[First Embodiment]
FIG. 1 is a schematic perspective view of an accelerator wire adjusting mechanism according to a first embodiment of the present invention.

As shown in FIGS. 1 and 2, the accelerator wire adjusting mechanism 1 is swingably provided in the fixed system 3 of the vehicle interior 2 and is connected to the accelerator pedal 4 via the link mechanism 5 and a lever bracket 6 and a lever. A wire locking portion 8 provided on the bracket 6 for locking the accelerator wire 7 is provided.

The passenger compartment 2 is formed in a cab such as a truck. The passenger compartment 2 is partitioned by a cab floor panel 9, a cab front panel 10, a cab rear panel (not shown), and a cab roof panel (not shown). The cab front panel 10 is provided with a fixing bracket 11 for supporting the lever bracket 6. The fixing bracket 11 is formed in a substantially plate shape, and extends rearward and vertically from the cab front panel 10. Further, one end of the outer tube 12 that covers the central portion of the accelerator wire 7 in the longitudinal direction is fixed to the upper portion of the fixing bracket 11, and the accelerator wire 7 extending from one end of the outer tube 12 can be moved in the axial direction. It has been inserted. The other end of the outer tube 12 is fixed to an engine (not shown).

The lever bracket 6 is rotatably provided below the fixed bracket 11 around a rotation center axis x extending in the vehicle width direction. The lever bracket 6 includes a main lever portion 13 that extends upward from the rotation center axis x and inclines backward when the accelerator pedal 4, which will be described later, is not depressed, and a main lever portion 13 that extends forward and inclines downward from the rotation center axis x. A sub-lever portion 14 is provided.

The main lever portion 13 is formed in an L-shaped cross section. Specifically, the main lever portion 13 includes a first surface portion 15 orthogonal to the rotation center axis x and a second surface portion 16 orthogonal to the first surface portion 15. The second surface portion 16 is located on an extension line of the outer tube 12 fixed to the fixing bracket 11. Further, a mounting hole 17 (see FIG. 4) for mounting a wire locking portion 8 described later is formed in the second surface portion 16 so as to penetrate in the thickness direction of the second surface portion 16.

As shown in FIG. 4, the mounting hole 17 is formed so that one side is opened at the side end of the second surface portion 16, and is formed in a shape in which one side of a circle is cut out, that is, a C shape. There is. Further, on the inner peripheral surface of the mounting hole 17 formed on the second surface portion 16, a meshing groove 19 that meshes with the locking groove 18 of the wire locking portion 8 described later is formed. Specifically, the locking groove 18 and the meshing groove 19 are formed in a spiral shape.

As shown in FIGS. 1 and 2, the sub-lever portion 14 regulates the rotation of the lever bracket 6 when the accelerator pedal 4 is depressed.

The link mechanism 5 is fixed to the intermediate lever 20 coaxially with the lever bracket 6 and rotatably provided around the rotation center axis x, and extends rearward, and the rear end is the accelerator. A transmission bar 21 that is slidably engaged with the pedal 4 in the front-rear direction is provided. A spring (not shown) for urging the intermediate lever 20 to the accelerator off side is provided between the fixing bracket 11 and the intermediate lever 20. The intermediate lever 20 is formed separately from the lever bracket 6. When the accelerator pedal 4 is depressed, the intermediate lever 20 rotates counterclockwise in FIG. 2 against the spring force of the spring described above. At this time, the intermediate lever 20 pushes the lever bracket 6 counterclockwise to rotate it. Further, when the amount of depression of the accelerator pedal 4 is reduced, the intermediate lever 20 rotates clockwise in FIG. 2 due to the spring force of the above-mentioned spring. At this time, the lever bracket 6 is pulled by the accelerator wire 7 and rotates clockwise following the intermediate lever 20. The accelerator wire 7 is always pulled toward the engine by a spring provided in the engine (not shown).

As shown in FIGS. 3 and 4, the wire locking portion 8 includes an end holder 22 formed in a hollow rod shape surrounding the accelerator wire 7, a cable end 23 fixed to one end of the accelerator wire 7, and an end holder. A damper 24 interposed between the 22 and the cable end 23 is provided.

The end holder 22 is made of a hard resin and has a C-shaped cross section. The end holder 22 is formed to have an inner diameter sufficiently larger than the outer diameter of the accelerator wire 7 so as not to interfere with the axial movement of the accelerator wire 7 and to be crushed in the radial direction when pinched. As shown in FIG. 5, the end holder 22 can be inserted into the mounting hole 17 from the opening 26 on one side of the mounting hole 17 by being crushed in the radial direction. Further, as shown in FIG. 4, a locking groove 18 extending in the circumferential direction is formed on the outer periphery of the end holder 22. The locking groove 18 is formed in a spiral shape. The end holder 22 is not limited to the one made of resin. The end holder 22 may be made of another material that can be elastically deformed in the radial direction and can be restored to its shape by its own elastic force when inserted into the mounting hole 17.

