Description

NON-PNEUMATIC TIRE INCLUDING THE BLADE

The present invention relates to a non-pneumatic tire comprising wings.

More particularly, it relates to a non-pneumatic tire including wings that allow wind passing through spokes to flow in a direction conducive to driving and handling of a vehicle.

In general, tires may be mounted on wheels of various vehicles, from small vehicles to heavy-duty vehicles.

Such a tire may perform a function of supporting the load of the vehicle, a function of transmitting the power of the vehicle to the ground, and a function of buffering vibrations and shocks generated during vehicle driving.

Conventionally, most vehicles have used pneumatic tires.

In the case of a pneumatic tire, a pneumatic tire is provided inside, so it has an excellent effect of buffering against collision and flexing.

If the tire is damaged, it is difficult to maintain the internal air pressure, which may reduce the handling and braking ability of the vehicle, resulting in safety problems.

To solve this problem, a non-pneumatic tire that does not require internal air injection has been developed.

As a prior art for a non-pneumatic tire, Korean Patent Application Laid-Open No. 10-2017-0047166 [Document 1] discloses a technical configuration in which a spoke portion extends obliquely with respect to the axial direction of the tire.

In the non-pneumatic tire according to Document 1, the flow of air passing through the spokes may have a constant pattern.

Accordingly, there is a problem in that it is difficult for the flow of air passing through the spokes to help rotation and/or handling of the vehicle.

As another prior art for a non-pneumatic tire, Korean Patent Application Laid-Open No. 10-2016-0101006 [Document 2] discloses a technical configuration in which the edge of the spoke portion is inclined with respect to the axial line of the tire.

Even in the non-pneumatic tire according to Document 2, the flow of air passing through the spokes has a constant pattern, and accordingly, there is a problem in that the flow of air through the spokes does not help the rotation and/or handling of the vehicle.

The rotation control unit 40 may include a motor part 400 , a first differential gear part 420 , and a second differential gear part 430 .

In addition, the rotation control unit 40 may further include a control unit 440 for controlling the motor unit 400 .

The motor unit 400 may provide power (rotation force) for rotating the rotating shaft unit 101 under the control of the control unit 440 .

The first differential gear unit 420 may be connected to a driving shaft 410 of the motor unit 400 . Accordingly, the first differential gear unit 420 may rotate in response to the rotation of the driving shaft 410 .

The second differential gear unit 430 may be engaged with the first differential gear unit 420 . Accordingly, the second differential gear unit 430 may rotate in response to the rotation of the first differential gear unit 420 .

One end E1 of the rotating shaft unit 101 of the rotating spoke unit 100 may be connected to the second differential gear unit 430 . Accordingly, the rotating shaft portion 101 of the rotating spoke unit 100 may rotate in response to the rotation of the second differential gear unit 430 .

Here, the rotating shaft unit 101 of the rotating spoke unit 100 may intersect the driving shaft 410 of the motor unit 400 .

The first differential gear unit 420 and the second differential gear unit 430 may be a bevel gear type or a planetary gear type.

According to this configuration, the rotating spoke unit 100 may be rotated using the rotational force provided by the motor unit 400 .

The control unit 440 may control the motor unit 400 in response to the driving of the vehicle to rotate the rotating spoke unit 100 . Preferably, the control unit 440 may control the motor unit 400 in response to the rotation of the vehicle to rotate the rotating spoke unit 100 .

For example, as shown in FIG. 16A , when the motor unit 400 provides a clockwise rotational force, the first differential gear unit 420 may rotate in the clockwise direction.

Correspondingly, the second differential gear unit 430 rotates in the counterclockwise direction, and accordingly, the rotating spoke unit 100 may rotate in the counterclockwise direction.

On the other hand, as shown in FIG. 16B , when the motor unit 400 provides a counterclockwise rotational force, the first differential gear unit 420 may rotate counterclockwise.

Correspondingly, the second differential gear unit 430 rotates in the clockwise direction, and accordingly, the rotating spoke unit 100 may rotate in the clockwise direction.

In this way, the control unit 440 may control the motor unit 400 to rotate the rotating spoke unit 100 in response to a situation such as rotation while the vehicle is driving.

In detail, the control unit 440 controls the motor unit 400 to determine the rotation pattern of the rotation shaft unit 101 of the rotating spoke unit 10 when the vehicle rotates left and the rotation shaft of the rotating spoke unit 10 when the vehicle rotates right. It is possible to make the rotation pattern of the part 101 different from each other.

In more detail, the control unit 440 may control the motor unit 400 to rotate the rotating shaft unit 101 of the rotating spoke unit 100 in different directions during left and right turns of the vehicle.

For example, as in the case of FIG. 17A , it is assumed that the vehicle 2A travels in a straight line.

In this case, as shown in (B) of FIG. 17 , the first wing part 102 and the second wing part 103 of the rotary spoke part 100 are arranged in parallel in the horizontal direction DRH. can do.

For example, it is possible to maintain a state in which the rotating spoke unit 100 is not rotated.

In this case, since the traveling direction of the vehicle 2A and the directions of the first wing portion 102 and the second wing portion 103 are located in a straight line, the first wing portion 102 and the second wing portion 103 ) may not be generated or a sufficiently small level of lift may occur.

Accordingly, the rotating spoke portion 10 may not interfere with the straight travel of the vehicle 2A.

As in the case of FIG. 18A , it is assumed that the vehicle 2A makes a left turn. In this case, at least one non-pneumatic tire 1A of the vehicle may turn left.

In this case, as shown in (B) of FIG. 18 , the control unit 440 controls the motor unit 400 to move the rotating shaft unit 101 of the rotating spoke unit 100 in the horizontal direction DRH as a reference. can be rotated to the right. Accordingly, the first wing portion 102 and the second wing portion 103 of the rotating spoke unit 100 may rotate to the right with respect to the horizontal direction DRH.

In this case, the lift force may be generated in the right direction opposite to the left direction, which is the rotational direction of the vehicle 2A.

In detail, according to the rotation of the first wing portion 102 and the second wing portion 103 of the rotary spoke portion 100, a wind against the centrifugal force caused by the leftward rotation of the vehicle 2A may be generated. . Accordingly, it is possible to sufficiently suppress or prevent the occurrence of slip of the non-pneumatic tire 1A when the vehicle 2A turns left.

From another point of view, it is possible to suppress or prevent the occurrence of slip of the non-pneumatic tire 1A by strengthening the centripetal force according to the leftward rotation of the vehicle 2A to the lift force.

On the other hand, as in the case of FIG. 19A , it is assumed that the vehicle 2A makes a right turn. In this case, at least one non-pneumatic tire 1A of the vehicle may turn to the right.

In this case, as shown in (B) of FIG. 19 , the control unit 440 controls the motor unit 400 to move the rotating shaft unit 101 of the rotating spoke unit 100 in the horizontal direction DRH as a reference. It can be rotated to the left. Accordingly, the first wing portion 102 and the second wing portion 103 of the rotating spoke unit 100 may rotate to the left in the horizontal direction DRH.

In this case, lift may be generated in the left direction opposite to the right direction, which is the rotational direction of the vehicle 2A.

Accordingly, it is possible to sufficiently suppress or prevent the occurrence of slip of the non-pneumatic tire 1A even when the vehicle 2A turns right.

18 to 19 , the first wing portion 102 and the second wing portion 103 of the rotary spoke portion 100 irrespective of the rotation of the vehicle 2A are of the vehicle 2A. It is possible to maintain an orientation approximately parallel to the vehicle body.
