Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 4, a vibration absorption damper 100 of a vehicle according to the present invention includes a pendulum disk 200 having a center portion coupled to a transmission input shaft in a clutch housing and having a penetration portion 240 formed therein; A guide pendulum 300 located in the penetration portion 240 of the pendulum disk 200 and provided in a plate shape and arranged in parallel with the pendulum disk 200; A guide portion 450 provided at an outer end 302 of the guide pendulum 300 and a portion 242 of the penetrating portion 240 facing the pendulum disk 200 in the radial direction; A roller 400 provided between the guide portions 450; And a main pendulum coupled to both sides of the guide pendulum, provided in a plate shape and provided parallel to the pendulum disk, with at least a portion of the piercing portion and the roller being positioned therebetween.

In detail, the pendulum disk 200 is coupled to the transmission input shaft at a central portion inside the clutch housing, and a penetration portion 240 is formed.

The pendulum disk 200 is preferably formed as a disk having a disk shape and is formed with a spline hub 220 at the center thereof and coupled with a transmission input shaft having a spline gear formed in the clutch housing between the transmission and the clutch disk .

Generally, the transmission input shaft is provided to extend from the transmission to the interior of the clutch housing, and an end thereof is engaged with a clutch disk provided inside the clutch housing. 4 shows that the vibration absorbing damper 100 of the vehicle according to the embodiment of the present invention is provided in the clutch housing.

Shock and vibration are generated in the input shaft of the transmission due to the rotational force transmitted from the crankshaft in a state in which the clutch disk is in a state of being disconnected from the crankshaft of the engine. Therefore, the vibration-absorbing damper 100 of the vehicle of the present invention is provided inside the clutch housing where the clutch disc is located, which is advantageous for effectively absorbing vibrations and preventing twisting phenomenon.

The penetration portion 240 is formed in the pendulum disk 200. The penetration portion 240 has a shape of a groove passing through both sides of the pendulum disk 200 and is preferably formed along the circumferential direction of the pendulum disk 200 It may be provided in an elongated shape.

1 to 3, the guide pendulum 300 is disposed in the penetration portion 240 of the pendulum disk 200 and is provided in a plate shape and is provided in parallel with the pendulum disk 200. [

Specifically, the guide pendulum 300 is preferably provided as a plate-shaped disk, and may be provided in parallel with the pendulum disk 200 in the penetration portion 240. The guide pendulum 300 is preferably provided to be freely movable within the penetration portion 240. FIG. 3 shows a state in which the guide pendulum 300 is provided in the penetration portion 240. FIG.

When the crankshaft of the engine, which rotates at a higher speed than the speed of the transmission input shaft at any time, is coupled to the clutch disc, the impact may be transmitted to the transmission input shaft and rotational acceleration may occur.

At this time, the rotational speed of the pendulum disk 200 also increases instantaneously due to the rotation acceleration transmitted to the transmission input shaft. However, since the guide pendulum 300 and the main pendulum 300, which are not fixed to the pendulum disk 200, The pendulum 350 is not accelerated with the pendulum disk 200 but relatively reversely moves.

That is, a part of the rotational energy transmitted to the pendulum disk 200 is stored as the relative movement energy of the guide pendulum 300 and the main pendulum 350, thereby reducing the momentary impact amount of the transmission input shaft and reducing the degree of twist of the transmission input shaft The vibration generated in the restoration process for the twist can be reduced.

The guide pendulum 300 and the main pendulum 350 provided in the penetration portion 240 of the pendulum disk 200 absorb the energy thereof while moving in the opposite direction to the rotational acceleration transmitted to the pendulum disk 200, And the like which can be generated in the vehicle.

1 to 3, in the vibration absorption damper 100 of the vehicle according to the present invention, the guide portion 450 is formed at the outer end 302 of the guide pendulum 300 with respect to the radial direction of the pendulum disk 200 And a portion 242 of the penetrating portion 240 facing the roller portion 400 and the roller 400 is provided between the guide portions 450. [

The guiding portion 450 is provided on the outer end 302 of the guide pendulum 300 with respect to the radial direction of the pendulum disk 200 and is provided on the penetrating portion side 242 facing the guiding portion 450, A space can be formed. The roller 400 is provided in the space between the guide portions 450.

