Abstract
A compact linear actuator having a long stroke is provided. An actuator housing houses a motor having a tubular shaft and a ball nut, both of which are rotatable about an axis. The motor shaft and ball nut are axially spaced and a torque transfer assembly transfers torque from the motor shaft to the ball nut. The assembly includes a torque transfer tube having a first axial end coupled to the motor shaft and a second axial end coupled to a coupling between the tube and ball nut. A ball screw extends through at least a portion of the motor shaft, the tube and the ball nut and outward from the housing and moves along the axis responsive to rotation of the ball nut. The coupling is axially spaced from, and configured for movement along the axis relative to, the tube to prevent transfer of axial loads to the tube.
