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.
Abstract:
An electro-mechanical actuator is provided resisting back driving of a gear train in at least one direction. The actuator includes an internal gear train (101). A clutch (111) is coupled to an output of the gear train and transmits a driving force from the gear train to a clutch output. When a back driving force is applied to the clutch output in at least one direction, the clutch assumes a locked configuration. When the clutch is in a locked configuration the clutch resists rotational movement of the output and back driving of the gear train.
Abstract:
A steering shaft lock actuator may include a motor having an output shaft, a drive train, and a lost motion device. The drive train may be coupled to the output shaft and may linearly urge a locking member to an unlocked position when the motor is energized. The lost motion device may be configured to store energy when the locking member is in the unlocked position and utilize the stored energy to drive the locking member toward a locked position with a steering shaft when the motor is de-energized.
Abstract:
An actuator including a plurality of mounts (42-50) for facilitating connection of the actuator to a variety of mounting bracket configurations for securing the actuator within an assembly. Also provided is a clutch assembly (26) including an input member (90), an output member (80),and pawls (104). Torque is transferred through the clutch when applied to the input member in a clockwise or counter-clockwise direction. When torque is applied to the output member, the clutch permits rotation in only one direction of rotation.
