    The invention describes a set of eccentrics (1) for the adjustable support of an axis (ED), where each eccentric comprises an orifice (2) of axis located in its central portion configured for the fixation of a bearing (RC) of an axis (ED) and a pair of fixing holes (3) located at their ends for attachment to a support element (CH). In addition, each eccentric (1) has an elongated and essentially flat shape so that it can only be fixed to said support element (CH) according to two possible orientations. The set of eccentrics (1) is also formed by pairs that allow to implement four different combinations of displacement (D) and angle of inclination Θ of the axis (ED).

    Eccentric assembly for adjustable axle support OBJECT OF THE INVENTION
    The present invention pertains in general to mechanical devices for regulating the position of an axis, for example in the field of automotive or machining devices such as machine tools and the like.
    The object of the present invention is a novel set of eccentrics designed in such a way that they allow to regulate with two degrees of freedom the position of an axis in any type of machinery in a fast and safe way.
    BACKGROUND OF THE INVENTION
    There are numerous occasions when it would be useful to be able to modify the position of an axis, fundamentally with regard to its displacement and its angle of inclination within a plane. Fig. 1 shows the three possible cases corresponding respectively to a modification of the inclination angle, a modification of the displacement, and a modification of both parameters. Fig. 1a shows an axis in an initial position (E0) and the same axis in an end position (E1) in which the inclination angle has been modified by a value (0). Fig. 1b shows an axis in an initial position (E0) and the same axis in an end position (E1) in which the offset has changed a value (D). Fig. 1c shows an axis in an initial position (E0) and the same axis in an end position (E1) in which both the displacement of a value (D) and the inclination of a value (0) have been modified. In this context, the angle of inclination of the axis in its final position (E1) is defined taking as reference the inclination of the axis in its initial position (E0), and the displacement of the axis in its final position (E1) is defined as the distance perpendicular to said axis in its final position (E1) from a central point of the axis in its initial position (E0).
    This situation, which can occur in multiple fields of the industry in general, is currently not satisfactorily resolved, since it is usually necessary to perform the complete disassembly of the mechanical system in question and its

    subsequent assembly. This is very expensive in terms of time and labor, and is a major drawback in many situations.
    For example, specifically in the automotive field, the modification of the displacement and the angle of inclination of the steering axle, which is fixed between the upper and lower respectively of the motorcycle seatposts, allows to modify the front geometry of the motorcycle. This has an important impact on the curve control and the stability of the motorcycle, and therefore a competition context is usual to try to modify the displacement and the angle of inclination of the steering axle in order to adapt the characteristics of the motorcycle to Each circuit in question.
    Fig. 2 shows an example of the elements that are currently used for this purpose, and which only allows the position of the steering axle to be modified on a motorcycle. The steering axle (ED) of the motorcycle is normally fixed to the front area of the chassis, next to the upper and lower respectively, through a pair of parts (ES, EI) called commercially eccentric. The eccentrics (ES, EI) have a flat circular shape and are rigidly fixed respectively to the upper and lower front ends of the chassis. At present, as can be seen in Figs. 2b and 2c, each of the eccentrics (ES, EI) is provided with a hole where the upper bearing (RS) and the lower bearing (RI) that support the steering shaft (ED) are respectively housed. The currently existing solutions for the modification of the displacement are based on changing said eccentric (ES, EI) of steering shaft support (ED) for others that provide the desired displacement. In this example, the eccentrics (ES, EI) are designed to provide a displacement (D) of 10 mm from a reference position (0) in which the steering axis (ED) is centered on said eccentrics (ES, EI ) circular.
    However, the eccentrics (ES, EI) currently used have several drawbacks. First, they only allow the displacement to be modified, but not the angle of inclination. In addition, since they are circular eccentrics (ES, EI), each time a change is made it is necessary to ensure the correct alignment of the upper (RS) and lower (RI) bearings, so each change requires a considerable amount of time. Another disadvantage related to the fact that the eccentrics (ES, EI) are

