Definitions
- the invention also refers to co or indicated in its statement, to an improved fork, in terms of its greater stiffness and resistance, which has been specially designed with a view to its integration into universal joints, cardan type or similar and, in particular, in view of its integration into unions of this type that are part of the steering column of motor vehicles, although it could admit other applications in an equivalent manner.
- the aforementioned forks constitute an essential element in the articulation, given that through them the rotational stresses are transmitted between the two segments or sections in which the steering column is divided, where appropriate and given that they must offer a sufficient support for the bearings or bearings on which the pivots are adjusted along the orthogonal axes of the crosshead.
- the forks constituted by a body of a single piece, obtained in a single stamping operation, from an appropriate thickness and quality of metal plate and by means of a progressive tooling or a progressive die-cut matrix, have important technical features and advantages of lightening weight, low cost and ease of manufacture, for the different types of application where they will be used.
- the main advantages that the idea shown in this invention incorporates are based on the increase in stiffness and strength of the assembly, compared to the usual stresses that occur in any cardan joint, also allowing the assembly of all The set is performed optimally.
- This essential feature of the present invention is granted by the aligned circular openings, arranged to receive the corresponding bearings or bearings, which are surrounded by individual flanges or inner necks, since apart from also cooperating in conferring to the assembly the necessary degree of rigidity, they offer a wide bearing support surface, fixing an exact alignment of the bearings, regardless of the thickness of the metal plate from which the assembly is obtained and according to the specific type of application.
- these necks or flanges are obtained by displacement of material, forcing it to flow in a phase of the stamping process although this patent contemplates the formation thereof, both by drawing or extrusion processes as by any Another type of process.
- the aforementioned inner necks of the circular openings may not be completely closed, to facilitate proper mounting of the crosshead and the respective bearings, for which the flow of the material through a given area would be prevented , at a specific stage of the stamping process, avoiding the need for subsequent cutting or machining.
- the indicated one-piece body should only be subjected to a final grinding operation, for the holes or housings that are intended to receive the bearings that ensure the free play of the crosshead, even being able to dispense with this last operation if manages to perform a sufficiently precise stamping, leaving the costs of manufacturing the fork, therefore, reduced to a minimum.
- Figure nQ shows the fork (16) used as an example in various spatial positions, in which the main parts of which it is indicated are indicated with indicative numbers, highlighting the idea set forth herein.
- Figure nQ 2 shows the main views, with the precise sections to obtain an optimal view, also corresponding to the same fork example (16), where the most representative areas of the same are also specifically outlined, in order to clarify to a greater extent the real relative situation of them, with respect to the whole.
- Figure nQ 3 shows a sectional view of the complete assembly of the entire assembly of a joint (20) of any type cardan or similar, where the concept introduced with the present invention is incorporated, so that it is possible to more easily appreciate the advantages of it, that through a Further detailed description may demonstrate the breadth and variety of its possible applications.
- the example in question basically consists of a central body or core (10) base of the fork (16) and specifically prepared to serve as rigid and integral housing of the corresponding end of the tube or bar, not shown in the figures, which would fit into the cavity (21) and pressed by the extensions or folds (10a) of the core (10), next to which it becomes the joint itself and through which it will receive or transmit the rotation efforts that take place during its operation.
- branches (11) or asymmetric wings (13) of the aforementioned fork (16) are also indicated, which are substantially flat and parallel, presenting the circular openings (15) next to their free ends (16) equal and aligned intended to receive the respective bearings or bearings (17) not shown in the figures.
- necks or flanges (14) are obtained within the unique stamping process with which is manufactured the fork (16) in question, through a progressive tooling or a progressive matrix trans ⁇ erizada, for which the displacement of material occurs, forcing it to flow in a defined phase during the progression of the stamping, either by drawing or extrusion processes or by any other type of process.
- the aforementioned inner flanges (14) of the circular openings (15) may not be completely closed, as shown in the example, in order to facilitate assembly suitable of the crosshead and of the respective bearings (19) for which it would be necessary to limit the flow zone of the material, in a specific phase of the stamping process and according to the requirements of the specific application where it is to be used, thus avoiding the need for subsequent cutting or machining,
- the circular openings of the fork branches (11) partially or totally surrounded, as the case may be, by individual flanges (14) or inner necks, arranged to embrace the corresponding bearings or bearings (17) on which the gasket joints are located sealed (18) and the aligned shafts or stumps of the respective crosshead (19) are adjusted, see figure nQ 3.
