Move into the pile, fill the bucket and lift. Back up and turn at the same time. Then accelerate, brake again in front of the dump truck and empty the bucket – that’s the daily routine of a wheel loader. BODAS shifts the gears for maximum acceleration and controls the travel drive to minimize fuel consumption. After all, unloading and reloading has to be as fast and efficient as possible.
In order to carry out these functions, a whole series of software packages work together in the BODAS controller. They include control of switching operations on the mechanical power shift gear with no interruption of tractive force, based on the gas pedal position and direction selection. The input variables for this are supplied by BODAS angle and speed sensors.
The drive control and load limiting control modules ensure that the hydraulics provide optimum conversion of the diesel engine output. The coordinated hydraulic pumps and motors are adjusted for travel drive and additional functions. As soon as the loader drops to part-load operation, the eco-drive reduces the diesel engine speed to save fuel. BODAS temperature sensors working alongside the fan control software module provide optimum engine cooling.
The electronic boom control makes moving a full bucket much easier. This ensures that the bucket position remains horizontal, regardless of the height of lift.
