The invention relates to a follow-up bridge differential lock circuit control method, and solves the problem that the state of a follow-up bridge locking cylinder is controlled by adopting a rocker switch at present. In the low-speed running mode, when the vehicle runs at a low speed, namely the vehicle speed is smaller than or equal to 30 Km/h, a vehicle body controller controls a follow-up axle locking electromagnetic valve to work, and a locking cylinder on a follow-up axle is in a free state under the action of air pressure; 2, in a high-speed driving mode, when the vehicle body controller analyzes that a vehicle speed message is greater than 30Km/h, a follow-up axle locking cylinder is in a locking state, so that the problem that the vehicle drifts due to the fact that the follow-up axle swings severely and cannot be controlled when the vehicle runs at a high speed is effectively avoided; and 3, in a reversing mode, when the automobile body controller receives a reversing signal, the pins of the automobile body controller can output voltage to control the relay to start working no matter how high the automobile speed is, and the follow-up axle locking cylinder is in a locking state to ensure that the follow-up axle runs along a straight line. According to the method, the problem that the follow-up bridge is damaged due to human factors can be effectively avoided.
本发明涉及一种随动桥差速锁电路控制方法,解决了目前采用翘板开关控制随动桥闭锁缸的状态存在的问题。1、低速行驶模式:在车辆低速行驶即车速小于等于30Km/h时,车身控制器控制随动桥闭锁电磁阀工作,随动桥上的闭锁缸在气压的作用下处于自由状态;2、高速行驶模式:当车身控制器解析到车速报文大于30Km/h时,随动桥锁止缸处于锁止状态,有效避免车辆高速行驶时,随动桥方向剧烈摆动无法操控导致的车辆发生甩尾问题;3、倒车模式:当车身控制器接收到倒车信号时,无论车速是多少,车身控制器针脚都会输出电压控制继电器开始工作,随动桥锁止缸处于锁止状态,保证随动桥沿直线行驶。本发明方法可以有效避免人为因素导致随动桥损坏问题的发生。
