Problems solved by technology

However, the hydraulic system of the existing device is in working condition during normal work, and it is easy to be damaged if it is used for a long time. When the acceleration and tilt angle are too large, it is easy to cause cylinder explosion, and the safety is not high.

Embodiment 1

[0035] Embodiment 1: When the vehicle is tilted, the roll angle sensor 400 senses the roll angle, and when the LTR is greater than 0.9, the control device 500 controls the suspension system 200 to open, and when the LTR is less than 0.9, it does not open;

Embodiment 2

[0036] Embodiment 2: When the vehicle is tilted, the acceleration sensor 560 senses the tilt acceleration. When the acceleration is greater than 1.2G, the control valve disconnects the pipeline 271 between the two-way hydraulic cylinder 270 and the accumulator 280. Due to the incompressibility of the hydraulic oil, the The pressure of the hydraulic oil in the hydraulic cylinder changes rapidly, thereby generating a force that resists the further deformation of the suspension and resists the rollover of the vehicle. When the acceleration is less than 1.2G, the control valve will not be opened.

Embodiment 3

[0037] Embodiment 3: When the vehicle is tilted, the roll angle sensor 400 senses the roll angle, and the acceleration sensor 560 senses the roll acceleration. When the LTR is greater than 0.9 and the acceleration is greater than 1.2G, the suspension system 200 is opened as the two-way hydraulic cylinder 270 presses and then closes The solenoid valve 272 locks up the pressure, thereby providing better anti-rollover function.

Abstract

The invention belongs to the technical field of automobile safety and especially relates to an anti-rollover integrated control device of a steering coupling active suspension. The device comprises aframe, suspension systems, a wheel frame, a heeling angle sensor and a control device. The suspension systems are installed at four corners of a bottom end of the frame, each suspension system comprises a connecting rod, an elastic element, a damping rod, a shell, a hydraulic rod, a spring, a bidirectional hydraulic cylinder, an energy accumulator and a damping element. The damping rods are movably connected with the hydraulic rods, the bottom ends of the damping rods are connected with the hydraulic rods through the springs, and the hydraulic rods are connected with the bidirectional hydraulic cylinders. According to the anti-rollover integrated control device of the steering coupling active suspension, a better anti-rollover effect can be automatically provided under a condition that a rollover angle and an acceleration of a vehicle are high, pressure of the suspension systems during normal running is reduced, losses and cylinder explosion are reduced, and safety is also improved.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a steering coupling active suspension anti-rollover integrated control device. 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 which the vehicle load or speed is too high and the impact of road conditions are the main reasons, especially When large transport vehicles turn or encounter road obstacles, traffic accidents often occur due to their own weight cannot be controlled in time, so in order to ensure that the vehicle cannot be controlled in time when turning or encountering road obstacles Safety, technicians set up a suspension system between the frame and the axle that can resist the rollover of the vehicle. However, the hydraulic system of the existing device is in working condition during n...
