Definitions

  • the invention relates to a soil cultivation machine, in particular a road milling machine, a stabilizer or the like, with a milling drum which is rotatably mounted on a machine frame and which is equipped or can be equipped with working tools on its outer circumference, the working tools being provided to be in contact during operation to step with the soil to be processed in order to remove it, a drive unit being provided which drives the milling drum by means of a drive motor, a drive shaft connected to the milling drum that can be coupled to the drive motor, and with a load element as a kinetic mass to increase the kinetic energy of the milling drum is provided.
  • Soil cultivation machines are known in various designs.
  • the DE 20 122 928 U1 a road milling machine as a soil tillage machine. It has a drive train. This comprises a drive motor, a clutch and a gear (the so-called milling drum gear), as well as organs that mediate these units, in particular shafts, toothed or endless drives.
  • working tools are understood to mean, in particular, structural units of the milling drum that functionally interact with the milled material during the work process.
  • these are the milling chisels with which the The subsurface is milled and / or ejector tools, which have a guiding and conveying function for the milled material.
  • the work result is significantly influenced by the speed of the milling drum.
  • the optimal speed generally depends on the application.
  • fine milling road surfaces to restore grip with a shallow milling depth, relatively higher speeds are required in order to generate a uniform milling pattern. Therefore, only a superficial treatment takes place here.
  • a high weight of the tillage machine helps to increase the smoothness even at low speeds. This is, however, disadvantageous in several respects, as it places special demands on the transport (large milling machines> 40 t; heavy transport) on the one hand and restricts the possibilities of use on statically less stable surfaces on the other.
  • a road milling machine in which a milling drum can be driven via a drive train.
  • the drive train includes, in particular, a drive motor, a clutch and a transmission (the so-called milling drum transmission).
  • the DE 10 2014 118 802 A1 now suggests on Drive train or on the milling drum as a kinetic mass to attach a load weight to increase the kinetic energy exchangeably.
  • the milling drum has, for example, pocket-shaped receptacles into which load weights can be inserted.
  • This road milling machine makes use of the knowledge that smoother running of the milling drum can be achieved if the kinetic energy in the drive train and / or the milling drum is increased.
  • m indicates the amount of the rotating mass and r the distance of this mass from the axis of rotation.
  • the product mr 2 represents the so-called moment of inertia of the moving mass and ⁇ the angular velocity (2 ⁇ * speed).
  • the milling drum can be individually adapted to the task at hand. However, a certain set-up effort is required here for adaptation.
  • the weights put a load on the drive motor and the coupling or the milling gear, especially when the machine starts up.
  • the object of the invention is to provide a soil cultivating machine of the type mentioned at the outset, which can be easily adapted to different milling applications and is characterized by a high degree of smoothness and, at the same time, low stress on the drive train.
  • the kinetic mass can be coupled or decoupled via a switchable coupling to the rotatable milling drum or to a rotating body that is directly or indirectly coupled to the milling drum.
  • the kinetic mass can either be coupled to or uncoupled from the milling drum via the switchable coupling, as desired by the machine operator.
  • the soil tillage implement is optimized for standard operation. If a change from this standard mode to lower speeds is to be made, the machine operator can conveniently switch on the kinetic mass via the switchable clutch in order to adapt the machine. Complex setup processes for adapting the machine can be avoided.
  • the kinetic mass is only coupled to the drive shaft or the bearing shaft when the milling drum is already in rotating operation. In this way, the milling drum can be started up without the kinetic mass being switched on. Accordingly, the kinetic mass then does not load the drive train with its own weight, in particular the drive motor, the gearbox or a shift clutch that mediates the drive motor and the gearbox. This simple measure extends the service life of the components of the drive train.
  • the speed can be reduced during operation with a simultaneous increase in the moment of inertia.
  • the required power consumption is reduced, which in turn leads to a reduction in fuel consumption and emissions from the drive motor leads.
  • With lower speeds there is also less bit wear and a lower coolant requirement.
