The invention relates to a continuously variable transmission, in particular to a bicycle continuously variable transmission. The invention is realized in the following way: the device mainly comprises a box body, a driving disc shaft, a driving disc, a driven disc shaft, a driven disc, a friction wheel, a friction wheel bracket, a guide rail, a reset device, a speed regulator, a stay rope and a stay rope pipe, and is characterized in that the box body is formed by combining two parts and is provided with a driving shaft hole and a driven shaft hole which are symmetrical and parallel to each other; a plurality of driving discs are sleeved on a driving disc shaft through key grooves, a plurality of driven discs are sleeved on a driven disc shaft through key grooves, the driving discs and the driven discs are arranged in a box body in parallel and mutually clamped, a friction wheel is radially arranged between the driving discs and the driven discs which are mutually clamped, and the friction wheel is movably fixed on a friction wheel support. The friction wheel support is movably fixed on a guide rail in the box body, the friction wheel support is driven by the inhaul cable and the reset device to move on the guide rail, the speed regulator drives the inhaul cable and the reset device to work, and the plurality of pressing wheels are axially fixed in the box body or on the friction wheel support.
本发明涉及一种无级变速器,特别是一种自行车无级变速器。本发明是以如下的方式来实现的:本发明主要由箱体、主动盘轴、主动盘、被动盘轴、被动盘、摩擦轮、摩擦轮支架、导轨、复位装置、调速器、拉索、拉索管组成,其特征是:箱体由两部分组合而成并且设有对称平行的主动轴孔和被动轴孔,数个主动盘通过键槽套在主动盘轴上,数个被动盘通过键槽套在被动盘轴上,主动盘和被动盘平行而且互卡的安装在箱体内,互卡位置的主动盘和被动盘之间径向设有摩擦轮,摩擦轮活动固定在摩擦轮支架上,摩擦轮支架活动固定在箱体内的导轨上,摩擦轮支架由拉索和复位装置带动其在导轨上移动,调速器带动拉索和复位装置工作,数个压紧轮轴向固定在箱体内或者摩擦轮支架上。
