[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for transmitting the operation of a speed change lever to a driven lever of a speed change mechanism by a remote control cable, and more particularly to a structure for connecting a cable end to the driven lever.

[0002]

2. Description of the Related Art For example, in order to perform appropriate shift control in an automatic transmission, control related to the output state of an engine is required.
For this reason, the output control mechanism of the engine and the shift control mechanism of the automatic transmission are mechanically connected by a cable or a link, and both control mechanisms are automatically operated by only one of the control operations. . When two or more control symmetries are mechanically connected as described above, if there is a variation such as a part processing error between the first control symmetry operation amount and the second control symmetry operation amount, On the other hand, there is a problem that the operation amount of one control symmetry is insufficient and the capability of the control mechanism cannot be sufficiently exhibited.

When this point is described with reference to FIG. 3, when the input lever 3 supported on the support shaft 2 is rotated by an actuator (not shown) within the range of the rotation angle α, the cable 6
The driven lever 13 operatively connected to the input lever 3 by means of the
b, the swivel 16 (which may be a pin) connecting the ends of the cable 6 is connected to the driven lever 1.
3 must be moved and adjusted along the long hole 15 in the longitudinal direction. The remote control cable is connected to an outer tube 8 whose both ends are fixed to the structure by fasteners 7 and 7a.
Is movably inserted in the axial direction, and the starting end of the cable 6 is connected to the input lever 3 by a pin 6a. The cable 6 corresponds to the maximum operation amount (rotation angle α) from the initial position where the input lever 3 is brought into contact with the stopper 5 by the force of the spring 4.
When the swivel 16 is in the position shown in the figure when the swivel 16 is pushed by the movement amount S, the driven lever 13 can be turned only to the position shown by the dashed line, and the driven lever 13 cannot be turned from the stop 14a to the stop 14b. .

Therefore, the position of the swivel 16 required for the driven lever 13 to rotate from the stop 14a to the stop 14b is determined by the operation amount S of the cable 6, and the swivel 16
Is adjusted along the long hole 15, but in this case, if the swivel 16 is simply moved along the long hole 15,
Since the length of the cable 6 is insufficient or the slack ΔS occurs, the initial position where the input lever 3 contacts the stopper 5 does not correspond to the initial position where the input lever 3 contacts the stopper 5. The lever 13 is separated from the stopper 14a.

[0005] In other words, in order to make the input lever 3 and the driven lever 13 move in the respective operation ranges, not only the movement of the swivel 16 connected to the end of the cable 6 along the long hole 15 but also the adjustment of the long hole 15 The connection position of the cable 6 with respect to the swivel 16 must be changed in order to eliminate the excess or shortage of the cable length that occurs when the cable 6 moves along. If the structure disclosed in Japanese Utility Model Laid-Open Publication No. Sho 62-153416 is adopted as a means for removing such an excess or shortage of the cable length, the adjustment becomes simple, but the cost increases, which is not preferable.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a driven lever or an input lever with a long hole such that the driven lever rotates within a predetermined operation range with a predetermined amount of movement of a cable. An object of the present invention is to provide a cable end connecting structure having a simple structure, in which the position of the cable end with respect to the cable length can be easily adjusted without causing an excess or shortage of the cable length.

[0007]

In order to achieve the above-mentioned object, the present invention is configured such that one end of an input lever and a driven lever, which are connected to each other by a cable for transmitting a predetermined amount of movement and rotate. The part has an elongated hole extending in a direction perpendicular to the extending direction of the cable at the initial position of the one lever, and the swivel connected to the end of the cable is moved and adjusted along the elongated hole so as to be fixed. It was done.

[0008]

The elongated hole for supporting the swivel of the driven lever (which may be an input lever) does not extend in the longitudinal direction of the driven lever, but is perpendicular to the extending direction of the cable at the initial position or the maximum operating position of the driven lever. A long hole extending in any direction, more preferably an arc-shaped long hole centered on the end of the outer tube where the cable projects in a bendable manner, so that even if the swivel is moved and adjusted, there is no slack or shortage in the cable. It does not occur and adjustment is simple.

[0009]

FIG. 1 is a side view showing a connecting structure of a cable end according to the present invention. A driven lever 13 interlocked with an input lever (not shown) is supported by a structure by a support shaft 12 and is rotatable between a stopper 14a and a stopper 14b. The remote control cable is supported by the structure at the end of the outer tube 8 by a fastener 7a, and the end 6b of the cable 6 extending from the outer tube 8 is connected to a swivel 16
Thus, the driven lever 13 is fixed to the elongated hole 25.

According to the present invention, at the initial position where the driven lever 13 comes into contact with the stopper 14a, the shape of the elongated hole 25 is configured to extend perpendicular to the direction in which the cable 6 extends from the outer tube 8. With this configuration, the swivel 16 is moved along the long hole 25, and the driven lever 13 is moved by the movement amount S given to the cable 6 to the stopper 14a.
When the position of the swivel 16 that rotates from the position to the stopper 14b is found, and the swivel 16 is fixed at that position by a nut or the like, the input lever and the driven lever 13 (not shown) interlock with each other in a required operation range.

When performing the above adjustment, as shown in FIG. 3, the input lever 3 is brought into contact with the stopper 5 in advance.
The driven levers 13 are held in contact with the stoppers 14 a, respectively, and the end 6 b is pulled out and connected to the swivel 16 so that the cable 6 is not slackened. By doing so, even if the swivel 16 is moved along the long hole 25, the cable 6 does not become loose or short. Strictly speaking, an arc having a radius equal to the length of a portion where the cable 6 can freely bend,
In other words, it is preferable to provide the elongated hole 25 so as to extend along the arc 31 centered on the end 8 a of the outer tube 8. However, the elongated hole in the direction perpendicular to the extending direction of the cable 6 may Since it can be absorbed in the gap with the long hole 25, there is no problem in practical use.

The present invention is applicable not only to the case where the input lever and the driven lever are connected by a cable but also to the case where the input lever and the driven lever are connected by a rod or a link. As shown in FIG. 2, a link 26 connecting the input lever 3 and the driven lever 13 has one end connected to the input lever 3 by the pin 6a, and the swivel 16 connected to the other end in the initial position of the driven lever 13. If the movement is adjusted along the arc-shaped long hole 25 centered on the pin 6a, the length of the link 26 does not become too short or too long, and the effective length of the driven lever 13 (the distance between the support shaft 12 and the swivel 16) is increased. ) Changes, and the driven lever 13 is moved from the stop 14a to the stop 14 in accordance with the rotation angle α of the input lever 3.
b.

According to the present invention, since the input lever and the driven lever operate one-to-one, the same operation and effect can be obtained even if the input lever is used as the driven lever and the driven lever is used as the input lever. Can be In other words, it goes without saying that in the above-described embodiment, the input lever may be provided with a long hole.

[0014]

As described above, according to the present invention, the initial position of one of the input lever and the driven lever, which are connected to each other by the cable for transmitting a predetermined amount of movement, and which are turned, is provided. A long hole extending in a direction perpendicular to the extending direction of the cable is provided, and a swivel connected to the end of the cable is moved and adjusted along the long hole to be fixed, for example, an end of a driven lever. Since it is only necessary to specify the shape of the long hole provided in the part, processing is easy, after holding the input lever and the driven lever in the initial position, stretch the cable between them without loosening, and then By adjusting the movement of the swivel connected to the end of the cable along the long hole of the driven lever, it is easy to set the driven lever to rotate within the specified operating range according to the amount of rotation of the input lever in the specified range. it can.
