Abstract

The present invention concerns arrangements which are used on vehicle assemblies consisting of a pulling vehicle 1 and a trailed vehicle 3 and which fill the gap which occurs between these vehicles during travel and causes energy-consuming eddies of air to develop in these spaces. Such an arrangement consists of a balloon 8 arranged in the end wall 6 of the vehicle 3 and partly or completely filling the space. The balloon 8 can be inflated by means of a pressure medium system arranged in the vehicle. Its part directed away from the vehicle is secured in a frame 9 which defines the shape of the balloon and which is supported by at least one arm arranged in the said end wall of the vehicle. The arm can be telescopically extended and is provided with a spring device 11 for contracting the arm to a shortened state. <IMAGE>

Description

6 ~ 44gylika farthämmande luftvirvlar kunna helt eller delvis undvika: medelst en anordning enligt uppfinningen genom att mellanrummet mellan de båda fordonen helt eller delvis är uppfyllt av en upp- blåsbar ballong 8. Ballongen är fästad vid släpets 3 främre gavel 6. Ballongens främre del hålles utspänd av en ram 9, som uppbäres av en eller ett par i släpets tak nära gaveln 6 anordnade bärar- mar 10. Längden hos dessa bärarmar är så avpassad, att ramen 9 är belägen nära dragbilens l bakre gavel-7. 6 ~ 44 -like speed-inhibiting air vortices can be completely or partially avoided: by means of a device according to the invention in that the space between the two vehicles is completely or partially filled by an inflatable balloon 8. The balloon is attached to the front end of the trailer 3. The front part of the balloon is held stretched by a frame 9, which is supported by one or a pair of support arms 10 arranged in the roof of the trailer near the end 6, the length of these support arms is so adapted that the frame 9 is located near the rear end 7 of the tractor 1.

Såsom antydes i fig. 1 och 2 äro bärarmarnaalämpligen telesko- piskt förlängbara och påverkade av fjäderdon, lämpligen dragfjäd- rar ll, som sträva att förkorta bärarmarna.As indicated in Figs. 1 and 2, the carrier arms are suitably telescopically extendable and actuated by spring means, suitably tension springs 11, which strive to shorten the carrier arms.

Såsom antydes i fig. 1 och 2 medelst en slang 12, är ballongen ansluten till släpets tryckluftssystem, med hjälp av vilket slä- pets tryckluftsbromsar manövreras.Vid stillastående långtradare och tillslagna bromsar är tryckluftskällan frånkopplad och därmed trycket i ballongen, varvid dragfjädrarna ll drar samman bärarmar- na 10 och tar med sig ramen 9 mot släpets främre gavel 6. Man får härvid fritt tillträda till dragbilana 1 bakre gava1_7, arm kan 1 » öppnas för lossning ochlastning den vägen. Kan ramen 9_jämte den på tryckluft tömda ballongen svängas undan, erhåller man tillträ- de till släpets främre gavel 6. systemet. I samband härmed fylls ballongen 8 med tryckluft, varvid ballongens ram 9 förs i riktning mot dragbilen under utsträckning av bärarmarna 10 och utdragning av balldhgen, som nu helt eller .delvis kommer att utfylla mellanrummet mellan dragbilen 1 och släpetß.As indicated in Figs. 1 and 2 by means of a hose 12, the balloon is connected to the trailer's compressed air system, by means of which the trailer's compressed air brakes are operated. At stationary trucks and switched on brakes, the compressed air source is disconnected and thus the pressure in the balloon. the support arms 10 and take the frame 9 towards the front end 6 of the trailer. In this case, one can freely access the tractor 1 rear end 1, the arm 1 can be opened for unloading and loading that way. If the frame 9_and the balloon emptied of compressed air can be swung away, access to the front end of the trailer 6. the system is obtained. In connection with this, the balloon 8 is filled with compressed air, the balloon frame 9 being moved in the direction of the tractor while extending the support arms 10 and pulling out the balloon, which will now completely or partially fill the space between the tractor 1 and the trailer.

Skarpa svängar företas i huvudsak vid långsam färd med fordons- tåget, varvid ballongen trycks_ihop mot dragbilens 1 bakre gavel 7 på den sida, som är belägen i innerkurva,_och sväller upp på den sida¿ som är beïagen_i ytterknrva.Motsvarande sammandragning eller förlängning av bârarmarna äger härvid:nmn.Tryçket i ballong- men är vid låg fart reducerat bland annat beroende på små ventiler elleraeventuellt kantskodda hål 16 i ballongsidan, vilket underlät- tar svängningsproceduren. ß Även andra mellanrum såsom mellan fordon och marken kunna ut- fyllas medelst uppblåsbara ballonger lb såsom visas i fiå- 3- iataiiat rar till att tryakluftaayataa kan far närifragavaranda ändamål andra tryckmediesystem såsom avgassystemet användas.Sharp turns are made mainly during slow travel with the vehicle train, whereby the balloon is pressed together against the rear end 7 of the tractor 1 on the side, which is located in the inner curve, and swells up on the side, which is bent in the outer bend. Corresponding contraction or extension of the support arms has the following: nmn. The pressure in the balloon is reduced at low speed due to, among other things, small valves or possibly edge-coded holes 16 in the balloon side, which facilitates the oscillation procedure. ß Other gaps, such as between vehicles and the ground, can also be filled by means of inflatable balloons 1b as shown in the drawings so that the compressed air air can be used for other purposes by other pressure medium systems such as the exhaust system.
