The hydraulic component assembly comprises a hydraulic valve block, a plunger pump assembly and a power device, a plunger pump pressure building cavity is formed in the hydraulic valve block, the plunger pump assembly and the power device are arranged on the hydraulic valve block, the plunger pump assembly comprises a piston part and a transmission part, one end of the transmission part is assembled on the right side of the hydraulic valve block, and the other end of the transmission part is assembled on the right side of the hydraulic valve block. One end of the piston part is connected with the hydraulic valve block, the other end of the piston part is connected with the power device, the right end of the piston part is connected with one end of the transmission part, the left end of the piston part extends into the hydraulic valve block, a sealing piece is arranged outside the piston part, and the piston part and the hydraulic valve block are sealed in a sliding mode in a plunger pump pressure building cavity through the sealing piece. The plunger pump pressure building cavity is formed in the hydraulic valve block, the technical scheme that in the prior art, a hydraulic valve block and a plunger pump cylinder body are integrated together is abandoned, the existing hydraulic valve block and the existing plunger pump cylinder body are integrated into one part, the number of parts in the BOM is reduced, management and maintenance cost is reduced, and the leakage risk of a system is reduced.

    本发明涉及一种用于线控液压制动系统的液压部件总成,包括内部设有柱塞泵建压腔的液压阀块、设置在液压阀块上的柱塞泵总成和动力装置,所述柱塞泵总成包括活塞部和传动部,所述传动部一端装配于液压阀块的右侧,其另一端与所述动力装置连接,所述活塞部右端与所述传动部一端连接,所述活塞部左端伸入液压阀块内部,所述活塞部外部设有密封件,并通过所述密封件在柱塞泵建压腔内部与液压阀块滑动密封。通过在液压阀块内部设置柱塞泵建压腔,摒弃了现有技术中将液压阀块和柱塞泵缸体整合在一起的技术方案,通过将现有的液压阀块和柱塞泵缸体整合为一个零部件,减少了BOM里面零部件数量,降低了管理和维护成本,减小了系统泄露风险。
