Title:
WHEEL WITH IMPROVED NOISE AND VIBRATION
Document Type and Number:
WIPO Patent Application WO/2019/035510
Kind Code:
A1
Abstract:
The present invention is configured such that a ring-shaped load distribution insert is inserted into an elastic part formed in a disc shape on the basis of the shaft support insert so as to match the center of each of the load distribution inserts with the center of the shaft support insert. Due to this feature, even if a load is applied between the shaft support insert and the elastic part which contacts the ground, the load is distributed evenly throughout the elastic part through the load distribution insert, such that noise and vibration can be reduced and the service life of the wheel can be extended. In particular, in the present invention, a plurality of deformation guide grooves are formed at regular intervals in the radial direction on the basis of the shaft support insert in the elastic part between the shaft support insert and the load distribution insert. Therefore, when a load is distributed through the load distribution insert, the load distribution insert is easily deformed through the plurality of deformation guide grooves, thereby further enhancing a load distribution effect.
