Description

本発明は、リニア変速動力伝達機構（ｌｉｎｅａｒｇｅａｒｓｈｉｆｔｐｏｗｅｒｔｒａｎｓｆｅｒｍｅｃｈａｎｉｓｍ）に関し、特に、構造が簡素で小型であり、伝達ロスが少なく、変速時にジャークが発生することを防ぐリニア変速動力伝達機構に関する。 The present invention relates to a linear gear shift power transfer mechanism, and more particularly to a linear shift power transmission mechanism that is simple in structure, small in size, has little transmission loss, and prevents jerk from being generated during a shift.

従来の乗り物には、速度を調整したり燃費を向上させたりするために、変速機構が設けられている。一般の変速機構は、ギヤセットだけ又はギヤセットと油道との組合せにより動力を伝達するが、ギヤセットだけ又はギヤセットと油道との組合せは、構造が複雑で大型であり、伝達ロスが多く、変速時にジャークが発生し易かった。そのため、これらの問題点を改善するために、２つのドラムにＶベルトを組み合わせた無段変速機が開発されたが、ドラム及びＶベルトの体積は大きかった。そのため、構造を簡素かつ小型にし、伝達ロスが少なく、変速時にジャークが発生することを防ぐリニア変速動力伝達機構が求められていた。 A conventional vehicle is provided with a speed change mechanism in order to adjust speed and improve fuel efficiency. A general speed change mechanism transmits power only by a gear set or a combination of a gear set and an oil passage. However, the gear set alone or a combination of a gear set and an oil passage has a complicated structure and a large size, and has a large transmission loss. Jerk was easy to occur. Therefore, in order to improve these problems, a continuously variable transmission in which a V belt is combined with two drums has been developed, but the volume of the drum and the V belt is large. Therefore, there has been a demand for a linear transmission power transmission mechanism that is simple and compact in structure, has a small transmission loss, and prevents the occurrence of jerk during a shift.

本発明の目的は、構造が簡素かつ小型であり、伝達ロスが少なく、変速するときにジャークが発生することを防ぐリニア変速動力伝達機構を提供することにある。 An object of the present invention is to provide a linear transmission power transmission mechanism that is simple and small in structure, has little transmission loss, and prevents jerk from being generated when shifting.

図１及び図７を参照する。図１及び図７に示すように、動力入力回転体５が動力を伝達していないとき、螺旋弾性体７により第１のボール環体４の第１のボール４１を第１のティアドロップ形状凹溝２２の頭部及び第３のティアドロップ形状凹溝５１の頭部（図３を参照する）へ保持する。動力入力回転体５が動力を伝達するとき（逆時計回りに回転するとき）、第１のボール環体４の第１のボール４１が第１のティアドロップ形状凹溝２２の頭部及び第３のティアドロップ形状凹溝５１の頭部により、第１のティアドロップ形状凹溝２２の末端部及び第３のティアドロップ形状凹溝５１の末端部（図３を参照する）へ向かって移動され、動力入力挟持環体２が支持回転体１４の軸方向に沿って伝動球体１３へ向かって移動すると、螺旋弾性体７の両端が引き離される。同じ道理により、動力出力回転体６が動力を伝えていないとき、螺旋弾性体７により第１のボール環体４の第１のボール４１が第２のティアドロップ形状凹溝３２の頭部（図３を参照する）と、第４のティアドロップ形状凹溝６１の頭部とに保持される。動力出力回転体６が動力入力回転体５、動力入力挟持環体２、伝動球体１３及び動力出力挟持環体３（図３を参照する）により、動力を伝えるとき（時計回りで回転する）、第１のボール環体４の第１のボール４１が第２のティアドロップ形状凹溝３２の頭部と、第４のティアドロップ形状凹溝６１の頭部とにより第２のティアドロップ形状凹溝３２の末端部（図３を参照する）及び第４のティアドロップ形状凹溝６１の末端部へ向かって移動し、動力出力挟持環体３が支持回転体１４の軸方向に沿って伝動球体１３へ向かって移動し、螺旋弾性体７の両端を引き離した後、伝動球体１３が内傾斜動力入力環状面２１、内傾斜動力出力環状面３１及び支持回転体１４の外円周面の間に移動可能に挟持されると、動力入力回転体５の動力が動力入力挟持環体２、支持回転体１４及び動力出力挟持環体３を介して動力出力回転体６へ伝達され、動力入力回転体５により動力入力挟持環体２が逆時計回りに回転され、動力入力挟持環体２により伝動球体１３が時計回りで回転され、伝動球体１３により動力出力挟持環体３及び動力出力回転体６が時計回りで回転される。 Please refer to FIG. 1 and FIG. As shown in FIGS. 1 and 7, when the power input rotator 5 is not transmitting power, the spiral elastic body 7 causes the first ball 41 of the first ball ring body 4 to be recessed in the first teardrop shape. The head of the groove 22 and the head of the third teardrop-shaped concave groove 51 (see FIG. 3) are held. When the power input rotator 5 transmits power (when rotating in the counterclockwise direction), the first ball 41 of the first ball ring body 4 has the head of the first teardrop-shaped groove 22 and the third The head of the teardrop-shaped groove 51 is moved toward the end of the first teardrop-shaped groove 22 and the end of the third teardrop-shaped groove 51 (see FIG. 3). When the power input clamping ring 2 moves toward the transmission sphere 13 along the axial direction of the support rotating body 14, both ends of the spiral elastic body 7 are pulled apart. By the same reason, when the power output rotating body 6 is not transmitting power, the spiral elastic body 7 causes the first ball 41 of the first ball ring body 4 to be the head of the second teardrop-shaped groove 32 (see FIG. 3) and the head of the fourth teardrop groove 61. When the power output rotating body 6 transmits power (rotates clockwise) by the power input rotating body 5, the power input holding ring 2, the transmission ball 13 and the power output holding ring 3 (see FIG. 3), The first ball 41 of the first ball ring body 4 has a second teardrop-shaped groove formed by the head of the second teardrop-shaped groove 32 and the head of the fourth teardrop-shaped groove 61. 32 and the fourth teardrop-shaped concave groove 61 move toward the end portion thereof, and the power output holding ring 3 moves along the axial direction of the support rotating body 14. And then the transmission sphere 13 moves between the inner inclined power input annular surface 21, the inner inclined power output annular surface 31 and the outer circumferential surface of the support rotating body 14. When pinched so as to be possible, the power of the power input rotating body 5 is driven. It is transmitted to the power output rotating body 6 via the force holding ring 2, the support rotating body 14 and the power output holding ring 3, and the power input holding ring 2 is rotated counterclockwise by the power input rotating body 5. The transmission sphere 13 is rotated clockwise by the input clamping ring 2, and the power output clamping ring 3 and the power output rotating body 6 are rotated clockwise by the transmission sphere 13.

上述したように、伝動球体１３が内傾斜動力入力環状面２１、内傾斜動力出力環状面３１及び支持回転体１４の円周面に滑り接触されるため、本実施形態のリニア変速動力伝達機構は、構造が簡素で小型であり、伝達ロスが少なく、変速時にジャークが発生することを防ぐことができる。 As described above, since the transmission sphere 13 is in sliding contact with the inner inclined power input annular surface 21, the inner inclined power output annular surface 31, and the circumferential surface of the support rotating body 14, the linear transmission power transmission mechanism of this embodiment is The structure is simple and small, there is little transmission loss, and it is possible to prevent jerk from being generated at the time of shifting.
