Definitions

  • the invention relates to a single-lever actuating device with a lever mounted on a pivot pin and a pivotably mounted actuating element which has a guide slot which consists of a curve section running concentrically to the pivot pin and a curve section angled relative thereto and in which the lever is guided in this way that when the lever enters the angled curve section, the actuator is pivoted, the lever being able to assume at least three positions I, II, III and the position being assigned to one end of the concentric curve section to which the angled curve section connects, the position II is assigned to the other end of the concentric curve section and position 111 is assigned to the angled curve section.
  • This known single-lever actuating device (FR-A-1 586 367) is used to adjust a supply air flap and a distribution flap in an air conditioning system of motor vehicles in such a way that when the lever moves in the concentric curve section of the guide slot, the supply air flap, which is connected to the lever by a cable , is pivoted towards its closed position, the position of the distributor flap being maintained.
  • the distributor flap is only adjusted when the lever enters the angled curve section and also adjusts the actuator to which the distributor flap is connected via a cable.
  • a single-lever adjusting device under the action of a spring is also no longer new (AU-B-39 034). It has a lever which can be pivoted between two positions and is mounted on a pin and is used to engage and disengage a clutch, via which a motor of a boat is connected with a screw. The lever is guided in a fixed backdrop, at one end of which a grid point is provided. The backdrop itself cannot be swiveled.
  • the lever can automatically move into position I, in which the drive for the cutting unit and possibly for the elevator conveyor is switched off, if blockages occur. Quick stops as such are common in combine harvester manufacturing.
  • Locking can be achieved in a simple manner if grid points are provided in the region of the guide slot or on an outer guide track of the actuating element arranged concentrically to the guide slot, for receiving a pawl pivotably mounted on the lever, the grid points being designed as grooves and positions II and 111 are assigned to the lever.
  • the lever for receiving a linkage connected to the pawl can have an axial bore and a spring can be provided on the linkage between the pawl and the lower end of the lever.
  • the spring is to be arranged so that the pawl automatically engages in the groove assigned to position II and disengages when the linkage is pressed, so that the lever; without it having to be pivoted manually, it snaps back into position I, in which it rests against the abutment and the drive is switched off.
  • Security is further improved in that a stop is provided on the actuator at a distance from the abutment, which forms a z-shaped passage for the pawl with the abutment. In this way, the operator is forced to manually guide the lever or its pawl through the passage path, for which purpose the pawl has to be pivoted upward again.
  • the actuator can expediently be designed as a double-armed lever, one lever arm having the guide slot and the guideway and being connected to the other lever arm in the shifting cable for actuating a clutch.
  • a shift cable for actuating a control valve of a hydraulic working element is also advantageously connected to the lever arm with the guide slot.
  • 10 in FIG. 1 denotes a single-lever actuating device for switching two clutches (not shown in the drawing) and a hydraulic motor of a motor vehicle, for example a combine harvester.
  • the single-lever adjusting device 10 consists of a lever 12 which is formed from a cylindrical tube 14 which is fixedly arranged on a lever arm 16.
  • a holder 18 is provided in the combine, on which the lever arm 16 is mounted by means of a pivot pin 20.
  • a second lever arm or an adjusting part 22 connects to the lever arm 16 and is connected to a clutch, not shown in the drawing.
  • the clutch is seated between a drive, also not shown in the drawing, for a cutting unit and for an inclined conveyor and a belt transmission, which is connected to the internal combustion engine of the combine harvester via further belt transmissions.
  • a drive also not shown in the drawing
  • a belt transmission which is connected to the internal combustion engine of the combine harvester via further belt transmissions.
  • the lever 12 In the position shown in FIG. 1, the lever 12 is in its neutral position, ie the clutch which can be actuated via the actuating part 22 is disengaged, so that the drive for the cutting mechanism is interrupted.
  • a second bracket 24 provided in the combine harvester serves to pivotally accommodate an actuator 26 which is connected to the bracket 24 via a pivot pin 28.
  • the actuator 26 is also designed as a two-armed lever arm, the lower, smaller lever arm 30 being connected to an actuating part or shifting cable 32, via which a clutch, also not shown in the drawing, can be actuated, which between the drive for the cutting unit and the inclined conveyor for a combine harvester and a hydraulic motor for reversing the drive is arranged. If the lever 12 assumes the position shown in FIG. 1, the clutch which can be actuated via the shifting cable 32 is also disengaged and the drive is interrupted.
  • the upper lever arm 34 connected to the lever arm 30 consists of a circular arc segment with an outer guideway 36, in which two grooves 38 and 40 arranged at a distance from one another are embedded.
  • One groove 40 is located between the pivot pin 28 and an abutment 42 protruding from the guideway 36, against which a pawl 44 pivotably mounted on the lever arm 16 can be brought into contact.
  • a third groove can also be provided in addition to the groove 40.
  • the pawl 44 is fastened on one side of the lever arm 16 by means of a bolt 46.
