The invention relates to the technical field of new energy vehicles and auxiliary frames, in particular to a front auxiliary frame of a straddle type center sill new energy vehicle. Different installation positions are arranged by adopting a middle cross beam separation structure, the size of the whole front auxiliary frame is compactly compressed, and a connecting and fixing structure is reasonably arranged, so that a hybrid engine and a gearbox are installed. Comprising an upper cross beam, a lower cross beam, a left longitudinal beam and a right longitudinal beam which are integrally cast to form a frame-shaped structure surrounded by a low-pressure integrated hollow pipe body; a middle seat beam is transversely arranged in the frame hole and divides the frame hole into a main frame hole for erecting an engine and an auxiliary frame hole for erecting a gearbox, and a middle fixing seat for fixing the head and tail structures of the engine and the gearbox is arranged in the center of the middle seat beam. The left longitudinal beam and the right longitudinal beam are consistent in structure, a claw seat is arranged, and a lower swing arm seat is arranged beside the claw seat; a front inclined seat which is obliquely arranged is arranged at the joint of the head end and the tail end of the upper cross beam and the left longitudinal beam or the right longitudinal beam; and the front inclined seat is divided into a claw tube seat stand and a front swing arm seat stand.

    本发明涉及新能源汽车和副车架技术领域,具体为一种跨式中梁新能源车的前副车架。采用中横梁分隔的结构设置不同的安装位置,紧凑压缩整个前副车架体积,合理安排连接和固定结构,让混动引擎和变速箱进行安装。包括上横梁、下横梁、左纵梁、右纵梁,四者一体铸造成低压一体中空的管体围绕成的框形构造;其中框孔中横向设置有中座梁,中座梁将框孔分隔为分别架设引擎的主框孔和架设变速箱的副框孔,中座梁中央设置有固定引擎和变速箱头尾结构用的中固定座;左纵梁、右纵梁结构一致,在设置羊角座,羊角座旁侧设置下摆臂座;在上横梁的头尾两端和左纵梁或右纵梁连接处设置有斜向设置的前斜座,前斜座一分为二设置羊角管座台和前摆臂座台。
