Definitions
- Braking device for a part that can be moved via a drive
- the invention relates to a braking device for a part that can be moved via a drive, in particular the rotary drive of the superstructure of a construction machine, with at least one variable displacement pump supplying at least one hydraulic motor with hydraulic medium in a closed circuit.
- DE-C 33 46 999 relates to a brake system for a part that can be moved via a drive, in particular the rotary drive of the superstructure of a construction machine, with an indirectly operating brake valve and a downstream spring-loaded brake cylinder, the force given off in the sense of braking onto the movable one Part acts.
- a stop which can be moved as a function of the pressure of the drive of the movable part is provided and which can be moved against the force of a return and rocking spring in order to restrict the adjustable range of the brake valve or to limit the pressure to lock the space of the spring brake cylinder.
- the linkage of the spring brake cylinder acts directly on the slewing drive of the superstructure.
- the disadvantage here is that the brake valve is mechanical, i.e. is actuated via a tread plate and a relatively large amount of construction work has to be carried out to achieve the braking effect.
- the movable parts which can be actuated by a drive are actuated by means of a closed hydraulic circuit
- an adjustment pump is used which on the other hand supplies the drive motor (traction motor, swivel motor or the like) with hydraulic medium.
- the drive motor traction motor, swivel motor or the like
- the variable displacement pump is brought towards zero by withdrawing a control lever or the like, with no medium then being conveyed here.
- braking elements such as mechanical brakes (multi-disc brakes for crawlers) or the like, must be provided in order to stop the respective moving part.
- the aim of the subject invention is to provide a braking device to pieren konzi ⁇ that no longer have the disadvantages of St.dT, is particularly simple in construction and is rüstbar in existing hydraulic circuits according ⁇ .
- the swivel lever of the variable pump can be swiveled back into the zero position of the variable pump and can be fixed there when the drive is braked by components acting on it.
- the invention includes both mechanical and hydraulically actuated locking elements in order to guide the pivoting lever of the variable displacement pump into the zero position and also to hold it there.
- the subject of the invention can easily be retrofitted to existing hydraulic circuits, the auxiliary pressure required for application being able to be removed from different areas of the hydraulic system, particularly when hydraulic locking means are used.
- hydraulic locking only two (retrofittable) cylinders are provided, which have the task of resetting the adjusting device (swivel lever) of the pump to zero and keeping it at zero.
- This solution is inexpensive and, as already mentioned, can be easily retrofitted. It points towards the St.d.T. the advantage that the braking effect can be much stronger, and that the swivel pump is always kept at zero, so that there is no longer any relative movement of the movable parts (crawlers, superstructure or the like) to the fixed part.
- the subject matter of the invention makes it possible to dispense with any further mechanical brakes, so that only a parking brake appears to be required when the device is at a standstill.
- the moment of inertia or the moment of inertia of the part still in motion when braking (crawlers, superstructure or the like) are braked in a very short time, so that they can no longer have a disadvantageous effect.
- the subject matter of the invention is illustrated below using an exemplary embodiment and is described as follows:
- the single figure shows a schematic diagram for the swivel drive of the superstructure, not shown, of a construction machine.
- the shift lever 1 which is designed as a hand lever and is provided for the swivel drive, can be seen.
- the hand lever 1 interacts with a pilot control block 2, which in turn acts on a torque pressure control valve 3.
- a swivel pump housing 4 i.a. a feed pump 5, a variable displacement pump 6 together with swivel lever 7 and actuating cylinder 8 are arranged.
- a swivel motor 10 is supplied with hydraulic medium via line 9.
- the hydraulic medium is returned to the swivel pump 6 in the circuit via line 11.
- variable displacement pump 6 when the control lever 1 is deflected in one direction or the other, the variable displacement pump 6 would swivel out in one direction or the other via the swivel lever 7 and supply the swivel motor 10 with hydraulic medium, which in turn would then set the superstructure of the construction machine in rotation. If the control lever 1 is returned to its starting position, the adjusting pump 6 would be pivoted into its zero position via the pivot lever 7. However, since momentum and mass moments of inertia of considerable magnitude are still present as a result of the superstructure rotating, braking of the latter cannot therefore be brought about. Rather, the swivel motor 10 now becomes a pump and conveys the hydraulic medium in the direction of the variable displacement pump 6, which then moves it further in the circuit. If there were not other braking elements, such as mechanical brakes or the like, the uppercarriage would only be able to be stopped after a long time by the friction in the system.
- the subject matter of the invention includes a shuttle valve 12, which is connected to the lines 13, 14 of the pilot control block 2, and which is connected via a line 15 to a directional valve 16, which cooperates with a spring 17.
- a hydraulic medium at an auxiliary pressure is present at the directional valve 16 via a further line 18.
- two clamping cylinders 19, 20 are provided, the piston rods 21, 22 of which are provided on both sides of the pivoting lever 7 are.
- the clamping cylinders 19, 20 are connected to the directional valve 16 via a common line 23.
- the directional valve 16 is closed when the uppercarriage is pivoted and the tensioning cylinders 19, 20 are inactive.
- hydraulic medium flows not only via the pilot control block 2 to the pressure regulator 3 and the variable displacement pump 6, but also via lines 24 and 25 to the shuttle valve 12 and thus via line 15 to the directional valve 16, so that the pressure now present actuates the spring 17 and closes the outlet 26 of the directional valve 16.
- the hydraulic medium at this point with the specified auxiliary pressure can therefore not be conveyed further in the direction of the clamping cylinders 19, 20.
- the directional valve 16 is closed again by the pressure now present in the line 15 and the hydraulic medium present in the line 23 can flow into the container 27, whereby the tensioning cylinders 19 and 20 are simultaneously relaxed again and the variable displacement pump 6 can swing out again.
- the hydraulic medium which is under a specified auxiliary pressure (e.g. 60 bar), can be found in the hydraulics of the construction machine, in particular its pilot control.
