The present disclosure relates to a support device, in particular for a vehicle flap, comprising a housing () which can be connected between the vehicle flap and the vehicle body and which comprises at least one first housing part () and a second housing part () said the first housing part () and second housing part () are movable relative to each other in a telescopically guided manner. The support device also includes a spindle drive () which is coupled to the housing (). The spindle drive () comprises a spindle rod () and a spindle nut () which is in thread engagement with the spindle rod (), and one of the aforementioned components, i.e. the spindle rod () and the spindle nut (), is rotatably arranged in the housing () about a spindle axis (S) and the respective other component is rotationally fixed in the housing (). The support device also includes a first brake device () which is coupled to one of the aforementioned components in order to brake the rotation of the said component. The first brake device () can be activated by being rotated relative to the housing () about a central rotational axis via centrifugal forces.

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 spring part, in particular for a driving device, includes a spring body extending around a central axis. The spring body comprises several spring windings which run radially around a spring axis and are made of at least a base material. The base material is surrounded at least by a first protective layer, and the spring body is at least partially covered on the outside by a lubricant. A method for manufacturing a spring part includes the steps of providing a spring body with several spring windings made of a base material and coating the base material at least with a first protective layer. The method includes the step of applying a lubricant formed as a silicone-based lubricant to the outside of the coated spring body.

Spring part for a driving device and method of manufacturing a spring part

A brake device for a drivable part, in particular for use for a vehicle flap, in particular in an automobile, includes a drivable load device () which can be radially brought into contact with a disc () of the drivable part, with a first holding position and a second release position. At least one brake element rests against the periphery () of the disc () in a frictional manner in the holding position and secures the disc () from rotating using a specifiable force. In the release position, the at least one brake element is arranged at a distance from the periphery of the disc () and allows a free run of the disc (), and the load device () can be adjusted between the holding position and the release position, preferably by a motor (). A brake device or a rotating drive with which a drivable part of the drive is secured against a displacement on the basis of the mass of the component to be displaced even when the motor is not being provided with power or is deactivated is achieved in that the first holding position and the second release position are each designed as a metastable holding position.

Braking 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 ().
