Patent attributes
The invention discloses a three-DOF hybrid damping pantograph, comprising an electric driving transmission system fixed on a base, and collector heads, transverse dampers, parallel support frames as well as longitudinal dampers. Square auxiliary holes are arranged on the base, supporting insulators are arranged on four angles below the base; four transverse dampers are symmetrically fixed on the base, and arranged on the outside of the parallel support frames and connected with the parallel support frames through hinges; four longitudinal dampers are symmetrically fixed on the top of the parallel support frames; the collector heads are connected with the parallel support frames by the longitudinal dampers and separators are arranged on the collector heads. The invention can realize bearing and damping spatially in three directions, avoid pantograph detachment, catenary scraping and other safety accidents, and improve the structural stability of the pantograph and adaptability to the catenary.
