Abstract

A coupling device (100) is provided. The coupling device comprises a universal joint (110) and a rotation damping structure (120). The universal joint is connected to a first support member (112) and a second support member (114). The universal joint allows relative rotation between the two support members about a first axis (X) and a second axis (Y) perpendicular to the first axis. The rotation damping structure (120) comprises four damping elements (330). Each damping element comprises a base section (332), a connector section (334), and a yielding section (336). The yielding section extends between the base section and the connector section. The yielding section is configured to plastically deform by a relative rotation (ω_X, ω_Y) between the base section and the connector section. A first pair (130a) of the damping elements are arranged on opposite sides of the universal joint along the first axis. The base sections of each of the first pair of damping elements are fastened to the first support member. A second pair (130b) of the damping elements are arranged on opposite sides of the universal joint along the second axis. The base sections of each of the second pair of damping elements are fastened to the second support member. The connector sections (134a) of each of the first pair of damping elements are fastened to the connector sections (134b) of each of the second pair of damping elements such that the connector sections (134) of the four damping elements form a rigid loop (450) around the universal joint.