    Circular is the space required for installation, which may be excessive for some applications.
    In short, the problem of how to modify the angle of inclination and the displacement of an axis quickly and easily has not yet been satisfactorily resolved.
    DESCRIPTION OF THE INVENTION
    The present invention solves the above problems thanks to a set of eccentrics with a new and optimized design that allows the modification of both the displacement and the inclination angle of an axis simultaneously or individually. These eccentrics have an elongated shape that allows space savings in the place where they will be located compared to the current circular eccentrics. In addition, the elongated shape prevents them from being fixed in an unwanted orientation by mistake, thus saving the time required to ensure proper alignment of the upper and lower bearings. Additionally, the set of eccentrics of the invention is organized in pairs so that each pair can be installed according to four possible axle configurations, whereby a large number of combinations of displacement and inclination angle of the axis can be covered with a number relatively small of eccentrics. Another advantage of the invention is related to the use of a code of visible marks arranged in each eccentric to allow a quick and error-free installation.
    While the set of eccentrics of the present invention will be described with special emphasis on its use in the automotive field, this system is generally applicable to the modification of the displacement and inclination angle of any axis in any context in which it is necessary. On the other hand, note that in this document the term “eccentric” is used at all times to refer to pieces that are not eccentric in the strict sense of the word. The reason is to adhere to the terminology usually applied to refer to these parts in the automotive field. However, the term "eccentric" could perfectly be replaced by terms such as "piece" or "element" without any loss of information.

    The present invention is directed to a set of eccentrics for the adjustable support of an axis, where each eccentric comprises an axis hole located in its central portion that is configured for fixing a bearing of an axis, and a pair of holes of fixing located at its ends that are configured for fixing to a support element. In the specific case of applying the invention to a motorcycle, the support element would be the motorcycle chassis. Furthermore, the eccentric assembly of the invention has the particularity that each eccentric has an elongated and essentially flat shape such that it can only be fixed to said support element according to two possible orientations. The elongated shape may in principle be any, although preferably it is an elliptical, oval or rectangular shape with rounded ends.
    As mentioned, this configuration saves space in relation to a circular eccentric, since its narrower dimension can be made much shorter than the diameter of the circumference of the eccentrics commonly used. In the automotive field, this makes it possible to narrow the front portion of the chassis of a motorcycle to which the eccentrics are fixed, and therefore also more aerodynamic. In addition, since it is customary for the eccentrics to be installed embedded in a cavity of the chassis, the use of an elongated eccentric prevents orientation errors, since there are only two possible orientations of installation of each eccentric for the same cavity.
    In principle, each eccentric of the eccentric assembly of the present invention can have a bearing of any kind depending on the loads to which it will be subjected. However, according to another preferred embodiment of the invention especially useful for the automotive field, the bearing of all the eccentrics is a radial and axial bearing. In fact, in the eccentrics of the prior art a radial and axial bearing was normally used in the eccentric located at the lower front end of the chassis, since this bearing must bear both axial and radial loads, and a radial bearing was used in the eccentric located at the upper front end, since this bearing only supports radial loads. The eccentric assembly of the present invention is intended for use with radial and axial bearings in all cases because, due to its great versatility, each eccentric can be installed interchangeably at the upper or lower front end of the chassis. For example, radial and axial bearing can

    10
    fifteen
    twenty
    25
    30
    35
    Be a tapered bearing.
    According to another preferred embodiment of the invention, the shaft bore of each eccentric has a lower flange of smaller diameter configured to prevent the bearing from leaving said bore. Furthermore, preferably some eccentrics of the eccentric assembly have an increasing thickness in the direction of inclination of the shaft. The purpose of this increasing thickness is to guarantee the structural integrity of the piece and to meet the requirements of threaded joint.
    According to another preferred embodiment of the invention, the eccentrics are grouped in pairs formed by a first eccentric and a second eccentric, such that, for a certain relative position of the first eccentric with respect to the second eccentric, the first eccentric It has an axis hole whose location and direction is compatible with the location and direction of the axis hole of the second eccentric. In this context, it is understood that the holes of the first and second eccentrics are compatible when their location and direction allow the correct installation of an axis between them. Thus, the first and second eccentrics of each pair can be fixed to the support element according to four possible axle configurations provided that said relative position of the first eccentric is maintained with respect to the second eccentric, each configuration corresponding to a different combination of displacement and angle of inclination. That is, by describing this system from the point of view of, for example, the first eccentric of a certain pair of eccentrics, said first eccentric can be installed in an upper portion of the support element according to a first orientation, in an upper portion of the element of support according to a second orientation, in a lower portion of the support element according to a first orientation, and in a lower portion of the support element according to a second orientation. Since the relative position of the second eccentric with respect to the first must be maintained, the position and orientation of the second eccentric is uniquely fixed for each of the four positions and orientations described of the first eccentric. Each of these four configurations corresponds to a different combination of displacement and inclination angle of the axis.
    Therefore, using only one pair of eccentrics, four different combinations of displacement and axis inclination can be achieved. By
    5

