Abstract
A linear actuator includes an electric motor, which through a transmission drives a spindle unit having a spindle with a spindle nut. A tubular adjustment element is displaced either outwards or inwards depending on the direction of rotation of the spindle unit. A brake in the shape of a coil spring and a cylindrical element are arranged for retaining the tubular adjustment element in a given position when the power for the electric motor is cut off. The cylindrical element is configured as a separate cylindrical element arranged on the spindle or a shaft in the transmission. The separate cylindrical element is preferably arranged on a rear end of the spindle between the rear mounting and the bearing for the spindle. In contrast to known constructions, the heat generation is limited, as the heat is led out to the rear mounting.
