Abstract
A drum brake module for motor vehicles operable by electric motor and performs at least one parking brake function, having an electromechanical actuator mounted on one side of the armature plate and a rotational-translational movement converter converting a rotational drive rotational movement into a translational activation movement of brake shoes arranged on a side of the armature plate facing away from the actuator in a brake drum, and including at least one supporting device between the brake shoes such that the latter can carry out an activation movement in the direction of the brake drum. A drive nut is supported by the rotational-translational movement converter in an axially secure and rotatable fashion on the armature plate to assist the braking force. The drive nut drives a spindle arrangement mounted in a rotationally fixed and axially displaceable fashion and engages with an activation cable on at least one brake shoe.