    25
    30
    35
    For example, for a given pair of eccentrics that correspond to absolute values of displacement of 5 mm and inclination angle of 2 °, its four configurations would be: displacement +5 mm and inclination angle + 2 °, displacement -5 mm and angle of inclination -2 °, displacement +5 mm and inclination angle -2 °, displacement -5 mm and inclination angle + 2 °.
    Thanks to this versatility, in a preferred embodiment of the invention the set of eccentrics comprises 15 pairs of eccentrics configured to provide 45 different combinations of displacement and angle of inclination of the axis. Specifically, the set of 15 pairs of eccentrics includes:
    a) 1 pair with 1 position: displacement 0 and inclination angle 0.
    b) 3 pairs with 2 positions: displacement 0 and inclination angle other than 0.
    c) 3 pairs with 2 positions: displacement other than 0 and inclination angle 0.
    d) 8 couples with 4 positions: displacement and inclination angle other than 0.
    Therefore, the total number of different combinations of displacement and angle of inclination is 45. This constitutes a great saving of space in comparison with the previous systems where a pair of eccentrics was necessary for each displacement, and where the angle of inclination had to Modify through other means.
    However, the fact that each pair of eccentrics has four possible configurations necessitates a way of coding or indicating in a clear way what are the values of displacement and angle of inclination that are achieved with each of them. For this, in another preferred embodiment of the invention, the upper face of each eccentric comprises visible marks indicating the displacement and angle of inclination corresponding to the two possible installation orientations of said eccentric in the upper portion of the support element. In this context, "upper face" is understood as the face of the eccentric that is oriented out of the support element when installed in the upper portion thereof. Thus, in the specific case of its application in automotive, visible marks are immediately perceived as soon as the eccentric is arranged in the corresponding cavity of the upper front portion of the chassis for fixing. Therefore, the information on the displacement and inclination angle of each configuration of each pair is encoded in the eccentric that is installed in the
    5
    10
    fifteen
    twenty
    25

    35
    upper front end of the chassis, and depends on the orientation of said eccentric.
    In principle there are different ways of implementing the visible marks so as to provide the necessary information, although in a particularly preferred embodiment of the invention the marks comprise:
    - A first pair of symbols that indicate the sign of the displacement and the angle of inclination in a first orientation of the eccentric.
    - A second pair of symbols that indicate the sign of the displacement and the angle of inclination in a second orientation of the eccentric.
    - A couple of figures that indicate the numerical value of the displacement and the angle of inclination for any of the orientations.
    More preferably, the marks further comprise a symbol indicating whether the eccentric is the first eccentric or the second eccentric of each pair.
    The system of interpretation of the visible marks will become clearer from the following description referring to the attached figures.

    PREFERRED EMBODIMENT OF THE INVENTION
    An example of an eccentric assembly according to the present invention specifically designed to allow the modification of the displacement and the inclination angle of the steering axle of a racing motorcycle is described below. The modification of these parameters has a direct impact on the frontal geometry of the motorcycle, in particular on the launch angle and offset, which allows its characteristics to be adapted to different competition situations. However, as mentioned earlier in this document, the invention is not restricted to the automotive field, and can be used in any context in which it is necessary to modify the displacement and the angle of inclination of an axis.
    Fig. 3 shows a perspective view of an eccentric (1) according to the present invention. It can be seen as it has a symmetrical truncated ellipse shape, that is, it is elliptical in the portions corresponding to the ends and rectangular in the central portion. In the central portion is the shaft bore (2), which is provided with a lower flange (4) designed to retain a tapered bearing (RC) to whose inner race the steering shaft (ED) is fixed. The eccentric (1) also has a pair of fixing holes (3) arranged at its ends, and which are designed to receive fixing elements such as screws or the like for fixing to the corresponding support element (CH), which in This case is the motorcycle chassis.
    Fig. 4 shows a perspective view of the location on a motorcycle of a pair of eccentrics (1) according to the invention. The first eccentric (1A) fixed to an upper front portion of the chassis (CH) is appreciated, while the second eccentric (1B) fixed to a lower front portion of the chassis (CH) is hidden. In Fig. 5 the upper post of the motorcycle has been removed in order to allow a clearer view of the location of the first eccentric (1A) inside the dedicated cavity made in the upper front portion of the chassis (CH ), to which it is fixed by means of screws that pass through the fixing holes (3). You can also see in this figure how the steering axle (ED) of the motorcycle is

