Drive arrangement of a closure-element arrangement of a motor vehicle, wherein the drive arrangement has a drive motor and a feed mechanism which is connected downstream of the drive motor and which serves for generating linear drive movements along a geometrical drive axis, wherein the drive motor and the feed mechanism are arranged in a drivetrain of the drive arrangement and the drivetrain extends between two mechanical drive connections (9, 10) for delivering drive movements, and wherein the drive arrangement has a brake for braking at least a portion of the drivetrain, wherein, during a motorized drive movement for opening the closure-element arrangement and/or during a manual drive movement for closing the closure-element arrangement, the braking action of the brake is reduced with increasing load in the drivetrain, and/or, during a motorized drive movement for closing the closure-element arrangement and/or during a manual drive movement for opening the closure-element arrangement, the braking action of the brake is reduced with increasing load in the drivetrain, wherein the load is a torque transmitted by the drivetrain and/or is a force acting on the drivetrain, which acts on the drive connections (9, 10) from the outside, in particular an axial force in relation to the drive axis, and wherein the brake is arranged between the drive motor and the feed mechanism in the drivetrain, wherein the brake has at least one friction-surface pair for generating the braking action, and the friction-surface pair is preloaded on one another by means of a spring arrangement for achieving the braking action, characterized in that the braking action is reduced by means of a relative displacement along the drive axis of two components (16, 17) in the drivetrain, which are coupled in terms of rotation to the drive motor, as a consequence of an increasing load, in that the drive arrangement has a housing, in that one friction surface of the friction-surface pair is arranged in a rotationally fixed manner on the housing or is provided by the housing and a corresponding friction surface of the friction-surface pair is rotatable and displaceable along the drive axis with the component. wherein the drive arrangement has a drive motor and a feed mechanism which is connected downstream of the drive motor and which serves for generating linear drive movements along a geometrical drive axis, wherein the drive motor and the feed mechanism are arranged in a drivetrain of the drive arrangement and the drivetrain extends between two mechanical drive connections (9, 10) for delivering drive movements, and wherein the drive arrangement has a brake for braking at least a portion of the drivetrain, wherein, during a motorized drive movement for opening the closure-element arrangement and/or during a manual drive movement for closing the closure-element arrangement, the braking action of the brake is reduced with increasing load in the drivetrain, and/or, during a motorized drive movement for closing the closure-element arrangement and/or during a manual drive movement for opening the closure-element arrangement, the braking action of the brake is reduced with increasing load in the drivetrain, wherein the load is a torque transmitted by the drivetrain and/or is a force acting on the drivetrain, which acts on the drive connections (9, 10) from the outside, in particular an axial force in relation to the drive axis, and wherein the brake is arranged between the drive motor and the feed mechanism in the drivetrain, wherein the brake has at least one friction-surface pair for generating the braking action, and the friction-surface pair is preloaded on one another by means of a spring arrangement for achieving the braking action, characterized in that the braking action is reduced by means of a relative displacement along the drive axis of two components (16, 17) in the drivetrain, which are coupled in terms of rotation to the drive motor, as a consequence of an increasing load, in that the drive arrangement has a housing, in that one friction surface of the friction-surface pair is arranged in a rotationally fixed manner on the housing or is provided by the housing and a corresponding friction surface of the friction-surface pair is rotatable and displaceable along the drive axis with the component.
