Abstract

The invention relates to a carbon fiber enhanced carbon integrated pantograph slide plate for high-speed railway multiple units. The pantograph slide plate comprises a sliding block (1), a bracket (5) and an air flue (3), wherein the bracket (5) and the sliding block (1) are made of C / C composite materials; in the pantograph slide plate, the carbon fiber enhanced carbon sliding block (1) is adhered to the bracket (5); a groove is formed in at least one of the carbon fiber enhanced carbon sliding block (1) and the bracket (5) along the length direction and is formed in a joint of the carbon fiber enhanced carbon sliding block (1) and the bracket (5); a high-temperature resistant sealing layer (2) is adhered to the groove wall of the groove formed in the carbon fiber enhanced carbon sliding block (1); when the carbon fiber enhanced carbon sliding block (1) and the bracket (5) are adhered integrally, the air flue (3) communicated with an air flue of a fast pantograph reduction device is formed by the high-temperature resistant sealing layer (2) and the bracket (5).

Description

technical field [0001] The invention relates to a carbon fiber-reinforced carbon integrated pantograph slide plate for a high-speed railway EMU; it belongs to the technical field of electric vehicle equipment preparation. Background technique [0002] One of the key technologies of high-speed electrified railways is how to ensure good flow quality under high-speed operating conditions, that is, to maintain stable dynamic flow when the train is running at high speed. With the substantial increase in the operating speed of high-speed trains, the tremendous changes in the operating environment and the structural characteristics of the pantograph-catenary system, the maintenance of a stable current-receiving quality for high-speed trains has put forward higher technical requirements for the pantograph slide. [0003] At present, high-speed railways such as TGV in France, JLH in Germany and KOH in Spain all use pure carbon slides, metal-impregnated carbon slides and carbon-copper...
