Air reservoir adopting composite material

Abstract

The invention relates to an air reservoir adopting a composite material. The air reservoir comprises an inner container, inserts are arranged at the ends of the two sides of the inner container, exhaust pipe connectors and drainage pipe connectors are arranged on the inserts on the two sides, internal drainage pipes are connected to the drainage pipe connectors on the two sides, the tail ends of the internal drainage pipes are connected to the bottommost portion in the inner container, and a fiber resin composite winding layer is arranged on the outer layer of the inner container and comprisesan axial winding layer and a radial winding layer. According to the air reservoir adopting the composite material, full coverage of radial and axial winding of a cylinder body is realized; and in addition, the exhaust pipe connectors and drainage pipe connectors are arranged on the aluminum alloy inserts at the ends, the inserts have good strength as a metal piece, the inserts can further be wrapped by the projection axially wound in the axis direction of the cylinder body, and the safety strength of the two sides of the air reservoir is guaranteed.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a composite material air storage tank. Background technique [0002] Most of the existing vehicle air storage tanks are made of steel or aluminum alloy. The former has a high density and does not conform to the trend of lightweight vehicles, and the interior needs to be treated with surface anti-rust; the latter has a complicated molding process and high manufacturing cost. For metal materials, the material density is still slightly higher. [0003] Existing vehicle air intake drying equipment cannot completely dehumidify, so that after long-term operation of the air storage tank, water will accumulate inside, affecting the work efficiency of the parts and the safety of use in winter, so regular drainage is required. And because of the gravity self-flow reason, the existing air storage tank arranges the drain valve at the bottom of the cylinder body. [0004] Filament windin...

Problems solved by technology

[0005] Although the air storage tanks involved in CN209386002U, CN109253387A and CN107893905A are made of composite materials to achieve partial weight reduction, the water discharge pipe joints are arranged at the bottom of the cylinder body, which interferes with the winding route of the outer layer, so that the winding can only be wound in the radial direction. It does not wrap the end caps on both sides, the strength of the end caps cannot be guaranteed, and the connection strength between the end caps and the cylinder body will also be weak

The disadvantages are: 1. The water discharge hole is located at the bottom of the middle of the barrel, which interferes with the winding route of the outer layer. It cannot be wound axially, and the radial winding cannot strengthen the side of the water discharge hole. It is even necessary to cut the fibers near the water discharge hole to avoid interference. 2. The water discharge hole is close to the welding line of the inner tank, resulting in weakening of the strength near the welding line, and the risk of failure is extremely high; 3. The vent holes on both sides are directly placed on the plastic inner tank, and cannot Reinforced by filament winding, weak at the end cap

[0007] Because the vehicle air reservoir is a safety part directly responsible for vehicle braking, which is related to driving safety, none of the above patents can achieve complete axial and radial winding for the cylinder body, and cannot achieve full coverage, and there are great hidden dangers in terms of safety.
