Abstract
A self-unloading freight car is provided by the present application, which includes a car body and a longitudinal centre sill, the car body is installed on the longitudinal centre sill, and oblique end walls are arranged at two ends of the car body. Each of the end walls includes an upper end wall, a lower end wall and a transition wall. A slope of the lower end wall is greater than or equal to a slope of the upper end wall, and a connecting line between an upper end and a lower end of the transition wall has a slope greater than the slope of the upper end wall. When the cargos pass through the transition wall, a frictional resistance generated by the transition wall is less than a frictional resistance generated by the upper end wall, thus the cargos can obtain an additional downward acceleration, which helps the cargos to pass. After the cargos pass through the transition wall, a friction resistance generated by the lower end wall is less than or equal to the frictional resistance generated by the upper end wall, thereby facilitating unloading the cargos smoothly. A wagon having the above self-unloading freight car is further provided by the present application.
