Claims (5)
- 主軸の外周に入力側部材から回転が入力される爪回転体(1)を嵌め、爪回転体(1)の外周に、変速段数に応じた複数の主ギヤ(2,3,…)を並べて配置し、主軸に平行に設けられ、主軸の周りを公転することのない副軸(6)により、各主ギヤ(2,3,…)に対して所定の速度比で連動する複数の副ギヤ(7,8,…)を一体回転可能に支持し、爪回転体(1)に各主ギヤ(2,3,…)に対応するラチェット爪(15,16,…)を設け、ラチェット爪(15,16,…)が噛合するラチェット歯(19)を各主ギヤ(2,3,…)の内周側に形成し、爪回転体(1)の外周面からラチェット爪(15,16,…)を出没させる切替部材(20)の操作に伴い、ラチェット爪(15,16,…)をラチェット歯(19)に係脱させて、副ギヤ(7,8,…)へ駆動力を伝達する主ギヤ(2,3,…)を切り替え、副ギヤ(7,8,…)から主軸の周りの出力側部材と一体に回転する主ギヤ(5)を介して出力側部材へ回転を伝達することにより、入力側と出力側の回転の速度比を変化させて変速する自転車用変速装置。
- 請求項1に記載の自転車用変速装置において、切替部材(20)を爪回転体(1)の内周側に設け、切替部材(20)の外周に各主ギヤ(2,3,…)ごとに位相をずらして複数の凹部(21)を形成し、爪回転体(1)に対して切替部材(20)を相対回転させ、ラチェット爪(15,16,…)を切替部材(20)の外周に摺接させることにより、ラチェット爪(15,16,…)が爪回転体(1)から出没するようにしたことを特徴とする自転車用変速装置。
- 請求項2に記載の自転車用変速装置において、回転しない固定部材(11,40)と、操作用ワイヤ(25)の引き戻しに伴い回転する操作部材(22)とにそれぞれ差動ギヤ(27)を軸支し、各差動ギヤ(27)を切替部材(20)及び爪回転体(1)に形成した外歯にそれぞれ噛合させると共に、その外側に設けたリング体(28)の内歯にそれぞれ噛合させ、操作部材(22)の回動に伴う切替部材(20)と爪回転体(1)との差動により変速するようにしたことを特徴とする自転車用変速装置。
- 請求項1乃至3のいずれかに記載の自転車用変速装置において、ペダルの踏力により回転するクランク軸(51)を主軸とし、入力側部材となるクランク軸(51)から出力側部材となるフロント側のスプロケット(14)へ回転が伝達されるようにしたことを特徴とする自転車用変速装置。
- 請求項1乃至3のいずれかに記載の自転車用変速装置において、後輪を支持する車軸(61)を主軸とし、入力側部材となるリア側のスプロケット(62)から出力側部材となる外ケース(63)へ回転が伝達されるようにしたことを特徴とする自転車用変速装置。
