The invention discloses an electromagnetic brake assembly special for a new energy pure electric vehicle, which comprises an electromagnetic thrust device and a hydraulic oil pump, wherein the electromagnetic thrust device comprises a main shell; an inner cavity of the main shell is divided into an electric control chamber and a thrust chamber through a thrust chamber partition plate, and the electric control chamber and the thrust chamber are of an up-down structure. A brake electric control board is mounted in the electric control chamber; an electromagnetic thruster is mounted in the thrustchamber; the hydraulic oil pump comprises a sealed oil pump shell, an inner cavity of the oil pump shell is divided into an oil storage chamber and a main piston chamber through an oil pump chamber partition plate, the oil storage chamber and the main piston chamber are of an up-down structure, an oil return hole and an oil inlet hole are sequentially formed in the oil pump chamber partition plate, and a main piston is installed in the main piston chamber to divide the piston chamber into a main oil chamber and an auxiliary oil chamber. In the way, electromagnetic force can be generated by inputting an electric signal to realize active and passive braking functions, and seamless switching and high response characteristics between braking modes are realized, so that a new energy pure electric vehicle and development of an unmanned driving technology have safer and more reliable electronic braking technologies and products with simple structures to be matched with the new energy pure electric vehicle and the development of the unmanned driving technology.
