The invention provides a vehicle frame which comprises a pair of girders and beams arranged between the girders. Each girder comprises a front girder body and a rear girder body. Each front girder body comprises a first web, a first upper wing plate and a first lower wing plate. The cross section of each front girder body is in a groove shape. Each rear girder body comprises a second web, a second upper wing plate and a second lower wing plate. The cross section of each rear girder body is in an I shape. Each first web and the corresponding second web are of an integrated structure. Each first upper wing plate and the corresponding second upper wing plate are fixedly connected to form a first joint. Each first lower wing plate and the corresponding second lower wing plate are fixedly connected to form a second joint. Due to the fact that the girders of the vehicle frame comprise the front girder bodies with the groove-shaped sections and the rear girder bodies with the I-shaped sections, the requirement of a front vehicle frame body for torsion resistance under alternating stress is met, and the requirements of a rear vehicle frame body for loading, installation and welding are met.
