[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable connection for connecting a lever portion and the like on a power plant side and an operating portion such as a clutch pedal, and more particularly to a cable connection for dividing and connecting the cable midway. Regarding the device.

[0002]

2. Description of the Related Art Conventionally, a cable for connecting an operating part such as a clutch pedal and an operated part such as a lever part of a power plant is constructed by inserting an inner wire into an outer tube. As described in Japanese Laid-Open Patent Application No. 2-141530, one end of the inner wire is connected to an accelerator pedal that is an operating part, and the other end is connected to a throttle lever on the power plant side. Further, both ends of the outer tube covering the inner wire are connected to a vehicle body, which is a fixing member, via brackets.

Then, the displacement of the accelerator pedal, which is the operating portion, is transmitted to the throttle lever via the inner wire. Further, in order to prevent the vibration generated on the power plant side from being transmitted to the operation part side via the cable, conventionally, it is necessary to prevent the vibration between each end part of the inner wire or outer tube and each mounting part such as the lever part. With a rubber band,
Vibrations generated on the power plant side are also reduced from being transmitted from the power plant via the cable to an operating unit such as a clutch pedal, and further to a driver operating the operating unit or a passenger compartment. Has been done.

[0004]

However, in the above-described cable, due to the frictional relationship between the inner wire and the outer tube, the cable is prevented from being bent when the wiring direction is changed. ,
It is necessary to determine the cable routing route by drawing an arc with a large radius of curvature.

Further, when the radius of curvature is large and the total length of the cable is long, a variation in the direction orthogonal to the axis of the outer tube occurs at the arc portion when the operating portion is operated, so that the cable can be routed freely. There is a problem that the degree is small. Also, since the inner wire is covered with the outer tube, in order to reduce gear noise transmitted through the inner wire, as described above, it is necessary to prevent the both end connecting parts connected to the lever part or the like from being protected. With a rubber band,
There was no choice but to reduce the transmission of vibration to the operation part.

The present invention has been made in view of the above problems, and provides a cable connecting device which improves the degree of freedom of a cable routing path and also reduces the vibration transmitted through the cable. It is intended to be provided.

[0013]

[Function] A cable configured by dividing the cable at a portion where the wiring direction of the cable is desired to be changed,
The cables are connected by the cable connecting device of the present invention. When the inner wire of the connected one cable is displaced in the axial direction by a predetermined length, the inner wire attaching portion to which the one inner wire is attached pivots about the rotation axis by a predetermined angle corresponding to the displacement. In synchronization with this turning, the other inner wire mounting portions also swivel around the rotation axis by the same angle, and the inner wires of the other cables connected to the other inner wire mounting portions are displaced by a predetermined length in the axial direction. To do.

As a result, even if the divided cables are connected by the cable connecting device according to the present invention at the position where the wiring direction is desired to be turned, the same displacement transmission as that constituted by one cable is carried out. Therefore, the performance as a cable is not deteriorated. At this time, in the present invention, since at least one inner wire attachment portion is set apart from the attachment surface, the cable in which the end of the inner wire is attached to the inner wire attachment portion set apart from the attachment surface is The cable can be routed in an aerial position away from the surface, and even if there is an obstacle such as a member protruding on the mounting surface, the cable is routed while avoiding interference with the obstacle.

Further, since the turning radius of the inner wire mounting portion and the mutual angle about the rotation axis between the inner wire mounting portions can be relatively freely selected, the degree of freedom of the cable routing path can be increased. Is greatly improved. In addition, since the cables divided into the appropriate lengths can be connected and routed, the resonance mode of vibration depending on the length of the cable can be adjusted. Further, since the cable connecting device of the present invention can change the routing direction, it is possible to route the cables in a combination of linear paths.

According to the second aspect of the present invention, the inner wire is attached to the arcuate end surface so that the end portion of the inner wire is arranged along the arcuate end surface. Therefore, even if the inner wire is displaced in the axial direction, the displacement of the inner wire in the direction orthogonal to the axis is suppressed, and the contact between the inner wire and the outer tube in each cable is reduced during operation of the inner wire, and the outer tube is included. The radial fluctuation of the cable itself can also be suppressed.

