A drive apparatus for a closure element of a motor vehicle, including a tube defining an axis, a spindle disposed within the tube and configured to move from an extended position to a first retracted position and a second retracted position, a spindle nut disposed within the tube and operatively engaged to the spindle, a stop nut fixed to the spindle, and a damping element disposed between the spindle nut and the stop nut. The tube defines a first end stop face and the stop nut defines a second end stop face, and when the spindle is in the first retracted position, the damping element engages the first end stop face and is spaced apart from the stop nut.

Drive device for a closure element of a motor vehicle

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.

Spindle drive for the motor adjustment of an adjustment element of a motor vehicle

The invention concerns a spindle drive for a closing element () of a motor vehicle (), wherein in a drive train () of the spindle drive (), a drive unit () is provided together with a spindle-nut gear () located drivingly downstream of the drive unit (), with geometric spindle axis (A) running in the axial direction (X), in order to generate linear drive movements of a spindle-side drive connection () relative to a nut-side drive connection () between a retracted position and an extended position of the spindle drive (), wherein in the drive train () a nominal break point () is provided which separates the drive train () at a predetermined axial limit load acting on the spindle drive () via the drive connections (), in particular a tensile load in the direction of the extension position. It is proposed that the drive train () is separated via the nominal break point () between the drive unit () and the spindle-nut gear ().
