Low-wind-resistance wheel and automobile

Abstract

The low-wind-resistance wheel comprises a rim, spokes and a hub, the spokes are evenly distributed between the rim and the hub, the hub is provided with an energy storage bag, each spoke is provided with a guide pipe, one end of each guide pipe communicates with the energy storage bag, each guide pipe is connected with a sliding assembly, and the sliding assemblies are connected with the spokes. And the extrusion mechanism pushes the medium in the energy storage bag to enable each sliding assembly to slide, and drives the end part of each curtain connected to the sliding assembly to move so as to change the ventilation opening of the wheel. The automobile comprises the low-wind-resistance wheel. The automobile energy-saving device has the beneficial effects that the energy storage bag is arranged on the hub, the sliding assembly is arranged on the guide pipe, the extrusion mechanism is arranged on one side of the energy storage bag, thrust formed by media in the energy storage bag is controlled through the extrusion mechanism, the curtain unfolding size of the sliding assembly is controlled, the ventilation opening is closed through the curtain, and oil consumption generated by wind resistance of an automobile is reduced; and meanwhile, the heat dissipation requirement of wheel accessories such as brake pads during emergency braking is met.

Description

technical field [0001] The invention relates to the structure of auto parts, in particular to a low wind resistance wheel and an automobile. Background technique [0002] With the stringent requirements of automobile regulations on fuel consumption and emissions and the pursuit of battery life in the electric vehicle market, vehicle manufacturers have listed reducing vehicle wind resistance as a key technical research topic. Reducing the wind resistance of automobiles has a significant effect on reducing fuel consumption and increasing the mileage of electric vehicles, and the work of reducing the wind resistance of the whole vehicle is subdivided into various components, and the work of reducing the wind resistance of wheels is of great significance. [0003] Due to the heat dissipation requirements of rims, brake calipers, friction plates, brake discs and other components, the ability of low-drag wheels to reduce wind resistance is greatly limited. The existing low-drag wh...

Problems solved by technology

[0004] The purpose of the present invention is that the air vents cannot be adjusted in the existing low-drag wheel structure. In order to achieve the effect of heat dissipation, a smaller air vent is provided. The heat dissipation of the brake pads has no obvious effect on reducing fuel consumption. A low-drag wheel is provided to solve the above problems
