TECHNICAL FIELD
The present invention relates to a rod coupling mechanism suitable for coupling a rotating rod on one side of the rotating source such as an electric motor in an electrical power guidance apparatus and a rotating rod on an operating side such as a steering rod of a car. TECHNICAL FUNDAMENTALS
An electrical power guidance device, for example, to facilitate the manual orientation of an orientation wheel by adding a torque based on the rotation of a rotating rod of an electric motor output to a torque based on the rotation of the guidance wheel that is operated manually. In such an electrical power guiding apparatus, the guiding rod on the side of the guiding wheel and the rotating rod on the rotating rod side 15 of the electric motor are coupled by means of a rod coupling mechanism (a coupling).
In the case where the guide rod and the rotating rod are coupled by means of the rod coupling mechanism, there is a possibility that an impact at the moment of the reversal of the rotating rod of the electric motor output and the vibration of the motor brushes electric are transmitted to the steering wheel via the rod coupling mechanism and the steering rod, and thereby cause an uncomfortable orientation feeling for the driver. To avoid this, it has been proposed to provide a spacer made of such material as rubber or soft resin for the rod coupling mechanism. However, if the spacer is made softer with an emphasis on reducing impact and vibration, since the soft spacer is likely to undergo creep deformation, kickback can occur in the stem coupling mechanism due to the permanent deformation of the spacer due to repeated load on the spacer. There is a possibility that this can also make the feeling of driver guidance unpleasant. On the other hand, if the spacer is made hard with an emphasis on durability, the sense of orientation improves contrary to the above since there is no setback. However, the feeling of guidance becomes uncomfortable due to the impact and vibration transmitted to the guidance wheel, as described above.
Consequently, a rod coupling mechanism has also been proposed for an electrical guidance device that comprises a pair of rotating transmission members, an intermediate interposed member that is interposed between that pair of rotating transmission members and is elastically deformable, a coupling base body that is coupled to a rotating rod, and another coupling base body that is coupled to another rotating rod. This proposed rod coupling mechanism is one in which, even if it is used for a long period of time, retraction in the rotating direction is difficult to occur between a rotating rod, for example, a rotating rod coupled to the rotating rod of the outlet electric motor, and another rotating rod, for example, the guidance rod coupled to the guidance wheel, which makes it possible to reduce the transmission to the impact guidance wheel at the time of reversing the electric motor and brush vibration, and which, therefore, it excels in durability and prevents the feeling of guidance from becoming uncomfortable (see Patent Document 4).

Accidentally, with such a proposed rod coupling mechanism, each of the coupling base bodies has a base piece and the projection parts project integrally in an axial direction of an axial surface of that base piece, with the result that there is a possibility that, in the axial relative displacement of a rotating rod in relation to the other rotating rod, the projection parts of each coupling base body are pressed against and brought into contact with the base part of the compatible coupling base body, and then collision noise can occur due to this pressure and contact. In addition, there is a possibility that if such relative axial displacement occurs in the transmission of rotation from one rotating rod to the other rotating rod, friction noise may occur due to pressure and contact. Furthermore, because of the relative axial approach and the displacement of one rotating rod in relation to the other rotating rod cannot be absorbed, there is a possibility that it is impossible to reduce the transmission to the brush vibration guidance wheel which causes axial relative displacement. of a rotating rod in relation to the other rotating rod causing axial compressive elastic deformation in the radial projection parts of the intermediate interposed member. If the axial length of the projection part of each coupling base body is made short in order to avoid such pressure and contact, the contact area in the direction around the geometric axis of the projection part of each coupling base body in relation to the intermediate interposed member it becomes small, in which case each member transmitting rotation can be abnormally deformed and the intermediate interposed member is subjected to excessive elastic compressive deformation, thereby possibly causing deterioration in durability.
The present invention was designed in view of the problems described above, and its objective is to provide a rod coupling mechanism that makes it possible to eliminate the occurrence of collision noise in the axial relative displacement of a rotating rod in relation to the other rotating rod and does not generate unpleasant friction noise when transmitting the rotation from one rotating rod to the other rotating rod, and which makes it possible to attach, as desired, a contact area in the direction around the geometric axis of the projection part of each base body of coupling in relation to each rotation transmitting member or the intermediate interposed member, and to avoid excessive elastic compressive deformation of the interposed intermediate interposed member between the coupling base bodies, and thereby suppresses deterioration in durability.

