Multifunctional hydraulic interconnected suspension system

Abstract

A multifunctional hydraulic interconnection suspension system, related to the field of automobile technology, including a left hydraulic cylinder, a right hydraulic cylinder, a first connecting pipe, a second connecting pipe, a third connecting pipe, a fourth connecting pipe, synchronization, etc. Quantity converter, steering gear, sensing device, hydraulic pump and oil tank; the first connecting pipe is connected between the upper connecting ports of the left hydraulic cylinder, the second connecting pipe is connected between the lower connecting ports of the right hydraulic cylinder, and the third The connecting pipes are cross-connected between the left and right hydraulic cylinders located at the opposite corners, one end of the fourth connecting pipe is connected to the third connecting pipe and the other end is connected to the synchronous equivalent converter, and the steering gear passes through the pipe It is connected with the synchronous equivalent converter, the induction device is connected with the steering gear, and the first connecting pipe and the second connecting pipe are respectively connected with the synchronous equivalent converter through pipelines. Not too bumpy, anti-rolling, active adjustment of stiffness, automatic control of vehicle balance, sensitive response, good stability and comfort.

Description

[0001] Technical field: [0002] The invention relates to the technical field of automobiles, in particular to a multifunctional hydraulic interconnection suspension system. [0003] Background technique: [0004] Vehicle rollover accidents cause serious casualties and are a global issue related to public health and safety. According to incomplete statistics, rollover accidents in China cause more than 6,000 deaths every year, causing immeasurable economic losses. Reducing the incidence of rollover accidents has become a top priority social problem. Existing vehicles are dealing with rollover and pitching. The technology is still in the stage of exploration, and the technology is quite simple. When driving fast on the corresponding level road, if there is an emergency and you need to make a sharp turn to avoid an emergency, or you need to make a turn, it will easily lead to roll or front and rear pitching. It even leads to a rollover accident. When driving on uneven roads, it ...

According to incomplete statistics, rollover accidents in China cause more than 6,000 deaths every year, causing immeasurable economic losses. Reducing the incidence of rollover accidents has become a top priority social problem. Existing vehicles are dealing with rollover and pitching. The technology is still in the stage of exploration, and the technology is quite simple. When driving fast on the corresponding level road, if there is an emergency and you need to make a sharp turn to avoid an emergency, or you need to make a turn, it will easily lead to roll or front and rear pitching. It even leads to a rollover accident. When driving on uneven roads, it has great limitations. It cannot be quickly overturned, otherwise it will be damaged. The impact of a single wheel or a single set of wheels due to uneven roads during travel is generally It is borne by a single or single set of wheels, so for a single or single set of wheels, the impact force is relatively large, the vibration is relatively large, and it is more likely to be damaged. The change in the height of the wheel will basically not affect the height of other wheels, so the car body is more prone to large inclinations and even rollovers.

Moreover, in the existing vehicle active suspension control system, both anti-torsion and anti-roll control control the lifting of a single suspension or increase the stiffness. ECU and various electronic control components are used to control the lifting and stiffness of each single suspension. Higher vehicle manufacturing costs
