A pipeline cut-in type hydraulic pump device of a vehicle hydraulic braking system is composed of a pump cavity, a plunger body and an auxiliary execution component of the plunger body. A liquid inlet butted with a foot brake master cylinder is formed in the middle section of the pump cavity, a liquid inlet butted with a rear wheel brake cylinder is formed in the bottom of the pump cavity, and the pump cavity and the plunger body are sleeved to form a plunger type hydraulic pump main body mechanism; an adjusting spring and a spring pressing plate are arranged at the upper section of the plunger body, so that the adjusting spring is pressed down by applying pressure to the spring pressing plate, and then the plunger body is pushed to move from top to bottom, so that oil in the pump cavity is pushed to a liquid outlet to be output; an inhaul cable type mechanical executing mechanism is additionally arranged on one side of the pump cavity, the executing mechanism is in butt joint with a hand brake handle through a brake pull wire, the hand brake handle is controlled to pull the brake pull wire to be in linkage with a spring pressing plate so as to push an adjusting spring and a plunger body, and finally the purposes of hand brake braking and parking are achieved. The device has the characteristics of simple structure and convenience in operation.
一种车辆液压制动系统的管道切入式液压泵装置,由泵腔体和柱塞体及其辅助执行部件组成;在泵腔体的中段设置对接脚刹总泵的进液口,在其底部设置对接后轮制动分泵的进液口,与柱塞体套合成一个柱塞式液压泵主体机构;并在柱塞体的上段设置调节弹簧和弹簧压板,使之通过对弹簧压板施压而压下调节弹簧再推动柱塞体从上往下的运动,从而将泵腔体腔内的油液推向出液口输出;再在泵腔体的一侧附设拉索式机械执行机构,该执行机构通过刹车拉线与手刹手柄对接,使其通过操控手刹手柄来拉动刹车拉线联动弹簧压板而推动调节弹簧和柱塞体,最终达到手刹制动和驻车的目的。具有结构简单,操作轻便的特点。