According to the rod coupling mechanism according to the present invention, at least one of the first base part of the coupling base body and the other rotating rod on its axial surface is in contact with an axial surface of the second part of axial projection, while at least one of the first base part of the other coupling base body and the other rotating rod on its axial surface is in contact with an axial surface of the third axial projection part. In addition, the first axial projection part of the coupling base body extends through and beyond an axial surface of the other rotating transmitting member, and, in its distal end axial surface, it opposes an axial surface of the first base part of the other coupling base body with a gap between them, while the first axial projection part of the other coupling base body extends through and beyond an axial surface of a rotating transmitting member, and, on its axial surface distal end, opposes an axial surface of the first base part of the coupling base body with a gap between them.

In a preferred example, each of the pair of rotating transmission members additionally has a protruding part that is integrally formed on an axial surface of the second base part and discontinuously or continuously surrounds the second axial projection part that protrudes from the through hole.
According to the rod coupling mechanism that has the protruding part described above, even if the second and third axial projection part have passed through large elastic compressive deformation or permanent adjustment, and the appropriate function of the second and third projection part axial has thereby been lost, the function of the second and third axial projection part can be replaced by the protruding part.

In that case, the intermediate interposed member having the third base piece can have in the through holes of the third base piece through which both clamp parts of the coupling means are respectively passed through.
If the intermediate interposed member is positioned in relation to the pair of rotation transmission members by both clamp parts of the coupling means through such through holes, the effect derived from the intermediate interposed member can be obtained uniformly in relation to the relative rotation in both directions of the two rotating rods.
With the rod coupling mechanism according to the present invention, in order to ensure that free movement does not occur in the relative initial rotation of a rotating rod in relation to the other rotating rod, in the relative rotation by a fixed degree or less than both rotating rods, each of the first axial projection parts of the one and the other coupling base bodies on their lateral surfaces in the direction around the geometric axis may be in contact with the lateral surfaces in the direction around the geometric axis of each second piece of radial projection of the intermediate interposed member in opposition to it in the direction around the geometric axis. Meanwhile, each of the first axial projection parts of the one and the other coupling base bodies on their lateral surfaces in the direction around the geometric axis may be in non-contact with, in the relative rotation by a fixed degree or less of both. rotating rods, and can be adapted to be brought in contact with, in relative rotation by more than a fixed angle of both rotating rods, lateral surfaces in the direction around the geometric axis of the first radial projection pieces of the pair of limbs of rotation transmission in opposition to the same in the axial direction.

In relative rotation by a fixed degree or less in the R direction between the swivel rod 2 and the guide rod 4, each of the axial projection parts 13 of the coupling base body 3 on its side surfaces 21 and 22 in the R direction is in contact with the side surfaces 79 and 80 in the R direction of each projection piece 73 of the intermediate interposed member 8, but it is not in contact with the lateral surfaces 41 and 42 as well as 61 and 62 of the radial projection pieces 33 and 53 of the transmitting members of rotation 6 and 7 this opposite to them in the R direction. However, each of the axial projection parts 18 of the coupling base body 5 on its side surfaces 23 and 24 in the R direction is in contact with the side surfaces 79 and 80 in the R direction of each projection piece 73 of the intermediate interposed member 8, but it is not in contact with the lateral surfaces 41 and 42 as well as 61 and 62 of the radial projection pieces 33 and 53 of the rotating transmitting members 6 and 7 being opposite to them in the R direction .
The protruding part 38, which consists of the protrusions 45 that discontinuously surround the axial projection part 76 protrudes from the through hole 39, having a shorter length in direction A (projection quantity) than the projection quantity of the axial projection part 76 from the through hole 39, and forms a gap 95, which is less than the corresponding gap 88, between its end faces 46 in direction A and the surface 12. Similarly, the protruding part 58, which is constituted by the protrusions 65 that discontinuously surround the axial projection piece 78 protrudes from the through hole 59, has a shorter length in direction A (projection quantity) than the projection quantity of the axial projection piece 78 a from through hole 59, and forms a gap 96, which is less than the corresponding gap 84, between its end faces 66 in direction A and the surface 17.
With the electric power guidance device equipped with the rod coupling mechanism 1 described above, to mutually couple the rotating rod 2 and the guidance rod 4, which are two rotating rods, when the guidance wheel is manually operated by the conductor, the guide rod 4 is rotated in the R direction, and the rotation of the guide rod 4 in the R direction is transmitted to a drag link and the like as a reciprocating movement through a transmission mechanism not illustrated as gears, thus conferring, a guiding force for the steering control wheels (wheels). In the manual operation of the guidance wheel by the driver, when the electric motor which is controlled by a detection signal of a torque detector to detect the torque applied to the guidance wheel is operated, the rotating rod 2 is rotated in the R direction. of the coupling base body 3 in the R direction is then transmitted to the axial projection parts 18 of the coupling base body 5 by pressing against the radial projection parts 33 and 53 by the axial projection parts 13 at the base of the surface contact side 21 with side surfaces 41 and 61 or contact of side surfaces 22 with side surfaces 42 and 62 after elastic deformation in the R direction of the radial projection pieces 73 by the axial projection pieces 13. As a result, the torque of the rotating rod 2 in the R direction is added to the torque of the guidance rod 4 in the R direction, thereby assisting the manual operation of the guidance wheel by the driver.
