[0001]

TECHNICAL FIELD The present invention relates to a parking brake for an automobile.

[0002]

2. Description of the Related Art FIGS. 4 and 5 show a part of a parking lever of a conventional manual parking brake which is generally used. The parking lever 1 is arranged between the driver's seat and the passenger seat of the automobile, and is supported by a support shaft 4 of a support fitting 3 fixed to a panel 2 of the vehicle body. The parking lever 1 can be rotated around the support shaft 4, and when the driver pulls up the grip portion 6, the parking lever 1 can be rotated to a position indicated by a chain line.

A known ratchet mechanism inside the parking lever 1 locks the parking lever 1 at the position indicated by the alternate long and short dash line. The parking lever 1 is provided with a brake release button 7 at its front end, and when the driver presses the brake release button 7, the parking lever 1 is released from the locked state and can be returned to its original position.

A mounting shaft 9 for the equalizer 8 is provided below the rear end of the parking lever 1, and the front end of the equalizer 8 is pivotally attached thereto. A pair of brake cables 10 are connected to the rear end of the equalizer 8. Therefore, when the parking lever 1 is pulled up to the position indicated by the alternate long and short dash line, the brake cable 10 is pulled forward by the operating force, and the braking force is applied to the rear wheel side left and right wheels 11 shown in FIG. At this time, the equalizer 8 operates like a jumble and plays a role of evenly distributing the operating force of the parking lever 1 to the left and right wheels 11 of the automobile. The brake cable 10 shown in FIG. 5 is supported by a support bracket 12, and is bent in the lateral direction and disposed on the side portion of the vehicle body in order to avoid the fuel tank 13 behind it.

On the other hand, FIG. 7 shows a pulley type parking brake. In this type of parking brake, a pulley-type equalizer 15 is arranged between the parking lever 1 and the brake cable 14. When the parking lever 1 is pulled up, the pulley-type equalizer 15
The operating force of the parking lever 1 is applied to the left and right wheels 11,
It is a method of even distribution.

[0006]

By the way, in recent years, as a measure against a collision from the rear of the vehicle, the fuel tank is moved from the rear portion of the vehicle body to the front portion. Therefore, as shown in FIG. 5, when the fuel tank 13 is moved forward, the front end portion of the fuel tank 13 moves to the position indicated by the alternate long and short dash line and comes into contact with the brake cable 10. For this reason,
It is conceivable to move the positions of the equalizers 8 and 15 and the support bracket 12 forward. However, the length between the equalizers 8 and 15 and the parking lever 1 is limited. It is also possible to move the position of the parking lever 1 itself forward, but the parking lever 1
Operability becomes worse.

The present invention has been made in view of the above problems, and an object thereof is to provide a parking brake in which the fuel tank does not hinder the disposition of the parking cable even when the fuel tank is moved forward.

[0008]

The above object is to provide a manual parking lever which is disposed on the side of a driver's seat of an automobile and which rotates about a support shaft as an axis, and an operation force of the parking lever. A brake cable that transmits to
In a parking brake provided with an equalizer connected between the parking lever and the brake cable, which evenly distributes the operating force of the parking lever to the left and right wheels, the equalizer is provided more than the connecting portion of the equalizer and the parking lever. This is achieved by a parking brake characterized by being placed in front.

BEST MODE FOR CARRYING OUT THE INVENTION A parking brake according to an embodiment of the present invention will be described below with reference to the drawings. The same components as those in the conventional example will be described with the same reference numerals, and detailed description thereof will be omitted.

1 to 3 show a parking lever part 1 of a parking brake according to the present invention, of which FIGS. 1 and 2 show a state in which the parking brake is not operated, and FIG. 3 shows a parking brake. Shows that the parking lever 1 is in operation, and the parking lever 1 is pulled up.

As shown in the figure, a mounting bracket 18 of an arm 17 is fixed to the vehicle body just before and at the same height as the support shaft 4 of the parking lever 1. At the rear end of the mounting bracket 18, one end of the arm 17 is connected to the shaft portion 19.
To be rotatable. Arm 17
A front lever 21 of the equalizer 20 is rotatably attached to the other end of the same by a shaft portion 22.

The rear lever 23 of the equalizer 20 is rotatably attached to the attachment shaft 9 of the equalizer 20 provided at the lower rear end of the parking lever 1. Therefore, this mechanism is a link mechanism in which the support shaft 4 and the shaft portion 19 are fixed shafts, and the mounting shaft 9 and the shaft portion 22 are movable shafts. In addition, this mechanism is provided with the shaft portions 19 and 22 of the arm 17.
Is the same as the length between the support shaft 4 and the mounting shaft 9, and the length between the support shaft 4 and the shaft portion 19 is the same as the length between the mounting shaft 9 and the shaft portion 22.

As shown in FIG. 2, a support bracket 26 that supports the brake cable 25 is provided behind the support fitting 3 that supports the parking lever 1.
The support bracket 26 is arranged L ahead of the position of the support fitting 12 in the conventional example shown by the alternate long and short dash line. Further, the front end portion of the brake cable 25 is connected to the equalizer 20, but is longer than that of the conventional example because it is disposed in front of the support shaft 4 of the parking lever 1. The front portion of the fuel tank 13 is shown in FIG.
It is arranged at the same position as the one-dot chain line shown in.

The structure of the parking brake according to the embodiment of the present invention has been described above. Next, its operation will be described.

From the position of the parking lever 1 shown in FIG. 1, in order for the driver to operate the parking brake,
When the parking lever 1 is pulled up, the parking lever 1 is locked as shown in FIG. At this time, the mounting shaft 9 of the parking lever 1 rotates forward about the support shaft 4, and the equalizer 20 moves forward by the operation of the parallel link mechanism. Therefore, the brake cable 25 connected to the equalizer 20 is pulled forward, and the left and right wheels 11 are braked.

As described above, since the parking brake according to the present embodiment is provided with the link mechanism, the operating force of the parking lever 1 can be sufficiently transmitted to the brake cable 25. Further, since the pulling margin of the parking lever 1 is also the same as the conventional one, the brake operation which is the same as the conventional one becomes possible. Further, since the equalizer 20 is arranged in front of the vehicle body with respect to the support shaft 4 of the parking lever 1, even if the fuel tank 13 is arranged in front of the support shaft 4 by that amount, the equalizer 20 does not come into contact with the brake cable 25.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiments, the equalizer 20 is arranged in front of the support shaft 4 of the parking lever by using the link mechanism. However, the arm 17 of the link mechanism and the mounting bracket 18 are not always required. Does not need However, in such a case, in order to prevent vertical displacement or lateral displacement of the equalizer 20, a guide member having a hole penetrating the front lever 21 or the rear lever 23 of the equalizer 20 may be attached to the vehicle body side.

Further, although the above embodiment has been described by using the squeeze-belt type equalizer, the present invention can of course be applied to the pulley type equalizer described above.

[0020]

As described above, according to the present invention, since the equalizer is arranged in front of the support shaft of the parking lever, the position of the parking lever is changed even if the fuel tank is moved in front of the vehicle body. It is possible to prevent the brake cable from coming into contact with the fuel tank without having to do so and to increase the degree of freedom in arranging the parking cable.
