Description

Technical Field

[0001] This invention relates to a system for reducing or increasing air resistance in vehicles, which will be applied in the automotive industry and transportation technology, particularly for the installation of ducts and turbines in vehicles to reduce air resistance. Background Technology

[0002] Reducing vehicle drag is a key aspect of improving vehicle efficiency and energy performance. High drag leads to increased fuel consumption, or increased energy consumption in electric vehicles. Various strategies are known to reduce drag, such as: designing the front and rear of the vehicle to avoid sharp edges and integrating aerodynamic components to reduce turbulence; using deflectors and various aerodynamic accessories to create smooth surfaces and reduce drag; using adjustable aerodynamic components, such as movable spoilers that adjust according to speed and road conditions; and improving the underside of the vehicle, such as by placing motors and using a flat floor.

[0003] Patent document RU2651951C1 discloses an element for improving the aerodynamics of a vehicle's engine compartment, which is a duct fixed horizontally, vertically, or diagonally under the vehicle's hood. It can be located not only in front of the engine but also in front of the rear wall of the engine compartment and / or other components, and is shaped to direct airflow to areas with lower air resistance.

[0004] Patent application US2008309121A1 discloses a system for reducing aerodynamic drag on a vehicle. The system includes a series of struts placed on the sides of the truck body, which are covered by a second roof. This forms a duct system that captures airflow at the front of the van and directs it to the rear of the van, where a similar set of ducts delivers the airflow downwards to the rear of the truck. Summary of the Invention

[0005] The purpose of this invention is to provide a system for reducing or increasing vehicle air resistance, which simultaneously reduces frontal aerodynamic drag, increases vehicle downforce and vehicle stability during driving, and improves vehicle braking and control by optimizing airflow.

[0006] This problem is solved by creating a system that reduces or increases vehicle aerodynamic drag, including ducts for capturing airflow in front of the vehicle. According to the invention, the system includes: a central air duct, centrally positioned along the entire length of the vehicle and mechanically clamped to the chassis; and two front side air ducts, respectively located at the two foremost points of the vehicle and extending to a section downstream of the front wheels. Two additional branches are formed at the rear end of the central duct, representing two rear side ducts. Two bidirectional turbines are fitted at each end of the central duct, and one bidirectional turbine is fitted within each side duct. A front central grille is fitted at the front opening of the central duct, and a rear central grille is fitted at the rear opening of the central duct. The side ducts have front side grilles mounted in the front openings and side grilles mounted in the rear openings. Additional rear grilles or injectors are mounted in the rear openings of the two rear side ducts. All grilles are fitted with multiple sets of guide vanes, providing both lateral and vertical guidance. The system includes a control module for controlling the bidirectional turbines, the multiple sets of guide vanes, and reinforcing ribs located on both sides of the central duct and inside the two front side ducts.

[0007] All air duct openings and all grilles are rectangular, circular, oval, or irregular in shape.

[0008] The bidirectional turbine is multi-stage and equipped with disc brakes, electric brakes or other types of brakes.

[0009] The advantage of this system is that it can reduce frontal drag by optimizing airflow. Furthermore, the invention can also be used as a brake to reverse the direction of the turbine, thereby increasing air resistance on the vehicle surface. Attached Figure Description

[0010] In the appendix Figure 1 The invention is illustrated in the appendix. Figure 1 This is a schematic diagram of the vehicle air resistance reduction system according to the present invention. Detailed Implementation

[0011] A system designed to reduce or increase vehicle aerodynamic drag includes: a central air duct 1, centrally positioned along the entire length of the vehicle and mechanically clamped to the chassis; and two front side air ducts 2, located at the two foremost points of the vehicle and extending to a section downstream of the front wheels. Two additional branches are formed at the rear end of the central air duct 1, forming two rear side air ducts 4. Two bidirectional turbines 3 are mounted at each end of the central duct 1, and one bidirectional turbine 3 is mounted within each of the side ducts 2 and 4. A front central grille 1.1 is mounted at the front opening of the central duct 1, and a rear central grille 1.2 is mounted at the rear opening of the central duct. Front side grilles 2.1 are mounted in the front openings of the side air ducts 2, and side grilles 2.2 are mounted in the rear openings of the side air ducts. Other rear grilles 4.1 are fitted into the rear openings of the two rear side air ducts 4. Grilles 1.1, 1.2, 2.1, 2.2, and 4.1 are each provided with multiple sets of guide vanes 5, providing both left-right and up-down guiding functions. The system includes a control module 6 for controlling the bidirectional turbine 3 and multiple sets of guide vanes 5. The system also includes reinforcing ribs 7 located on either side of the central duct 1 and inside the two front ducts 2. The reinforcing ribs 7 are made of metal sheets with a thickness ranging from 0.8 mm to 5 mm.

[0012] The openings of conduits 1, 2 and 4, as well as all grids 1.1, 1.2, 2.1, 2.2 and 4.1, should be rectangular, circular, elliptical or irregular in shape, respectively.

[0013] The bidirectional turbine 3 is multi-stage and is equipped with disc brakes, electric brakes or other types of brakes.

[0014] The essence of this invention lies in reducing air resistance by removing as much air as possible from the oncoming airflow area and the space between the vehicle's undercarriage and the road surface, in a manner proportional to vehicle speed. To this end, ducts 1, 2, and 4 are equipped with turbines 3 that further "pull" the oncoming airflow and guide it away from the rear of the vehicle. For example, to reduce air resistance during driving, turbines 3 will engage when a preset speed (above 55 km / h) or other programmable value is reached. When the accelerator pedal pressure is released, or any other type of forward command is given, turbines 3 will cease operation.

[0015] This invention can also function as a brake, reversing the direction of the turbines 3 and thus increasing the vehicle's frontal air resistance. When the vehicle's brake pedal is depressed, all turbines 3 will be driven in the opposite direction to generate additional air resistance and assist the vehicle in braking.

[0016] The designed system can also be used for assisted directional control, i.e., using only a portion of the orifice and utilizing the directional airflow that generates resistance. This is achieved by controlling the speed of the turbine 3 and by using multiple sets of guide vanes 5 mounted in all the grilles 1.1, 1.2, 2.1, 2.2, and 4.1. The control module 6 controls the direction and speed of the turbine 3, as well as the left-right and up-down movement of the multiple sets of guide vanes 5, according to the requirements and commands of the vehicle pedals, electronic stability program, and steering wheel, so that there is a synergistic effect between these turbines and these guide vanes, and the speed of each turbine is increased or decreased individually according to the received commands.

[0017] For example, when turning right and after a quarter turn or other programmable amount of steering wheel rotation, the turbine 3 in the left front duct 2 and the turbine 3 in the right rear duct 4 will stop operating. Similarly, when turning left, the opposed turbine 3 in the right front duct 2 and the left rear duct 4 will stop operating.
