Problems solved by technology
After the oil-gas spring is used for a long time, the temperature of the internal oil will rise, which will lead to an increase in the temperature of the gas. Due to the large thermal expansion coefficient of the gas, the volume of the gas chamber will become larger, which will eventually cause the car body to rise and even change the working of the oil-gas spring itself. characteristics, unable to meet the requirements of use

The invention relates to a modularized adjustable temperature compensation system for hydro-pneumatic suspension. The modularized adjustable temperature compensation system comprises power units, a hydraulic device, a hydro-pneumatic spring, an electric control device, a sensor and the like, wherein the power units supply a power source to the hydraulic device and are connected through a high pressure hard tube or soft tube; the hydraulic device comprises a vehicle gesture adjusting valve block, a compensation control valve block and a compensation hydro-pneumatic cylinder control valve block, wherein the vehicle gesture adjusting valve block is used for adjusting the gesture of a vehicle when the vehicle transiently stops or travels on a flat and straight pavement at a slow speed; the compensation control valve block and the compensation hydro-pneumatic cylinder control valve block are used for adjusting the inflating volume of the hydro-pneumatic spring and a high pressure gas chamber in real time and are used for solving the problem of vehicle gesture change after the temperature of a suspension cylinder rises.
Description
technical field [0001] The invention relates to a compensation oil cylinder control valve group. It belongs to the field of hydraulic machinery and motor vehicle applications. Background technique [0002] The oil-gas spring (hydro-gas spring) uses inert gas as the elastic medium and oil as the damping medium to transmit force and attenuate the impact vibration of the car body. The cylinder has a certain guiding effect and has typical nonlinear working characteristics. [0003] In the prior art, apart from oil-gas springs, the commonly used types of elastic elements mainly include: leaf springs, coil springs, torsion bar springs, rubber springs and gas springs. Leaf springs, helical springs, and torsion bar springs have relatively small energy storage per unit mass, so they can absorb vibration energy to a limited extent while the vehicle is running, and their mass is relatively large; at the same time, the spring stiffness is linear and cannot be adjusted according to the ...
