摘要 |
The present invention discloses a freight car bogie and a freight car. The freight car bogie comprises two wheel sets, two side frames arranged at outer side of said wheel sets, and a bolster fixedly connected to center position of each of said two side frames, respectively. The freight car bogie further comprises a K-shaped supporting device, wherein said K-shaped supporting device passes through preset holes on two sides of an abdominal region of said bolster; a first upper end and a second upper end, as well as a first lower end and a second lower end of said K-shaped supporting device are elastically connected with said two side frames respectively; and said first upper end and second upper end, and said first lower end and second lower end are respectively symmetrical with respect to a center line of said bolster. The K-shaped supporting device of the present application may not pass through the middle part of the bolster so that a reinforcing rib for bearing vertical load can be disposed on the middle part of the bolster, thereby increasing the anti-lozenge-distortion rigidity of the bogie as well as improving the strength of the bolster for bearing the vertical load. |
