Abstract
Abstract Elastic connecting rod (3) for connecting a motor-driven propeller unit to the car body comprising two furthermost seats (4, 5) for inserting hinged elastic elements (6, 7) and a central core (8) between the seats; the core comprises two flanges (10, 11), an upper and a lower one, directed transversally at both sides of the core. Means are provided for maintaining unchanged the distance between the two flanges under stress and for uniformly sharing the load transmitted between the elastic elements and the structure.
