Lift axle control valve
Abstract:
A lift axle control valve (200) for controlling a vehicle lift axle is provided. The valve (200) includes a vehicle port (103) configured to receive a vehicle pressure and a suspension port (106) configured to receive a suspension pressure. The valve (200) is configured to receive a lift axle control signal, actuate the lift axle control valve (200) to connect one or more lift bag output ports (121) to the vehicle port (103) and to connect one or more load bag output ports (131) to the vent port (118) if the lift axle control signal comprises a lift command, and actuate the lift axle control valve (200) to connect the one or more load bag output ports (131) to the suspension port (106) and connect the one or more lift bag output ports (121) to the vent port (118) if the lift axle control signal comprises a load command.
Abstract(Chinese):

提供一种用于控制车辆起重轴的升降机轴控制阀（200）。 阀（200）包括构造成接收车辆压力的车辆端口（103）和构造成接收悬架压力的悬挂端口（106）。 阀（200）被配置为接收升程车轴控制信号，致动升降车轴控制阀（200）以将一个或多个提升袋输出端口（121）连接到车辆端口（103）并且连接一个或多个负载 如果提升车轴控制信号包括提升命令，并且启动提升轴控制阀（200）将一个或多个装载袋输出端口（131）连接到悬架上，则袋输出端口（131）到排气口（118） 端口（106），并且如果提升轴控制信号包括负载命令，则将一个或多个提升袋输出端口（121）连接到排气口（118）。
