Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pedal having a bracket integral with a hinge,

The present invention relates to a structure of a clutch pedal of a vehicle, and more particularly, it is possible to set a plurality of pedal ratios so as to provide a suitable pedal ratio according to the amount of engine displacement, reduce the number of injection molds, And a hinge integrated type bracket which can be secured.

A clutch is a device for disconnecting or connecting power transmission between an engine and a transmission in a vehicle equipped with a manual transmission. When a driver on the driver's seat depresses the clutch pedal, transmission of power from the engine to the transmission is cut off, It is configured to allow power transmission when the pedal is tilted.

A typical clutch system is classified into mechanical type and hydraulic type. Hydraulic type is a hydraulic type that can generate a hydraulic pressure by the rotational force of a clutch pedal (in a master cylinder) to operate the clutch, so that the pedal can be depressed with a smaller force.

On the other hand, the recent vehicle sales strategy constitutes the product lineup with various engine displacement in one vehicle considering various requirements of many consumers. Depending on the vehicle, quasi-quadruple vehicles usually comprise four to six product lineups, but even with the same model of vehicle, the power to intercept the clutch for shifting increases and the force on the clutch increases as the engine displacement changes .

If the model of the same model is used, the pedal effort must be maintained at a similar level, even if the engine displacement varies, so that the pedal ratio must be changed. The change of the general pedal ratio is performed by moving the pivotal position of the pedal mounted on the pedal housing (i.e., the mounting position of the hinge pin engaged with the clutch pedal).

1 is a view showing a conventional plastic material pedal housing (a) and a steel material pedal housing (b).

As shown in Fig. 1, the conventional pedal housing is made of a plastic material (a) or a steel material (b). In the case of the steel re-pedal housing (b), a hole for mounting a hinge pin is formed through a piercing method or the like, and the hole position of the hole is changed to cope with specifications according to the engine displacement. In the case of the plastic reed pedal housing (a), the hole to which the hinge pin is mounted is formed by the shape of the injection mold, and if the position of the hole is changed, the injection mold itself must be modified or newly manufactured.

That is, the conventional pedal housing has a problem that the hole for mounting the hinge pin is required to be newly punched to cope with the specification according to the amount of engine displacement, or the injection mold must be modified or new for each specification.

In addition, since the pedal housing is manufactured for each specification, it is difficult to maintain the inventory management and stable quality. Therefore, a pedal capable of changing the pedal ratio but reducing the cost is required.

In addition, although not shown, in order to solve the above-mentioned problem, when a bracket for mounting a hinge pin is manufactured by a double injection molding method, it is difficult for a user to rotate the injection mold into a hot injection mold, There is a drawback that the investment cost is excessive.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

SUMMARY OF THE INVENTION The present invention is conceived to solve the problems of the conventional art described above, and it is an object of the present invention to provide a clutch pedal having a desired pedal ratio according to a specification of a vehicle using a first bracket with a hinge pin extended and a second bracket with a hinge hole punctured And an object of the present invention is to provide a structure of a pedal having a hinge-integrated bracket that can be easily assembled, thereby significantly reducing the possibility of injury to a worker and reducing facility investment costs.

Further, in the present invention, when the clutch pedal fails or is replaced, the pedal arm and the hinge pin formed therein are replaced without replacing the entire clutch pedal, Another object is to provide a structure of a pedal having an integral bracket.

The technical objects to be achieved by the present invention are not limited to the above-mentioned technical problems, and other technical subjects which are not mentioned can be clearly understood by those skilled in the art from the description of the present invention .

According to an aspect of the present invention, there is provided a pedal assembly comprising: a first bracket mounted on one side of a pedal housing, the first bracket extending from one side of the pedal housing to allow the pedal arm to pivot; A second bracket mounted on the other side of the pedal housing and having a hinge hole formed therein so that an end of the hinge pin can be inserted; Wherein the center of the hinge pin is formed at a position spaced from the center of the first bracket.

 In addition, in the structure of the pedal having the hinge-integrated bracket according to the embodiment of the present invention, it is preferable that the first bracket is formed with two or more fastening holes so as to be engaged with the pedal housing via the screw.

In addition, in the structure of the pedal having the hinge-integrated bracket according to the embodiment of the present invention, it is preferable that the fastening holes are arranged to be equally spaced from each other along the circumference of the first bracket.

Meanwhile, in the structure of the pedal having the hinge-integrated bracket according to the embodiment of the present invention, the first bracket includes a seat portion inserted into a seating hole formed in the pedal housing and extending from the inner side thereof, And an outermost portion formed on an outer side of the seating portion and having a diameter relatively larger than a diameter of the seating portion; .

In addition, in the structure of the pedal having the hinge-integrated bracket according to the embodiment of the present invention, it is preferable that one or more protrusions protrude from the seating portion to be inserted into the flow prevention groove formed in the pedal housing.

In addition, in the structure of the pedal having the hinge-integrated bracket according to the embodiment of the present invention, it is preferable that the projections are formed in two or more, and are arranged to be spaced apart from one another along the circumference of the seating portion of the first bracket.

Further, in the structure of the pedal having the hinge-integrated bracket according to the embodiment of the present invention, the axial height of the protrusion is relatively lower than the axial height of the seating portion so that the outermost portion, the protrusions, and the seating portion have steps in the axial direction .

According to the present invention having the above-described structure, since the first bracket with the hinge pin extended and the second bracket with the hinge hole are assembled, the pedal ratio required according to the vehicle can be easily realized, and the possibility of injury to the operator is remarkably reduced, The investment cost for production and automation equipment is remarkably reduced.

Although the injection mold of each pedal housing has to be modified or separately manufactured according to the pedal ratio in the related art, in the structure of the present invention, only one injection mold is manufactured and only the angle at which the first bracket and the second bracket are assembled is adjusted, It is possible to manufacture a plurality of pedal housings having different ratios.

In addition, the present invention has a plurality of protrusions to be inserted into the pedal housing and has a stepped structure applied to the first bracket, so that the bracket can be prevented from being rotated or axially spaced.

Further, the present invention can reduce the number of components because the hinge pin can be integrally integrated with the first bracket, and the replacement of the first bracket and the second bracket enables replacement of the clutch pedal or tuning of the pedal ratio. There are advantages.
