Abstract

The invention discloses a wheel beam type axle-free frame manufactured by 3D printing. The wheel beam type axle-free frame comprises connecting support frames, front and rear wheel beam frames, a bottom plate and a car body, wherein the connecting support frames, the front and rear wheel beam frames, the bottom plate and the car body are integrally formed by the 3D printing. The wheel beam type axle-free frame has the advantages that the chassis is integrally manufactured by the 3D printing, welding and riveting are replaced by the 3D printing, and high overall strength and lightness are achieved; lightness is improved favorably, the frame is light, high in strength and rigidity and capable of reasonably bearing all loads, and torque and bending degree can be changed in a controllable range.

Description

technical field [0001] The invention relates to a key supporting part of an automobile, which belongs to the technical field of passenger cars and commercial vehicles, and in particular to a wheel-beam type 3D printed bridgeless frame. Universal bridgeless frame. Background technique [0002] The car driving system is composed of frame, axle, suspension and wheels. The frame is the basic part of the car and an important part of the driving system. The powertrain and chassis of the car are installed facing the frame. The foundation of the carriage should not only have sufficient rigidity, but also have appropriate flexibility, which has a key impact on the performance of the vehicle. The existing automobile frame structure still uses the T-shaped car principle. The front and rear axles are cross-sections, the beams are longitudinal sections, and the frame formed by hinged leaf springs supports and accepts the loads of the chassis and the entire vehicle. The positioning func...
