Definitions
- the invention relates to a method for regulating, in particular, the swivel device a mobile machine, in particular a construction machine, such as one Hydraulic excavator or dgL acc. generic part of the first claim.
- a measure to avoid exceeding the permissible maximum speed is due to the fact that the speed of the Drive motor before the braking process is initiated by a predeterminable speed is lowered. In large hydraulic excavators, however, this leads to the drive motor not sufficient for other motion sequences, such as lifting the boom Performance can bring more, so that here too the economy of the construction machine is questioned.
- JP-A 03 219 167 discloses a closed hydraulic circuit for construction machines, with a drive motor, a hydraulic pump and a hydraulic motor. in the closed hydraulic circuit there is a changeover valve, which via lines with the main lines between the hydraulic pump and hydraulic motor connected is. There are also means for controlling the switching process provided that when a predetermined speed of the Drive the switching valve in a connection position with the two Main lines switches.
- the drive motor of which is on the hydraulic motor and the hydraulic pump on the same supporting load is separated and can therefore be reduced again Speed ranges are reduced.
- the load would form a rotating superstructure of a hydraulic excavator Swing it further after the uppercarriage has been separated from the drive motor and should have additional elements, e.g. B. a mechanical brake, be slowed down.
- This prior art therefore only affects Regulation of a drive motor, however, regardless of the focus on it supporting load.
- the object of the invention is that Maintaining the overall economy of the mobile machine, especially the construction machine, the full power of the drive motor when Braking masses, such as B. an uppercarriage can be used can without exceeding the maximum speed of the drive motor.
- a valve can be triggered when the specified speed is exceeded are switched so that one or more main pumps against one Have to promote pressure relief valve.
- This solution is against the first one however, to be rated as subordinate, since structural changes to the hydraulic system must be made and, in addition, an additional Heat generation in the hydraulic system.
- the braking torque, in particular the swivel hydraulics, is thus initiated by this additional energy is heated in the hydraulic system.
- the swivel pumps, the main pumps and the drive motor, especially the Diesel engine, are via a transmission, especially a pump transfer case mechanically connected.
- a transmission especially a pump transfer case mechanically connected.
- a diesel engine 1 designed as a drive engine can be seen, which has a Pump transfer case 2 is connected to a hydraulic pump 3.
- the Hydraulic pump 3 feeds a hydraulic motor 4.
- the hydraulic pump 3 and the Hydraulic motor 4 are operated in a closed swing circle 5.
- the performance of the Hydraulic motor 4 is connected to a mass 7 via a swivel gear 6 here a superstructure of the construction machine, not shown.
- About one in the Cabin of the construction machine provided hand lever 8 is hydraulic Pilot control 9 of the swivel angle 3 'of the hydraulic pump 3 changed.
- the inventive solution shown in Fig. 1 includes an electrical Feedforward control 10 which u. a. includes electronic components 11, 12.
- the component 11 is in this example for the target - actual comparison of the nominal and limit speed of the Diesel engine 1 is provided while the component 12 is a control element which when the specified speed is exceeded on the swivel hydraulics acting pilot current is reduced. This reduces the brake pressure of the closed one Swing circle 5 and thus the support torque on the diesel engine 1.
- Das Control element 12 overrides what interacts with the hand lever 8 Control element 13 or its current delivery, so that when braking the mass 7 critical speed of the diesel engine 1 in no case - not even when unwanted incorrect operation of the hand lever 8 by the operator - is exceeded.
- FIG. 2 shows a further variant of the regulation of a likewise according to the invention Swing circle of a construction machine, not shown.
- the electronic Pilot control 10 includes electronic components 11' as well as 12 'analogous to FIG. 1, wherein the component 11 'for the target - actual - comparison of the nominal and limit speed of the Diesel engine 1 is responsible. If the specified speed is exceeded, in particular the critical limit speed, is not a via the control element 12 ' further shown valve switched so that at least one main pump 14 against Pressure relief valve 15 must promote.
- the swivel pump 3, the main pump 15 and the In this example, the diesel engine 1 is mechanical via the pump transfer case 2 connected with each other. When the critical drive torque arises Swing pump 3 is this moment no longer to the diesel engine 1 but to the Main pump 15 delivered.
