Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a change cable assembly structure for an automobile, and more specifically, a change cable assembly structure that can stably connect an automatic transmission and a shift lever in an automobile. Regarding.

[Prior art]

Conventionally, an automatic transmission and a shift lever have been connected via a link mechanism so that there is no play, so that the automatic transmission's gear shifting operation and the operation of various switches are performed accurately in conjunction with the movement of the shift lever. I have to. However, in cases where it is structurally difficult to arrange a link mechanism between the automatic transmission and the shift lever, it is necessary to connect both with a flexible change cable, as described in Japanese Utility Model Application Publication No. 59-172628. Concatenated.

A change cable has an inner cable made of a flexible wire inserted into an outer cable that does not stretch in the longitudinal direction but can be bent to some extent. Then, both ends of this outer cable are fixedly attached to each mounting part, and both ends of the inner cable are connected to the respective movable parts of the automatic transmission and shift lever, and the automatic transmission is activated by pushing and pulling the shift lever. It's starting to work in conjunction with each other. Since such a change cable can be bent and wired as desired, it is often used when the structure between the automatic transmission and the shift lever is complex.

[Problem that the invention attempts to solve]

As mentioned above, since the change cable is often used in a bent state, a slight gap is provided between the outer cable and the inner cable. Therefore, when the change cable is routed in a curved manner, so-called play occurs due to the above-mentioned gap. As a result, for example, when operating the inner cable from the tension direction to the compression direction, only the amount of shift lever operation after pushing the inner cable against the outer cable by the length of play mentioned above is actually applied to the automatic transmission side. This is the manipulated variable transmitted to . Therefore, when assembling the automatic transmission and the shift lever, if this play is not sufficiently taken into consideration, accurate linked operation will not be achieved and malfunctions will occur.
Therefore, when the automatic transmission and shift lever are in each shift position, if they are assembled so that they are connected at the middle position of the inner cable play,
When the shift lever is operated in either direction, the play is set to an equally small amount, so that the operation can be performed reliably and malfunctions can be avoided.

However, in the past, the adjustment during assembly for connecting the shift lever and automatic transmission with a change cable relied on the intuition of the operator's skill, so it was not always stable. It was not always possible to obtain accurate connection status.

The present invention was developed in consideration of the above circumstances, and aims to provide a change cable assembly structure for an automobile that can easily obtain a stable and accurate connection state without requiring the operator's skill. purpose.

[Means for solving problems]

The means of the present invention to achieve the above objectives are as follows:
It connects a shift lever that is swingably supported in the shift direction and an automatic transmission, and consists of a fixed outer cable and an inner cable that slides within the outer cable and is provided with a predetermined amount of play. There is a push-pull type change cable, which includes a joint member that connects one end of the inner cable to the shift lever, a day tent mechanism that stops the shift lever at the shift position of each range, and a stop position by this day tent mechanism. a stopper mechanism that restricts the swinging of the shift lever to a position where the joint member has moved by approximately 1/2 of the play of the inner cable; and a stopper mechanism that urges the inner cable in a compression direction or a tension direction with respect to the joint member. The inner cable is biased by the spring, and when the shift lever is swung by approximately 1/2 of the play in the same direction as the biasing direction of the spring, the inner cable is It is connected to a joint member.

[Effect]

One end of the inner cable, which slides with a predetermined length of play within the fixed outer cable, is temporarily connected to a shift lever supported swingably in the shift direction via a joint member, and the other end is connected and fixed to the automatic transmission. and,
The shift lever is tilted from a stop position by a detent mechanism that stops the shift position of each range with moderation to a position regulated by a stopper mechanism. The shift lever moves by approximately 1/2 of the play of the inner cable that is biased in the compression or tension direction with respect to the joint member, and further rocking of the shift lever is prevented at that position. . Therefore, one end of the inner cable is swung in the same direction as the biasing direction of the spring by a distance of approximately 1/2 of the play of the shift lever, and in this state, one end of the inner cable is attached to the joint member. Once connected and fixed, the assembly of the change cable is completed.

[Effect of idea]

According to the present invention, the shift lever and the automatic transmission are connected by a push-pull change cable, and the joint member is shifted from the stop position by the day tent mechanism to a position where the joint member has moved by a distance of approximately 1/2 of the play of the inner cable. A stopper mechanism is provided to restrict the swinging of the lever, and a spring is provided that biases the inner cable in the compression or tension direction with respect to the joint member, so the inner cable is biased by the spring. and the shift lever has approximately 1/2 of the free play.
The inner cable can be connected to the joint member while being swung in the same direction as the biasing direction of the spring by a distance of . Therefore, the shift lever and the automatic transmission can be connected with the change cable with constant and stable accuracy without requiring any skill in assembling the change cable.

