Definitions

  • the present invention relates to a work machine, in particular a wheel loader, having at least one cabin, which has at least one car door, which is pivotally mounted on the cabin frame by means of at least one hinge arrangement, wherein the hinge arrangement at least one frame part, which is arranged on the cabin frame and at least one relatively to the frame part rotatable door part, which is arranged on the car door has.
  • the door is pivotally mounted on the cabin by means of at least one hinge assembly.
  • Such an embodiment is for example from the DE 10 2014 015 711.3 known.
  • the present invention is therefore based on the object to further develop a working machine of the type mentioned in that their hinge assembly can be mounted in a simple manner reliably and in the desired position.
  • the use of gauges or other additional aids can be dispensed with.
  • the rod ensures that the hinges open and close smoothly and that distortion of the hinge assemblies relative to each other is eliminated.
  • the hinge assemblies each have frame portions that extend in the same direction as the rod, i. the frame members, such as inboard hinge members, are aligned in a preferred embodiment with said rod extending between the two (or more than two) hinge assemblies.
  • At least one of the hinge assemblies is a lifting hinge. This is understood to mean that this causes a stroke movement of the door part relative to the frame part during an opening movement of the car door.
  • a hinge By such a hinge, the door is raised altogether, which brings with it the advantage that it does not interfere with the pivoting movement or in the open state with components, such as a rise, etc. of the machine.
  • a further hinge arrangement is a simple rotary hinge and has no lifting functions.
  • a hinge is here understood to mean a hinge in which a first part rotates about a second part when the car door is opened, without this causing a lifting movement of one hinge part relative to the other hinge part.
  • At least one first hinge arrangement is arranged above the at least one second hinge arrangement, wherein the upper hinge assembly is said lift hinge and the second hinge assembly is said simple rotary hinge.
  • a single rotary hinge basically several hinges can be used.
  • a plurality of lifting hinges can be used, however, a preferred embodiment of the invention is that only exactly one lifting hinge is used per door.
  • the rod is a metal rod and preferably a steel rod, wherein it is preferably provided that the rod is designed as a whole or at least partially.
  • the rod has the task of fixing the fixed elements, i. the frame parts of the two or more hinge assemblies always keep in the desired position relative to each other, which requires a correspondingly stable configuration of the rod.
  • the frame part of the hinge may have at least one inner part surrounded by at least one outer part of the door part, said rod preferably having a diameter which is in the range of +/- 20% of the diameter of the inner hinge part.
  • the invention thus also encompasses the part in which the rod has a diameter which substantially or exactly corresponds to the diameter of the inner part of the frame part of the hinge.
  • frame part is any fixed part of the hinge assembly to understand and “door” each movable with the door part of the hinge assembly.
  • the rod is connected by a non-positive and / or by a positive connection with the frame parts of the at least two hinge assemblies.
  • the lifting hinge has at least one inner part, with which said rod is connected and at least one outer part, which is rotatable relative to the inner part, wherein the inner part is provided with one or more bolts, the run in one or more grooves of the outer part or vice versa.
  • the inner part may have one or more bolts running in grooves of the outer part or, conversely, the outer part one or more bolts running in one or more grooves of the inner part.
  • bolt is to be understood generally and includes any projection, such as a ball, roller, etc., which runs in a groove or the like.
  • the rod can also advantageously be made in two parts or consist of more than two parts, with different parts in material and / or material class differ.
  • the advantage of this arrangement is that the respective lower hinge manages without further coverage.
  • the first part of the rod is cost-effective a metal rod, preferably a steel rod and a second part is guided by the lower hinge, a stainless rod, preferably used in stainless steel execution.
  • connection of the two parts can be done either via an additional intermediate part, which is connected by way of example with two parts non-positively, or it is the first part and the second part of the rod overlapping manufactured so that the outer diameter of the two rod parts are about the same size, however the inner diameters of both parts differ noticeably.
  • the different inner diameters of the two parts result from force entries in the region of the sleeve, which are removed via the frame fitting part.
  • the second part is preferably not a full part, since this requires a higher weight, a machining in the region of the screw connection with the frame fitting part and thereby makes the entire rod more expensive.
  • any other suitable material may also be considered for the rod, e.g. GfK.
  • the lifting hinge has at least one inner part with which the rod is connected and that the inner part also has at least one cavity in which a damper is arranged.
