Definitions

• the present invention relates to a flexible understructure for vehicles, and more precisely to an understructure that in itself does not have to be dimensioned to withstand torsional stresses and in cooperation with e.g. a plastic body or coachwork gives a particularly simple and adequate construction.
• the determining factor to length of time for mobile constructions is how to succed in dimensioning with regard to exhaustion. Materials of high quality and good strength will not be justified if cyclic loads leading to great material strain/concentration of stresses are allowed to appear.
• the main object of the present invention is to provide a flexible understructure for vehicles permitting a particularly simple and adequate construction.
• An other object of the present invention is to provide a flexible understructure beeing easily combined with a plastic body.
• Yet another object of the present invention is to provide a flexible understructure for a vehicle which, in combination with a thin plastic body, in a simple way can carry partial loads acting on the body.
• the understruckture is allowed to twist under influence from movements caused when using the vehicle.
• the understructure can be mounted and dismounted in a convenient way. This conveniency can even be more accentuated when the other attachment between the pipes and the other profile takes place via guiding means of a plastic material, preferably TEFLON ® .
• a plastic material preferably TEFLON ® .
• the batteries By hangning or pushing a battery case onto the two pipes connecting the two torsional week profiles, the batteries, the weight of which can be about half the total weight of the vehicle, will have a favourably low and central position in the vehicle and are in addition easily accessible for exchange.
• Fig. 1 is a schematic plan view of a flexible understructure
• Fig. 2 shows the understructure according to fig.1 with front wheel accessories and means for connecting the body, and where
• Fig. 3 shematically shows a side view of the flexible understructure connected to a body
• FIG. 2 shows, beside the understructure itself, also several components attached to the same.
• front wheel components 15 and body attachment means 14 have been added.
• Att the rear profile 1 carrier means 9 for attaching the body to the understructure have been shown.
• the carrier means 9 include a profil girder 1 1 and elastic attachment means 12 and 13.
• the carrier means are preferably attached to the profile by a flat 10.
• Fig. 3 schematically shows how the carrier means 9 is arranged with its attchment means 12 and 13 to suit the body A. Dotted lines show the pipes 4, being able to pick up the load from the seat 15.
