The present invention relates to a clutch damper disk assembly having a multi-friction member, and more particularly, a first press for connecting the first friction member in contact with the flange of the hub and the second friction member in contact with the intermediate disk member to rotate integrally. A clutch damper disk assembly having a multi-friction member using a member.

Power from the engine of the vehicle is transmitted to the flywheel through the crankshaft, which is transmitted to the disc pad of the clutch disc assembly. The engine is operated even when the gear is neutral, and thus vibration is transmitted through the disc pad to the entire clutch disc assembly. To generate noise. To solve this problem, the structure that generates friction in the clutch disc assembly is adopted.

13 is a plan view of a multi-friction member used in a conventional clutch damper disk assembly. As shown in FIG. 13, the multiple friction member 40 used in the conventional clutch damper disk assembly has a second friction member 45 for connecting the first friction member 41 and the second friction member 45. The grooves 46 were formed in the inner diameter of and the protrusions 42 engaged with the grooves 46 were formed in the outer diameter of the first friction member 41. Then, the first pressing member 50 is placed on the upper surface of the first friction member 41, and the second pressing member 45 is placed on the second friction member 45 through the protrusion 47 of the second friction member 45. 52) was deployed.

The first friction member 41 is provided to friction with the flange on the flange of the hub to which the output shaft transmitted from the clutch disk assembly is coupled, and the intermediate disk member installed inside the input disk member coupled to the disk pad. 2 is characterized in that the friction member 45 is installed separately.

In the damper disk assembly having the multi-friction member 40, the torsional vibration with small amplitude is attenuated by the friction of the flange of the hub and only the first friction member 41, and the vibration with the large amplitude is the intermediate disk member and the second friction member. (45) rubs and attenuates.

The first pressing member 50 installed on the first friction member 41 has a structure in which the movement is not limited with respect to the first friction member 41 and can rotate freely. Therefore, when the torsional vibration is transmitted, there is a problem in that the first pressing member 50 slides with respect to the first friction member 41 to form a friction surface. As a result, the friction between the intended first friction member 41 and the flange of the hub does not occur properly.

As the friction surface is changed, the friction coefficient related to the friction surface is changed, and the damping action is lowered, thereby preventing the torsional vibration transmitted from the engine.

If this phenomenon continues, the gears of the transmission collide with each other while the gears of the vehicle are in the neutral position to generate a noise called a neutral stroke.

In addition, in the manufacturing process of the clutch damper disk assembly, first, the multi-friction member 40 is assembled, and the assembled multi-friction member 40 is assembled to the input side disc member (not shown), and the first pressing member 50 is Since the first friction member 41 is not fixed or restrained, there is a problem that the first pressing member 50 is lost in the assembled multi-friction member 40.

In addition, the conventional multiple friction member 40 has a structure in which the first friction member 41 and the second friction member 45 are directly coupled, and the protrusions 42 of the first friction member 41 are second. It was to be placed in the groove 46 of the friction member 45. However, since the projection 42 of the first friction member 41 is not a structure which is merely placed in the groove 46 of the second friction member 45 and fixed or restrained, the multi-friction member 40 is connected to the input side disk member. If an impact or shaking occurs in the assembling process, the protrusion 42 of the first friction member 41 easily escapes the groove 46 of the second friction member 45, and thus the protrusion 42 of the first friction member 41. Is often assembled to deviate from the groove 46 of the second friction member 45, which is a problem.

These protruding pieces 31 are about 16 when the outer diameter is about 5.5 cm.

Hereinafter will be described with respect to the assembly and the mutual force transfer relationship of each component member configured as described above.

As shown in FIG. 4, in the first pressing member 25 of the multi friction member 10, the engaging groove 27 of the first pressing member 25 is the engaging projection 14 of the first friction member 11. The upper surface of the coupling groove 27 of the first pressing member 25 is coupled to the locking projection 15 of the coupling protrusion 14. The first pressing member 25 couples the pair of guide pieces 29 of the insertion portion 28 to both sides of the second protrusion 22 of the second friction member 20 to the second friction member 20. Combined. The second pressing member 30 is coupled to the second friction member 20 while the first protrusion 21 of the second friction member 20 is inserted between the protruding pieces 31 of the second pressing member 30. .

Hereinafter, the operation and effect of the clutch damper disk assembly having a multi-friction member according to a preferred embodiment of the present invention having the above configuration will be described in detail.

