Steering and suspension integrated anti-roll structure and control method

Abstract

The invention discloses a steering and suspension integrated anti-roll structure, which comprises a hydraulic oil tank, wherein the hydraulic oil tank is connected with an oil pump through a hydraulicpipeline; the oil pump is connected with one end of the hydraulic cylinder via a first main oil way through a channel electromagnetic valve, one end of the hydraulic cylinder is connected with the hydraulic oil tank through a first electromagnetic valve, the oil pump is connected with the other end of the hydraulic cylinder via a second main oil way through the channel electromagnetic valve, andthe other end of the hydraulic cylinder is connected with the hydraulic oil tank through a second electromagnetic valve; and the first main oil way is connected with a first air spring through a fourth electromagnetic valve, the second main oil way is connected with a second air spring through a third electromagnetic valve, and the first air spring is connected with the second air spring through afifth electromagnetic valve. When an automobile steers, the ECU controls on-off of the electromagnetic valve according to sensor information, the volume of the air spring is changed through a steering hydraulic system on the basis of air spring intercommunication, and the anti-roll effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of suspension systems, in particular to a steering and suspension integrated anti-roll structure and a control method. Background technique [0002] As the most used means of transportation, automobiles have been paid more and more attention to their comprehensive performance. Among them, the performance of the suspension is mainly reflected in the comfort of the ride and the stability of the operation. In the prior art, passive suspensions often improve the anti-roll and anti-pitch performance of the vehicle by increasing the stiffness of the suspension or installing a stabilizer bar, but higher suspension stiffness will undoubtedly make the suspension stiffer and damage the The ride comfort of the vehicle; on the contrary, if the suspension with low roll stiffness and pitch stiffness is used, the ride comfort can be improved, but the driving safety of the vehicle under turning and braking conditions canno...

AI Technical Summary

Problems solved by technology

In recent years, some researchers have proposed to change the interconnection state of the air spring in the air suspension to achieve both ride comfort and operational stability of the vehicle. The anti-rolling and anti-pitching performance of the vehicle is improved, but due to the fixed interconnection volume of the elastic elements, the improvement of the vehicle performance is limited
