The embodiment of the invention relates to the technical field of vehicles, and discloses an auxiliary frame reinforcing structure and a vehicle. The auxiliary frame reinforcing structure comprises a rear reinforcing structure, the rear reinforcing structure comprises a rear reinforcing sleeve and a rear reinforcing part, the rear reinforcing sleeve is used for being connected with a rear mounting part of the auxiliary frame assembly, and the rear reinforcing part is connected with the rear reinforcing sleeve, cabin edge beams and a transverse connecting piece connecting the two cabin edge beams. At least one rear reinforcing cavity is defined by the rear reinforcing component, the engine room edge beam and the transverse connecting piece. According to the rear reinforcing sleeve, the connecting structural strength of the mounting part is better improved, the structural strength of the rear mounting part on the auxiliary frame assembly is improved, the connecting strength between the auxiliary frame assembly and the engine room edge beam is enhanced through the rear reinforcing part, the connecting performance of the auxiliary frame assembly and the vehicle body is improved, and the service life of the auxiliary frame assembly is prolonged. The at least one rear reinforcing cavity can generate effective stress conversion, so that the structural performance of the whole frame and the rigidity of the mounting part of the auxiliary frame can be effectively improved.

    本申请实施例涉及车辆技术领域,公开了一种副车架加强结构及车辆。副车架加强结构包括:后部加强结构,包括后部加强套管和后部加强部件,后部加强套管用于与副车架总成的后安装部连接,后部加强部件与后部加强套管、机舱边梁、连接两个机舱边梁的横向连接件连接,后部加强部件与机舱边梁、横向连接件围成至少一个后加强腔体。本申请提供的后部加强套管更好的提升安装部的连接结构强度,提升后安装部在副车架总成上的结构强度,后部加强部件加强副车架总成和机舱边梁之间的连接强度,提升副车架总成与车身本体的连接性能,至少一个后加强腔体可产生有效的受力转换,可有效提升整个框架的结构性能和副车架的安装部刚度。
