Description

この発明は自転車用変速ハブに関する。   The present invention relates to a bicycle transmission hub.

一般に、自転車の変速システムはディレイラーギヤとハブギヤとに分類することができる。ここに、ディレイラーギヤは、複数の駆動および被動スプロケットを用いて、変速するためにチェーンを移動させ、ハブギヤは、自転車の後輪用のフレームの一部の間に取り付けられ、ハブシェル内のギヤレシオによって変速する。   In general, bicycle transmission systems can be classified into derailleur gears and hub gears. Here, the derailleur gear uses a plurality of drive and driven sprockets to move the chain for shifting, and the hub gear is mounted between parts of the bicycle rear wheel frame, depending on the gear ratio in the hub shell. Shift.

従来のハブギヤは、ギヤ列のギヤレシオによって速度を調整するためにギヤ列をハブシェル内に取り付ける、すなわち、ディレイラーギヤの問題点を解決する革命的方法、というような工夫がなされているが、構造が複雑である。さらに、ハブギヤは低速状態を支持せず、よって、子供や老人が過度の力でペダルを踏む必要がある。さらに、ペダリング中にハブギヤの速度を変えることができない。   The conventional hub gear has been devised such that the gear train is mounted in the hub shell in order to adjust the speed according to the gear ratio of the gear train, that is, a revolutionary method for solving the problem of the derailleur gear. It is complicated. Furthermore, the hub gear does not support low speed conditions, thus requiring children and the elderly to step on the pedal with excessive force. Furthermore, the speed of the hub gear cannot be changed during pedaling.

したがって、この発明は従来技術において生ずる上記問題に鑑みて為されたものであって、この発明の目的は、チェーンが移動しない結果スカートがチェーンで巻き上げられるのを防止でき、容易に変速することができ、簡単な構造を有し、乗り手がペダルを踏んでいる間でも変速でき、子供や老人が簡単で便利な方法で自転車に乗ることができるように低速と高速との間で速度設定ができる自転車用変速ハブを提供することにある。   Therefore, the present invention has been made in view of the above-mentioned problems that occur in the prior art, and the object of the present invention is to prevent the skirt from being rolled up by the chain as a result of the chain not moving and to easily shift the speed. It has a simple structure and can change gears while the rider is stepping on the pedal, and the speed can be set between low and high so that children and the elderly can ride the bicycle in a simple and convenient way. The object is to provide a bicycle transmission hub.

この発明の動作を、図1ないし図4を参照しつつ以下に説明する。   The operation of the present invention will be described below with reference to FIGS.

この発明は、ギヤ列のギヤレシオにしたがって速度を設定するために外部レバーを操作するものに適応される。   The invention is adapted to operating an external lever to set the speed according to the gear ratio of the gear train.

1.低速状態   1. Low speed state

スライド部材420が第1および第3爪330および240を解除するために第1および第爪制御部材450および460を持ち上げるよう移動させられた状態において、ペダルの駆動力が駆動スプロケットを介して被動スプロケット220を駆動する。被動スプロケット220の駆動は、一方を固定されたドライバー210を右回りに回転させる。ドライバー210の回転は、第2爪230を介してリングギヤ310を駆動する。リングギヤ310は、複数の遊星ギヤ320と連係してキャリア340を駆動するために回転する。このとき、キャリア340の回転速度は遅く、そして、キャリア340の回転力は、キャリア340の一端に取り付けられた第4爪350を介して、内側の周辺表面にラチェットが形成されたハブシェル500を駆動し、その結果、自転車を前方へ動かす。
When the slide member 420 is moved to lift the first and third pawl control members 450 and 460 to release the first and third pawls 330 and 240, the driving force of the pedal is driven via the drive sprocket. The sprocket 220 is driven. The driven sprocket 220 is driven by rotating a driver 210 fixed on one side clockwise. The rotation of the driver 210 drives the ring gear 310 via the second claw 230. The ring gear 310 rotates to drive the carrier 340 in conjunction with the plurality of planetary gears 320. At this time, the rotational speed of the carrier 340 is slow, and the rotational force of the carrier 340 drives the hub shell 500 in which the ratchet is formed on the inner peripheral surface via the fourth claw 350 attached to one end of the carrier 340. As a result, the bicycle is moved forward.

