The unidirectional power transmitting device 1 of the present invention comprises an inner ring 100, an outer ring 200, a rotating medium 300, and a transfer release device 400.

The inner ring 100 is formed in a columnar shape. The inner ring 100 is formed in the inner ring so that the drive shaft can be inserted. Therefore, when the drive shaft rotates, the inner ring 100 can rotate.

The inner ring 100 may be formed with a friction-forming portion along the outer circumferential surface thereof.

Accordingly, the inner ring 100 can be engaged with the rotating medium 300, which will be described later, through frictional engagement.

The inner ring 100 is formed with a predetermined thickness. As will be described later, the predetermined thickness of the inner ring 100 is formed not to be at least smaller than the predetermined thickness of the outer ring 200.

The outer ring 200 is formed larger in diameter than the inner ring 100. The outer ring 200 may also be formed in a columnar shape like the inner ring 100. The outer ring 200 may also have a hollow portion to receive the inner ring 100.

The diameter of the hollow portion of the outer ring 200 may be formed to be similar to the diameter of the inner ring 100.

The outer ring 200 may be formed to include a plurality of wedge grooves 202 that are communicated with the hollow portion at predetermined intervals along the circumference and gradually increase in height from one side 202a to the other side 202b .

The outer ring 200 has a predetermined thickness. The predetermined thickness of the outer ring 200 is formed not to be at least smaller than the predetermined thickness of the inner ring 100. [ Therefore, the thicknesses of the outer ring 200 and the inner ring 100 can be made similar.

Here, the shape of the wedge groove 202 may be formed in a tapered shape in which one side 202a is smaller in height than the other side 202b.

The wedge groove 202 may be composed of a communicating portion 203, an upper surface 204, a side surface 205, and the other side surface 206.

One side surface 205 refers to the same portion as the one-side end surface of the wedge groove 202.

The upper surface 204 of the wedge groove 202 is formed in a round shape and a transmitting portion 204a for transmitting the power of the inner ring 100 is formed by fitting a rotating medium 300 to be described later.

The rotating medium 300 is installed in each of the plurality of wedge grooves 202.

The rotating medium 300 may be any type of device that can transfer the rotational force of the inner ring 100 to the outer ring 200 between the wedge groove 200 and the outer peripheral surface of the inner ring 100.

Here, the kind of the embodiment of the rotating medium 300 may be a roller. However, it is natural that the rotating medium 300 is not interpreted as a roller.

The rotating medium 300 may be formed in a cylindrical shape, and a friction forming portion may be formed on the outer circumferential surface. The rotating medium 300 can be engaged with the inner ring 100 through the frictional contact with the outer circumferential surface of the inner ring 100 contacting through the communicating portion 203 and rotate according to the rotation of the inner ring 100.

The rotating medium 300 is moved from the other side 202b of the wedge groove 202 to the one side 202a in accordance with the unidirectional rotation of the inner ring 100 through the frictional coupling as described above, 204a so as to transmit the rotational force of the inner ring 100 to the outer ring 200 to rotate the outer ring 200 as well.

Further, the rotating medium 300 is formed with a predetermined thickness. The predetermined thickness of the rotating medium 300 is not less than the set thickness of the inner ring 100 and the outer ring 200 described above.

Accordingly, the rotating medium 300 can transmit the rotational force of the inner ring 100 to the outer ring 200 stably.

The transfer release device 400 is configured such that the rotating medium 300 is sandwiched between the circumferential surface of the inner ring 100 and the inner surface of the wedge groove 202 to transmit the power of the inner ring 100 to the outer ring 200 Interfere.

That is, the transmission disturbance part is inserted into the space between the end of one side 202a of the wedge groove 202 and the transmission part 204a in which the rotation medium is inserted, and pushes the rotation medium 300 to the other side 202b.

Here, the transfer release device 400 is formed not to be at least thicker than the inner ring 100, the outer ring 200, and the rotating medium 300 described above.

Therefore, the transmission disturbing portion prevents the rotating medium 300 from being engaged in the wedge groove 202 to transmit the rotational force of the inner ring 100 to the outer ring 200.

Here, the transmission disturbance portion may be a pin 401 having a shape protruding from one side surface 205 of the transfer release device 400, according to an embodiment.

The transmission disturbance part is not related to any of the above-described rotating mediums 300 interposed between the transmitting part 204a of the wedge groove 202 and the outer circumferential surface of the inner ring 100 to obstruct the function of transmission of the rotational force.

However, in the present specification, for convenience of explanation, the pin 401 will be described as a transmission disturbance portion.