With the rod coupling mechanism 1 that couples the rotating rod 2 and the guide rod 4 as it is arranged between the rotating rod 2 and the guide rod 4 in order to transmit the rotation of the rotating rod 2 in the R direction to the orientation 4 which is the other rotating rod, both in the state in which the guidance wheel is not manually operated by the driver and in the state in which the guidance rod 4 is not rotated in the R direction and in the state in which the guidance wheel is manually operated by the driver and the guide rod 4 is rotated in the R direction, in the case where the relative rotation of the rotating rod 2 in the R direction relative to the guide rod 4 is too small to be within less than that about half a difference between width D2 and width D1, the radial projection parts 73 easily undergo compressive deformation. As a result, the very small relative rotation of the rotating rod 2 in the R direction is barely transmitted to the guidance rod 4. In this way, it is possible to reduce the transmission to the impact guidance wheel at the time of reversing the electric motor and vibration. of the brush through the rod coupling mechanism 1 and the guide rod 4, thus making it possible to prevent the feeling of orientation from becoming uncomfortable. In addition, after compressive deformation of the radial projection parts 73 by more than a fixed degree, contact of the side surfaces 21 with the side surfaces 41 and 61 or contact of the side surfaces 22 with the side surfaces 42 and 62 occurs, making it possible to suppress any additional elastic compressive deformation of the radial projection parts 73. As a result, it is possible to prevent the permanent adjustment of the radial projection parts 73 due to their creep. Therefore, it is possible to maintain mutual contact for extended periods of time between, on the one hand, side surfaces 21 and 22 as well as 23 and 24 and, on the other hand, side surfaces 79 and 80 in the R direction of the axial projection parts 13 and 18 and the radial projection pieces 73, so that the retraction is made difficult between the guide rod 4 and the rotating rod 2 in the R direction.
Furthermore, in cases where the guide rod 4 is rotated in the R direction by the manual operation of the guidance wheel by the driver, followed by the rotation of the rotating rod 2 in the R direction by the operation of the electric motor, with the rotating rod 2 tending to be relatively rotated in the R direction with respect to the guide rod 4 by more than a fixed degree, that is, by more than about half the difference between width D2 and width D1, the transmitting members of rotation 6 and 7 transmit the rotation of the rotating rod 2 in the R direction to the guide rod 4 in response to such relative rotation in the R direction by more than a fixed degree by pressing against the radial projection parts 33 and 53 by the axial projection parts 13 at the base of the contact of the lateral surfaces 21 with the lateral surfaces 41 and 61 or the contact of the lateral surfaces 22 with the lateral surfaces 42 and 62, in order to assist the rotation of the guide rod 4.
According to the rod coupling mechanism 1 described above, each of the rotating rod 2 and the base piece 11 of the coupling base body 3 is in contact with the surface 82 in the A direction of the axial projection piece 76 in each of their surfaces 12 and 81 in direction A which are arranged level with each other. Each of the guide rod 4 and the base piece 16 of the coupling base body 5 is in contact with the surface 86 in the direction A of the axial projection piece 78 on each of its surfaces 17 and 85 in the direction A which are arranged leveled with each other. Each of the axial projection pieces 13 of the coupling base body 3 extends through and beyond the surface 56 of the rotating transmitting member 7, and on its distal end surface 83 in direction A, opposite the surface 17 of the base piece 16 of the coupling base body 5 with the gap 84 between them. Each of the axial projection pieces 18 of the coupling base body 5 extends through and beyond the surface 36 of the rotating transmitting member 6, and on its distal end surface 87 in direction A, opposite the surface 12 of the base piece 11 of the coupling base body 3 with the gap 88 between them. In this way, it is possible to avoid contact between, on the one hand, the distal end surfaces 83 of the axial projection parts 13 of the coupling base body 3 and, on the other hand, the surface 17 of the base piece 16 of the base body of coupling 5 and contact between, on the one hand, the distal end surfaces 87 of the axial projection parts 18 of the coupling base body 5 and, on the other hand, the surface 12 of the base piece 11 of the coupling base body 3. In addition, it is possible to allow the axial projection parts 13 and 18 of the coupling base bodies 3 and 5 to be brought into contact with general surfaces in the R direction of the radial projection parts 33 and 53 of the rotating transmitting members 6 and 7. Additionally, it is possible to eliminate the occurrence of collision noise in the relative displacement in direction A of the rotating rod 2 in relation to the guide rod 4, and the unpleasant friction noise is not generated in the transmission of rotation in the R direction of the rotating rod 2 to rod orientation 4. In addition, it is possible to attach, as desired, the contact area in the R direction of each of the axial projection parts 13 and 18 of the coupling base bodies 3 and 5 in relation to the radial projection parts 33 and 53 of the transmitting members of rotation 6 and 7, and to avoid excessive elastic compressive deformation of the intermediate interposed member 8, thus making it possible to improve durability.
