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, wherein bearing means for a rotatable mounting of the rotor are provided in opposite end regions of the drive housing.
