Problems solved by technology

[0011] For vehicles with large changes in empty and full load, in order to maintain small changes in vehicle body attitude and ensure vehicle handling stability, it is usually necessary to add a complex adjustment system with a hydraulic source. Although the adjustment accuracy is high, it will increase virtually. product development cost
In addition, for engineering vehicles with explosion-proof requirements, complex adjustment systems will directly lead to a decline in product reliability

Embodiment Construction

[0018] The oil-pneumatic spring with vehicle attitude adjustment function of the present invention is described in detail below in conjunction with accompanying drawing:

[0019] The structure of the high and low pressure air chamber oil-gas spring includes an oil-gas spring actuator 1, a control valve 2, a high-pressure accumulator 3 and a low-pressure accumulator 4.

[0020] The high-pressure accumulator 3 and the low-pressure accumulator 4 are connected with the oil chamber of the cylinder 1 through the control valve 2 . The control valve 2 usually has three states, that is, the state of communicating with the high-pressure accumulator 3, the state of communicating with the low-pressure accumulator 4, and the blocking state of cutting off the oil circuit.

[0021] For the situation that the vehicle has N types of loads, N (N is a natural number, N≥2) accumulators with the same pressure as the load can be added, and they are respectively connected to the control valve 2. At ...

Abstract

The invention provides an oil-gas spring with the function of regulating vehicle pose, comprising an actuation cylinder, a control valve and N energy accumulators, each pressure of the N energy accumulators is equal to load, the oil-gas spring can realize slight change of the vehicle pose when the vehicle is in empty full-load state under the condition that the regulating system of vehicle pose isnot added.

Description

technical field [0001] The invention relates to an oil-pneumatic spring system with a vehicle attitude adjustment function for adjusting and maintaining a constant vehicle height from the ground. It belongs to the field of hydraulic machinery and motor vehicle applications. Background technique [0002] Suspension is the general term for all force transmission connection devices between the frame (or load-bearing body) and the axle (or wheel). In a popular sense, the suspension system is composed of elastic elements, damping elements and guiding devices. Of course, in terms of specific structural realization, the above-mentioned components may not all appear in an independent form. [0003] In recent years, the development of oil and gas springs has made great progress, and has been used in some engineering vehicles and military vehicles. Compared with traditional elastic components, oil and gas springs generally have the following characteristics: [0004] (1) Nonlinear ...
