Description

4 5 7 3 4 5 'z Genom att utnyttja tvâ i huvudsak identiska, stående plattjärn med mellan- liggande distanser som icke vridstyv främre profil, möjliggöres en enkel och stabil infästning av framhjulsupphängningarna mellan plattjärnen. 4 5 7 3 4 5 'z By using two essentially identical, standing flat irons with intermediate horizontal distances such as non-torsionally rigid front profile, a simple and stable attachment of the front wheel suspensions between the flat irons.

Vid den bakre profilen är det ändamålsenligt att fästa bar-organ för kaross- infästning samt för motoraggregat.At the rear profile it is expedient to attach bar members for the body. mounting and for motor units.

Genom att låta rören förbindande de båda icke vridstyva prof ilerna passera i nära anslutning till ett i karossen utformat säte, kommer en belastning pâ sätet som ger en nedfjädring av detta, att tagas upp av roren, vilket förhin- drar en ogynnsam deformation av karossen, vilket i sin tur innebär, att denna kan göras tunnare.By passing the pipes connecting the two non-torsionally rigid profiles in close proximity to a seat designed in the body, a load comes on the seat which provides a suspension thereof, to be taken up by the rudders, which prevents pulls an unfavorable deformation of the body, which in turn means that this can be made thinner.

Genom att hänga upp eller 'skjuta på en batterihållare på de båda rören som förbinder de båda icke vridstyva profilerna, f år batteriernayars vikt kan utgöra ca hälften av fordonets totalvikt, en mycket gynnsamt låg och central placering och blir dessutom lätt åtkomliga för utbyte.By hanging or sliding on a battery holder on the two pipes as connects the two non-torsionally rigid profiles, f if the weight of the battery nays can make up about half of the vehicle's total weight, a very favorable low and central placement and will also be easily accessible for exchange.

Uppfinningen skall nu beskrivas i anslutning till ett på bifogade ritningsblad visat utföringsexempel. där Pig. 1 schematiskt visar en planvy av ett flexibelt chassi.The invention will now be described in connection with a drawing sheet attached shown embodiment. where Pig. 1 schematically shows a plan view of a flexible chassis.

Pig. 2 visar chassit enligt f ig. 1 med monterade f ramvagnsdetaljer och karossinfästningsdetaljer, och där Pig. 3 schematiskt visar en sidovy av det flexibla chassits inf ástning vid vid en kaross _ I fig. l visas icke vridstyva profiler I och 2 förbundna via rör 4, Den "f räm- re" profilen 2 bestâr av två plattiärn 2a och Zb med mellanliggande distans- er 3. Profilen 2 är "eftergivligt vridf ast" ansluten till rören 4 via expander- bara gummidon 8, vilka bringas att expandera efter införandet i rören 4 genom âtdragning av bultarna 7 som passerar genom distanserna 3.Pig. 2 shows the chassis according to fig. 1 with mounted front carriage details and body attachment details, and there Pig. 3 schematically shows a side view of the mounting of the flexible chassis by a body _ Fig. 1 shows non-torsionally rigid profiles I and 2 connected via pipes 4. the profile 2 consists of two plates 2a and Zb with intermediate spacers The profile 2 is "resiliently rotatable" connected to the pipes 4 via expander only rubber members 8, which are caused to expand after insertion into the tubes 4 by tightening the bolts 7 passing through the spacers 3.

Den andra profilen I är ansluten till rören 4 via styrdon 6. kring vilka rören 4 kan vrida sig. - I f ig. 2 visas, förutom själva chassit, dessutom en del komponenter kopplade till detta. Vid den främre profilen 2 har framvagnsdetaljer 15 och kaross- f ästorgan 14 ritats in. Vid den bakre profilen I har bárorgan 9 f ör kaross- inf ästningen kommit till. Bärorganen 9 innefattar en prof ilbalk ll och elast- iska inf ästningselement 12 och 13. Bärorganen kan lämpligen vara fästa vid profilen l via ett plattiärn _l O. 457 345 s I lig. 3 visas schematiskt hur bárorganet 9 är arrangerat med sina inläst- ningselement 12 och 13 för att passa låarossen A. Med streckade linjer an- tydes även rören 4. vilka kan taga upp de krafter som uppstår när sätet 15 belastas.The second profile I is connected to the pipes 4 via control device 6. around which the pipes 4 can turn. - I f ig. 2 shows, in addition to the chassis itself, also some components connected to this. At the front profile 2, front carriage details 15 and body fastening means 14 drawn in. At the rear profile I, the support means 9 for the body the fortress has come into being. The support members 9 comprise a profile beam 11 and elastic fastening elements 12 and 13. The support members may suitably be attached to the profile l via a plate _l O. 457 345 s I lig. 3 shows diagrammatically how the support member 9 is arranged with its loading elements 12 and 13 to fit the locking rosette A. Dashed lines indicate also means the tubes 4. which can absorb the forces which arise when the seat 15 tax.

Uppf inningen är på intet sätt begränsad till det øvan beskrivna utfórings- exemplet utan modifikationer kan göras inom ramen fór de följande angivna patentkraven.The invention is in no way limited to the embodiment described above. the example without modifications can be made within the scope of the following patent claims.
