Description

Steering column for automobiles

The innovation relates to a steering column for motor vehicles, with the Steering column is connected to a steering wheel.

Usually, a steering wheel is used in steering devices for motor vehicles connected to the steering column by suitable means. Serrations are used between the steering wheel and the steering column; ■ It is also common to connect the steering column and steering wheel by means of Use of securing devices such as screws, etc. to be carried out. Such arrangements are relatively complex and expensive to use.

It is therefore the aim of the innovation, a unit of steering column and To create a steering wheel that is cheaper to manufacture and simpler to assemble.

According to the innovation, the steering wheel has a number of spokes that continue in axial extensions, the axial extensions of the spokes running parallel to the central longitudinal axis of the steering wheel and summarized in a steering tube and permanently connected to this.

According to the innovation, the spokes can form the steering wheel rim Extensions be provided; furthermore, the spokes with the extensions and the axial extensions can have a circular cross-section exhibit.

It is also advantageous if the contact area of the steering tube with the axial extensions has a curvature which corresponds to the radius of the axial extensions.

It is advantageous if the steering tube with the axial extensions in one Shrink connection is connected to each other. Furthermore, the axial extensions among one another and / or the axial extensions be connected to the steering wheel by welding.

The subject of the innovation is shown in an exemplary embodiment.

According to the exemplary embodiment, the steering wheel has four spokes 50. Each spoke 50 is bent so that an extension 52 results which has a circular shape. Furthermore, the spoke is designed in such a way that that the spokes 54 each have an axial extension 56. The appendages 52 together form a closed ring, i.e. the actual ring

Steering wheel, while the spokes 54 extend from this steering wheel rim to the hub. The four axial extensions 56 run in one Section together.

The steering wheel assembly also has a steering tube 22 which has a substantially square cross section. The straight sides of the steering tube 22 are connected by rounded corners, the curvature of which corresponds to the radius of the axial extensions 56. The axial extensions 56 of the spokes 50 are received within the steering tube 22, the steering tube being for example by means of a shrink connection can be connected to the axial extensions 56. It is also a plastic material 60 in the area of the spokes 50 and in the upper Area of the steering tube 22 arranged; this plastic material provides a summary of the parts mentioned.

Between the axial extensions 56 per se and these axial extensions and the steering tube can be welded. One of these welded connections is shown in FIG and denoted by 62.

The subject of the innovation can be used on a truck, for example which has a tiltable cabin. This application example is shown in the figures and is described below.

A steering gear 10 is mounted on the chassis of a truck. A cabin, the bottom plate of which is designated by 14, sits on the Chassis and is arranged there in such a way that it can pivot about an axis 16. A steering wheel 18 is through appropriate devices with a Steering gear 10 connected. In Fig. 1, the elements are shown as they are in the normal position of the car. A handlebar 24 is within the lower end of the steering tube 22 of this

'"" Ford; / GB-222 / January 31, 1978

recorded . A retaining bracket 26, which is attached to the cabin, has a seat 28; In this seat there is a plastic part 30 which serves as a bearing for the steering tube 22. Through this camp there won't be just one Rotation of the steering column also enables the steering column to pivot when the cabin is tilted. On the steering tube 22 is also a Direction snazeiger 32 and a housing 34 for receiving a steering wheel lock 36 are arranged. A cover 38 carried by the support bracket 26, covers the upper part of the arrangement, while the lower part is located within a cover 40 which is attached to the floor panel 14 is arranged.

In the contact area A of the steering tube 22 there is very precise dimensioning made so that the steering tube rod 24 with a there is very little play in the steering tube. This area is also provided with a coating that ensures low friction. However, the contact area B is designed with play. The limitation the area that needs to be machined precisely to the touch sb he cal A contributes to cost reduction.

In FIG. 1, line C denotes the axis of the steering tube rod 24 as well as the steering tube 22 when the cab is tilted; the position of the tip of the Lekrohrstange 24 is indicated by D, while the line E the Limit the movement of these parts in the other direction during the tilting process.

It goes without saying that the arrangement according to the innovation also in other devices than the embodiment can be used. Furthermore, one can be different from the embodiment Number of spokes to be used. It is also possible to modify the steering tube 22 in accordance with the changed number of spokes.

It is also possible to design the steering tube 22 to be circular.
