Problems solved by technology

[0005] The purpose of the present invention is to solve the above-mentioned deficiencies in the background technology and provide a semi-active anti-roll structure and control method. The complexity of the control method leads to a substantial increase in the cost of the suspension structure. Corresponding improvements have been made to reduce the complexity of the stabilizer bar connecting rod structure and change the way the valve group controls the oil. The valve group structure is simpler and the control method is simpler. Simple, and improve the safety of the vehicle

Abstract

The invention relates to the technical field of automobile part structures and control methods, in particular to a semi-active anti-roll structure and a control method. The stabilizer bar connecting rod comprises a piston cylinder body and a liquid storage cylinder communicated with the piston cylinder body through a cross rod, a boss is arranged on the inner wall of the liquid storage cylinder, a flow channel is formed between the boss and the bottom of the cylinder body of the liquid storage cylinder, a containing cavity communicated with the flow channel and the flow channel is formed between the boss and the bottom of the liquid storage cylinder, and a steel ball capable of rolling in the containing cavity is arranged in the containing cavity. Limiting ports for limiting entering of the steel balls are formed in the connecting positions of the two sides of the containing cavity and the channel and the flow channel, gaps for liquid to pass through are reserved between the limiting ports and the steel balls, a through hole for communicating the liquid storage cylinder with the containing cavity is formed in the boss, and the through hole is completely closed when the steel balls move to the end, facing the containing cavity, of the through hole. A set of combined structure of the circulation valve and the compensation valve is designed to control flowing of oil, the rigidity of the stabilizer bar connecting rod is adjusted, and side tipping of a vehicle body is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of auto parts structure and control method, in particular to a semi-active anti-rolling structure and control method. Background technique [0002] With the development of automobile electronic control technology, software-defined automobiles have become the trend of future development. For the field of automobile chassis, active suspension technology is a new trend in the development of future automobile chassis technology. The function of the automobile suspension system is mainly to transmit the interaction force between the vehicle and the road surface, absorb the impact from the road when the car is running, and improve the stability and comfort of the car when driving. [0003] Among them, the anti-roll bar of the automobile can be used to suppress the body roll of the automobile during driving. During the turning of the vehicle, the outside of the vehicle body is tilted due to centrifugal force or th...