    10
    fifteen

    30
    35
    fixed to the pair of eccentrics (1A, 1B) through the tapered bearings (RC) respectively of the first and second eccentrics (1A, 1B).
    Once the physical configuration and location on the motorcycle of the eccentric (1) according to the present invention have been described in detail, it is now explained with reference to Figs. 6-9 what are the four possible configurations of a particular pair of eccentrics (1A, 1B) and how the displacement (D) and the inclination angle (0) are coded for each of the configurations. As mentioned above, the angle of inclination (0) and the displacement (D) are defined as a function of a vertical reference axis (not shown in the figures) that crosses the center of both eccentrics (1A, 1B). More specifically, the angle of inclination (0) is the one formed by the direction axis (ED) relative to said reference axis and while the displacement (D) is the distance perpendicular to the direction axis (ED) from said steering axis (ED) to a central point of the vertical reference axis. However, it is clear that it would be possible to reference both parameters differently without affecting the position of the steering axis (ED) in each of the configurations.
    First configuration (Figs. 6a and 6b)
    The first configuration corresponds to the installation of the first eccentric (1A) in the upper front portion of the chassis (CH) and the second eccentric (1B) in the lower front portion of the chassis (CH).
    Fig. 6a shows a longitudinal section of the steering shaft (ED) fixed to the pair of eccentrics (1A, 1B). The first eccentric (1A) constitutes the upper support of the steering axis (ED), while the second eccentric (1B) constitutes the lower support of the steering axis (ED). It can be seen how the steering axis (ED) has an inclination corresponding to a negative inclination angle (0) of 2 ° (that is, an angle of -2 °) with respect to the vertical reference axis, and which is offset according to a positive displacement (D) of 10 mm (ie, a displacement of +10 mm) with respect to said vertical reference axis.
    Fig. 6b shows the appearance of the upper face of the first eccentric (1A). This face, as shown in Fig. 5, is fully exposed during its
    5
    10
    fifteen
    twenty
    25
    30
    35
    installation so that it is completely visible by the operator who performs it. For this reason, the marks (5) that indicate the displacement (D) and the inclination angle (0) of the steering axis (ED) in each configuration are arranged on this face.
    The symbol (5b4) serves to differentiate the first eccentric (1A) from the second eccentric (1B) of the pair. In this case, the symbol (5b4) is an "A", which indicates that this eccentric (1) is the first eccentric (1A).
    The symbols (5b3) are used to indicate the absolute value of the displacement (D) and the angle of inclination (0) that this pair of eccentrics (1A, 1B) can provide. In this case, the symbol (5b3) indicates “10 mm / 2 ° which means that the absolute value of the displacement (D) is 10 mm and the absolute value of the angle of inclination (0) is 2 °.
    The symbols (5b1) and (5b2) are used to indicate the sign of the displacement (D) and the angle of inclination (0). However, these symbols (5b1, 5b2) are only active, that is, they provide the information described, when the observer sees them on the upper side of the eccentric (1A). That is, when they coincide with the marks (O, A) on the edge of the cavity of the upper portion of the chassis (CH). When the observer sees them on the lower side of the eccentric (1A), as is the case in Fig. 6b, they are inactive. Therefore, in Fig. 6b the symbols (5b1, 5b2) do not provide any information.
    The symbols (5a1) and (5a2) also serve to indicate the sign of the displacement (D) and the angle of inclination (0). Like the symbols (5b1) and (5b2) above, they are only active when observed on the upper side of the eccentric (1A), as is the case in Fig. 6b. More specifically, the symbol (5a1) located on the upper right side indicates the sign of the inclination angle (0), in this case a "-", and the symbol (5a2) located on the upper left side indicates the sign of the displacement (D), in this case a "+". To avoid errors, in the upper area of the edge of the chassis cavity (CH) in which the eccentric is installed, an “O” referring to the displacement (D) has been marked on the upper left side and, in the upper right side, an "A" that refers to the angle of inclination (0). These indications printed on the chassis allow the operator to avoid errors when installing each
    5
    10
    fifteen
    twenty
    25
    30
    35
    eccentric pair (1A, 1B).
    Therefore, when the first eccentric (1A) is located in the upper front portion of the chassis (CH) according to the orientation shown in Fig. 6b, the displacement (D) of the steering axle (ED) is + 10 mm (sign given by the symbol (5a2)) and the angle of inclination (0) of the steering axis (ED) is - 2 ° (sign given by the symbol (5a1)). Note that the position of the second eccentric (1B) in the lower front portion of the chassis (CH), which is hidden in Fig. 4 above, is uniquely determined by the position of the first eccentric (1A), since The relative position of one with respect to the other is fixed.
