Abstract

A spindle drive for the motor-driven adjustment of an adjustable element including a housing, a body connector, an adjustable element connector, a spindle nut, a spindle disposed in the housing and operatively connected to the spindle nut and the adjustable element. Either the spindle translate along a drive axis, extending in an axial direction, to move the adjustable element between an open position and a closed position, a planetary gear assembly operatively coupled to and disposed between the spindle nut and the motor, the planetary gear assembly including, a sun wheel, a planet carrier, a gear carried by the planet carrier, an annulus connected to the housing and arranged coaxially to the sun wheel, and a first frictional element non-rotatably fixed with respect to the housing and connected to either the planet gear or the planet carrier. The first frictional element brakes movement of the spindle or the spindle nut.