The pin 401 is composed of a first opposing face 401a and a second opposing face 401b. The first facing surface 401a is a surface facing the one side surface 205 when the pin 401 is inserted into the wedge groove 202 and the second facing surface 401b is a surface facing the rotating medium 300 to be.

The length between the opposing faces of the pin 401, that is, the length between the first opposing face 401a and the second opposing face 401b, And the length of the second end of the second endless belt.

Here, the length between one side surface 205 of the wedge groove 202 and the transmission portion 204a will be described with reference to Fig. 1A, 1B or 3. Four wedge grooves 202 are formed in the unidirectional power transmission apparatus 1 according to the embodiment of the present invention. A wedge groove 202 formed at 12 o'clock direction is referred to as a reference wedge groove 202, would.

A straight line is drawn from one side surface 205 of the reference wedge groove 202 to the other side surface 206 and a straight line extending from the transmitting portion 204a of the upper surface 204 of the reference wedge groove 202 toward the connecting portion 203 When drawn, these straight lines are formed at intersections.

Here, the length between one side 205 of the wedge groove 202 and the transmission portion 204a means the length of a straight line drawn from one side 205 to the intersection.

The reason why the length of the pin 401 is set is that the length of the pin 401 is longer than the length from the one side surface 205 to the intersection point when the pin 401 is inserted into the reference wedge groove 202, 100 and the inner surface of the wedge groove 202 so that power can not be transmitted.

It should be understood, however, that it is natural that any person skilled in the art will be able to embody all such effects as may be practiced in the art without departing from the spirit and scope of the present invention.

Further, the second opposing face 401b is formed with the inclined portion 402.

Here, the inclined portion 402 is formed inclined from the second opposing face 401b toward the first opposing face 401a. When the pin 401 is inserted into the wedge groove 202, the inclined portion 402 is inserted a certain length from the portion where the pin 401 does not abut the rotating medium 300, and then the rotating medium 300 The bar pin 401 pushing the rotating medium 300 to the other side 202b can be smoothly inserted into the wedge groove 202 to cancel the role of the rotating medium 300. [

In addition, the height A of the pin 401 is formed not to be at least greater than one side 205 of the wedge groove 202. [ It will be understood from the foregoing description that one side surface 205 of the wedge groove 202 refers to the same portion as the outer one end surface of the wedge groove 202.

The transfer release device 400 is formed with a hollow portion. This hollow portion is formed by passing through the transfer release device 400 in the axial direction. The hollow portion of the transfer release device 400 may be placed so that the outer ring 200 is centered at one side 202a of the transfer release device 400 in the form of receiving the inner ring 100. [

That is, the centers of the hollow portions of the inner ring 100, the outer ring 200, and the transfer release device 400 may be formed to coincide with each other.

The pin 401 formed in the transfer release device 400 is centered on the transfer release device 400 in a state where the inner ring 100 is received by the outer ring 200 so that the pin 401 can be inserted into one side 202a of the wedge groove 202 And is formed so as to correspond to the position of one side 202a of the wedge groove 202. [

Thus, the pin 401 is formed along the circumferential direction at a predetermined interval from the hollow portion at the position spaced apart from the hollow portion of the transfer release device 400. [

In addition, the transfer release device 400 is formed with a hollow portion having the same center as the inner ring 100 and the outer ring 200, and the drive shaft described above can be inserted into the hollow portion. Therefore, the transfer release device 400 is installed so as to slide the predetermined distance in one direction and the other direction.

That is, the pin 401 is pulled in or pulled out to one side 202a of the wedge groove 202 can be implemented as the transfer release device 400 is slid along the drive shaft at a predetermined distance.

The pin 401 is formed to have a predetermined axial length L so that at least the first opposing face 401a and the second opposing face 401b Of the wedge groove 202 has an axial length that is extended from one side 202a of the wedge groove 202. When the transfer release device 400 moves to the maximum extent in one direction, at least the first opposing face 401a and the The portion where the diameters of the two opposing faces 401b are maintained should be set to have an axial length that can be inserted into one side 202a of the wedge groove 202 to release the engagement of the rotating medium 300. [

The unidirectional power transmission apparatus 1 of the present invention is configured such that when the pin 401 is pulled into the one side 202a of the wedge groove 202, the rotating medium 300 moves to the outer side of the inner ring 100 and the wedge groove 202 Way power transmission device 1 by interrupting the transmission of the rotational force in one direction or the other direction of the inner ring 100 and disengaging the pin 401 from the wedge groove 202 The rotation medium 300 does not interfere with the outer surface of the inner ring 100 and the inner surface of the wedge groove 202 so that the one-way rotational force of the inner ring 100 can be transmitted to the outer ring 200 Way power transmission device 1 is maintained.

