Document Type and Number:
Japanese Patent JPH0683570
Kind Code:
B2
Abstract:
In an eddy current type retardation device a cylindrical fixed frame (5) formed of non-magnetic material and having an inner space portion of a rectangular section is arranged between a pair of brake discs (3) connected to a rotational shaft (2), a number of ferromagnetic plates (6) are connected at peripherally equal intervals to both side walls of the fixed frame (5) and a number of permanent magnets (12) are arranged on a magnet supporting ring (8) rotatably supported in the inner space portion of the fixed frame so that every two magnets are opposed to each ferromagnetic plate and every two polarities of two magnets against the ferromagnetic plate are alternately different.