    Second configuration (Figs. 7a and 7b)
    The second configuration also corresponds to the installation of the first eccentric (1A) in the upper front portion of the chassis (CH) and the second eccentric (1B) in the lower front portion of the chassis (CH), although in this case it is reversed the orientation of both eccentrics. As a consequence of this change in orientation, the sign of the displacement (D) and the inclination angle (0) of the steering axis (ED) changes, as can be clearly seen in Fig. 7a.
    Fig. 7b shows the upper face of the first eccentric (1A). It can be seen how this first eccentric (1A) is inverted in relation to the position it had in Fig. 6b. The interpretation of the marks (5) is therefore the following.
    The absolute value of the displacement (D) and the angle of inclination (0) remains the same, as indicated by the symbol (5b3). Now, the symbols (5a1, 5a2) are now on the lower side of the eccentric (1A) according to the drawing, and therefore become inactive. On the contrary, the symbols (5b1, 5b2) are now on the upper side of the eccentric (1a) according to the drawing, so that they are active. Therefore, the symbol (5b1) on the upper right side of the eccentric (1A) is interpreted as the sign of the inclination angle (0), in this case a “+”, and the symbol (5b2) on the upper left side as the sign of displacement, in this case a "-". The printed indications (O, A) on the edge of the chassis cavity (CH) confirm which of the signs corresponds to the angle of inclination (0) and the displacement (D). Therefore, for the orientation shown in Fig. 7b, the displacement (D) of the steering axis (ED) is
    5
    10
    fifteen
    twenty
    25
    30
    35
    Third configuration (Figs. 8a and 8b)
    The third configuration corresponds to the installation of the second eccentric (1B) in the upper front portion of the chassis (CH) and the first eccentric (1A) in the lower front portion of the chassis (CH). That is, the second eccentric (1B), which in the two previous configurations was installed in the lower front portion of the chassis (CH), and which was therefore hidden, now goes on to be placed in the upper front portion of the chassis (CH) . Since this is the eccentric (1B) most visible by the operator during installation, it is now the marks (5) located on its upper side that indicate the value of the displacement (D) and the angle of inclination (0) of the axis Address (ED). A reference to each symbol of this second eccentric (1B) is not provided so as not to complicate excess notation, the symbols are organized and named in the same manner as in the previous figures.
    As can be seen in Fig. 8b, the symbol (5b4) that indicates the specific eccentric now adopts the value "B", indicating that it is the eccentric (1B). The symbols (5b3) that indicated the value Absolute displacement (D) and the angle of inclination (0) of the steering axis (ED) remain unchanged, since with this pair of eccentrics (1A, 1B), only the values of 10 mm and 2 ° can be adopted respectively.
    However, due to the change in configuration, a change in the possible signs of displacement (D) and the inclination angle (0) encoded by the symbols (5a1, 5a2, 5b1, 5b2) can be seen. In the first two configurations, the sign of displacement (D) was opposite to the sign of the angle of inclination (0), and consequently each of the pairs of marks (5a1, 5a2) and (5b1, 5b2) have opposite signs. In this third configuration, the sign of displacement (D) is the same as the sign of the angle of inclination (0) and therefore both pairs of marks (5a1, 5a2) and (5b1, 5b2) have equal signs. Therefore, looking at the two symbols (5a1, 5a2) located on the upper side of the eccentric (1B) according to the observer, we see that both the displacement (D) and the angle of inclination (0) of the steering axis (ED ) are positive. That is, in the third configuration the displacement (D) of the steering axis (ED) is + 10 mm and the angle of inclination
    Fourth configuration (Figs. 9a and 9b)
    5 The fourth configuration also corresponds to the installation of the second eccentric (1B) at the upper front end of the chassis (CH) and the first eccentric (1A) at the lower front end of the chassis (CH), although in this case it invert the orientation of both eccentrics (1A, 1B). As a consequence of this change in orientation, the sign of the displacement (D) and the inclination angle (0) changes, 10 as shown in Fig. 9a.
    To know the displacement (D) and the angle of inclination (0) in this case, the operator is only fixed on the mark (5b3) to obtain the absolute values of 10 mm and 2 °, and then on the marks (5b1, 5b2) located on the upper side of the eccentric (1B) according to the observer to obtain the sign "-" of the displacement (D) (mark (5b2) located on the upper left side of the eccentric (1B)) and the sign “-“ of the angle of inclination (0) (mark (5b1) located on the upper right side of the eccentric (1B)). Therefore, in the fourth configuration the displacement (D) of the steering axis (ED) is - 10 mm and the inclination angle of the steering axis (ED) is 20 - 2 °.
