  • Linear actuator
    Patent number: 9548637
    Abstract: A linear actuator with an electric drive device includes a stator and a rotor, wherein the stator is arranged in a fixed location in a drive housing and the rotor is mounted for rotary motion relative to the stator and with a transmission arrangement which is arranged coaxial with an axis of rotation of the drive device to convert the rotary movement of the rotor into a linear movement, wherein a threaded spindle of the transmission arrangement is non-rotatably connected to the rotor and positively coupled to a spindle nut slidably accommodated in the drive housing and connected to a torque tube, which extends along the axis of rotation, and wherein a brake device is assigned to the rotor and/or to the threaded spindle.
    Type: Grant
