Abstract

The invention relates to a lightweight total-bearing body frame structure, which comprises a side wall frame, a roof frame, a front wall frame, a rear wall frame and an interlayer frame. The lightweight total-bearing body frame structure is made of an aluminum alloy or magnesium alloy material, and is riveted with lockbolts so as to ensure that the weight of the body frame is greatly reduced while the whole strength of the body is not lower than the conventional steel body frame. The parts forming the body frame has a unique design, so that well balance between weight reduction and strength maintenance can be achieved. The lightweight total-bearing body frame structure saves more energy than the conventional steel frame.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an aluminum alloy or magnesium alloy passenger car frame structure. Background technique [0002] There are three main types of existing passenger car skeleton structures: [0003] The first type is non-load-bearing. The car has a rigid frame, also known as the chassis frame. The main body of the vehicle body is suspended on the vehicle frame and connected by elastic elements, mainly relying on the vehicle frame to bear the load, and the vehicle body does not participate in the force bearing. This kind of non-load-bearing body is relatively cumbersome, high in mass, high in the center of mass of the car, and poor in high-speed driving stability. [0004] The second type is semi-loaded. The car with semi-loaded body does not have a rigid frame, but only strengthens the front wall, side wall, rear wall, chassis and other parts. The body and the chassis together form the ...
