Abstract
Provided is a car frame. The car frame comprises a first traverse beam, a second traverse beam, a third traverse beam, a fourth traverse beam and a rotary supporting traverse beam which are installed from front to back between two car frame longitudinal beams of a car. The fourth traverse beam comprises a transverse beam main body which is arranged between the two car frame longitudinal beams. Two ends of the transverse beam main body are respectively connected with one transverse beam bearing plate through bolts. The transverse beam bearing plate is connected with an inner side plate of each car frame longitudinal beam through plug welding holes which are formed in the transverse beam supporting plate in a plug welding mode. An outer side of each car frame longitudinal beam is connected with a transverse beam outer flitch which is opposite to the transverse beam bearing plate in a plug welding mode. The car frame is reasonable in structure and greatly enhances the structural strength of the car frame. Positions which need to bear larger impulsive loads in the car frame adopt flexible connection structure, and therefore the impulsive loads are effectively buffered, and anti-torsion capacity and anti-deformation capability under heavy loads are greatly improved. At the same time, added weight of structure is not brought, and the car frame is convenient to maintain and replace.
