Abstract

The beam formation (6) is mounted on the chassis part (3) of a vehicle. The beam can be tilted between a loading position in which it slopes downwards and outwards towards the ground at the rear end of the vehicle and a transport position in which it slopes downwards and inwards towards the driving cab (2). The beam formation has rollers (9) or other slide components which work in conjunction with a load supporting section (14) which is displaceable along the formation and tiltable with it. In the transport position, the beam formation is so raised at the rear end of the vehicle that a vehicle suspension fork (13) can support a vehicle or other load partly below the load-bearing section.

Description

455 740 FIG. 5 visar lastbehållare under lastning på fordonet. 455 740 FIG. 5 shows cargo containers during loading on the vehicle.

Fordonet enligt uppfinningen utgöres grundläggande av en lastbil l där motorn är inbyggd i förarhytten 2, för att lastbilen skall bli så kort som möjligt. Det som konventionellt kallas lastflak utgöres här av en chassiedel 3, som sträcker sig från förarhytten 2 bakåt ett stycke förbi det bakre hjulparet 4. Chassiedelen 3 har ungefär på mitten av dess längdutsträckning en vippa S, som ligger högre än chassiedelens 3 främre och bakre ändar. Vid vippan 5 är en stegeliknande balkkonstruktion 6 svängbart fastsatt, så att denna kan lutas antingen bakåt-nedåt eller framåt-nedåt.The vehicle according to the invention basically consists of a truck 1 where the engine is built into the cab 2, in order for the truck to be as short as possible. What is conventionally called the load platform here consists of a chassis part 3, which extends from the cab 2 backwards a bit past the rear wheel pair 4. The chassis part 3 has approximately in the middle of its longitudinal extent a rocker S, which is higher than the front and rear ends of the chassis part 3 . At the rocker 5 a step-like beam structure 6 is pivotally attached, so that it can be tilted either backwards-downwards or forwards-downwards.

Den stegeliknande balkkonstruktionen 6 består av två parallella balkar 7, vilka är förbundna genom tvärstag 8. Vid balkarna är en uppsättning rullar 9 fastsatta. Intill förarhytten 2 finns ett motordrivet spel 10.The step-like beam structure 6 consists of two parallel beams 7, which are connected by cross struts 8. A set of rollers 9 is attached to the beams. Next to the cab 2 is a motorized game 10.

Vid chassiedelens 3 bakre ände finns en.utdragbar stång ll, vid vilken en kompletterande rulldel 12, en bilupphängnings- gaffel 13 eller liknande är fastsättbara. På balkkonstruktio- nen 6 kan olika utrustningar dras upp från marken eller annat underlag med hjälp av spelet 10. Ett exempel på sådan utrustning utgöres av flaket 14, som på undersidan har skenor, som styres av och rullar mot rullarna 9 på balkkonstruktionen 6.At the rear end of the chassis part 3 there is a pull-out rod 11, to which a complementary roller part 12, a car suspension fork 13 or the like can be attached. On the beam structure 6, various equipment can be pulled up from the ground or other surface by means of the clearance 10. An example of such equipment is the platform 14, which on the underside has rails, which are guided by and roll against the rollers 9 on the beam structure 6.

Enligt fig. 2 har balkkonstruktionen 6 fällts så. att den lutar bakåt-nedåt och flaket 14 har placerats i anslutning till denna för att kunna dras upp på balkkonstruktionen 6 med hjälp av spelet-10. En personbil 15 är i läge att föras upp på flaket 14 och en vajer 16 sträcker sig mellan bilen 15 och spelet 10. När spelet 10 spelar in vajern 16 dras bilen 15 först upp på flaket 14 och när bilens 15 framhjul 17 slår mot en främre tvärbalk 18 på flaket l4 följer flaket 14 med upp på 453 740 balkkonstruktionen 6.According to Fig. 2, the beam structure 6 has been folded as follows. that it slopes backwards and downwards and the platform 14 has been placed adjacent to it in order to be able to be pulled up on the beam structure 6 by means of the clearance-10. A passenger car 15 is in a position to be brought up on the platform 14 and a wire 16 extends between the car 15 and the winch 10. When the winch 10 records the wire 16, the car 15 is first pulled up on the platform 14 and when the front wheel 17 of the car 15 strikes a front cross member 18 on the platform 14 follows the platform 14 up to the beam structure 6.

När balkkonstruktionen 6 kommit så långt fram mot förarhytten 2 som möjligt låses flaket 14 fast vid balkkonstruktionen 6 med hjälp av icke visade lås. Lämpligtvis låses även bilen 15 fast vid flaket 14. Flaket 14 tippas därefter över till det i fig. 3 visade läget, vilken tippning utföres på hydraulisk eller annan passande väg.When the beam structure 6 has come as far forward towards the cab 2 as possible, the platform 14 is locked to the beam structure 6 by means of locks (not shown). Suitably, the car 15 is also locked to the platform 14. The platform 14 is then tipped over to the position shown in Fig. 3, which tipping is performed by hydraulic or other suitable way.

En andra bil 19 fästes sedan i vajern 16 eller i någon annan från spelet 10 utgående vajer och bilen 19 spelas in så att dess framhjul 20 kommer i läge i upphängningsgaffeln 13, varefter stången ll lyftes på konventionellt sätt. Fig. 4 visar det lastade ekipaget, varvid det för uppfinningen speciella framgår, nämligen att den släpade eller bogserade bilen 19 har en del av sitt framparti under flaket 14 och under den på detta placerade bilen l5. Härigenom blir ekipaget kort trots att det transporterar två bilar.A second car 19 is then attached to the wire 16 or to another wire coming out of the winch 10 and the car 19 is recorded so that its front wheel 20 is in position in the suspension fork 13, after which the rod 11 is lifted in a conventional manner. Fig. 4 shows the loaded carriage, whereby it is special for the invention, namely that the towed or towed car 19 has a part of its front part under the platform 14 and under the car 15 placed thereon. This shortens the crew even though it transports two cars.

Fig. 5 visar två godsbehâllare 21, 22 r under lastning på samma sätt som det tidigare flaket 14, och dessa godsbehâllare 21, 22 har skenor motsvarande de på flaket 14, vilka skenor samverkar med rullarna 9 på balkkonstruktionen 6.Man inser att i detta fall en bil kan släpas på samma sätt som enligt fig. 4, men på chassiedelen 3 uppbäres en annan last än en bil, t.ex. de visade godsbehållarna. Detta gör fordonet enligt denna uppfinning mångsidigt användbart.Fig. 5 shows two freight containers 21, 22 r during loading in the same way as the previous flatbed 14, and these freight containers 21, 22 have rails corresponding to those on the flatbed 14, which rails cooperate with the rollers 9 on the beam structure 6. It will be appreciated that in this case a car can be towed in the same way as in Fig. 4, but on the chassis part 3 a load other than a car is supported, e.g. they showed the goods containers. This makes the vehicle of this invention versatile.

För fackmän på detta område torde många olika tillämpningar för fordonet enligt denna uppfinning vara möjliga. Dessa tillämpningar är emellertid avsedda att ligga inom ramen för de bifogade patentkraven.Many different applications for the vehicle according to this invention will be possible for those skilled in the art. However, these applications are intended to be within the scope of the appended claims.
