摘要： A sound absorber is configured as a rectangular hexahedral box and forms a porous double-layer Helmholtz resonance sound absorbing structure, at the same time, the sound absorber in the form of a box forms a structural resonance sound absorbing device itself, and the first-order natural mode frequency of the device is identical to that of a wheel air chamber. When the box-type sound absorbing structure is assembled in a wheel, double functions of absorbing acoustic resonance of the wheel air chamber under the organic combination of Helmholtz resonance sound absorption and structural resonance sound absorption can be realized.

摘要： A wheel and a rim with weight reduction sockets are provided. The rim includes an inner flange, a middle portion and an outer flange, the inner flange, middle portion and outer flange are all annular and are connected end to end to form a cylindrical rim, in which the middle portion of the rim includes weight reduction sockets; and the weight reduction sockets are of regular hexagons, and are arranged adjacently on the outer side of the middle portion of the rim in the shape of a honeycomb. The weight of the hub is reduced by designing the weight reduction sockets in a specific shape for the outer rim of the hub and selecting the size of the weight reduction sockets.
