Chassis of an all-aluminum carriage

Abstract

The invention discloses a chassis of a full-aluminum carriage. The chassis of the full-aluminum carriage comprises a bottom edge frame, sub longitudinal beams and transverse beams, wherein the bottom edge frame comprises four edge frame beams which are connected with each other to form a rectangle, wherein the two parallel edge frame beams are transverse edge frame beams; and the other two edge frame beams are longitudinal edge frame beams; at least one the sub longitudinal beam is arranged in the bottom edge frame; the two ends of the sub longitudinal beam are connected with a transverse edge frame beam in an inserted way; at least one transverse beam is arranged in the bottom edge frame; the two ends of the transverse beam are connected with a longitudinal edge frame beam in an inserted way; each transverse beam is connected with each sub longitudinal beam in an inserted way at the crossed part; and the edge frame beams, the sub longitudinal beams and the transverse beams are all made of aluminum alloys. According to the invention, as the beams are connected with each other in an inserted way, the carriage framework forms an integrated structure so that the carriage obtains enough rigidity and strength to satisfy loading requirements. According to the invention, as the sub longitudinal beams are connected with the transverse beams in an inserted way, the end parts of the sub longitudinal beams are inserted in the transverse edge frame beams and the end parts of the transverse beams are inserted in the longitudinal edge frame beams, the chassis forms an integrated structure so that the chassis obtains enough rigidity and strength to satisfy loading requirements of the carriage.

Description

Technical field [0001] The invention relates to the field of carriages, in particular to a chassis of an all-aluminum carriage. Background technique [0002] Aluminum is light in weight, has high corrosion resistance, and is not easy to fade. Products made of aluminum are light in weight and have a long life. In all walks of life, aluminum is increasingly used instead of steel to make products. Especially in the automobile industry, the lightweight of automobiles has become a world development trend. The research report of the World Energy Conservation and Environment Association points out that for every 10% reduction in the weight of automobiles, fuel consumption can be reduced by 6%-8%, and emissions can be reduced by 5%-6. %. Therefore, the lightweight of automobiles is a need for energy saving and environmental protection. [0003] At present, vans such as urban electric logistics vans, in order to achieve the purpose of lightening, mainly realize the lightweight of the carr...
