Abstract
A sound absorption and isolation module is configured to reduce noise radiated from a tire and an operation apparatus thereof. The sound absorption and isolation module is formed by integrally combining a box outer plate, a sound isolation sheet, a sound absorption material, and a pad member. The sound absorption and isolation module is used to reduce the noise radiated from the tire and generated during a roll-and-brake process.
Claims15
A sound absorption and isolation module configured to reduce noise radiated from a tire, the sound absorption and isolation module comprising:
- a box outer plate configured to form an outer shape of the sound absorption and isolation module and form a skeleton of the sound absorption and isolation module;
- a sound isolation sheet coupled to an inner surface of the box outer plate;
- and
- a sound absorption material coupled to an inner surface of the sound isolation sheet.
An operation apparatus of a sound absorption and isolation module configured to reduce noise radiated from a tire, the operation apparatus comprising:
- a cylinder module connected to the sound absorption and isolation module and configured to move, during operation of the cylinder module, the sound absorption and isolation module toward a side surface of a vehicle entering a roll-and-brake process;
- a base having the cylinder module coupled to the base;
- a guide coupled to the base and formed to extend in a forward-and-rearward direction of the vehicle so as to guide movement of the base;
- and
- a motor configured to provide power for the movement of the base.
