Definitions

  • the invention relates to a motor grader with a forwardly extending main frame, on which a saddle is arranged for receiving hydraulic cylinders which are used to adjust a grader blade, the saddle being formed from at least one horizontally and at least two vertically running frame parts which partially surround the main frame.
  • a motor grader of the type mentioned at the outset is already known (US Pat. No. 3,986,563), which has a main frame for receiving an adjustable grader blade, which for this purpose is pivotally connected to cantilever arms via hydraulic cylinders.
  • the individual extension arms are connected to a bracket that completely surrounds the main frame and is then welded to it.
  • very complex welding work is necessary, which must also withstand extreme loads, such as shear forces.
  • the invention has for its object to provide the bracket or the individual fastening parts for receiving the hydraulic cylinder of the grader blade in such a way that they can be easily attached to the main frame and can also be exposed to extreme loads.
  • This object is achieved by the features listed in the characterizing part of claim 1. Due to the advantageous design of the saddle, it can be easily placed on the main frame from above and connected to the main frame by means of transverse bolts, so that the saddle can also withstand extreme loads, since additional support for the saddle is easy the main frame by means of bolts.
  • the saddle according to claim 2 from a front and a rear frame part is formed, which have a sufficiently large distance so that a better distribution of forces on the main frame takes place when the main frame is subjected to pressure or tensile stress.
  • each frame part which is kept at a distance via the horizontally extending plate, is detachably connected to the main frame by means of a bolt, which is connected to the main frame by the corresponding legs and then by in the side walls provided holes are inserted in the main frame.
  • the saddle can also be formed from an upper and a lower U-shaped frame part, which are brought up to the main frame from the top and the bottom, respectively, until the legs of the respective frame parts, which run parallel to one another, bear against one another. Then only the corresponding screw bolts need to be inserted or screwed into the legs in order to obtain a good connection between the upper and the lower frame part.
  • a good fixation of the individual frame parts or fastening parts of the saddle can be achieved by providing recesses in the area of the upper and lower corners of the side parts of the main frame, which are used to accommodate counterparts provided on the frame parts. This creates a perfect fit for the frame parts or fastening parts of the saddle on the main frame.
  • screw bolts can be inserted into the outer ends of the bolts for this purpose, said bolts releasably connecting the bolts to the main frame.
  • a motor grader is designated by 11 in FIGS. 1 and 2, which consists of a tractor part 13 and a main frame 17 that can be supported on wheels 15 and 21.
  • the main frame 17 is connected to the tractor part 13 in a horizontally pivotable manner by means of a joint device 19.
  • a driver's cab 23 provided on the tractor part 13 there are the operating devices by means of which the various hydraulic devices are installed the motor grader and the control devices can be operated.
  • a grader blade 24 is arranged on a rotating ring 25 below the main frame 17.
  • the turntable 25 has an inner ring gear which can be rotated by means of a hydraulic motor 29 arranged on a pull frame 27.
  • the front end of the pull frame 27 is pivotally connected to the main frame 17 by means of a universal joint device 28, while the rear end of the pull frame 27 is connected to the slewing ring 25.
  • a saddle 31 is arranged on the main frame 17 (see FIGS. 2 to 5).
  • a first Y-shaped support device 33 has an articulated arm 35 which is connected in an articulated manner to the saddle 31 and for this purpose is received between a front and rear frame part 37 and 39.
  • the other articulated arm 41 of the carrying device 33 is articulated at one end to a cross member 43.
  • a second carrying device 45 like the carrying device 33, is equipped with an articulated arm 47, which is also articulated between the frame parts 37 and 39 of the saddle 31.
  • the carrying device 45 also has a second articulated arm 49, which is also articulated to the cross member 43.
  • the carrying devices 33 and 45 are provided on both sides of the main frame 17.
  • the grader blade carrying device with its joint devices is designated 51 overall and consists of the joint devices 33 and 45, the cross member 43 and retractable and extendable hydraulic cylinders 53 and 55, the piston rods of which are connected to the carrying devices 33 and 45 via joints 57 and 59.
  • the piston rods of the hydraulic cylinders 53 and 55 are connected at the ends to the pull frame 27 by means of joints 61 and 63, respectively.
  • a retractable and extendable hydraulic cylinder 77 is also included means of a universal joint 79 connected to the pull frame 27 at one end.
  • the hydraulic cylinder 77 runs diagonally and transversely to the main frame 17, so that the piston rod 81 can be connected in an articulated manner to the arm 49 of the carrying device 45 by means of a universal joint 83.
  • the carrying device 45 has numerous openings or bores 85 directed towards the front, which are arranged at a distance from one another and serve to connect a locking bolt 87.
  • the connecting device or the locking bolt 87 is described in detail in US Pat. No. 3,986,563.
  • the locking bolt 87 can be inserted into the corresponding bores 85 of the cross member 43.
  • the main frame 17 is provided with a first pair of vertically extending, upwardly open recesses 100 for receiving and fixing the saddle 31, which are in the area of the upper edges of the left and right side walls 102 and 104 of the main frame 17 are provided and which lie on the same transverse plane.
  • a second pair of upwardly facing recesses 106 are provided in the area of the upper edge of the left and right side walls 102 and 104.
  • the recesses 106 lie behind the recesses 100.
  • a third pair of vertically aligned recesses 108 is provided in the region of the lower edges of the left and right side walls 102 and 104 of the main frame 17 and is also on the same transverse plane.
  • the cutouts 108 are located below the cutouts 106.
  • the cutouts 100, 106 and 108 are formed, for example, by milling out of the main frame 17 and serve as a seat for the frame parts 37, 39.
  • the side walls 102 and 104 of the main frame 17 have a rear bore 110 and a front bore 112.
  • the bores 110 are arranged in the side walls 102 and 104 on a same transverse plane, similar to the Boh stanchions 112.
  • the bores 110 and 112 lie close to the longitudinal central axis of the main frame 17.
