The invention discloses a wheel hub with good heat dissipation performance. The wheel hub comprises a wheel hub main body and a heat dissipation device for dissipating heat of a brake disc, a plurality of heat dissipation openings are formed in the wheel hub body, and the heat dissipation device comprises a plurality of heat dissipation components corresponding to the heat dissipation openings. Each heat dissipation component comprises an air holding plate for holding and moving air into the heat dissipation opening, and an inertia plate for correspondingly sealing the heat dissipation openingand driving the air holding plate to be opened or closed; a containing cavity capable of containing the heat dissipation components and allowing the heat dissipation components to slide is formed inthe wheel hub body. When a vehicle drives, the inertia plates of the heat dissipation components just seal the heat dissipation openings to prevent airflows from entering a wheel hub, the wind resistance is reduced, and the oil consumption is reduced; when the brake decelerates, due to inertia, the inertia plates rotate to receding areas, a connecting frame and the air holding plates rotate to a ventilation area, the air holding plates are popped up at the moment, the heat dissipation openings are opened, at the moment, the air holding plates can catch airflows into the wheel hub to cool the brake disc, so that a problem that the brake disc cannot dissipate heat in time is solved.

    本发明公开一种散热性好的车轮毂,包括车轮毂主体和对刹车盘进行散热的散热装置;所述车轮毂主体上设有多个散热口,所述散热装置包括多个与所述散热口相对应的散热部件;所述散热部件包括将空气兜进散热口的兜风板,以及对应封盖散热口并驱动兜风板开合的惯性板;所述车轮毂主体内具有能够容纳散热部件并供散热部件滑动的容纳腔。当汽车在行驶时,散热部件的惯性板刚好将散热口封闭起来,防止气流进入车轮毂,可以减小风阻,降低油耗,当刹车减速时,由于惯性,惯性板转动到让位区,连接架与兜风板转动到通风区,这时兜风板被弹出,使散热口打开,此时,兜风板就可以将气流兜进车轮毂,对刹车盘进行冷却散热,解决了刹车盘不能及时散热的问题。
