Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel control cable operating device. More specifically, the present invention relates to a control cable operating device that can remotely control rotation and axial movement of a shaft via a single push/pull control cable.

The control cable operating device of the present invention is not limited to this, but can be employed in various devices.

Conventionally, a link rod transmission change device has been commonly used to remotely control the transmission of FF vehicles, RR vehicles, etc. In addition, recently, 2
Control cable operating devices that employ a book push/pull control cable (hereinafter simply referred to as a cable) as a means of transmitting operating force are beginning to be used.

Control cable operating devices that employ such two cables usually use one cable for shift operation (shaft axial movement operation) and the other cable for select operation (rotation operation).
Alternatively, the shift operation can be performed by pushing and pulling two cables in the same direction, and the select operation can be performed by pushing one of the two cables and pulling the other. .

In other words, shafts such as transmissions are operated with two degrees of freedom, sliding in the axial direction and rotating around the axis, so to speak, in a two-dimensional manner, so force is applied only in the push and pull directions. It is considered necessary to use at least two cables that can transmit

Therefore, the weight and space of the two cables are required, and complicated installation work such as routing and adjusting the two cables and synchronization between the two cables is required.

Therefore, the inventor of the present invention sought to provide a control cable operating device that can transmit operating force with two degrees of freedom using only one cable in order to further reduce weight, save space, and facilitate installation work. As a result of extensive research, we have discovered that in transmissions, etc., axial movement and rotation operations are performed sequentially, and that in push-pull control cables, the outer casing is also an element that can transmit force in the axial direction. By paying attention to these facts, we have completed the present invention.

That is, the present invention provides a control cable operating device for remotely controlling (a) a select operation for rotating a shaft around its axis and a shaft operation for moving it in the axial direction, a driven side fixing member fixed to the driven side fixing member, a pipe member provided slidably in the axial direction on the driven side fixing member, a driven side rod provided slidably in the pipe member; a link mechanism that is interposed between the driven rod and the shaft and rotates the shaft by axial movement of the driven rod; and a connection that moves the shaft in the axial direction by axial movement of the pipe member. (c) an outer casing having one end fixed to an operating side fixing member fixed to the frame and the other end fixed to the pipe member;
(d) a control cable consisting of an inner cable that is slidably inserted into the outer casing and has one end fixed to the driven rod; (d) a shift lever connected to the other end of the inner cable; (e) an operating section configured to perform a select operation and a shift operation by tilting the shift lever to push and pull the inner cable, or by pushing and pulling and rotating the shift lever; A control cable operating device having a locking means for causing an electrical or mechanical restraining means to act on the driven rod in conjunction with a select operation of a shift lever, thereby restraining the driven rod from moving in the axial direction. The main points are as follows.

Next, the control cable operating device (hereinafter simply referred to as the device) of the present invention will be explained with reference to the drawings.

It is.

As shown in FIGS. 1 and 2, the device of the present invention is composed of an operating section 1, a driven section 2, and a cable 3, and allows the operation of the operating section 1 based on the operator's intention.
The signal is transmitted to the driven part 2 via the cable 3, thereby rotating the select and shift shaft 4 of an automobile transmission, etc. around its axis (select operation) and sliding in the axial direction (shift operation). operation).

The operating section 1 has an operating side fixing member 5 fixed to a frame 100 of an automobile or the like. An operating rod 6 is provided on the fixed member 5 so as to be slidable in the axial direction.

The operating rod 6 is connected to an operating mechanism, such as a shift lever 7 shown in FIGS. 1 and 2, for operating the operating rod 6 in its axial direction. The shift lever 7 is rotatably supported by a frame 100 by a pin 8.

The driven part 2 has a driven side fixing member 9 fixed to the frame. A pipe member 10 is provided on the driven side fixing member 9 so as to be slidable in the axial direction.
A driven rod 11 is inserted into the pipe member 10 so as to be slidable in the axial direction. The pipe member 10 is connected to the shaft 4 by a connecting member 10a or the like.

