Description
次に、出力部材3に出力側機構から回転トルクが逆入力された場合を説明する。
出力部材3に回転トルクが逆入力されると、図5に示すように、出力係合カム12が、1対の係合面部19同士の内側で、出力部材3の回転方向(図5の例では時計方向)に回転する。すると、出力係合カム12の角部が係合面部19を径方向外方に向けて押圧し、1対の係合子5a、5bを、被押圧面15に近づく方向にそれぞれ移動させる。つまり、1対の係合子5a、5bを、係合面部19と出力係合カム12との係合に基づき、遠近方向に関して互いに離れるように径方向外側に(図5の上側に位置する係合子5aを上側に、図5の下側に位置する係合子5bを下側に)それぞれ移動させる。これにより、1対の係合子5a、5bのそれぞれの押圧面16を、被押圧面15に対して押し付ける。この際、押圧面16と被押圧面15とは、押圧面16の周方向に関する全範囲で面接触する。本例の逆入力遮断クラッチ1は、出力部材3に回転トルクが逆入力されると、出力部材3の回転方向に関係なく、1対の係合子5a、5bを、被押圧面15に近づく方向にそれぞれ移動させる。そして、押圧面16と被押圧面15との当接(接触)に基づき、出力部材3に逆入力された回転トルクが入力部材2に伝達されないようにするか又はその一部のみが伝達されるように機能する。出力部材3に逆入力された回転トルクが入力部材2に伝達されないようにするには、押圧面16が被押圧面15に対して摺動(相対回転)しないように、1対の係合子5a、5bを出力係合カム12と押圧部材4との間で突っ張らせ、出力部材3をロックする。これに対し、出力部材3に逆入力された回転トルクのうちの一部が入力部材2に伝達されるようにするには、押圧面16が被押圧面15に対して摺動するように、1対の係合子5a、5bを出力係合カム12と押圧部材4との間で突っ張らせ、出力部材3を半ロックする。
Next, a case where the rotational torque is reversely input to the output member 3 from the output side mechanism will be described.
When the rotational torque is reversely input to the output member 3, as shown in FIG. 5, the output engaging cam 12 is inside the pair of engaging surface portions 19 and the rotational direction of the output member 3 (example of FIG. 5). Then it rotates clockwise). Then, the corner portion of the output engaging cam 12 presses the engaging surface portion 19 outward in the radial direction, and the pair of engaging elements 5a and 5b are moved in the directions approaching the pressed surface 15, respectively. That is, based on the engagement between the engaging surface portion 19 and the output engaging cam 12, the pair of engaging elements 5a and 5b are radially outwardly separated from each other in the perspective direction (engagers located on the upper side in FIG. 5). (5a is moved upward, and the engager 5b located on the lower side of FIG. 5 is moved downward). As a result, the respective pressing surfaces 16 of the pair of engaging elements 5a and 5b are pressed against the pressed surface 15. At this time, the pressing surface 16 and the pressed surface 15 come into surface contact with each other in the entire circumferential direction of the pressing surface 16. In the reverse input shutoff clutch 1 of this example, when the rotational torque is reversely input to the output member 3, the pair of engagers 5a and 5b are brought closer to the pressed surface 15 regardless of the rotational direction of the output member 3. Move to each. Then, based on the contact (contact) between the pressing surface 16 and the pressed surface 15 , the rotational torque reversely input to the output member 3 is prevented from being transmitted to the input member 2, or only a part thereof is transmitted. Works like. In order to prevent the rotational torque reversely input to the output member 3 from being transmitted to the input member 2, a pair of engagers 5a so that the pressing surface 16 does not slide (relatively rotate) with respect to the pressed surface 15 5b is stretched between the output engaging cam 12 and the pressing member 4 to lock the output member 3. On the other hand, in order to transmit a part of the rotational torque reversely input to the output member 3 to the input member 2, the pressing surface 16 slides with respect to the pressed surface 15. A pair of engaging elements 5a and 5b are stretched between the output engaging cam 12 and the pressing member 4, and the output member 3 is half-locked.
