A kind of aluminum alloy air storage tank for vehicle

Abstract

The invention discloses an aluminum alloy air reservoir for a vehicle. The aluminum alloy air reservoir comprises a reservoir body, an end cover, reinforcing ribs and connecting rods, wherein the inner wall of the reservoir body is provided with the plurality of reinforcing ribs along the axis direction of the reservoir body; the bottoms of the reinforcing ribs are connected with the inner wall of the reservoir body, and the tops of the reinforcing ribs extend towards the inside of the reservoir body; rib threaded hole cavities are formed in parts close to the bottoms of the reinforcing ribs and are correspondingly connected with coverthreaded holes in the end cover through the connecting rods; the cross section of each reinforcing rib is boss-shaped, I-shaped or T-shaped; and the connecting rods are bolts, screws or rivets. Due to the adoption of the design, welding seams can be avoided, the pressure resistance and the safety can be improved, the stability of a manufacturing process can be improved, the utilization ratio of a material can be increased, the reject rate can be reduced, and the part manufacturing environment can also be improved.

Description

technical field [0001] The invention relates to an air storage tank, in particular to an aluminum alloy air storage tank for commercial vehicles, and is particularly suitable for providing a gas storage tank capable of eliminating welding seams and having strong pressure resistance. Background technique [0002] At present, with the gradual increase in the lightweight requirements of automobiles, aluminum alloy air storage tanks are more and more widely used, but their manufacturing process is basically the same as that of steel air storage tanks. Finally, welding is performed. This process does not give full play to the advantages of aluminum alloy materials in forming applications. The efficiency is low and the production environment is poor. At the same time, due to the existence of welds, cracks often appear at the welds when the pressure is too high. In addition, due to the instability of welding, there is a certain reject rate, and the material utilization rate is not ...

AI Technical Summary

Problems solved by technology

Although this design reduces the self-weight of the car by using aluminum-magnesium alloy to produce the air storage tank, it still has the following defects: The cover is connected as a whole, and there are many welds. When the pressure is too high, it is easy to crack at the welds, and the pressure resistance is weak.
