Round tubes can withstand greater torsional stress, but the section modulus is small, and the non-planar outer surface is difficult to weld
The torsional performance of the angular tube is poor. When the load acting point is not on the center of the bend or the plane of the main axis of the cross section, it is prone to oblique bending and large deformation
The grooved tube has good bending and torsion resistance, and has not been used in energy-saving racing cars.

Abstract
The invention relates to an energy-saving racing car frame, comprising a first lower cross beam, a second lower cross beam, a third lower cross beam, a fourth lower cross beam, a first upper cross beam, a second upper cross beam, a first vertical beam, a second vertical beam, a first vertical post, a second vertical post, a third vertical post, a fourth vertical post, a first support bar, a fourth support bar, a fifth support bar, a sixth support bar, a seventh support bar, an eighth support bar, and a transverse plate.The frame of the invention is a bearing base for energy-saving racing cars, bears the weight of structures such as a driver, an engine, a car body, a steering structure and a braking structure as well as supporting force of wheels and acting force of working load, buffers vehicle impact from a road and the like, and is an important assembly to ensure operational stability and driving safety of a racing car.The energy-saving racing car frame is compact in structure, light in weight and low in cost and has both strength and rigidity meeting the design requirements.
Description
technical field [0001] The vehicle frame of the present invention is a load-bearing base for energy-saving competitive racing cars, which bears the weight of the driver, engine, body, steering structure, etc. energy saving technology. Background technique [0002] Existing energy-saving racing car frames are mostly made of aluminum alloy tubes in order to reduce weight and save energy. Square tube is a cross-sectional shape that is mostly used in racing car frame components. It has better bending and torsion resistance, but has a lower section modulus. Round tubes can withstand greater torsional stress, but have a smaller section modulus, and the non-planar outer surface is difficult to weld. The torsional performance of the angular pipe is poor. When the load acting point is not on the center of the bend or the plane of the main axis of the cross section, it is prone to oblique bending and large deformation. Grooved tubes have good bending and torsion resistance, and hav...
