MILLING MACHINE HAVING A VALVE CURRENT BASED HEIGHT MEASUREMENT SYSTEM
A milling machine may have a frame, a milling drum attached to the frame, and ground engaging tracks that support the frame and propel the milling machine in a forward or rearward direction. The milling machine may have height adjustable actuators connecting the frame to the tracks. Each actuator may have a cylinder attached to the frame, a piston slidably disposed within the cylinder, and a rod connected at a first end to the piston and connected to a track at a second end. The milling machine may have a tank storing hydraulic fluid and a fluid conduit connecting the tank to the cylinder. The milling machine may have a control valve selectively controlling a flow rate of the hydraulic fluid in the fluid conduit. The milling machine may also have a controller that determines a height of the frame relative to the ground surface based on the flow rate.
一种铣刨机，其可具有框架、附接到框架的铣刨鼓以及地面接合履带，地面接合履带支承框架且沿向前或向后方向推进铣刨机。铣刨机可以具有将框架连接到履带的高度可调节致动器。每个致动器可具有附接到框架的缸，可滑动地设置在缸内的活塞，以及杆，所述杆在第一端处连接到活塞且在第二端处连接到履带。铣刨机可具有储存液压流体的储罐和将储罐连接到缸的流体导管。铣刨机可具有选择性地控制流体导管中的液压流体的流速的控制阀。铣刨机还可以具有控制器，控制器基于流速确定框架相对于地面表面的高度。