In addition, according to the rod coupling mechanism 1, since the rotating transmitting members 6 and 7, respectively, have protruding parts 38 and 58 that are integrally formed on surfaces 36 and 56 of their base parts 31 and 51 , even if the axial projection parts 76 and 78 have undergone major elastic compressive deformation or permanent adjustment, and the proper function of the axial projection parts 76 and 78 has then been lost, the function of the axial projection parts 76 and 78 may be replaced by the contact of protruding parts 38 and 58 in relation to surfaces 12 and 17.
In addition, according to the rod coupling mechanism 1, the intermediate interposed member 8 interposed between the transmitting members of rotation 6 and 7 in direction A has the radial projection parts 73 which are respectively arranged between the radial projection parts 33 and 53 the transmitting members of rotation 6 and 7 in the direction A, each one having a width D2 greater than the width D1 in the direction R of each of the radial projection pieces 33 and 53, and each radial projection piece 73 of the intermediate interposed member 8 has a stiffness less than the stiffness of each of the radial projection parts 33 and 53 of the rotating transmitting members 6 and 7. Consequently, the transmission of the rotation of the rotating rod 2 in the R direction to the guide rod 4 is effected through the elastic deformation of the radial projection parts 73 of the intermediate interposed member 8, so that the transmission of a very small degree of rotation from the rotating rod 2 in the R direction to the orientation rod 4 po ssa be reduced or prevented by the elastic deformation of the radial projection parts 73 of the intermediate interposed member 8. However, the transmission to the guide rod 4 of a wide degree of relative rotation of the rotating rod 2 in the R direction in relation to the guide rod 4 it can be carried out as it passes the radial projection parts 33 and 53 of the rotating transmitting members 6 and 7 which have greater rigidity than the radial projection parts 73 of the intermediate interposed member 8. In addition, in the relative rotation of the rotating rod 2 by more than a fixed degree in the R direction in relation to the guide rod 4, the wide elastic deformation of the radial projection parts 73 of the intermediate interposed member 8 can be prevented by the radial projection parts 33 and 53 of the rotation transmitting members 6 and 7 that have greater rigidity; in this way, even if a flexible resin material that has a small stiffness is used for the intermediate interposed member 8, the permanent adjustment of the intermediate interposed member 8, due to creep, can be reduced. In addition, since the pair of rotating transmitting members 6 and 7 are coupled together via the coupling means 9, it is possible to improve the assembly efficiency, and the mutual separation of the pair of rotating transmitting members 6 and 7 in the direction Due to the elastic deformation of the intermediate interposed member 8, it can be eliminated, making it possible to suppress the diffusion of the pair of transmitting members of rotation 6 and 7 in direction A by more than a fixed extension. Then, it is possible to reduce the transmission to the impact steering wheel at the moment of reversing the electric motor and the brush vibration and eliminate the kickback between the rotating rod 2 and the steering rod 4 in the R direction, thus making it possible to prevent the sense of orientation becomes uncomfortable and obtaining excellent stability and durability.
In addition, according to the rod coupling mechanism 1, since the intermediate interposed member 8 is positioned in the R direction in relation to the pair of rotating transmitting members 6 and 7 by means of the two claw parts 91 and 92 in the middle of coupling 9 which are passed through the through holes 74, the effect derived from the intermediate interposed member 8 can be uniformly obtained in relation to the relative rotation in the R directions of the rotating rod 2 and the guide rod 4.
Although the rod coupling mechanism 1 in the embodiment described above is comprised of a single intermediate interposed member 8, the rod coupling mechanism 1 can alternatively be comprised of two or more interposed intermediate members 8, and each of the rotation transmitting members 6 and 7 can consist of two or more rotation transmitting members. In addition, the numbers of the axial projection parts 13 and 18 of the coupling base bodies 3 and 5, the radial projection parts 33 and 53 of the rotating transmitting members 6 and 7, the radial projection parts 73 of the intermediate interposed member 8, and the claw parts 91 and 92 of the coupling means 9 are not limited to the aforementioned numbers. The surface 12 of the base piece 11 and the surface 81 of the rotating rod 2 may not be leveled with each other, and the surface 17 of the base piece 16 and the surface 85 of the guide rod 4 may similarly not be leveled with each other.
