20160076607 | ELECTRIC LINEAR MOTION ACTUATOR AND ELECTRIC BRAKE SYSTEM - An electric linear motion actuator includes a locking mechanism for locking and unlocking the rotor shaft of an electric motor. The locking mechanism includes circumferentially arranged locking holes provided in a gear of a reduction gear mechanism, a locking pin moved toward and away from the locking holes, and engaged in one locking hole to lock the gear when the locking pin is moved toward the gear, and a linear solenoid for moving the locking pin toward and away from the gear. The plunger of the linear solenoid and the locking pin are formed as separate parts, and disposed coaxial with each other with their end faces axially facing each other. This prevents the moment load applied from the gear to the locking pin from acting on the plunger, thereby preventing damage to a bobbin slidably supporting the radially inner surface of the plunger. | 03-17-2016 |
20160131212 | ELECTRIC LINEAR MOTION ACTUATOR AND ELECTRIC BRAKE SYSTEM - The electric linear motion actuator includes an electric motor, a drive shaft configured to be rotated by the electric motor, a rotation-to-linear motion converting mechanism configured to convert the rotational motion of the drive shaft to the axial linear motion of an axially movably supported outer ring member, and an electric locking mechanism incorporated in a reduction gear mechanism in which the rotation of a rotor shaft of the electric motor is reduced in speed and transmitted to the drive shaft. When the electric locking mechanism is energized, the power transmission path shifts to the locked state in which power cannot be transmitted, and when the electric locking mechanism is de-energized thereafter, the power transmission path is kept in the locked state. The electric locking mechanism is built in a motor case of the electric motor so that the electric motor and the electric locking mechanism are unitized. | 05-12-2016 |
