The present invention relates to a damper device for a vehicle drive shaft, and more particularly, to a damper device for a vehicle drive shaft that solves the anti-resonance phenomenon by forming an orifice in the existing damper device to discharge the air.

In general, the drive shaft of the vehicle serves to transmit the rotational driving force of the transmission to the drive wheel side.

The drive shaft of the vehicle has a structure in which two constant velocity joints are connected between the differential gear of the transmission gear and the wheel hub of the driving wheel, respectively.

When the vibration frequency of the conventional engine and the rotation speed of the drive shaft coincide with each other, noise is generated due to resonance, and a damper is mounted to the drive shaft to prevent this.

The damper of the drive shaft according to the prior art is composed of a damper housing and one mass (mass) that is formed integrally with the damper housing to reduce resonance.

The resonance phenomenon can be prevented by changing the mass of the target object. When the drive shaft causes resonance with the drive system, a damper with mass (mass) is mounted to dualize the generated resonance frequency to prevent resonance to reduce vibration. Can be.

However, in the conventional technology as described above, the damper of the general rubber material has a low attenuation value, thereby causing anti-resonance phenomenon, and thus, two dampers are installed, resulting in a cost increase.

In addition, since the material of the damper changes with temperature, the lower the temperature, the more the damper is hardened and the resonant frequency increases.If the resonant frequency is set to a high temperature condition, the frequency is inconsistent with a low temperature condition, resulting in an NVH phenomenon such as a booming. There is a problem.

The damper device of a vehicle drive shaft according to an embodiment of the present invention forms an orifice in the damper housing and a mass body integrally mounted inside the damper housing, so that air filled in an enclosed space between the drive shaft and the damper housing passes through the orifice.

In the damper device of a vehicle drive shaft according to an embodiment of the present invention, the damper device of the vehicle drive shaft for mounting on the drive shaft of the vehicle to absorb vibration, and the elastic member is mounted on the outer peripheral surface of the drive shaft in the circumferential direction; A banding member mounted at both ends of the elastic member to fix the elastic member, a mass body mounted along the circumferential direction on the inner circumferential surface of the elastic member, and an orifice penetrating the elastic member and the mass body on the outer circumferential surface of the drive shaft; It may include a pipeline.

In the damper device of the vehicle drive shaft, a sealed space in which air is filled in the longitudinal direction is formed between the drive shaft and the elastic member, the sealed space may be connected to the orifice pipe.

In the damper device of the vehicle drive shaft, the mass is moved in the vertical direction when the resonance of the elastic member occurs, it is possible to discharge the air filled in the sealed space to the outside through the orifice pipe.

The damper device of a vehicle drive shaft according to an embodiment of the present invention forms an orifice pipe in an elastic member and a mass body integrally mounted inside the elastic member so that air filled in an enclosed space between the drive shaft and the elastic member is connected to the orifice pipe. By being discharged through, it is possible to prevent the anti-resonance phenomenon of the damper device of the vehicle drive shaft.

In addition, by reducing the number of damper devices mounted on the drive shaft, the components of the elastic member and the bending member may be reduced, thereby reducing the cost.
