Definitions

  • the invention relates to an operating linkage with shift levers for control valves of a vehicle, in particular a grader, the control valves being connected to hydraulically actuated elements via connections.
  • each shift lever is assigned a specific function.
  • the object to be achieved with the invention is seen in making the assignment of the functions to the shift levers variable depending on the needs of the operator.
  • This object has been achieved according to the invention in that the connections of at least two control valves are interchangeable. Since, as a rule, the control valves are mechanically firmly connected to the shift levers, so that when the shift lever is actuated the associated control valve can also be actuated and the function A is triggered, the function B is achieved in this way by changing the connections when the same shift lever is actuated can be achieved, function A then being triggered again by actuating the other shift lever.
  • control console can also be designed pivotable depending on the type of vehicle, it is proposed according to the invention that the control valves are arranged side by side as a package and, if the control console is pivotable, be mounted fixed to the frame.
  • the shift levers used to lift the left and right ends of the dozer blade are arranged on the two outer sides of the shift lever group.
  • the first control valve on one outside of the valve package and the second control valve on the other outside thereof can expediently and third control valve next to the second control valve be n.
  • the side-by-side shift knobs of shift levers are often offset from one another in order to make it easier for the operator to grasp them.
  • the offset is in the direction of travel and results in gear levers bent differently. This may be annoying for an operator when relocating a function, which is why it is proposed according to the invention that the shift levers are arranged on the associated rod in an easily detachable manner, thereby giving the operator the possibility, for example, of related functions that have been placed side by side to use the same trained shift lever.
  • An easy detection is then favored if a corresponding spacer bush is provided between the shift levers of the same design.
  • knobs are provided with interchangeable symbols, so that if the functions have been changed, the new symbols can be attached to the shift lever without changing the shift lever.
  • an adjustable control console is designated 10, which can be arranged on a driver platform 15 of a vehicle, such as a motor grader, the driver's seat, not shown for the sake of simplicity, located immediately behind the control console or to the left of Fig. 1a the control console is located.
  • vehicle itself can be of conventional design, for example as described in US-A-3,450,213.
  • the control console 10 is arranged on a foot part 11, which has two transversely spaced plates 12 and 13, which in turn are arranged on the platform, in an upright manner and can accommodate a stand 14 which is pivotally mounted on the plates 12 and 13 is.
  • the stand consists in particular of first and second longitudinally spaced U-shaped wall parts 16 and 17, the lower ends of the wall parts being mounted in plates 12 and 13 via hinge axes 18 and 19.
  • the stand 14 is also provided with two upper hinge axes, of which only the rear one and shown at 22 is shown in the drawing, with reference to this is that in connection with the description of the actuating linkage this hinge axis is referred to as a rod.
  • the upper ends of the wall parts 16 and 17 are articulated to these hinge axes, and they likewise receive two transversely spaced T-shaped connecting plates 20 and 20a.
  • the adjustable control console 10 can be locked in any position via a locking unit (not shown), an unlocking device with a hand lever being used to release the locking unit. The control console 10 can then be pivoted via the hand lever.
  • control valves 27 are arranged, which are arranged in a package on a plate on the front part of the control station or the cabin.
  • Each control valve 27 is provided with a control arm 31 which can be swiveled up and down in a vertical plane and when it is actuated, then hydraulically actuated elements, for example hydraulic cylinders, are pressurized.
  • a control unit 33 with a steering wheel 34 and a steering column 36 and a hydraulic control device 37 is also arranged on the connecting plates 20 and 22, the control unit 33 being designed to be pivotable with respect to the stand 14 about a transverse shaft 38, which in turn is connected to the connecting plates 20 and 20a communicates.
  • a conventional hood is provided for covering the control unit 33 and can additionally accommodate necessary instruments for displaying the status of the various functions of the vehicle.
  • the control unit 33 is normally provided with a pivoting device, not shown in the drawing, which can be actuated independently of the angular position of the control console.
  • the operating linkage is provided with a shift lever group 46, which at the outer ends 52 and 53 of the upper Hinge axis are arranged, that is, the hinge axis is extended in the embodiment to the outside to accommodate the shift lever groups.
  • the shift lever group 46 is connected in an articulated manner to a connecting linkage 47 which extends downward from the shift lever group to an angle lever group 48 and is likewise articulated thereon.
  • the angle lever group 48 is pivotable on an axis 49, which can also be arranged in the plates 12 and 13.