  • the drive shaft or a bearing shaft arranged opposite the drive shaft, by means of which the milling drum is mounted on a machine frame forms the body of rotation.
  • the kinetic mass to the drive shaft or the bearing shaft, there is a lower structural design Effort required. In particular, there is usually sufficient space available at these points Available that enables the integration of the kinetic mass and the switchable clutch.
  • the kinetic mass is exchangeable. It can then in particular be exchanged for another kinetic mass with a different weight. This makes it possible to adapt the milling drum to any application situation. However, it is usually sufficient if a suitable kinetic mass is available that is suitably dimensioned to cover a wide range of applications.
  • the kinetic mass is coupled to the rotary body or the milling drum by means of a transmission gear, and that the transmission gear changes the speed at which the milling drum or the rotary body rotates to a higher speed at which the kinetic mass rotates, translated.
  • the transmission gear is designed as a switchable transmission with two or more transmission stages or as a transmission in which the transmission ratio is continuously variable. In this way, the speed can be varied in different stages (or continuously). This makes it possible to change the speed at which the kinetic mass rotates in order to change the moment of inertia acting on the milling drum and thus to be able to make a further adjustment to individual work requirements.
  • the bearing shaft or the drive shaft of the milling drum is guided directly to the drive side of the transmission gear. This means that there is minimal construction effort.
  • the bearing shaft or the drive shaft is guided indirectly to the drive side of the transmission gear with the intermediation of at least one rotating body.
  • a variant of the invention is particularly preferred such that the output side of the transmission gear is connected to the kinetic mass via the clutch. At this point, the kinetic mass can easily be coupled or uncoupled with little structural effort.
  • the rotating parts of the transmission gear also contribute to a certain extent to increasing the kinetic energy and stabilizing the milling operation, even when the kinetic mass is decoupled.
  • the switchable coupling is arranged between the bearing shaft and the input side of the transmission gear.
  • both the transmission gear and the kinetic mass can be decoupled at the same time.
  • the transmission gear In the uncoupled state, the transmission gear is not operated, which is a measure to optimize wear.
  • the invention can particularly preferably provide that the milling drum rotates at a speed in the range between 30 to 240 revolutions / min and the kinetic mass with a speed in the range between 60 to 4000 revolutions / min.
  • the speed of the kinetic mass is particularly preferably selected in the range between 1000 and 4000 revolutions / min. This preferred area is particularly suitable for use in road milling machines, since a very smooth running can be achieved here with a relatively low kinetic mass.
  • the dimensioning is advantageously carried out in such a way that the moment of inertia of the milling drum has a first value when the clutch is disengaged and that the moment of inertia of the milling drum when the clutch is engaged and the kinetic mass-absorbing assembly has a second value, the second value being at least twice as large as the first value.
  • a reliable compensation of imbalances in road milling applications can be achieved if it is provided that the moment of inertia of the kinetic mass is greater than or equal to T / i 2 , where T corresponds to the moment of inertia of the milling drum and i the speed ratio of the speed of the kinetic mass to the speed of the Milling drum is. It is immediately evident that a higher rotational speed can generate a greater effective moment of inertia on the drive side, since this is entered in the square.
  • the moment of inertia acting on the milling drum corresponds to the moment of inertia of the milling drum (as well as existing attachments such as parts of the drive train) plus the moment of inertia of the kinetic mass multiplied by the square of the speed ratio i.
  • an ideal transmission is assumed here.
  • a soil cultivating machine can be characterized in that the transmission gear is arranged at least in some areas in the installation space enclosed by the milling drum. In this way, the transmission gear is housed in a space-saving manner. In addition or as an alternative, it is also conceivable that the transmission gear is accommodated at least in some areas within a milling drum box. Such a construction is recommended if there is already sufficient installation space available in the area of the milling drum box, which enables the integration of the transmission gear. Of course, the transmission gear can also at least regionally be arranged within the milling drum box, at the same time it also protrudes at least in areas into the construction space surrounded by the milling drum.
