The invention discloses a front auxiliary frame assembly of an electric passenger vehicle. The front auxiliary frame assembly comprises a front auxiliary frame body lower plate, a front auxiliary frame body upper plate and lining structures assembled on the two sides of the front auxiliary frame assembly. The front auxiliary frame assembly is assembled with a vehicle body through the lining structures. The lining structures are divided into front side lining structures and rear side lining structures; the front side lining structures are integrated on the two sides, close to the front end, of the front auxiliary frame assembly through connecting plates; and the rear side lining structures are integrated on the two sides, close to the rear end, of the front auxiliary frame assembly. According to the front auxiliary frame assembly, the mounting positions of a front lower swing arm, a front stabilizer bar, a steering gear, a front axle rear suspension and a motor lower protection plate are provided, modular assembly can be achieved when the front auxiliary frame assembly is assembled with a vehicle body, and the assembly efficiency is improved; in addition, compared with a shoe-shaped gold ingot type money frame without a bush, the front auxiliary frame assembly has better vibration isolation and vibration filtering performance due to the fact that the front auxiliary frame assembly is arranged on the assembling portion of the vehicle body in a press-fitting mode.

    本发明公开了一种电动乘用车前副车架总成,包括前副车架主体下板、前副车架主体上板、以及装配于所述前副车架总成两侧的衬套结构;所述前副车架总成通过所述衬套结构与车身装配;所述衬套结构分为前侧衬套结构和后侧衬套结构;所述前副车架总成靠近前端的两侧通过连接板集成有所述前侧衬套结构;所述前副车架总成靠近后端的两侧集成有所述后侧衬套结构。本发明的前副车架总成提供了前下摆臂、前稳定杆、转向器、前轴后悬置、电机下护板各自的安装位置,与车身装配时可以实现模块化装配,提高装配效率;另外,与车身装配部位压装衬套,相比无衬套的“元宝”型付钱车架具有更好的隔振、滤震性能。
