The embodiment of the invention discloses an oil brake handle which comprises an oil brake knob, a brake oil cylinder, a piston reset spring, a piston and a bearing. A cavity opening is formed in the top of the oil storage cavity, and an oil outlet hole is formed in the bottom of the oil storage cavity; one end of the piston is inserted from the cavity opening, seals the cavity opening and is movably connected with the oil storage cavity, the bearing is arranged at the other end of the piston, and the axis of the bearing is perpendicular to the movement direction of the piston; the oil brake reset spring is arranged in the oil storage cavity, one end of the oil brake reset spring abuts against the bottom of the oil storage cavity, and the other end abuts against the piston; the oil brake knob is provided with an inclined part abutting against the bearing, and when the oil brake knob is rotated, the inclined part extrudes the bearing to drive the piston to move downwards, so that the brake oil in the oil storage cavity is extruded out of the oil outlet hole. Due to the fact that parts on the oil brake handle are arranged in the oil brake knob, the piston is driven to move through the inclined part arranged in the oil brake knob, the structure is compact, the overall occupied space is small, and the oil brake knob is particularly suitable for being applied to a folding bicycle.

    本发明实施例公开了一种油刹把,包括:油刹旋钮、制动油缸、活塞复位弹簧、活塞、轴承;制动油缸具有一储油腔,储油腔顶部具有腔口,底部具有一出油孔;活塞一端由腔口插入,密封腔口并与储油腔活动连接,轴承设置在活塞的另一端,轴承的轴线与活塞的运动方向垂直;油刹复位弹簧设置在储油腔内,其一端与储油腔底部抵接,另一端与活塞抵接;油刹旋钮具有一与轴承抵接的倾斜部,转动油刹旋钮时,倾斜部挤压轴承,带动活塞下移,使得储油腔内的刹车油从出油孔挤出。由于油刹把上的零部件设置到油刹旋钮内部,通过油刹旋钮内部的设置的倾斜部来驱动活塞运动,结构紧凑,整体占用空间小,尤其适合运用至折叠式的自行车使用。
