Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile, especially a drying tank. BACKGROUND

[0002] A commonly used drying tank structure for air suspension system is formed by connecting an upper shell and a lower shell through flanges and fastening by corresponding bolts and hot-insert nuts, and a sealing gasket is arranged in the middle of the upper and lower shells. The tank body is provided with a venting circular hole at each end, and the tank body is filled with a material for drying gas. The upper and lower shells of the drying tank structure are injection molded from polyamide material filled with modified glass fiber, and the sealing gasket is made of rubber material and can tightly adhere to the two sides under the extrusion of the upper and lower shells. The hot-insert nuts are placed in the injection mold and tightly adhere to the inner hole after injection molding. The bolts lock the upper and lower shells during installation.

[0003] However, the overall structure of the drying tank requires a large working pressure. Due to space limitations, only three flange bolts are used for fixation. Under the action of high pressure in the tank body, the upper and lower shell bodies at the flange position produce a large axial deformation, resulting in a failure to achieve sealing effect in the area between the two bolts. The flange surface made of resin material deforms easily due to the high working pressure of the current structure. Resin has much weaker strength than steel and other materials. In the limited space, the resin structure will have to be reinforced with a large number of reinforcing ribs. The large wall thickness still does not meet the requirements, and the resin-based structure will also face shrinkage deformation, anisotropic distribution of materials, and other factors during injection molding.
