Abstract

PROBLEM TO BE SOLVED: To provide a continuously variable speed pulley without changing the position of a driving motor by providing an appropriate number of ball rollers press-engaged at one point on a spherical surface, and providing means for inclining the rotating axes of respective ball rollers concurrently. SOLUTION: When a driving shaft 1 is rotated, a driving wheel 8, six ball rollers 12, a driven wheel 10, and a casing 6 are turned, and a timing belt is driven through a timing pulley 7 which is formed at the one side of the casing 6, to which the timing belt is engaged and tensed. When a handle 19 is turned, respective reciprocating members 11 are reciprocated, which move laterally in the axial direction of a slider 18 screwed by a feed threaded rod 20 and are linked through a rack 17 and a sector gear 21, and the turning shaft of a ball roller 12 is oscillated. A difference is generated between the rotational effective diameter of the driving wheel which is press-engaged with the ball rollers, and the rotational effective diameter of the driven wheel side, thus it is possible to attain continuous speed variation of the casing 6 from a high speed to a low speed.

はハブ53に取付けたV溝リング、532はV溝リング531のV溝531aとL状溝カム572間に挿入したボールである。 The V-groove ring mounted on the hub 53, 532 is a ball that is inserted between the V-grooves 531a and L-shaped groove cam 572 of the V-groove ring 531.

【0036】今従動車57のカムリング571が(a) The cam ring 571 now driven wheel 57 (a)
図において矢印方向に移動すると、カム作用状態となり、(b)図のようにカムリング571が矢印方向に移動すると、フリーホイール状態となる。 Moving in the direction of the arrow in the figure, it becomes camming state, when the cam ring 571 is moved in the arrow direction as shown in (b) view, a freewheeling state.

【0037】以上のように構成されるので、本無段変速装置X3を自転車に搭載してペダルを前進方向に踏むと、チエーンスプロケット54を備えた原動軸51が回転し、原動軸51と原動車56は左ネジ55で螺合しているので、原動車56が図14において左方に移動してボール転動子60との接触圧が増大し、ボール転動子6 [0037] Since the configurations as described above, the pedal and mounting this continuously variable transmission X3 on the bicycle in a forward direction, rotates driving shaft 51 having a chain sprocket 54, the driving shaft 51 and the original Dosha 56 so screwed in the left screw 55, the contact pressure between the ball rolling members 60 driving wheel 56 is moved to the left in FIG. 14 is increased, the ball rolling elements 6
0を介して従動車57が図17の(a)図の矢印のように回動し、カムリング58はカム作用状態となってハブ53を回転させる。 Through 0 is driven wheel 57 rotates as shown by an arrow in (a) of FIG 17, the cam ring 58 to rotate the hub 53 becomes camming state.

【0038】ところが、ペダルを逆に踏むと、原動車5 [0038] However, when pedaling in reverse, driving car 5
6は図14において右方向に移動し、ボール転動子60 6 is moved to the right in FIG. 14, the ball rolling elements 60
との接触圧が落ち、自転車はフリー走行の状態になる。 Contact pressure between the falls, bicycle is in a state of free practice.

【0039】また、ペダルを踏むのを止めた場合には、 [0039] Also, in case you stop stepping on the pedal,
V溝リング531が図17の(b)図のように矢印方向に回動することになるので、この場合も自転車はフリー走行の状態となる。 Because the V-groove ring 531 will rotate in the arrow direction as shown in (b) of FIG 17, also in this case the bicycle is in a state of free running.

【0040】そして、コントロールロッド69をレリーズを介して横動させれば、ボール転動子60の自転軸が揺動し、変速作用は図18に示す様に前記実施例の場合と同様に無段変速させることができる。 [0040] Then, if the traverses through the release of the control rod 69, and rotation shaft swing of the ball rolling element 60, the speed change action as in the case of the embodiment as shown in FIG. 18 No it can be variable transmission.

【0041】以上のように、本発明によれば原動機側を移動させる必要のない無段変速プーリを提供することができ、また、ケーシングを平プーリとすれば、無段変速装置付のコンベアベルト駆動ローラを提供することができる。 [0041] As described above, according to the present invention can provide a continuously variable pulley is not necessary to move the motor side, also, if the casing and the flat pulley, conveyor belt with continuously variable transmission it is possible to provide a driving roller. また、二輪車用の無段変速装置を提供することができる。 Further, it is possible to provide a continuously variable transmission for two-wheeled vehicle.
