The present invention relates to a coupling apparatus for the pivoted coupling of a vehicle having two vehicle sections, with coupling elements which are arranged to pivot towards each other, and which can be permanently coupled to a vehicle section. A brake arrangement operates between the coupling elements and forms an adjustable frictional grip between the coupling elements, which blocks the ability of the vehicle sections to pivot toward each other. In addition, the brake apparatus includes a hydraulic cylinder unit which operates on multiple radially acting brake elements.
