Definitions
- the invention relates to a method for regulating in particular the pivoting device of a mobile machine, in particular a construction machine, such as a hydraulic excavator or the like.
- the object of the invention is to be seen in the fact that while maintaining the overall economy of the mobile machine, in particular the construction machine, the full power of the drive motor, in particular when braking masses, such as. B, an uppercarriage, can be used without the maximum speed of the drive motor being exceeded.
- This object is achieved by a method for controlling, in particular, the pivoting device of a mobile working machine, in particular a construction machine, such as a hydraulic excavator or the like, by driving a hydraulic pump operating in a closed circuit, in particular a pivoting circuit, via at least one drive motor, in particular a diesel engine, which in turn feeds at least one hydraulic motor, the energy of which is transmitted via a downstream, in particular mechanical transmission, to a mass to be accelerated or braked, in particular to a slewing ring of an uppercarriage which interacts with working equipment, with a target / actual comparison in particular when braking the mass the nominal and the limit speed of the drive motor is carried out and when a predeterminable speed, in particular the limit speed of the drive motor, the brake pressure is reduced in a closed circuit, in particular in the swivel circle.
- the subject matter of the invention includes several approaches.
- the current in particular the pilot control current, which acts in particular on the swivel hydraulics, can be reduced.
- the brake pressure in the closed swivel circle and thus the support torque on the drive motor, in particular the diesel motor decrease.
- a valve can be switched when the certain speed is exceeded, so that one or more main pumps have to deliver against a pressure relief valve.
- the swivel pumps, the main pumps and the drive motor, in particular the diesel motor, are mechanically connected to one another via a gear, in particular a pump distributor gear.
- a gear in particular a pump distributor gear.
- a possible failure of the drive motor, in particular the diesel engine, can thus be counteracted with both solutions, so that the power of the same can be fully used without adversely affecting the economy of the mobile working machine, in particular the construction machine.
- the subject of the invention is not only for braking rotatable masses, such as. B. the uppercarriage of the working machine, especially the construction machine, can be used. There is also the possibility of using the method for vehicles which, due to the descent, tend to cause the speed of the drive motor to move into critical areas and possibly to exceed them.
- Regulatory procedure 1 and 2 show different control methods of a swivel mechanism of a construction machine, not shown. The same components are provided with the same reference symbols.
- a diesel engine 1 designed as a drive motor can be seen, which is connected to a hydraulic pump 3 via a pump distributor gear 2.
- the hydraulic pump 3 feeds a hydraulic motor 4.
- the hydraulic pump 3 and the hydraulic motor 4 are operated in a closed swivel circuit 5.
- the power of the hydraulic motor 4 is transmitted to a mass 7, here an uppercarriage, not shown, of the construction machine via a swivel gear 6 connected downstream.
- Via a hand lever 8 provided in the cabin of the construction machine the swivel angle 3 ′ of the hydraulic pump 3 is changed via a hydraulic pilot control 9.
- the solution shown in FIG. 1 includes an electrical pilot control 10, which u. a. includes electronic components 11, 12.
- the component 11 is provided for the target / actual comparison of the nominal and the limit speed of the diesel engine 1, while the component 12 represents a control element by means of which the pilot current acting on the swivel hydraulics is reduced when the predetermined speed is exceeded.
- the braking pressure of the closed swivel circuit 5 and thus the supporting torque on the diesel engine 1 decreases.
- the control element 12 overrides the control element 13 interacting with the hand lever 8 or its current output, so that when the mass 7 is braked, the critical speed of the diesel engine 1 does not Case - not even when the operator actuates the lever 8 incorrectly.
- FIG. 2 shows a further variant of the regulation of a swiveling circle of a construction machine, which is also not shown.
- the electronic pilot control 10 ′ contains electronic components 11 ′ and 12 ′, the component 11 ′ being responsible for the target / actual comparison of the nominal and limit speed of the diesel engine 1.
- a valve (not shown) is switched via the control element 12 ', so that at least one main pump 14 has to deliver against a pressure relief valve 15.
- the swivel pump 3, the main pump 15 and the In this example, diesel engine 1 are mechanically connected to one another via pump transfer case 2.
- the critical drive torque of the swivel pump 3 arises, this torque is no longer delivered to the diesel engine 1 but to the main pump 15.
