The invention discloses a closable type wheel hub system. The closable type wheel hub system comprises a wheel hub and a wheel hub closing mechanism. The wheel hub is provided with a hollow area. The wheel hub closing mechanism is arranged on the wheel hub and is suitable for closing at least part of the hollow area. The wheel hub closing mechanism comprises a separation blade suitable for closing at least part of the hollow area and a reset mechanism suitable for moving the separation blade from the hollow area to the original position. The wheel hub closing mechanism moves the separation blade to the hollow area with the help of the centrifugal force during rotation of the wheel hub. The invention further discloses a corresponding wheel and a corresponding vehicle. The wheel hub system can reduce the aerodynamic resistance when the vehicle runs at a high speed, so that the wind resistance can be reduced, the high-speed energy consumption of the vehicle is reduced, and the stability of high-speed running of the vehicle is improved.
