1. The device for checking overrunning brake efficiency in automobile trailers consists of the pressing part, which contains a double-armed bearer and a servomotor. Characterized in that: The pressing component of the device consists of a pneumatic servomotor (1), with the coupling ball (2) fixed to its housing, while the ball coupling (3) is fixed to the piston rod of the servomotor. The ball coupling is equipped with the double-armed bearer (4), fixed at its base. The tightening cable (5) is fixed on one side of the arms, while the cable catch (6) is fixed on the other side. The servomotor (1) is powered with the pneumatic power supply system, consisting of the source of compressed air (8), the pressure regulator (9), the intermediate pressurised tank (10) with the pressure gauge (11), and the regulating valve (12). The inlet of intermediate pressurised tank (10) is connected through the pressure regulator (9) to the compressed-air source (8), while its outlet is connected through the regulating valve (12) to the inlet of the servomotor piston chamber (1). |