〔Example〕

Hereinafter, the present invention will be described in detail based on examples thereof. In the automobile change cable assembly structure of this embodiment, as shown in FIGS. 1 and 2, a shift lever 1 and an automatic transmission 2 are connected by a change cable 3, and the shift lever 1 is operated to shift. By doing so, the automatic transmission 2 performs a predetermined speed change operation.

The shift lever 1 has a shaft portion 1a at its lower end.
is pivotally supported by a lower bearing portion 5a of a base plate 5 fixed to the vehicle body floor 4 so as to be swingable. A bracket 6 is fixed to the shift lever 1, and on the side surface of the bracket 6,
A joint member 7 is attached. One end portion of the inner cable 3b that slides within the outer cable 3a of the change cable 3 is connected to this joint member 7. The outer cable 3a has one end fixed to the base plate 5, that is, the vehicle floor 4, and the other end fixed to the automatic transmission 2.
The outer cable 3a is fixed to a fitting 8 fixed to the
An inner cable 3b slides inside the inner cable 3b, and a gear change lever 9 of the automatic transmission 2 to which the other end of the inner cable 3b is connected is rotated.

The tip of the inner cable 3b for the shift lever 1 is slidably inserted into the through hole of the joint member 7. The joint member 7
A fixing bolt 10 is provided for temporarily fixing the inner cable 3b, and left and right lock nuts 11 and 12 are screwed onto the inner cable 3b on both sides of the joint member 7, respectively. Furthermore, a cylindrical spacer 13 is interposed between the left lock nut 11 and the joint member 7 on the outer cable 3a side, and a spring is provided between the left lock nut 11 and the end surface of the joint member 7 on the outer periphery of the spacer 13. 14 is compressed, and the inner cable 3 is tightened by tightening the left and right lock nuts 11 and 12.
b is fixed to the joint member 7. The biasing force of the spring 14 acts in the compression direction that causes the inner cable 3b to be recessed into the outer cable 3a, that is, on the automatic transmission 2 side.

A cam plate 16 is provided on the upper surface of the base plate 5 on the side along the swinging direction of the shift lever 1.
has been erected. A plurality of daytent recesses 17 are arranged in parallel on the upper edge of this cam plate 16, while on the upper part of the bracket 6 of the shift lever 1,
A plate spring member 19 having a roller 18 that engages with the recess 17 is attached to the tip thereof, and the engagement of the two constitutes a detent mechanism 20 that stops the shift lever 1 at each shift position with moderation. ing. In the case of Fig. 1, the shift lever 1 is in the P range when it is fully tilted.
As shift lever 1 moves backward from this position,
The shift position is changed in the order of each range R-N-D-2-1, and the roller 18 is sequentially engaged with the detent recess 17 and stopped.

On the other hand, as shown in FIG. 2, the front edge 16a of the cam plate 16 is bent at a right angle toward the front in the figure, and the front edge 6a of the bracket 6 is bent so as to wrap around the front end of the bracket 6. A stopper mechanism 31 is formed which is brought into contact with the shift lever 1 and restricts the stop position of the shift lever 1 in the forward direction. In other words, this stopper mechanism 31 allows the joint member 7 to move from the stop position of the shift lever 1 by the detent mechanism 20 to approximately 1/1 of the play of the inner cable 3b.
The shift lever 1 is provided at a position moved by a distance of 2 to restrict the swinging of the shift lever 1.

Note that a position regulation groove 21 is formed inside the base plate 5, and a pin 22 that engages with the regulation groove 21 is provided on the shift lever 1, and the engagement between the two allows the shift lever to be moved between each operation range. A swing regulation mechanism 23 is configured to regulate the swing of 1. That is, a rod 24 (see FIG. 2) that is movable in the axial direction is provided inside the shift lever 1, and the pin 22 is provided to protrude in a direction perpendicular to the rod 24, and the pin 22 is inserted from the shift lever 1. It protrudes laterally toward the cam plate 16 and engages with the regulation groove 21 . This pin 22 is connected to the regulating groove 2 by a spring 25 compressed at the bottom.
1, while the push button 26 at the upper end of the shift lever 1
It is moved downward by the operation of .

The engagement between the regulation groove 21 and the pin 22 is formed corresponding to the engagement position between the recess 17 of the detent mechanism 20 and the roller 18, and when shifting from the N range to the R range and the P range, When shifting from the range to the R range, and when shifting from the D range to the 2nd range and the 1st range, the shift lever 1 will not swing unless the push button 26 is operated.

