Hydraulic interconnected suspension system for preventing pitching and rolling from crossing, lifting and twisting

Abstract

The hydraulic interconnected suspension system for preventing pitching and rolling from crossing, lifting and twisting relates to the technical field of automotive suspension, comprising a hydraulic cylinder and a shock absorber. The hydraulic cylinder is arranged on the upper side of an automotive wheel. Two hydraulic cylinders are arranged on the upper side of each automotive wheel. The lower part of the two hydraulic cylinders on the same end of the different wheels is connected through a first pipeline, and the upper part is connected through a second pipeline. The lower part of the rest hydraulic cylinders on the same side of the different wheels is respectively connected with the lower part of the rest hydraulic cylinders on the other end of the different wheels through a third pipeline, and the upper part is connected through a fourth pipeline. The shock absorber is connected among the first pipeline, the second pipeline, the third pipeline and the fourth pipeline. The hydraulic interconnected suspension system for preventing pitching and rolling from crossing, lifting and twisting has the advantages of being stable in automotive running, uniform in force of the automotive body, wide in application range, capable of controlling the automotive overall body lift, omnibearing and better in prevention of pitching and rolling function, and favorable for improving the comfort and safety of the vehicle.

Description

[0001] Technical field: [0002] The invention relates to the technical field of automobile suspensions, in particular to a hydraulically interconnected suspension system for realizing anti-pitching, anti-rolling, cross-lifting, and torsion elimination. [0003] Background technique: [0004] According to foreign statistics, vehicle rollover is one of the important causes of casualties, especially on the roads of flying cities. Such accidents account for 54% of the casualties of rural members and 44% of white-collar members, second only to the losses caused by collision accidents. In some foreign countries, there are special strict laws and regulations formulated to deal with rollover accidents. Existing vehicles are still in the groping stage in terms of technology to deal with roll and pitch, and the technology is quite single.

Problems solved by technology

Existing vehicles are still in the groping stage in terms of technology to deal with roll and pitch, and the technology is quite single. When the vehicle accelerates or brakes in an emergency, there will often be an effect of raising the head and nodding the latter, which will affect the longitudinal driving of the vehicle. Comfort will have a negative impact on the front axle composite and suspension elastic components. When driving fast on a corresponding level road, if you encounter an emergency and brake suddenly or need to turn sharply to dodge or make an emergency brake to turn, it will easily cause side effects. Tilting or pitching back and forth can even lead to rollover accidents. When driving on uneven roads, it has great limitations and cannot be quickly overturned, otherwise it will be damaged. The impact of a single wheel or a single set of wheels due to uneven road surface during driving The force is generally borne by a single or single set of wheels, so for a single or single set of wheels, the impact force is greater, the vibration is relatively large, and it is more likely to be damaged. A single or single set of wheels is impacted due to The height amplitude change produced by the shock absorbing device will basically not affect the height of other wheels, so the car body is more prone to large tilts and even rollovers.
