The invention provides a frame assembly and engineering machinery, the frame assembly comprises a chassis and an auxiliary frame, the auxiliary frame comprises an auxiliary frame body and an inclined strut, the auxiliary frame body comprises a mounting part, a bottom plate and a vertical plate, the mounting part is in mortise and tenon connection with the vertical plate, the bottom plate is in mortise and tenon connection with the vertical plate, the chassis is relatively fixedly connected with the vertical plate, and the inclined strut is fixedly connected with the chassis. One end of the inclined strut is fixedly connected with the underframe, and the other end of the inclined strut is relatively fixedly connected with the mounting part. According to the frame assembly and the engineering machinery, the auxiliary frame body is changed from an existing whole groove-shaped steel plate or a whole rectangular pipe into the installation part, the vertical plate and the bottom plate, that is, the vertical plate is connected to the bottom plate in a mortise and tenon joint mode, and the installation part used for connecting the bottom frame and the inclined strut is connected to the vertical plate through the mortise and tenon joint structure, so that light weight is achieved, and the service life of the auxiliary frame body is prolonged. The consumption of energy and materials is reduced, and the positions of the chassis and the inclined struts can be conveniently adjusted during assembly so as to realize the connection among the chassis, the auxiliary frame body and the inclined struts; and meanwhile, the machining and assembling precision is also reduced.
本发明提供一种车架总成及工程机械,该车架总成包括底架和副车架,副车架包括副车架本体和斜撑,副车架本体包括安装部、底板和立板,安装部与立板榫卯连接,底板与立板榫卯连接,底架与立板相对固定地连接,斜撑的一端与底架固定连接,斜撑的另一端与安装部相对固定地连接。在本发明的车架总成及工程机械中,副车架本体由现有的整条槽型钢板或整条矩形管构成变更为由安装部、立板和底板组成,即在底板上榫卯连接有立板,立板上通过榫卯结构连接有用于连接底架和斜撑的安装部,既实现了轻量化,降低能源及材料的消耗,又便于在装配时调整底架和斜撑的位置以实现底架、副车架本体和斜撑之间的连接;同时也降低了加工和装配精度。
