Description

Detailed Description of the Invention

[0001]

The present invention is applied to automobiles and the like.
The present invention relates to an accelerator pedal for a vehicle.

[0002]

2. Description of the Related Art An accelerator pedal of an automobile comprises a lever portion having an intermediate portion rotatably supported by a shaft and a hook portion located at an upper end of the lever portion and connected to an accelerator cable. There are many things. The lever part and the hook part may be separately manufactured and fixed, or may be integrally manufactured (for an example of the integrated part, see Japanese Utility Model Publication No. 2-14111).

4 and 5 are of the latter type, namely
It shows that the lever part and the hook part are manufactured separately. In this figure, 1 is an accelerator pedal, 2 is a lever part which is a part of the accelerator pedal, and 3 is a hook part which is fixed to the upper end by welding. A footrest portion 4 is integrally attached to the lower end of the lever portion 2, and a shaft 5 is attached to the middle portion. The shaft 5 is rotatably supported by a bracket 7 attached to a dash panel 6 that is a vehicle body side member. As a result, when the foot rest portion 4 is stepped on, the lever portion 2 turns about the shaft 5 as the turning center.

The hook portion 3 has an opening 8 opened upward, and an accelerator cable 10 having a stopper 9 attached to an end is passed through the opening 8. As a result, the footrest 4
When is depressed and the lever portion 2 rotates about the shaft 5 as the center of rotation, the accelerator cable 10 is pulled. An unillustrated tip of the accelerator cable 10 is connected to the throttle valve.

A weight 11 is attached to the lever portion 2 by welding. This weight 11
Is to prevent the lever portion 2 from vibrating due to the vibration from the engine transmitted through the accelerator cable 10 and the hook portion 3, and is set to an appropriate weight.

A weight having a proper weight for the lever portion 2.
By attaching 11, the vibration is not transmitted to the lever portion 2 and the footrest portion 4, and the driver's discomfort is eliminated.

[0007]

However, in the structure using the weight as described above, although the vibration is effectively prevented, the weight is increased by the weight of the weight. The present invention has been made in view of this point, and an object of the present invention is to provide an accelerator pedal for a vehicle that can obtain an effect of preventing vibration without using a weight.

[0008]

Means for Solving the Problems The present invention is, as a means for solving the above problems, a lever portion having an intermediate portion rotatably supported by a shaft, and an accelerator cable connected to an upper end of the lever portion. In a vehicular accelerator pedal including a hook portion connected to, a bush is interposed at a connecting portion between the lever portion and the hook portion.

Further, the outer circumference of the bush is spherical.

Further, flanges are formed at both ends of the bush, and the flange portions are engaged with the upper and lower edges of the hook portion.

Further, a slit is provided vertically on the hook portion, and a protrusion is formed on the bush so as to be fitted into the slit.

[0012]

With this structure, even if the vibration from the engine is transmitted to the hook through the accelerator cable, the vibration is absorbed by the bush and is not transmitted to the lever. Since the outer circumference of the bush is spherical, the hook part hits the bush at the most bulged part of the spherical surface, so a minute movement is allowed, and this minute movement blocks the vibration transmission to the lever part. become.

Further, by forming flanges at both ends of the bush and engaging the flange portions with the upper and lower edges of the hook portion, it is possible to prevent the hook portion from moving along the lever portion. it can.

Further, since the slit is provided in the hook portion in the vertical direction, and the bush is formed with the protrusion that fits into the slit, the bush can be prevented from rotating.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The hook portion 3 is provided with a hole 12, and the lever portion 2 is fitted into the hole 12 via a rubber bush 13. Therefore, the diameter dimension of the hole 12 is larger than the outer dimension of the lever portion 2, and the bush 13 is set so as to be slightly compressed.

As shown in FIG. 2, the bush 13 has a spherical outer surface 13a, so that the hook portion 3 hits the bush 13 at the most bulged portion of the spherical surface, and a small gap is formed in the other portions. Therefore, a slight movement is allowed in the direction indicated by arrow A in the figure. Due to this slight movement, the vibration from the engine is not transmitted to the lever portion 2. It is also possible to absorb the play of the accelerator cable 10.

Further, flanges 13 are provided on both ends of the bush 13.
b is formed, and the flange portion 13b engages with the upper and lower edges of the hook portion 3, whereby the hook portion 3 can be prevented from moving along the lever portion 2.

As shown in FIG. 3, the hook portion 3 is provided with a vertical slit 14. On the other hand, the bush 13 is formed with a ridge 13c fitted in the slit 14. As a result, it is possible to prevent the bush 13 from rotating by inserting the protrusion 13c into the slit 14.

The bush 13 and the lever portion 2 are in a press-fitting relationship. Therefore, the hook portion 3 does not move except for a slight movement, and can be positioned and fixed basically in the same manner as welding.

In the embodiment described above, the bush
Although the outer circumference has a spherical shape as described as 13, the spherical shape does not have to be a perfect circle when viewed in a cross section, and the surface has fine sawtooth-shaped irregularities. Good. By doing so, the spring constant of the bush 13 is reduced, and the vibration absorption capacity is increased.

[0021]

Since the present invention is the accelerator pedal for a vehicle constructed as described above, it is possible to absorb the vibration transmitted from the engine through the accelerator cable. Also, the play of the accelerator cable can be absorbed. It is lighter than the one using the conventional weight.
