Abstract (en)
[origin: EP2060957A1] The member has coaxial barrels (1, 11) comprising cylindrical frames (2, 12) with teeth (3, 13), cylindrical outer drum (4) and drum (14), bottoms (5, 15) and springs (7, 17). The springs are rolled inside the frame and have outer ends coupled with the frames and inner ends coupled to cores (8, 18). The cores are mutually integrated and the bottoms of the barrels are situated axially opposite to each other. The barrels are devoid of lid, and the springs are separated from each other by a separation washer (26) made of antifriction material, where washer extends between the drums of the frames.
