Abstract

To provide a device (1) for clearing snow from a lane of a vehicle having at least one mouldboard (2, 3) and attachment means (7) for securing the device to the vehicle which generates a bow wave during travel of the vehicle, also is at high speeds below a maximum permissible value, at the same time a sufficiently good clearing of the snow is achieved by the roadway, it is proposed that at least one mouldboard (2, 3) air outlets (6) for reducing the air resistance is formed.

Description

The The invention relates to a device for clearing snow from a roadway of a vehicle with at least one mouldboard and attachment means for securing the device to the vehicle.

Such a device is for example from the CH 126 351 already known. The snow remover shown there has two wedge-shaped mouldboards and is intended for mounting on a rail vehicle.

About that In addition, mats are known, which are attached to high-speed rail vehicles are. At high speeds, the device generates a high-speed vehicle Bow wave, so that a maximum allowable pressure exceeded becomes. There are therefore already miniaturized devices, too used as snow clearers, used, whereby However, the snow on the road is not adequately eliminated.

task The invention is therefore an apparatus of the aforementioned To provide a type that produces a bow wave, even at high Speeds of the vehicle below a permissible Maximum value, while at the same time sufficiently good clearing of the snow is provided by the roadway.

The Invention solves this problem in that at least one Mouldboard air outlets to reduce air resistance formed.

The Device according to the invention has air outlets on, which reduce the air resistance of the device. There are the air outlets according to the invention so arranged that sufficient clearing of the snow is possible. For example, if there is powder snow, so ensure the airtight and the air-permeable Sections of each mouldboard for sputtering the powder snow and thus for a sufficiently good stripping from the roadway. In the case of Pappschnee, however, it comes through the air-impermeable sections when clearing to a thickening, the snow has a strength, which allows any mouldboard, despite the air outlets, this to strip off the roadway. Within the scope of the invention one or more mats are used. The order the mouldboard is basically arbitrary.

advantageously, the air outlets are limited by Abstreifstege. Such Wiper bars are easy to produce and have a sufficiently high mechanical strength.

advantageously, has the device according to the invention over two mouldboards, which are aligned wedge-shaped are, wherein the Abstreifstege on the opposite sides of the Mouldboards are arranged.

According to one Advantageous further development are the mouldboard in their mutually connected side, so that a wedge tip is trained. Deviating from this limit the mouldboard an air gap that allows the passage of snow in the middle area allows the device.

The Abstreifstege extend appropriately in the longitudinal direction of the mouldboard and expediently from the outermost in a plan view Side of the respective mouldboard inside. The snow is thus from the inside, central and airtight Area of the mouldboard detected, transported to the outside and thickened. The thickened snow reaches the scraper bars, whose distance is small enough to prevent the snow from being blown off ensure air resistance due to the between the Abstreifstegen trained air outlets, however is lowered.

According to one preferred embodiment of the invention form the mouldboard each having a first portion and a second portion, wherein the first sections regarding the intersection of their imaginary longitudinal axes a larger angle span than the second sections with respect to the point of intersection their longitudinal axes. In other words, the second ones Sections angularly attached to the respective associated section. The second sections are arranged sharper than the first sections. The device thus enters less quickly in a plan view the width and forms a low air resistance.

Further expedient refinements and advantages of the invention are the subject of the following description of embodiments of the Invention with reference to the figure of the drawing, wherein the

Figure a preferred embodiment of the device according to the invention 1 shows.

The device shown in the figure 1 has a first mouldboard 2 and a second mouldboard 3 on. Each of the mats 2 . 3 has a first section 2a respectively 3a as well as a second section 2 B respectively 3b , where the first sections 2a . 3a forming a connecting edge 4 or ploughshare are interconnected. The mouldboard 2 and 3 are thus arranged wedge-shaped.

The connecting edge 4 engages while driving a rail vehicle to which the device 1 is fastened in use, under the snow and parts of it, the mats provide for stripping the snow from the road.

Each of the second section 2 B respectively 3b has scraper bars 5 that are at the of the respective first section 2a respectively 3a opposite side of the second section 2 B respectively 3b extend in the longitudinal direction, ie in the direction of travel, to the outside. This limit the Abstreifstege 5 air outlets 6 that allows air to pass through the mats 2 . 3 enable. Further, the second sections 2 B respectively 3b angled with respect to the respective first section 2a respectively 3a arranged. By going through each of the second sections 2 B . 3b and through each of the first sections 2a . 3a a longitudinal axis, so stretch the imaginary longitudinal axes of the second sections 2 B respectively 3b with respect to their point of intersection a smaller angle than the imaginary longitudinal axes of the first sections 2a respectively 3a with respect to their point of intersection, here with the connecting edge 4 coincides. In other words, the second sections 2 B respectively 3b sharpener aligned than the first sections 2a respectively 3a , This leads to a reduced air resistance, with the blunter arrangement of the first sections 2a . 3a a sufficiently high thickening of the snow bereitge provides, so that this despite the air outlets 6 can be safely removed from a roadway. The size of the air outlets 6 is adapted to the degree of the achievable compaction of the snow. A fall of snow through the air vents 6 can thus be excluded as far as possible. At the same time, the air resistance of the device 1 reduced by the more pointed alignment of the second sections to each other.

For fixing the device 1 on the vehicle serve fastening means, the three holding units 8th . 9 and 10 include. The holding units 8th and 10 are at the free end of the mouldboard ( 2 . 3 ) firmly with the Abstreifstegen 5 connected and thus provide additional stabilization for the Abstreifstege 5 ready. Each of the holding units 8th . 9 respectively 10 has long holes 11 on, with which the device 1 is attached to a vehicle and in particular to a rail vehicle. By aligning the slots 11 in the direction of travel are the vehicle and the device 1 better protected from damage, as the holder of the device 1 At the vehicle from a certain preload force can give something. A height adjustment to compensate for a wheel wear is, for example, by vertical slots in the counterpart of the mounting units 8th . 9 or 10 provided.

As already stated above, clearing of snow from a roadway by the device 1 despite the air outlets 6 allows. The device is mounted as a snow eraser advantageously in the direction of travel before all axles lying down on the vehicle, so that the device while driving at a small distance on the road grazes. Powder snow lying on a road surface is atomized and carried away by the air flow. In so-called Pappschnee this is through the first sections 2a respectively 3a in the middle part of the device 1 compressed, split in the middle and then slides laterally on the respective mouldboard 2 respectively 3 along. Due to the compression, the snow has become so firm that it can not pass through the air outlets 6 can be pushed through it, but further slides to the outside.
