Abstract

The invention relates to an elastic system and a method for adjusting the height of a vehicle body, the system comprising eight integral hydro-pneumatic separating hydro-pneumatic springs for mountingon eight support points of a vehicle body, each hydro-pneumatic spring being connected with a driving device for performing a vehicle body lifting and lowering action under the drive of the driving device; The driving device comprises an electric motor oil pump group, two speed regulating valves, two synchronous valves, eight hydraulic one-way valves, eight two-position four-way solenoid valves and one two-position three-way solenoid valve. The four-way solenoid valve and the three-way solenoid valve are connected with a control device, and the control device is connected with a control panel; Explosion-proof valve is installed in the oil inlet and outlet of each oil-gas spring; The oil inlet and outlet of each hydro-pneumatic spring are connected with a hydraulic control check valve through a stop valve; Each hydro-pneumatic spring is provided with an angle sensor; A pressure sensor for detecting the pressure in each cylinder block is mounted on the cylinder block of each hydro-pneumatic spring. The invention can realize the height adjustment of a vehicle body, and has the functions of buffering and absorbing vibration energy of a suspension system.

Description

technical field [0001] The invention belongs to the technical field of vehicle suspension systems, and in particular relates to an elastic system and method for adjusting the height of a vehicle body. Background technique [0002] The elastic element is the core component of the suspension system, and the suspension system is an important part of all kinds of land vehicles. The quality of the system has a decisive influence on the handling performance, off-road capability and riding comfort of the vehicle. Therefore, the design and manufacture of elastic elements are critical. Commonly used vehicle elastic elements include leaf springs, coil springs, torsion bar springs, and air springs. Suspension systems for special vehicles and military vehicles that require high mobility often need to have a body height adjustment function, but the above elastic elements cannot meet the requirements. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide...
