[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedal device for an automobile such as an accelerator pedal, a brake pedal, a clutch pedal and the like.

[0002]

2. Description of the Related Art FIGS. 5 and 6 show an example of an accelerator pedal device 20 used conventionally.
In the figure, 21 is an accelerator pedal, 22 is an accelerator pedal arm, and 23 is an accelerator cable. In this device 20, one end of an accelerator cable 23 is connected (rigidly connected) to a cable attachment pin 24 fixed to an accelerator pedal arm 22, and the pedal tread 25 of the accelerator pedal 21 is depressed. Depending on the shaft 2
5, the accelerator pedal 21 and the accelerator pedal arm 22 are rotated in the arrow A direction in FIG. 5, and the accelerator cable 23 is operated in the arrow B direction.

FIG. 7 and FIG. 8 show another conventional accelerator pedal device 27, in which a rubber member 28 is baked between an accelerator pedal arm 22 and a cable mounting pin 24. Is. The other configurations are similar to those described above, and the accelerator cable 23 is operated by stepping on the pedal step surface 25.

On the other hand, conventionally, the accelerator pedal 21 is usually used.
Pedal stopper 2 to prevent the rotation of the
9 is provided on the floor 30 of the automobile as shown in FIG. The pedal stopper 29 is, for example, as clearly shown in FIG. 10, a mounting member 31 erected on a floor 30 of an automobile, a welding nut 32 welded to an upper end of the mounting member 31, and a welding nut 32. The adjusting bolt 34 is screwed in and fixed by an adjusting nut 33. A head portion 34a of the adjusting bolt 34 serves as a stopper portion of the accelerator pedal 21. In FIG. 10, 35 is a pedal plate attached to the lower end of the accelerator pedal 21, and 36 is a pedal pad that covers the pedal plate 35.

[0005]

However, the conventional accelerator pedal devices 20 and 27 as described above have the following problems. That is, in the accelerator pedal device 20 as shown in FIG. 5 and FIG. 6, since the accelerator cable 23 and the accelerator pedal arm 22 are rigidly coupled, the vibration of the accelerator cable 23 is transmitted via the accelerator pedal 21. It may be transmitted to the tread surface 25 and may be transmitted to the driver's foot as an unpleasant vibration.

Further, in the accelerator pedal device 27 as shown in FIGS. 7 and 8, the cable attachment pin 24 to which the accelerator cable 23 is attached is elastically coupled to the accelerator pedal arm 22 via the rubber member 28 made of baked rubber. Therefore, the cable attachment pin 24 is displaced when the accelerator cable 23 is activated, and the angle between the cable attachment pin 24 and the accelerator cable 23 is changed. When such a situation occurs, a bending force is applied to the accelerator cable 23, so that the accelerator cable 23 may be broken.

The present invention has been made in view of the above circumstances, and an object thereof is to suppress the transmission of vibration to the accelerator pedal, to prevent the accelerator cable from being cut due to bending, and to make an adjustment. An object of the present invention is to provide a pedal device in which a stopper position adjusting mechanism of a pedal stopper made of a bolt or the like can be omitted.

[0008]

In order to achieve the above object, the present invention divides a pedal arm for transmitting a treading force applied to a pedal tread into two arm parts, and these two arm parts are mutually separated. While connecting rotatably,
An elastic member is interposed between the two arm parts.

[0009]

[Operation] Relative displacement between the two arm parts that make up the pedal arm is absorbed by the elastic member interposed between them, and as a result, vibration is prevented from being transmitted from the pedal tread to the driver's foot. To be done. Further, even if there are variations in the size and shape of the cables, pedals, etc., this variation can be absorbed by the elastic member, so there is no need to provide a stopper position adjusting mechanism for the pedal stopper.

The accelerator pedal arm 4 is divided into first and second arm parts 6 and 7, and an elastic member such as a rubber member is provided between the first and second arm members 6 and 7. One accelerator pedal arm 4 is configured by combining them with each other with 8 interposed.

As shown in FIG. 3, the first arm component 6 has a flat plate member 9 extending in the vertical direction, and a cable mounting pin 10 is fixedly mounted on the upper end of the plate member 9. At its lower end, a cylindrical support shaft 11 is integrally connected in a penetrating state. Further, a rectangular punching hole 12 is formed at an intermediate portion of the plate member 9. On the other hand, as shown in FIG. 4, the second arm component 7 is formed by connecting the lower end 14a of the bending plate member 14 to the flat plate member 13 extending in the vertical direction by spot welding or the like. , 14 facing each other with the upper portions of 14 facing each other
a and 15b. In addition, the facing piece 15 described above
Apertures 16a and 16b facing each other are formed in the upper portions of a and 15b, respectively. A pair of upper and lower cut-and-raised pieces 1 are formed in the aperture 16a of one opposing piece 15a.
7a and 17b are provided. Furthermore, the facing piece 15
Insertion holes 18 facing each other are provided in the lower portions of a and 15b.