The driven rod 11 and the shaft 4 have an L-shaped bell crank 12 and an arm portion 13 that projects radially outward from the shaft 4, so that the axial movement of the driven rod 11 causes rotation of the shaft 4. are connected like this. One end 14 of the bell crank 12 is attached to the tip of the driven rod 11 with arrows E and F.
It is connected so as to be rotatable in any direction, and further connected to the bell crank body 15 so as to be freely protrusive and retractable. Therefore, even when the driven rod 11 moves linearly, the bell crank 12 smoothly follows and rotates.

Note that the link mechanism connecting the driven rod 11 and the shaft 4 in the present invention is not limited to that shown in FIG. 1, and a conventionally known operation direction changing mechanism such as a rack-pinion mechanism may be appropriately adopted. sell.

The cable 3 has a flexible inner cable 16 that can transmit operating force in both push and pull directions, and a flexible inner cable 16 that can support the reaction force of the operating force of the inner cable 16, as well as a conventional push-pull control cable. 16 and a flexible outer casing 17 that slidably guides the outer casing 16. One end 18 of the outer casing 17 is fixed to the operation side member 5, and the other end 19 is fixed to the pipe member 10. Both ends of the inner cable 16 are fixed to the operating rod 6 and the driven rod 11, respectively.

Furthermore, the driven side fixing member 9 has a driven side rod 11.
Locking means 2 for locking the axial movement of
0 is set. As the locking means 20,
Known restraining means such as a cam member 32 and a locking projection 33 as shown in FIG. 7, or a stopper for regulating the movement range of the locking projection 33 can be used, and As the control means, a thin pull control cable that directly engages and disengages the cam member or stopper, or an electric drive using a solenoid as a direct drive source can be used. The operation of these locking means is controlled by the shift lever 7.
Conventional means may be used, such as activating the pull control cable in conjunction with the select operation, or detecting the completion of the select operation using a limit switch or the like and energizing the solenoid.

Next, the operation of the apparatus of the present invention constructed as described above will be explained.

First, when the locking means 20 is not in operation, by rotating the shift lever 7 in the directions of arrows A and B, the operating rod 6, inner cable 16 and driven rod 11 are moved in the directions of arrows C and D, respectively. That is, it slides in the axial direction. Accordingly, the bell crank 12 rotates in the directions of arrows E and F, causing the arm portion 13 and shaft 4 to rotate in the directions of arrows G and H. Therefore, a selection operation is performed. In the select operation, depending on the rotational position of the shift lever 7, there are two levels: neutral position (N) and a position tilted toward the arrow A side, and three levels: neutral position (N) and a position tilted toward the arrow A and B sides respectively. Various selection positions can be set, such as a step or five steps including intermediate steps.

Next, the locking means 20 is activated in conjunction with each selection operation, so when the shift lever 7 is further rotated in the directions of arrows A and B with the operating rod 11 locked, the operating rod 6 is moved to the position indicated by the arrow C. , slide in the D direction. Along with this, the inner cable 16
is also pulled out from the outer casing 17 in the direction of arrow C or pushed in in the direction of arrow D. However, since the driven rod 11 is locked,
The length of the inner cable 16 between the operating part 1 and the driven part 2 decreases or increases. Therefore, one end 1
On the contrary, the other end 19 of the outer casing 17, which is fixed to the operating side fixing member 5, moves in the direction of the arrow D or the direction of the arrow C, respectively. As shown in FIG.
9 is pushed in the direction of arrow D, and the inner cable 16
This will be easily understood from the fact that the other end 19 is pulled in the direction of the arrow C when the other end 19 is pushed out and bent as shown by the two-dot chain line K.

When the other end 19 moves in the directions of arrows D and C, the pipe member 10 and the connecting member 10a also move in the same direction, and the shaft 4 is operated in the directions of arrows D and C to perform a shift operation.

As described above, in the device of the present invention, the function of one cable 3 can be switched depending on whether the locking means 20 is activated or deactivated.
Different types of operations, ie, select operations and shift operations, can be performed sequentially.

In the devices shown in FIGS. 1 and 2, the select operation and the shift operation are performed by rotating the shift lever 7 in the same direction, but an operating mechanism 21 as shown in FIGS. 4 and 5 is adopted. In this case, the shift lever 7 can be operated in a conventional shift pattern as shown in FIG. 3, for example.

In Figures 4 and 5, 7 is a shift lever;
The shift lever 7 has a pin 22, a clevis 23, It is supported by a shaft 24 or the like.

