Modularized vehicle position regulating system

Abstract

The invention relates to a modularized vehicle position regulating system which regulates the position of a vehicle, and consists of a system power source, a hydraulic device, an oil gas suspension, an electric control unit and a sensor, wherein the system power source, the hydraulic device and the oil gas suspension are connected together through a pipeline, the oil gas suspension comprises at least two left oil gas suspensions and at least two right oil gas suspensions, the hydraulic device comprises a suspension device control combination and a communication hydraulic lock combination, the communication hydraulic lock combination is used for realizing the functions of suspension balancing and hydraulic locking, the suspension device control combination mainly comprises an overflow valve, an unloading valve, a suspension control valve, a right suspension hydraulic lock, a left suspension hydraulic lock, a right throttle valve set and a left throttle valve set, and the overflow valve and the unloading valve are connected in parallel; and an oil outlet end b of the unloading valve is respectively connected with the oil inlet ends of a front suspension control valve and a rear suspension control valve through the pipeline, and the oil outlet ends of the front suspension control valve and the rear suspension control valve are sequentially connected with the throttle valve sets and the suspension hydraulic locks in series.

Description

technical field [0001] The invention relates to a modular vehicle attitude adjustment system for a vehicle using an oil-gas spring, belonging to the application fields of hydraulic machinery and motor vehicles. Background technique [0002] In the prior art, the stiffness characteristics of the elastic elements of the traditional suspension are not adjustable, and the vehicle body posture will change significantly when the vehicle load changes greatly, resulting in a significant decrease in the handling stability and ride comfort of the vehicle. In some cases, foreign companies have realized two-stage stiffness-adjustable suspension forms with no-load and full-load through oil and gas springs, but there are not only two states in the actual use of the vehicle, and the uncertainty of the load makes this adjustment method unable to meet the use requirements. , which has also become a technical difficulty that domestic vehicle manufacturers are facing and cannot effectively sol...

Problems solved by technology

[0002] In the prior art, the stiffness characteristics of the elastic elements of the traditional suspension are not adjustable, and the posture of the vehicle body will change significantly when the vehicle load changes greatly, resulting in a significant decline in the vehicle's handling performance and ride comfort. In this case, foreign companies have realized a two-stage stiffness-adjustable suspension with no-load and full-load through oil-pneumatic springs, but there are not only two states in the actual use of the vehicle, and the uncertainty of the load makes this adjustment method unable to meet the use requirements. , which has also become a technical difficulty faced by domestic vehicle manufacturers and has not been able to effectively solve it, so it is particularly necessary to develop a suspension system with continuously adjustable vehicle posture.