A roller 400 is provided to penetrate the guide pendulum 300 and the pendulum disk 200 together and the guide pendulum 300 is provided with a roller The mass of the guide pendulum 300 may be reduced by a guide 450 formed in the shape of a groove passing through both sides of the guide pendulum 300 so that the movement of the guide pendulum 300 may be guided.

The vibration absorbing damper 100 of the vehicle of the present invention is provided with the guide portion 450 at the outer end 302 of the guide pendulum 300 and the penetrating portion side 242 facing the outer end 302, The moving region of the roller 400 can be ensured even though the through hole is not formed in the guide pendulum 300 as the moving region of the roller 400 is secured between the guide roller 300 and the roller 400. This increases the degree of freedom in designing the vibration- And the mass of the guide pendulum 300 can be prevented from being reduced. 3 illustrates that the moving region of the roller 400 is secured by the guide portion 450 formed in the guide pendulum 300 and the penetrating portion 240. [

The guide pendulum 300 moves away from the rotation center due to the centrifugal force acting on the guide pendulum 300 while the pendulum disk 200 rotates and is preferably moved in a direction perpendicular to the circumferential direction of the pendulum disk 200 240, respectively. At this time, when the pendulum disk 200 is rotated in accordance with the connection between the clutch and the crankshaft, the guide pendulum 300 moves in a direction opposite to the pendulum disk 200 in the direction of rotation of the pendulum disk 200, .

On the other hand, as the pendulum disk 200 is gradually returned to the constant velocity motion, the guide pendulum 300 returns to its original position before the rotation acceleration acts due to centrifugal force. In this case, the guide pendulum 300, which stores a part of the rotational energy, has the effect of gradually releasing the energy absorbed by returning to the correct position, thereby preventing the increased rotational energy from being transmitted to the transmission input shaft at a time It is possible to reduce the impact and vibration generated in the transmission input shaft by gradually releasing some energy.

1 and 2, in a vibration absorption damper 100 of a vehicle according to an embodiment of the present invention, a main pendulum 350 is coupled to both sides of a guide pendulum 300, 200, and at least a portion of the penetration portion 240 and the roller 400 may be positioned therebetween.

More specifically, the main pendulum 350 may be provided such that a portion of the main pendulum 350 protrudes from the guide pendulum 300 when viewed in the direction of the rotation axis, As shown in Fig. 1 and 2 show a state in which the cross section of the main pendulum 350 is larger than the cross section of the guide pendulum 300 and is engaged.

The main pendulum 350 is coupled to both sides of the guide pendulum 300 so that the roller 400 is provided in a space formed therebetween so that the guide pendulum 300 and the roller 400 are pivotally supported on the pendulum disk 200 side. Further, the main pendulum 350, which may be provided so as to have a larger mass than the guide pendulum 300 for guiding the movement direction of the pendulum, preferably increases the storage capacity of rotational energy.

The guide pendulum 300 guides the movement area of the main pendulum 350 in the penetration part 240 of the pendulum disk 200. The main pendulum 350 is a vibration absorbing damper 100), there is an advantageous effect that the structural stability is improved and the vibration absorbing effect is simply and efficiently increased.

1 to 3, in the vibration absorption damper 100 of the vehicle according to the embodiment of the present invention, the guide portions 450 may be provided so as to face each other as a curved arc-shaped groove.

In other words, the guiding portion 450 may be formed in a shape protruding from the center portion of the guiding portion 450, The space formed therebetween can be provided in the shape of an ellipse.

When the guide pendulum 300 moves in the reverse direction due to the rotation acceleration of the pendulum disk 200, the roller 400 is located close to one end of the space formed by the guide part 450, The guide pendulum 300 is returned by the centrifugal force so that the distance between the outer end 302 of the guide pendulum 300 and the opposed portion 240 facing the guide pendulum 300 is shortened, The roller 400 is also moved toward the center between the guide portions 450 so that the guide pendulum 300 can be moved farthest from the rotation center.

As a result, as the cylindrical roller 400 is positioned in the elliptical space defined by the arc-shaped guide portion 450, the guide pendulum 300 can be moved to one side in the circumferential direction without any obstacle of movement during the occurrence of rotation acceleration The guide pendulum 300 can naturally be returned to the fixed position where the guide pendulum 300 is located farthest from the rotation center by the centrifugal force.