Further, in the invention described in claim 3, the mass body fixed to the swiveling member plays the role of a mass damper, and contributes to the reduction of the vibration input to and transmitted to the inner wire. Further, in the invention described in claim 4, since the turning member is soft-mounted by the vibration isolating rubber, the vibration from the power unit or the like transmitted from the inner wire to the turning member is absorbed by the vibration isolating rubber, and the turning is performed. Transmission to a fixed member such as a vehicle body that supports the member is prevented.

The elastic support structure is constructed, for example, as described in claim 5. In this case, by interposing a collar, the swivel member can be swung around the swivel shaft and is also vibration-proofed by the vibration-proof rubber. Further, in the invention described in claim 6, by connecting the end portion of the outer tube to the cover member via the vibration isolating rubber, the vibration transmitted through the outer tube is transmitted to the vibration isolating rubber. Vibrations absorbed by the outer tube and transmitted
Reduction can be achieved in the middle of the route.

Further, in the invention described in claim 7, since the turning radii of the inner wire attaching portions are different, the displacement amount is different even if the inner wire attaching portions are turned by the same angle. The displacement of one inner wire connected to the other is amplified or reduced and is transmitted to another inner wire connected to the other inner wire mounting portion via the turning member.

Further, in the invention described in claim 8, the shafts of the pair of outer tubes connected to the cover member are orthogonal to each other, and the cover is provided on the extension line of the shaft of the outer tube on the operated portion side of the power plant or the like. Since the center of gravity of the member is arranged and the cover member is elastically supported by the fixed member, differential noise and gear noise generated on the operated side of the power unit are mainly transmitted as vibration in the axial direction of the cable. However, by disposing the center of gravity of the cover member on the extension line of the shaft of the outer tube on the operated portion side as described above, the cover member can be operated by the vibration transmitted from the operated portion. It vibrates as a translational movement of the outer tube on the side in the axial direction.

Therefore, the outer tube on the operating side, which is disposed orthogonally to the outer tube, is transmitted as vibration in a direction orthogonal to the axis through the cover member, but vibration in the direction orthogonal to the axis is transmitted. Is hardly transmitted, so that vibrations such as differential noise and gear noise are prevented from being transmitted to the operating portion side. Further, by elastically supporting the cover member on the fixed member, even if the cover member vibrates as described above, the vibration of the cover member is prevented from being transmitted to the fixed member side.

At this time, as described in claim 6, if each outer tube and the cover member are connected to each other via the cylindrical vibration-proof rubber, in addition to the above-mentioned action, from the operated side. Since the vibration itself transmitted by the cover member is reduced by the anti-vibration rubber, the anti-vibration effect is further improved. Similarly, as described in claim 9, by disposing the center of gravity of the swiveling member on the extension line of the axis of the inner wire on the operated side, by the vibration input via the inner wire on the operated side, With the swivel member, since the inner wire is translated in the axial direction, the vibration is transmitted to the inner wire on the operating side in a direction orthogonal to the axis or in a direction close thereto, so that the transmission of vibration to the operating portion is reduced. To do.

[0023]

An embodiment of the present invention will be described with reference to the drawings.
The cable is formed by inserting an inner wire formed by twisting or braiding a large number of stainless thin wires into an outer tube made of synthetic resin, and has a predetermined flexibility.

In such a cable, for example, both ends of the outer tube are fixed to the vehicle body frame, which is a fixing member, via brackets. Further, both ends of the inner wire protruding from the end of the outer tube are arranged such that one end of the inner wire is connected to a clutch pedal which is an operation part and the other end is connected to a transmission side withdrawal lever which is a power unit. Is being searched.

