Abstract

Appropriate elements shaped like a U-bolt and pre-assembled on the crown of the armature to be determined, house spokes with a circular section and departing with welding constraint from the central hub, to then insert themselves in the external and opposite end, in the tubular appendix of the U-bolt itself, locking in seaming by pressing relevant and monolithic fins still turned up by the jumper, as well as safely by two opposite points of simple welding, moreover in said pressing, the original circular section of the crown undergoes a shaping, whose internal appendage obtained, is suitable for counteract any rotational mobility of the synthetic foam of the steering wheel cover.

Description

Description of the PATENT for INDUSTRIAL INVENTION entitled:

"Specific technological assembly of the vehicle steering wheel armor".

The present invention relates to concrete technical constructive and functional improvements made to the internal metal armature of the steering wheel for automotive and vehicular driving in general.

The traditional technique involved the known bends generally carried out according to a flat profile, rolling or turning over the peripheral crown of the reinforcement ", as well as binding therein by means of the laborious welding process of the" report type, that is, with specific and detailed intrinsic control. , from which, however, the said process does not primarily guarantee the valid and optimal safety performance of the important accessory.

According to the essential purpose of this invention, said factors are positively guaranteed and increased, also in compliance with the International Road Safety Code as well as in the encounter of a significant reduction in the radio mass of the components, together with the remarkable greater sealing or absorption of the loads of the mechanical stresses originated.

To achieve all these purposes and advantages together with the others that will appear in the course of the detailed description that follows, a specific technological process of assembly is carried out, to obtain the internal armature of the vehicle steering wheel of the type miscellaneous whose fundamental characteristic lies in the fact that upon the pre-assembly of specific elements shaped like a flanged tubular U-bolt, suitable to respectively support the external end of each low individual, extending with a simple welding constraint from the control unit moved on the peripheral crown, it then yields for the latter to the uniform continuous circular profile Ra, by butt welding the adjacent ends *, to then implement the stable and immovable constraint of the aforementioned U-bolts by crimping, with pressing of its monolithic fins on the spoke itself Followed for safety by a simple and mutually opposite points of welding.

3i describes below a practical and preferred solution in question, given by way of example and therefore logically not limiting, with reference to the attached drawings in which:

- FIGURE 1 is the plan view of the skeleton of the automotive steering wheel incorporating the principles of the invention and the,

- FIGURES 2-3 are the respective sections along lines II-II and IXI-III, the latter on an enlarged scale, again in the same FIGURE 1.

Referring to the aforementioned figures and combining the detailed list of components, together with the respective functionality with 1, the U-bolts present, for example four in number, are indicated according to the specific inventive feature, that is, each mounted on the respective external end of the individual four rams present. referred with 1a in turn notoriously departing from the central abutment constituted by the orthogonal plate 2 with inserted tube of the column 3 constrained with angular welding 4 (see FIGURE 1).

Said U-bolts 1 in the opposite end to the moz

or 2 * are inserted in pre-assembly on the crown 5 with originally circular section, for the

which follows its continuous circular conformation

by butt welding indicated with 6 of its matching ends.

With a further new characteristic, each r azza 1a with full circular section, starting with vin

welding collet 7 from the aforementioned central hub 2 in their opposite end 8 are inserted into the predisposed internal tubular seat 9 of the aforementioned U-bolt 1 specifically the latter consisting of two

hemi-shells obtained roughly overhanging and external-

mating in alignment as well as resulting

each one always provided with diametrically opposite two monolithic fins 10 (see FIGURES 2-3) -

At said pre-assembly completed by means of a known pressing operation, the circular section of the

crown 5 is subject to a radially internal recess shaping and referred to with 11 in order to

sultare able to counteract any unwanted rotation on itself of the synthetic foam of the steering wheel cover (not shown) * while the U-bolts 1 are still subjected to a valid constraint on the housed end of the spoke 1a by acting with rewound on itself of the flaps "n 10 which acquires the position in 10a * by integrating for extreme safety with simple two to each other or

solder spots 12-12a. _

From the above it is evident how with simple

and innovative technical profiling devices associated in particular with the presence of the elements a

U-bolt 1 positioned on the crown 5 and housing the external ends of the spokes 1a, all with circular profiling, in addition to eliminating the expensive and complex "report" welding, a

smooth and sturdy inner armor of the steering wheel *,

technologically feasible to further advantage *

with a certain simplified construction and assembly rapidity, as well as with confirmation of the safe and stable immovability and anti-vibration and therefore also antiphonetic properties of the components forming the framework itself.

Without prejudice to the innovative principles, the present embodiment allows various modifications of adaptability * with respect to what is not strictly illustrated above as a result of its advantageous application extension to the various types of vehicular means without for this being outside the scope of this invention as protected by the listed below. claims.

Claims (1)
