Abstract
The invention relates to a subassembly for a brake actuator, which is provided for an electromechanically operated parking brake. The subassembly comprises a drive device and a gearing device, which comprises in succession a first, second and third gear stage for transmitting a torque generated by the drive device. The first gear stage is designed in the form of a gearwheel or belt drive, the second gear stage is designed in the form of a gearwheel mechanism, and the third gear stage is designed in the form of a planetary gear, wherein a planet carrier of the third gear stage receives a first gearing shaft for a sun gear of the planetary gear and an output-side gearwheel of the second gear stage that is coupled to rotate with the sun gear, and bearing elements for planet gears of the third gear stage. The invention further relates to an electromechanical brake actuator and to an electric parking brake, which include the sub-assembly.
