The double-cavity brake control valve comprises a shell, a first oil inlet, a second oil inlet, a first oil outlet, a second oil outlet, a first oil return hole, a second oil return hole, a first spring, a second spring, a sealing ring, a first oil duct, a second oil duct, a third oil duct, a fourth oil duct, an ejector rod, a first piston, a second piston, a first piston cavity and a second piston cavity. The first oil inlet and the second oil inlet of the control valve can be connected with the front brake main pump and the rear brake main pump. The first oil outlet of the control valve can be connected with a front brake pump and can also be connected with a rear brake pump, and the second oil outlet of the control valve can also be connected with the front brake pump and can also be connected with the rear brake pump, so that a front brake main pump and a rear brake main pump on the vehicle can brake the front brake pump and the rear brake pump on the vehicle at the same time. Even if the front brake main pump and the rear brake pump and the rear brake main pump and the front brake pump on the vehicle leak at the same time, the control valve can keep braking force for one of the front brake pump and the rear brake pump of the vehicle.
双腔制动控制阀包括有外壳、第一进油口、第二进油口、第一出油口、第二出油口、第一回油孔、第二回油孔、第一弹簧、第二弹簧、密封圈、第一油道、第二油道、第三油道、第四油道、顶杆、第一活塞、第二活塞、第一活塞腔、第二活塞腔。控制阀的第一进油口与第二进油口,两者均可以连接前刹主泵与后刹主泵。控制阀的第一出油口既可以连接前刹泵,也可以连接后刹泵,第二出油口则同样可以连接前刹泵,也可以连接后刹泵,使车辆上的前刹主泵与后刹主泵,都可以对车辆上的前刹泵与后刹泵同时实施制动。车辆上的前刹主泵和后刹泵以及后刹主泵与前刹泵,即使其中的两个一旦同时产生泄漏,控制阀也可以对车辆的前刹泵以及后刹泵中的一个保持制动力。
