An electric linear actuator includes a housing extending along a longitudinal axis, the housing configured to be coupled to a first component. A spindle is provided in the housing and extends along the longitudinal axis from a proximal end to a distal end. A motor is coupled to the proximal end of the spindle and is configured to rotate the spindle. A spindle nut is received on the spindle and is movable with respect to the housing along the longitudinal axis in response to rotation of the spindle. The spindle nut is configured to be coupled to a second component. A one-way bearing prevents back-drive of the motor when an external load is applied to the second component while the motor is not provided with electrical power.

Electric linear actuator with anti-backdrive mechanism

An actuator may include a housing, a ball screw engaged with the housing, a tie rod disposed in the ball screw, a plurality of friction springs in the ball screw and around the tie rod, and a bearing having an interference fit with the tie rod and a clearance fit with the ball screw.
