Drum brake module that can electronicly move

The utility model relates to a drum brake module that can electronicly move of motor vehicle, it includes the extension fixture, this extension fixture floating ground just roughly medially sets up between two brake shoes to articulating ground including at least two and connecting each other and support the transmission lever on a brake shoe respectively, wherein, at least one in the transmission lever couples with the executive component of executor, from this, the expansion campaign that the brake shoe was implemented even translation directive and was changed speed in the transmission towards the direction of brake drum. The utility model discloses aim at designing the drum brake module of an effectual improvement, low cost ground just still matches in the application and the characteristics of the motor -driven wheel braking executor in modern times variably but it can be maintained easily. The solution lies in that at least one integration in the transmission lever has can be flexibly reversiblely throu