In the embodiment of the present application, the cables to be routed are divided at predetermined intermediate positions, and the divided cables are connected by a cable connecting device to change the cable arrangement direction. As shown in FIG. 1, the main body of the cable connecting device has a fan-shaped turning member 3 having a predetermined thickness.
The turning member 3 is rotatably supported about a rotation axis P orthogonal to a mounting surface 16 which is an upper surface of a fixing member 6 such as a vehicle body, and is rotatably supported by the fixing member 6. It is composed of a shaft support portion 1 and a circular arc portion 2 which is integral with the shaft support portion 1 and extends in a direction orthogonal to the rotation axis P and has a fan shape.

On the arc-shaped end surface 2a of the arc portion 2,
A pair of inner wire attachment parts is provided. The pair of inner wire mounting portions is formed by two guide grooves 17 and 18 formed along the arc with respect to the arc-shaped end surface 2a. The two guide grooves 17 and 18 are provided at a predetermined interval in the vertical direction, which is the direction along the rotation axis P, and one guide groove 17 is provided near the mounting surface 16. However, the other guide groove 18 is set apart from the mounting surface 16.

The divided end portions 9a and 9b of the inner wire 9 are arranged and fixed to the guide grooves 17 and 18, respectively. Further, a shaft hole 1a penetrating in the thickness direction of the swivel member 3 is formed at the position of the rotating shaft P in the shaft supporting portion 1, and the shaft member 1 can be rotated to the fixing member 6 such as the vehicle body through the shaft hole 1a. Supported.

As shown in FIG. 3, the supporting structure is such that a collar 5 is coaxially mounted in the shaft hole 1a via a vibration-proof rubber 4, and a mounting bolt 13 inserted into the collar 5 is attached thereto. The rotary member 3 is rotatably attached to the fixed member 6 such as the vehicle body frame through the rotary member 3 so that the rotary member 3 can be rotated around the rotation axis P along the attachment surface 16. Further, the cover member 7 covers the tip portion of the arc portion 2 (on the side of the arc-shaped end surface 2a) so as to be capable of turning by a predetermined angle. The cover member 7 is configured by forming a notch 7a into which a tip of the arc portion 2 can be inserted along an axis in a tubular body extending along a curve along the arc of the arc portion 2, and Both ends 7b and 7c of the tubular body can be coaxially attached to the ends of the outer tube 8, respectively. At this time, the end portion 7b side on which the end portion of one outer tube 8 is mounted is located at a position separated from the mounting surface 16 in the direction along the rotation axis P in accordance with the height of the guide grooves 17 and 18. It is set.

The cover member 7 is bolted to a fixing member 6 such as a vehicle body frame along its mounting surface 16. Although the cover member 7 is bolted to the fixing member 6, it may of course be elastically supported to prevent vibration transmission to the fixing member 6. Further, as shown in FIG. 3, the both end portions 7b and 7c of the cover member 7 are
The ends of the outer tubes 8 of the divided cables are coaxially fitted to each other via a cylindrical vibration-proof rubber 10 arranged coaxially. As a result, the outer tube 8 is fixed to the cover member.

At this time, the inner wires 9 projecting from the end portions of the outer tubes 8 are inserted into the cover member 7, and the tip portions 9a thereof are arcuate end surfaces of the arcuate portion 2 of the fan-shaped turning member 3. Guide grooves 17, 18 provided in 2a
Each of them is attached along with, and the supporting portion 1 is supported by the fixing member 6 as described above. By doing so, the ends of the inner wires 9 are covered with the cover member 7 in a non-contact state.

With the above configuration, the divided cables are connected to each other by the cable connecting device of this embodiment, and the cable connecting device freely changes the direction of the cable routing path. . Next, the operation of the cable connecting device will be described. With the cable connecting device interposed in the middle of the cable as described above, for example,
When the clutch pedal is operated, as shown in the schematic diagram of FIG. 5, the inner wire 9 on the clutch pedal side is pulled by an amount corresponding to the operation amount and axially displaced by a predetermined amount, and the inner wire 9 is moved in the axial direction. By the displacement of 1, the fan-shaped turning member 3 turns about the turning axis P by a turning angle corresponding to the displacement. By this turning, the inner wire 9 on the side of the withdrawal lever connected to the turning member is pulled, and the inner wire 9 on the side of the withdrawal lever is pulled by the amount corresponding to the turning of the turning member 3, that is, the clutch. It is displaced in the axial direction by the amount corresponding to the pedal operation amount.

