Abstract: The invention relates to mechanical engineering, notably to brake governors, and can be used in air-operated and cam-operated brake arrangements of vehicles. The brake governor of the vehicle contains a housing used as a lever, which contains a worm gearing consisting of a worm-wheel and a worm screw, a screw gearing consisting of a helical screw and a tooth gear wheel which is arranged coaxially to the worm screw of the worm gearing, which is kinematically connected with it and is limited in its axial movement, and a toothed gearing, the drive pinion of which is arranged coaxially to the worm-wheel of the worm gearing, and the driven gear is arranged coaxially to the helical screw of the screw gearing and is connected with it by means of the drive train comprising a spring-mounted half-coupling with a cam crown at the flank turned to the flank of the helical screw of the screw gearing, which is fixed with the possibility of axial movement relative to the driven gear of the toothed gearing.
