摘要： PROBLEM TO BE SOLVED: To provide a structure of controlling the contact force of a current collector, which can control the contact force working between the slider of the current collector and a trolley wire in spite of its simpleness.
SOLUTION: As shown in figure (A), when contact force C increases and a collector shoe 8 goes up to the slider 7, a pressurizer 18 goes up in a body with the collector shoe 8, and a passage 16 is compressed between the pressurizer 18 and a pressurizer 17, and the sectional area of the passage 16 decreases. As a result, the lift L working on the collector shoe 8 drops, and the contact force C drops. On the other hand, as shown in figure (B), when the contact force C decreases and the collector shoe 8 lowers to the slider 7, the pressurizer 18 lowers in a body with the collector shoe 8, and the interval between the pressurizer 18 and the pressurizer 17 widens, and the sectional area of the passage 16 increases. As a result, the lift L working on the collector shoe 8 increases, and the contact force C increases, and the contact force C is kept roughly constant.

摘要： PROBLEM TO BE SOLVED: To provide a noise suppression structure of a collector shoe capable of reducing noise generated from the collector shoe with a simple structure. SOLUTION: A noise reduction portion 11 is a portion for reducing noise generated at the time of discharging air from an air discharge port 9a. A blade type cross plate 13 is a flat plate in a cross shape for dividing the air discharge port 9a into four and disposed in a flow passage 9c. Linear members 14, 15 are members which cross with the air discharge port 9a, and disposed in parallel to the edge portion on the downstream side of the blade type cross plate 13 with each other. When air flows through the flow passage 9c toward the downstream side from the upstream side, speed inclination of air injected from the air discharge port 9a is relaxed. As a result, when the collector shoe has a lift force control structure for controlling lift force working on the collector shoe by injecting the air from the air discharge port 9a, for example, noise generated from the air discharge port 9a can be reduced.
