重型挂车的气制动类型,按其控制方法的不同来分,一般有充气制动和断气制动两种。一、充气制动系统,是将挂车的制动系通过软管与牵引车的制动系联成一体。由于动力气源的供应方法不同,又可分为单管路和双管路两种。1.单管路制动:挂车上不装储气筒,挂车的制动管路与牵引车的管路串联成一个整体。当牵引车的控制阀开启时,同时将压缩空气分配到牵引车和挂车的各车轮制动器气室。这种制动系统的结构虽然较简单,但由于从牵引车流向挂车的管路较长,气流受管道的阻力影响,使前、后轮的制动略有时差,故一般仅适用于半挂车或轮组较少的挂车。2.双管路制动:在挂车上装有一组储气筒,挂车车轮制动器所需的压缩空气由挂车储
Heavy-duty trailer air brake type, according to the different control methods to points, there are generally two kinds of inflatable brake and outage brake. First, the inflatable brake system, is the trailer’s braking system through the hose and tractor braking system into one. Due to different supply methods of power source, it can be divided into two types: single pipe and double pipe. 1. Single-line brake: the trailer is not installed on the gas cylinder, the trailer’s brake line and the tractor’s pipe series into a whole. When the tractor’s control valve is open, compressed air is simultaneously distributed to each wheel brake plenum of the tractor and trailer. Although the structure of this braking system is relatively simple, the flow from the towing vehicle to the trailer is long and the airflow is affected by the resistance of the pipeline, so that the braking of the front and rear wheels is slightly time-lagged. Therefore, the braking system is generally only applicable to the semi-trailer Or fewer trailers trailer. 2. Dual-line brake: the trailer is equipped with a set of gas cylinders, trailer wheel brake required compressed air by the trailer storage
