Abstract

1. Load-dependently controlled two-line trailer brake system having the following features : a) the supply line (11, 15), which is fed by a supply connection on the motor vehicle, is connected to at least one reservoir (4), b) the brake line (12, 16), which can be acted upon by way of a brake connection on the motor vehicle, is connected to a load-dependently controllable braking force regulator (5), c) in the connection lines (18, 21, 22) between the reservoir (4) and the brake cylinders (7, 8) there is arranged at least one relay valve (6) which is controlled by the initial pressure of the braking force regulator (5), d) an emergency braking device (3) is arranged in the supply line (11, 15) and in the brake line (12, 16), e) in the emergency braking device (3) there are provided switch-over means (31, 37, 38, 39) which in normal operation allow passage through the supply line and the brake line and which, if the supply feed is reduced or fails, block the brake line (12, 16) and connect the reservoir (4) to the braking force regulator (5), characterised in that the switch-over means (31, 37, 38, 39) respond to the difference between the pressure in the reservoir (4) and the pressure in the part (11) of the supply line (11, 15) lying upstream of the emergency braking device (3).
