Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing.
[0025] Such as Figure 1 to Figure 4 As shown, a retractable magneto-rheological damper with built-in permanent magnets in double-outlet rods includes movable earrings 1 at both ends of the piston rod 2, a fixed outer cylinder 10, and an outer shell connected to the power supply 16 arranged on the outer layer of the fixed outer cylinder 10. Set electromagnetic coil 11, the piston 13 that is symmetrically distributed in piston rod 2 two ends; Described fixed outer cylinder 10 is respectively connected with fixed outer cylinder left end cover 20 and fixed outer cylinder right end cover 18 by hexagon socket head cap screw 2;
[0026] It also includes two built-in permanent magnets 14 symmetrically distributed on the piston 13. During the movement, the permanent magnets do not need to be energized, which reduces the internal heating problem; the movable inner cylinder 19 is loc...