Since the insertion portion 28 of the first pressing member 25 is disposed horizontally on the upper surface of the second friction member 20, the outer diameter portion of the first pressing member 25 is in contact with the input side disc member 1. Thereby, sufficient pressing force can be exerted with little deformation.

Since the first pressurizing member 25 is engaged with the first rubbing member 11 so that a relative rotational movement with the first rubbing member 11 is limited, the first pressurizing member 25 and the first rubbing member 11 are separated from each other. No friction between the upper surface or friction between the first pressing member 25 and the input side disc member 1 occurs. As a result, the friction action occurs between the flange portion 6 surface of the hub 5 and the first friction member 11, and thus there is a smooth damping action to offset the torsional vibration transmitted from the engine. Therefore, the gear teeth generated in the transmission collide with each other to reduce the noise generated.

The first protrusion 21 formed on the second friction member 20 functions to couple the second friction member 20 and the input side disc member 1, and the second protrusion 22 has the first pressing member 25. ) And the second friction member 20 to rotate integrally.

The present invention does not adopt a structure in which the first friction member 11 is placed above the second friction member 20 and the insertion portion 28 of the first pressing member 25 to which the first friction member 11 is coupled is provided. Since the structure adopts the structure in which the second friction member 20 is coupled to the second projection 22, the first friction member 11 is prevented from being displaced with respect to the second friction member 20.

In addition, since the insertion portion 28 of the first pressing member 25 is coupled to and restrained by the second projection 22 of the second friction member 20, the assembled multi-friction member 10 receives the input side disk member 1. In the process of coupling to the first projection 21 of the second friction member 20 in the state of matching the groove of the input side disk member (1) even when the shock or shaking occurs when the first pressing member (25) Since the movement is constrained along the second projection 22, it is prevented from being displaced with respect to the second friction member 20.

In addition, since the first pressing member 25 and the first friction member 11 do not rub, they are worn on the upper surface of the first friction member 11, so that the first pressing member 25 and the first friction member 11 As the gap between the upper surfaces becomes larger, the pressing force of the first pressing member 25 is prevented from being lowered.

According to the clutch damper disk assembly having a multi-friction member according to a preferred embodiment of the present invention having the configuration as described above, because the first pressing member is combined with the first friction member to move integrally without relative movement, the first pressing member The friction surface is not formed between the first friction member and the first friction member. Therefore, there is only one friction surface between the first friction member and the flange of the hub. The smooth damping action is advanced by the friction between the first friction member and the flange surface of the hub to offset the torsional vibration transmitted from the engine, thereby reducing the gear noise generated in the transmission.

Due to the engaging projection of the first friction member, the first pressing member coupled to the first friction member does not flow separately so that the first pressing member may be lost from the assembled multi-friction member even if an impact or shaking occurs during the assembly of the clutch damper disk assembly. There is an advantage that there is no, on the contrary, since the first friction member is coupled to the first pressing member through the locking projection, the first friction member is prevented from falling out and being lost.

The projections of the second friction member used to join the input side disk member and the second friction member can also be used to join the second friction member and the first pressing member, so that there is no advantage of forming an additional coupling structure.

A large friction force is generated by setting the pressing force of the second pressing member to be larger than the pressing force of the first pressing member. At this time, the torsional vibration having a large displacement angle is effectively attenuated by the characteristics of large rigidity and large frictional force. In this case, when a large frictional force is generated, wear of the second friction member is relatively faster than that of the first friction member. Accordingly, relative movement in the axial direction is required for the first friction member and the second friction member. In the present invention, the relative movement in the axial direction is enabled by the engagement of the projection of the second friction member and the insertion portion of the first pressing member.

Since the first projection 21 of the second friction member is connected to the input side disk member and the insertion portion of the first pressing member is constrained by the second projection 22 of the second friction member, the first friction member Although the first friction member does not move in the circumferential direction with respect to the second friction member even though the first friction member moves in the axial direction with respect to the second friction member, there is an effect that the first friction member and the second friction member are always out of position. .

The insertion portion of the first pressing member is inserted into the second projection 22 on the upper surface of the second friction member and is disposed horizontally on the upper surface of the second friction member, and the outer diameter of the first pressing member contacts the input side disk member to deform. There is an effect of generating a sufficient pressing force with little generation.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will cover such modifications and variations as fall within the spirit of the invention.