As shown in FIG. 3, the cable end 23 includes a tubular caulking portion 23a that is crimped and fixed to one end of the accelerator wire 7, and a disc-shaped flange portion 23b that extends radially from the caulking portion 23a. The damper 24 is formed in a tubular shape with a soft resin such as rubber, and one end of the damper 24 comes into contact with the flange portion 23b of the cable end 23. The accelerator wire 7 is inserted into a hole (not shown) formed on the central axis of the damper 24. (Also, the other end of the accelerator wire 7 is connected to an engine (not shown). The end holder 22 may be attached to the accelerator wire 7 in advance before attaching the damper 24 and the cable end 23 to the accelerator wire 7. Further, the end holder 22 may be attached to the accelerator wire 7 after attaching the damper 24 and the cable end 23 to the accelerator wire 7. In this case, as shown in FIG. 5, the accelerator wire 7 is attached to the end holder 22. It is preferable to insert the slit 22a into the center hole 22b.

Next, the operation of this embodiment will be described.

When fastening the accelerator wire 7 to the lever bracket 6, as shown in FIG. 5, the opening port 26 of the end holder 22 is directed in the same direction as the opening port 26 of the mounting hole 17, and the end holder 22 is directed to the opening port of the mounting hole 17. By pressing against 26, the end holder 22 is crushed in the radial direction and inserted into the mounting hole 17. The end holder 22 inserted into the mounting hole 17 returns to its original shape by its own restoring force. As a result, the locking groove 18 of the end holder 22 shown in FIGS. 3 and 4 and the meshing groove 19 of the lever bracket 6 mesh with each other, and the end holder 22 is locked in the axial direction. After that, the end holder 22 is rotated around the central axis to adjust the tension of the accelerator wire 7. For example, when it is desired to increase the tension of the accelerator wire 7, the end holder 22 is rotated so as to be separated from the fixing bracket 11. As a result, the damper 24 and the cable end 23 are pushed by the end holder 22, and the tension of the accelerator wire 7 is increased. Further, when it is desired to reduce the tension of the accelerator wire 7, the accelerator wire 7 is rotated in the opposite direction to the above. Since the accelerator wire 7 can be adjusted in the vehicle interior 2, the accelerator wire 7 can be easily adjusted even in a vehicle in which the engine is hidden under the cab floor panel 9.

In this way, since the wire locking portion 8 is provided so as to be able to adjust the position of the accelerator wire 7 with respect to the lever bracket 6 in the axial direction, the accelerator wire 7 can be adjusted not on the engine side but on the accelerator pedal 4 side. .. Therefore, the accelerator wire 7 can be easily adjusted even in a vehicle in which the work around the engine is complicated. Then, the workability of the accelerator wire adjustment work is improved.

Further, the wire locking portion 8 has a rod-shaped end holder 22 that surrounds the accelerator wire 7, a locking groove 18 extending in the circumferential direction is formed on the outer periphery of the end holder 22, and the lever bracket 6 has a locking groove 18. A mounting hole 17 through which the end holder 22 is inserted is formed, and a meshing groove 19 that meshes with the locking groove 18 is formed on the inner peripheral surface of the mounting hole 17 of the lever bracket 6. Therefore, the accelerator wire adjusting mechanism 1 can be compactly installed on the accelerator pedal 4 side with a simple structure.

Since the locking groove 18 and the meshing groove 19 are formed in a spiral shape, the accelerator wire 7 can be adjusted by a simple operation of rotating the end holder 22.

The mounting hole 17 has an opening 26 on one side, and the end holder 22 is formed to have a C-shaped cross section and is elastically deformable, and passes through the opening 26 when crushed in the radial direction. Is formed like this. Therefore, the end holder 22 can be easily attached to the accelerator wire 7, and the end holder 22 can be easily attached to the attachment hole 17.

[Second Embodiment]
Next, a second embodiment of the present invention will be described in which the locking groove 18 of the end holder 22 and the meshing groove 19 of the lever bracket 6 are modified. FIG. 6 is a perspective explanatory view of the end holder 30 and the lever bracket 6. The same reference numerals are given to the same configurations as described above, and the description thereof will be omitted.

