Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a tread-

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automotive tire driving apparatus capable of deformation of a tread to cope with a change in the performance of the automobile and a change in the condition of the road surface due to a sudden change in environment.

Generally, tires have four functions such as supporting the load of the car, transmitting the driving force and the braking force to the road surface, mitigating the impact from the road surface, and maintaining the switching direction of the automobile.

The most important part of the functioning of these tires is tread, which is the only part directly contacting the road surface among all the parts constituting the automobile. Therefore, tire manufacturers are constantly developing treads of tires by changing their use and performance.

The tread of the tire directly contacting the road surface protects the carcass and the belt layer inside the tire, prevents deformation such as raising and impact, and adopts rubber having high abrasion resistance to increase the running life of the tire. The tread of the tire is engraved with a pattern having grooves and blocks on the tread surface to perform basic functions such as power transmission, braking, and drainage.

Currently, automobile manufacturers are trying to satisfy consumers by changing the mission and suspension to satisfy various driving performance according to road environment and driver's preference while driving.

However, it is difficult to change the tread of a tire, which transmits the driving performance of the vehicle directly to the road surface, unless the vehicle is stopped and replaced. In other words, when the condition of the road surface changes due to a sudden change in environment such as rainfall due to rainfall, snowfall phenomenon due to snowfall in winter or ice, it is necessary to change the tread of the vehicle or replace it with a tire having an appropriate tread. There is a difficulty in this.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an automotive tire driving apparatus capable of tread modification according to the present invention will be described in detail with reference to the accompanying drawings.

Figs. 1 to 6 are views each showing an example of a tread modification by an electric signal or a magnetic signal applied to the present invention. Fig.

As shown in the drawings, the present invention constitutes a part of a tread pattern as a deformable material that changes characteristics such as rigidity when an electric signal or a magnetic signal is given to a tread surface of a tire, to be. That is, in the automotive tire according to the present invention, some of the patterns formed on the tread are formed of a deformable material, and the deformed material changes in stiffness due to the change of the molecular structure due to an electric signal or a magnetic signal.

For example, as shown in Fig. 1, the deformable material is formed in a portion other than the groove of the pattern formed on the tread, and the stiffness is changed by an electric signal or a magnetic signal, so that the surface of the tread other than the groove has a block- . That is, as shown in FIG. 3, portions other than the grooves are projected to reduce the water film phenomenon between the road surface and the tread due to rain, so that the grooves are further deeply and widely changed. As a result, it is possible to prevent the beveled slip.

In addition, the frictional force can be adjusted by adjusting the friction surface with the road surface by deforming the tread. If the ground surface area is widened by using the entire tread without causing deformation of the tread during braking of the vehicle, It is possible to improve the braking ability and to improve the driving ability by deforming the tread in the running direction in order to reduce the resistance due to friction with the road surface during running. That is, as shown in FIG. 2, the deformable material is formed in a strip shape at regular intervals of the left and right of the pattern formed on the tread, and the rigidity is changed by an electric signal or a magnetic signal so that a protrusion in a strip shape is formed to reduce friction with the road surface . Accordingly, the deformable material is protruded in a state where the current friction force is high, thereby reducing the resistance caused by the friction between the road surface and the tire, thereby enhancing the driving ability during driving.

As shown in FIGS. 4 and 5, the deformable material may be formed into a stud shape at regular intervals of up, down, right, and left sides of a pattern formed on the tread, or may be formed in a chain shape at regular intervals The stiffness is changed so that stud or chain protrusion is formed. That is, the snow tires may be provided at regular intervals at upper, lower, left, and right intervals of a pattern formed on the tread so as to form protrusions similar to studs or chains provided on the snow tires in order to prevent slippage on snow roads or ice roads by snowfall or low temperatures, Respectively.

Further, as shown in Fig. 6, the deformable material is formed on the extended line portion of the tire wheel of the pattern formed on the tread so that the stiffness can be changed by an electric signal or a magnetic signal to strengthen the tread of the tire wheel portion. That is, the tread of the tire wheel portion is strengthened in a situation where the running is difficult due to the tire puncture and the air pressure drop due to breakage, so that the tire can be operated like a run flat tire.

Also, although not shown in the drawing, the deformed material may be formed on a portion of the tread pattern that forms the lug pattern, and the stiffness may be changed by an electric signal or a magnetic signal according to the road surface environment to form a lug pattern. That is, in a general situation, in the state of maintaining the rib pattern, the tread becomes a lug pattern when traveling on an unpaved road, so that it is possible to cope with the road surface according to the workplace.

