As preferably; Said bottom chassis module comprises two main longitudinal griders that are parallel to each other and extend; Arch upward in the relative stage casing with back segment of said two main longitudinal grider leading portions; Be provided with front cross rail between the leading portion of said two main longitudinal griders, be provided with center member between the stage casing of two main longitudinal griders, be provided with after cross member between the back segment of two main longitudinal griders.Crisscross connection structure intensity is better, and the middle part of bottom chassis sinks to forming drop, three platforms before, during and after like this whole chassis being divided into, and front platform is a forward engine room, and middle deck is driving compartment and passenger accommodation, and back platform is a trunk.
As preferably, the number of said front cross rail, center member and after cross member is at least two, and keeps being equally spaced.Because the bottom chassis module will form three carrying platforms, and each carrying platform all will support by two crossbeams at least, so the number of front cross rail, center member, after cross member is at least two, keeps being equally spaced, and can make the chassis module holding capacity even.
As preferably, the two ends of said center member exceed the span of two main longitudinal griders and are connected to separately on the auxilliary longeron of both sides.Through increasing the length of center member, can enlarge middle deck, i.e. the area of driving compartment and passenger accommodation.
As preferably; Said upper frame module comprises the master beam of two arches, and the two extends parallel is provided with at least two top camber beams between said two master beams; The front end of said two master beams is fixed with anterior camber beam; This camber beam front portion, front portion is provided with the support vertical beam, and the front end of said two master beams, rear end and middle part are equipped with some support vertical beams, and the bottom of said support vertical beam is fixedly attached on the main longitudinal grider or auxilliary longeron of bottom chassis module.
As preferably, the connection between the said steel pipe is welding.The intensity that is welded as a whole is better, and stability is also better, and processing easily.
The beneficial effect of the utility model vehicle body framework construction is: adopt the steel pipe form to replace traditional steel plate welding structure; Steel pipe skeleton is in light weight; Skeleton adopts crisscross type of attachment simultaneously, can bear higher intensity and load, has not only satisfied the weight-saving requirement but also possess intensity preferably.