A guide plate 25 is provided at the lower end of the shift lever 7.
The guide plate 25 is provided with a guide groove 27 that can be engaged with an engaging protrusion 26 that projects radially outward from the operating rod 6. The guide groove 27 is substantially inclined with respect to the axial direction of the operating rod 6.

When configuring the operating mechanism 21 as described above,
When the shift lever 7 is rotated in the directions of arrows L and M, the guide plate 25 is moved in the directions of arrows P and Q in FIG. move in the direction. Therefore, when the shift lever 7 is rotated in the directions of arrows A and B and in the directions of arrows L and M, the operating rod 6 can be slid in the axial direction thereof.

Therefore, there is a certain relationship between the operation of the locking means 20 and the operating direction of the shift lever 7. For example, the shift lever 7 is locked in the tilted position in the directions of arrows L and M and in the upright position, and is locked in the intermediate position. When a relationship that can be canceled is provided, selection and shift operations can be performed based on the shift pattern shown in FIG. Such a relationship is, for example, shift lever 7.
This can be realized by a control means consisting of a combination of a sensor for detecting the angular position in the directions of arrows L and M and a solenoid actuator constituting the lock means 20, or a combination of a pull control cable and a cam means.

In addition, in Fig. 3, the shift positions (S ₁ ), (S ₂ ), (S ₃ ), (S ₄ ), (S ₅ ) of 5 forward gears, the shift position (R) of 1 reverse gear, and neutral Although a shift pattern for a passenger car or the like indicated by position (N) is shown, the operating mechanism 21 shown in FIGS. 4 and 5 can be applied to more complex or simple shift patterns.

Next, a preferred embodiment of the locking means 20 and the locking control means in the apparatus of the invention will be described with reference to FIGS. 5-8c. The locking and unlocking operations can be performed with a relatively small operating force and amount, and the inner cable 16 of the push/pull control cable can sufficiently transmit the operating force in the torsional direction if it is relatively short. Based on this, the locking means 20 is operated using the twisting operation of the inner cable 16.

In this embodiment, the operating part 1 and the operating mechanism 21 are almost the same as those shown in FIGS. The guide plate 25 is rotatably inserted through the guide groove 27, and a stepped portion 28 is formed in the center of the guide groove 27 of the guide plate 25, as shown in FIG. As the guide groove 27 approaches the center part from one engagement end 29, the step part 28 is shaped like an arrow D.
If it is inclined so that it advances in the direction, it is provided in a direction that advances further in the direction of arrow D from the center. A second engaging end 30 is provided at the other end of the guide groove 27 .

Furthermore, the driven part 2 is also almost the same as that shown in FIG.
0 so as to be slidable and rotatable. Note that the operating rod 11 and the shaft 4 are
When connected in a manner similar to that shown in the figure, the operating rod 11 is connected as shown in FIG.
It is preferable to connect the distal end portion 11a to the other portion 11b so as to be rotatable about the axis and not move in the axial direction.

When the shift pattern is set to five forward speeds and one reverse speed as in the case shown in FIG. 3, the locking means is, for example, the cam groove 31 shown in FIG.
The cam member 32 has a cam member 32 and a locking protrusion 33 that engages with the cam groove 31. The cam member 32 is fixed to the driven side fixing member 9. Locking protrusion 33
protrudes from the driven rod 11. Cam groove 3
1 has a shape like three L-shapes connected in a row, and includes a first lock groove 34 extending substantially perpendicular to the axial direction of the driven rod 11;
A first sliding groove 35 and a second sliding groove extend in opposite directions from both ends of the rod and in the axial direction of the driven rod 11.
A sliding groove 36, a second locking groove 37 extending from the tip of the first sliding groove 35 in a direction opposite to the first locking groove 34, and a second locking groove 37 extending from the tip of the second sliding groove 36. is the third lock groove 38 extending in the opposite direction.
It is composed of.

