The invention relates to a control drive, in particular a spindle drive for adjusting a swivelable vehicle flap, comprising a housing (), a spindle rod () that is rotatably mounted in the housing (), a first coupling element () for driving a rotational movement of the spindle rod (), and a torque-limiting device () arranged between the first coupling element () and the spindle rod () for limiting the torque transmitted from the first coupling element () to the spindle rod (), comprising an adapter sleeve () arranged at a first end () of the spindle rod () in a rotationally fixed manner, and a first tolerance element () arranged between the spindle rod () and the first coupling element (). According to the invention, a control drive is provided, which is designed such that it is compact and can be economically produced, in such a way that the first tolerance element () is rotationally fixed to one of the first coupling element () and the adapter sleeve ().

Actuating drive comprising a torque-limiting device

A brake arrangement for a drive apparatus, in particular for a drive apparatus for adjusting a vehicle flap, includes a brake housing (), wherein the brake housing () comprises a first brake housing part () and a second brake housing part (), a first brake element () which is arranged non-rotatably in the brake housing (), a second brake element () which is arranged rotatably in the brake housing (), and a preload means () for preloading one of the first brake element () and second brake element () toward the other of the first brake element () and second brake element () in the direction of a longitudinal axis (L) of the brake housing (). The brake housing () has a connecting section () for connecting the first brake housing part () and the second brake housing part (), and in that the first brake housing part () and the second brake housing part () are welded to one another in the connecting section ().

Braking device for a drive device

A brake arrangement for a drive apparatus includes a brake case (), a first brake element (), a second brake element (), and a preload () for preloading one of first brake element () and second brake element () onto the other of first brake element () and second brake element (). A brake arrangement for a drive apparatus, which brake arrangement exhibits a substantially temperature-dependent and consistent braking action, is realized in that an intermediate element () is arranged between the first brake element () and the second brake element (), and the first brake element () and the second brake element () are spaced apart from one another by the intermediate element ().

Brake arrangement for a drive apparatus

Described herein is a spindle drive for the motorized adjustment of an adjustment element of a motor vehicle comprising a drive portion on the spindle side and a drive portion on the spindle nut side, in which the drive portions are able to be adjusted relative to one another in a linear manner for producing drive movements between a refracted position and an extended position and in each case comprising a coupling means for transferring the drive movements and a spring arrangement provided which pretensions the two drive portions in the extended position, wherein a predetermined rupture point is provided in the drive train of the spindle drive which fractures at a predetermined critical load acting via the coupling means on the spindle drive, and which is located outside the flux of force of the spring arrangement.
