The invention relates to the field of vehicle hydraulic suspensions, in particular to an active hydraulic suspension liquid supply unit and a control method thereof.Solenoid valves with relatively small sizes are integrated in a valve block to form an integrated liquid supply unit, and the integrated liquid supply unit comprises a first solenoid valve, a second solenoid valve, a third solenoid valve, a fourth solenoid valve and a one-way pump; the one-way pump is powered by a one-way motor, the first oil supply end of the first electromagnetic valve and the first oil supply end of the third electromagnetic valve are both communicated with a second liquid supply port of the active hydraulic suspension liquid supply unit, and the first oil supply end of the second electromagnetic valve and the first oil supply end of the fourth electromagnetic valve are both communicated with a first liquid supply port of the active hydraulic suspension liquid supply unit. The second oil feeding ends of the third electromagnetic valve and the fourth electromagnetic valve are communicated with the oil outlet end of the one-way pump, the second oil feeding ends of the first electromagnetic valve and the second electromagnetic valve are communicated with the oil inlet end of the one-way pump, control modes of different modes can be provided for a suspension according to different conditions, and therefore various defects of a suspension liquid supply system in the prior art are overcome.

    本发明涉及车辆液压悬架领域,具体涉及一种主动液压悬架供液单元及其控制方法,将体积相对较小的电磁阀集成在一个阀块内,形成集成供液单元,集成供液单元包括第一电磁阀、第二电磁阀、第三电磁阀、第四电磁阀,以及一单向泵,该单向泵由一单向电机提供动力,第一电磁阀、第三电磁阀的第一送油端均连通于主动液压悬架供液单元的第二供液口,第二电磁阀、第四电磁阀的第一送油端均连通于主动液压悬架供液单元的的第一供液口,第三电磁阀、第四电磁阀的第二送油端连通于单向泵的出油端,第一电磁阀、第二电磁阀的第二送油端连通于单向泵的进油端,能够针对不同的情况,给悬架提供不同模式的控制方式,从而避免悬架供液系统在现有技术中的各种缺陷。
