A traction device based on anti-rollover of liquid tanker and its control method

Abstract

The invention discloses a traction device based on anti-rollover of a liquid tanker and a control method thereof. The hydraulic cylinder is close to the trailer, and the disc groove support device has an inlet and outlet, which will not affect the connection between the trailer and the tractor and when the vehicle is turning, and the free travel of the electronic hydraulic cylinder is set inside the disc groove support device , will not affect the normal bumpy state of the vehicle when it is running; through the control module to monitor the roll angle of the tank truck, when the tank truck is about to roll over, the control module will calculate in real time the amount that the electronic hydraulic cylinder needs to raise according to the roll angle The electronic hydraulic cylinder receives the signal and raises the lifting rod to the accurate height to realize the support of the vehicle, which effectively solves the problem that the existing traction device cannot support the vehicle when the roll angle is too large or too small.

Description

technical field [0001] The invention belongs to the field of semi-trailer liquid tank vehicles, and in particular relates to a traction device and a control method for preventing liquid tank vehicles from tilting and rollover. Background technique [0002] At present, the main ways of transporting hazardous chemicals include sea transport and land transport. Among them, the main carrier of land transportation is liquid tanker. When liquid tank trucks are speeding through corners or emergency avoidance, due to their high center of mass height and large load, major traffic accidents often occur when they roll over. The tank truck has a large size and load capacity, and when it rolls over, it will have a serious impact on the adjacent lanes, resulting in major accidents such as congestion and even serious rear-end collisions with multiple vehicles. In addition, most of the liquid tank trucks are loaded with dangerous chemicals. If leakage occurs during rollover, it will not o...

AI Technical Summary

Problems solved by technology

This method is only to disengage the tractor from the trailer after the vehicle rolls over, so as to avoid personal injury to the driver. Like the above method, it cannot implement active control under the dangerous working conditions that the vehicle is about to roll over or roll.
