DE102012015857A1 - Method for processing carbon-fiber-reinforced polymer and carbon tube material for ultralight-cars, particularly for automotive industry, involves assembling carbon tubes to car-chassis - Google Patents

Abstract

The method involves assembling multiple carbon tubes made from carbon fiber layers impregnated with resin to car-chassis. The carbon tubes are glued together over connecting pieces, particularly sockets, for supporting car-chassis. A base bottom frame is connected with a body frame for fitting with the body surface portions. The carbon-fiber reinforced plastic is provided for the manufacturing of the body portions fixed at body frame.

Description

The patent application is an addition to my patent application Kleinst city car with electric drive and storage space from 22.07.2012

The invention specifies an inventive construction of the conventional steel surpassing materials CFRP (carbon fiber reinforcing plastic / fiber-plastic composite material) and carbon tube material in the automotive industry.

Already known are the DE 10 2010 013 985 A1 2012.03.01 the innovative Mobility GbR / GmbH. This patent application apparently relates to a model study of a miniature city car. For a city passenger car for one person, a lightweight frame construction is claimed, which is obviously made of magnesium and claimed a safety standard for drivers

In general, the use of light metal magnesium for the manufacture of vehicle engines and transmissions is known. In addition, however, this material is only limited for use in vehicle construction. This is a disadvantage of this design, because for the E-car construction, the vehicle weight is an essential factor.

The object of the invention is therefore to eliminate the known disadvantages of the known prior art.

The invention solves this problem by specified obstruction of CFRP and carbon tube material for vehicle chassis and vehicle body.

function example

Overall, the specified build-up of CFRP and carbon tubing for the specific design detail of the vehicle provides all the benefits that are essential to a small electric city car.

Starting with the stable vehicle frame as the central element, Mittel produces carbon tube construction, acts as a solid support for all chassis and drive parts and as the basis for the body structure. To these central elements, a category of shafts, containers and drawers is provided, wherein such elements can be intelligently formed on the central elements or attached via carrier systems in an appropriate manner. In particular, the laying of such storage space on outer surfaces results in an optimally economically exploitable interior for the vehicle pilot / vehicle crew. Despite the most economical handling of all material and space resources used, the safety elements for the occupants are optimally intelligently regulated.

The weight of this construction is in a good overall range. The intelligent and intelligent driver can at times easily equip himself with containers for luggage and / or reserve batteries and release these additional objects and / or containers as needed.
