Embodiment Construction

[0038] According to an embodiment of the present invention combined with Figure 4 with Figure 5 It can be seen that the active opening and closing hub structure 100 includes: a fixed spoke 1, in which there are a plurality of gaps 11; a cover plate 2, which is arranged on the fixed spoke 1, and in the cover plate 2 There are a plurality of matching gaps 21 and shielding parts 22 matching the gaps 11, and the cover plate 2 can rotate relative to the fixed spoke 1 to switch between an open state and a closed state. The open state refers to the cover The mating gap 21 of the plate 2 overlaps the gap 11 of the fixed spoke 1, and the closed state means that the shielding part 22 of the cover plate 2 overlaps the gap 11 of the fixed spoke 1; when the vehicle speed is lower than the first speed, it is in the In the open state, the gap 11 is fully open (refer to figure 1 ), at this time, the hub is still in the conventional hub shape from the appearance; when the vehicle speed is ...

Abstract

The invention discloses an active opening and closing hub structure and car. The active opening and closing hub structure comprises a fixed spoke in which a plurality of gaps exist; a cover plate arranged on the fixed spokes, in which there are a plurality of mating gaps and shields matched to the gaps, the cover plate being rotatable relative to the fixed spokes so as to switch between an open state and a closed state; the open state refers to the overlap between the mating clearance of the cover plate and the clearance of the fixed spokes, and the closed state refers to the overlap between the shielding part of the cover plate and the clearance of the fixed spokes. When the vehicle speed is less than the first speed, being in an open state; when the vehicle speed is greater than the second speed, it is in the closed state. The hub structure can be switched between an open state and a closed state by providing a cover plate capable of rotating relative to a fixed spoke. When the brakeis in the open state at low speed, the heat dissipation of the brake is enhanced; at high speed, it is in the closed state, which reduces the wind resistance of the automobile.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an actively openable and closed hub structure and a vehicle with such an actively opened and closed hub structure. Background technique [0002] Wheel hub (Wheel hub), also known as rim, steel ring, and wheel, is a metal part that supports the tire inside the tire. There are many classifications of wheels according to size, material, and function. At the same time, as an important design highlight and selling point of the appearance part, in the design of modern cars, designers have begun to pay more and more attention to the shape design and functional design (heat dissipation, noise reduction, etc.) of the wheel hub. aspects are rarely involved. [0003] Automobile aerodynamics is an important branch of aerodynamics, which studies the interaction between the car and the surrounding air during relative motion. Tests have proved that with the increase of vehicle speed, the proportio...
