The invention relates to a combined wire pulling oil pressure upper pump and a wire pulling disc brake. The combined line oil pulling and pressing upper pump is used in cooperation with a handlebar stem of a bicycle frame and comprises an upper pump body, a first oil cylinder cavity, a second oil cylinder cavity, a first oil cylinder, a second oil cylinder, a first oil cylinder, a second oil cylinder and a second oil cylinder, and the first oil cylinder cavity and the second oil cylinder cavity penetrate through the middle of the upper pump body and are arranged in parallel; the first oil outlet and the second oil outlet are communicated with the first oil cylinder cavity in the radial direction; the oil way hole and the second oil outlet are coaxially arranged, and the oil way hole is communicated with the first oil cylinder cavity and the second oil cylinder cavity; the two driving parts are arranged in the first oil cylinder cavity and the second oil cylinder cavity respectively; the number of the brake steel ropes is two, the first ends of the brake steel ropes are connected with the two driving parts correspondingly to pull and control the two driving parts to move, so that oil in the first oil cylinder cavity is output through the first oil outlet, and oil in the second oil cylinder cavity is output through the second oil outlet after passing through the oil way hole. And the stable braking effect is achieved by using small braking force.

    本申请涉及一种组合线拉油压上泵和线拉碟刹。该组合线拉油压上泵,其搭配一自行车车架的把立管使用,包括有:上泵体,其内开设有:贯通于上泵体中部且平行设置的第一油缸腔和第二油缸腔;径向连通第一油缸腔的第一出油口和第二出油口;以及,与第二出油口同轴心设置且连通第一油缸腔和第二油缸腔的油路孔;驱动件,数量为两个,分别设置于第一油缸腔和第二油缸腔内;刹车钢绳,数量为两个,其第一端分别与两个驱动件相连接以牵引控制两个驱动件活动,使得第一油缸腔内的油液通过第一出油口输出,以及第二油缸腔内的油液经油路孔后通过第二出油口输出,本申请可有效降低生产成本,且使用较小的刹车力道,达到平稳的刹车效果。
