The invention discloses a front longitudinal beam assembly structure of an automobile. The front longitudinal beam assembly structure comprises a cross beam, front longitudinal beam front plates symmetrically fixed to the front portions of the left side and the right side of the cross beam and side longitudinal beams symmetrically fixed to the rear portions of the left side and the right side of the cross beam. The rear end of the front longitudinal beam front plate is fixed on the cross beam through a connecting plate, the connecting plate comprises an outer connecting plate and an inner connecting plate, the outer connecting plate and the cross beam are fixed into a whole, the inner connecting plate is used for fixing the front longitudinal beam front plate on the outer connecting plate, and a supporting face used for supporting the front end of the rear longitudinal beam is arranged on the rear portion of the outer connecting plate. The front end of the rear longitudinal beam can be fixed to the supporting face through the transition plate, and the front end of the side longitudinal beam is fixed to the outer side surface of the outer connecting plate. According to the automobile front longitudinal beam assembly structure designed by the invention, the variety of parts is few, the development investment is reduced, the general assembly of the front longitudinal beam front plate, the cross beam and the side longitudinal beams is met, and meanwhile, the number increase and decrease and the position change of the rear longitudinal beams can be carried out in the width direction of an automobile body through an integral mechanism consisting of the transition plate and the general rear longitudinal beams; and the requirements of different vehicle types can be met.

    本发明公开了一种汽车的前纵梁总成结构,包括横梁、对称固定于横梁左右两侧前部的前纵梁前板和对称固定于横梁左右两侧后部的边纵梁;前纵梁前板的后端通过连接板固定于横梁上,连接板包括与横梁固定为一体的外连接板和用于将前纵梁前板固定于外连接板上的内连接板,外连接板的后部设置有用于支撑后纵梁前端的支撑面,后纵梁的前端可通过过渡板固定于支撑面上,边纵梁的前端固定于外连接板的外侧表面上。本发明所设计的汽车前纵梁总成结构的零件种类少,减少了开发投入,满足前纵梁前板、横梁和边纵梁通用性装配的同时,通过过渡板和通用的后纵梁组成的整体机构,可以在车身宽度方向上进行后纵梁的数量增减和位置变化,能适应不同车型的需求。
