Problems solved by technology
The air spring has ideal nonlinear elastic characteristics. After installing the height adjustment device, the height of the vehicle body does not change with the increase or decrease of the load. The stiffness of the air spring can be designed to be low, and the ride comfort is good. The stiffness of the existing air spring is fixed. Invariably, in order to pursue ride comfort, the stiffness of the air springs is relatively low, which causes the dynamic travel of the air springs to be too large when the vehicle passes through complex road conditions, and often exceeds the effective travel range. In severe cases, it may even cause the air springs to structural failure

The invention discloses a self-adaptive rigidity adjusting double-chamber air spring which comprises a lifting ring sleeve, an air bag body and a piston cylinder, a first end of the lifting ring sleeve is hermetically mounted on a cover body, a first end of the air bag body is hermetically fixed on the cover body, a second end of the air bag body is fixed at the top of the piston cylinder, and a piston rod is telescopically mounted on the lifting ring sleeve. The lower end of the piston rod penetrates through the piston cylinder and is fixedly connected with the lifting ring seat; a spring seat is arranged in the middle of the sliding barrel, a reset spring is arranged on the upper portion of the spring seat, the top end of the reset spring abuts against the inner side of the cover body, and the bottom end of the reset spring abuts against the top face of the spring seat; an air inlet nozzle communicated with the interior of the air bag body is formed in the cover body. The air spring is provided with the two air cavities, the stability and comfort can be considered, the vibration resisting rigidity can be increased according to the external vibration condition, the air spring can adapt to the external environment in a self-adaptive and staged mode, and the service life of the air spring is prolonged.
Description
technical field [0001] The invention relates to the field of automobile air springs, in particular to a dual-chamber air spring with self-adaptive adjustment stiffness. Background technique [0002] The air spring is filled with compressed air in a sealed container, and uses the compressibility of the gas to achieve its elastic effect, which is generally installed on the rear suspension; For higher requirements, air springs are installed on the car, which are more ergonomic and more comfortable. The air spring has ideal nonlinear elastic characteristics. After the height adjustment device is installed, the body height does not change with the increase or decrease of the load. The air spring stiffness can be designed to be lower, and the riding comfort is good. The stiffness of the existing air spring is fixed. Invariably, in order to pursue riding comfort, the stiffness of the air springs is low, which leads to excessive travel of the air springs when the vehicle passes thr...