2.中速状態   2. Medium speed

スライド部材420が移動させられ、したがって、第1爪制御部材450および第爪制御部材460が、第1爪330を係合させ第3爪240を解除するよう動作する状態において、駆動スプロケットの駆動力が被動スプロケット220を駆動する。被動スプロケット220は、一方を固定されたドライバー210を駆動する。ドライバー210は、第2爪230を介してリングギヤ310を駆動する。リングギヤ310は、リングギヤの一端に取り付けられた第1爪330を介してハブシェル500を駆動する。このとき、遊星ギヤ320はリングギヤ310より遅い速度で回転し、したがって、キャリア340に取り付けられた第4爪350はハブシェル500の回転に全く影響を与えない。
When the slide member 420 is moved and the first claw control member 450 and the third claw control member 460 operate to engage the first claw 330 and release the third claw 240, the drive sprocket is driven. The force drives the driven sprocket 220. The driven sprocket 220 drives a driver 210 having one end fixed. The driver 210 drives the ring gear 310 via the second claw 230. The ring gear 310 drives the hub shell 500 via a first claw 330 attached to one end of the ring gear. At this time, the planetary gear 320 rotates at a slower speed than the ring gear 310, and thus the fourth claw 350 attached to the carrier 340 does not affect the rotation of the hub shell 500 at all.

3.高速状態   3. High speed state

スライド部材420が移動させられ、したがって、第1および第爪制御部材450および460が、第1および第3爪330および240を係合するよう動作する状態において、駆動スプロケットの駆動力が被動スプロケット220を駆動する。被動スプロケット220はドライバー210を回転させる。ドライバー210は、第3爪240を介してキャリア340を回転させる。キャリア340の回転は、遊星ギヤ320を介して、遊星ギヤ320に噛み合ったリングギヤ310に伝達される。このとき、リングギヤ310に伝達された回転はキャリアギヤ340のそれよりも速い。さらに、リングギヤ310の高速回転は、リングギヤ310の一端に取り付けられた第1爪330を介してハブシェル500に伝達され、その結果、自転車を駆動する。
When the slide member 420 is moved and thus the first and third pawl control members 450 and 460 operate to engage the first and third pawls 330 and 240, the driving force of the driving sprocket is driven by the driven sprocket. 220 is driven. The driven sprocket 220 rotates the driver 210. The driver 210 rotates the carrier 340 via the third claw 240. The rotation of the carrier 340 is transmitted to the ring gear 310 meshed with the planetary gear 320 via the planetary gear 320. At this time, the rotation transmitted to the ring gear 310 is faster than that of the carrier gear 340. Further, the high-speed rotation of the ring gear 310 is transmitted to the hub shell 500 via the first claw 330 attached to one end of the ring gear 310, thereby driving the bicycle.

この発明では、ペダリング中の、高速−>中速−>低速、または、低速−>中速−>高速のような速度変更が望まれていることに鑑み、速度変更は、外側の周辺表面に円形のスプラインが形成されるとともに一端がテーパ状のスライド部材420,および、ペダル踏力によって引き起こされる第1および第爪制御部材450および460の回転、によって強制的に行われる。

In the present invention, in view of the desire for speed changes during pedaling, such as high speed-> medium speed-> low speed or low speed-> medium speed-> high speed, the speed change is applied to the outer peripheral surface. A circular spline is formed and one end is tapered by a slide member 420 and rotation of the first and third claw control members 450 and 460 caused by the pedal depression force.

上述のように、この発明は、速度がギヤ列のギヤレシオによって変更できるよう、自転車の後輪のハブの中にギヤ列を組み立てる。その結果、変速が容易に実行でき、そして、外部の汚染物質を遮ることができ、かくして、内部のギヤハブの腐食を抑制する。さらに、ペダリング中に変速したとしても、容易に変速できる。低速、中速、高速の3速の間で変速できるので、老人や子供が容易に自転車のペダルを踏むことができ、そして、乗り手がペダリング中に、強制的に変速を実行することができる。   As described above, the present invention assembles the gear train in the rear wheel hub of the bicycle so that the speed can be changed by the gear ratio of the gear train. As a result, shifting can be easily performed and external contaminants can be blocked, thus inhibiting corrosion of the internal gear hub. Furthermore, even if the gear is changed during pedaling, the gear can be easily changed. Since it is possible to shift between three speeds of low speed, medium speed, and high speed, an elderly person or a child can easily step on the pedal of the bicycle, and the rider can forcibly execute the shift while pedaling.
