Abstract
A linear actuator comprising a spindle () with a spindle nut (), where the spindle () is driven by an electric motor () via a transmission (), comprising a planetary gear (). The construction is constructed in such a way that the spindle () is lead through the transmission () and is embedded by means of a ball bearing () in connection with a rear mounting (), causing the axial forces to be lead through the transmission () via the spindle () and the ball bearing () to the rear mounting (). This means that the construction is simpler and less voluminous and that the axial forces, moreover, are not transferred to the transmission.
