddy bales.
- Guiding element is provided, which is arranged behind the vehicle approximately centrally to the grit container and aligned in the direction of travel.
- the vertical guide element can be arranged, for example, on the surface of the horizontal guide element facing away from the spreading plate. Especially In the direction of travel, the vertical guide element can extend far beyond the scattering plate and beyond the horizontal guide element. By means of the vertical guide element, the flow field can be stabilized behind the vehicle and avoid a pronounced vortex street.
- the first guide elements In order to prevent the andwindleitinci, be it the lateral guide elements, the upper guide element, the vertical guide element behind the vehicle, the transversely oriented guide element above the cab or the horizontal guide element above the spreading plate, freeze, are one or more of these sincewindleit vom.
- the beforewindleit vom may be formed as a hollow body, so that they are heated from the inside.
- the hollow body can be flowed through with a warm medium, wherein as the warm medium preferably the exhaust gases of the winter utility vehicle can be used.
- the hollow body can be directly or indirectly connected to the exhaust system of a winter maintenance vehicle.
- Another way to avoid ice deposition is to pressurize the cavities at intervals with air pressure from the brake system. As a result, the surface expands so that ice deposits flake off.

The position and shape of scattering plate 10 and downpipe 17 are therefore only in Fig. 2 shown schematically.
- the flow field 12 is significantly enhanced by the combination of the horizontal baffle 11 with the upper guide vanes 19, so in that a flow that protects the grit compartments and that is essentially parallel thereto adjusts itself.
- the vertical guide surface 16 has the function of attenuating a vortex road behind the vehicle by preventing the interaction of the shear layers separating at the vertical rear edges of the vehicle from each other and converting the two-sided vortex shedding into two one-sided detachments.
