Description

Damper spring structure of clutch disc {DAMPER SPRING STRUCTURE OF CLUTCH DISC}

The present invention relates to a damper spring structure structure, and more particularly, to a damper spring structure of a clutch disk in which the damper spring is a double-diameter structure to increase the compression length of the spring.

In general, the clutch is mounted between the engine and the transmission to cut off and connect the power of the vehicle to allow the vehicle to stop, start, and shift.

In addition, the clutch disk is equipped with a damper spring to reduce the gear rattle noise (Rattle Noise) caused by the angular acceleration fluctuations of the engine and the gear backlash of the transmission to improve the quietness of the vehicle.

In addition, the high friction coefficient of the compression load (forced by the spring) of the clutch cover and the disc facing (Disc Facing) ensures a stable transmission of power even when the clutch pedal is driven.

In order to increase the compression field of the damper spring, the mounting position of the spring must be moved toward the outer diameter of the disc. In this case, the area of the disc pacing is reduced and the heat capacity of the disc is reduced, which adversely affects the burnout of the disc, and thus is not generally applied.

In addition, when it is impossible to cope with rattle noise with a damper disk having a small damping angle, dual mass fly wheels are being applied, but there is a problem that the price is high (6-7 times that of a normal fly wheel).

1A and 1B are views showing the structure of a conventional clutch disk,

FIG. 1A shows the front shape of the clutch disc, and FIG. 1B is a side cross-sectional view of FIG. 1A.

Referring to the configuration of the conventional clutch disk with reference to the drawings, the hub plate (1) in the middle, the main plate (3, 5) located on the upper and lower sides of the hub plate (1), and the upper main plate (3) The pacing 7 is attached to the end of the c), and the stopper 6, the rivet 4, and the like.

The facing 7 is in contact with the flywheel of the engine and the pressure plate of the clutch cover and has a stable high coefficient of friction.

The damper spring 10 is formed to have the same diameter, and serves to ensure the quietness of the vehicle by performing a damper function for angular acceleration fluctuations due to the explosion of the engine and rattle noise caused by the backlash of the transmission gear. The present invention is to improve the structure of such a conventional damper spring (10).

For reference, the stopper 6 is a damper spring 10 is interlocked with the compressive strength, when the damper spring 10 is fully compressed to act as a stopper to prevent additional load on the spring to prevent the spring from being broken Play a role.

The hub plate 1 and the main plate 5 guide the damper spring 10 and form an outer structure to enable compression and stop operation of the spring.

Conventional damper spring (10) provided in the clutch disk has a limited compression field to prevent the rattle noise.

Figure 1c is a view showing the operating section of the damper spring, as shown, the clutch disk damping section of the mass production level, the size of the pacing is 225mm (outer diameter) × 150mm (inner diameter), the damper spring ( The mounting length L of 10) is 54.04 mm, the maximum compression length l is 31.84 mm, and the damping angle is about 19 degrees.

Therefore, as the optimum condition of the damper spring 10 for preventing the rattle noise, the larger the damping angle is advantageous, the smaller the rigidity of the spring is advantageous. In other words, the damping angle must be large in order to maintain a proper stopper torque safety factor for the engine power and to have small rigidity.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention aims to provide a damper spring structure of a clutch disc that can effectively improve the radical noise of a vehicle without applying a dual mass flywheel by increasing the compression length of the damper spring. do,

The damper spring structure of the present invention for achieving the above object is a damper spring provided in the clutch disk of the vehicle, the spring of small diameter (d) and large diameter (D) in order to increase the compression field of the damper spring sequentially It is characterized in that formed by a spring of a double diameter repeated.

According to the damper spring structure of the clutch disk of the present invention described above, the compression length of the damper spring is improved, which is effective in responding to rattle noise, and has an effect of eliminating consumer complaints in the field.

In addition, the compression length of the damper spring can be increased without moving the mounting position of the spring toward the outer diameter of the disk, and the heat capacity of the same damper spring is greater than that of the disk in the compression field of the same damper spring, thereby increasing the durability life of the disk.

In addition, since the damper angle can be increased, rattle noise can be improved without changing an existing mold, and thus the effect of part sharing can be expected. In addition, the cost reduction can be achieved by minimizing the application of the dual mass flywheel as the damping angle increases.

Hereinafter, preferred embodiments of the damper spring structure according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 2a is a view showing the structure of a clutch disk according to the present invention,

Figure 2b is a view showing the spring mounting length and the maximum compression field and the damping angle of the double-diameter damper spring according to the present invention.

Referring to the drawings together, in the present invention, the damper spring 30 is formed in a spring structure having a double diameter of a large diameter (D) and a small diameter (d) together to greatly increase the damping angle, thereby increasing the single mass fly wheel. Rattle noise and NVH characteristics are greatly improved.

As described above, the double-diameter damper spring 30 of the present invention is a spring having a small diameter (d) and a large diameter (D) are formed together in one spring, and the small diameter (d) and the large diameter ( D) is composed of sequentially repeated.

Looking at the characteristics of the damper spring 30 of the present invention having a double-diameter structure as follows.

As shown in Fig. 2B, the facing size of the clutch disk and the mounting length L of the spring are 225 mm (outer diameter) x 150 mm (inner diameter) and 54.04 mm (see Fig. 1C), which are the same conditions as before. The maximum compression field l of the damper spring 30 is 24.94 mm, which is shorter than that of the conventional 31.84 mm, and the damping angle is increased from 19 degrees to 24.9 degrees. That is, in the structure of the damper spring 30 of the present invention, it can be seen that the maximum compression field l and the damping angle are improved by about 31% compared with the conventional case. This is because when the damper spring 30 of the present invention having double diameters D and d is compressed, the amount to be compressed is further increased as compared with a spring having a structure having the same diameter size as in the prior art. Part is double compared with conventional straight line)

On the other hand, when the size of the damper spring 30 and the size of the clutch disk facing is different, the size of the mounting length (L), the maximum compression length (l) and the damping angle of the damper spring 30 may also change.

Therefore, the damper spring 30 structure of the present invention forms the double-diameter spring structure, thereby improving the compression field of the damper spring, which has a great effect in dealing with rattle noise, and can resolve consumer complaints in the field. .

In addition, the compression length of the damper spring can be increased without moving the spring mounting position toward the outer diameter of the disk.The contact area of the disk facing is the same so that the heat capacity of the disk does not decrease so that the heat capacity of the compression field of the same damper spring is lower than the disk. The endurance life of the cursor disk is increased.

In addition, since the damper angle can be increased, rattle noise can be effectively improved without changing an existing mold, and thus the effect of part sharing can be expected. In addition, as the damping angle increases, cost reduction can be achieved by minimizing the application of the dual mass flywheel.

Furthermore, since the development takes a long time when applying the dual mass flywheel of the present invention, when the improved damper spring disk of the present invention is applied, the vehicle development time can be shortened.

While the exemplary embodiments of the present invention have been illustrated and described as described above, various modifications and other embodiments in the construction of the apparatus may be made by those skilled in the art. Such modifications and other embodiments will be considered and included in the appended claims without departing from the true spirit and scope of the invention.
