The invention relates to a front-drive type wire pulling oil pressure upper pump and a wire pulling oil disc. The front-drive type wire pulling oil pressure upper pump is used in cooperation with a handlebar vertical pipe of a bicycle frame and comprises an upper pump body, a lower pump body and a lower pump body, the two oil cylinder cavities are in through connection with the front assembly cavity; one ends of the oil outlets are respectively communicated with the tail ends of the two oil cylinder cavities, and the other ends of the oil outlets are communicated with the lower end of the rear side of the upper pump body; and the wire pulling oil driving piece comprises a driving part and two piston parts, the two piston parts are movably assembled in the two oil cylinder cavities correspondingly, the driving part is movably assembled in the front assembling cavity, the two piston parts are movably connected with the driving part, and when the two brake steel ropes are independently pulled, oil in the corresponding oil cylinder cavities is output through the oil outlets. The space is saved, the front-drive type wire pulling oil pressure upper pump is arranged in a hidden mode, the possibility that the upper pump is damaged due to collision can be effectively avoided or reduced, and the use and maintenance cost is reduced.
本发明涉及一种前驱式线拉油压上泵和线拉油碟。该前驱式线拉油压上泵搭配一自行车车架的把立管使用,包括有:上泵体,其上开设有:前装配腔;油缸腔,数量为两个,与前装配腔贯通连接;出油口,数量为两个,其一端分别连通两个油缸腔的末端,其另一端贯通于上泵体的后侧下端;线拉油驱件,其包括有驱动部和两个活塞部,两个活塞部分别活动装配于两个油缸腔内,驱动部活动装配于前装配腔内,且两个活塞部与驱动部活动连接,在两个刹车钢绳单独牵引时,使得对应油缸腔的油液通过出油口输出。本发明节省空间,且将前驱式线拉油压上泵隐藏设置,可以有效避免或减少碰撞所导致的上泵损坏可能性,降低了使用和维护成本。
