Abstract: A brake arrangement for a drive apparatus includes a brake case (15), a first brake element (17), a second brake element (19), and a preload (21) for preloading one of first brake element (17) and second brake element (19) onto the other of first brake element (17) and second brake element (19). 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 (20) is arranged between the first brake element (17) and the second brake element (19), and the first brake element (17) and the second brake element (19) are spaced apart from one another by the intermediate element (20).

Abstract: A spindle assembly is for a spindle device, and comprises a spindle nut, which can be brought into thread engagement with a spindle rod, and a tube extending axially along a longitudinal axis, wherein the tube at least partly encircles the spindle nut radially. A spindle assembly for a spindle device is provided. The spindle nut is axially secured to the tube by a welding process.

Abstract: A brake arrangement for a drive apparatus, in particular for a drive apparatus for adjusting a vehicle flap, includes a brake housing (2), wherein the brake housing (2) comprises a first brake housing part (3) and a second brake housing part (7), a first brake element (13) which is arranged non-rotatably in the brake housing (2), a second brake element (15) which is arranged rotatably in the brake housing (2), and a preload means (19) for preloading one of the first brake element (13) and second brake element (15) toward the other of the first brake element (13) and second brake element (15) in the direction of a longitudinal axis (L) of the brake housing (2). The brake housing (2) has a connecting section (11) for connecting the first brake housing part (3) and the second brake housing part (7), and in that the first brake housing part (3) and the second brake housing part (7) are welded to one another in the connecting section (11).

Abstract: The invention relates to a control drive, in particular a spindle drive for adjusting a swivellable vehicle flap, comprising a housing (2), a spindle rod (3) that is rotatably mounted in the housing (2), a first coupling element (5) for driving a rotational movement of the spindle rod (3), and a torque-limiting device (6) arranged between the first coupling element (5) and the spindle rod (3) for limiting the torque transmitted from the first coupling element (5) to the spindle rod (3), comprising an adapter sleeve (8) arranged at a first end (3a) of the spindle rod (3) in a rotationally fixed manner, and a first tolerance element (13) arranged between the spindle rod (3) and the first coupling element (5). 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 (13) is rotationally fixed to one of the first coupling element (5) and the adapter sleeve (8).

Abstract: A drive device, in particular for an adjustable vehicle flap, comprising includes a housing extending axially along a drive axle, a motor for generating a driving force in the direction of the drive axle, a first drive element, and a coupling device arranged between the motor and the first drive element. The coupling device comprises a coupling housing and at least one first coupling part with a coupling section for coupling to the first drive element. The first drive element is coupled to the coupling device via the coupling section of the first coupling part, and a braking device for braking a drive movement of the first drive element. A drive device, in particular for an adjustable vehicle flap, which has a lower residual installation length and can thus be used more flexibly in various installation space situations is created by the braking device being arranged axially in the coupling section of the first coupling part.
