The invention discloses an automobile brake low-pressure large-capacity energy accumulator which comprises a piston, a reset spring and a sealing cover structure. The sealing cover structure comprises a cover cap and a sealing cover barrel, the sealing cover barrel is connected with the cover cap on the upper portion, the piston is contained in the sealing cover barrel, and a containing groove for containing the reset spring is formed in the piston; and the lower portion of the reset spring is placed in the containing groove of the piston, the upper portion of the reset spring is clamped in the cover cap, an annular groove is formed in the outer wall of the piston in the circumferential direction, and a sealing ring is installed in the annular groove. The piston slides in an inner hole of the sealing cover barrel, under the condition that the width of an aluminum block hole is not changed, the movement stroke of the piston is increased compared with an original scheme, and the volume of the low-pressure energy accumulator is effectively increased. A piston hole of the energy accumulator does not need to be lengthened on a hydraulic valve block, so that the processing cost is reduced; and the valve block volume can be reduced.

    本发明公开了一种汽车制动低压大容积蓄能器,包括活塞、复位弹簧和封盖结构,封盖结构包括盖帽和封盖筒体,封盖筒体与上部的盖帽连接,活塞容纳在封盖筒体内,活塞内部开有放置复位弹簧的容纳槽,复位弹簧下部放置在活塞的容纳槽内,复位弹簧上部卡接在盖帽内,活塞外壁沿圆周方向开有环形槽,环形槽内安装密封圈。活塞在封盖筒体内孔滑动,在不改变铝块孔宽度的情况下,活塞运动行程较原有方案加大,有效提升了低压蓄能器容积。液压阀块上不用加长蓄能器活塞孔,降低了加工费用;阀块体积可减小。