  • the free end of the pawl 44 consists of an inwardly bent nose 48, which comes to bear against the abutment 42 in the neutral position of the single-lever adjusting device 10.
  • the nose 48 opposite end of the pawl 44 is movably connected to a linkage 50 which is slidably received in the tube 14 of the lever 12 and has an operating button 52 at its upper end, via which the lever 12 pivots about its pivot pin 20 and over which the linkage 50 can be adjusted in the axial direction of the tube 14.
  • the control button 52 has a projection 54 which projects into the upper end of the tube 14 and thus radially fixes the linkage 50 in the tube 14.
  • a tension spring 56 on the linkage 50 which wants to pivot the pawl 44 in such a way that the nose 48 engages in the groove 38 or 40 or pressed against the surface of the guideway 36 becomes.
  • a stop 49 against which the nose 48 comes to rest and which prevents further adjustment of the lever 12 when the nose 48 has been pivoted upwards via the pawl 44.
  • the stop 49 is so spaced from the guide track 36 so that the nose 48 can move up to the abutment 36 through the gap 42 (see arrow 80) between the stop 49 and the guide track. This ensures that the lever 12 cannot be easily adjusted from its position II beyond position I to a position 111. Only when the nose 48 comes to bear against the abutment 42 can the nose 48 be pivoted upward behind the stop 49 via the pawl 44 and then the lever 12 can be brought into the position 111.
  • a guide slot 60 is provided in the curved lever arm 34 and serves to receive a cam or a roller 62 arranged on the lever arm 16.
  • the roller 62 is secured by means of a screw bolt 64 and a guide disk 68 running along the outside of the lever arm 34, so that the roller 62 cannot be guided out of the side of the guide slot 60.
  • the guide slot 60 provided in the lever arm 34 consists of two cam sections 70 and 72.
  • the cam section 70 extends between a lower end face 74 of the lever arm 34 to behind the groove 38.
  • the cam section 70 is arranged concentrically with the pivot axis of the pivot pin 28.
  • the radius for the curve section 70 is indicated by R 1 in FIG. 2.
  • the curve section 70 is followed by a smaller curve section 72, the radius R 2 of which increases continuously between points A and B with respect to the pivot axis of the pivot pin 28. If, for example, the roller 62 is moved out of the cam section 70 into the cam section 72, the actuator 26 is automatically also adjusted, and thus the lever arm 30 and the shifting cable 32 connected to the lever arm for actuating the clutch. The actuator 26 is thus positively guided via the lever 12.
  • the lever arm 34 also engages between the Pivots 28 of the actuator 26 and the roller 62 on a third actuator or a shift cable 76, which is automatically adjusted when the actuator 26 is adjusted.
  • a control valve for the hydraulic motor for the return or the reversing of the inclined conveyor and the cutting mechanism can be influenced via the control part 76.
  • a tension spring 78 is provided, which pivots the actuating part 22 in the counterclockwise direction and thereby presses the nose 48 against the abutment 42, so that the lever 12 is its in Fig. 1 shown neutral position I maintains.
  • the various positions of the lever 12 are shown. indicates the neutral position, II the operating position of the cutting unit and the inclined conveyor for the cutting device of the combine harvester and III the reversing position. If the lever 12 is to be pivoted from its neutral position I into the operating position II, it only needs to be pulled upwards, the nose 48 of the pawl 44 sliding along the guide track 36 until it engages in the groove 38 of the actuator 26 . When the lever 12 is pivoted into the operating position II, the clutch for the cutting mechanism and the inclined conveyor is engaged so that the drive to the traction mechanism drive driven by the internal combustion engine is produced and the cutting mechanism and inclined conveyor can operate normally.
  • the lever 12 can be adjusted from its operating position II into the reversing position III.
  • the control button 52 is pressed down so that the nose 48 releases the groove 38.
  • a direct adjustment of the lever 12 from position II to position III is to be prevented.
  • the abutment 42 is provided on the guide track 36, against which the pawl 44 comes to rest.
  • the stop 49 causes when the lever 12 is pivoted from the operating position II into the reversing position III that the lever 12 can only be pivoted beyond this position after a brief stop in the neutral position I, since even with the nose 48 completely pivoted upwards, this counter the stop 49 would come to rest. Only when the nose 48 comes to rest against the abutment 42 can the nose 48 be pivoted completely upward behind the stop 49 via the pawl 44 and thus the lever 12 can be adjusted to the position III. In this way, damage to the drive device and to the reversing gear mechanism can be eliminated, since it is impossible to move too quickly from position II to position III or vice versa.
  • the cam or the roller 62 is also moved into the curve section 72 of the guide slot 60 and the actuator 26 is thus also automatically adjusted.
  • the directional control valve associated with the control part 76 is also adjusted to a flow position via the control part 76, so that the hydraulic motor for driving the reversing gear can be supplied with pressure medium.
  • the position 111 engages the clutch between the reversing gear and the shaft or on the drive device for the cutting unit and for the feeder, so that the cutting unit and feeder can be driven in reverse and thus the material jam in the feeder housing can dissolve.