  • the part of the transmission gear that is located in the milling drum box should then be protected from attack by the material removed from the milling drum box by suitable measures. If it is the case that the transmission gear protrudes at least partially into the installation space surrounded by the milling drum, then the milling drum geometry protects the transmission gear
  • the milling drum is at least partially accommodated inside the milling drum box, with the bearing shaft being arranged in the area of a side wall of the milling drum box, and that the transmission gear on the milling drum box is outside the interior space accommodating the milling drum, preferably on the outside of the Milling roller box, particularly preferably on the outside of the side wall, attached or arranged.
  • Such a procedure is recommended when a sufficiently large space for the transmission gear has to be made available on the side of the milling drum box. Because the transmission gear is arranged outside the milling drum box, it then of course no longer has to be protected from the excavated material.
  • the use of a transmission gear can be provided.
  • the invention is not restricted to this. Rather, it is also conceivable that the milling drum is coupled to the kinetic mass in the engaged state of the clutch in such a way that the speed of the milling drum corresponds to the speed at which the kinetic mass rotates, neglecting the slip of the clutch.
  • a particularly space-saving design can be achieved if it is provided that the coupling and the kinetic mass are arranged within the installation space enclosed by the milling drum.
  • a braking device can also be used which is designed to brake the kinetic mass when the clutch is in the open state, that is to say the kinetic mass is then decoupled from the milling drum. This prevents the kinetic mass from being moved as a result of drag torques within the clutch (for example in the case of viscous clutches).
  • the coupling can be arranged in the area between the transmission gear and the kinetic mass. This has the advantage that a more cost-effective, weaker clutch can be used.
  • the clutch is arranged in front of the transmission gear. Accordingly, when the clutch is disengaged, both the transmission gear and the kinetic mass are decoupled from the milling drum. Since the transmission gear no longer has to be moved in this operating state, there is a better degree of efficiency.
  • a monitoring device can also be provided which uses a detection unit to detect one or more machine states.
  • a vibration sensor and / or a torque sensor which detects a torque in the area of the drive train, in particular on the drive motor, can be provided.
  • the monitoring signal detected by the detection unit is fed to the monitoring device.
  • the monitoring signal is evaluated there. If there is an impermissible deviation from a default signal, a switching signal is generated by the monitoring device. This causes the switchable clutch to open using an adjusting element, for example an actuator. If an undesired machine condition occurs, the kinetic mass is then decoupled from the milling drum by actuating the switchable clutch.
  • Figure 1 shows a road milling machine 10 as a soil cultivating machine for milling road surfaces made of asphalt, concrete or the like.
  • the road milling machine 10 has a machine frame 11 with an operator's platform 12. On the operator's platform 12, the machine operator can operate the road milling machine and control the functions of the road milling machine.
  • the machine frame 11 is carried by a chassis 13.
  • the chassis 13 comprises, for example, four crawler tracks 14 which are arranged on the front and rear on both sides of the machine frame 11.
  • the chain drives 14 allow the road milling machine to move forwards and backwards along a lane.

  • the crawler tracks 14 on the one hand and the machine frame 11 on the other hand are fastened to these lifting columns 15. The machine operator can adjust the height of the machine frame 11 with respect to a roadway by adjusting the lifting columns 15.
  • the road milling machine has a working unit which is a milling device with a milling drum 30.
  • the milling drum 30 is equipped with working tools 31.
  • the work tools 31 are attached to the milling drum 30 in an exchangeable manner by means of holding arrangements, for example chisel holders or chisel holder changing systems.
  • the milling drum 30 is arranged on the machine frame 11 between the front and the rear chain drive 14. It goes without saying that the invention is not restricted to use in such types of machines, usually referred to as large milling machines. Rather, it is also conceivable that the milling drum 30 is arranged between the rear drives. Such machine types are usually referred to as compact or small milling machines.
