Abstract

(57) [Summary] (Correction) [Purpose] To easily deal with changing the lever ratio. [Structure] The main bracket 1 on the clutch pedal 4 side and the sub-bracket 10 on the master cylinder 14 side are formed as separate bodies, and the both brackets are joined together in alignment with the hole 6 position at the working end of the pedal.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a clutch pedal bracket.

[0002]

[Prior Art]

 In the conventional clutch pedal bracket, the clutch pedal is pivotally attached to the clutch pedal bracket, the master cylinder is attached, and the hole at the working end of the pedal is connected to the rod of the master cylinder. The applicant of the present invention has proposed, in Japanese Utility Model Laid-Open No. 63-18334, a clutch pedal device in which the foot force direction when the pedal is stepped is curved instead of arcuate to improve the pedaling operation.

[0003]

[Problems to be solved by the device]

 The lever ratio of the clutch pedal, that is, the ratio of the distance from the pivot point to the driving end and the operating end, may need to be changed depending on the pedaling force of the vehicle, the disengagement of the clutch, and the connection.

However, in the conventional clutch pedal bracket as described above, since the distance between the pivot point and the master cylinder axis is constant, the clutch pedal bracket needs to be largely changed in order to change the lever ratio. Yes, it was not possible to handle a wide variety of small vehicles.

An object of the present invention is to provide a structure of a clutch pedal bracket that can easily cope with a change in lever ratio.

[0006]

[Means for Solving the Problems]

 According to the present invention, the clutch pedal bracket is formed separately from the main bracket for pivotally mounting the clutch pedal and the sub-bracket for mounting the master cylinder, and the sub-bracket is fitted according to the hole position of the working end of the clutch pedal. Is connected to the main bracket.

It is preferable that the two brackets are connected to each other by spot welding.

[0008]

[Action]

 In the structure of the clutch pedal bracket configured as described above, for example, when increasing the lever ratio, the length from the pivot point to the hole position of the working end becomes shorter, and therefore, from the pivot point to the master cylinder axis line. Distance becomes smaller. Therefore, in order to increase the lever ratio, the sub-bracket is shifted toward the pivot side and welded to the main bracket by the amount that the distance is shortened.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, a clutch pedal bracket generally designated by reference numeral A is composed of a main bracket 1 and a sub-bracket 10, and both 1 and 10 are spot-welded in a manner described later.

The main bracket 1 is formed of a plate material in a U shape when viewed from above, and flange portions 2 and 2 are formed on one side of the upper portion (left side in the drawing). A clutch pedal 4 is pivotally attached to a through hole 3, 3 which is a pivot point formed in the middle of the bracket 1 via a shaft (not shown). A through hole 6 is bored at the opposite operating end of the step portion 5, which is the drive end.

On the other hand, the sub-bracket 10 is formed of a plate material in a U-shape when viewed from above, and has flange portions 11 and 11 facing the above-described flange portions 2 and 2. A large-diameter through hole 12 is formed in the central portion of the sub-bracket 10, and stud bolts 13, 13 are provided upright around the through-hole 12. A master cylinder 14 is attached to these bolts 13 and 13 through attachment holes 15 and 15. Then, the rod 16 of the master cylinder 14 penetrates the through hole 12, and the yoke 17 at the tip of the rod 16 is pin-connected to the through hole 6.

During assembly, the sub-bracket 10 is welded to the main bracket 1 in accordance with the distance L3 between the through hole 3 and the axis of the master cylinder 14, that is, the position of the through hole 6. Next, the master cylinder 14 is attached to the sub-bracket 10, and the yoke 17 is pin-connected to the through hole 6.

When changing the lever ratio (L1 / L2) of the clutch pedal 4, for example, when increasing the lever ratio, that is, when decreasing L2, the position of the through hole 6A, that is, the through hole 3 and the axis of the master cylinder 14, The sub-bracket 10 is shifted downward so that the distance L3 becomes the distance L3A and is welded to the main bracket 1.

[0015]

[Effect of the device]

 Since the present invention is configured as described above, it is possible to easily change the lever ratio and finely adjust the pedal effort, the clutch disengagement, and the joint condition for each vehicle type.

Further, it can be implemented with a simple structure without a large increase in cost.
