The invention discloses a double-rear-axle truck frame and relates to the technical field of automobile manufacture. The truck frame is divided into a front section, a transition section and a left vertical beam and a right vertical beam which are arranged on the rear section. The outside distance between the left vertical beam and the right vertical beam in the front section is 1080 mm, and the outside distance between the left vertical beam and the right vertical beam in the rear section is 850 mm. A front cover plate and an engine front suspension bend beam are sequentially arranged on the front section, and a first middle beam, a second middle beam, a balance suspension beam and a rear beam are sequentially arranged on the rear section. Two ends of the engine front suspension bend beam are connected with a middle support to be further connected with the left vertical beam and the right vertical beam through plate spring seats. Two ends of the first middle beam, the second middle beam, the balance suspension beam and the rear beam are connected with the left vertical beam and the right vertical beam through connection plates. The truck frame solves the problem that the existing frame is high in mass, low in loading mass and poor in whole truck fuel economy.
