Analysis and Discussion on Design of Empty and Load Car Adjustment Device for Railway Wagon
With the continuous development of heavy haul transportation of railway freight cars,the weight coefficient of freight cars is gradually decreasing,and the total weight difference between empty cars and heavy cars is increasing.At present,the pressure of the brake cylinder of the empty car is about 45%of the pressure of the brake cylinder of the heavy car after the automatic adjustment device of the empty and heavy car is installed on the railway freight car in China,which will not fully meet the application requirements of the braking rate of the empty and heavy car.Through the investigation and analysis of the main type of empty and heavy vehicle ad-justment device at home and abroad,a new type of two-stage automatic adjustment device for empty and heavy vehicles is designed.The device can be matched with the existing main brake in China.Compared with the exist-ing main type of empty and heavy vehicle adjustment device in China,the reliability of the whole braking system is improved to meet the application requirements of domestic heavy haul trains.
