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 auto parts structure and control method, in particular to a semi-active anti-roll structure and control method. The stabilizer bar connecting rod includes a piston cylinder and a liquid storage cylinder connected to the piston cylinder through a cross bar. The inner wall of the liquid storage cylinder is provided with a boss, and a flow channel is opened between the boss and the bottom of the liquid storage cylinder. Between the bottom of the liquid storage cylinder, there is an accommodating cavity connecting the flow channel and the passage. Steel balls that can roll in the cavity are arranged in the accommodating cavity, and restrictive steel balls are arranged at the connection between the two sides of the accommodating cavity and the channel and the flow channel. There is a gap for liquid to pass between the limit port and the steel ball, and a through hole connecting the liquid storage cylinder and the accommodating cavity is opened on the boss. One end of the cavity is completely closed. The invention designs a combined structure of a flow valve and a compensating valve to control the flow of oil, adjust the rigidity of the connecting rod of the stabilizer bar, and effectively prevent the roll of the vehicle body.

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...