Note that the cam member 32 and the cam groove 31 are preferably formed into a cylindrical shape to ensure engagement with the locking protrusion 33. Further, even if the driven side rod 11 is provided with the cam member 32 and the driven side fixing member 9 is provided with a locking protrusion, the effect is the same. That is, the cam member 32 and the locking protrusion 33 are connected to the driven rod 11.
This is because the relative positions of the driven side fixing member 9 and the driven side fixing member 9 are restricted. Such a relationship may also apply to the guide plate 25 and the engagement protrusion 26.

Next, the operating state based on the regulation by the engagement of the guide groove 27 and the engagement projection 26 and the cam groove 31 and the locking projection 33, which are constructed as described above, will be explained with reference to FIGS. 8a to 8c. For simplicity, we will explain the case where the shift lever 7 is operated from the shift position (N) to the shift position (S ₂ ) and the shift position (S ₄ ) in FIG. The same applies if the shift pattern is complex or simple.

First, move the shift lever 7 in the direction of arrow B in Figure 1.
That is, when operating toward the shift position (S ₄ ), the guide plate 25 moves in the direction of arrow _D1 , as shown in FIG. 8b. At this time, the 8th c.
As shown in the figure, the locking protrusion 33 engages with the first locking groove 34, and the movement of the driven rod 11 in the axial direction is locked. Therefore, the engaging protrusion moves in the direction of arrow _D1 as shown in FIG. The shaft 4 is shifted in the direction of arrow C.

Next, when moving the shift lever 7 in the direction of arrow L in FIG. 1 or FIG.
5 moves in the direction of arrow _P1 in FIG. 8b. Along with this, the engaging protrusion 26 is also pushed in the direction of arrow _P1 .
In this case, the engagement protrusion 26 reliably engages the guide plate 25 at the step 28. Accordingly, the engaging protrusion 26 is also rotated in the direction of arrow _P1 in FIG.
This rotational operation in the direction of arrow _P1 is transmitted by the inner cable 16 to the first position of the locking protrusion 33 in FIG. 8c.
This causes movement along the locking groove 34. Note that during such operation in the direction of arrow _P1 , the axial movement of the driven rod 11, inner cable 16, and operating rod 6 is locked by the first lock groove 34, so that the engaging protrusion 26 is not guided. Sliding along the groove 27 is restricted.

When the shift lever 7 is further rotated in the direction of arrow L, the guide plate 25 moves in the direction of arrow P. At that time, since the locking projection 33 is in contact with the wall surface of the first sliding groove 35, the engaging projection 26 cannot rotate any further in the direction of arrow P. Therefore, the engaging protrusion 26 moves along the guide groove 27 in the direction of the arrow.
The locking protrusion 33 moves in the _D2 direction until it comes into contact with the engaging end 30 of the guide groove 27, and the locking protrusion 33 also moves in the _D2 direction along the first sliding groove 35.

As a result, the driven rod 11 moves toward the arrow D in FIG.
In order to slide in the direction, the bell crank 12 moves in the direction of arrow F.
The shaft 4 is selectively operated in the direction of arrow G.

In this state, when the shift lever 7 is further rotated in the direction of arrow L, the engagement protrusion 26 is rotated in the direction of arrow _P3 , and the locking protrusion 33 is inserted into the second lock groove 37, returning to the locked state. Become.

In this state, when the shift lever 7 is rotated in the direction of arrow B in FIG. 1, the engagement projection 26 is pushed in the direction of arrow _D3 , and the shaft 4 is shifted in the direction of arrow C via the outer casing 17 etc. . The shift operation to the shift position (S ₂ ) is thus completed. The shift lever 7 is preferably guided by a guide (39 in FIG. 1 or 5) according to the shift pattern.

In the embodiment of the device according to the invention shown in FIGS. 6-8c, the locking operation is carried out via a twisting operation of the inner cable 16, so that no operating system other than the cable 3 is required, and the entire device is It has an excellent effect of being extremely simple to configure.

In the embodiments described above, a control cable operating device applied to an automobile transmission operating device is shown as a representative example.
The control cable operating device of the present invention is not limited to such uses, but can be widely applied to various types of equipment having shafts that are operated in the axial and rotational directions, such as various industrial machines and vehicles. It is something. In other words, the control cable operating device of the present invention can reduce the weight of such equipment,
It has many remarkable effects, such as saving installation space and reducing the manufacturing cost and assembly cost of the entire device, and its practical value is extremely large.