  • This damper has the task of the door movement, at least in the end region, i. To dampen in the almost open and almost closed state and this has the advantage that the door does not hit or only muted.
  • the lifting hinge may have at least one cover, which is arranged, so that the inner part is at least partially shielded from the environment when the door part is raised.
  • This cover may e.g. be designed as a cup or pot or as a bellows.
  • the cover is firmly fixed only in one end, and freely rotatable at the other end to avoid torsional stresses.
  • FIG. 1 shows by the reference numeral 10, the cab of a working machine, in particular a wheel loader. At the car 10, a door 20 is struck, which allows access to the cabin interior in the open state and closes the cab 10 in the closed state.
  • Reference numeral 30 denotes an upper hinge assembly and reference numeral 40 a lower hinge assembly.
  • the door 20 is pivotally attached to the cab 10 by means of both hinge assemblies 30, 40.
  • the upper hinge assembly 30 is designed as a lifting hinge, which should be understood that a rotational movement of the door is coupled from the closed to the open position with a lifting of the door.
  • the lower hinge assembly 40 is not arranged as a lifting hinge, but essentially comprises a door part which is arranged on the door and which surrounds with a sleeve-shaped portion a rod which is fixed to the car.
  • the two hinge assemblies are connected by a rod 50 with each other, which in turn each with a fixed part, ie not connected to the door moving part of the hinge assemblies, eg non-positively and / or positively and / or materially connected.
  • FIG. 2 shows the upper hinge assembly 30 in a sectional view.
  • the upper hinge assembly 30 includes an outer member A which is fixedly connected to a door fitting 32 and which is rotated with the door.
  • the slide member 60 Within the outer part A are the slide member 60 and in a cavity formed by this damper 70, which prevents the door strikes unrestrained when reaching their end positions.
  • the link member 60 may be provided with one or more projections which run in inclined grooves of the outer part A, so that the results in a relative movement between the link member 60 and the outer part of a vertical movement of the door.
  • the reverse embodiment projects on the outer part and grooves on the cam member) is included in the invention.
  • the reference numeral 31 denotes the frame fitting part, with which the upper hinge assembly is fixedly fixed to the car.
  • the rod or an intermediate part 51 arranged in the end region of the rod is non-rotatable and preferably non-positively and / or positively connected.
  • the intermediate part 51 is pressed into the upper end region of the tubular rod 50.
  • the intermediate part 51 is pressed with the sliding member 60.
  • the intermediate part 51 extends from below into a cavity of the sliding part 60.
  • FIG. 3 shows the upper hinge assembly in a different perspective and illustrates in particular the angular design of the frame fitting part 31st
  • FIG. 4 shows a sectional view through the lower portion of the upper hinge assembly 30. It is clear that in addition to the said compression between the intermediate part 51 and the link member 60, a positive connection is achieved by a bolt 80. This penetrates the intermediate part 51 and the slide member 60 and thus also ensures a rotationally fixed connection between the two parts.
  • FIG. 4 also results that the intermediate part is dimensioned on one side so that it can be accommodated in the end region of the rod 50 and dimensioned on the other side so that it can be accommodated in the cavity of the slide 60.
  • FIG. 5 a sectional view through the lower hinge assembly 40 can be seen.
  • This comprises a frame fitting part 41, with the rotatably a pipe 90 is in communication, which may be designed as a stainless steel pipe. Partially or completely around this tube 90 extends the clamp or sleeve 100, which is fixedly connected to the door fitting part of the lower hinge assembly 40. Like this FIG. 5 further, the tube is made in its upper end with a smaller diameter, so that it can be received in the rod 50 and pressed with this.
  • the ratio of outer diameter to inner diameter is preferably less with respect to the rod 50 than with the tube 90, which has a comparatively small inner bore and a relatively large material thickness.
  • guide sleeves and sealing rings can be fitted between the sleeve and the clamp, and meanwhile lubricant supply means (all not shown) can be attached.
  • FIG. 6 shows finally the entire arrangement of upper and lower hinge assembly and the rod 50, which is connected between each fixed, that is not moving with the door parts of the hinge assemblies, for example by traction or positive engagement or otherwise.
  • the entire in FIG. 6 shown arrangement first fixed to the door by means of the door fitting parts and then screwed together on the cabin, riveted, etc.
