Device reducing automobile windage

Abstract

The invention provides a device which reduces the wind resistance of an automobile. A conical bag in streamline appearance is arranged at the tail of the body of the original automobile; the conical bag is connected with the tail of the automobile body, is filled with the air and can be removed when necessary; furthermore, the conical bag can be deflated and contracted to be tightly attached to the body. The invention is connected with the tail of the automobile; the streamline appearance of the conical bag leads the airflow at the tail of the automobile which is driven in high-speed to be well dredged, and the air pressure difference between the head and the tail of the automobile is reduced, thus implementing the object of wind resistance reduction; furthermore, the invention has the advantages of simple structure, convenient disassembly and assembly and contraction, therefore reaching energy-saving and exhaust reduction.

Description

technical field [0001] The invention relates to the technical field of motor vehicles, in particular to a streamlined body structure. Background technique [0002] The energy consumption of the vehicle is mainly used to overcome resistance. The greatest resistance in high-speed driving comes from air resistance. The functional consumption caused by wind resistance accounts for more than 60% of the total energy consumption, while the appearance wind resistance accounts for about 60% of the total wind resistance. , so people are constantly improving the shape of the car to reduce wind resistance; while the shape design has always focused on the shape of the windward side, and the formation of wind resistance also includes the negative pressure area at the rear of the body, which is often ignored; especially large For passenger cars, trucks, container trucks, box cars, etc., the tail of the body is generally in the shape of a facade, so that the wind resistance caused by the ne...
