Embodiment Construction
[0037] In order to make this structural scheme clearer, this paper uses a 6.84-meter fully-loaded pure electric mid-bus chassis structure as a specific description:
[0038] A general-purpose pure electric passenger car underframe structure, the underframe is a truss structure welded by rectangular steel pipes, which includes a front section 1 of the underframe, a middle section 2 of the underframe, and a rear section 3 of the underframe connected in sequence along the front and rear directions.
[0039] The underframe front section 1 includes three horizontal truss structures connected to each other and parallel to the yoz coordinate plane of the vehicle body coordinate system and the front axle.
[0040] The middle section 2 of the underframe is composed of longitudinal trusses I4, longitudinal trusses II5, longitudinal trusses III6, longitudinal trusses VI7, and transverse trusses I8, transverse trusses II9, transverse trusses III10, and transverse trusses VI11 parallel to t...
