    • A transmission having ratios from 0:1 to 1:1 is disclosed; the transmission comprises a plurality of clutches for producing a partial rotational output from a reciprocating input, an output gear for collecting the partial output of the clutches, an input gear for providing rotational input to a varicrank (i.e. an index plate/web shaft slidably and rotably disposed in a rotatable cylindrical block), and a varicrank (i.e. an index plate/web shaft slidably and rotatably disposed in a rotatable cylindrical block) for producing reciprocal motion on the clutches. The varicrank has a variably offset center web member having a plurality of connecting rods secured thereto corresponding to the number of clutches and a plurality of crank arms pivotally secured to the connecting rods. The ratio of the transmission is adjusted by moving a ratio control rod which increases or decreases the amount of offset of the center web, and accordingly the amount of reciprocating motion applied to the crank arms by the connecting rods.
    • 公开了一种比例为0:1至1:1的变速器; 变速器包括用于产生来自往复输入的部分旋转输出的多个离合器,用于收集离合器的部分输出的输出齿轮,用于向旋转输入提供旋转输入的输入齿轮(即,指针板/腹板轴可滑动地和 可旋转地设置在可旋转的圆柱形块中),以及可变曲轴(即可滑动和可旋转地设置在可旋转的圆柱形块中的折痕板/腹板轴),用于在离合器上产生往复运动。 该曲棍球具有可变地偏移的中心腹板构件,其具有固定到其上的多个连接杆,其中多个离合器和多个可枢转地固定到连接杆上的曲柄臂。 通过移动增加或减少中心腹板的偏移量的比例控制杆来调整变速比,并且因此通过连杆施加到曲柄臂的往复运动的量来调节变速比。

    • A stepless transmission device for a bicycle which has sufficient durability and smooth operation characteristics for practical use is provided. The transmission device can steplessly change the rotational ratio of a wheel to a drive sprocket by changing the oscillation angle of rachet arms which are radially disposed on the periphery of a disk fixed to a shaft for said sprocket. The transmission device is characterized in that said rachet arms incorporated with respective crank arms are pivoted to said sprocket in positions equally distributed on a coaxial circle, and one end of each crank arm constitutes a guide pin, said guide pin being engaged in an annular groove which is coaxially provided in a rotatable bearing race the eccentricity of which can be changed.
    • 提供一种用于自行车的无级变速装置,其具有足够的耐久性和实际使用的平滑操作特性。 传动装置可以通过改变径向设置在固定到所述链轮的轴的盘的圆周上的拉刀臂的摆动角度,来将轮的旋转比率无级地改变为驱动链轮。 传动装置的特征在于,结合有相应的曲柄臂的所述棘爪臂在平行分布在同轴圆上的位置处枢转到所述链轮,并且每个曲柄臂的一端构成导向销,所述导销接合在环形槽 其同轴地设置在可以改变偏心度的可旋转轴承座中。
