Problems solved by technology
[0004] At present, the oil-gas spring technology mainly includes three types, the first is oil-gas separation, the second is oil-gas mixing, and the third is liquid-liquid. These three structures, the oil-gas separation technology is to use the piston to divide the cylinder into two cavities. , one cavity is gas, the other cavity is liquid, and the compressibility of gas is used for buffering; the oil-gas mixing technology uses the characteristics of oil and gas for throttling and damping for buffering; the third is liquid-liquid, that is, in There is liquid at both ends of the piston, and the liquid flow resistance is used for buffering. None of these three technologies can achieve rotation, and can effectively absorb the impact pressure and pulsating pressure caused by uneven road surfaces, which cannot meet the effective control of large and heavy-duty vehicles.

Embodiment Construction
[0021] A rotary oil-pneumatic spring of the present invention will be further described in detail in conjunction with the accompanying drawings and examples. As shown in the figure, a rotary oil-pneumatic spring of the present invention is integrated with multiple components to form a rotatable buffer device. The operation steps as follows:
[0022] Step 1, open the filling and deflation valve 4 to inflate, and the inner cylinder 11 drives the upper lug 3 to retract together; Step 2, open the oil port 15 to fill the liquid, so that the upper lug 3 extends to the full stroke and installed on the upper and lower connectors; Step 3, rotate the upper and lower connectors, the upper lug 3 can rotate 360 degrees around the central axis continuously; when there is vibration or impact on the upper and lower connections, the inner cylinder The cylinder 11 floats up and down in the outer cylinder 12 by utilizing the flow resistance of the oil to realize non-linear damping; the pressur...

The invention discloses a rotating hydro-pneumatic spring. A rotatable buffer device is formed. The rotating hydro-pneumatic spring is characterized in that an upper support lug can continuously rotate around a central shaft by 360 degrees; an inner cylinder barrel floats up and down in an outer cylinder barrel through the flowing resistance of oil, and nonlinear damping is achieved; a pressure valve is arranged in the inner cylinder barrel, and accurate movement and force transmission are achieved through the incompressibility of the oil; various high-power control is realized by utilizing the controllability of oil flowing, and the rotating hydro-pneumatic spring has the characteristics of nonlinearity and gradual increase or decrease; and impact pressure and pulsating pressure generatedby the system due to dramatic flow change can be absorbed.
Description
Technical field: [0001] The technology relates to the technical field of vehicle oil-pneumatic suspension, in particular to a rotating oil-pneumatic spring technology. Background technique: [0002] In the field of large-scale construction machinery, vehicles are an important tool of modern engineering technology. Their maneuverability, driving speed, ride comfort, lateral stability, cushioning reliability and ride comfort are several important indicators of their maneuverability. In the development and improvement of vehicle technology, the vehicle needs to complete the slewing operation in a small area or space in many occasions, which cannot be realized in the existing technology. [0003] The riding comfort of a vehicle is related to the inherent vibration characteristics of the body, which is closely related to the characteristics of the suspension. The suspension is all the force transmission connection devices between the frame or load-bearing body and the axle or whe...
