The invention provides a motor train unit body chassis structure, and belongs to the technical field of railway vehicles, the motor train unit body chassis structure comprises a framework assembly and a corrugated bottom plate laid on the framework assembly, the framework assembly comprises two end beams, two side beams, two groups of traction beams, a plurality of cross beams longitudinally distributed at intervals and two groups of in-rail longitudinal beams, the two groups of in-rail longitudinal beams are respectively connected with the two groups of traction beams and extend towards the middle part of the framework assembly; each group of in-rail longitudinal beams comprises two groups of channel beams, the two groups of channel beams are symmetrically distributed at intervals by taking the longitudinal central axis of the framework assembly as a center, one end of each channel beam is fixedly connected with the corresponding traction beam, and the other end of each channel beam extends along the longitudinal direction of the framework assembly and at least crosses over the three cross beams; the channel beam is provided with a wing surface which is attached to and fixedly connected with the corrugated bottom plate, and the transverse width of the wing surface is gradually increased from the traction beam to the extending end of the channel beam. According to the train body chassis structure of the motor train unit, the weight of the chassis can be reduced, and the cost is saved.

    本发明提供了一种动车组车体底架结构,属于轨道车辆技术领域,包括架构总成和铺设于架构总成上的波纹底板,架构总成包括两个端梁、两个边梁、两组牵引梁、纵向间隔分布的多条横梁,以及两组轨内纵梁,两组轨内纵梁分别与两组牵引梁连接并朝向架构总成的中部延伸;每组轨内纵梁均包括两组槽形梁,两组槽形梁以架构总成的纵向中轴线为中心对称且间隔分布,槽形梁的一端与相应的牵引梁固定连接,另一端沿架构总成的纵向延伸并至少跨越三条横梁;其中,槽形梁具有与波纹底板贴合并固定连接的翼面,翼面的横向宽度自牵引梁朝向槽形梁的延伸端逐渐增大。本发明提供的动车组车体底架结构,能够降低底架重量,节约成本。
