Definitions
- Transmission devices known as universal joints are known, designed to transmit a rotational movement of two axes arranged in different relative directions in order to allow angular displacement between one axis and the other.
- Such devices are typically used in the automotive field to transmit the rotational movement to the wheels when they are driving and steering at the same time, as well as in the steering columns of automobiles where it is not possible to transmit the movement through a longitudinal shaft. in a single piece, especially due to the particular geometry of the interior of the vehicle where the different mechanical elements involved in the steering assembly must be assembled and function.
- the improved universal joint proposed by the present invention is intended for the transmission of a two-axis rotational movement with the ability to orient in different directions.
- one end of said axes is provided with a first fork that incorporates holes intended to house the ends of the arms of a crosshead.
- Said crosshead joins together said first fork with the ends of a second fork.
- the main feature of the present invention resides in the fact that the second forks of the axles are mechanically connected to each other by means of an axial displacement device.
- This axial displacement device is designed to absorb the effects of an external impact that could lead to interference in the operation of the mechanical system and even to breakages or breakdowns with serious consequences.
- the use of a universal joint such as the one described advantageously avoids the transmission of rack movements to the steering column of the car, thus isolating the column from the steering assembly.
- Another advantage derived from the present invention is that the possibility of varying the spacing of the forks from the axles greatly facilitates their assembly thanks to the clearance established between them, a fact that allows the mechanical assembly to be adapted in a more comfortable way, always guaranteeing a perfect transmission.
- the axial displacement device of the universal joint object of the present invention consists of a first support plate that is formed integral with the second fork of one of the axles.
- the axial displacement device also comprises an intermediate plate that is parallel to said first support plate.
- a second support plate is provided that is parallel to both.
- the first support plate of the axial displacement device is provided with guide and clamping columns. Said columns are formed in solidarity at one of their ends in the first support plate. In turn, these columns are also integral with said second support plate at their opposite ends. -
- Said intermediate plate is provided " with through holes adapted for the passage through said guide and clamping columns.
- Said intermediate plate also incorporates a column integral with it at one end and integral with the other end , to the second fork of the other axle.
- the relative separation between said first support plate and said intermediate plate defines a displacement between the forks of the respective axes which provides the advantages mentioned above.
- the system reacts by compensating it by moving the assembly formed by the column fixed to the intermediate plate with respect to the guide columns and fastening fixed to the two support plates. Therefore, there is a relative movement between the forks of the axles that allows to absorb any movement caused by an external agent to the transmission system itself, with low sliding load and great torsional rigidity.
- the invention also contemplates the possibility of providing a flexible protective element that covers the axial displacement device surrounding it in order to isolate the mechanical elements from dust, dirt and other external agents that may influence the dynamic behavior of the universal joint.
- This protective element may, for example, be a rubber tube that surrounds the device and, in turn, allows the elements to move in a suitable way.
- the axial displacement device of the universal joint object of the present invention is equipped with elastic means that tend to maintain the separation between the forks of the respective axes before an external force, thus allowing the absorption of loads in collapse.
- the first support plate of the displacement device comprises three cylindrical guide and support columns formed integrally therein at one of their ends. Their opposite ends are fixed by threading to said second support plate.
- the guide and support columns can be hollow bars to reduce the weight of the assembly.
- the intermediate plate is provided with friction bushings housed in the aforementioned holes bushings to allow controlled passage through them of the guide and clamping columns and to improve their sliding.
- the through holes in the intermediate plate have a suitable internal surface finish to allow the tight passage of said columns. Thanks to these characteristics, torque transmission is achieved without play and with very low sliding effort.
- the column integral with the intermediate plate is made up of a cylindrical element fixed to it that passes through a hole in said second support plate.
- the first support plate, the intermediate plate or the second support plate may have a quadrilateral or triangular profile with rounded corners, although the possibility of including any suitable profile is also contemplated.
- Figure 1 is a perspective view of a universal joint in accordance with the present invention.
- Figure 2 is an elevation view of the universal joint of Figure 1.
- Figures 3 and 4 are front views of the forks corresponding to the transmission shafts according to the view of the assembly illustrated in Figure 2.
- figure 5 is a plan view of the universal joint of figure 1.
