The invention provides a lightweight recreational vehicle chassis frame. The frame includes a bottom frame, the bottom frame comprises: four main beams which are oppositely arranged in parallel in pairs, wherein a rectangular frame is defined by the interiors of the four main beams, the two main beams which are oppositely arranged front and back are main cross beams, the two main beams which are oppositely arranged left and right are main longitudinal beams, a middle auxiliary cross beam is arranged between the main cross beams, at least one front auxiliary cross beam is arranged between the middle auxiliary cross beam and the front main cross beam, and at least two rear auxiliary cross beams are arranged between the middle auxiliary cross beam and the rear main cross beam; a traction frame which is connected with the bottom frame and is integrally positioned below the front part of the bottom frame; an independent suspension beam which comprises an independent suspension cross beam which is arranged outside the middle auxiliary cross beam in a sleeving manner and fixedly connected with the middle auxiliary cross beam, wherein the bottom frame and the traction frame are both made of aluminum alloy, and the single cantilever is made of steel. Compared with an existing traditional steel pipe welding chassis frame, the weight can be reduced by 40% or above, and the safety coefficient can also reach 2.5 when the chassis frame runs on a road surface with the unevenness being the E level.

    本发明提供了一种轻量化房车底盘架,包括底部框架,其包括两两相对平行设置的四根主梁,四根主梁内部围成一个矩形框,其中前、后相对设置的两根主梁为主横梁,左、右相对设置的两根主梁为主纵梁,在主横梁之间设有中部副横梁,在中部副横梁和前部主横梁之间设有至少一根前部副横梁,在中部副横梁和后部主横梁之间设有至少两根后部副横梁;牵引架,与所述底部框架连接且整体位于其前部下方;独悬梁,包括套设在所述中部副横梁的外部并与其固接在一起的独悬横梁;所述底部框架以及牵引架的材质均为铝合金,所述独悬梁的材质为钢。本发明相比现有传统钢管焊接底盘架重量可减少40%以上且在不平度为E级的路面行驶时安全系数也可以达到2.5。