Thus, even if the cable connecting device is provided, the cable transmits the displacement of the operating portion as in the conventional case.
Further, in the above embodiment, the pair of guide grooves 17 and 18 which are the inner wire mounting portions are not configured to be swiveled on the same plane, but are made different in the vertical direction to avoid interference with other members. Has been routed to.

That is, the cable on the inner wire 9 side, which is attached to the one guide groove 18, is attached to the attaching surface 16 of the fixing member.
Therefore, even if there is an obstacle 19 such as various members protruding from the mounting surface 16 near the installed cable coupling device, the cable is set above the obstacle 19. Can be installed (see FIG. 2).

In the above embodiment, only the guide groove 18 on the inner wire mounting portion side is separated from the mounting surface 16. However, in order to avoid interference with other members protruding from the mounting surface 16, Both guide grooves 17 and 18 may be set apart from the mounting surface 16. Further, even if the turning radius R of the turning member 3 is reduced or the angle θ between the mounting portions of the inner wires 9 is changed, no problematic interference occurs between the inner wire 9 and the outer tube 8. Therefore, the turning radius R and the angle θ can be freely selected.

For this reason, the place where the routing route was changed by drawing a curve with a large radius of curvature in the past, but by installing the cable connecting device, the radius of curvature can be set freely, for example, the route can be bent. It becomes possible to greatly improve the freedom of installation. In the above embodiment, the cable connecting device is provided only at one location, but a plurality of dividing positions may be selected to provide a plurality of cable connecting devices.
By doing so, the inner wire 9 is substantially divided, and it is also possible to adjust the length of each divided inner wire 9 to a length that does not resonate with the vibration transmitted from the power unit.

Further, conventionally, the vibration isolation for the cable is 1
At both ends of the cable of this book, it is possible to reduce the vibration by using an anti-vibration rubber provided on the inner wire and the outer tube. Met. However, in this embodiment, it is expected that the main body of the cable connecting device functions as a mass damper to reduce the vibration that transmits the inner wire 9 at the midway position.

At this time, as shown in FIG. 5, a mass body 15 having a predetermined mass may be fixed to the fan-shaped turning member 3 to improve the effect of the mass damper. Further, the vibration input to the turning member 3 from the inner wire 9 is transmitted to the shaft hole 1 of the shaft supporting portion 1.
It is absorbed by the anti-vibration rubber 4 interposed in a and is prevented from being transmitted to the fixed member 6 which pivotally supports the turning member 3. Moreover, since the outer tube 8 and the cover member 7 are also connected via the cylindrical vibration-proof rubber 10, the outer tube 8
The vibration transmitted via the vibration damping rubber 10 is also reduced.

Further, in the above embodiment, the pair of inner wire attaching portions are formed on the arc-shaped end faces 2a of the one fan-shaped turning member 3, but the turning member 3 is arranged as shown in FIG. , The rod portion 20, and rod members 20 and 21 that are integrally formed with the rod portion 1 and that extend radially from the rod portion 1 at a predetermined angle θ with each other. Two
Each inner wire 9 may be attached by providing an inner wire attaching portion at the tip end of 1. In the figure, 23
Is a reinforcing member.

At this time, the rods 20 and 21 do not have to extend in a straight line, and may extend in a curved line, and the angle θ between the rods 20 and 21 may be set to 0 ° so that the ends of the inner wires 9 may be extended. The connections may be matched. Further, in the above embodiment, the distances from the rotation axis P to the guide grooves 17, 18 which are the inner wire mounting portions, that is, the turning radii R are made equal, but they are made different as shown in FIGS. 7 and 8. Good. The turning member 3 shown in FIGS. 7 and 8 is provided with two arc-shaped end surfaces 2b and 2c having different distances from the rotation axis P,
A step is formed in the vertical direction by the two end faces 2b and 2c. Then, the arc-shaped end faces 2b, 2
Inner wire mounting portions are respectively formed in c.

