    • The invention relates to an arrangement and method for detecting failure of an electromechanical brake (1) in an electromechanical drive system (100). The arrangement being characterized in that it comprises a control unit (11) arranged to: send a drive torque signal to an electrical traction motor (4) in the electromechanical drive system (100) while the electromechanical brake (1) is in an active braking position, detect if said applied drive torque causes a driving movement in the electrical traction motor(4), and indicate a mechanical failure of the electromechanical brake (1) in case a driving movement in the electrical traction motor (4) is caused by said applied drive torque. The invention further relates to a method for detecting failure of an electromechanical brake (1) in an electromechanical drive system (100), and an industrial truck comprising the arrangement.
    • 本发明涉及一种在布置和方法用于向机电制动的机电驱动系统中检测的失败(1)(100)。 该装置的特征在于,这样做是包括被布置成控制单元(11):在所述机电驱动系统(100),同时所述机电制动器(1)是在主动制动发送驱动转矩信号在电牵引电动机(4) 位置,检测是否所述施加的驱动扭矩导致的电牵引电动机(4)的驱动移动,并指示的情况下的机电制动器(1)在电气牵引电动机的驱动运动的机械故障(4)由所述致 施加的驱动扭矩。 本发明进一步涉及一种用于检测电动机械驱动系统(100)的机电制动器(1)的故障,并且在工业卡车,其包括布置。
