    • PROBLEM TO BE SOLVED: To solve a problem wherein a load gets excessively great in a gear ratio of a high speed gear to be difficult in start by actuating a pedal, when a vehicle stops under the condition where the gear ratio is brought into the high gear ratio during travel at the high gear ratio, in a multi-stage gear type transmission of a bicycle, a problem wherein the gear ratio must be set to restore a low-speed gear suitable for the start, a problem where a pedal is required to be rotated under the state where a rear wheel floats up from a ground face, for switching the gear ratio, and a problem wherein a shift gear is difficult to be switched because a chain is meshed with a gear at strong tension in an ascending slope.
      SOLUTION: A belt comprising an elastomer of varying a width by a tension due to a load rotating a wheel is wound onto a driven pulley and a driving pulley of deep bottom, the belt with the width varying by the tension moves between a bottom side narrow in a V groove width of the driving pulley and an outer circumferential side of wide V groove width, by an elastic force of the belt, and a ratio of an effective diameter to that of the driven pulley varies because a circular arc diameter varies in every moving, in this load sensitive continuously variable transmission by the width variable belt of the present invention.

    • 要解决的问题为了解决在通过启动踏板而开始难以起动的高速齿轮的变速比中的负载变得过大的问题的情况下,当车辆在带有齿轮比的条件下停止时 在高速齿轮比行驶期间,在自行车的多级齿轮式变速器中,要设定齿轮比来恢复适合于起动的低速齿轮的问题,其中a 踏板需要在后轮从地面浮起的状态下旋转,以便切换齿轮比,并且由于链条与强力张力的齿轮啮合,变速齿轮难以切换的问题 一个上坡。 解决方案:包括由于转动车轮的负载而由张力改变宽度的弹性体的带被卷绕到从动带轮和深底部的驱动带轮上,具有由张力变化的宽度的带在一个 驱动带轮的V槽宽度的下侧窄,带宽的V槽宽度的外周侧,由于带轮的有效直径与从动带轮的有效直径的比,因圆弧直径 在本发明的宽度可变带的这种负载敏感的无级变速器中,在每个移动中都是变化的。 版权所有(C)2011,JPO&INPIT
