Description

Air resistance reduction device for automobiles {AIR RESISTANCE REDUCING DEVICE OF A VEHICLE}

The present invention relates to an apparatus for reducing air resistance for automobiles, and more particularly, to obtain rotational power by wind power generated as the vehicle travels in order to reduce the air resistance generated in the front part of the vehicle body during driving of the vehicle. Air guides with a fan frame interlocked to the front of the vehicle to induce the flow of air generated on the front of the vehicle as the fan frame rotates to reduce fuel consumption and provide a smooth ride. A resistance reduction device.

When the vehicle is driven, air hits the front of the vehicle, causing air resistance. This phenomenon causes a large amount of energy due to the drag that cannot be ignored, especially during high-speed driving, resulting in increased fuel costs. There was a problem in that the vehicle can not run smoothly and the ride comfort.

In order to solve this problem, the structure of the car body must be improved to minimize air resistance by allowing air to flow in a streamlined form, but it can be applied to future vehicles. The problem was not solved.

In addition, in the case of large trucks and buses, the air resistance applied to the front surface is larger due to the larger size of the vehicle body, but the structural improvement of the vehicle body is more limited than the general passenger vehicle due to the use characteristics of the vehicle. Installing additional devices to reduce air resistance generated on the front side can reduce development costs and economic burden on users.

In addition, as the fly travels with the flow of air as the vehicle moves, the fly fly and the like accumulates foreign matter on the glass of the vehicle, obstructing the driver's field of view, and has to work frequently to remove it. Occurred.

The present invention has been made to solve the problems of the prior art as described above, and is an automotive air resistance reduction device for reducing the air resistance generated in the front when the vehicle is running.

The present invention obtains the rotational power by the flow of air generated as the vehicle travels, that is, wind power, by using a fan frame mounted on the front of the vehicle to distribute the air film formed on the front of the vehicle to induce air The purpose is to reduce the resistance.

In addition, the aim is to reduce fuel consumption and provide a smooth running environment by reducing air resistance.

In addition, it is an object to reduce the phenomenon that foreign matters such as fly flies adhere to the glass of the vehicle as the vehicle travels.

In order to achieve the above object, the present invention is a device for reducing the air resistance generated on the front of the vehicle body when the vehicle is running, a plurality of rotations to be mounted on the vehicle body to generate a rotational power by the flow of air when the vehicle is running The fan is mounted on the same shaft in the longitudinal direction and is mounted on the front of the vehicle body, and the air guide for distributing air generated in the front of the vehicle and the rotation power generated by the rotation power unit are transmitted to the air guide. In order to be characterized in that it comprises a flexible cable mounted between the rotary power unit and the air guide.

In addition, the air guide extends radially from the outer circumferential surface of the hub in the form of a cylindrical tube spaced apart from the drive shaft and the drive shaft and the drive shaft which is linked by a fixed plate for fixing to the front portion of the vehicle body and the flexible cable transmitted to the drive shaft. A plurality of fans are attached to the inner surface of the hub, the fan frame is provided with an auxiliary fan and located in the front of the fan frame is connected by a bearing, the diameter of the tube is gradually narrower toward the front spirally on the outer peripheral surface It is preferably configured to include a diffuser tube having a bent wing.

In addition, the through hole is preferably formed in the hub and the auxiliary fan of the fan frame.

According to the present invention as described above, the present invention obtains the rotational power by the wind power generated as the vehicle travels in order to reduce the resistance due to the flow of air corresponding to the moving direction of the vehicle, using the fan coupled The air guide with the frame is mounted on the front of the vehicle to induce the flow of air generated in the front of the vehicle as the fan frame rotates.This reduces fuel consumption and improves the steering stability of the vehicle. This improves the riding comfort and thereby increases the steering stability of the vehicle.

In addition, the amount of foreign matters such as fly flies that accumulate on the vehicle glass is changed as the fly flies fly along with the flow of air as the vehicle runs, and thus the flow path of the fly flies changes as the air flow is induced by the apparatus of the present invention. This decrease is effective in securing the driver's vision.

Hereinafter, with reference to the accompanying drawings for the configuration and operation of the air resistance reduction device for a vehicle according to the present invention will be described in detail.
