Title:
AERODYNAMIC SOUND REDUCTION STRUCTURE OF CURRENT COLLECTOR
Document Type and Number:
Japanese Patent JP2023068891
Kind Code:
A
Abstract:
To provide aerodynamic sound reduction structure of a current collector which can further improve aerodynamic sound reduction effect with a simple structure.SOLUTION: An aerodynamic sound reduction structure 20 reduces aerodynamic sound generated from a current collector 3, and comprises, on a travel direction front side of a shoe supporting part 7 of the current collector 3, a connection arm part 21 which connects a collector head 5 and the shoe supporting part 7 of the current collector 3 with a gap therebetween. The connection arm part 21 comprises a pair of branch parts 21b, 21c which branch toward the collector head 5 side from the shoe supporting part 7 side, and a flow F passes through a gap S between the pair of branch parts 21b, 21c from below to above. In the connection arm part 21, a stem 21a of the connection arm part 21 is connected to the shoe supporting part 7, and tips of the pair of branch parts 21b, 21c are connected to the collector head 5. The pair of branch parts 21b, 21c project forward from the stem 21a of the connection arm part 21 and branch.SELECTED DRAWING: Figure 7
