The invention discloses an automobile composite wheel cover with sound absorption performance and rigidity performance, relates to the technical field of wheel trim covers, and aims to solve the problems that the shape of an existing wheel trim cover is fixed, when the wheel trim cover is of a plane closed structure, outward transmission of wheel noise is reduced, but the heat dissipation effect of a brake pad is affected, and the service life of the wheel trim cover is prolonged. And when the wheel decoration cover is of a ventilation structure, heat dissipation can be conducted on the brake pad through air flowing during running, however, when a vehicle runs at a high speed, the wind resistance of the wheel can be increased, and the air flowing noise during running is increased. A wheel trim cover body is installed above the hub, an outer positioning ring is arranged at the outer end of the wheel trim cover body, an inner positioning block is arranged at the inner end of the wheel trim cover body, six fixing rods are annularly arranged between the outer positioning ring and the inner positioning block, and grating plate grooves are formed between the adjacent fixing rods. Three grating plates are distributed in the grating plate groove in a fan-shaped mode.
本发明公开了一种具有吸音性能和刚性性能的汽车复合型轮罩,涉及车轮装饰罩技术领域,为解决现有的车轮装饰罩的形态是固定的,当车轮装饰罩为平面封闭结构时,降低车轮噪声向外的传播,但是其会影响刹车片的散热效果,当车轮装饰罩为通风结构时,可在行驶时通过空气的流动对刹车片进行散热,但是车辆高速行驶时会增加车轮的风阻,增加行驶时的空气流动噪音的问题。所述轮毂的上方安装有车轮装饰罩本体,所述车轮装饰罩本体的外端设置有外定位环,所述车轮装饰罩本体的内端设置有内定位块,所述外定位环与内定位块之间环形设置有六个固定杆,相邻所述固定杆之间设置有格栅板槽,所述格栅板槽的内部扇形分布有三个格栅板。
