Problems solved by technology
Although the shock absorber of this structure realizes the separation of oil and gas and solves the problem of lost motion to a certain extent, because it is an external structure, it takes up a lot of space and is limited by space during assembly, so it is not convenient to be directly used on the car suspension. , with limited scope
And because there are many parts and high cost, the joints of each part are not sealed reliably, and the problems of leakage, oil and gas are prone to occur. The pressure of the high-pressure air chamber in the cylinder should not be too high (generally between 5 and 8 atmospheres) , so its response sensitivity under high-speed working conditions and low-temperature conditions is also very limited

An oil-gas separated hydraulic shock-absorber for automotive vehicles includes a piston connecting-rod, an oil-storage barrel, a work cylinder disposed between the internal guide seat and compression valve of the oil-storage barrel, a reset valve mounted at the bottom of the piston connecting-rod and located in the work cylinder, a bottom valve seat mounted on the inner wall of the oil-storage barrel, a floating piston disposed in the cavity under the bottom valve seat and Y-shape seal rings sleeved on the floating piston.
Description
technical field [0001] The invention belongs to the technical field of motor vehicle suspension, and in particular relates to a shock absorber of a motor vehicle. Background technique [0002] At present, hydraulic shock absorbers for motor vehicles, especially automobiles, usually have a double-barrel structure, that is, a working cylinder and an oil storage cylinder. The working cylinder is located in the oil storage cylinder. It is installed at the lower end of the piston connecting rod and is located in the working cylinder. The hydraulic shock absorber of the existing double cylinder structure is usually a pure oil pressure type or an oil-gas hybrid type. The oil storage tank cavity of the pure hydraulic shock absorber cannot be filled with shock absorber oil, and a certain space needs to be left, otherwise the connecting rod cannot move, so there is air in the oil storage tank, and the oil storage tank cavity The pressure of the medium shock absorber oil is low (clos...
