Hole Position Adjustment Research of Bogie Brake Device for C80EF General Gondola
This paper briefly introduces the structure of C80EF general brake device.Based on the actual operation and inspection of the brake device of C80EF general gondola,the detailed analysis is performed about the influence of the wearing sum of wheel and brake shoe from the key parameters such as bogie brake device,ST2-250 slack adjustment assembly(for short:slack adjustment,the below is the same)and so on,the relationship is obtained between the wearing sum of wheel and brake shoe among dead lever lug,down pull rod and slack adjustment.The suitable gondola brake device adjustment rule is formulated according to the wheel wearing statistic data of the C80EF general gondola.And the essential verification is completed for supporting the adjustment rule.The analysis and verification show that the adjustment rules of C80EF general gondola bogie brake device in this paper have certain practical and promotional value.
