The invention relates to the technical field of new energy vehicles and auxiliary frames, in particular to a side beam front auxiliary frame of a non-planar straddle type new energy vehicle. Low-pressure integrated sand core casting is adopted, the weight of the integrated sand core structure is relatively low, the weight reduction amplitude can reach 20-30%, the working procedures are reduced, no welding working procedure exists, and the size is convenient to control. Comprising an upper beam, a lower beam, a left longitudinal beam and a right longitudinal beam, wherein the head end and the tail end of the upper cross beam are each provided with an inclined bent mounting seat, the head end and the tail end of the lower cross beam are each provided with a rear frame connecting seat, a straddle type middle cross beam is arranged between the left longitudinal beam and the right longitudinal beam in the longitudinal direction and stretches across a frame hole, and a central traction rod seat is further arranged in the center of the straddle type middle cross beam. The arrangement plane space position of the straddle type middle cross beam does not coincide with the arrangement plane space of the upper cross beam, a cleat seat is arranged at the T-shaped intersection point position of the left longitudinal beam and the right longitudinal beam in a mode of being matched with the same axis position of the straddle type middle cross beam, and middle suspension installation seats are arranged on the outer sides of the left longitudinal beam and the right longitudinal beam on the lower section of the cleat seat in a shaping mode.
本发明涉及新能源汽车和副车架技术领域,具体为一种非平面跨式新能源车的侧梁前副车架。采用低压一体砂芯铸造,一体砂芯结构重量相对较轻,减重幅度能达到20~30%,减少工序且无焊接工序,尺寸便于管控。包括上横梁、下横梁、左纵梁、右纵梁;其中:所述上横梁的头尾两端各设置一个斜弯安装座,所述下横梁的头尾两端各设置一个后架连接座,所述左纵梁、右纵梁之间纵向横跨框孔设置跨式中横梁,所述跨式中横梁的中央还设置有中央牵引杆座,跨式中横梁的设置平面空间位置不和上横梁设置的平面空间重合,匹配跨式中横梁的同一轴线位置,在左纵梁、右纵梁的T字相交点位置设置羊角座,羊角座下段的左纵梁、右纵梁外侧塑形设置中悬置安装座。
