In addition, in the conventional torque converter, when the frequency of the rotational power of the engine input to the front cover coincides with the natural frequency of the torque converter, resonance occurs. The amplitude of the frequency of the driving force input to the input shaft of the transmission through the torque converter can be increased. If the amplitude of the vibration frequency of the driving force input to the transmission input shaft increases, the performance of the vehicle's NVH (Noise, Vibration, Harshness) deteriorates, the fuel consumption decreases, and the power transmission performance of the torque converter deteriorates.

That is, the driving force of the drive plate 22 can be transmitted to the first and second cover plates 26 and 28 through the first spring 24. In this process, the first spring 24 can absorb vibrations and shocks in the rotational direction.

In this embodiment, the second spring 32 is supported by the first and second cover plates 26, 28 and is disposed in a circumferential direction. Here, the second spring 32 may be disposed on the inner circumferential side of the first spring 24 about the rotation axis.

The second spring 32 is elastically supported by the driven plate 34. That is, the driving force transmitted to the first and second cover plates 26 and 28 is transmitted to the driven plate 34 through the second spring 32. In this process, the second spring 32 can absorb vibration and shock in the rotating direction again.

And the driven plate 34 is connected to the spline hub 36. The spline hub 36 may transmit the driving force of the engine to the transmission.

Here, the turbine assembly 6 may be axially coupled to the spline hub 26, as shown in FIGS. 3-5.

In this embodiment, the mounting portion 42 protrudes from the support portion 38 toward the turbine assembly 6 in a cylindrical shape, and is inserted into the mounting hole 8a.

The fitting groove 44 is formed around the outer peripheral surface of the mounting portion 42 corresponding to the locking projection 8b.

Here, the fitting grooves 44 may be formed at equal intervals along the circumference of the mounting portion 42. That is, the fitting grooves 44 may be formed in a gear tooth shape along the circumference of the mounting portion 42 so that the locking protrusions 8b are engaged with each other.

Accordingly, the turbine plate 8 can transmit the rotational force to the spline hub 36 in a stable manner.

Meanwhile, the turbine plate 8 is inserted into the fitting portion 42 through the fitting hole 8a while the locking protrusion 8b is inserted into the fitting groove 44, To the spline hub 36 by means of a snap ring 48 mounted on the spline hub 36.

The pendulum assembly 38 is configured such that the pendulum 44 moving in the radial direction by the centrifugal force is arranged to act as a mass to absorb vibration and shock in the rotational direction. The vibration generated in the turbine assembly 6 can be more efficiently attenuated together with the local dampers 20. [

The pendulum assembly 50 according to the embodiment of the present invention will now be described in detail with reference to FIGS. 6 and 7. FIG.

6 and 7 are a perspective view and an exploded perspective view of a pendulum assembly applied to a torque converter for a vehicle according to an embodiment of the present invention.

Referring to FIGS. 6 and 7, the pendulum assembly 50 may include a support plate 52, a plurality of pendulums 54, and a plurality of engagement pins 56.

First, the support plate 52 may be riveted to the second cover plate 28. The support plate 52 is provided with a plurality of slots 52a. The slots 52a of the support plate 52 may be rounded.

The pendulum 54 is also provided with a plurality of slots 54a. The slot 54a formed in the pendulum 54 may be rounded and may be formed in a round shape opposite to the slot 52a provided in the support plate 52. [

The coupling pins 56 are inserted into the slots 52a and 54a to couple the support plate 52 and the pendulum 54 together. These slots 52a and 54a allow the pendulum 54 coupled to the engaging pin 56 to move along a constant trajectory by centrifugal force.

The operation of the embodiment of the present invention will be described as follows.

First, when the lockup clutch 14 is not operated, the driving force of the engine is transmitted to the front cover 2, the impeller 4, the turbine assembly 6, the first and second cover plates 26 and 28 , The second spring 32, the driven plate 34, and the spline hub 36 to the transmission. In this process, the second spring 32 can absorb vibration and shock in the rotating direction.

On the other hand, when the lockup clutch 14 is operated, the piston 16 is moved toward the front cover 2 by the hydraulic pressure.

The frictional members 19 provided on both sides of the friction plate 18 are in close contact with the inside of the front cover 2 and one side of the piston 16 so that the driving force of the front cover 4 is transmitted to the friction plate 18).

And the driving force transmitted to the friction plate 18 is transmitted to the drive plate 22. The drive plate 22 transmits the driving force to the first and second cover plates 26 and 28 while compressing the first spring 24.

In this process, the first spring 24 absorbs vibrations and shocks in the rotating direction with respect to the center of rotation.

Subsequently, the first and second cover plates (26, 28) compress the second spring (32). As a result, the second spring 32 is compressed and transmits driving force to the driven plate 34. In this process, the second spring 32 absorbs vibrations and shocks in the rotational direction with respect to the center of rotation.

The driving force transmitted to the driven plate 34 is transmitted to the transmission through the spline hub 36.

In this process, the pendulum 54 provided in the pendulum assembly 50 absorbs vibrations and shocks by moving in the circumferential direction or along the locus designed by the designer with respect to the center of rotation by the centrifugal force.

That is, when the engine is driven, the pendulum 54 provided in the pendulum assembly 50 is moved by the centrifugal force, so that the number of revolutions of the engine can be operated irrespective of the low speed or the high speed state to absorb vibration and impact.

In addition, the present invention can more reliably transmit the rotational driving force of the turbine assembly 6 to the spline hub 36 by connecting the turbine assembly 6 to the spline hub 36 in the axial direction.

At the same time, the present invention effectively dampens the vibration of the turbine assembly 6 through the local damper 20 connected to the spline hub 36 and the pendulum assembly 50, It is possible to avoid the resonance occurrence area of the resonator.

Therefore, by applying the torque converter for a vehicle according to the embodiment of the present invention configured as described above, the mounting position of the turbine plate 8 connected to the turbine blades 10 is changed to avoid the resonance generation region, Up clutch 14 can be operated while attenuating the vibration sufficiently in all of the revolving speed range of the engine 1, thereby improving the vibration insulation characteristic.

By coupling the pendulum assembly 50 provided with the pendulum 54 to the local damper 20, the pendulum 54 is continuously operated even in the high-speed and low-speed rpm regions of the engine, Up clutch 14 can be operated even in the low-speed rotation speed range of the engine so that the fuel consumption of the vehicle can be improved.

In addition, by changing the mounting position of the turbine assembly 6 and using the natural frequency of the pendulum assembly 50, the input exciter is canceled to isolate the vibration, thereby improving the overall NVH performance of the vehicle, The power transmission performance can be improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be understood that various modifications and variations may be made without departing from the scope of the appended claims.