  • a rod group 51 connects the angle lever group 48 to the corresponding control arms 31 of the control valves 27, as can be seen in FIG. 1b.
  • an associated valve 27 can be actuated such that the function connected to the control valve 27 is pressurized.
  • the shift lever group 46 consists of a plurality of shift levers 54 arranged side by side on the left and right ends 52 and 53 of the rod 22.
  • Each shift lever 54 has a shift arm 56 which extends upward as seen from a bushing 57, the bushing 57 being rotatably arranged on the ends 52 and 53 of the rod 22.
  • each bushing 57 also receives a swivel arm 58, which extends from the front in the direction of travel and is used for connection to the upper end of a connecting rod 59 from the connecting rod 47.
  • a knob 61 At the upper end of each shift lever 54 there is a knob 61 which can be easily grasped by the operator and which makes it easier to adjust the shift lever.
  • the shift levers 54 are arranged in two groups or their knobs in two different vertical planes net, the vertical planes lying one behind the other with respect to the direction of travel, so that the shift levers or their swivel arms 58 are bent differently.
  • This arrangement can easily be seen from Figs. 1a, 4 and 5. From Fig.
  • a bearing 66 is also provided, which also sits here between the wall part 16 and the innermost shift lever, a spacer bushing 99 being provided at the outer end, with the entire right group over a retaining ring 67 or the like is held on the right end 53 of the rod 22.
  • the shift levers can be easily removed by removing the locking ring 67.
  • control valves 27 are arranged in a package next to one another and extending transversely.
  • Each control valve 27 is provided with upper and lower connections 68 and 69, via which hydraulic fluid can be directed to the elements to be hydraulically acted upon.
  • a priority valve is indicated at 70 and special valves are indicated at 71, 72 and 73, these special valves being designed in such a way that they can generate a floating position for the associated function which they control.
  • the consumers or the functions can be acted upon on one side or on both sides. For the description below, however assumed that it is functions that can be acted upon from one side, the connections 69 and 69 'leading to the consumer.
  • connection 69 ' is shown in an exploded view.
  • the connection 69 ' can be screwed into a threaded housing channel 74 and has an orifice plate 76 with a slot 77, an O-ring 78, a pipe section 79, an O-ring 80 and a connecting nut 81 and a hydraulic line 82, which is connected to the connecting nut 81 in a conventional manner.
  • a first position of the knobs 61 of the shift lever 54 is shown and the knobs there designated 83, 84, 85 and 86 and lying on the left are directly connected to the valves 73, 87, 88 and 89 of the 2, while the switching levers 54 belonging to the knobs 91 to 95 and arranged on the right-hand side belong to the control valves 27 denoted by 96, 97, 98, 72 and 71 in FIG. 2.
  • the control valve 27 denoted by 73 in FIG. 2 is connected to a cylinder, not shown in the drawing, which serves to raise or lower the left end of a dozer blade while the control valve 72 is connected to another consumer, and the control valve 71 to one is also connected in the drawing, not shown cylinder, which serves to raise or lower the right end of the dozer blade.
  • the control valves 71 and 73 required to act on the cylinders are provided at each end of the valve package, so that the associated shift levers or their knobs 83 and 95 are also located on the right and left ends 52 or 53 of the rod 22, ie they are located on the very outside. To raise or lower the dozer blade, the operator must therefore usually work simultaneously with the right and left hand, if necessary.
  • the invention provides that the operator can then operate these two valves with a single hand, the following description assuming that it should be the right hand.
  • the ports 68 and 69 ', the control valves 73 and 52 are simply replaced. If the connections 68, 69 'are identical, the connections need only be removed from one control valve 72 and inserted into the control valve 73 after the connections have also been removed there, which are then subsequently used in the control valve 72.
  • control valve 73 which was used in the two-handed operation of the cylinder for raising and lowering the left side of the dozer blade, is connected to the consumer, while the control valve 72, which was connected to the consumer in the two-handed operation mode, is now connected to the cylinder Raising or lowering the left end of the dozer blade is connected.
  • the shift levers 54 required to actuate these two cylinders are now next to each other on the right side of the steering wheel 34, the shift lever required to actuate the consumer being on the outer left side.
  • the shift levers lying on the outside right side lie in two different vertical planes, i.e. they are shift levers that are bent differently.
  • the knobs are in the same vertical plane as shown in FIG. 6, the knobs assigned to the corresponding shift levers being designated 83 and 95.