Furthermore, if the shift lever 1 is connected to the inner cable 3
The recess 1 of the detent mechanism 20 is swung into the P range by being swung to the most forward position where the
P that engages with the pin 22 so that when the shift lever 1 is stopped due to the engagement between the shift lever 1 and the roller 18, the shift lever 1 can be further moved forward and overstroked.
The width of the range regulating groove 21 is formed to be slightly larger than the diameter of the pin 22.

In the above structure, the assembly work for connecting the joint member 7 of the shift lever 1 and the inner cable 3b of the change cable 3 is performed by fixing both ends of the outer cable 3a to the vehicle body, and fixing the other end of the inner cable 3b to the automatic gear shifter. This is carried out with the gear change lever 9 of the machine 2 being operated in the P range, and the shift lever 1 being operated in the most forward position, the P range. In this situation, as mentioned above,
The end edge 6a of the bracket 6 is brought into contact with the end edge portion 16a which is the stopper mechanism 31. The joint member 7 moves by a distance approximately 1/2 of the play of the inner cable 3b from the position where the shift lever 1 is stopped by the detent mechanism 20. At that point, the forward tilting of the shift lever 1 is restricted by the stopper mechanism 31, and the joint member 7 is connected to the inner cable 3.
It will not move more than approximately 1/2 of the play of b.

On the other hand, the tip of the inner cable 3b is connected to the left lock nut 11, the spacer 13, and the spring 14.
is inserted into the joint member 7 with the
The right lock nut 12 is temporarily held at the most extreme position. By loosening the fixing bolt 10, the inner cable 3b can be moved relative to the joint member 7, and the inner cable 3b is pushed in the compression direction, that is, into the outer cable 3a, by the biasing force of the spring 14. There is a play L in the outer cable 3a. From the above state, the shift lever 1 is swung to an overstroke state as shown in FIG.
Then, as mentioned above, the stopper mechanism 3
1 regulates the edge 6a of the bracket 6,
The joint member 7 is stopped at a position where the spring 14 is compressed by a distance approximately 1/2 of the play L of the inner cable 3b. After that, bolt 1
0 to temporarily fix the inner cable 3b to the joint member 7. Thereafter, the inner cable 3b is fixed to the joint member 7 by tightening the left and right lock nuts 11, 12. In this state, the spacer 13 is pressed against the joint member 7 and the left lock nut 11, and the spring 14 does not expand or contract.

When the inner cable 3b and the joint member 7 are connected as described above, when the shift lever 1 returns from the overstroke state to the rear end position and is stopped in the P range by the detent mechanism 20, the spring 14 The inner cable 3b, which has been pushed into the outer cable 3a by the length of the play L, is moved by approximately 1/2 the length of the play L due to the overstroke of the shift lever 1 and is coupled. With the inner cable 3b being pulled out from the outer cable 3a by approximately 1/2 of this play L, the shift lever 1 is stopped by the detent mechanism 20. Therefore, in the stopped state, there is a play of about L/2 in the compression direction and the tension direction with respect to the swinging of the shift lever 1, and the change cable 3 and the shift lever 1 are connected in an optimal state. It will be in the assembled state.

In the above embodiment, the inner cable 3b is connected to the outer cable 3a by the spring 14.
The shift lever 1 is pushed in to the state where there is the most play inside, and the shift lever 1 is similarly overstroked in the pushing direction to be assembled at approximately the center of the play, but the biasing direction of the spring 14 and the overstroke direction of the shift lever 1 are set in the opposite directions to those in the above embodiments, the inner cable 3b is pulled by the spring so that there is no play in the outer cable 3a, the shift lever 1 is overstroked, and the shift lever 1 is assembled in the same manner approximately at the center of the play. You can do it like this.

FIGS. 3 and 4 show different embodiments of an automobile change cable assembly structure provided with stopper mechanisms 32 and 33. In the former, a chevron-shaped protrusion 16b is provided on the front side of the recess 17 of the cam plate 16 with which the roller 18 engages when the shift lever 1 is positioned in the P range, and the roller 18 is stopped by the protrusion 16b. stopper mechanism 32
is formed. In the latter, a mounting bracket 27 is fixed on the base plate 5, and a screw type stopper 28 whose dimensions can be adjusted is provided on this, and this is brought into contact with the front lower end 6b of the bracket 6 attached to the shift lever 1. This is a stopper mechanism 33. In both cases, similarly to the embodiment described above, the gap is provided to restrict the swinging of the shift lever 1 at a position moved by approximately 1/2 the distance of the play of the inner cable 3b. .
As a result, the same effects as described above can be achieved.
