Title: (EN) BICYCLE CRANK TRANSMISSION APPARATUS
(ZH) 自行车曲柄变速装置
Abstract: front page image
(EN) The present specification discloses a bicycle crank transmission apparatus that can implement a transmission mechanism using a single chain ring. An embodiment of the aforementioned bicycle crank transmission apparatus comprises: an axial member having an empty space formed therein; a base plate having one side surface coupled with the axial member and an opposite side surface secured to a bottombracket provided with a spindle; a chain ring housing coupled to the axial member so as to be rotatable and having a ring gear fixedly installed therein; a speed reduction gear unit disposed in the center of the ring gear; a directly-coupled ratchet unit installed on the ring gear; a crank cover having, in the center thereof, a vertical coupling shaft coupled with the spindle and, on the inner wall surface thereof, clutch ratchet saw teeth and directly-coupled ratchet saw teeth formed in parallel in the height direction; and a sun gear mounted on the coupling shaft to rotate only in the clockwise direction.
(ZH) 本发明公开一种由单一链环可提现变速机制的自行车曲柄变速装置。所述的自行车曲柄变速装置的实施例包括:轴配件,带有中孔;底板,一侧与所述轴配件相结合,另一侧固定安装于具备主轴的中轴;链环外壳,旋转地结合在所述轴配件,在内部固定安装环形齿轮;减速齿轮单元,配置在所述环形齿轮的中心;直连棘轮单元,安装在所述环形齿轮;曲柄盖,在中央垂直地设置与所述主轴相结合的结合轴,在内侧壁面离合器棘轮锯齿及直连棘轮锯齿以高度方向并列的形成;及太阳齿轮,安装于所述结合轴,只向顺时针方向进行旋转。
