Description

Auto active damping device

Affiliated technical field

The present invention relates to a kind of vehicle energy saving product, especially auto active damping device, belong to the automobile energy-saving technology field.

Background technology

At present, the technology that is used to reduce the automobile air resistance often need change car conour etc. by braking technique or improve the Facing material of automobile itself, cost is very high, and the effect that reduces the automobile air resistance is also not obvious, and the drag-reduction effect of these methods can not be greatly improved.

Summary of the invention

In order to overcome the deficiency of existing automobile resistance-reducing technology, the invention provides initiatively resistance absorber of a kind of energy-saving automobile.

The technical solution adopted for the present invention to solve the technical problems is: auto active damping device comprises preceding driven shaft, goes up driven shaft, driven shaft, back driven shaft and variable-frequency motor under driven shaft, the roof on driven shaft, imput shaft, drag reduction film, the roof down; The drag reduction film is the sealing belt composition, driven shaft and back driven shaft before its two ends are penetrated with, and the centre is penetrated with down driven shaft on driven shaft and the roof; Following driven shaft is in drag reduction film inside face, last driven shaft and imput shaft are in the drag reduction film outer surface, the three is close to parallel installation up and down, driven shaft is in drag reduction film inside face on the roof, driven shaft is in the drag reduction film outer surface under the roof, both are close to parallel installation up and down, and imput shaft is connected by gear with variable-frequency motor.

The drag reduction film is installed in the automobile upper surface, when galloping, according to the rotation of speed of a motor vehicle control variable-frequency motor, drive drag reduction film and the equidirectional high-speed operation of air fluid, the drag reduction film produces guide functions at the automobile upper surface, increase the air-flow relative velocity of air and automobile upper surface, thereby reduced the air resistance of automobile.

Beneficial effect of the present invention is, adopted the active drag reduction technology of autonomous dynamic, at the automobile upper surface drag reduction film is installed, and reduces the air resistance of automobile when running at high speed, and it is simple in structure, and is safe and reliable, and is energy-saving and cost-reducing, is fit to the use of all kinds of means of deliverys.

Fig. 3 is the birds-eye view of Fig. 2.

Parts and numbering among the figure:

The 1-driven shaft; The last driven shaft of 2-; Driven shaft under the 3-; The 4-imput shaft; 5-drag reduction film;

Driven shaft on the 6-roof; Driven shaft under the 7-roof; Driven shaft behind the 8-; The 9-variable-frequency motor.

The specific embodiment

The present invention is further described below in conjunction with drawings and Examples.

Present embodiment is an example with common three casees cars, as Figure 1-3, auto active damping device, is gone up driven shaft 2, driven shaft 7, back driven shaft 8 and variable-frequency motor 9 under driven shaft 6, the roof on driven shaft 3, imput shaft 4, drag reduction film 5, the roof down at driven shaft 1 before comprising; Drag reduction film 5 is the sealing belt composition, driven shaft 1 and back driven shaft 8 before its two ends are penetrated with, and the centre is penetrated with down driven shaft 6 on driven shaft 3 and the roof; Following driven shaft 3 is in drag reduction film 5 inside faces, last driven shaft 2 and imput shaft 4 are in drag reduction film 5 outside faces, the three is close to parallel installation up and down, driven shaft 6 is in drag reduction film 5 inside faces on the roof, driven shaft 7 is in drag reduction film 5 outside faces under the roof, both are close to parallel installation up and down, and imput shaft 4 and variable-frequency motor 9 are connected by gear.

Drag reduction film 5 is installed in the automobile upper surface by imput shaft 4 and a series of driven shaft, parallel installation between its imput shaft 4 and each driven shaft.When galloping, according to 9 rotations of speed of a motor vehicle control variable-frequency motor, variable-frequency motor 9 is by gear transmission imput shaft 4, drive drag reduction film 5 and the equidirectional motion of air fluid, variable-frequency motor 9 is powered by automotive battery, by autometer control variable-frequency motor 9 rotating speeds, adopt partially sealed measure between drag reduction film 5 and the car body.

The high-speed operation of drag reduction film 5, its linear velocity be than the high 1%-30% of the speed of a motor vehicle, thereby significantly increase the relative velocity of the main windward side of air and automobile top, thereby reduced the air resistance of automobile significantly.

The air flows of car body bottom is identical with traditional approach, according to fluid mechanics principle: because the guide functions of the drag reduction film 5 of car body upper surface, make the air rate of car body upper surface greater than car body bottom, make car body produce certain lift, reduced car body to ground-surface pressure, car body is reduced surface pressure and friction force, thereby further reduced automobile power consumption.

Fairing also can be installed in the car body bottom, further increases drag-reduction effect.

Drag reduction film 5 is high transparent flexible material, when travelling in the rainy day, can artificially control the high-speed operation of drag reduction film 5, replaces windshield wiper, and it is better to blow the existing windshield wiper of rain effect.

In conjunction with the accompanying drawings the specific embodiment of the present invention has been carried out the description of exemplary above, obviously the invention is not restricted to this, the various remodeling that carry out within the scope of the present invention all do not exceed the protection domain of invention.
