Motor driven parking break unit has electric motor and shaft element, where end of shaft element rotates around axis by drive moment of electric motor, and transformation device transforms rotary motion of shaft element

摘要

The break unit has an electric motor (11) and a shaft element (31). An end of the shaft element rotates around an axis by a drive moment of the electric motor. A transformation device (B) transforms the rotary motion of the shaft element into a translatory motion of a parallel translation section (C), which is connected to one end of a cable (13). A parking break (PB) is connected with another end of the cable. A control element (ECU) controls the electric motor by the output of a load sensor (S1), arranged to detect the axial load, and received from another end of the shaft element.
