The invention discloses a safety brake traction device with overspeed protection for an elevator. The safety brake traction device with overspeed protection for the elevator comprises a motor, a quick-start wheel, an outer rotor, an inner rotor, a differential transmission assembly, a speed taking assembly and a brake, wherein the outer rotor and the inner rotor are coaxially arranged; one ends ofthe outer rotor and the inner rotor in the same direction are in transmission connection with the quick-start wheel; and the differential transmission assembly is arranged between the outer rotor andthe inner rotor. The quick-starting wheel comprises a revolution frame and a revolution gear; the outer rotor comprises a sleeve and a wire coil gear; the inner rotor comprises a middle shaft and a speed taking gear; the sleeve is rotationally arranged on the middle shaft in a sleeving mode through a bearing; the wire coil gear with the middle shaft as the axis is arranged at one end of the sleeve; the speed taking gear with the middle shaft as the axis is arranged at one end of the middle shaft; the revolution axis of the revolution frame is the middle shaft; one end of the revolution frameis in transmission connection with the motor; the end, away from the motor, of the revolution frame is radially and inwards provided with a revolution gear capable of rotating; the revolution gear, the wire coil gear and the speed taking gear are bevel gears; and the revolution gear is in meshed connection with the wire coil gear and the speed taking gear towards the two sides.
