Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle clutch pedal, comprising a pedal arm for rotating motion, a clutch shaft connected to the pedal arm, a master cylinder connected by the clutch shaft and a push rod, and a left and right bracket. In the pedal, a screw-shaped arm shaft (11) connected to the pedal arm, a stopper (12) installed in the arm shaft, a check valve (13) having the same role as that incorporated in the existing master cylinder, Bushing connector (18) connecting the pedal arm (10) to the right bracket (20) by the bushing (15) and the fixing bolt (21), and loosely screwed arm shaft (11) It is made of a shaft cylinder (40) to be built through to convert the rotary motion directly into a piston movement.

That is, the shaft of the existing clutch pedal is to act as a master cylinder, by applying a loose screw method between the arm shaft (11) and the shaft cylinder (40) acting as a piston to perform a direct piston movement of the rotational movement of the arm. Therefore, when the driver steps on the pedal arm 10, the arm shaft 11 rotates in the shaft cylinder 40 in a screw manner and moves to the left to form hydraulic pressure, and a separate master cylinder space is not required. The cost can be reduced by reducing the number, and the clutch effort can be improved by reducing the loss due to the existing mechanical friction.

Description

Clutch pedals for vehicles {Clutch-pedal for vehicles}

The present invention relates to a clutch pedal for a vehicle, and more particularly, to a clutch pedal for a vehicle that can improve the clutch response by reducing losses due to mechanical friction without requiring a separate master cylinder.

In general, the current commercial clutch pedal in production, as shown in Figure 1, the pedal arm (1) to be rotated, the clutch shaft (2) connected to the pedal arm, the clutch shaft and the push rod Master cylinder (4) and left and right brackets (5,6) connected by (3), the operation method is the pedal arm (1) rotates when the driver presses the pedal, the clutch shaft (2) While rotating, the push rod 3 of the master cylinder 4 is linearly moved to form hydraulic pressure.

However, the problems of the system as described above, the problem of securing a separate space for the master cylinder, the efficiency degradation generated in the process of changing the rotational motion to a linear motion, loss due to the contact between the push rod and the master cylinder As a result, a disadvantage arises in that the driver's pedaling ability is increased.

Accordingly, the present invention has been invented to solve the above problems, by changing the clutch shaft to a screw method, the vehicle can be improved clutch response by reducing the loss due to mechanical friction without the need for a separate master cylinder The purpose is to provide a clutch pedal.

1 is a perspective view of a clutch pedal as a prior art;

Figure 2 is an operation diagram when not operating the clutch pedal according to the invention,

The present invention for achieving the above object is a vehicle for the pedal arm, the clutch shaft is connected to the pedal arm, the master cylinder is connected by the clutch shaft and the push rod and the left and right brackets for rotational movement A clutch pedal comprising: a screw arm shaft connected to the pedal arm, a stopper installed in the arm shaft, a check valve having the same role as that incorporated in an existing master cylinder, and a pedal arm by a bushing and a fixing bolt. The bushing connector is connected to the right bracket, and a loose screw-type arm shaft built through the oil seal, characterized in that consisting of a shaft cylinder for converting the rotary motion directly to the piston movement.

In addition, a reservoir connector is connected to the center upper end of the shaft cylinder, the oil pipe connector for connecting the oil pipe is connected to the left side of the shaft cylinder through the left bracket.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a diagram illustrating an operation when the clutch pedal according to the present invention is not operated, and FIG. 3 is a diagram illustrating an operation when the clutch pedal according to the present invention is operated. As shown, the present invention is a pedal arm 10 to be rotated, a screw-shaped arm shaft 11 connected to the pedal arm, a stopper 12 installed in the arm shaft, and the existing master Check valve 13 and the bushing connector 18 to connect the pedal arm 10 to the right bracket 20 by the bushing 15 and the fixing bolt 21, and the same as the built-in cylinder, Loose screw type arm shaft 11 is built through the oil chamber 14 is made of a shaft cylinder 40 to convert the rotational movement directly to the piston movement.

Here, the reservoir connector 16 is connected to the center upper end of the shaft cylinder 40, and the oil pipe connector 17 for connecting the oil pipe to the left side of the shaft cylinder 40 is connected via the left bracket 30. .

In other words, the present invention is to change the "A" sub-shape in Figure 1, so that the clutch hydraulic pressure can be formed in the shaft cylinder to eliminate the need for a separate master cylinder.

That is, the shaft of the existing clutch pedal is to act as a master cylinder, by applying a loose screw method between the arm shaft (11) and the shaft cylinder (40) acting as a piston to perform a direct piston movement of the rotational movement of the arm. That is, as shown in FIG. 3, when the driver steps on the pedal arm 10, the arm shaft 11 rotates in the shaft cylinder 40 in a screw manner and moves to the left to form hydraulic pressure.

Here, the clutch arm of the pedal arm moves 15mm to the left, but it is not a problem because it does not affect the operability.

According to the present invention described in detail as described above, a separate master cylinder space is not required, which is advantageous in layout, as well as reducing the number of parts, thereby reducing the cost and reducing the loss due to the existing mechanical friction. By reducing the clutch response can be improved.