The unidirectional power transmitting apparatus 1 of the present invention constructed as above can release the function of transmitting the rotational force of the inner ring 100 to the outer ring 200 in one direction as necessary.

4 is a diagram showing a one-way power transmission apparatus applied to a transmission according to another embodiment of the present technology.

FIG. 5A is a view showing a state in which the function of the one-way power transmitting apparatus applied to the transmission according to another embodiment of the present invention is released, and FIG. 5B is a view showing a state in which the one-way power transmitting apparatus applied to the transmission according to another embodiment of the present invention In which the function is not released.

It can be confirmed that the vertical shaft gear 30 that is engaged with the gear of the second rotary member 20 and rotates with the axis perpendicular to the second rotary member 20 is located at the upper and lower portions of the second rotary member 20 .

Here, though not shown in the vertical axis gear 30, a groove is formed.

When the engaging pin is inserted into the groove of the vertical axis gear 30, the vertical axis gear 30 is prevented from engaging with the second rotating body 20 and rotating.

In addition, it can be seen that the vertical axis gear 30 body is formed to support the vertical axis gear 30 to rotate with the second rotation axis 20 interposed therebetween.

4 is a view showing only a one-way power transmission apparatus 1 according to another embodiment of the present technology.

Way power transmission apparatus 1 according to another embodiment of the present invention is composed of the inner ring 100, the outer ring 200, the rotating medium 300, and the transfer release device 400 described above.

It can be seen that the coupling relationship of each of these configurations is also as described above. The center of the outer ring 200 and the center of the inner ring 100 are disposed on one side surface 205 of the transfer release device 400 in the same manner.

Therefore, as shown in FIGS. 5A and 5B, the second rotating body 20 is inserted into the hollow portion of the outer ring 200, the inner ring 100, and the transfer release device 400.

In addition, the transfer release device 400 is formed in a columnar shape, and a cutout 406 is formed. The cut portion 406 is formed at a position symmetrical with respect to the center of the column of the transfer release device 400. [ That is, if the square of the columnar shape of the transfer release device 400 is drawn in the inside of the columnar shape, the cutout 406 is formed at the corner of the square.

The shape of the cut portion 406 is cut by a predetermined length in a direction perpendicular to either side of the outermost circumference of the circular circumference of the transfer release device 400 and is cut by a predetermined length in the radial direction in the vertically cut portion.

The cut portion 406 is formed in a symmetrical position as described above, so that a total of four cut portions 406 are observed.

The first cut portion and the fourth cut portion, and the second cut portion and the third cut portion are not communicated with each other. That is, the sum of the length cut in the vertical direction by the predetermined length in the first cut portion and the length cut in the vertical direction by the set length in the fourth cut portion is the sum of the length of the portion where the vertical cut of the first cut portion starts, Is set so as to be smaller than the length of a straight line connecting between the portions where the vertical cutting is started. Therefore, there is a portion where the transfer release device 400 is not cut between the first cut portion and the fourth cut portion.

The above description also applies to the second cut portion and the third cut portion.

The transfer release device 400 includes an extension 407 of a shape protruding longer than the pin 401 at the outermost circumference.

Here, it can be seen that the extended portion is formed with a predetermined length and a predetermined thickness. Further, the extending portion includes the inclined portion 402 at one end thereof. That is, the extension portion includes an inclined portion 402 that is inclined from the outer side to the inner side.

4, when the outer ring 200 is arranged on one surface of the transfer release device 400 with its center aligned with the outer ring 200, the outer ring cut portion 207 is formed at a position corresponding to the cut portion 406 do.

Here, the outer ring cutout portion 207 is formed in a similar shape at the same position as the cutout portion 406 of the transfer release device 400.

5A and 5B, a description will be given of an invention in which the one-way power transmitting apparatus 1 according to another embodiment of the present technology is applied to the transmission.

The first rotating body (10) comprises an extension forming part (11). The shape of the extension forming portion 11 is formed extending from the other side of the first rotating body 10 to the other side. The extension forming portion 11 is formed to have a predetermined length and a predetermined thickness. Further, grooves are formed in the elongated portion 11. These grooves are formed at the other central portion of the extension forming portion 11. [ That is, the groove of the elongated forming portion 11 serves to divide the other side of the elongated forming portion 11 into an upper portion and a lower portion.

The extension forming portion 11 formed in this shape connects the vertical axis gear body 40 and the outer ring 200 to the transmission release device 400.

