Abstract
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.
