摘要：
A block brake actuator comprises in a housing (1) a service brake arrangement, including an electric motor (25, 26) and means (43, 44) for transforming its rotary movement into an axial movement of a push rod (45), and a safety brake arrangement, including at least one powerful spring (11), which acts in a brake application direction, may be tensioned at a service brake application and may be locked to the housing in a tensioned state. The spring is arranged transverse of the push rod and acts thereon over a wedge (8) and roller (5, 7) arrangement.