Thus, the support shaft 11 of the first arm component 6
Is rotatably inserted into the pair of insertion holes 18a and 18b of the second arm component 7, and the first
Also, the second arm parts 6 and 7 are assembled so as to be relatively rotatable around the support shaft 11. Then, one elastic member 8 made of a rubber body is arranged so as to penetrate through the punching hole 12 of the first arm component 6, and both ends of this elastic member 8 are inside the openings 16a and 16b of the second arm component 7. Have been laid up.

Further, one end of the accelerator cable 5 is connected to the cable attachment pin 10 on the upper end of the first arm component 6, and the accelerator pedal 3 is inserted into the insertion hole 19 of the flat plate member 13 of the second arm component 7.

Next, the operation of the accelerator pedal device 1 having the above structure will be described. First, when the driver puts his foot on the pedal tread 2 and depresses it, the accelerator pedal 3 and the second arm component 7 of the accelerator pedal arm 4 move in the direction of arrow A in FIG. Is rotated to. At this time, since the first arm part 6 of the accelerator pedal arm 4 is rotatable around the support shaft 11 with respect to the second arm part 7 at the initial stage of stepping on the pedal tread 2, the first arm part 6 is not rotated, and the second arm part 7 is slightly moved relative to the first arm part 6 by the arrow A.
Is relatively rotated in the direction.

When the depression of the pedal tread 2 is deepened, the elastic member 8 is moved together with the second arm component 7 being further rotated in the direction of arrow A. An elastic force acts on the first arm component 6. Therefore, the first arm component 6 is also rotated in the direction of arrow A together with the second arm component 7 around the rotation center shaft 3a, and accordingly, the accelerator cable 5 is moved in the direction of arrow B in FIG. It is operated to perform a predetermined accelerator operation.

According to the accelerator pedal device 1 as described above, the accelerator operation can be performed by depressing the accelerator pedal 3 as in the conventional case. In addition, the elastic member 8 arranged between the first and second arm parts 6 and 7
Since the relative displacement between the arm parts 6 and 7 is absorbed, the vibration transmitted from the accelerator cable 5 can be absorbed by the elastic member 8. Therefore, it is possible to effectively prevent the uncomfortable vibration from being transmitted to the driver's foot placed on the pedal tread 2.

Further, the stopper of the accelerator pedal 3 is
A stopper position adjusting mechanism (for example, an adjusting bolt 34 and a nut 3 as shown in FIG. 10 is taken into consideration in consideration of variations in dimensions and shapes of members such as the accelerator cable 5 and the accelerator pedal 3.
A stopper position adjusting mechanism (2, 33, etc.) is generally provided, but this variation can also be absorbed by the elastic member 8. Therefore, according to this example,
It is not necessary to provide the stopper position adjusting mechanism as described above,
There is an advantage that the structure of the stopper is simple.

The embodiment of the present invention has been described above.
The present invention is not limited to the embodiments described above, and various modifications and changes can be made based on the technical idea of the present invention. For example, the elastic member 8 is not limited to a rubber body, but a coil spring may be installed between the first and second arm parts 6 and 7, and the elastic member 8 needs to be disposed at a position. It can be changed as appropriate. further,
The present invention is applicable not only to the accelerator pedal device 1 but also to a brake pedal device, a clutch pedal device and the like.

[0021]

As described above, according to the present invention, the pedal arm is divided into two arm parts, the arm members are rotatably connected to each other, and the elastic member is interposed between the arm members. Therefore, the rotational displacement between the two divided arm parts is allowed by the elastic member, and as a result, the vibration is absorbed and the vibration is effectively transmitted to the pedal tread. Can be suppressed. Therefore, it is possible to prevent a situation in which an uncomfortable vibration is transmitted to the driver's foot placed on the pedal tread. Moreover, since the rotational displacement between the two arm parts is allowed (absorbed) as described above, it is possible to prevent a large bending force from being applied to the pedal force transmitting cable connected to one arm part, and this cable It can prevent disconnection. further,
The elastic member can absorb variations in size and shape of members such as the cable and the pedal arm, and therefore the stopper position adjusting mechanism of the pedal stopper can be omitted.