For example, if the turning radius on the clamp pedal side is set shorter, the displacement on the withdrawal lever side is set to be relatively large with respect to the displacement of the inner wire 9 on the clamp pedal side. In particular, in recent years, a power assist mechanism has been added to the operation unit side, and optimal tuning of the movement amount (stroke amount) is demanded rather than reduction of the operation force. It is possible to easily tune the stroke amount on the operation unit side to the optimum value while maintaining the same displacement amount as the conventional stroke amount.

In this embodiment, the cover member 7 has only the end portions 9a and 9b in a non-contact state so that the end portions 9a and 9b of the inner wire 9 of each cable do not interfere with other members. Although the cover member 7 has a shape to cover, the cover member 7 may have a shape to cover the entire arc-shaped end surface 2a of the turning member 3. Next, a second embodiment will be described.

In the first embodiment, only the end portions 9a and 9b of the inner wire 9 attached to the tip portion (arc side) of the arc portion 2 of the fan-shaped turning member 3 are covered with the cover member 7 so that they can be turned by a predetermined angle. However, in the second embodiment, as shown in FIG. 9, the fan-shaped turning member 3 is entirely covered. In addition, in FIG. 9, A indicates a position where the turning member 3 is pivotally supported.

The divided outer tubes 8a, 8b
The mounting axes L1 and L2 for the cover member 7 are arranged so as to be orthogonal to each other. In the drawing, the outer tube 8a on the left side is connected to the power plant side which is the operated side, and the outer tube 8b on the lower side is connected to the clutch pedal side on the operating side. At this time, an arc member 2 having a long arc, such as a semicircular shape, is adopted so that the inner wire 9 inserted through the outer tube 8 does not move in the direction orthogonal to the axis when the cable is operated. The attachment point 9 of the inner wire 9 to the arcuate end surface 2a of the arc member 2
a is set to a position that is offset from the end of the end surface 2a by the amount of axial displacement of the inner wire 9.

With this setting, the position where each inner wire 9 separates from the turning member 3 is prevented from coming to the end of the arc-shaped end face 2a, and the fluctuation of the inner wire 9 in the direction orthogonal to the axis due to the operation is reduced. To be done. Further, as shown in FIG. 9, the center of gravity G1 of the cover member 7 is set so as to be located on the extension line of the mounting axis L1 of the outer tube 8a on the power plant side.

Further, the cover member 7 is fixed to the fixing member as shown in FIG.
It is elastically supported at the position of B in. At this time, the rigid resonance with the cover member 7 as the mass body is set sufficiently lower than the frequency at which vibration is desired to be isolated. For example, since differential noise and gear noise cause problems of 400 Hz or higher, the rigid resonance of the cover member is set to 300 Hz or lower.

The other structure is the same as that of the first embodiment. With this setting, the vibration transmitted to the cover member 7 via the outer tube 8a on the power plant side is prevented from being transmitted to the fixed member side such as the vehicle body frame. Further, the diff noise and the gear noise generated on the power plant side are mainly input to the cover member 7 as vibration in the cable axial direction, but in the present embodiment, on the extension line of the mounting axis L1 of the outer tube 8a on the power plant side. To
Since the center of gravity G1 of the cover member 7 is set, the cover member 7 makes a translational movement parallel to the mounting axis L1 of the outer tube 8a on the power plant side by the input vibration.

Therefore, the vibration transmitted to the outer tube 8b on the operating side through the cover member 7 is transmitted as the vibration in the direction orthogonal to the axis L2 of the outer tube 8b. At this time, since the vibration in the direction orthogonal to the axis is hardly transmitted, it is possible to significantly reduce the transmission of the differential noise and the gear noise generated on the power plant side to the vehicle interior without being transmitted to the operating portion. .