In the above description of the tread deforming function, the respective functions have been described as an example, but the present invention is not limited thereto, and the tread deforming function described above may be mixed and applied freely.

Next, a driving apparatus for a vehicle tire capable of deforming the tread according to the present invention constructed as above will be described in detail with reference to Figs. 7 and 8. Fig.

7 is a view schematically showing the configuration of a tread driving apparatus capable of tread modification according to an embodiment of the present invention, and Fig. 8 is a view schematically showing the structure of an inner wheel for explaining the operation of the driving apparatus of Fig. FIG.

7, the automotive tire driving apparatus according to the present invention includes a driver control unit 10, a control unit 20, a signal generating unit 30, a signal supplying unit 40, a signal holding unit 50, and the like do.

The driver's operating unit 10 is provided in the form of a button in the vicinity of the driver's seat for convenient operation of the driver during driving and generates an on or off signal for tread modification according to the driver's operation and outputs the signal to the control unit 20.

The controller 20 receives an on or off signal for deformation of the tread from the driver's operating unit 10 and outputs an electrical signal or a magnetic signal generated by the signal generating unit 30 based on the key signal to the tread The deformation material 60 is supplied to the deformation material 60 to control the deformation of the deformation material 60 or to stop the supply of the electrical signal or the magnetic signal to the deformation material 60.

The signal generating unit 30 generates an electric signal or a magnetic signal for changing the tread 160 using the rotational force of the driving shaft 110 generated during driving of the vehicle and outputs the electric signal or the magnetic signal to the signal supplying unit 40.

The signal supplying unit 40 supplies the electric signal or the magnetic signal inputted from the signal generating unit 30 to the deforming material 60 provided in the tread 160 of the tire 150 on the basis of the ON operation of the driver's operating unit 10 And outputs to the control unit 20 an electric signal supplied to the deformable material 60 or a feedback signal indicating the interruption of the supply of the magnetic signal based on the off operation of the driver's operating unit 10. [

The signal holding unit 50 maintains the electric signal or the magnetic signal output of the signal supplying unit 40 under the control of the controller 20. [ That is, the signal supply unit 40 performs a switching function to supply an electric signal or a magnetic signal.

The deformable material 60 is provided in a part of the pattern formed on the tread 160 of the tire 150. The structure of the molecule is changed by the electric signal or the magnetic signal inputted from the signal supply unit 40 and the stiffness is changed.

In addition, since the deformation of the tread 160 is easy to use only the change in the friction portion with the road surface rather than keeping the entire surface constant, the lower portion of the inner wheel 130, i.e., the signal supply portion 40 It is preferable that the position of the signal holding portion 50 is positioned in front of the position where the tire 150 and the road surface meet. This is so that the deformable material 60 provided on the tread 160 during the running of the vehicle is deformed before reaching the road surface.

A signal generating unit 30 including a winding coil or a brush is provided in a bearing 140 connecting the inner wheel 130 and the driving shaft 110. The signal generating unit 30 is connected to the inner wheel 130 through a winding coil or a brush The generated electrical signal or magnetic signal is output to the signal supply unit 40 to induce a change in the deformable material 60 provided in the tread 160.

An electric signal or a magnetic signal is applied to the bearing 140 connecting the inner wheel 130 and the drive shaft 110 for the generation of an electric signal or a magnetic signal supplied for changing the deformable material 60 provided on the tread 160 It is preferable to mount a signal generating section 30 capable of generating a magnetic signal. The signal generator 30 has a structure in which a winding coil and a brush are mounted, such as a conventional motor or an alternator, in order to utilize the rotational force of the drive shaft 110, and generates an electric signal or a magnetic signal. The electric signal or magnetic signal inputted through the signal generating unit 30 is supplied as a deformed material in the signal supplying unit 40 based on the operation of the signal holding unit 50 under the control of the controller 20 And the deformed material 60 is changed by the electric signal or the magnetic signal so that the pattern of the tread 160 is changed in the shape of the shape desired by the driver.

On the other hand, as described above, an electric signal or a magnetic signal is generated based on the rotational force of the drive shaft 110 by driving the automobile, and the electric signal or the magnetic signal is outputted at a specific position (i.e., a position before the tire tread comes into contact with the road surface) The tread 160 of the tire 150 is rotated in such a manner as to output an electric signal or a magnetic signal supplied from the inside of the automobile based on the control of the control unit 20, ) May be used.
