Abstract:
An electrically actuated parking brake system and actuator (102) therefor. The actuator (102) includes a motor (200) having a drive shaft, and a gear train coupled to the drive shaft, wherein the gear train provides at least one mechanical output from the actuator (102). The gear train may include a drive gear (202) coupled to the drive shaft, a driven gear (204) coupled to the drive gear (202), and a planetary gear set (206) coupled to the driven gear (204). Various configurations are provided for isolating actuator components for controlling audible noise, including sub-frame isolation configurations, motor isolation configurations, and gear train isolation configurations.