- extension of the first fork corresponding to the driving axle (6) housing the extension of the first fork corresponding to the driving axle;
- the assembly illustrated in the figures is constituted by a first fork (1) adapted to house a first axis, or driving axis, which has not been illustrated in the drawings for reasons of clarity.
- the end of the driving shaft is housed in an extension (2) of said first fork (1) where there is a housing (3) suitably adapted for it.
- first fork (4) that, similarly, houses a second axle, or driven axle, which has not been illustrated in the drawings either for reasons of clarity.
- driven shaft is similarly housed in an extension (5) of the first fork (4) where there is a housing (6) adapted for it.
- the first forks (1, 4) of both axles are equipped with holes (7, 8) where the ends (9, 10) of the arms of respective spreaders (11, 12) that articulately connect the corresponding first forks (1, 4) to each other with the ends of the second forks (13, 14) of the driving axles and conducted, respectively.
- Both second forks (13, 14) are mechanically connected to each other by means of an axial displacement device designated as a whole by (15) in the figures attached hereto.
- Said axial displacement device (15) has the mission of establishing a certain clearance between the separation of the second forks (13, 14) in order to absorb the effects of an external impact that could negatively affect the normal operation of the mechanical system, as well as to facilitate the assembly of the axles thanks to the aforementioned clearance established between them.
- This axial displacement device (15) essentially consists of a first support plate (16) formed integral with the second fork (13) of the driving shaft, an intermediate plate (17) parallel to the first support plate (16) and a second support plate (18) parallel to both.
- the first support plate (16) is provided with three guide and support columns (19, 20, 21) formed integrally by their ends (22, 23, 24) in said first support plate (16). Said guide and clamping columns (19, 20, 21) are also integral with the second support plate (18) at opposite ends (25, 26, 27). The clamping of the ends (25, 26, 27) can be by threading, while the guide and clamping columns (19, 20, 21) can be solid or hollow bars to reduce the weight of the assembly.
- the intermediate plate (17) of the axial displacement device has through holes that allow the passage through the columns of guide and support (19, 20, 21).
- the intermediate plate (17) is provided with a central cylindrical column (28) integral with it at one end (29) and integral, at the other end (30), with the second fork (14) of the driven shaft.
- Said central column (28) passes through a hole that houses a bush (28a) in the second support plate (18) of the displacement device (15).
- the relative separation (s) between the first support plate (16) and the intermediate plate (17) defines the relative displacement between the forks (13, 14) of the respective axes .
- the effective clearance found for a typical automotive steering column application is approximately 34mm.
- this maximum separation can take any value depending on the mechanical requirements of the joint and the application for which it is intended, and can reach values of 100 mm in some cases, or even more.
- a flexible protective element (31) can be provided that covers the axial displacement device (15) surrounding it.
- a rubber tube (31) can be mounted surrounding the support plates (16, 18) and the intermediate plate (17) so that relative movement of the same in a suitable manner is possible.
- the movement of said elements can be controlled by mounting elastic means (32) in the form of a compression spring in order to maintain the separation (s) between the first support plate (16) and the intermediate plate (17) under collapse efforts, absorbing them in an effective way.
- the first support plate (16), the intermediate plate (17) and the second support plate (18) have a triangular vertex profile rounded.
- the mentioned guide and support columns (22, 23, 24) are located.
- a universal joint such as that described allows stresses of external origin to be absorbed to the system, compensating it by displacing the assembly formed by the column (28) with the intermediate plate (17) with respect to the guide and clamping columns (19, 20, 21) and the plates. support (16,18).
- This is due to the fact that, as indicated, the first support plate (16), the clamping columns (19, 20, 21) and the second fork (13) of the driving shaft are integral with each other, while the column central (28) is integral with the intermediate plate (17) and the other second fork (14). Therefore, there is a relative movement between the forks (13, 14) of both axles that advantageously allows to absorb any movement due to external agents to the transmission system.
- the materials of the elements that make up a universal joint perfected in accordance with the present invention, as well as the shapes, dimensions and other accessory elements may be conveniently replaced by others that are technically equivalent, as long as they do not depart from the essential nature of the present invention nor from the inventive concept thereof defined in the claims that are included below. In this sense, the provision of any number of guide and clamping columns suitable for the needs of the joint will be included within the inventive concept of the present invention.
- the profile of the first support plate, the intermediate plate or the second support plate may be any appropriate profile according to the requirements of the assembly.
