Abstract
The invention relates to the technical field of automobile suspensions, in particular to a lifting oil cylinder of an oil gas suspension system. Comprising a three-stage nested piston mechanism, an active exhaust oil supplementing mechanism, a self-adaptive adjusting mechanism and a self-sealing mechanism. According to the invention, through the cooperation of the three-stage nested piston mechanism and the high-precision displacement sensor, the high-precision control of the lifting height of + / -0.2 mm can be realized, so that the high-precision control required by precision operation can be met; the active exhausting and oil supplementing system can exhaust gas in the oil cylinder and supplement oil liquid in time, the problem of slow action caused by gas mixing and oil liquid insufficiency is avoided, and the operation efficiency is improved by more than 40%; the self-adaptive adjusting mechanism can automatically adjust the working parameters of the oil cylinder according to the real-time working condition of the vehicle, the adaptive capacity of the oil cylinder under the complex working condition is enhanced, faults are reduced, and the reliability of the oil cylinder is improved.