That is, when looking at the first cutout portion of the cutout 406 of the transfer release device 400, the surface of the cutout portion of the first cutout portion is in contact with the surface formed in the longitudinal direction of the extension forming portion 11, The surface of the cut portion in the radial direction of the cut portion is formed with a predetermined thickness of the extend forming portion 11 and is also in contact with the surface formed in the thickness direction of the extend forming portion 11. [

The connection relationship between the extension forming portion 11 and the cut portion 406 is the same for the second cut portion, the third cut portion, and the fourth cut portion.

Also, in the groove of the elongated forming portion 11, a portion remaining without being cut between the first cut portion and the fourth cut portion is located, which is the same as the portion left without being cut between the second cut portion and the third cut portion.

Since the outer ring 200 is disposed on one side surface 205 of the transfer release device 400 and the outer ring cutout portion 207 is formed in the same shape at the corresponding position of the cutout portion 406, It is natural to be connected with.

The vertical axis gear body 40 is connected to the extension forming portion 11 through surface contact. The vertical axis gear body 40 is formed in the shape of "I" so that it can be connected to the elongated forming portion 11 in a surface contact manner through a step formed by the upper and lower steps and a longitudinal direction.

That is, the first rotating body 10 is connected to the vertical axis gear body 40, the outer ring 200, and the transmission release device 400 through the extension forming portion 11. Accordingly, when the first rotating body 10 rotates in one direction, the vertical axis gear body 40, the outer ring 200, and the transfer release device 400 rotate in one direction.

Here, it is natural that the vertical axis gear 30 connected to the vertical axis gear body 40 also rotates in one direction with respect to the first rotating body 10.

The free-rotation state of the transmission will be described with reference to FIG.

When the transmission is in a freely rotating state, the transmission release device 400 slides forward. The pin 401 is drawn into one side 202a of the wedge groove 202 to prevent the rotating medium 300 from being caught between the inner ring 100 and the wedge groove 202. [ Further, the extension portion is in a state in which the engagement pin is lifted by a predetermined length. Accordingly, the vertical axis gear 30 can rotate freely while engaging with the second rotating body 20.

Accordingly, since the vertical axis gear 30 rotates freely by being connected to the second rotary body 20, the vertical axis gear body 40 does not move forward but maintains a predetermined distance from the first rotary body 10, And rotates along the rotating body (10). Here, as described above, it is natural that the unidirectional power transmitting device 1 of the present technology also rotates along the first rotating body 10. [

The connection state of the transmission will be described with reference to FIG. 5B.

When the transmission is in the connected state, the delivery release device 400 is slid rearward. The pin 401 is pulled out from one side 202a of the wedge groove 202 and does not prevent the rotating medium 300 from being sandwiched between the inner ring 100 and the wedge groove 202. [ Further, the extending portion is not in contact with the engaging pin, and the engaging pin is returned to its original position. Therefore, the engaging pin is fitted in the groove of the vertical shaft gear 30, and the vertical shaft gear 30 can not freely rotate by engaging with the second rotating body 20. [

Therefore, the vertical axis gear 30 is connected to the second rotary body 20 and can not freely rotate. Therefore, the vertical axis gear body 40 is rotated along the rotation direction of the first rotary body 10, So that the first rotating body 10 is pressed while closing the set interval with the first rotating body 10.

The first rotating body 10 is pressed to one side and connected to the second rotating body 20 through a multi-plate clutch (not shown) formed at one side of the first rotating body 10. Therefore, the rotational speeds of the first rotating body 10 and the second rotating body 20, which are rotating at different speeds, become equal to each other.

In addition, the unidirectional power transmission device 1 of the present invention is configured such that the pin 401 is drawn out of the wedge groove 202 and transmits power only in one direction. This allows the vertical axis gear 30 and the vertical axis gear body 40 to transmit power only in one direction so that the vertical axis gear 30 and the vertical axis gear body 40 press the first rotating body 10 to one side So as to prevent such pressurization from being released.

Here, in order to return the transmission to the freely rotating state again, simply by moving the delivery release device 400 to one side, it can return to the free rotation state.

The present technology controls the role of the unidirectional power device through the above-described delivery release device 400. [

Accordingly, the rotational force of the inner ring 100 can be transmitted in one direction by implementing the role of the one-way power device, and the rotational force in the one direction or the other direction of the inner ring 100 can be prevented from being transmitted to the outer ring 200, have.

While the present invention has been particularly shown and described with reference to particular embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit of the invention, It will be apparent to those of ordinary skill in the art.
