Definitions

  • a first object of the invention is to remedy these drawbacks by creating a new simple and economical manufacturing backhoe including a cabin reduced in size, accessible and removable from each side from the driving before
  • Figure 1 schematically shows a side elevation view of a backhoe according to the invention, controlled from the front console.
  • FIG. 3 schematically represents a top view similar to the Figure 2 of a backhoe according to the invention, in which the cabin and the arm telescopic have been omitted to highlight the relative arrangement of main mechanical components of the backhoe.
  • the chassis-beam 1 is a chassis comprising two longitudinal members 1a, 1b substantially parallel and spaced from each other at a spacing greater than the width of a telescopic arm 5 articulated on a support 4 comprising two plates parallel 4a, 4b of spacing less than that of the side members 1a, 1b.
  • the longitudinal members 1a, 1b comprising very thick metal plates are braced at the front by a front plate 1c cut to accommodate in the low position the telescopic arm 5 carrying a tool 6 such as a bucket 6a ( Figure 1) or forks 6b ( Figure 5) and by two plates 2c, 2d of bearing support 2e, 2f of oscillation of the front axle 2.
  • the plate 4b of the support 4 is advantageously constituted by a extension of the beam 1a, while the plate 4a of the support 4 is welded simultaneously with a force recovery plate 19 and a plate 19a upper bracing of the side members 1a and 1b.
  • This plate 19a also carries the supports of the hinge pin of the lifting cylinder of the telescopic arm 5.
  • the chassis 1 therefore comprises a front part and a rear part of substantially equal lengths: the support 4 of the telescopic arm is located the end of the front part, while the spar 1a is curved outwards and towards the rear of the rear part, so as to support jointly with the spar 1b a rear structure comprising an apron 8 on which the shovel is mounted rear 9.
  • Cab 11 contains a console 12 before driving, a swivel seat 13 and a rear console 14 for operating the rear shovel 9, mounted substantially along the longitudinal axis 7 of the backhoe.
  • the interior of the cabin 11 is accessible from both sides by means of steps 1h left and right located in front of the rear wheels left 3a and right 3b, respectively.
  • the upper part of the front console 12 is substantially wide equal to or less than that of the support 4 of the loader arm 5, and this support 4 extends in height so as to be at a level lower than that of the upper edge of said front console 12.
  • the rear console 14 is arranged behind and above the rear axle 3 in a position corresponding to direct visibility over the most close to the back shovel (Figure 5);
  • a cardan shaft 16a mounted at one end on the flywheel of the 16 transversely oriented diesel engine is coupled at the other end to a gearbox angle 16b.
  • the gearbox 20 is housed substantially in the center of the machine between the two longitudinal members 2a and 2b, in the front part of the chassis 1 and substantially under the support 4 of the telescopic arm 5. It drives the front 2 and rear 3 decks by through corresponding cardan shafts.
  • This particular housing arrangement of the gearbox 20 practically in the center of the machine, under the support 4 of the arm 5, provides a better mass centering and allows the chassis width to be limited to a value close to that of the gearbox 20, and at the strictly necessary space of the housing of the telescopic arm 5 in the low position between the side members 1a and 1b.
  • the special arrangement of the motor 16 and the gearbox 20 allows thus to design a machine with a short and narrow frame, which is very favorable for forward visibility and further improves handling.
  • the transmission from the engine to the gearbox can be carried out without using a cardan shaft, via a connection elongated connecting the motor shaft to the bevel gear with possible use of a splined shaft slidably engaged in a fluted drive sleeve.
