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 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.
