STEERING COLUMN PRODUCED FROM FIBRE-COMPOSITE AND ON THE BASIS OF PULTRUSION, BRAIDING AND/OR WINDING TECHNOLOGY

摘要

The invention relates to a steering column for a motor vehicle comprising a steering shaft which is mounted in a steering shaft mounting unit and is rotatable about a longitudinal axis, and comprising a support unit for connecting the steering shaft mounting unit to the body of the motor vehicle. At least one component of the steering column is composed at least partially of a fibre-reinforced composite material and the component lies in the flux of force between the steering column and the body. The component is provided with at least one pultrusion layer which has multiple fibres produced by pultrusion as reinforcing fibres, said fibres being oriented parallel to one another in the direction of the longitudinal axis.

1. A process for producing a steering column with a steering spindle that is mounted rotatably about its axis in a steering spindle bearing unit and with a supporting unit that is designed to connect the steering spindle bearing unit directly or indirectly to the body of the motor vehicle, at least one of the components of the steering column being formed as a fiber-composite component, comprising the following steps:
pultruding supporting fibers to form a support; forming a shaped piece by braiding and/or winding reinforcing fibers around the support along predetermined paths on the surface of the support; applying a curable resin to the shaped piece; bringing the shaped piece into a mold, curing the resin and forming the fiber composite component; mounting the steering column while incorporating the fiber composite component in the steering column.
