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.
A drum brake module for motor vehicles, which drum brake module can be operated by an electric motor, comprising an electromechanical actuator that is fastened to an outer face of an anchor plate for the purpose of operating a rotation to translation converter for converting a rotary drive rotational movement into a translation actuating movement of brake shoes that are arranged in a brake drum on an inner face of the anchor plate, which inner face is remote from the actuator, so that said brake shoes can perform an actuating movement in the direction towards the brake drum, wherein a drive nut of the rotation to translation converter is supported in an axially fixed and rotatable manner on the anchor plate in order to support the brake force, and wherein the drum brake module further comprises a lever movable in a defined elastic manner, the lever comprising a plurality of limbs, at least one of the limbs forming a stop that is positioned to change an elastic deformation of the lever as the lever is moved.
The drum brake module for motor vehicles, as claimed in 2, wherein the gear housing or the motor comprise at least one electrical interface that is embodied as a male connector or a female connector, said interface being used to provide an electrical connection to an electronic control unit and/or an electric switch.
A drum brake module for motor vehicles, which drum brake module can be operated by an electric motor, comprising an electromechanical actuator that is fastened to an outer face of an anchor plate for the purpose of operating a rotation to translation converter for converting a rotary drive rotational movement into a translation actuating movement of brake shoes that are arranged in a brake drum on an inner face of the anchor plate, which inner face is remote from the actuator, so that said brake shoes can perform an actuating movement in the direction towards the brake drum, wherein a drive nut of the rotation to translation converter is supported in an axially fixed and rotatable manner on the anchor plate in order to support the brake force, wherein a currentless self-locking arrangement of the rotation to translation converter is coupled to the actuator.
