ABS(Anti-lock BrakingSystem)防抱死制动系统,通过安装在车轮上的传感器发出车轮将被抱死的信号,控制器指令调节器降低该车轮制动缸的油压,减小制动力矩,经一定时间后,再恢复原有的油压,不断的这样循环(每秒可达5-10次),始终使车轮处于转动状态而又有最大的制动力矩。没有安装ABS的汽车,在行驶中如果用力踩下制动踏板,车轮转速会急速降低,当制动力超过车轮与地面的摩擦力时,车轮就会被抱死,完全抱死的车轮会使轮胎与地面的摩擦力下降。如果前轮被抱死,驾驶员就无法控制车辆的行驶方向;如果后轮被抱死,就极容易出现侧滑现象。装有ABS的车辆在遇到积雪、冰冻或雨天等打滑路面时,可放心的操纵方向盘,进行制动。它不仅有效的防止了事故的发生,还能减少对轮胎的摩损,但它并不能使汽车缩短制动距离,在某些情况下反而会有所增加。
ABS (Anti-lock BrakingSystem) anti-lock brake system, the sensor mounted on the wheel sends a signal that the wheels will be locked, and the controller commands the regulator to reduce the wheel cylinder hydraulic pressure to reduce the braking torque , After a certain period of time, and then restore the original hydraulic pressure, such a continuous cycle (up to 5-10 times per second), always make the wheels in rotation and maximum braking torque. If you do not install the ABS car, if you press hard on the brake pedal while driving, the wheel speed will decrease rapidly. When the braking force exceeds the friction between the wheel and the ground, the wheel will be locked and the completely locked wheel will make the tire Friction with the ground down. If the front wheel is locked, the driver can not control the vehicle’s driving direction; if the rear wheel is locked, it is very prone to skidding phenomenon. ABS equipped vehicles in the face of snow, ice or slipping on the rainy road, you can rest assured steering wheel for braking. It not only effectively prevented the accident, but also reduced the tire wear and tear, but it does not make the car shorten the braking distance, but in some cases it will increase.
