The invention belongs to the technical field of vehicle braking, and provides a planetary lead screw braking device with variable torque. The invention relates to a torque-variable planetary lead screw brake device which comprises a planetary lead screw assembly, a transmission assembly and a transmission assembly. The planetary lead screw assembly comprises a planetary reducer, a lead screw main shaft and an outer gear ring. One end of the brake transmission part is in transmission connection with the planetary lead screw assembly; the brake transmission part comprises a cantilever assembly frame and a double-shaft hydraulic cylinder; the brake braking part is in transmission connection with the brake transmission part; the brake braking part comprises a brake abutting disc, a brake sleeve, a pushing piston and a pushing outer air bag piece. In conclusion, the planetary lead screw brake device with the variable torque is reasonable in design, easy to operate and capable of effectively achieving flexible transmission and reducing vibration, meanwhile, the adopted planetary lead screw assembly is compact in design, and space is greatly saved; therefore, the device is suitable for industrial popularization.