Particularly, in recent years, the background noise in the passenger compartment has become low, and the transmission of the above-mentioned differential noise and gear noise to the passenger compartment becomes a problem. In this embodiment, however, the differential noise and gear noise through the cable are caused. Transmission to the vehicle interior can be significantly reduced, and the riding comfort is improved. Other actions and effects are similar to those of the first embodiment.

At this time, as shown in FIG. 10, by adding a predetermined mass body 30 to the swivel member 3, the center of gravity G2 of the swivel member 3 is set to the extending direction of the axis of the inner wire 9a on the operated side. It should be set to the above. With this setting, the vibration transmitted to the swivel member 3 via the inner wire 9a also causes the swivel member 3 to make a translational motion along the extending direction of the axis of the inner wire 9a.
Similarly to the above, by being transmitted to the inner wire 9b on the operating portion side as vibration in the direction orthogonal to the axis, the vibration transmitted to the operating portion side via the inner wire 9 can also be reduced.

[0050]

As described above, by using the cable connecting device of the present invention, it becomes possible to reduce the vibrations transmitted through the cable, especially the inner wire, in the middle of the cable, and the power plant which is the operated portion. Transmission of vibrations such as gear noises and diff noises generated in 1 to the inside of the vehicle through the cable is significantly reduced, and the ride comfort of the vehicle can be improved.

Further, by separating at least one inner wire attachment portion from the attachment surface of the fixing member, the cable side connected to the one inner wire attachment portion can be routed away from the attachment surface, and the attachment surface can be arranged. Even if there are obstacles protruding from the cable, cables can be routed so as not to interfere with the obstacles. Further, by using the cable connecting device of the present invention, the cable can be appropriately divided and installed, the resonance mode of vibration depending on the length of the cable can be adjusted, and the cable can be linearly Since the cables can be installed in combination, the degree of freedom of the cable routing path can be significantly improved.

Further, as described in claim 2, by setting the inner wire attaching portion on an arcuate end face centered on a rotation shaft formed in the turning member, the inner wire can be operated by operating the cable. Fluctuations in the direction perpendicular to the axis can be reduced, friction between the inner wire and the outer tube can be reduced, and whirling of the cable during the operation can be suppressed.

Further, as described in claim 3,
By fixing the mass body to the inner wire mounting part,
The mass damper formed by the inner wire mounting portion and the mass body can be provided in the middle of the inner wire installation, and the vibration transmitted through the inner wire can be reduced. Further, as described in claims 4 and 5, when the turning member is pivotally supported by the fixing member via the vibration isolating rubber, the vibration transmitted to the inner wire attachment portion is transmitted to the vehicle body side via the turning member. It can be prevented from being transmitted.

Further, as described in claim 6,
By connecting the cover member and the outer tube via a tubular vibration-proof rubber, the vibration transmitted to the cover member via the outer tube on the power plant side is reduced, and further the operation is performed via the cover member. Vibration transmitted to the outer tube on the side is reduced. This makes it possible to reduce the vibration transmitted to the operation portion, that is, the vehicle interior side via the outer tube, at the middle position of the outer tube.

Further, as described in claim 7,
By changing the distance from the rotating shaft to the inner wire connection part at the tip of each inner wire attachment part, it is possible to change and set the displacement amount on the operating side and the displacement amount on the operated side, and the stroke amount on the power plant side It is possible to easily tune the stroke amount on the operation unit side to an optimum value while securing the same displacement amount as.

Further, as described in claim 8, the axes of the pair of outer tubes connected to the cover member are orthogonal to each other, and the center of gravity of the cover member is on the extension line of the axis of the outer tube on the operated portion side. And elastically supporting the cover member on the fixing member, it is possible to further reduce vibration transmission through the outer tube and also reduce vibration transmission from the cover member to the fixing member such as the vehicle body frame. It will be possible.

Further, as described in claim 9, by disposing the center of gravity of the turning member on the extension line of the shaft of the inner wire on the operated side, it is possible to further reduce the vibration transmission through the inner wire.
