<p>The present invention relates to a dynamic damper for a constant velocity joint, capable of reducing noise and vibration of a vehicle due to changes in environmental conditions and enhancing the comfort of a driver and a passenger by minimizing changes in the natural frequency of the dynamic damper changing in accordance with the external temperature and allowing unique features of the dynamic damper to be maintained. In addition, the present invention prevents loosening and unfastening as a change in the fastening force due to the external temperature is minimized by inserting a fixing band into a body. The dynamic damper for the constant velocity joint comprises: a first body and a second body mounted in a shaft; a polymer connecting the first and second bodies; a proof mass fixedly installed inside the polymer; a variable bridge mounted in the proof mass to be able to change the position; and a fixing band to fixedly mount the body on the shaft.</p> |
