Abstract:
1. A hydraulic trailer brake system comprising a device for braking wheels of a trailer; a controllable pressure generator for wheel-individual or axle-individual activation of wheel brakes; a hydraulic brake force transmission device assigned to the device and connected to the wheel brakes via brake lines, the brake force transmission device including a reservoir for a pressure medium and a brake master cylinder; an electronic control unit or a regulation unit which receives energy via a supply unit, wherein at least two wheel brakes are connected to the brake master cylinder via a first isolating valve arranged in the brake lines and via a first changeover valve, in that the wheel brakes are assigned at least one first inlet and one first outlet valve, a first electrically activatable pressure medium pump provided in a bypass line, downstream of the first changeover valve and the first isolating valve, a stabilizing coupling connected via a second pressure medium pump to actuators which can vary a tension force of the stabilizing coupling between the trailer and a traction vehicle when the pressure medium pump conveys pressure medium out of the reservoir and into or out of the actuators.