As shown in FIG. 6, the end holder 30 is made of a hard resin and has a C-shaped cross section. Further, a locking groove 31 extending in the circumferential direction is formed on the outer periphery of the end holder 30. The locking grooves 31 are not spiral, but are formed in an annular shape with a part cut out, and are formed at a plurality of equal intervals in the axial direction.

The meshing grooves 32 of the lever bracket 6 are formed in an annular shape with a part cut out so as to mesh with the locking grooves 31, and are formed at a plurality of equal intervals in the axial direction.

When adjusting the tension of the accelerator wire 7, pull the end holder 30 detached from the lever bracket 6 near the mounting hole 17 to adjust the tension of the accelerator wire 7 (see FIG. 5), and adjust the tension. While maintaining, insert the end holder 30 into the mounting hole 17 from the opening 26 and mount it. As a result, the locking groove 31 and the meshing groove 32 mesh with each other, and the end holder 22 is fixed to the lever bracket 6.

In this way, even if the locking grooves 31 and the meshing grooves 32 are formed in an annular shape and at a plurality of equal intervals in the axial direction, the accelerator wire 7 can be adjusted on the accelerator pedal 4 side.

[Third Embodiment]
Next, a third embodiment of the present invention in which the mounting structure of the end holder 30 and the lever bracket 6 of the second embodiment has been changed will be described. FIG. 7 is an explanatory view of the end holder 40 and the lever bracket 6 viewed from diagonally above and rearward. The same reference numerals are given to the same configurations as described above, and the description thereof will be omitted.

As shown in FIGS. 7 and 8, the end holder 40 is formed in a tubular shape. Further, a locking groove 41 extending in the circumferential direction is formed on the outer periphery of the end holder 40. The locking grooves 41 are formed in an annular shape, and are formed at a plurality of equal intervals in the axial direction.

As shown in FIG. 9, the mounting hole 42 is formed in a U shape so that the opening 43 is wide. As a result, the end holder 40 can be inserted into the mounting hole 42 from the opening 43 without being crushed. Further, a meshing groove 32 (see FIG. 6) that meshes with the locking groove 41 is formed on the inner peripheral surface of the mounting hole 42 formed on the second surface portion 16.

Further, as shown in FIGS. 7 and 8, the second surface portion 16 of the lever bracket 6 is provided with a holding member 44 for holding the end holder 40 in the mounting hole 42.

The holding member 44 is composed of a clip and is detachably attached to the second surface portion 16. As shown in FIG. 7, the holding member 44 is formed in a substantially U shape, and sandwiches the second surface portion 16 in the plate thickness direction. Further, as shown in FIG. 8, the holding member 44 is formed with a U-shaped notch 45 for inserting the end holder 40.

When adjusting the tension of the accelerator wire 7, pull the end holder 40 that is detached from the lever bracket 6 near the mounting hole 42 to adjust the tension of the accelerator wire 7, and maintain the tension of the end holder 40. Is inserted into the mounting hole 42 from the opening 43 (see FIG. 9) and mounted. After that, the holding member 44 is attached to the second surface portion 16 so as to close the opening 43. As a result, the end holder 40 is fixed to the lever bracket 6. At this time, it is further preferable that the inner peripheral edge 45a of the holding member 44 is engaged in the locking groove 41 of the end holder 40. The mounting hole 42 is formed in a U shape, and the meshing groove 32 is formed only for half an arc shape. However, the inner peripheral edge 45a of the holding member 44 bites into the locking groove 41 of the end holder 40, so that the end holder 40 is formed. Axial movement can be regulated more tightly. Further, when the axial movement of the end holder 40 is sufficiently restricted only by the engagement between the meshing groove 32 and the locking groove 41, the inner peripheral edge 45a of the holding member 44 may not come into contact with the end holder 40. Good.

The holding member 44 is not limited to the above. For example, as shown in FIG. 10, the holding member 46 may be rotatably provided on the second surface portion 16 so as to open and close the opening 43. In this case, as shown in FIG. 11, it is preferable to provide a lock mechanism 47 that regulates the rotation of the holding member 46 that closes the opening 43. For example, the lock mechanism 47 may include claws 48, 49 provided on the holding member 46 and the second surface portion 16 and hooking each other when the holding member 46 is in the closed state, or may have another structure.

The configurations of each of the above embodiments can be combined partially or wholly, unless otherwise inconsistent. The embodiment of the present invention is not limited to the above-described embodiment, and all modifications, applications, and equivalents included in the idea of the present invention defined by the scope of claims are included in the present invention. Therefore, the present invention should not be construed in a limited manner and can be applied to any other technique belonging to the scope of the idea of the present invention.
