Abstract

The invention discloses a double-capsule variable stiffness gas spring for an automobile suspension, and relates to the technical field of gas springs. A first oil conveying hole path is longitudinally formed in the inner bottom end of a gas spring inner cylinder, and the first oil conveying hole path is not through on the gas spring inner cylinder; a second oil conveying hole path is formed in the outer bottom end of the gas spring inner cylinder, and the second oil conveying hole path is also not through; a transverse oil conveying hole path is formed in a side surface of the gas spring inner cylinder; the transverse oil conveying hole path communicates the first oil conveying hole path with the second oil conveying hole path; a sealing plug is connected to an outer port of the transverse oil conveying hole path; a blocking sealing plug is connected to an outer port of the second oil conveying hole path, so that the problems that the purposes of absorbing shock and the like are achieved by using transmission change of oil in the conventional gas spring, but when the internal oil is used, the pressure at the conventional oil outlet changes greatly, and an oil sealing structure atthe oil port is common in pressure resistance and is easily damaged are solved.

Description

technical field [0001] The invention relates to the technical field of gas springs, in particular to a double-capsule variable stiffness gas spring for automobile suspension. Background technique [0002] The automobile suspension system refers to a connecting structural system between the body, frame and wheels, and this structural system includes shock absorbers, suspension springs, anti-roll bars, suspension sub-beams, lower control arms, longitudinal rods, Components such as knuckle arms, rubber bushes and connecting rods. When the car is running on the road, it is subject to vibrations and impacts due to changes in the ground. Part of the impact force will be absorbed by the tires, but most of it is absorbed by the suspension device between the tires and the vehicle body. In the automobile suspension system, the oil-gas spring is a suspension elastic damping element with excellent performance. It is the core part of the oil-gas suspension. It has both damping character...
