A steering column for a motor vehicle may include a supporting unit and a displacement unit. The supporting unit may be connectable to a chassis of the motor vehicle, and the displacement unit may be displaceable relative to the supporting unit along a displacement path in a crash event. The steering column may further include an energy absorption element positioned between the supporting unit and the displacement unit. In a crash event, the energy absorption element may absorb energy over the displacement path. In some examples, the energy absorption element includes local laser solidifications that help control an energy absorption level of the energy absorption element.

Steering column for a motor vehicle

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 fiber-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 fibers produced by pultrusion as reinforcing fibers, said fibers being oriented parallel to one another in the direction of the longitudinal axis.

Steering column produced from fibre-composite and on the basis of pultrusion, braiding and/or winding technology

Fiber composite components can be formed by winding fibers along tracks of a winding spool of a winding core. The fibers may either be pre-coated with a curable resin, or the curable resin may be applied to the fibers after the fibers are wound along the tracks of the winding spool of the winding core. The curable resin may also and/or alternatively be applied to a mold that receives the fibers wound about the winding spool. The curable resin may then be cured, after which the winding spool and the winding core may be removed in order to release the fiber composite component. In some cases, the winding spool may be removed from the fiber composite component by moving the winding spool inwardly towards an inside of the winding core.

Component made of a fiber composite material and process for producing same

A steering-column assembly for a motor vehicle may include a steering spindle rotatably mounted in a steering-column tube, which steering-column tube is mounted in a console that connects the steering-column directly or indirectly to a body of the motor vehicle. At least one of the components of the steering-column, such as the console, for example, may include a fiber composite component that can be formed by winding fibers along tracks of a winding spool of a winding core, introducing a curable resin into the fibers or a mold to be used with the wound fibers, curing the wound fibers, and removing the winding spool and the winding core so as to release the fiber composite component. The fiber composite component may then be fitted into the steering column assembly.

Steering columns for a motor vehicle and methods for manufacturing same

The invention relates to a steering column for a motor vehicle, comprising a steering spindle mounted rotatably in a steering spindle bearing unit, and comprising a guide bracket for connecting the steering spindle bearing unit to a body of the motor vehicle, wherein at least one component of the steering column is formed at least in part from a fiber-reinforced composite material, wherein a component has a thin-walled braided core which corresponds to the shape of the subsequent component, is formed from a thermoplastic material, and is braided with a fiber material, wherein the braided core is produced in an injection molding method and contains functional elements molded therein.

Steering column with composite fibre elements produced in a braiding method

The invention relates to a steering column for a motor vehicle comprising a steering spindle, which is mounted rotatably about its axis in a steering spindle bearing unit, a holding part, which is designed to connect the steering spindle bearing unit directly or indirectly to the body of the motor vehicle, wherein at least one of the components of the steering column is at least partially formed from a material that contains reinforcing fibers, wherein the reinforcing fibers are arranged along paths on a wall surface and, by means of multiple holding fibers, which run at an angle that is greater than 0&#xb0; in relation to the paths of the reinforcing fibers and enclose the reinforcing fibers, are fixed on the wall surface.
