Decoupling type brake system with pedal simulator

The invention relates to the technical field of braking systems, in particular to a decoupling type braking mechanism with a pedal simulator. The decoupling type brake mechanism with the pedal simulator is characterized in that: the driving end of a gear transmission mechanism is connected with the pedal simulator; the tail end of the pedal simulator is connected with a main cylinder; the outer side of a lead screw is sleeved with a supporting base; a sleeve is embedded in the inner side of the lead screw; a piston is arranged in the sleeve; one end of the piston is connected with one end of an ejector rod assembly through a damping block base; the other end of the ejector rod assembly is connected with the main cylinder and a push rod assembly; the outer side of a damping block seat is sleeved with a return spring seat; and a belleville spring is arranged in the damping block seat. Compared with the prior art, the mechanism is simple in structure and low in cost, and can realize connection and decoupling of
