Abstract

The invention discloses a main load-bearing structure of an automobile chassis made of composite materials, including a car floor and a frame, the frame includes a longitudinal beam and a cross beam, the cross beam includes a front bridge, a middle beam and a rear bridge; the longitudinal beam includes a front section, a middle section and a rear section The front end of the front bridge and the rear end of the longitudinal beam are connected with the anti-collision mechanism connector, the bottom of the front bridge and the rear bridge are connected with the wheel suspension component connector, and the shock absorber connector is installed on the front and rear segments of the longitudinal beam; There is an inner fiber reinforced layer between the bottom surface of the car floor and the longitudinal beams and cross beams; the longitudinal beams and cross beams are semi-closed tubular structures with upper ends open; the longitudinal beams and cross beams are composed of inner fiber layers, intermediate honeycomb structure core layers and outer fiber layers constitute. The invention is made of composite materials, and mainly uses bonding, riveting, and screwing processes to replace traditional steel and welding forging processes. It has the advantages of light weight and high strength, and greatly reduces the amount of steel used. The production cost is saved, and the service life is extended.

Description

technical field [0001] The invention relates to an automobile chassis structure, in particular to a main load-bearing structure of an automobile chassis made of composite materials. Background technique [0002] The main load-bearing structure of the chassis of existing automobiles is mostly made of metal casting or metal plates through forging, punching, welding, or metal pipes. The chassis manufactured by this method has large weight, low strength, and short service life. Large stamping dies and large processing equipment to complete, high production costs. Contents of the invention [0003] The present invention aims to solve the above-mentioned shortcomings, and provides a main load-bearing structure of an automobile chassis made of composite materials. [0004] The above object of the present invention is achieved by the following technical solutions: a main load-bearing structure of an automobile chassis made of composite materials, including a car floor and a skele...
