Abstract
A vibration absorber for vehicle wheels is capable of absorbing and attenuating vibration of a vehicle wheel and of increasing a vibration absorption capability of the wheel without changing the external appearance and design of the wheel. The vibration absorber includes a vibration absorption unit mounted on a back surface of a center cap of the vehicle wheel to absorb a first vibration in an axial direction of the wheel transmitted through the center cap.
Claims6
A vibration absorber for vehicle wheels, the vibration absorber comprising:
- a center cap configured to open and close an opening provided at a center of a wheel;
- and
- a vibration absorption unit mounted on a back surface of the center cap to absorb a first vibration in an axial direction of the wheel transmitted through the center cap,
- wherein the vibration absorption unit includes
- a housing mounted on the back surface of the center cap,
- a mass body disposed in an internal space of the housing to vibrate in the axial direction of the wheel by the first vibration transmitted through the center cap, and
- an elastic support disposed in the internal space of the housing to support the mass body such that the mass body is able to vibrate in the axial direction of the wheel,
- wherein the internal space of the housing is divided into a first space and a second space by the mass body, and
- wherein the elastic support comprises an outer spring disposed in the first space, both ends thereof being mounted to the mass body and the housing, and an inner spring disposed in the second space, both ends thereof being mounted to the mass body and the housing.
