High-sealing-performance air spring for automobile

Abstract

The invention discloses a high-sealing-performance air spring for an automobile. The air spring comprises an air spring body, flanges, traction ropes and fastening studs, wherein the flanges are fixedly installed on the upper surface and the lower surface of the air spring body, a connecting groove is formed in the center of each flange, an operation column is installed inside each connecting groove, a positioning groove is formed in the inner wall of each flange, the positioning grooves communicate with the connecting grooves, the outer sides of the bottom ends of the operation columns are fixedly connected to one ends of the traction ropes, the traction ropes penetrate through a fixing shaft and a linear groove to be fixedly connected to the center of a limiting column, and the fixing shaft is fixedly installed inside the bottom ends of the connecting grooves. According to the high-sealing-performance air spring for the automobile, after the fastening studs are screwed into sleeves to be fixedly installed in a threaded mode, the positions of the fastening studs can be fixed through clamping connection of the limiting column and a limiting groove, so that the fastening studs are prevented from rotating and loosening, and the outer side surface of the tail end of the limiting column is of an inclined structure.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an air spring with high sealing performance for automobiles. Background technique [0002] Auto parts are mainly used to assemble and operate various parts of the car, so that the assembly of different parts is beneficial to the overall operation of the car. At the same time, there are various types of auto parts, including automobiles. High-tightness air springs are used, but the existing high-tightness air springs for automobiles still have the following problems; [0003] 1. During the fixed installation process of the high-tightness air spring for automobiles, it is generally fixed directly by external fasteners to achieve a stable work for the high-tightness air spring for automobiles, but subsequent occurrences occur during the operation. Vibration, after long-term use, it is easy to cause loosening of the fasteners connected to each other, which reduces the overall sta...