In other words, by providing the guide portions 450 having the longest distance from the center side facing each other and the roller 400 in the space therebetween, even if the guide pendulum 300 does not have a special elastic member There is an advantage in that it can be smoothly moved to one end side in the circumferential direction and outermost in the radial direction of the pendulum disk 200.

1 to 3, in the vibration absorption damper 100 of the vehicle according to the embodiment of the present invention, the guide portion 450 includes both side portions of the outer end portion 302 of the guide pendulum 300, May be provided in a portion 242 of the penetrating portion 240, respectively.

When the guide portion 450 is present at the center of the outer end portion 302 with respect to the radial direction of the pendulum disk 200, rotation acceleration occurs, and when the guide pendulum 300 moves to one side, So that the guide pendulum 300 itself rotates in the penetration part 240. [

The rotation of the guide pendulum 300 itself may reduce the distance by which the guide pendulum 300 moves to one side due to the occurrence of the rotation acceleration and may reduce the amount of energy transferred by the guide pendulum 300, It is possible to prevent the guide pendulum 300 from returning to the home position due to the centrifugal force, which may affect the driving stability of the vibration-absorbing damper 100 of the present invention. 1 to 3 illustrate that guide portions 450 are provided on both sides of the outer end portion 302 of the guide pendulum 300 according to an embodiment of the present invention.

The guiding portions 450 are provided on both side portions of the outer side end portion 302 of the guiding pendulum 300 and are respectively provided on the penetrating portion side 242 facing the guiding portions 450, So that the driving stability of the damper can be improved simply and efficiently.

Meanwhile, in the vibration absorption damper 100 of the vehicle according to the embodiment of the present invention, the main pendulum 350 may be spaced apart from the pendulum disk 200, and a gap may be formed between the main pendulum 350 and the pendulum disk 200.

The main pendulum 350 may be moved along with the guide pendulum 300 as it is coupled to the guide pendulum 300. The main pendulum 350 may be part of the main pendulum 350, The main pendulum 350 can prevent the movement of the guide pendulum 300 when the pendulum disc 200 is in close contact with the pendulum disc 200. In order to secure the mobility of the guide pendulum 300, And may be spaced apart from each other by a predetermined distance.

1 and 2, in the vibration absorption damper 100 of the vehicle according to the embodiment of the present invention, the guide pendulum 300 and the main pendulum 350 may be integrally formed by riveting coupling 340 have.

Specifically, vibration and predetermined impact are continuously generated in the vibration-absorbing damper 100 of the present invention, and a coupling method between the main pendulum 350 and the guide pendulum 300 is important. If a screw type coupling is used, a vibration absorbing bearing or the like is additionally required to prevent the engagement between the female screw and the male screw from being separated by vibration or the like, which is economical as well as durability.

Therefore, by joining the guide pendulum 300 and the main pendulum 350 by using the riveting connection 340 of the fully-coupled type, which can not be separated after the coupling, even in the vibration-absorbing damper 100 in which vibration or the like is occasionally generated, The state can be prevented from being separated, and the structural stability can be simply and effectively improved.

1, in the vibration absorption damper 100 of the vehicle according to the embodiment of the present invention, the guide pendulum 300 is provided with a shock absorbing member 320 made of an elastic body at a point of contact with the penetrating portion 240 .

Specifically, the greater the rotational acceleration applied to the transmission input shaft, the faster the guide pendulum 300 moves within the penetration portion 240. When the guide pendulum 300 reaches one side of the penetration portion 240, And breakage or wear of the guide pendulum 300 may occur.

Accordingly, the impact absorbing member 320, which is preferably made of rubber or the like, is provided at a contact point where the guide pendulum 300 contacts one side of the penetrating part 240 when the guide pendulum 300 moves to one side due to the occurrence of rotational acceleration, And the durability of the guide pendulum 300 can be increased at the same time. 1 shows that the impact absorbing member 320 is provided at the corner of the guide pendulum 300.

3, the vibration absorbing damper 100 of the vehicle according to the embodiment of the present invention is configured such that the inner end 304 of the guide pendulum 300 and the through- And an elastic support portion 470 provided between the support portion 244 and the inner end portion 304 of the guide pendulum 300 so as to push the inner end portion 304 of the guide pendulum 300 from the center portion of the pendulum disk 200.

