The invention relates to a voltage buildup device and an electronic servo braking system. The voltage buildup device and the electronic servo braking system are applied to the electronic servo braking system. The pressure buildup device comprises a cylinder body, a piston assembly, a differential transmission device and a motor. The cylinder body comprises a hydraulic cavity; the piston assembly comprises a piston body and at least two piston blades; the piston body comprises a first piston body and a second piston body which are rotatably connected; first piston blades are arranged on the periphery of the first piston body, second piston blades are arranged on the periphery of the second piston body, and the hydraulic cavity is divided into a plurality of hydraulic chambers by the piston blades; the two ends of the differential transmission device are connected with the motor and the piston assembly respectively. The motor is used for driving the differential transmission device to drive the first piston body and the second piston body to do differential rotation motion, so that the volumes of the multiple hydraulic cavities are changed. In the embodiment of the invention, the differential rotation motion of the first piston body and the second piston body is utilized for pressure building, continuous output of brake fluid with different displacements is achieved, and the brake fluid pressure stabilizing device is suitable for vehicles with different brake pressure requirements.
