Description

Technology Field

[0001] The present invention relates to a system for reducing or increasing air resistance of a vehicle applicable to the automotive industry and transportation technology, and in particular to a system for implementing tubes and turbines in a vehicle to reduce air resistance. Background Technology

[0002] Reducing vehicle air resistance is a key aspect of efforts to improve vehicle efficiency and energy performance. High air resistance can increase fuel consumption and, in the case of electric vehicles, energy consumption. Different strategies are known to reduce air resistance, such as the following: designing the front and rear ends of the vehicle by incorporating aerodynamic elements to avoid sharp edges and reduce turbulence; wind deflectors and various aerodynamic accessories that can create smooth surfaces and help reduce air resistance; the use of adjustable aerodynamic elements, such as movable spoilers that can be adjusted according to speed and road conditions; and improvements to the vehicle undercarriage, such as motor placement and the use of a flat floor.

[0003] Patent document RU2651951C1 discloses an element for improving the aerodynamics of the engine room of a vehicle, which is a type of duct fixed horizontally, vertically, or diagonally under the bonnet of the vehicle. This element may be located in front of the engine as well as in front of the rear wall and / or other parts of the engine room, and is shaped to guide airflow to an area of ​​low air resistance.

[0004] Patent application US2008309121A1 discloses a system for reducing aerodynamic drag of a vehicle. The system comprises a series of struts positioned on the upper side of a truck body, which are covered by an auxiliary roof. By this, a duct system is formed that captures airflow at the front end of the van and directs it toward the rear of the van, where a similar set of ducts transmits the airflow under the rear of the truck.

[0005] The objective of the present invention is to provide a system for reducing or increasing the air resistance of a vehicle, which provides a reduction in forward aerodynamic air resistance by optimizing airflow, an increase in vehicle stabilization and vehicle downforce during driving, and an improvement in vehicle braking and control.

[0006] The above problem is solved by devising a system for reducing or increasing vehicle air resistance, comprising a duct for capturing airflow at the front of the vehicle. According to the present invention, the system comprises a central air duct located centrally along the entire length of the vehicle and mechanically clamped to the chassis, and two front side air ducts located at each of the outermost ends on both sides of the front of the vehicle to the downstream section of the front wheels. At the rear end of the central duct, two additional branches are formed to represent two rear side ducts. Two bidirectional turbines are installed at each end of the central duct, and one bidirectional turbine is installed in each side duct. A front central grille is installed at the front opening of the central duct, and a rear central grille is installed at the rear opening. The side ducts have a front side grille mounted at the front opening and a side grille mounted at the rear opening. Another rear grille or injector is mounted at the rear opening of the two rear side ducts. All grilles are equipped with a set of slats having left or right and upward or downward guiding functions. This system includes a control module for controlling a bidirectional turbine and a set of slats, and reinforcing members located on both sides of the central duct and on the inside of two front side ducts.

[0007] All air duct openings and all grilles each have a rectangular, circular, oval, or irregular shape.

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

[0009] The advantage of this system is that it can reduce forward resistance by optimizing airflow. In addition, the present invention can also be used as a brake by reversing the direction of the turbine and increasing air resistance at the front of the vehicle. Brief explanation of the drawing

[0010] The present invention is illustrated in the attached FIG. 1, which is a schematic diagram illustrating the principle of a vehicle air resistance reduction system according to the present invention. Specific details for implementing the invention

[0011] A system designed to reduce or increase the air resistance of a vehicle includes a central air duct (1) located centrally along the entire length of the vehicle and mechanically clamped to the chassis, and two front side air ducts (2) located from each of the two foremost ends of the vehicle to the downstream section of the front wheels. At the rear end of the central air duct (1), two additional branches are formed to form two rear side air ducts (4). Two bidirectional turbines (3) are installed at each end of the central duct (1), and one bidirectional turbine (3) is installed at each of the side ducts (2, 4). In the central duct (1), a front central grille (1.1) is mounted at the front opening, and a rear central grille (1.2) is mounted at the rear opening. In the side air ducts (2), a front side grille (2.1) is mounted at the front opening, and a side grille (2.2) is mounted at the rear opening. Another rear grille (4.1) is installed at the rear opening of the two rear side air ducts (4). All grilles (1.1, 1.2, 2.1, 2.2, 4.1) are provided with a set of slats (5) having left or right and upward or downward guiding functions. The system includes a control module (6) for controlling the bidirectional turbine (3) and the set of slats (5). The system also includes reinforcing members (7) located on both sides of the central duct (1) and on the inside of the two front side ducts (2). The reinforcing members (7) are composed of metal sheets having a thickness of 0.8 to 5 mm.

[0012] The openings of the ducts (1, 2, 4) and all the grills (1.1, 1.2, 2.1, 2.2, 4.1) each have a rectangular, circular, elliptical, or irregular shape.

[0013] The bidirectional turbine (3) is multi-stage and is equipped with a disc brake, an electric brake, or other types of brake.

[0014] The core of the present invention is to remove as much air as possible in proportion to the speed of the vehicle from the airflow area entering the road vehicle and the space between the underside of the vehicle and the road surface in order to reduce air drag. For this purpose, a turbine (3) is installed within the duct (1, 2, 4), and the turbine (3) further ‘draws’ the incoming airflow and directs it away from the rear end of the vehicle. For example, to reduce air resistance while driving, the turbine (3) operates when a preset speed (over 55 km / h) or other programmable value is reached. When the accelerator pedal pressure is removed or any other type of forward command is given, the turbine (3) stops operating.

[0015] The present invention can also serve as a brake by reversing the direction of the turbines (3) and increasing the forward air resistance of the vehicle. When the vehicle's brake pedal is pressed, all turbines (3) are driven in the opposite direction to generate additional air resistance and assist in braking the vehicle.

[0016] The designed system can also be used to assist directional control by using only a portion of the orifice with a directional air stream that generates resistance. This is achieved by controlling the speed of the turbine (3) and using the slat set (5) installed in all grilles (1.1, 1.2, 2.1, 2.2, 4.1). The control module (6) controls the direction and speed of the turbine (3) and the movement of the slat set (5) to the left or right and upward or downward as commanded and required by the vehicle pedals, electronic stabilization program, and steering wheel, and accordingly, there is a synergistic effect between them, and the speed of each turbine is individually increased or decreased according to the received command.

[0017] For example, when turning right, and after a quarter turn or another programmable amount of steering wheel rotation, the turbine (3) in the left front side duct (2) and the turbine (3) in the right rear side duct (4) stop. Similarly, when turning left, the opposite turbine (3) in the right front side duct (2) and the left rear side duct (4) also stop.