Specifically, the guide pendulum 300 maintains a state of being outermost from the rotation center due to the centrifugal force generated by the rotation of the pendulum disk 200. When the rotation speed of the pendulum disk 200 is low, The guide pendulum 300 can not maintain the outermost contact state, and unnecessary movement of the guide pendulum 300 can occur.

Particularly, when the centrifugal force is small and the guide pendulum 300 can not maintain the outermost contact state, the roller 400 may deviate from the moving region between the guide portions 450 and the structural stability may be deteriorated. Unnecessary movement of the high-mass guide pendulum 300 and the main pendulum 350 may cause an impact with the penetration portion 240 or noise may be generated.

The roller 400 is moved in the radial direction of the pendulum disk 200 with respect to the guide pendulum 300 as a space between the inner end 304 of the guide pendulum 300 and the opposed portion 244 thereof The structural stability of the guide pendulum 300 can be improved by providing the elastic support portion 470 that pushes the guide pendulum 300 away from the central axis in a space formed on the opposite side of the space where the guide pendulum 300 is located.

In the vibration absorption damper 100 of the vehicle according to the embodiment of the present invention, the diameter of the roller 400 is adjusted by the guide formed in the guide pendulum 300 and the penetrating portion 240, respectively, The distance between the guide portions 450 may be greater than the shortest distance among the guide portions 450 in a state where the distance between the guide portions 450 is maximally increased.

Specifically, when the roller 400 is not positioned between the guide portions 450, there is a fear that the guide pendulum 300 can not return to the correct position and the function of the damper is lost. So that it is prevented from escaping to the outside of the guide portion 450.

The guide pendulum 300 is moved away from the center of rotation by centrifugal force but in a stationary state or at a low rotational speed the distance between the outer end 302 of the guide pendulum 300 and the facing penetration 242 .

When the distance between the outer end 302 of the guide pendulum 300 and the penetration portion 240 is maximally increased because the centrifugal force does not act on the guide pendulum 300 as the pendulum disk 200 is in a stopped state, If the diameter of the roller 400 is greater than the distance between both ends of the guide part 450 protruded from the center part and the guide part 450 of the penetrating part 240, And the like.

That is, when the centrifugal force does not act and the distance between the guide pendulum 300 and the guide part 450 formed in the penetrating part 240 is maximized, the guide part 450, which is the shortest distance among the guide parts 450, The diameter of the roller 400 is made larger than the distance between the protruding end portions of the vibration member 450 and the roller 450. This simplifies and efficiently prevents the roller 400 from being separated from the guide portion 450, 100), it is possible to improve the structural stability.

1 and 2, in the vibration absorption damper 100 of the vehicle according to the embodiment of the present invention, the guide pendulum 300 and the penetration portion 240 are provided in plural, And the center of gravity of the plurality of guide pendules 300 may be aligned with the rotation axis.

Specifically, when the guide pendulum 300 is a high-mass body, the pendulum disk 200 and the pendulum disk 200 are rotated at a high speed. When the guide pendulum 300 and the penetrating portion 240 are provided in plural, If this is not done, a biased force is generated in the pendulum disk 200, which poses a risk to the stability and durability of the transmission.

Accordingly, the guide pendulum 300 has a plurality of guide pendules 300, and the guide pendulum 300 is geometrically symmetric about the rotation axis so that a biased force by the guide pendulum 300 does not act on the transmission input shaft. The mass of the guide pendulum 300 is increased while maintaining the structural stability of the transmission input shaft, thereby effectively improving the vibration absorbing effect.

1 to 3, in the vibration absorption damper 100 of the vehicle according to the embodiment of the present invention, the length of the guide pendulum 300 with respect to the circumferential direction of the pendulum disk 200 is longer than the length of the through- And the length of the guide pendulum 300 may be shorter than the length of the through-hole with respect to the radial direction of the pendulum disk 200. [

Specifically, the guide pendulum 300 should be provided to allow free movement of the pendulum disk 200 in the radial direction and the circumferential direction of the pendulum disk 200 in the penetration portion 240 of the pendulum disk 200, Should be smaller than the cross-sectional area of the penetrating portion 240.

Preferably, the length of the guide pendulum 300 may be shorter than the length of the through-hole, based on the circumferential direction of the pendulum disk 200, The length of the through-hole 300 may be shorter than the length of the through-hole.

While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims It will be apparent to those of ordinary skill in the art.
