ABSTRACT:
A method for electric braking of a vehicle trailer and a device for vehicle trailers is provided. The vehicle trailer has a rigid hitch or drawbar arrangement (7) and is braked by the overrun forces generated as a result of braking of the tractor vehicle (2). The brake device (1) has a force measuring arrangement which can be mounted at the rigid hitch arrangement (7) and statically records the compression and tension forces acting axially on the hitch arrangement (7) using tensometer strips (24, 25) to determine the wheel brake force needed for braking via a controller that correspondingly actuates the electrical wheel brakes.
