A composite plunger force feedback type hydraulic pressurizing brake pump comprises a brake pump shell combination and a composite plunger combination, the composite plunger combination is arranged in a cavity of the brake pump shell combination in a sliding mode, and the cavity of the brake pump shell combination is divided into an oil inlet cavity, an oil return cavity and a pressurizing cavity. The pressure difference between the oil inlet cavity and the oil return cavity is increased through the pressurizing cavity and then transmitted to the brake, and a tractor or other vehicles are braked. The composite plunger combination comprises a composite plunger and a force feedback plunger, the force feedback plunger is arranged in the composite plunger in a sliding mode, and the magnitude of hydraulic oil flowing damping between an oil inlet cavity and an oil return cavity is controlled or oil way connection between the oil inlet cavity and the oil return cavity is cut off through the sliding stroke of the force feedback plunger; according to the brake pump, the stroke of the feedback control plunger can be controlled through the feedback force of the force feedback plunger, deceleration braking of a tractor or other motor vehicles is achieved, the feedback control plunger can be directly made to move in place, and emergency braking of the tractor or other vehicles is achieved.

    一种复合柱塞力反馈式液动增压制动泵,包括制动泵壳体组合、复合柱塞组合,复合柱塞组合滑动设置在制动泵壳体组合的腔体中,将制动泵壳体组合的腔体分割为进油腔、回油腔、增压腔,进油腔、回油腔之间的压力差经增压腔增大后传输至制动器,对拖拉机或其他车辆进行制动;复合柱塞组合包括复合柱塞、力反馈柱塞,力反馈柱塞滑动设置在复合柱塞中,通过力反馈柱塞的滑动行程控制进油腔、回油腔之间的液压油流动阻尼的大小或关断两腔之间的油路连接;该制动泵可通过力反馈柱塞反馈力大小控制反馈控制柱塞的行程,实现拖拉机或其他机动车辆的减速制动,也可直接使反馈控制柱塞运动到位,实现拖拉机或其他车辆的紧急制动。
