Anti-rollover vehicle and suspension system thereof

Abstract

The invention provides an anti-rollover vehicle and a suspension system thereof, which relate to the technical field of vehicle safety, and have the advantages of simple structure and high reliability. The anti-rollover vehicle comprises a suspension system, including an elastic element and a damping element, and a locking structure for locking a suspension. The locking structure comprises a hydraulic cylinder, including a cylinder body and a piston rod, one of which is connected to a vehicle rack and the other of which is connected to a vehicle wheel. The cylinder body is provided with a rodchamber and a non-rod chamber, communicated through a connection path. The connection path is connected to an energy-storing machine through a control path, and the control path is provided with a control valve for controlling the connection and disconnection. When the vehicle rolls over, the hydraulic cylinder can be controlled. Due to the incompressibility of hydraulic oil, the pressure of hydraulic oil in the hydraulic cylinder can be quickly changed, and the force for resisting the further deformation of the suspension can be generated, and thereby vehicle rollover can be resisted, and safe driving of the vehicle can be ensured.

Description

Technical field [0001] The invention relates to the technical field of automobile safety, and provides an anti-rollover vehicle and a suspension system thereof. Background technique [0002] With the development of modern society, there are more and more means of transportation, but with the growth of vehicles, the number of traffic accidents is also increasing year by year. Among them, the impact of vehicle load or speed and road conditions are the main reasons, especially When large transportation vehicles are turning or encountering road obstacles, traffic accidents caused by their own weight cannot be controlled in time, so in order to ensure that the vehicle is turning or encountering road obstacles and cannot be controlled in time To be safe, technicians set up a suspension system between the frame and the axle to resist the rollover of the vehicle. [0003] In the prior art, the suspension system includes elastic elements and damping elements, which can effectively alleviat...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the suspension system includes elastic elements and damping elements, which can effectively alleviate the impact load transmitted to the vehicle body from the uneven road surface, attenuate the resulting vibration, ensure the comfort of the driver, and reduce the vehicle itself. dynamic load, but the problem is that when the car turns suddenly or receives a lateral force, the body of the vehicle will be subject to a large rollover moment, and only rely on the elastic elements and damping elements in the prior art to passively The angle of the vehicle body is adjusted accurately, and the instant control of the vehicle body cannot be realized, and rollover will still occur, or in the case of emergency steering or increased lateral force, although the suspension system in the prior art will produce anti-side effects on the vehicle. Flip angle, but the improvement effect is limited
