The invention discloses a novel electromechanical actuating mechanism which comprises a box body and a brake head assembly arranged on the box body and used for making contact with wheels for braking, a locking nut is arranged on one side of the box body, and a telescopic mechanism used for pushing the brake head assembly to make contact with the wheels is arranged in the box body. A driving mechanism used for driving the telescopic mechanism to stretch out and draw back is arranged on the lower end face of the box body, the telescopic mechanism comprises a thrust sleeve, a ball screw nut, a ball screw and a connecting assembly, a needle bearing is arranged in the end, away from the brake head assembly, of the thrust sleeve, and the needle bearing is arranged on a locking nut. The device is simple in structure, reasonable in design, convenient to install, compact in structure and beneficial for achieving various functions, the applied braking force is monitored in real time, the collected real braking force is fed back to the controller, and the controller adjusts the input target current by comparing the difference between the real braking force and the target braking force, so that braking force closed-loop control is achieved.
