The invention discloses a vehicle frame and a vehicle. The vehicle frame comprises a longitudinal beam, a cross beam mechanism and a box body mechanism, the longitudinal beam comprises a first flat beam part, a second flat beam part and an inclined beam part positioned between the first flat beam part and the second flat beam part, and the height of the first flat beam part is lower than that of the second flat beam part; the cross beam mechanism is welded on the first flat beam part and connected with the first flat beam part to form a trapezoid structure; and the box body mechanism is weldedon the second flat beam part and connected with the second flat beam part to form a box body structure. Through the transition of the trapezoid structure to the box body structure from the front to the rear of the vehicle frame, the integral rigidity of the vehicle frame can be effectively guaranteed, the vehicle frame meets the rigidity requirement of working condition use, the reliability of the vehicle frame is improved, the vehicle frame is prevented from being damaged due to excessive local bearing, and the service life of the vehicle frame is prolonged.
本发明公开了一种车架及车辆,其中,车架包括纵梁、横梁机构和箱体机构,纵梁包括第一平梁部、第二平梁部、以及位于第一平梁部和第二平梁部之间的斜梁部,第一平梁部的高度低于第二平梁部的高度;横梁机构焊接在第一平梁部上,与第一平梁部连接后形成梯形结构;箱体机构焊接在第二平梁部上,与第二平梁部连接后形成箱体结构。本发明通过车架从前到后采用梯形结构到箱体结构的过渡,能够有效的保证车架整体的刚度,使车架满足工况使用的刚度需要,提升了车架的可靠性,进而避免了车架因局部承载过大而造成的车架损坏,增加了车架的使用寿命。
