Abstract

The invention relates to an emergency brake unit (10) and to a vehicle (1) comprising such a unit (10), the emergency brake unit (10) being arranged in a vehicle brake system (20) that comprises:- a fluid line (L)- a pressure source (P) for providing a pressurised fluid to the fluid line (L),- a spring actuated brake (11), which is held in an inactive mode by means of a pressurised fluid acting in a fluid chamber (13) against the action of a spring (12) in the spring actuated brake (11), which fluid chamber (13) is in fluid connection with the fluid line (L),- a pressure regulator (16), which is arranged to govern the spring actuated brake (11) by governing the pressure in the fluid line (L) in fluid connection with the fluid chamber (13) of the spring actuated brake (11),wherein the emergency brake unit (10) comprises:- a valve (14), which is normally in a first open mode, but which may be actuated to a second mode to depressurize the fluid chamber (13) so as to release the spring actuated brake (11) into an active mode in which it provides a braking action to the vehicle (1), wherein the valve (14) is arranged between the spring actuated brake (11) and the pressure regulator (16) in the fluid line (L) immediately upstream of the spring actuated brake (11) so as to override the pressure regulator (16).
