Electromechanical brake for e.g. stopping driving vehicle, has input shaft connected with motor, and rotatable inner gear wheel including output shaft in middle, where output shaft is connected with ball nut that is used as ball screw

摘要

The brake (100) has a gear (50) arranged between a drive motor (60) and a ball nut (41), which is used as a ball screw. The gear includes an input shaft connected with the motor. An outer gear wheel is coupled with the input shaft so that the outer gear wheel is eccentrically rotated. A stationary inner gear wheel and a rotatable inner gear wheel comb with the outer gear wheel so that the outer gear wheel rotates when the inner gear wheels are rotated. The rotatable inner gear wheel includes an output shaft in a middle, where the output shaft is connected with the nut.
