DISC BRAKE ACTUATOR

摘要

1. Disc brake actuator with a braking coil (5) mounted inside the end plate (1) which is situated on the fan side, a fan (9) fixed on the free end (8) of the actuator shaft and a rotor disc (10) mounted on the end plate (1), axially displaceable by spring pressure against part of the inside of the fan (9) which thus also acts as a brake disc, with a brake lining (13), preferably ring-shaped, being situated between the rotor disc (10) and the fan (9), and the magnet iron surrounding the coil (5) being embedded in the end plate (1) which consists of a non-magnetic material, in the form of a separate magnet body (2), e. g. a soft-iron ring that is co-axial to the axis (3) of the actuator shaft, characterized by the fact that the end plate (1) is made of aluminium and that the magnet body (2), upon diecasting of the end plate (1), is embedded and, therefore, firmly connected with the end plate through adhesion.
